Background: Drug-coated balloons (DCB) have promising results in the management of in-stent restenosis (ISR), still their role remains a major challenge, and not well established in contemporary clinical practice. Aims: To provide a comprehensive appraisal of the efficacy and safety of DCBs in patients with in-stent restenosis (ISR). Methods: We searched PubMed, Scopus, web of Science, Ovid, and Cochrane Central from inception until 30 March, 2023. We included randomized controlled trials (RCTs) that compared DCB versus DES in ISR patients. Our primary endpoints were major adverse cardiac events (MACE) and late lumen loss (LLL). Secondary clinical endpoints were all-cause death, cardiac death, MI, TLR, TVR, and stent thrombosis, and angiographic outcomes were MLD, and in-stent binary restenosis. Results: Ten RCTs comprising 1977 patients were included in this meta-analysis. The incidence of MACE was 15.57% in the DCB group compared to 14.13% in the DES group, with no significant difference in the risk of MACE following DCB (odds ratio [OR] 1.04, 95% confidence interval [CI]: 0.87 to 1.44). Compared with the DES intervention, the risk of LLL was comparable to the DCB intervention (mean difference [MD] -0.08, 95% CI: -0.18 to 0.02), while the incidence of TLR was increased in the DCB intervention (OR: 1.54, 95% CI: 1.2 to 1.99). Conclusion: DCB was comparable to DES implantation is ISR patients regarding clinical outcomes, however it showed an increase in TLR events. Moreover, a RCT with large sample size and longer follow-up duration is warrened to validate these results. [ABSTRACT FROM AUTHOR]

This study investigated the effect of ticagrelor combined with nicorandil on endothelial function and coronary blood flow after percutaneous coronary intervention (PCI) in patients with ST-segment elevation myocardial infarction (STEMI). We retrospectively analyzed 300 STEMI patients who underwent emergency PCI, 150 in the observation group and 150 in the control group. The control group was given oral ticagrelor. The observation group received oral nicorandil along with the control group. A significant improvement in peak ejection rate (PER) and left ventricular (LV) ejection fraction (EF) occurred after the operation, while LV end-diastolic volume index (LVESVI), LV end-diastolic internal diameter (LVEDD), cardiac troponin I (cTnI), and creatine kinase myoglobin (CK-MB) were significantly reduced compared to the preoperative period. Improvements in cardiac function were significantly greater in the observation group than in the control group (p < 0.05). After the operation, both groups' serum nitric oxide (NO) and endothelin-1 (ET-1) levels were greatly higher and lower, respectively, during the preoperative period (p < 0.05). The observation group's serum NO level was significantly higher than the control group's, and its ET-1 level was substantially lower than the control group's (p < 0.05). There was a significant increase in thrombolysis in myocardial infarction (TIMI) flow grade 3 percentage and TIMI myocardial perfusion grade (TMPG) grade 3 percentage in the observation group in the immediate postoperative period compared to the control group, despite a significantly lower corrected TIMI Frame count (CTFC) (p < 0.05). 1 month postoperatively, major adverse cardiovascular events (MACE) incidence was significantly lower in the observation group than in the control group (χ2 = 3.914, p = 0.048). The preoperative combination of ticagrelor and nicorandil in STEMI patients undergoing PCI helped attenuate vascular endothelial function impairment, improved coronary blood flow, and promoted postoperative cardiac function recovery.

Background/Objectives: The impact of alcohol consumption and its restriction on clinical outcomes in patients undergoing percutaneous coronary intervention (PCI) remains elusive. We aimed to investigate the clinical outcomes in drinkers undergoing PCI. Methods: We included 77,409 patients who underwent PCI and a health check-up within one year of the PCI using a nationwide prospective database from the Korean National Health Insurance System. Primary outcomes were major adverse cardiovascular and cerebrovascular events (MACCE), a composite of all-cause mortality, myocardial infarction, coronary revascularization, and stroke. Patients were classified as non-drinkers, within-the-guideline (≤1 standard drink in women and ≤2 in men), and above-the-guideline drinkers based on drinking status at the first health check-up after PCI. Results: During a 4.0-year follow-up duration, MACCE incidence was 19.7% (n = 15,214) (4689 [6.1%] deaths, 1916 [2.5%] MI, 2033 [2.6%] strokes, and 10,086 [13.0%] revascularizations). Both within-the-guideline- (aHR [95%CI], 0.843 [0.773–0.919]) and above-the-guideline drinkers (0.829 [0.784–0.876]) had a lower MACCE risk than the non-drinkers. A characteristic J-curve relationship was observed between the frequency or body weight-adjusted alcohol consumption and MACCE risk, with the lowest risk in the once-per-week and a mild amount per body weight (≤0.33 g/kg/week) group. Drinking habits after PCI were associated with a lower risk of adverse cardiovascular outcomes; those who continued to drink before and after PCI had the lowest risk. Conclusions: Alcohol consumption was associated with a lower risk of adverse outcomes in patients undergoing PCI. Further studies with longer-term follow-up are warranted. [ABSTRACT FROM AUTHOR]

Background & Objective: Acute coronary syndrome (ACS) can be divided into subgroups of ST-segment elevation myocardial infarction (STEMI), Non-ST-segment elevation myocardial infarction (NSTEMI), and unstable angina (USA). Patients diagnosed with NSTEMI are either treated conservatively or early invasive strategy is adopted. In NSTEMI it is believed that either one or more vessel is transiently occluded or that the blood flow is critically reduced in a patent vessel i.e. subtotal occlusion. This study was conducted to find the angiographic characteristics of NSTEMI patients undergoing coronary angiography. Methods: This study was conducted in Department of Cardiology, Lady Reading Hospital Peshawar. It was Cross Sectional Study. Data was collected from 8th November 2022 to 8th May 2023. Consecutive non-probability sampling technique was used to collect data from the patients. Results: Total of 300 patients were studied. The mean age was 56.95 years ±1.176 standard deviation. Male patients were 201 (67%) and remaining were female. It was found that 51(17%) of total NSTEMI patients were having totally obstructed coronary artery (OCA) in one or more coronary arteries. In NSTEMI, non-obstructive CAD (<50%) were found in 81 (27%) of patients whereas 219 (73%) were having significant CAD. It was found that 40% were having single vessel CAD, 32% were having double vessel CAD and 28% were having triple vessel CAD. TVCAD was present significantly higher in advance age, Diabetes mellitus, hyperlipidemia and family history of CAD. Conclusion: Patients having NSTEMI are usually having multiple risk factors and having usually severe and multivessel CAD. [ABSTRACT FROM AUTHOR]

Introduction: The sheathless transradial (TR) technique is a novel approach that may offer potential benefits over the conventional TR approach. We aim to comprehensively investigate the safety and efficacy of sheathless versus conventional TR percutaneous coronary interventions (PCIs). Methods: We conducted comprehensive searches across PubMed, CENTRAL, Web of Science (WOS), Scopus, and EMBASE until July 2023. Pooled data were reported using risk ratio (RR) for dichotomous outcomes and mean difference (MD) for continuous outcomes, along with a 95% confidence interval (CI). PROSPERO ID: CRD42023443834. Results: We included 11 studies with 15,392 patients. The radial artery spasm (RAS) (RR: 0.26, 95% CI: [0.09, 0.77], p = 0.02) and cross‐over to the femoral site (RR: 0.28, 95% CI: [0.10, 0.81], p = 0.02) were significantly lower in the sheathless group. However, radial artery occlusion (RAO) (RR: 2.84, 95% CI: [1.78, 4.54], p < 0.0001) and success rate (RR: 1.011, 95% CI: [1.004, 1.019], p = 0.002) were significantly higher in the sheathless group. Also, we did not find a significant difference between both groups in all‐cause mortality (RR: 0.41, 95% CI: [0.16, 1.04], p = 0.06). Conclusion: The sheathless TR approach showed lower rates of RAS and femoral conversion. Sheathless has a higher success rate; however, it also increased RAO. Thus, more trials are needed to confirm this technique's long‐term outcomes and complications. [ABSTRACT FROM AUTHOR]

Elderly patients diagnosed with acute coronary syndromes (ACS) represent a growing demographic population. These patients typically present more comorbidities and experience poorer outcomes compared to younger patients. Furthermore, they are less frequently subjected to revascularization procedures and are less likely to receive evidence-based medications in both the short and long-term periods. Assessing frailty is crucial in elderly patients with ACS because it can influence management decisions, as well as risk stratification and prognosis. Indeed, treatment decisions should consider geriatric syndromes, frailty, polypharmacy, sarcopenia, nutritional deficits, prevalence of comorbidities, thrombotic risk, and, at the same time, an increased risk of bleeding. Rigorous clinical assessments, clear revascularization criteria, and tailored approaches to antithrombotic therapy are essential for guiding personalized treatment decisions in these individuals. Assessing frailty helps healthcare providers identify patients who may benefit from targeted interventions to improve their outcomes and quality of life. Elderly individuals who experience ACS remain significantly underrepresented and understudied in randomized controlled trials. For this reason, the occurrence of ACS in the elderly continues to be a particularly complex issue in clinical practice, and one that clinicians increasingly have to address, given the general ageing of populations. This review aims to address the complex aspects of elderly patients with ACS to help clinicians make therapeutic decisions when faced with such situations. [ABSTRACT FROM AUTHOR]

Purpose: The purpose of the present study was to find the independent predictors of Fractional Flow Reserve (FFR) measured immediately after percutaneous coronary intervention with drug-eluting stent implantation (post-PCI FFR) and investigate if applying vessel-specific post-PCI FFR cut-off values to predict target vessel failure (TVF), a composite of cardiac death (CD), non-fatal myocardial infarction (MI) and target vessel revascularization (TVR), or a composite of CD and MI ameliorated its predictive power. Methods: Consecutive patients with post-PCI FFR measurement at our center between 2009 and 2021 were included in this analysis. Results: A total of 434 patients with 500 vessels were included. Median pre-PCI FFR was 0.72 with no difference between LAD and non-LAD vessels. Median post-PCI FFR was 0.87. LAD location, male gender, smaller stent diameter, and lower pre-PCI FFR proved to be significant predictors of a lower post-PCI FFR. On a vessel-level, post-PCI FFR, stent length, and diabetes mellitus proved to be significant predictors of TVF and the composite of CD and MI. The best post-PCI FFR cut-off to predict TVF or a composite of CD and MI was 0.83 in the LAD and 0.91 in non-LAD vessels. Conclusion: LAD location is a predictor of a lower post-PCI FFR. Post-PCI FFR is an independent predictor of TVF as well as of the composite of CD and MI. No uniform target post-PCI FFR value exists; different cut-off values may have to be applied in LAD as opposed to non-LAD vessels. [ABSTRACT FROM AUTHOR]

Introduction: Patients with severe aortic stenosis referred for transcatheter aortic valve implantation (TAVI) often present with concomitant coronary artery disease (CAD). The management of CAD in these patients remains a topic of debate, encompassing the evaluation and timing of percutaneous coronary intervention (PCI). Areas Covered: This review article aims to offer an overview of the role of coronary revascularization in TAVI patients, highlighting the advantages and disadvantages of different strategies: PCI before, concomitant with, and after TAVI. Considering that TAVI indications are expanding and patients with low surgical risk are now being referred for TAVI, the rate of PCI among patients undergoing TAVI is expected to increase. Historically, PCI was performed before TAVI. However, there is now a growing trend to defer PCI until after TAVI. Expert opinion: It is plausible that in the future, there will be an increase in PCI after TAVI due to several factors: first, multiple studies have shown the safety of TAVI even in patients with severe untreated CAD; second, improvements in TAVI device implantation techniques, such as commissural alignment and patient-specific device selection, have improved access to the coronary arteries post-TAVI.

Modern gas chromatography-mass spectrometry (GC–MS) allows for the analysis of complex samples, such as fragrances. However, identifying all the constituents in natural fragrance mixtures, especially allergens that need to be listed on product labels, is a significant challenge. This is primarily due to the high complexity of the sample and the fact that electron ionization, the most commonly used ionization method in GC–MS, produces numerous nonspecific fragment ions, often resulting in the absence or very low abundance of the molecular ion. These factors affect confidence in assigning the analyte. In this study, we demonstrate that the combination of GC × GC separation, with high mass resolution and accurate mass measurements, as well as chemical ionization in addition to traditional electron ionization, becomes an efficient tool for reliable qualitative analysis of a mixture containing 100 fragrance allergens, even when many of them are closely related species or isomers. The proposed approach expands the applicability of the comprehensive GC × GC-HRMS method, which includes complementary ionization techniques, from studies on anthropogenic priority pollutants and emerging contaminants to the analysis of natural products. Although targeted qualitative and quantitative analysis of allergens in the modern laboratories is well organized, GC × GC-HRMS, being a useful complement to routine quality control of volatile allergens in fragrances, definitely gives an additional contribution to the analytical cases when conventional 1D-GC–MS faces some problems or uncertainties.

Objective: To investigate the relationship between systemic immune inflammatory index (SII), fibrinogen/albumin ratio (FAR), C-reactive protein/albumin ratio (CAR) and no-reflow during percutaneous coronary intervention (PCI) in patients with acute ST-elevation myocardial infarction (STEMI) and heart failure with preserved ejection fraction (HFpEF). Methods: 155 patients with STE- MI and HFpEF who underwent direct PCI in our hospital from May 2020 to May 2023 were prospectively selected, patients were divided into no-reflow group (n=35) and normal-reflow group (n=120) according to the blood flow during PCI. SII, FAR and CAR were calculated. The factors of no-reflow during PCI in patients with STEMI and HFpEF were analyzed by multivariate Logistic regression model, the predictive value of SII, FAR and CAR for no-reflow during PCI in patients with STEMI and HFpEF were analyzed by drawn receiver operating characteristic (ROC) curve. Results: The incidence of no-reflow during PCI in 155 patients with STEMI and HFpEF was 22.58% (35/155). Compared with normal-reflow group, SII, FAR and CAR increased in no-reflow group (P<0.05). The independent risk factors for no-reflow during PCI in patients with STEMI and HFpEF were increased age and increased SII, FAR and CAR (P<0.05). The area under the curve of SII, FAR, CAR alone and SII, FAR, CAR combined to predict no-reflow during PCI in patients with STEMI and HFpEF was 0.811, 0.800, 0.788, 0.940 respectively. Conclusion: The increase of SII, FAR and CAR in patients with STEMI and HFpEF is an independent risk factor for no-reflow during PCI, the combination of SII, FAR and CAR has a high predictive value for no-reflow during PCI in patients with STEMI and HFpEF.

Background: Ischaemic heart disease is one of the major drivers of cardiovascular death in Europe. Since the first percutaneous coronary intervention (PCI) in 1977, developments and innovations in cardiology have made PCI the treatment of choice for stenotic coronary artery disease. To address the occupational hazards related to chronic exposure to radiation and wear and tear from heavy lead-based radioprotective aprons, the concept of robotically assisted PCI (R-PCI) was introduced in 2005. Aim: To explore the features and limitations of R-PCI, we first discuss the concept and evolution of R-PCI platforms and then systematically review the available clinical data. Methods: A systematic review has been performed across the Pubmed, Embase and Cochrane databases in order to assess the efficacy and safety of R-PCI. Secondary endpoints, such as operator and patient exposure to radiation, contrast volume used and procedural time, were assessed when available. Results: In selected patients, R-PCI provides high technical and clinical success rates, ranging from 81 to 98.8% and from 93.3 to 100%, respectively. In-hospital and 1-year MACE rates ranged from 0 to 10.4% and 4.8 to 10.5%, respectively. R-PCI is able to significantly reduce the operator's exposure to radiation. Further research analysing the patient's and cath lab staff's exposure to radiation is needed. Therapy escalation with R-PCI seems to be limited to complex lesions. R-PCI procedures add approximately 10 min to the procedural time. Conclusions: The efficacy and safety of R-PCI have been proven, and R-PCI is able to significantly reduce occupational hazards for the first operator. The lack of adoption in the community of interventional cardiologists may be explained by the fact that current generations of R-PCI platforms are limited by their incompatibility with advanced interventional devices and techniques needed for escalation in complex interventions.

Myocardial infarction (MI) is a leading cause of mortality globally and is predominantly attributed to coronary artery disease (CAD). MI is categorized as ST-elevation MI (STEMI) or non-ST-elevation MI (NSTEMI), each with distinct etiologies and treatment pathways. The goal in treatment for both is restoring blood flow back to the myocardium. STEMI, characterized by complete occlusion of a coronary artery, is managed urgently with reperfusion therapy, typically percutaneous coronary intervention (PCI). In contrast, NSTEMI involves a partial occlusion of a coronary artery and is treated with medical management, PCI, or coronary artery bypass grafting (CABG) depending on risk scores and clinical judgment. The Heart Team approach can assist in deciding which reperfusion technique would provide the greatest benefit to the patient and is especially useful in complicated cases. Despite advances in treatment, complications such as cardiogenic shock (CS) and ischemic heart failure (HF) remain significant. While percutaneous coronary intervention (PCI) is considered the primary treatment for MI, it is important to recognize the significance of cardiac surgery in treatment, especially when there is complex disease or MI-related complications. This comprehensive review analyzes the role of cardiac surgery in MI management, recognizing when it is useful, or not. [ABSTRACT FROM AUTHOR]

Multivessel coronary artery disease is present in ∼50% of patients with acute coronary syndrome and, compared with single-vessel disease, entails a higher risk of new ischaemic events and a worse prognosis. Randomized controlled trials have shown the superiority of 'complete revascularization' over culprit lesion-only treatment. Trials, however, only included patients treated with percutaneous coronary intervention (PCI), and evidence regarding complete revascularization with coronary artery bypass graft (CABG) surgery after culprit lesion-only PCI ('hybrid revascularization') is lacking. The CABG after PCI is an open, non-negligible therapeutic option, for patients with non-culprit left main and/or left anterior descending coronary artery disease where evidence in chronic coronary syndrome patients points in several cases to a preference of CABG over PCI. This valuable but poorly studied 'PCI first-CABG later' option presents, however, relevant challenges, mostly in the need of interrupting post-stenting dual antiplatelet therapy (DAPT) for surgery to prevent excess bleeding. Depending on patients' clinical characteristics and coronary anatomical features, either deferring surgery after a safe interruption of DAPT or bridging DAPT interruption with intravenous short-acting antithrombotic agents appears to be a suitable option. Off-pump minimally invasive surgical revascularization, associated with less operative bleeding than open-chest surgery, may be an adjunctive strategy when revascularization cannot be safely deferred and DAPT is not interrupted. Here, the rationale, patient selection, optimal timing, and adjunctive strategies are reviewed for an ideal approach to hybrid revascularization in post-acute coronary syndrome patients to support physicians' choices in a case-by-case patient-tailored approach.

Forty percent of patients with acute coronary occlusion myocardial infarction (OMI) do not present with STEMI criteria, which delays their treatment and increases morbidity and mortality. The need to identify these patients promptly is crucial, and this sets the stage for the proposed reclassification. Many of these patients can be identified by other ECG and clinical features. Background/Objectives: We sought to evaluate cases of STEMI and NSTEMI that result in OMI. Additionally, we focused on the consequences of delayed revascularization in NSTEMI patients with acute coronary occlusion (NSTEMI-OMI). Methods: The study is a retrospective analysis conducted on 334 patients who underwent coronary angiography for acute coronary syndrome at UHC "Mother Teresa", Tirana, Albania, during January–May 2023. "OMI was defined as an acute culprit lesion with TIMI 0–2 flow, or an acute culprit lesion with TIMI 3 flow intervened upon and with highly elevated troponin (cTnI > 10.0 ng/mL, hs-cTnI > 5000 ng/L)". The presence or absence of STEMI criteria were determined in the final diagnosis written on the chart by a cardiologist using the third universal definition of MI. Ejection fraction (EF), total ischemia time, length of stay, and complications were compared between groups. Mechanical complications include acute ventricular failure, cardiogenic shock, rupture of the interventricular septum, rupture of the free wall, rupture of the papillary muscle, and pericarditis. Electrical complications include ventricular arrhythmias, supraventricular arrhythmias, and atrioventricular and interventricular blocks. Results: There were 334 patients included, 98 (29.3%) of whom were NSTEMI-OMI patients. Ninety-six patients (40%) of OMI patients did not fulfill the STEMI criteria. Only 11 patients (11%) of STEMI(−)OMI had PCI performed within the first 12 h vs. 76 patients (77%) with STEMI(+)OMI, p < 0.001. There was no difference in the percent of patients requiring PCI between the STEMI(+)OMI 98 patients (93%) and STEMI(−)OMI 87 patients (89%) (p = 0.496). The overall in-hospital mortality was 19 patients (5.7%), with subgroup mortality of 14 patients (4.2%) with STEMI(+)OMI, 2 patients (0.6%) with STEMI(+) NOMI, and 3 patients (0.9%) with STEMI(−)OMI, 0% STEMI(−)NOMI, (p = 0.013). Patients with mechanical complications included 67 patients (46.8%) with STEMI(+)OMI and 45 patients (46.4%) with STEMI(−)OMI. In addition, 26 patients (18.5%) with STEMI(+)OMI and 13 patients (13.1%) with STEMI(−)OMI developed electrical complications. Conclusions: STEMI(−)OMI patients had significant delays in catheterization, yet had angiographic findings, rates of PCI, and complications similar to STEMI(+)OMI. These data add further support to refocusing the paradigm of acute MI to improve recognition and rapid reperfusion of all OMIs, rather than only those with STEMI criteria. [ABSTRACT FROM AUTHOR]

The registry-based randomized VALIDATE-SWEDEHEART trial (NCT02311231) compared bivalirudin vs. heparin in patients undergoing percutaneous coronary intervention (PCI) for myocardial infarction (MI). It showed no difference in the composite primary endpoint of death, MI, or major bleeding at 180 days. Here, we report outcomes at two years. Analysis of primary and secondary endpoints at two years of follow-up was prespecified in the study protocol. We report the study results for the extended follow-up time here. In total, 6006 patients were enrolled, 3005 with ST-segment elevation MI (STEMI) and 3001 with Non-STEMI (NSTEMI), representing 70 % of all eligible patients with these diagnoses during the study. The primary endpoint occurred in 14.0 % (421 of 3004) in the bivalirudin group compared with 14.3 % (429 of 3002) in the heparin group (hazard ratio [HR] 0.97; 95 % confidence interval [CI], 0.85–1.11; P = 0.70) at one year and in 16.7 % (503 of 3004) compared with 17.1 % (514 of 3002), (HR 0.97; 95 % CI, 0.96–1.10; P = 0.66) at two years. The results were consistent in patients with STEMI and NSTEMI and across major subgroups. Until the two-year follow-up, there were no differences in endpoints between patients with MI undergoing PCI and allocated to bivalirudin compared with those allocated to heparin. Registration: URL: https://www.clinicaltrials.gov ; Unique identifier: NCT02311231. • A large-scale trial involving 6006 MI patients compared the outcomes of bivalirudin and heparin. • Two-year outcomes show no significant difference in MI patients treated with bivalirudin vs. heparin. • Consistent results were observed in both STEMI and NSTEMI patient groups. • Long-term follow-up confirmed similar safety and efficacy profiles for both drugs.

The aim of this systematic review and meta‐analysis was to comprehensively evaluate the latest evidences and summarise the impact of HIV on PCI outcomes. A PRISMA guided literature search was conducted on 14 February 2024 in Web of Science, PubMed, Virtual Health Library, Google Scholar and Scopus. We searched with the term '("percutaneous coronary intervention" OR "PCI") AND ("human immunodeficiency virus" OR "HIV" OR "acquired immunodeficiency syndrome" OR "AIDS")' after selecting the keywords from randomly chosen included papers. We included 8 papers of 781 screened records. HIV (+) patients had significant in‐hospital, 1‐year and overall (event at the last follow up point) all‐cause mortality compared to HIV (−) group (OR: 1.73, 95%CI: 1.57–1.90, p < 0.01), (OR: 1.39, 95%CI: 1.07–1.81, p = 0.01) and (OR: 1.69, 95%CI: 1.55–1.85, p < 0.01), respectively. HIV (+) patients had significantly higher odds of developing MACE (OR: 1.35, 95%CI: 1.12–1.62, p = 0.001) compared to the HIV (−) group. No differences between both groups were detected regarding in‐hospital and overall CV mortality, TVR, TLR, post‐PCI TIMI grade 3 flow, cerebrovascular accidents and recurrent coronary events (p > 0.05). Our study revealed that people with HIV who underwent PCI in this modern era may have worse short and long‐term PCI outcomes. This finding highlights the need for specialised cardiovascular care protocols for the HIV population. However, enhanced clinical management and preventative measures are imperative to improve PCI success rates in patients with HIV. [ABSTRACT FROM AUTHOR]

Die Frage nach der Leistung von Erwerbslosen und ALG II-Bezieher*innen für die Gesellschaft ist im öffentlichen Diskurs ein wiederkehrendes Thema, in dem den Betroffenen oftmals ein Fehlen dieser Leistung attestiert wird. Der Beitrag nimmt die subjektiven Deutungen von ALG II-Bezieher*innen selbst zum Ausgangspunkt: Mit Hilfe von problemzentrierten Interviews werden unterschiedliche Deutungen von Leistung herausgearbeitet und entlang ihrer Position zur Erwerbsarbeit gegenübergestellt. Damit zeichnet sich erstens eine Leistungsdeutung ab, die Leistung mit Erwerbsarbeit gleichsetzt (Erwerbszentrierung). Dem gegenüber, zweitens, steht die Abweichung von der Erwerbszentrierung als nur partielle Erwerbszentrierung (neben der Care-Arbeit) oder Alternativen zu ihr (Ehrenamt und Alltagsbewältigung). The public discourse around unemployment and benefit recipients typically revolves around what they do for society. Often, a lack of performance in this sense is ascribed to benefit recipients. In contrast to such external ascriptions, this article takes the subjective interpretations of unemployment benefit recipients into account. By employing problem-centered interviews, different interpretations of performance are reconstructed and compared according to their position on gainful employment: First, an interpretation of performance emerges that is congruent with the benefit regulation's focus on employment, which equates performance with employment. A second and contrasting perspective deviates from the focus on gainful employment, as only a partial focus on gainful employment (in addition to care work), or alternatives to it (voluntary work and coping with everyday life).

Background Previous studies in patients with ST-segment elevation acute myocardial infarction treated with primary angioplasty and supported by the PiCSO® system have shown a modest yet significant absolute reduction in the infarcted myocardial area. However, the simultaneous use of PiCSO® and Impella CP® during high-risk percutaneous coronary intervention (PCI) procedures has not been reported. Case summary A 76-year-old Caucasian man presented with severe and highly calcified left main coronary disease and severely depressed left ventricular function. As coronary bypass surgery was deemed prohibitive, successful PCI was performed with the simultaneous use of PiCSO® and Impella CP® to mitigate damage from distal microembolization and provide mechanical circulatory support to the left ventricle during the high-risk PCI procedure. Discussion Our case exemplifies for the first time the simultaneous use of PiCSO® and Impella CP® during a high-risk PCI. This case suggests the feasibility and safety of combining both devices for mechanical haemodynamic and microcirculatory support simultaneously in specific cases during high-risk PCI, offering hope for reducing post-PCI myocardial damage in a selected population of patients.

Abstract Background Drug-coated balloons (DCB) have promising results in the management of in-stent restenosis (ISR), still their role remains a major challenge, and not well established in contemporary clinical practice. Aims To provide a comprehensive appraisal of the efficacy and safety of DCBs in patients with in-stent restenosis (ISR). Methods We searched PubMed, Scopus, web of Science, Ovid, and Cochrane Central from inception until 30 March, 2023. We included randomized controlled trials (RCTs) that compared DCB versus DES in ISR patients. Our primary endpoints were major adverse cardiac events (MACE) and late lumen loss (LLL). Secondary clinical endpoints were all-cause death, cardiac death, MI, TLR, TVR, and stent thrombosis, and angiographic outcomes were MLD, and in-stent binary restenosis. Results Ten RCTs comprising 1977 patients were included in this meta-analysis. The incidence of MACE was 15.57% in the DCB group compared to 14.13% in the DES group, with no significant difference in the risk of MACE following DCB (odds ratio [OR] 1.04, 95% confidence interval [CI]: 0.87 to 1.44). Compared with the DES intervention, the risk of LLL was comparable to the DCB intervention (mean difference [MD] -0.08, 95% CI: -0.18 to 0.02), while the incidence of TLR was increased in the DCB intervention (OR: 1.54, 95% CI: 1.2 to 1.99). Conclusion DCB was comparable to DES implantation is ISR patients regarding clinical outcomes, however it showed an increase in TLR events. Moreover, a RCT with large sample size and longer follow-up duration is warrened to validate these results.

Abstract Purpose The conundrum of limited resources in developing countries leads to the abonnement and underutilization of percutaneous coronary intervention for chronic total occlusion, in addition to lack of expertise, limited supplies, and success rates. We embraced this challenge by initiating a dedicated program in a tertiary academic center in Egypt, aiming for optimum utilization of resources, limit cost, and gaining experience. We present our outcomes and the proficiency in establishing the program. Methods We enrolled all patients undergoing percutaneous coronary intervention for chronic total occlusion during the first year of initiating our dedicated program. Analysis of clinical data, angiographic findings, and procedural features were evaluated, aiming to evaluate outcomes. Our primary outcome was successful recanalization achievement, utilization of available resources and cost. Secondary outcomes such as peri-procedural myocardial infarction, coronary perforation, urgent need of coronary artery bypass grafting, cerebrovascular stroke, and mortality were assessed. Results Our study enrolled 64 patients electively admitted to the Critical Care Department, Cairo University, undergoing percutaneous coronary intervention for chronic total occlusion. The median J-CTO score was 2 (0–5). We achieved successful recanalization in 47 patients (73%). The mean procedural time was 123 ± 48.8 min, mean contrast volume was 359.03 ± 151.9 ml, and mean radiation dose was 9.4 ± 4.2 Gy. The mean number of wires per patient was 2.69 ± 1.32, and the most successful crossing strategy was antegrade wiring (56.3%). The commonest cause of failure was failure of re-entry (46.7%). One patient had peri-procedural MI (1.6%), and one patient required urgent CABG. There was no in-hospital mortality or cerebrovascular stroke. The cost ranged from 6520 Egyptian Pounds (EP) ($415) to 63,720 EP ($4058), with a mean of 26,213 EP ($1670). Conclusions Establishing a dedicated program for percutaneous coronary intervention for chronic total occlusion proved to be feasible and proficient, achieving high success rates with limited complications in view of limited resources, rationalized utilization of equipment, and limitation of hospital costs.

Dual antiplatelet therapy (DAPT) after percutaneous coronary intervention is necessary for preventing stent thrombosis and ensuring long-term cardiovascular protection. It is important to be thoughtful in balancing thrombotic and bleeding risk when deciding therapy regimen and duration. Revascularization randomized trials have studied many specific, at-risk populations; however, women remain underrepresented. Although there is evidence to support shortened DAPT duration in women, especially those at higher bleeding risk or on chronic oral anticoagulation, we need trials specifically enrolling and focusing on women.

The unexpected population increase in megacities has caused the urban heat island (UHI) effect. The Park Cooling Intensity (PCI) effect offers natural cooling from urban parks that can balance UHI. Doubling the urban population in the next two decades is expected to cause a rise in high-rise buildings. This research thoroughly evaluates the knowledge accumulated by adopting a Systematic Literature Review (SLR) since 2000 regarding the relationship between UHIs and PCI. To identify experimental trends, methodological trends, geographical interdependence, and research gaps in UHI mitigation, results obtained from 9 nations and 11 Köppen-Geiger climate zones are examined and compared from 55 selected research papers. Five significant topics are used to guide a thorough content analysis. The first section of the manuscript enlists identified factors of UHI mitigation affecting urban heat. The second section presents an observation table about how the different researchers have amalgamated the above-discussed factors to infer the comparison among the discussed literature. The study has identified three prominent research gaps explaining limitations in research: 1) current research trends, 2) governing factors of socio-economic and environmental aspects, and 3) exploration of evapotranspiration rates in terms of Bowen ratio. This review will aid researchers in selecting coping mechanisms for urban climates of extreme heat. [ABSTRACT FROM AUTHOR]

Importance: Ischemic heart disease is the leading cause of death worldwide. In ST-elevation myocardial infarction (STEMI), delaying reperfusion from the onset of chest pain increases the incidence of mortality and morbidity. Prehospital thrombolysis (PHT) has been evaluated in the setting of STEMI. We performed a systematic analysis of studies of PHT in acute STEMI. Objective: The objective of this study was to evaluate the all-cause mortality benefit in STEMI with PHT during short-term and long-term follow-up. Data Sources: In December 2020, the Cochrane search strategy was used to analyze randomized control trials, nonrandomized control studies, and registry studies in PubMed, EMBASE, Cochrane Library, Google Scholar, ClinicalKey, and Clinical Trial Registries. The search was repeated, and the included studies were updated in June 2023 to include more recent literature. We restricted the analysis to full-text publications in English. Study Selection: Studies using any thrombolytic agent in treating acute myocardial infarction in prehospital and inhospital settings with or without percutaneous Coronary intervention (PCI) were included in the analysis. Selection criteria included patient history and symptoms, electrocardiogram findings, and cardiac markers. Data Extraction: We used the Cochrane Handbook for Systematic Reviews of Interventions for assessing bias, the PRISMA flow diagram to show the process of inclusion and exclusion of studies, and RevMan software to perform meta-analysis. Main Outcomes and Measures: Outcomes include all-cause hospital mortality rate of PHT versus inhospital thrombolysis (IHT), influence of ischemic median time on all-cause mortality with PHT, and effect of PHT before PCI. The measures must have been observed for a follow-up period of up to 35 days, 1-year, and 5-years. Results: Data from 63,814 patients from 32 studies were reviewed. Results indicate a reduction in all-cause mortality in patients assigned to PHT (odds ratio [OR] −0.68, P < 0.00001) compared to IHT. There was a significant reduction in mortality when thrombolytics were administered before PCI (OR − 0.78, P = 0.0001). The overall survival was better with an ischemic time of

Although CR is cost-effective and reduces mortality and readmission rates, and many patients with acute myocardial infarction (AMI) after percutaneous coronary intervention (PCI) do not adhere to CR. This review aimed to synthesize the evidence on adherence to CR in patients with AMI after PCI (AMI-PCI).Patients and Methods: The review was conducted using the methodology proposed by the Joanna Briggs Institute (JBI) to guide reviews and reporting using the Preferred Reporting Items for Systematic Reviews and Meta-analyses Extended for Scoping Reviews (PRISMA-ScR). We searched PubMed, Web of Science, CINAHL, Embase, Ovid, and Scopus databases, and two reviewers independently screened the abstracts and full texts of eligible studies against the inclusion and exclusion criteria. Disagreements were resolved in consultation with a third reviewer.Results: A total of 10 studies were included in the analysis. The results demonstrated that CR reduces the incidence of complications and improves the quality of life of patients with AMI-PCI. However, the CR adherence rate was low, and the factors affecting it are complex and varied, including age, sex, and employment status. Furthermore, interventions to improve adherence in patients with AMI-PCI mainly combined the internet-based interventions, including videoconferencing tele-training, with wearable device monitoring and intelligent management platform follow-up. All these interventions have shown promising results compared with routine care.Conclusion: Adherence to CR in patients with AMI-PCI is generally low, and CR adherence is affected by many factors; however, relevant research designs are rare and simple. Healthcare professionals should pay more attention to adherence to CR in this population and use a variety of interventions to improve it.Keywords: cardiac rehabilitation, adherence, acute myocardial infarction, PCI, scoping review

Abstract Background Acute coronary syndrome (ACS) is a serious cardiovascular disease that severely affects the quality of life and longevity of patients. MicroRNAs (miRNAs) play a key role in the progression of ACS with significant clinical value. The aim of this study was to examine the clinical value of miR-223-5p in ACS and on the occurrence of major adverse cardiovascular events (MACE) after percutaneous coronary intervention (PCI). Methods The plasma expression of miR-223-5p was detected by RT-qPCR. The correlation of miR-223-5p and cTnI or Gensini score was shown by the Pearson method. Risk factors for the development of ACS were analyzed by multivariate logistic regression. The efficacy of miR-223-5p in identifying patients with ACS was shown by ROC curve. The predictive value of miR-223-5p for MACE development in ACS patients within 6 months after PCI was assessed by Kaplan-Meier curve and multivariate Cox regression. Results miR-223-5p levels were markedly elevated in ACS patients. miR-223-5p was found to be positively related to cTnI or Gensini score. miR-223-5p was a risk factor for ACS and significantly identified patients with ACS. MACE was more likely to occur after PCI in patients with high miR-223-5p levels, and miR-223-5p was an independent prognostic indicator of MACE. Conclusions miR-223-5p had diagnostic value for ACS and predicted MACE after PCI.

Furthermore, the impact of interobserver variability of coronary lesions on clinical decision-making was assessed. One of our motivations to do this research was the research gaps and our aim to have up-to-date information regarding interobserver variability among different cardiologists.Methods: Our objective was to quantify interobserver variability among cardiologists who have seen angiograms independently. Disagreement among cardiologists in the visual assessment of invasive coronary angiography of coronary artery stenosis is not uncommon in previous studies. Three cardiologists with extensive experience in coronary angiography, including the primary cardiologist of each patient, read the angiograms of 200 patients from Toronto General Hospital independently.Results: Our research showed the mean agreement among all participating observers was 77.4%; therefore, the interobserver variability of coronary angiography interpretation was 22.6%.Discussion: Coronary angiography is still the gold-standard technique for guidance regarding coronary lesions. Sometimes, coronary angiography results in underestimation or overestimation of a lesion’s functional severity. Interobserver variability should also be considered when interpreting the severity of coronary stenoses via invasive coronary angiography. This research shows that interobserver variability regarding coronary angiograms is still present (22.6%).Plain language summary:The gold-standard method for diagnosing coronary stenosis, invasive coronary angiography has some challenges too. One of these challenges has been the difference among various cardiologists regarding determination of severity of each coronary stenosis. In this study, we focused on differences in interobserver variability in coronary angiography interpretation. Three cardiologists who were experienced in coronary angiography read each patient’s coronary angiogram separately. Overall, 200 patients with a history of angiography at Toronto General Hospital were selected randomly. The research showed that overall agreement among all participating cardiologists with regard to the reading of coronary angiograms was 77.4%. In other words, interobserver variability of 22.6% was seen among the readers.Keywords: coronary angiography, ICA, PCI, fractional flow reserve, interobserver variability

Abstract Purpose Platelets play an important role in the pathogenesis of acute coronary syndrome (ACS), and adequate platelet inhibition is a cornerstone during invasive management with percutaneous coronary intervention (PCI). Despite this, pivotal role routine measurement of platelet function is not done. We aimed at using the using the Sonoclot device for measuring platelet activity and predicting outcome in patients with ACS undergoing PCI. Methods This was a cohort longitudinal study involving 50 patients who were admitted with ACS and undergoing emergent PCI in the critical care department at Cairo University from November 2020 to July 2021. Three parameters will be obtained: platelet function, ACT, and coagulation rate. Results According to the 1st parameter (platelet function), adequate platelet inhibition was achieved in 54% of our cases. To study the impact of this analysis, our population was classified into 2 groups (well-inhibited platelets vs. poorly inhibited platelets). The 2nd and 3rd parameters (ACT, CR) could separate our patients into 2 groups according to whether patients were well anticoagulated or not. Classification 1, well vs. poorly inhibited platelets, both groups were comparable. However, epicardial coronary flow (TIMI flow) and myocardial blush grade post-stenting were better in the well-inhibited platelets group. Classification 2, well vs. poor anticoagulation, there were no significant differences between the 2 groups. Conclusion Adequate platelet inhibition as measured by Sonoclot device can predict better outcomes in patients with ACS undergoing PCI.

Abstract Background Acute coronary syndrome (ACS) is one of the common causes of cardiovascular death. The related lncRNAs were novel approaches for early diagnosis and intervention. This paper focused on the clinical function of SNHG7 for patients after PCI. Methods The expression of SNHG7 was assessed in ACS patients. The predictive roles of SNHG7 were unveiled by the ROC curve. The relationship between SNHG7 and Gensini scores was judged by Pearson analysis. One-year follow-up was conducted and all patients were catalogued into different groups based on the prognosis. The qRT-PCR, K-M curve, and Cox regression analysis were performed to document the prognostic significance of SNHG7. Results SNHG7 was highly expressed in ACS and its three subtypes. SNHG7 showed a certain value in predicting ACS, UA, NSTEMI, and STEMI. Gensini is a closely correlated indicator of SNHG7. The declined expression of SNHG7 was observed in the non-MACE and survival groups. The risk of MACE and death was increased in the group with high expression of SNHG7. SNHG7 was an independent biomarker in patients with ACS after PCI. Conclusions SNHG7 might be a diagnostic and prognostic tool for ACS patients.

However, the predictive value of TyG-BMI in the prognosis of acute myocardial infarction (AMI) remains unclear.Methods: In total, 408 AMI patients who underwent PCI were consecutively included in this study. All included patients were then divided into three groups according to tertiles of TyG-BMI. The association between TyG-BMI and major adverse cardiovascular and cerebrovascular events (MACCEs) were investigated.Results: Participants were divided into three groups: tertile 1(≤ 199.4, n=136), tertile 2 (199.4– 231.8, n=136), and tertile 3 (≥ 231.8, n=136). Eighty (19.6%) patients had MACCEs: 18 (13.2%) in tertile 1, 26 (19.1%) in tertile 2, and 36 (25.7%) in tertile 3. The incidence of MACCEs increased as the tertiles of TyG-BMI increased (p< 0.05). Multivariate Cox regression analysis revealed that diabetes mellitus and TyG-BMI were independent predictors of MACCEs in AMI patients after PCI (p< 0.05). The receiver operating characteristic (ROC) curve showed that when TyG-BMI was ≥ 192.4, the sensitivity and specificity were 60.1% and 65.4%, respectively, and the area under the ROC curve (AUC) was 0.632 (95% confidence interval [CI]: 0.562– 0.703; p < 0.001).Conclusion: Elevated TyG-BMI level was an independent predictor of the composite MACCEs in patients with AMI after PCI.Keywords: triglyceride glucose body mass index, major adverse cardiac and cerebrovascular event, acute myocardial infarction, PCI

Abstract Background The efficacy of optimal medical therapy (OMT) with or without revascularization therapy in patients with stable coronary artery disease (SCAD) remains controversial. We performed a meta-analysis of randomized controlled trials (RCTs) that compared OMT with or without revascularization therapy for SCAD patients. Methods Studies were searched in PubMed, EMBASE, and the Cochrane Central Register of Clinical Trials from January 1, 2005, to December 30, 2023. The main efficacy outcome was a composite of all-cause death, myocadiac infarction, revascularization, and cerebrovascular accident. Results were pooled using random effects model and fixed effects model and are presented as odd ratios (ORs) with 95% confidence intervals (CI). Results Ten studies involving 12,790 participants were included. The arm of OMT with revascularization compared with OMT alone was associated with decreased risks for MACCE (OR 0.55 [95% CI 0.38–0.80], I²=93%, P = 0.002), CV death (OR 0.84 [95% CI 0.73–0.97], I²=36%, P = 0.02), revascularization (OR 0.32 [95% CI 0.20–0.50], I²=92%, P

Although exercise intervention is the most commonly used method to reverse and alleviate frailty, its application is restricted in patients with acute myocardial infarction following PCI due to cardiovascular instability and autonomic imbalance. Consequently, there is a need for a new practical intervention to address frailty syndrome in these patients.Purpose: This study aimed to investigate the effect of neuromuscular electrical stimulation in frail older AMI patients post-PCI.Patients and Methods: A single-blind, randomized controlled trial was carried out in the Department of Cardiovascular Medicine from March to October 2023. A total of 100 eligible participants were randomly divided into two groups: experimental (n = 50) and control (n = 50) groups, respectively. Both groups received usual care. The experimental group underwent neuromuscular electrical stimulation (NMES) on bilateral quadriceps and gastrocnemius muscles for 30 minutes daily from day 1 to day 7 after surgery. The primary outcomes measured included the frailty score, lower limb muscle strength, and lower limb muscle quality. Secondary outcomes included the activities of daily living score, inflammatory markers, and length of hospital stay. All participants were included in an intention-to-treat analysis after the study ended.Results: The frailty scores of the two groups exhibited a gradual decrease over time, and the scores of the experimental group were lower than those of the control group at 4 and 7 days after surgery (P< 0.001). Concurrently, the lower limb muscle strength showed an increasing trend over the time in the experimental group and a decreasing trend in the control group, and the scores of the experimental group surpassed those of the control group (p< 0.001). Moreover, a statistical difference was observed in the lower limb muscle mass across the groups after 7 days postoperatively compared with baseline on both sides (p< 0.05).Conclusion: Neuromuscular electrical stimulation has the potential to enhance lower limb function and alleviate frailty in elderly patients with acute myocardial infarction after PCI. These findings introduce a novel intervention approach for frailty management in the elderly population.Keywords: acute myocardial infarction, older, frailty, neuromuscular electrical stimulation, PCI

Abstract Background Stent restenosis is a relatively common phenomenon among patients with coronary heart disease undergoing percutaneous coronary intervention (PCI). It seems that a set of clinical, laboratory, and even genetic factors make people susceptible to such a phenomenon and in fact, this is multi-factorial. We aimed to first determine the underlying clinical and laboratory risk factors for the occurrence of stent re-stenosis after PCI based on a systematic review study, and after that, through a bioinformatics study, to evaluate the related genes and microRNAs with the occurrence of stent re-stenosis. Main text In the first step, the manuscript databases including Medline, Web of Knowledge, Google Scholar, Scopus, and Cochrane were deeply searched by the two blinded investigators for all eligible studies based on the considered keywords to introduce clinical and laboratory determinants of stent re-stenosis. In the bioinformatic phase, and following a review of the literature to identify genes and microRNAs involved in restenosis, the interaction of each gene with other genes associated with stent re-stenosis was determined by GeneMANIA network analysis and Cytoscape software. Overall, 67 articles (including 40,789 patients) on clinical and biochemical predictors for stent restenosis and 25 articles on genetic determinants of this event were eligible for the final analysis. The predictors for this event were categorized into four subgroups patient-based parameters including traditional cardiovascular risk profiles, stent-based parameters including type and diametric characteristics of the stents used, coronary lesion-based parameters including several two target lesions and coronary involvement severity and laboratory-based parameters particularly related to activation of inflammatory processes. In the bioinformatic phase, we uncovered 42 genes that have been described to be involved in such a phenomenon considering a special position for genes encoding inflammatory cytokines. Also, 12 microRNAs have been pointed to be involved in targeting genes involved in stent re-stenosis. Conclusions The incidence of stent re-stenosis will be the result of a complex interaction of clinical risk factors, laboratory factors mostly related to the activation of inflammatory processes, and a complex network of gene-to-gene interactions.

Abstract To investigate the factors that influence readmissions in patients with acute non-ST elevation myocardial infarction (NSTEMI) after percutaneous coronary intervention (PCI) by using multiple machine learning (ML) methods to establish a predictive model. In this study, 1576 NSTEMI patients who were hospitalized at the Affiliated Hospital of North Sichuan Medical College were selected as the research subjects. They were divided into two groups: the readmitted group and the non-readmitted group. The division was based on whether the patients experienced complications or another incident of myocardial infarction within one year after undergoing PCI. Common variables selected by univariate and multivariate logistic regression, LASSO regression, and random forest were used as independent influencing factors for NSTEMI patients’ readmissions after PCI. Six different ML models were constructed using these common variables. The area under the ROC curve, accuracy, sensitivity, and specificity were used to evaluate the performance of the six ML models. Finally, the optimal model was selected, and a nomogram was created to visually represent its clinical effectiveness. Three different methods were used to select seven representative common variables. These variables were then utilized to construct six different ML models, which were subsequently compared. The findings indicated that the LR model exhibited the most optimal performance in terms of AUC, accuracy, sensitivity, and specificity. The outcome, admission mode (walking and non-walking), communication ability, CRP, TC, HDL, and LDL were identified as independent predicators of readmissions in NSTEMI patients after PCI. The prediction model constructed by the LR algorithm was the best. The established column graph model established proved to be effective in identifying high-risk groups with high accuracy and differentiation. It holds a specific predictive value for the occurrence of readmissions after direct PCI in NSTEMI patients.

Background: Percutaneous coronary intervention (PCI), also known as coronary angioplasty, is the preferred strategy for treating obstructive coronary artery disease. Existing literature suggests the worsening of clinical outcomes in patients with previous coronary artery bypass grafting (CABG) history. In light of this, a comprehensive systematic review and meta-analysis was performed. Methods: Databases including PubMed, Cochrane Library, and ScienceDirect were utilized for the inclusive systematic search dating from inception to September 01, 2023. The risk of bias assessment was performed using the Newcastle-Ottawa scale for cohort studies, and the Cochrane Risk of Bias Tool for randomized controlled trials. Results: Ultimately, there were 16 eligible studies pooled together, involving a total of 250 684 patients, including 231 552 CABG-naïve patients, and 19 132 patients with a prior history of CABG. Overall, patients with CABG history were associated with significantly greater short-term mortality (P =.004), long-term mortality (P =.005), myocardial infarction (P <.00001), major adverse cardiovascular events (P =.0001), and procedural perforation (P <.00001). Contrastingly, CABG-naïve patients were associated with significantly greater risk of cardiac tamponade (P =.02) and repeat CABG (P =.03). No significant differences in stroke, bleeding, revascularization, or repeat PCI were observed. Conclusion: Comparatively worsened clinical outcomes were observed, as patients with prior CABG history typically exhibit complex coronary anatomy, and have higher rates of comorbidities in comparison to their CABG-naïve counterparts. The refinement of current procedural and surgical techniques, in conjunction with continued research endeavors, are needed in order to effectively address this trend. [ABSTRACT FROM AUTHOR]

Improved expertise and technological advancements have enabled the safe and effective performance of complex and high-risk-indicated percutaneous coronary intervention (CHIP) in patients previously considered inoperable or high-risk. Mechanical circulatory support (MCS) devices play a crucial role in stabilizing hemodynamics during percutaneous coronary intervention (PCI) -related ischemia, thereby reducing the risk of major adverse events and achieving a more complete revascularization. However, the use of MCS devices in protected PCI is not without risks, including peri-procedural myocardial infarction (MI), bleeding, and access-related complications. Despite numerous observational studies, there is a significant lack of randomized clinical trials comparing different MCS devices in various CHIP scenarios and evaluating their long-term safety and efficacy profiles. This review aims to summarize the current evidence regarding the benefits of MCS devices during CHIPs, offer a practical guide for selecting appropriate devices based on clinical scenarios, and highlight the unanswered questions that future trials need to address.

Background: The diet and physical activity of the world's population determine the increase in the number of bariatric surgeries. The most common types of bariatric surgery are laparoscopic sleeve gastrectomy (LSG) and Roux-Y gastric bypass (RYGB). Surgical interventions are carried out in patients with numerous comorbidities, among which the most common are cardiovascular diseases. The aim of the present study was to review the literature regarding the safety and results of surgical treatment in patients with cardiac revascularization prior to surgery. Methods: We performed an online search in Pubmed in September 2023 to identify articles that reported cardiac revascularization prior to bariatric surgery. The extracted information included details of the working method, number of patients, types of cardiovascular disease—heart failure (HF) and cardiac artery disease (CAD), types of revascularization—coronary artery bypass graft (CABG), percutaneous coronary intervention (PCI) or both CABG + PCI, demographic data (age, gender, race), clinical characteristics (body mass index—BMI, smoking status), comorbidities (diabetes mellitus, hypertension, prior myocardial infarction), postoperative complications, and postoperative results. Results: A total of 171 records were identified by the initial search, and 165 papers were excluded after applying the exclusion criteria (types of cardiovascular disease, types of revascularization, and demographic data). We evaluated a group of 9479 patients of which 730 had HF, 2621 CAD, and 1426 underwent prior cardiac revascularization. The analysis of the demographic data showed an average age of 55.5 years and a fluctuation of the male gender between 39% and 71.1%, and the female gender between 28.9% and 61%. The main types of bariatric interventions were RYGB (3659 cases) and LSG (659 cases), to which adjustable gastric band (AGB) and bilio-pancreatic diversion—duodenal switch (BPD-DS) were added. Among the most postprocedural complications were ST-segment elevation myocardial infarction (2 patients), gastro-intestinal bleeding (51 cases), pulmonary embolism (1 patient), arrhythmia (3 patients) and pacemaker insertion (1 patient). The recorded postoperative mortality rate was 0.42% (6 cases). Conclusions: Bariatric surgery remains safe in patients with cardiac revascularization. These finding need to be confirmed in more large-scale randomized trials. [ABSTRACT FROM AUTHOR]

Conclusions: miR-223-5p had diagnostic value for ACS and predicted MACE after PCI. [ABSTRACT FROM AUTHOR]

Objective Exploring the predictive value of blood lipid variability for adverse cardiovascular events in patients with acute ST segment elevation myocardial infarction (STEMI) after emergency percutaneous coronary intervention (PCI). Methods A total of 235 STEMI patients who underwent emergency PCI in our hospital from October 2020 to October 2022 were selected as the research objects. According to whether target lesion failure (TLF) occurred, the patients were divided into TLF group and control group Lipid variability [standard deviation (SD), coefficient of variation (CV) and mean-independent coefficient of variation (VIM)] of the two groups were compared. Multivariate Cox regression analysis was used to explore the related factors of TLF in STEMI patients after emergency PCI, and receiver operating characteristic curve (ROC) was used to analyze the predictive value. Results Variability indexes of low-density lipoprotein (LDL), high-density lipoprotein (HDL) and lipoprotein a [LP(a)] in TLF group: LDL (SD), LDL (CV), LDL (VIM), HDL (SD), HDL (CV), HDL (VIM), LP(a) (SD), LP(a) (CV), LP(a) (CV) a) (VIM) were higher than those in control group, and the differences were statistically significant (P < 0.05). The results of multivariate Cox regression analysis showed that LDL (SD), LDL (CV), LDL (VIM), HDL (SD), HDL (CV), HDL (VIM), LP(a) (SD), LP(a) (CV), LP (a) (VIM) were all risk factors for TLF in STEMI patients after emergency PCI (P < 0.05). ROC curve analysis results showed that, LDL (SD), LDL (CV), LDL (VIM), HDL (SD), HDL (CV), HDL (VIM), LP(a) (SD), LP(a) (CV), LP(a) (VIM) have certain predictive value for TLF in STEMI patients after emergency PCI(AUC: 0.790, 0.805, 0.833, 0.766, 0.795, 0.816, 0.773, 0.782, 0.798). Conclusion Lipid variability is associated with adverse cardiovascular events in STEMI patients after emergency PCI, and is an independent risk factor for TLF in STEMI patients after emergency PCI.

The suitability of CABG compared to PCI for patients with coronary artery disease (CAD) remains a controversial issue. Despite growing evidence supporting the clinical efficacy of these revascularization strategies, there is little evidence regarding their long-term cost)effectiveness. The aim of this study was to critically evaluate the literature regarding the cost-effectiveness of CABG compared to PCI and assess the quality of the available economic evidence.The methods is a systematic review was conducted using three databases: PubMed, Scopus and Google Scholar. Three studies were retrieved then compared the economic evaluation of CABG vs PCI measures The result is the improvement (ICER) reported across studies varied widely by perspective and timeframe. ICER calculation was reported to be favorable and cost effective for CABG. The conclusions is CABG is more cost-effective than PCI in cases of coronary artery disease. The evidence supporting this cost-effectiveness will continue to evolve and further evaluation over a period of 10 years or more is needed considering societal perspectives. [ABSTRACT FROM AUTHOR]

Background: Due to its high resolution, optical coherence tomography (OCT) is the most suitable modality for neointimal coverage assessments. Evaluation of stent healing seems crucial to accurately define their safety profile since delayed healing is connected with stent thrombosis. This study aimed to present an algorithm for automated quantitative analysis of stent strut coverage at the early stages of vessel healing in intravascular OCT. Methods: A set of 592 OCT frames from 24 patients one month following drug-eluting stent implantation was used to assess the algorithm's effectiveness. Struts not covered on any side or covered but only on one side were categorized as uncovered. The algorithm consists of several key steps: preprocessing, vessel lumen segmentation, automatic strut detection, and measurement of neointimal thickness. Results: The proposed algorithm proved its efficiency in lumen and stent area estimation versus manual reference. It showed a high positive predictive value (PPV) (89.7%) and true positive rate (TPR) (91.4%) in detecting struts. A qualitative assessment for covered and uncovered struts was characterized by high TPR (99.1% and 80%, respectively, for uncovered and covered struts) and PPV (77.3% and 87%). Conclusions: The proposed algorithm demonstrated good agreement with manual measurements. Automating the stent coverage assessment might facilitate imaging analysis, which might be beneficial in experimental and clinical settings. [ABSTRACT FROM AUTHOR]

Acute coronary syndrome (ACS) admissions and percutaneous coronary intervention (PCI) volume declined during periods of COVID-19 lockdown internationally in 2020. The effect of lockdown on emergency medical service (EMS) utilisation, and PCI volume during the initial phase of the pandemic in Australia has not been well described. We analysed data from the Victorian Cardiac Outcomes Registry (VCOR), a state-wide PCI registry, linked with the Ambulance Victoria EMS registry. PCI volume, 30-day major adverse cardiovascular and cerebrovascular events (MACCE; composite of mortality, myocardial infarction, stent thrombosis, unplanned revascularisation, and stroke), and EMS utilisation were compared over four time periods: lockdown (26 Mar 2020–12 May 2020); pre-lockdown (26 Feb 2020–25 Mar 2020); post-lockdown (13 May 2020–10 Jul 2020); and the year prior (26 Mar 2019–12 May 2019). Interrupted time series analysis was performed to assess PCI trends within and between consecutive periods. The EMS utilisation for ACS during lockdown was higher compared with other periods: lockdown 39.4% vs pre-lockdown 29.7%; vs post-lockdown 33.6%; vs year prior 27.1%; all p<0.01. Median daily PCI cases were similar: 31 (IQR 10, 38) during lockdown; 39 (15, 49) pre-lockdown; 39.5 (11, 44) post-lockdown; and, 42 (10, 49) the year prior; all p>0.05. Median door-to-procedure time for ACS indication during lockdown was shorter at 3 hours (1.2, 20.6) vs pre-lockdown 3.9 (1.7, 21); vs post-lockdown 3.5 (1.5, 21.26); and, the year prior 3.5 (1.5, 23.7); all p<0.05. Lockdown period was associated with lower odds for 30-day MACCE compared to pre-lockdown (odds ratio [OR] 0.55 [0.33–0.93]; p=0.026); post-lockdown (OR 0.66; [0.40–1.06]; p=0.087); and the year prior (OR 0.55 [0.33–0.93]; p=0.026). Contrary to international trends, EMS utilisation for ACS increased during lockdown but PCI volumes remained similar throughout the initial stages of the pandemic in Victoria, with no observed adverse effect on 30-day MACCE during lockdown. These data suggest that the public health response in Victoria was not associated with poorer quality cardiovascular care in patients receiving PCI. [ABSTRACT FROM AUTHOR]

The optimal management strategy for significant unprotected ostial left anterior descending artery (LAD) disease remains undefined. Merits of the two most common percutaneous approaches are considered in this quantitative synthesis. A meta-analysis was performed to compare ostial stenting (OS) and crossover stenting (CS) in the treatment of unprotected ostial LAD stenosis. The primary outcome is the disparity in target lesion revascularisation (TLR). The Mantel-Haenszel method was employed with random effect model, chosen a priori to account for heterogeneity among the included studies. Seven studies comprising 1,181 patients were included in the analyses. Of these, 482 (40.8%) patients underwent CS. Overall, there was a statistically significant trend in favour of CS (odds ratio 0.51, 95% confidence interval 0.30–0.86, p=0.01) with respect to the rate of TLR at follow-up. This remained true when TLR involving the left circumflex artery (LCx) was considered, even when there was a greater need for unintended intervention to the LCx during the index procedure (odds ratio 6.68, 95% confidence interval: 1.69–26.49, p=0.007). Final kissing balloon inflation may reduce the need for acute LCx intervention. Imaging guidance appeared to improve clinical outcomes irrespective of approach chosen. In the percutaneous management of unprotected ostial LAD disease, CS into the left main coronary artery (LMCA) appeared to reduce future TLR. Integration of intracoronary imaging was pivotal to procedural success. The higher incidence of unintended LCx intervention in the CS arm may be mitigated by routine final kissing balloon inflation, although the long-term implication of this remains unclear. In the absence of randomised trials, clinicians' discretion remains critical. [ABSTRACT FROM AUTHOR]

Background Anomalous coronary arteries originating from the contralateral sinus of Valsalva constitute a rare congenital anomaly. Most of such anomalous coronary arteries exhibit slit-like orifice that are often compounded by external compressive factors. Consequently, percutaneous coronary intervention (PCI) of these vessels poses considerable challenges, both in terms of cannulation but also intervention in often acutely angulated vessels. Case summary A 61-year-old man, with a history of previous coronary artery bypass graft surgery and PCI presented with a history consistent with unstable angina. Notably, the left circumflex artery (LCX) in this individual exhibited an anomalous origin. Due to unfavourable anatomy and ambiguous LCX ostium take-off, previous operators had elected PCI of the saphenous vein graft (SVG) anastomosed to the obtuse marginal branch. A computed tomography scan on this occasion confirmed occlusion of the SVG and defined precise origin of anomalous coronary artery. Real-time live intravascular ultrasound (IVUS) positioned in the ascending aorta, in the right sinus of Valsalva, allowed visualization of the origin and wiring of the anomalous circumflex coronary artery and also facilitated successful PCI. Discussion As far as we are aware, this is the first description of IVUS assisted wiring of an anomalous coronary artery. Intravascular ultrasound also facilitated decision making in this complex angioplasty of an angulated and heavily diseased circumflex coronary artery. [ABSTRACT FROM AUTHOR]

Background Entrapment and fracture of the coronary guidewire are rare but major complications of percutaneous coronary intervention (PCI). The incidence of these complications is reported to be <1%. Case summary A 52-year-old male patient with diabetes and dyslipidaemia presented with posterior wall myocardial infarction. An angiogram revealed occlusion in the left circumflex (LCX) artery. Attempts to pass a guidewire through the lesion led to its entrapment and eventual fracture. Several techniques and manoeuvres failed to retrieve the fractured guidewire, which remained lodged in the LCX. An endovascular snare catheter also proved unsuccessful. The fragment was eventually removed using the triple-wire technique, although this caused coronary perforation and dissection. The perforation was identified and stented. A subsequent stent addressed a dissection in the left main/left ascending artery area, likely caused by the coronary snare. These interventions were crucial in stabilizing the patient's condition, leading to recovery with a left ventricular ejection fraction of 50% and a viable LCX artery. The patient exhibited an uneventful progression at the 1-year follow-up. Discussion Coronary guidewire fracture during PCI is a rare event often associated with coronary calcifications. Percutaneous removal remains the mainstay treatment for fragment removal; however, it carries risks. The triple-wire technique, a newer method that entangles and extracts the fractured guidewire without specialized equipment, was effective in removing the fragmented guidewire. If asymptomatic, leaving the wire in situ is documented as a favourable approach. This case highlights that the triple-wire technique can effectively be used for the extraction of fractured guidewire fragments from the coronary vessels. [ABSTRACT FROM AUTHOR]

Background Approximately 5–15% of patients with acute coronary syndrome have myocardial infarction with unobstructed coronary arteries (MINOCA). Guidelines recommend invasive assessments to identify underlying causes for MINOCA such as coronary artery spasm (CAS), spontaneous coronary dissection, or microvascular disease as well as non-invasive assessments in search of myocarditis, takotsubo syndrome, or cardiomyopathies. Case summary A 54-year-old male patient presented with ST-segment elevation myocardial infarction (STEMI). Upon arrival, ST-segment elevation and symptoms had ceased. Emergency coronary angiography showed diffuse epicardial atherosclerosis with stenoses in the distal left anterior descending coronary artery (LAD) and second diagonal branch (D2); however, no epicardial occlusion was seen. Left ventriculography showed no clear wall motion abnormalities. Based on these findings, intracoronary acetylcholine (ACh) testing in search of CAS was performed. At 200 µg ACh intracoronary ST-segment elevation and chest pain recurred. Angiography showed occlusive epicardial spasm in the LAD and D2. Based on studies where the tendency of epicardial CAS was linked with the presence of epicardial atherosclerosis, the decision was made to perform PCI in the LAD and D2. ACh re-challenge after intracoronary nitroglycerine revealed only very mild symptoms, no demonstrable epicardial CAS, and no ST-segment elevation anymore. Cardiac enzymes reached their peak on day one [creatine kinase max 262 U/L (norm < 190 U/L), maximum of high-sensitivity troponin T 269 pg/mL (n < 14 pg/mL)]. Discussion There is a broad spectrum of patients with STEMI without culprit lesion regarding the extent of epicardial disease. In cases with an unclear culprit lesion, other causes for the acute presentation such as CAS should be investigated in an ad hoc fashion. The interplay of epicardial atherosclerosis and CAS should receive more attention in future trials. [ABSTRACT FROM AUTHOR]

Engaging intracoronary imaging (IC) techniques such as intravascular ultrasound or optical coherence tomography enables the precise description of vessel architecture. These imaging modalities have well-established roles in providing guidance and optimizing percutaneous coronary intervention (PCI) outcomes. Furthermore, IC is increasingly recognized for its diagnostic capabilities, as it has the unique capacity to reveal vessel wall characteristics that may not be apparent through angiography alone. This manuscript thoroughly reviews the contemporary landscape of IC in clinical practice. Focused on current methodologies, the review explores the utility and advancements in IC techniques. Emphasizing their role in clarifying coronary pathophysiology, guiding PCI, and optimizing patient outcomes, the manuscript critically evaluates the strengths and limitations of each modality. Additionally, the integration of IC into routine clinical workflows and its impact on decision-making processes are discussed. By synthesizing the latest evidence, this review provides valuable insights for clinicians, researchers, and healthcare professionals involved in the dynamic field of interventional cardiology.

Background: The literature review shows that female patients are more frequently underdiagnosed or suffer from delayed diagnosis. Recognition of sex-related differences is crucial for implementing strategies to improve cardiovascular outcomes. We aimed to assess sex-related disparities in the frequency of fractional flow reserve (FFR)-guided procedures in patients who underwent angiography and/or percutaneous coronary intervention (PCI). Methods: We have derived the data from the national registry of percutaneous coronary interventions and retrospectively analyzed the data of more than 1.4 million angiography and/or PCI procedures [1,454,121 patients (62.54% men and 37.46% women)] between 2014 and 2022. The logistic regression analysis was conducted to explore whether female sex was associated with FFR utilization. Results: The FFR was performed in 61,305 (4.22%) patients and more frequently in men than women (4.15% vs. 3.45%, p < 0.001). FFR was more frequently assessed in females with acute coronary syndrome than males (27.75% vs. 26.08%, p < 0.001); however, women with chronic coronary syndrome had FFR performed less often than men (72.25% vs. 73.92%, p < 0.001). Females with FFR-guided procedures were older than men (69.07 (±8.87) vs. 65.45 (±9.38) p < 0.001); however. less often had a history of myocardial infarction (MI) (24.79% vs. 36.73%, p < 0.001), CABG (1.62% vs. 2.55%, p < 0.005) or PCI (36.6% vs. 24.79%, p < 0.001) compared to men. Crude comparison has shown that male sex was associated with a higher frequency of FFR assessment (OR = 1.2152–1.2361, p < 0.005). Conclusions: Despite a substantial rise in FFR utilization, adoption in women remains lower than in men. Female sex was found to be an independent negative predictor of FFR use.

In 2019, approximately 330 million individuals in China were affected by cardiovascular diseases, with 11.4 million cases specifically attributed to coronary artery disease (CAD). A national public health report indicated that the mortality rate for CAD ranged from 121.59 to 130.14 per 100,000 individuals in 2019. The treatments for CAD include lifestyle changes, medications, percutaneous coronary intervention (PCI) and coronary artery bypass grafting. To investigate the management effect of a digital health program in patients with coronary artery disease (CAD) after percutaneous coronary intervention (PCI). This retrospective study compares blood pressure, blood glucose, low-density lipoprotein cholesterol (LDL-C), medication adherence, lifestyle modification, and readmission rate between digital health users and traditional follow-up in post-PCI CAD patients. In this study of 698 CAD patients, the 6-month readmission rate of all patients was 27.4%, with digital health users showing lower rates than those in traditional follow-up (22.6% vs. 32.1%, p= 0.005). Digital health users had significantly higher target achievements rates in blood pressure (79.7% vs. 54.7%, p< 0.001), blood glucose (98.9% vs. 82.5%, p< 0.001) and LDL-C level (71.3% vs. 52.7%, p< 0.001) at 6-month post-PCI. The digital health group had more patients adopting lifestyle changes, including quitting smoking, maintaining a healthy diet, and exercising regularly. In risk factor analysis, digital health utilization (OR = 0.60, 95%CI: 0.40–0.90, p= 0.014) and multivessel disease (double: OR = 1.72, 95%CI: 1.09—2.72, p= 0.02; triple: OR = 2.59, 95%CI: 1.61–4.17, p< 0.001) were independent predictors of CAD-related cardiovascular readmissions. Post-PCI patients using digital health platforms exhibited improved blood pressure, glucose, and LDL-C control, greater treatment adherence, enhanced lifestyle changes, and reduced six-month readmission rates versus those with traditional follow-up.

Background: Coronary artery disease (CAD) is presently the foremost cause of mortality globally and is anticipated to rise in the near future. Coronary artery bypass grafting (CABG) and percutaneous coronary interventions (PCIs) serve as alternate revascularization strategies for individuals with multi-vessel CAD. Objective: To investigate whether previous history of PCI will affect morbidity and mortality outcomes in patients undergoing subsequent CABG or not, particularly if CABG was done within the first year after PCI. Patients and methods: Over a six-month period, 100 patients with multi-vessel CAD who underwent isolated on-pump CABG in Nasser National Institute, Beni-Suef University, and Fayoum University. Patients were excluded if they were undergoing off pump CABG, combined CABG with other procedures, redo CABG, had poor myocardial contractility and patients who had severe preoperative comorbidities. Mortality and morbidity outcomes were analyzed and included 30-day mortality, length of hospital stay, postoperative reopening for bleeding, perioperative myocardial infarction (MI), and prolonged ventilation and arrhythmias. Results: Total number of grafts in group A was higher than that of group B (3.16 ± 0.841 versus 2.64 ± 0.898 respectively), which was statistically significant (P value 0.003). The mean time of cardiopulmonary bypass (CPB) and aortic cross clamp time (ACC) were relatively higher in group B (87.6 ± 32.84 and 52.98 ±19 respectively) than in group A (87.38 ±27.29 and 50.38 ±19.70 respectively) despite lesser number of total grafts in group B, which may denote poor targets in this group. Total morbidity including; length of hospital stay, postoperative reopening for bleeding, perioperative MI, prolonged ventilation and arrhythmias were higher in group B and it was statistically significant (P value 0.009). Conclusion: Prior PCI may adversely affect the outcomes of later CABG in terms of morbidity and mortality if performed within one year before CABG. [ABSTRACT FROM AUTHOR]
