Contemporary data on the independent association of severe tricuspid regurgitation (TR) with excess mortality are needed. The aims of this study were to describe contemporary outcomes of patients with severe TR and to identify outcome modifiers.Consecutive echocardiographic reports linked to clinical data from the largest medical center in Israel (2007-2019) were reviewed. The primary outcome was all-cause mortality. Cox regression and propensity score matching models were applied.The final cohort included 97,096 patients. Mild, moderate, and severe TR was documented in 27,147 (28%), 2,844 (3%) and 1,805 (2%) patients, respectively. During a median follow-up period of 5 years (interquartile range, 2-8 years), 22,170 patients (23%) died. Kaplan-Meier survival analysis demonstrated an increased risk for death with an increasing degree of TR (log-rank P .001). Propensity score matching of 1,265 patients with severe TR and matched control subjects showed that compared with those with nonsevere TR, patients with severe TR were 17% more likely to die (95% CI, 1.05-1.29; P = .003). The association of severe TR with survival was dependent on estimated right ventricular (RV) pressure, with a more pronounced effect among patients with estimated systolic pressure ≤ 40 mm Hg (hazard ratio, 2.12 vs 1.04; P for interaction.001). A landmark subanalysis of 17,967 patients demonstrated that RV function deterioration on follow-up echocardiography modified the association of severe TR with survival. It was more significant among patients with preserved and stable RV function (P for interaction = .035).The outcome of severe TR is modified by RV pressure and function. Once RV function deteriorates, differences in the outcomes of patients with and without severe TR are less pronounced.

The professional practice of biomedical engineering can lead to severe consequences. These potential consequences do not differ from those expected in the exercise of the medical profession. Hence, the ethical framework of biomedical engineers (BMEs) should not differ substantially from the ethical framework of medical doctors (MDs). In medicine, an element that is perceived as symbolic but essential in the formation of the ethical conscience of MDs is the “Hippocratic Oath”. The “Hippocratic Oath”, or its modern adaptation, the “Physician's Pledge”, is a brief not legally binding solemn declaration of ethical commitments that medical students take as a rite of passage in their final year or just after graduation. In other healthcare professions, such as nursing or pharmacy, sometimes the “Hippocratic Oath” is also taken. However, in its different versions, the “Hippocratic Oath” contains aspects that would not apply to the field of biomedical engineering and, therefore, its adoption without adaptations would be inappropriate. We have drafted a “Biomedical Engineer’s Pledge” aiming at strengthening the ethical awareness of future biomedical engineers. It consists of a preamble sentence, ten promises, and a concluding sentence. Top priority is given to the first promise, which combines the fundamental principles of beneficence and non-maleficence.

Pulsed electric fields (PEFs) have emerged as an ideal cardiac ablation modality. At present numerous clinical trials in humans are exploring PEF as an ablation strategy for both atrial and ventricular arrhythmias, with early data showing significant promise. As this is a relatively new technology there is limited understanding of its principles and biophysics. Importantly, PEF biophysics and principles are starkly different to current energy modalities (radiofrequency and cryoballoon). Given the relatively novel nature of PEFs, this review aims to provide an understanding of the principles and biophysics of PEF ablation. The goal is to enhance academic research and ultimately enable optimization of ablation parameters to maximize procedure success and minimize risk.

OBJECTIVES Type 2 diabetes mellitus (DM) is a frequent comorbidity among patients suffering from advanced heart failure necessitating a left ventricular assist device (LVAD) implant. The goal of this study was to evaluate the impact of type 2 DM on early and long-term outcomes of patients following an LVAD implant. METHODS We performed an observational cohort study in a large tertiary care centre in Israel. All data of patients who underwent a continuous flow LVAD implant between 2006 and 2020 were extracted from our departmental database. Patients were divided into 2 groups: group I (patients without diabetes) and group II (patients with diabetes). We compared short-term (30-day and 3-month) mortality, intermediate-term (1- and 3-year) mortality and long-term (5 year) mortality between the 2 groups. RESULTS The study population included 154 patients. Group I (patients without diabetes) comprised 88 patients and group II (patients with diabetes) comprised 66 patients. The mean follow-up duration was 38.2 ± 30.3 months. Short- and intermediate-term mortality (30 days, 1 year and 3 years) was higher in the group with DM compared with the group without DM but did not reach any statistically significant difference: 16.1% vs 9.8% (P = 0.312), 24.2% vs 17.3% (P = 0.399) and 30.6% vs 21.9% (P = 0.127) respectively. Long-term 5-year mortality was significantly higher in the group with DM compared to the group without: 38.7% vs 24.4% (P = 0.038). Furthermore, predictors of long-term mortality included diabetes (hazard ratio 2.09, confidence interval 1.34–2.84, P = 0.004), as demonstrated by regression analysis. CONCLUSIONS Patients with diabetes and those without diabetes have similar 30-day and short- and intermediate-term mortality rates. The mortality risk of diabetic patients begins to increase 3 years after an LVAD implant. Diabetes is an independent predictor of long-term, 5-year mortality after an LVAD implant.

Background: Previous animal studies have shown no significant vascular injury from pulsed electrical field (PEF) ablation. We sought to assess the effect of PEF on swine coronary arteries. Methods: We performed intracoronary and epicardial (near the coronary artery) PEF ablations in swine pretreated with dual antiplatelet and antiarrhythmic therapy. Intracoronary PEF was delivered using MapiT catheters (Biotronik, Berlin), whereas epicardial PEF was delivered using EPT catheters (Boston Scientific, MA). PEF pulse duration was microseconds (Nanoknife 3.0, Angio Dynamics, NY) or nanoseconds (CellFX, Pulse Biosciences, CA). Results: We performed 39 intracoronary ablations in 10 swine and 20 epicardial-pericoronary ablations in 4 separate swine. Intracoronary PEF was delivered at higher energy compared with epicardial PEF (46 [interquartile range, IQR 20–85] J versus 10 [IQR 10–11] J, P < 0.01). Reversible coronary spasm occurred in 49% intracoronary ablations and 45% epicardial ablations ( P =0.80). At the end study, fixed coronary stenosis was demonstrated in 44% intracoronary ablations (80% for microsecond PEF and 18% for nanosecond PEF) and 0% epicardial ablations. Visible hemorrhagic and/or fibrotic myocardial lesions were observed at necropsy with similar frequency between intracoronary and epicardial PEF (45% versus 50%, P =0.70). Nanosecond PEF (49 ablations in 11 swine), when compared with microsecond PEF (10 intracoronary ablations in 3 swine), resulted in lower energy delivery (21 [IQR 10–46] J versus 129 [IQR 24–143] J, P =0.03) and less incidence of fixed coronary stenosis (18% versus 80%, P =0.04). Conclusions: In the swine model, intracoronary PEF resulted both in significant coronary spasm and fixed coronary stenosis. Epicardial PEF, delivered at lower energy, resulted in reversible spasm but no fixed coronary stenosis.

The treatment of choice for severe rheumatic mitral stenosis is balloon mitral valvuloplasty (BMV). Numerous predictors of immediate and long-term procedural success have been described. The aims of this study were to describe our experience with BMV over the last decade and to evaluate predictors of long-term event-free survival.Medical records were retrospectively analyzed of patients who underwent BMV between 2009 and 2021. The primary outcome was a composite endpoint of all-cause mortality, mitral valve replacement (MVR), and repeat BMV. Long-term event-free survival was estimated using the Kaplan-Meier curves. Logistic regression was used to create a multivariate model to assess pre-procedural predictors of the primary outcome.A total of 96 patients underwent BMV during the study period. The primary outcome occurred in 36 patients during 12-year follow-up: 1 (1%) patient underwent re-BMV, 28 (29%) had MVR, and 8 (8%) died. Overall event-free survival was 62% at 12 years. On multivariate analysis, pre-procedural left atrial volume index (LAVI)80 mL/m² had a significant independent influence on event-free survival, as did previous mitral valve procedure and systolic pulmonary arterial pressure above 50 mmHg.Despite being a relatively low-volume center, excellent short and long-term results were demonstrated, with event-free survival rates consistent with previous studies from high-volume centers. LAVI independently predicted long-term event-free survival.

Data de publicació electrónica: 30-09-2022 BACKGROUND: Pulsed field ablation (PFA) is a novel non-thermal cardiac ablation technology based on irreversible electroporation. Unfortunately, the characteristics of the electric field waveforms used in clinical and experimental PFA are not typically reported. This study examines the effect of the frequency of biphasic waveforms and compares biphasic to monophasic waveforms. METHODS: A total of 29 Sprague-Dawley rats were treated with PFA using an epicardial monopolar electrode. Biphasic waveforms with three different frequencies, 90, 260 and 450 kHz (10 bursts of 100 µs duration at 500 V or 800 V) and monophasic waveforms (10 pulses of 100 µs duration at 500 V) were studied. Collateral neuromuscular stimulation and temperature increase in the point of application were directly measured. Lesion formation was assessed 3 weeks after treatment by histopathologic analysis. Computer simulations were used to estimate the electric field lethal threshold for each condition. A previous in vitro study was performed to draw a complete characterization of the studied dependencies. RESULTS: Morphometric analysis demonstrated a significant association between chronic lesion size and waveform characteristics. For the same voltage level, monophasic waveforms yielded the largest lesions compared to any of the biphasic protocols (p

Aims This study evaluated the impact of serum uric acid (sUA) on the accuracy of pooled cohort equations (PCE) model, Systematic COronary Risk Evaluation 2 (SCORE2), and SCORE2-older persons. Methods and results We evaluated 19 769 asymptomatic self-referred adults aged 40–79 years free of cardiovascular disease and diabetes who were screened annually in a preventive healthcare setting. sUA levels were expressed as a continuous as well as a dichotomous variable (upper sex-specific tertiles defined as high sUA). The primary endpoint was the composite of death, acute coronary syndrome, or stroke, after excluding subjects diagnosed with metastatic cancer during follow-up. Mean age was 50 ± 8 years and 69% were men. During the median follow-up of 6 years, 1658 (8%) subjects reached the study endpoint. PCE, SCORE2, and high sUA were independently associated with the study endpoint in a multivariable model (P < 0.001 for all). Continuous net reclassification improvement analysis showed a 13% improvement in the accuracy of classification when high sUA was added to either PCE or SCORE2 model (P < 0.001 for both). sUA remained independently associated with the study endpoint among normal-weight subjects in the SCORE2 model (HR 1.3, 95% CI 1.1–1.6) but not among overweight individuals (P for interaction = 0.01). Subgroup analysis resulted in a significant 16–20% improvement in the model performance among normal-weight and low-risk subjects (P < 0.001 for PCE; P = 0.026 and P < 0.001 for SCORE2, respectively). Conclusion sUA significantly improves the classification accuracy of PCE and SCORE2 models. This effect is especially pronounced among normal-weight and low-risk subjects.

Patients with rapidly deteriorating clinical status due to severe aortic stenosis are often referred for expedited transcatheter aortic valve replacement (TAVR). Data regarding the outcome of such interventions is limited. We aimed to evaluate the outcome of patients undergoing expedited TAVR.Data were derived from the Israeli Multicenter Registry.Subjects were divided into two groups based on procedure urgency: patients who were electively hospitalized for the procedure (N = 3140) and those who had an expedited TAVR (N = 142). Procedural and periprocedural complication rates were significantly higher among patients with an expedited indication for TAVR compared to those having an elective procedure: valve malposition 4.6% versus 0.6% (p lt; 0.001), procedural cardiopulmonary resuscitation 4.3% versus 1.0% (p = 0.007), postprocedure myocardial infarction 2.0% versus 0.4% (p = 0.002), and stage 3 acute kidney injury 3.0% versus 1.1%, (p lt; 0.001). Patients with expedited indication for TAVR had significantly higher in hospital mortality (5.6% vs. 1.4%, p = 0.003). Kaplan-Meier's survival analysis showed that patients undergoing expedited TAVR had higher 3-year mortality rates compared to patients undergoing an elective TAVR procedure (p lt; 0.001). Multivariate analysis found that patients with expedited indication had fourfolds increased risk of in-hospital mortality (odds ratio: 4.07, p = 0.001), and nearly twofolds increased risk of mortality at 3-year (hazard ratio: 1.69, p = 0.001) compared to those having an elective procedure.Patients with expedited indications for TAVR suffer from poor short- and long-term outcomes. It is important to characterize and identify these patients before the deterioration to perform TAVR in a fast-track pathway to minimize their procedural risk.

Objective: To investigate the association of voice analysis with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. Patients and Methods: A vocal biomarker, a unitless scalar with a value between 0 and 1, was developed based on 434 voice samples. The biomarker training was followed by a prospective, multicenter, observational study. All subjects were tested for SARS-CoV-2, had their voice recorded to a smartphone application, and gave their informed consent to participate in the study. The association of SARS-CoV-2 infection with the vocal biomarker was evaluated. Results: The final study population included 80 subjects with a median age of 29 [range, 23 to 36] years, of whom 68% were men. Forty patients were positive for SARS-CoV-2. Infected patients were 12 times more likely to report at least one symptom (odds ratio, 11.8; P

Contains fulltext : 283507.pdf (Publisher’s version ) (Open Access) Background: Data to support the routine use of embolic protection devices for stroke prevention during transcatheter aortic valve replacement (TAVR) are controversial. Identifying patients at high risk for peri-procedural cerebrovascular events may facilitate effective patient selection for embolic protection devices during TAVR. Aim: To generate a risk score model for stratifying TAVR patients according to peri-procedural cerebrovascular events risk. Methods and results: A total of 8779 TAVR patients from 12 centers worldwide were included. Peri-procedural cerebrovascular events were defined as an ischemic stroke or a transient ischemic attack occurring ≤24 h from TAVR. The peri-procedural cerebrovascular events rate was 1.4% (n = 127), which was independently associated with 1-year mortality (hazards ratio (HR) 1.78, 95% confidence interval (CI) 1.06-2.98, p < 0.028). The TASK risk score parameters were history of stroke, use of a non-balloon expandable valve, chronic kidney disease, and peripheral vascular disease, and each parameter was assigned one point. Each one-point increment was associated with a significant increase in peri-procedural cerebrovascular events risk (OR 1.96, 95% CI 1.56-2.45, p < 0.001). The TASK score was dichotomized into very-low, low, intermediate, and high (0, 1, 2, 3-4 points, respectively). The high-risk TASK score group (OR 5.4, 95% CI 2.06-14.16, p = 0.001) was associated with a significantly higher risk of peri-procedural cerebrovascular events compared with the low TASK score group. Conclusions: The proposed novel TASK risk score may assist in the pre-procedural risk stratification of TAVR patients for peri-procedural cerebrovascular events.

Aims Most patients with significant (defined as ≥ moderate) tricuspid regurgitation (TR) are treated conservatively. Individual mortality rates are markedly variable. We developed a risk score based on comprehensive clinical and echocardiographic evaluation, predicting mortality on an individual patient level. Methods and results The cohort included 1701 consecutive patients with significant TR, half with isolated TR, admitted to a single hospital, treated conservatively. We derived a scoring system predicting 1-year mortality and validated it using k-fold cross-validation and with external validation on another cohort of 5141 patients. Score utility was compared with matched patients without significant TR. One-year mortality rate was 31.3%. The risk score ranged 0–17 points and included 11 parameters: age (0–3), body mass index ≤ 25 (0–1), history of liver disease (0–2), history of chronic lung disease (0–2), estimated glomerular filtration rate (0–5), haemoglobin (0–2), left-ventricular ejection fraction (0–1), right-ventricular dysfunction (0–1), right atrial pressure (0–2), stroke volume index (SVI) (0–1) and left-ventricular end-diastolic diameter (0–1). One-year mortality rates increased from 0 to 100%, as the score increased up to ≥16. Areas under the receiver operating curves were 0.78, 0.70, and 0.73, for the original, external validation, and external validation with SVI measured cohorts. The score remained valid in subpopulations of patients with quantified RV function, quantified TR and isolated TR. Significant TR compared to no TR, affected 1-year mortality stronger with higher scores, with a significantly positive interaction term. Conclusion We suggest a robust risk score for inpatients with significant TR, assisting risk stratification and decision-making. Our findings underscore the burden of TR providing benchmarks for clinical trial design.

Aims To evaluate the effect of an intercurrent non-coronary illness on the management and outcome of patients with non-ST-segment elevation myocardial infarction (NSTEMI). Methods and results Consecutive hospitalized patients with a primary diagnosis of NSTEMI between August 2008 and December 2019 at Sheba Medical Center. All patients’ records were reviewed for the presence of a non-coronary precipitating event (NCPE): a major intercurrent acute non-coronary illness or condition, either cardiac or non-cardiac. The primary outcome was all-cause mortality. Cox regression with interaction analysis was applied. Final study population comprised 6491 patients, of whom 2621 (40%) had NCPEs. Patients with NCPEs were older (77 vs. 69 years) and more likely to have comorbidities. The most prevalent event was infection (35%, n = 922). During a median follow-up of 30 months, 2529 patients died. Patients with NCPEs were 43% more likely to die during follow-up in a multivariable model (95% CI: 1.31–1.55). Invasive strategy was associated with a 55% lower mortality among patients without NCPE and only 44% among patients with NCPE (P for interaction < 0.001). Dual antiplatelet therapy (DAPT) was associated with a 20% lower mortality in patients without NCEP and a non-significant mortality difference among patients with NCPE (P for interaction = 0.014). Sub-analysis by the specific NCPE showed the highest mortality risk among patients with infectious precipitant. The lower mortality associated with invasive strategy was not observed in this subgroup. Conclusion Among NSTEMI patients, the presence of an NCPE is associated with poor survival and modifies the effect of management strategies.

Background: Conscious sedation (CS) has been used successfully to treat patients with severe aortic stenosis (AS) undergoing transcatheter aortic valve implantation (TAVI) and as such is considered the standard anesthesia method. The local anesthesia (LA) only approach may be feasible and safe thanks to improvements in operators’ experience. Objective: To evaluate differences between LA only versus CS approaches on short- and long-term outcomes among patients undergoing TAVI. Methods: We performed a propensity score analysis on 1096 patients undergoing TAVI for severe AS. Two hundred and seventy-four patients in the LA group were matched in a ratio of 1:3 with 822 patients in the CS group. The primary outcome was a 1-year mortality rate. Secondary outcomes included procedural and peri-procedural complication rates and in-hospital mortality. Results: Patients in the CS group had significantly higher rates of grade 2–3 acute kidney injury and were more likely to have had new left bundle branch block and high-degree atrioventricular block. Patients who underwent TAVI under CS had significantly higher in-hospital and 1-year mortality rates compared to LA (1.6% vs. 0.0% p-value = 0.036 and 8.5% vs. 3.3% p-value = 0.004, respectively). Kaplan–Meier’s survival analysis showed that the cumulative probability of 1-year mortality was significantly higher among subjects undergoing CS compared to patients LA (p-value log-rank = 0.024). Regression analysis indicated that patients undergoing CS were twice more likely to die of at 1-year when compared to patients under LA (HR 2.18, 95%CI 1.09–4.36, p-value = 0.028). Conclusions: As compared to CS, the LA-only approach is associated with lower rates of peri-procedural complications and 1-year mortality rates.

Mesenteric ischemia is a rare but lethal complication of transcatheter aortic valve replacement (TAVR). We present a challenging case of an 80-year-old man who had abdominal pain few hours following TAVR. Repeated abdominal and pelvic imaging showed no vascular obstruction, but exploratory laparoscopy revealed a necrotic bowel. (Level of Difficulty: Intermediate.), Graphical abstract

Aims The aim of this study was to estimate the burden and risk factors for ischaemic heart disease (IHD) in 195 countries and territories from 1990 to 2017. Methods and results Data from the Global Burden of Disease Study 2017 were used. Prevalence, incidence, deaths, years lived with disability (YLDs), and years of life lost (YLLs) were metrics used to measure IHD burden. Population attributable fraction was used to estimate the proportion of IHD deaths attributable to potentially modifiable risk factors. Globally, in 2017, 126.5 million [95% uncertainty interval (UI) 118.6 to 134.7] people lived with IHD and 10.6 million (95% UI 9.6 to 11.8) new IHD cases occurred, resulting in 8.9 million (95% UI 8.8 to 9.1) deaths, 5.3 million (95% UI 3.7 to 7.2) YLDs, and 165.0 million (95% UI 162.2 to 168.6) YLLs. Between 1990 and 2017, despite the decrease in age-standardized rates, the global numbers of these burden metrics of IHD have significantly increased. The burden of IHD in 2017 and its temporal trends from 1990 to 2017 varied widely by geographic location. Among all potentially modifiable risk factors, age-standardized IHD deaths worldwide were primarily attributable to dietary risks, high systolic blood pressure, high LDL cholesterol, high fasting plasma glucose, tobacco use, and high body mass index in 2017. Conclusion Our results suggested that IHD remains a major public health challenge worldwide. More effective and targeted strategies aimed at implementing cost-effective interventions and addressing modifiable risk factors are urgently needed, particularly in geographies with high or increasing burden.

Primary graft dysfunction (PGD) is a leading cause of early morbidity and mortality after heart transplantation (HT). Statins are known to have immunomodulatory and antiinflammatory effects, and perioperative statin therapy has been associated with reduced cardiovascular complications and improved outcomes after cardiac and noncardiac surgery. Thus, we investigated the influence on PGD of statin therapy administered to recipients before HT.A retrospective cohort study was conducted on 275 HT recipients assessed from 1997 to 2017; 167 (61%) had received statins during the month prior to and at time of transplantation, whereas 108 (39%) had not. Endpoints included PGD (defined according to the International Society of Heart and Lung Transplantation consensus statement), in-hospital mortality, and 1-year and 5-year survival.PGD incidence was significantly lower for statin-treated patients (21 vs 60%, P.001). Multivariable analysis demonstrated that pre-HT statin therapy was independently associated with a significant 65% reduced risk for PGD and a 73% reduced risk for in-hospital mortality. One- and five-year mortality, adjusted for age, sex, and amiodarone therapy, were significantly lower for recipients treated with statins (hazard ratio 0.33 and 0.39, 95% confidence interval 0.17-0.63 and 0.22-0.68, respectively; P = .001).Pre-HT statin therapy was independently associated with a reduced risk for PGD and mortality. Our results also suggested that statins have a beneficial prognostic impact on heart failure patients awaiting HT.

Norton scoring system is used to assess frailty of hospitalized patients with various medical conditions. We aimed to evaluate whether admission Norton scoring system predicts adverse outcomes among heart failure patients.The study population comprised 4388 acute heart failure patients between the years 2008 and 2017. Patients were allocated to 3 groups according to their admission Norton score [(≤15-low, 16-18-intermediate, and ≥19-high)]. Primary outcome included all-cause mortality at 30, 90 days, and 1 year. Multivariate Cox proportional hazards regression modeling was used to assess the independent association between Norton score and mortality. Net reclassification improvement (NRI) analysis was used to asses Norton's additive predictive ability upon known prognostic factors.Among 4388 study patients, 32% (n=1611) had low Norton score, 28% (n=1384) intermediate score, and 40% (n=1900) high score. Kaplan-Meier analysis demonstrated significantly higher 30-day mortality among patients with a low Norton score as compared with those with intermediate or high score (2.6%, 6.3%, and 16.1%; log rank p0.001). A similar trend was noted at 90 days and 1 year. Multivariate analysis found Norton score to be an independent predictor of mortality with each one-point decrement associated with a significant 15% increased risk for 30-day mortality [HR=1.15 (95%CI, 1.12-1.17) p0.001]. NRI analysis showed an improvement of 21.5% (95%CI 18.3-25.1%) predicting 1-year mortality.Our findings show that the admission Norton score is a powerful marker of short- and long-term mortality. These data suggest that the scale should be added as a risk stratification tool in this high-risk population.

Aims To estimate the prevalence, incidence, mortality, and risk factors for atrial fibrillation (AF) in 195 countries and territories from 1990 to 2017. Methods and results Following the methodologies used in the Global Burden of Disease Study 2017, the prevalence, incidence, and mortality of AF were analysed by age, sex, year, socio-demographic index (SDI), and location. The percentage contributions of major risk factors to age-standardized AF deaths were measured by population attributable fractions. In 2017, there were 37.57 million [95% uncertainty interval (UI) 32.55–42.59] prevalent cases and 3.05 million (95% UI 2.61–3.51) incident cases of AF globally, contributing to 287 241 (95% UI 276 355–304 759) deaths. The age-standardized rates of prevalent cases, incident cases, and deaths of AF in 2017 and their temporal trends from 1990 to 2017 varied significantly by SDI quintile and location. High systolic blood pressure was the leading risk factor for AF age-standardized deaths [34.3% (95% UI 27.4–41.5)] in 2017, followed by high body mass index [20.7% (95% UI 11.5–32.2)] and alcohol use [9.4% (95% UI 7.0–12.2)]. Conclusion Our study has systematically and globally assessed the temporal trends of AF, which remains a major public heath challenge. Although AF mainly occurred in developed countries, the unfavourable trend in countries with lower SDI also deserves particular attention. More effective prevention and treatment strategies aimed at counteracting the increase in AF burden should be established in some countries.

Aims Data on the association of cardiorespiratory fitness with survival of cancer patients are limited. This study aimed to evaluate the association between midlife cardiorespiratory fitness and survival after a subsequent cancer diagnosis. Methods We evaluated 19,134 asymptomatic self-referred adults who were screened in preventive healthcare settings. All subjects were free of cardiovascular disease and cancer at baseline and completed a maximal exercise stress test. Fitness was categorised into age-specific and sex-specific quintiles according to the treadmill time and dichotomised to low (quintiles 1–2) and high fitness groups. Results The mean age was 50 ± 8 years and 72% were men. During a median follow-up of 13 years (interquartile range 7–16) 517 (3%) died. Overall, 1455 (7.6%) subjects developed cancer with a median time to cancer diagnosis of 6.4 years (interquartile range 3–10). Death from the time of cancer diagnosis was significantly lower among the high fitness group (Plog rank = 0.03). Time-dependent analysis showed that subjects who developed cancer during follow-up were more likely to die (P Conclusion Higher midlife cardiorespiratory fitness is associated with better survival among cancer patients. Our findings support fitness assessment in preventive healthcare settings.

Hypomagnesemia is commonly observed in heart transplant (HT) recipients receiving calcineurin inhibitors. Since low serum magnesium (s-Mg) has been implicated in the progression of atherosclerosis, potentially leading to worsening coronary heart disease, arrhythmias and sudden death, we investigated the association between s-Mg and HT outcomes. Between 2002 and 2017, 150 HT patients assessed for s-Mg were divided into high (≥1.7 mg/dL) and low s-Mg groups according to the median value of all s-Mg levels recorded during the first 3 months post-HT. Endpoints included survival, cardiac allograft vasculopathy (CAV), any-treated rejection (ATR) and NF-MACE. Kaplan-Meier analysis showed that at 15 years after HT, both survival (76 vs 33%, log-rank p = 0.007) and freedom from CAV (75 vs 48%, log-rank p = 0.01) were higher in the high versus low s-Mg group. There were no significant differences in freedom from NF-MACE or ATR. Multivariate analyses consistently demonstrated that low s-Mg was independently associated with a significant 2.6-fold increased risk of mortality and 4-fold increased risk of CAV (95%CI 1.06 to 6.4, p = 0.04; 95%CI 1.12 to 14.42, p = 0.01, respectively). In conclusion, low s-Mg is independently associated with increased mortality and CAV in HT patients. Larger multi-center prospective studies are needed to confirm these findings and to examine the effect of Mg supplementation.

Background: Reducing door-to-balloon time may not reduce mortality, but reducing the time from symptom onset to first medical contact (FMC) may alone improve patient outcomes. The purpose of this s...

We aimed to validate a new scoring system based on extent of cardiac damage for risk stratification in patients undergoing transcatheter aortic valve replacement (TAVR) in a real-world cohort and to examine the addition of baseline albumin in risk assessment.We investigated 2608 patients undergoing TAVR. Subjects were divided into five groups based on their echocardiography findings. Patients were further assessed by incorporating baseline albumin. Multivariable analysis demonstrated that each increase in stage was associated with significant increased risk of 1-year mortality (HR 1.37, 95%CI 1.23-1.54, p .001). Among patients at increased stage (3-4), incorporation of baseline of albumin identified the highest risk group, such that each 1 decrement in albumin levels was associated with more than triple increase in mortality among patients at stage 3 and 4 (HR 2.77, 95% CI 1.48-5.18, p-value = .001).Cardiac damage classification is validated in a real-world cohort of patients undergoing TAVR. Incorporation of low baseline albumin may further identify patients at the highest risk group.We evaluated 2608 patients undergoing transcatheter aortic valve replacement (TAVR) in order to validate a new scoring system dividing patients in to 5 stages (0-4) based on extent of cardiac damage. Patients were further assessed by incorporating baseline albumin. Multivariable analysis demonstrated that each increase in stage was associated with significant increased risk of 1-year mortality. Furthermore, among patients at increased stage (3-4), incorporation of baseline of albumin identified the highest risk group, such that each 1 decrement in albumin levels was associated with more than triple increase in mortality among patients at stage 3 and 4.

Current guidelines suggest that an early invasive strategy should be considered for the treatment of non-ST-segment elevation myocardial infarction (NSTEMI). Although chronic kidney disease (CKD) is common among NSTEMI patients, these patients are under-represented in clinical trials, and data regarding their management are limited.The authors sought to evaluate the association between early invasive strategy and long-term survival among patients with NSTEMI and CKD.This was a retrospective analysis of 7,107 consecutive NSTEMI patients between 2008 and 2021. Patients were dichotomized into early (≤24 hours) and delayed invasive groups and stratified by kidney function. Inverse probability treatment weighting was used to adjust for differences in baseline characteristics. The primary outcome was all-cause mortality.The final study population comprised 3,529 invasively treated patients with a median age of 66 years (IQR: 58-74 years), 1,837 (52%) of whom were treated early. There were 483 (14%) patients with at least moderate CKD (estimated glomerular filtration rate [eGFR] 45 mL/min/1.73 mAmong NSTEMI patients, the association of early invasive strategy with long-term survival is modified by CKD and was not observed in patients with eGFR 45 mL/min/1.73 m
