Readmission following Heart failure (HF) hospitalization is common: 25% are readmitted within a month of discharge and ≈50% within 6 months. A small proportion of these patients can have multiple readmissions within this period, adding disproportionately to the health care costs. In this study, we assessed the trends, predictors and costs associated with multiple readmissions using National readmissions database (NRD).We queried NRD for HF hospitalizations from 2010 to 2018 using ICD-9/10-CM codes. Multinomial logistic regression was used to compare readmission cohorts, with the multivariable model adjusting for other factors. All analyses accounted for the NRD sampling design were conducted using SAS v. 9.4 with p0.05 used to indicate statistical significance.Within the study period, an estimated 6,763,201 HF hospitalizations were identified. Of these, 58% had no readmission; 26% had 1 readmission; and 16% had ≥2 readmissions within 90 days of index hospitalization. There was no statistically significant change in readmission rates during the observation period. Multiple readmissions which accounted for 37% of all readmissions contributed to 57% of readmission costs. Younger age was identified as a predictor of multiple readmissions while sex, comorbidities and the type of insurance were not significantly different from those with single readmission.Multiple readmissions in HF are common (16%), have remained unchanged between 2010 and 2018 and impose a significant health care cost burden. Future research should focus on identifying these patients for targeted intervention that may minimize excessive readmissions particularly in those patients who are in the palliation phase of HF.

To evaluate sex differences in in-hospital mortality and 90-day readmission rates among patients undergoing transcatheter mitral valve replacement (TMVR) in the United States of America.Women have higher rates of mortality and rehospitalization than men following many cardiac procedures. TMVR has grown as an alternative to mitral valve surgery for patients at high surgical risk. The rates of TMVR mortality and rehospitalization by sex are unknown.We analyzed the Nationwide Readmissions Database (NRD) from 2016 to 2019 to identify hospitalizations for TMVR. Sex differences in in-hospital mortality and 90-day readmissions were determined using logistic regression models.Between 2016 and 2019, 4109 hospitalizations for TMVR were identified, comprised of 1758 (42.8%) men and 2351 (57.2%) women. The median age was 74 years for both men and women. There was no significant difference in in-hospital mortality during index hospitalization (6.51% vs. 6.69%; p = 0.852) and all-cause 90-day readmission (28.19% vs. 29.59%; p = 0.563) between men and women. Across the study period, trend analysis did not reveal a significant change in in-hospital mortality (men p = 0.087, women p = 0.194) or 90-day readmission rates (men p = 0.569, women p = 0.454).In patients undergoing TMVR, in-hospital mortality and 90-day readmissions are similar between men and women. Between 2016 and 2019, TMVR in-hospital mortality and 90-day readmission rates remained unchanged. Further research is necessary to confirm these findings.

The optimal therapy for submassive pulmonary embolism (sPE), defined by right ventricular dysfunction without hemodynamic instability, is uncertain. We conducted a systematic review and meta-analysis to compare the outcomes of catheter-directed thrombolysis (CDT) versus systemic anticoagulation (SA) alone in patients with sPE. We searched PubMed, EMBASE, Cochrane, ClinicalTrials.gov, and Google Scholar (from inception through May 2022) for studies comparing outcomes of CDT versus SA in sPE. Studies were identified, and data were extracted by 2 independent reviewers. We used a random-effects model to calculate risk ratios (RRs) with 95% confidence intervals (CIs). Outcomes included in-hospital, 30-day, 90-day, and 1-year mortality, major and minor bleeding, and need for blood transfusion. A total of 12 studies (1 randomized, 11 observational) with 9,789 patients were included. Compared with SA, CDT was associated with significantly lower in-hospital mortality (RR 0.41, 95% CI 0.30 to 0.56, plt;0.00001), 30-day mortality (RR 0.37, 95% CI 0.18 to 0.73, p = 0.004), 90-day mortality (RR 0.36, 95% CI 0.17 to 0.72, p = 0.004), and a tendency toward lower 1-year mortality (RR 0.56, 95% CI 0.29 to 1.05, p = 0.07). The risks of major bleeding (RR 1.31, 95% CI 0.57 to 3.01, p = 0.53), minor bleeding (RR 1.67, 95% CI 0.77 to 3.63, p = 0.20), and the rates of blood transfusion (RR 0.34, 95% CI 0.10 to 1.15, p = 0.08) were similar between the 2 strategies. In conclusion, in patients with sPE, CDT is associated with significantly lower in-hospital, 30-day, and 90-day mortality and a tendency toward lower 1-year mortality with similar bleeding rates compared with SA. This study expands the evidence supporting CDT as first-line therapy for sPE, and randomized controlled trials are indicated to confirm our findings.

Cardiac troponin (cTn) is a type of protein found in the heart muscles. It is released into the bloodstream when heart muscles become damaged. However, cTn can also be elevated in patients with non-cardiac illnesses, such as critically ill patients and patients with acute gastrointestinal bleeding (AGIB). This study analyzed the relationship between elevated cTn and the outcomes (including prevalence, predictors and mortality) in patients with AGIB. A total of 172 patients with AGIB were evaluated. They were divided into groups based on the presence of elevated cTn. The prevalence of elevated cTn in AGIB patients was 17%. Older age, lower BMI, coronary artery disease and chronic kidney disease were found to be some of the factors that can predict cTn elevation in AGIB patients. AGIB patients with elevated cTn had more cardiology service consultations and procedures and longer lengths of hospital stay. However, there was no effect of elevated cTn on the death rate of AGIB patients.

The effect of prior coronary artery bypass graft (CABG) on the outcomes of transcatheter aortic valve replacement (TAVR) remains incompletely characterized. In this meta-analysis, we investigated the impact of prior CABG on TAVR outcomes.A systematic search was conducted in PubMed, Google Scholar, and Cochrane databases from inception to 24 July 2022, using the search terms 'TAVR', 'CABG', 'peri-procedural complications', and 'mortality'. The major outcomes were peri-procedural complications, intraprocedural mortality, 30-day mortality, and 30-day cardiac mortality. We used random-effects models to aggregate data and to calculate pooled incidence and risk ratios with 95% confidence intervals (CIs).Among 116 results from the systematic search, a total of 8 studies (5952 patients) were included. Compared to patients without previous CABG, patients with prior CABG undergoing TAVR were younger, predominantly male sex, had more comorbidities, higher rates of peri-procedural myocardial infarction (MI) [relative risk (RR) 1.93; 95% CI, 1.09-3.43; P = 0.03], but lower rates of stroke (RR 0.71; 95% CI, 0.51-0.99; P = 0.04), major vascular complications (RR 0.70; 95% CI, 0.51-0.95; P = 0.02), and major bleeding (RR 0.70; 95% CI, 0.56-0.88; P = 0.002). There were no significant differences between the two cohorts in rates of pacemaker implantation, cardiac tamponade, acute kidney injury, intra-procedural mortality, 30-day mortality, and 30-day cardiac mortality.Among patients undergoing TAVR, a history of prior CABG was not associated with an increased risk of periprocedural complications (except for acute MI) or short-term mortality compared to those without CABG.

We aimed to study the efficacy of cardiac magnetic resonance imaging (CMR) and intracoronary optical coherence tomography (OCT) in detecting the etiology of myocardial infarction with non-obstructive coronary arteries (MINOCA). A systematic search was conducted in PubMed, Medline, and Cochrane databases. Search terms used: Myocardial infarction, Coronary angiography, Normal coronary arteries, CMR, and OCT. Inclusion criteria was fulfilled by 18 studies. Meta-analysis was performed with 15 studies. A total of 2697 patients were included. The mean age of all the patients was 51.5 and 56.4% were men. CMR established diagnosis in 74% of the patients; 29% had acute myocarditis, 18% had true myocardial infarction and 12% had takotsubo cardiomyopathy. Combining OCT with CMR was better at finding the etiology than either modality individually. The findings of this study conclude that CMR is integral in identifying the etiology of MINOCA. Coupling OCT and CMR is better than either technique individually at finding the cause.

Optical coherence tomography (OCT) and intravascular ultrasound (IVUS) optimize percutaneous coronary intervention (PCI) by characterizing lesion morphology, accurately measuring vessel dimensions, and optimizing stent characteristics. We sought to compare the utilization of OCT and IVUS to guide inpatient PCI and their relative association with in-hospital mortality and readmission rates. We queried the National Readmission Database to identify patients undergoing intracoronary imaging-guided PCI from 2010 to 2019 and compared outcomes and readmission rates between patients undergoing OCT-guided PCI and IVUS-guided PCI. Multivariable logistic regression was performed to generate adjusted odds ratios (aOR) of adverse outcomes between the 2 groups. Of 3,71,450 intracoronary imaging-guided PCI admissions, OCT (n = 12,808) was used less frequently than IVUS (n = 358,642). The use of OCT-guided PCI increased from 0.1% in 2010 to 0.6% in 2019 while the rate of IVUS-guided PCI increased from 7.2% in 2010 to 9.4% in 2019 (both ptrend0.001). Patients undergoing OCT compared to IVUS had lower in-hospital mortality (aOR 0.69, P = 0.015) and 30-day readmission rate (aOR 0.91, P = 0.040) with no statistical difference in 90-day readmission rate (aOR 0.93, P = 0.065). Heart failure was the most common cause of 30-day and 90-day readmissions in both cohorts. There was no difference in the rate of acute kidney injury between the 2 modalities. In this in-patient admission database of intracoronary imaging-guided PCI, OCT-guided PCI during index hospitalization appears to be associated with lower in-hospital mortality and 30-day readmission rates compared to IVUS-guided PCI with no difference in terms of the 90-day readmission rates.

There is a paucity of data on the management and outcomes of chronic viral hepatitis (CVH) patients [including chronic hepatitis B (CHB) and chronic hepatitis C (CHC)] presenting with acute myocardial infarction (AMI).We utilized the National Inpatient Sample database (2001-2019) and studied the management and outcomes of CVH patients with AMI and stratified them by subtypes of CVH. The adjusted odds ratio (aOR) of adverse outcomes in CVH groups were compared to no-CVH groups using multivariable logistic regression.Of 18,794,686 AMI admissions, 84,147 (0.45%) had a CVH diagnosis. CVH patients had increased odds of adverse outcomes including in-hospital mortality (aOR 1.40, 95%CI 1.31-1.49, p 0.05), respiratory failure (1.11, 95%CI 1.04-1.17, p 0.001), vascular complications (1.09, 95%CI 1.04-1.15, p 0.001), acute kidney injury (1.36, 95%CI 1.30-1.42, p 0.001), gastrointestinal bleeding (1.57, 95%CI 1.50-1.68, p 0.001), cardiogenic shock (1.44, 95%CI 1.04-1.30, p 0.001), sepsis (1.24, 95%CI 1.17-1.31, p 0.001), and were less likely to undergo invasive management. On subgroup analysis, CHB had higher odds of adverse outcomes than the CHC group (p 0.05).CVH patients presenting with AMI are associated with worse clinical outcomes. CHB subgroup had worse outcomes compared to the CHC subgroup.

Management of right atrial appendage (RAA) thrombus is a clinical dilemma. We describe a case of incidentally found RAA thrombus in a patient with a left atrial appendage closure device (WATCHMAN). Options for the management of RAA thrombus include observation, anticoagulation, thrombolytics, or surgical extraction. Size, mobility, site of attachment of the thrombi, patient factors (e.g., bleeding risk), and other indications for anticoagulation may be used to guide management.

To assess readmission rates in nonagenarians (age ≥ 90 years) with ST-elevation myocardial infarction (STEMI) following primary percutaneous coronary intervention (pPCI) versus no pPCI.There are limited data exploring readmissions following STEMI in nonagenarians undergoing pPCI versus no pPCI.We retrospectively analyzed the Nationwide Readmissions Database to identify nonagenarians hospitalized with STEMI. We divided the cohort into two groups based on pPCI status. We compared mortality during index hospitalization and during 30-day readmission, readmission rates, and causes of readmissions.We identified 58,231 nonagenarian STEMI hospitalizations between 2010 and 2018, of which 18,809 (32.3%) included pPCI, and 39,422 (67.7%) had no pPCI. Unadjusted unplanned 30-day readmission was higher in pPCI cohort (21.0% vs. 15.4%, p 0.001). However, mortality during index hospitalization and during 30-day readmission were significantly lower in pPCI cohort (15.8% vs. 32.2%, p 0.001; 7.4% vs. 14.2%, p 0.001, respectively). After adjusting for baseline characteristics, hospitalizations that included pPCI had 25% greater odds of unplanned 30-day readmission (adjusted odds ratio [aOR]: 1.25, 95% confidence interval [CI]: 1.12-1.39, p 0.001) and 49% lower odds of in-hospital mortality during index hospitalization (aOR: 0.51, 95% CI: 0.46-0.56, p 0.001). Heart failure was the most common cause of readmission in both cohorts followed by myocardial infarction.In nonagenarians with STEMI, pPCI is associated with slightly higher 30-day readmission but significantly lower mortality during index hospitalization and during 30-day readmission than no pPCI. Given the overwhelming mortality benefit with pPCI, further research is necessary to optimize the utilization of pPCI while reducing readmissions following STEMI in nonagenarians.

A 28-year-old woman with a history of systemic lupus erythematosus on hydroxychloroquine and steroid therapy presented with fever, dysentery, and thrombocytopenia. Marrow aspirate revealed yeast forms of histoplasmosis. She was treated with liposomal amphotericin B followed by itraconazole with resolution of symptoms and marrow recovery.

While aortic valve replacement (AVR) is indicated for symptomatic severe aortic stenosis (AS), the appropriate management of asymptomatic severe AS remains unclear. We conducted an updated meta-analysis to compare the outcomes of surgical AVR (SAVR) versus conservative treatment in patients with asymptomatic severe AS.We searched PubMed, EMBASE, Cochrane, clinicaltrials.gov, and Google Scholar for studies comparing outcomes of SAVR versus conservative treatment in asymptomatic severe AS. Risk ratios (RRs) and 95% confidence intervals (CIs) were calculated for each individual study. Outcomes included all-cause mortality, cardiovascular and non-cardiovascular mortality, 30-day operative mortality, sudden cardiac death (SCD), heart failure hospitalization (HFH), myocardial infarction (MI), and stroke.A total of 8 studies with 2685 patients were included. The mean age was above 60 years, and the median follow-up duration was 4 years. Compared to conservative treatment, SAVR was associated with significantly lower all-cause mortality (RR 0.39; 95% CI 0.23-0.64) and HFH rates (RR 0.18; 95% CI 0.05-0.71). There were no significant differences in cardiovascular mortality (RR 0.24; 95% CI 0.03-1.67), non-cardiovascular mortality (RR 0.49; 95% CI 0.23-1.03), 30-day operative mortality (RR 0.48; 95% CI 0.10-2.32), SCD (RR 0.37; 95% CI 0.05-2.89), MI (RR 0.48; 95% CI 0.04-5.52), and stroke rates (RR 1.20; 95% CI 0.35-4.11) between the two strategies.In patients with asymptomatic severe AS, SAVR is associated with significantly lower all-cause mortality and HFH compared to conservative treatment. While SAVR is a promising option for asymptomatic severe AS, most studies were observational and nonrandomized; randomized trials are needed to establish a clear benefit.

Background: Myocardial Infarction with Non-Obstructive Coronary arteries (MINOCA) is defined as acute Myocardial Infarction (MI) despite the absence of severe coronary artery stenosis on angiography (i.e., stenosis severity Methods: A systematic search was made in PubMed, Medline and Cochrane database. Search terms used: Myocardial infarction, Coronary angiography, Normal coronary arteries, CMR, and OCT. Inclusion criteria was fulfilled by 18 studies. Meta-analysis and meta-regression was performed with 14 studies due to increased heterogeneity. Results: A total of 2474 patients were included in the meta-analysis. The mean age of all the patients was 51.5 and 56.4% were men. CMR was able to establish diagnosis in 74% of the patients; 30.4% had AM, 21.3% had true MI and 12% had TCM. Upon meta-regression the demographic variables, cardiovascular risk factors, troponin levels and C-reactive protein levels did not have any association with AM or MI. Incorporation of OCT with CMR was better at finding the etiology than either modalities individually. Conclusion: CMR is integral in finding the cause of MINOCA. Coupling coronary OCT and CMR is better than either techniques alone at identifying the etiology.

Chemotherapeutic regimens have cardiotoxic properties and thorax irradiation is associated with accelerated coronary artery disease (CAD). There is limited data regarding the influence of cancer on outcomes after percutaneous coronary intervention (PCI), as cancer patients were not routinely included in the PCI trials. We performed a systematic review and meta-analysis to compare the early outcomes of PCI between patients with active/historical cancer and patients without a cancer history. A systematic search was made in the PubMed, Medline, and Cochrane databases using the search terms "PCI" and "Cancer". The major outcomes were in-hospital mortality, in-hospital cardiovascular mortality, 30-day mortality, and peri-procedural complications. We used random effects model to aggregate data and calculate pooled incidence and risk ratios with 95% confidence intervals (CIs). A total of 7 studies were included, out of which 4 studies reported in-hospital mortality. Compared to patients without cancer, patients with active/historical cancer undergoing PCI had higher rates of in-hospital mortality (relative risk [RR] 1.89; 95% CI 1.33-2.70; P = 0.0004), in-hospital cardiovascular mortality (RR 2.21; 95% CI 1.19-4.08; P = 0.01), 30-day mortality (RR 2.01; 95% CI 1.24-3.27; P = 0.005), and peri-procedural blood transfusion (RR 1.73; 95% CI 1.02-2.95; P = 0.04). There were no significant differences in peri-procedural myocardial re-infarction, new-onset heart failure, shock, and stroke between the two cohorts. In conclusion, Among patients undergoing PCI, active/historical cancer was associated with worse early mortality compared to patients without a history of cancer. Management of cancer patients undergoing PCI should be individualized and involve multi-specialist team discussion to narrow the mortality gap.
