Direct oral anticoagulants (DOAC) versus vitamin K antagonist in left ventricular thrombus: An updated meta-analysis.

Background and Aims: Current clinical guidelines for treating left ventricular thrombus (LVT) are limited by inadequate evidence to inform the comparative efficacy of oral anticoagulants. In this meta-analysis, we aimed to compare the efficacy and safety of direct oral anticoagulants (DOAC) to vitamin K antagonists (VKA) in patients with LVT. Methods: Four standard databases were searched for relevant literature comparing the efficacy and safety between DOAC and VKA for LVT treatment, published before August 19, 2023. Both the randomized controlled trials and observational studies were included in the analysis. The outcomes of interest were the resolution of LVT, all-cause mortality, stroke, systemic embolism, and bleeding. Data from the selected studies were extracted and analyzed using RevMan 5.4 using odds ratio. Results: Among 3959 studies from the database search and bibliography review, 33 were included in the analysis. LVT resolution was observed in 72.59% in the DOAC group versus 67.49% in the VKA group (odds ratio [OR]: 1.28, confidence interval [CI]: 1.07-1.53). Mortality was lower in the DOAC group (11.71% vs. 18.56%) (OR: 0.60, CI: 0.36-1.00; borderline statistical significance). Likewise, bleeding events (9.60% vs. 13.19%) (OR: 0.65, CI: 0.52-0.81) and stroke (7.54% vs. 11.04%) (OR: 0.71, CI: 0.53-0.96) were also significantly lower in the DOAC group. Conclusion: DOAC use for LVT showed better thrombus resolution and reduced risk of bleeding and stroke compared to VKA. Likewise, DOAC use was associated with lower mortality with borderline statistical significance.

Impact of Chronic Kidney Disease on In-Hospital Outcomes of Hospitalizations With Acute Limb Ischemia Undergoing Endovascular Therapy.

PURPOSE: Studies on outcomes related to endovascular treatment (EVT) in advanced stages of chronic kidney disease (CKD) and end-stage renal disease (ESRD) among hospitalizations with acute limb ischemia (ALI) are limited. METHODS: The Nationwide Inpatient Sample was quarried from October 2015 to December 2017 to identify the hospitalizations with ALI and undergoing EVT. The study population was subdivided into 3 groups based on their CKD stages: group 1 (No CKD, stage I, stage II), group 2 (CKD stage III, stage IV), and group 3 (CKD stage V and ESRD). The primary outcome was all-cause in-hospital mortality. RESULTS: A total of 51 995 hospitalizations with ALI undergoing EVT were identified. The in-hospital mortality was significantly higher in group 2 (OR = 1.17; 95% CI 1.04 - 1.32, p=0.009) and group 3 (OR = 3.18; 95% CI 2.74-3.69, p<0.0001) compared with group 1. Odds of minor amputation, vascular complication, atherectomy, and blood transfusion were higher among groups 2 and 3 compared with group 1. Group 2 had higher odds of access site hemorrhage compared with groups 1 and 3, whereas group 3 had higher odds of major amputation, postprocedural infection, and postoperative hemorrhage compared with groups 1 and 2. Besides, groups 2 and 3 had lower odds of discharge to home compared with group 1. Finally, the length of hospital stay and cost of care was significantly higher with the advancing CKD stages. CONCLUSION: Advanced CKD stages and ESRD are associated with higher mortality, worse in-hospital outcomes and higher resource utilization among ALI hospitalizations undergoing EVT. CLINICAL IMPACT: Current guidelines are not clear for the optimum first line treatment of acute limb ischemia, especially in patients with advanced kidney disease as compared to normal/mild kidney disease patients. We found that advanced kidney disease is a significant risk factor for worse in-hospital morbidity and mortality. Furthermore, patients with acute limb ischemia and advanced kidney disease is associated with significantly higher resource utilization as compared to patients with normal/mild kidney disease. This study suggests shared decision making between treating physician and patients when considering endovascular therapy for the treatment of acute limb ischemia in patients with advanced kidney disease.

Colchicine for Patients With Coronary Artery Disease: A Systematic Review and Meta-analysis.

ABSTRACT: Several randomized controlled trials have studied the role of colchicine, a potent anti-inflammatory drug, to prevent adverse cardiovascular events in patients with coronary artery disease (CAD). In this meta-analysis, we aimed to determine the role of colchicine in patients with CAD in clinical outcomes and mortality. We searched PubMed, PubMed Central, Scopus, and Embase for randomized controlled trials/experimental studies evaluating the role of colchicine in patients with CAD. After assessing the eligibility for inclusion, risk-of-bias assessment, and data extraction from the included studies, a narrative synthesis was conducted. Of 17 studies included for the qualitative analysis, 11 studies reported that inflammatory markers such as C-reactive protein and cytokines were reduced in the colchicine group, suggesting an anti-inflammatory role of colchicine in CAD. Quantitative analysis with pooling of data from 9 studies using a fixed-effect model showed 28% lower odds of acute myocardial infarction [odds ratio (OR) 0.72, 95% CI 0.59-0.86; n = 11,712], 52% lower occurrence of stroke (OR 0.48, 95% CI 0.30-0.76), and 37% reduction in odds of coronary revascularization procedure in the colchicine group (OR 0.63, 95% CI 0.52-0.76; n= 11,258). However, the odds of gastrointestinal adverse events were 50% higher in the colchicine group (OR 1.50, 95% CI 1.01-2.23; n = 12,214). In conclusion, colchicine is associated with a lower risk of acute myocardial infarction, stroke, and coronary revascularization. However, there is some increased risk of gastrointestinal adverse events with the use of colchicine.

Sodium-glucose cotransporter-2 Inhibitors in Heart Failure: An Updated Systematic Review and Meta-analysis of 13 Randomized Clinical Trials Including 14,618 Patients With Heart Failure.

ABSTRACT: Sodium-glucose cotransporter-2 (SGLT-2) inhibitors showed benefit in patients with heart failure. In this updated meta-analysis, we evaluate the therapeutic efficacy and safety of SGLT-2 inhibitors in patients with heart failure. Different electronic databases were searched to find relevant articles. RevMan 5.4 was used for pooling data using a random/fixed-effects model, complemented by several sensitivity and subgroup analyses. A total of 13 randomized clinical trials including 14,618 patients with heart failure were included in analysis among 6797 studies screened. The overall mortality rate was 12.45% in the SGLT-2 group and 14.67% in the placebo group with 18% lower odds of overall mortality [odds ratio (OR), 0.82; confidence interval (CI), 0.75-0.91] in the SGLT-2 group. Odds of cardiovascular mortality was 18% lower (OR, 0.82; CI, 0.74-0.92) in the SGLT-2 group. The odds of hospitalization for heart failure (HHF) was 38% lower during the study period (OR, 0.62; CI, 0.56-0.68) in the SGLT-2 group. In addition, a benefit was seen for composite outcome HHF or mortality and considering subgrouping based on diabetes status, gender, and age groups. Although genital infection was significantly higher in the SGLT-2 group, the occurrence of severe adverse events, hypoglycemia, urinary tract infection, bone fracture, volume depletion, and other renal events did not differ between the 2 groups. Thus, SGLT-2 inhibitors improved cardiovascular outcomes among patients with heart failure with no significant difference in adverse events. Clinical benefit was comparable in diabetic and nondiabetic individuals, males and females, people in younger and older age groups with underlying heart failure, and HF with reduced ejection fraction.

Short term outcomes after transcatheter mitral valve repair.

BACKGROUND: Outcome data following transcatheter mitral valve repair (TMVR) with the MITRACLIP® device are scarce outside the pivotal randomized controlled trials. METHODS: The Nationwide Readmission Data base (NRD) was utilized for years 2013-2017 to identify the study population. Thirty-day readmission pattern, in-hospital complications, causes of readmissions, and multivariate predictors for readmission, complications and mortality were explored. RESULTS: We noted a total of 14,647 index admissions related to MITRACLIP of which 48% of procedures were performed at high volume centers (Annual hospital volume ≥ 25). A total of 15% of patients were readmitted within 30 days of discharge most frequently due to cardiac causes. Approximately 33% of patients were discharged within 24 h of the procedure. The in-hospital mortality rate was 2.8% and in-hospital complication rate was 14.6%. The most common complications were cardiac complications (8.2%), bleeding related complications (5.9%) and vascular complications (0.65%). On multivariate modeling, female sex, CHF, Atrial fibrillation, prior PCI, COPD, CKD, transfer to skilled nursing facility, length of stay ≥2 days were associated with a high risk of readmission. Additionally, coagulopathy, chronic kidney disease and lengthier hospital stays were associated with high risk of complication or death. CONCLUSION: The 30-day readmission rate following commercial treatment with the MITRACLIP device is 15%. Half of these admission were from a cardiac etiology. Heart failure, atrial arrhythmias and clip related complications round out the top 3 cardiac reasons for readmission. There was no impact of hospital size, teaching status or case volume on mortality and in hospital complication rates.

Peripheral Arterial Disease in Women: The Gender Effect.

Peripheral arterial disease (PAD) is a common atherosclerotic disease approximately affecting 8.5 million Americans above age 40 and is associated with significant functional impairment, morbidity and mortality from both cardiovascular and non-cardiovascular causes. PAD has increasing prevalence in females contrary to previous findings. Compared to men, women with PAD are more asymptomatic or have atypical symptoms. Women with PAD have increased quality of life impairment, increased risk of depression and increased cardiovascular mortality. The intent of this review is to provide an update on gender differences in PAD that can help in timely diagnosis and appropriate management through intensive cardiovascular risk factor modification, exercise program and guideline directed therapy to improve cardiovascular outcomes.

Trends in Incidence and Outcomes of Pregnancy-Related Acute Myocardial Infarction (From a Nationwide Inpatient Sample Database).

Acute myocardial infarction (AMI) during pregnancy is rare but fatal complication. Recent incidence of pregnancy related AMI and trends in the related outcomes are unknown. The Nationwide Inpatient Sample database was utilized from years 2005 to 2014. International Classification of Disease-Ninth Revision were used to identify pregnancy related admissions and AMI. Primary outcome was incidence and trend of AMI related to pregnancy and Secondary outcomes were trends in mortality, resource utilization, and predictors of AMI during pregnancy. Simple logistic regression model was used to calculate predictors of AMI during pregnancy. p Values for trends were generated by Cochrane-Armitage test for categorical variables and simple linear regression for continuous variables. A total of 43,437,621 pregnancy related hospitalization and 3,786 cases of AMI (86% ante-partum and 14% postpartum) were noted during study period. The incidence of AMI during the study period was 8.7 per 100,000 pregnancies with an overall increase in incidence during the study period (relative increase of 18.9%, p <0.001). There was a concomitant decrease in mortality (relative decrease of 40.05%, p <0.001), cost of care (relative decrease of 8.70%, p <0.001), and length of stay (relative decrease of 13.53%, p <0.001). Significant predictors of AMI during pregnancy were higher age of pregnancy, black race, co-morbidities such as hypertension, thrombophilia, diabetes milletus, substance abuse, smoking, hyperlipidemia, heart failure, deep venous thrombosis, transfusion, fluid and electrolyte imbalance, and postpartum complications such as hemorrhage, infection, and depression. In conclusion, the incidence of AMI 2005 to 2014 rose with a concomitant decrease in mortality and resource utilization. High-risk patient characteristics were identified which could be utilized for resource allocation to further improve outcomes.

Revascularization of Left Main Coronary Artery.

Left main coronary artery (LMCA) disease affect 5-7% of patient undergoing coronary angiography and is associated with multivessel CAD in 70% of the cases. Untreated significant LMCA disease is associated with significant mortality and morbidity. CABG is the traditional therapy for revascularization in LMCA disease. PCI is a reasonable alternative mainly in patients with high surgical risk or other specific factors. Drug-eluting stents, improved antiplatelet therapeutic options, atherectomy techniques, IVUS-guidance and improved operator experience have all contributed to the observed improvement in clinical outcomes. Given the large number of variables involved in deciding between PCI and CABG, a heart team should make decisions regarding revascularization of LMCA disease.

Sex differences in short-term and long-term all-cause mortality among patients with ST-segment elevation myocardial infarction treated by primary percutaneous intervention: a meta-analysis.

IMPORTANCE: Although outcomes in patients with ST-segment elevation myocardial infarction (STEMI) have improved in the past 2 decades, a sex disparity exists in survival, with women having higher mortality than men. OBJECTIVE: To conduct a meta-analysis of observational studies that examined differences in mortality by sex in patients with STEMI treated with primary percutaneous coronary intervention (PPCI). DATA SOURCES: MEDLINE, EMBASE, Cochrane central, and electronic databases were searched for relevant studies in all languages and without time restriction. STUDY SELECTION: Studies were included if (1) they studied patients who presented with STEMI, (2) primary percutaneous coronary intervention (PPCI) was the treatment for STEMI, (3) PPCI was performed within 12 hours of symptom onset, and (4) sex-specific in-hospital and/or 1-year mortality were reported. DATA EXTRACTION AND SYNTHESIS: Two investigators independently reviewed retrieved citations and assessed eligibility. Discrepancies were resolved by consensus. Quality of included studies was assessed using Newcastle-Ottawa Quality Assessment Scale for cohort studies. Data were pooled using a random-effects model. MAIN OUTCOMES AND MEASURES: Sex-specific in-hospital and 1-year all-cause mortality. Risk ratios (RRs) of mortality were used for these 2 time points, if reported. RESULTS: Of the 149 studies identified, 35 met inclusion criteria, representing 18 555 women and 49 981 men. In the unadjusted analyses, women were at a higher risk for in-hospital (RR, 1.93; 95% CI, 1.75-2.14 [P < .001, I2 = 14%]) and 1-year all-cause mortality (RR, 1.58; 95% CI, 1.36-1.84 [P < .001, I2 = 51%]) compared with men. However, when adjusted RRs were used, the association between women and higher risk of all-cause mortality was attenuated but still significantly elevated for in-hospital mortality (RR, 1.48; 95% CI, 1.07-2.05 [P = .02, I2 = 56%]), but the higher risk for 1-year mortality in women was no longer significant (RR, 0.90; 95% CI, 0.69-1.17 [P = .42, I2 = 58%]). CONCLUSIONS AND RELEVANCE: An increased mortality in women with STEMI treated with PPCI was detected in this large meta-analysis but is likely confounded by baseline cardiovascular risk factors and the differences in clinical profile of male and female patients with STEMI. Intensive cardiovascular risk modification efforts in women may help to reduce this sex disparity.

Primary pericardial mesothelioma unique case and literature review.

A 72-year-old woman, on warfarin therapy and with a remote history of breast cancer and radiation treatment, presented with a 10-day history of nausea, dyspnea, dry cough, and dizziness. An electrocardiogram showed new-onset atrial fibrillation. Computed tomography of the chest revealed multiple pulmonary emboli and a pericardial effusion. Echocardiography showed a pericardial effusion with tamponade characteristics. The patient's condition deteriorated, and a pericardiectomy was performed. Histologic evaluation confirmed primary pericardial mesothelioma. She underwent palliative treatment and died 3 months after discharge from the hospital. We discuss the patient's case and the nature of primary pericardial mesothelioma, a rare oncologic entity.
