    Abstract Background: Late gadolinium enhancement (LGE) on cardiac magnetic resonance is a predictor of adverse events in patients with nonischemic cardiomyopathy (NICM).
    Objective: This meta-analysis evaluated the correlation between LGE and mortality, ventricular arrhythmias (VAs) and sudden cardiac death (SCD), and heart failure (HF) outcomes.
    Methods: A literature search was conducted for studies reporting the association between LGE in NICM and the study endpoints. The primary endpoint was mortality. Secondary endpoints included VA and SCD, HF hospitalization, improvement in left ventricular ejection fraction (LVEF) to >35%, and heart transplantation referral. The search was not restricted to time or publication status. The minimum follow-up duration was 1 year.
    Results: A total of 46 studies and 10,548 NICM patients (4610 with LGE, 5938 without LGE) were included; mean follow-up was 3 years (range 13-71 months). LGE was associated with increased mortality (odds ratio [OR] 2.9; 95% confidence interval [CI] 2.3-3.8;
    Conclusion: LGE in NICM patients is associated with increased mortality, VA and SCD, and HF hospitalization and heart transplantation referral during long-term follow up. Given these competing risks of mortality and HF progression, prospective randomized controlled trials are required to determine if LGE is useful for guiding prophylactic implantable cardioverter-defibrillator placement in NICM patients.

    Abstract The use of cardiac imaging has become increasingly prevalent over the last decade. Approximately 10% to 15% of noninvasive cardiac imaging is ordered for rarely appropriate indications. The appropriate use criteria (AUC) for cardiac imaging were issued to decrease unnecessary testing and reduce health care costs. However, it remains unclear whether these efforts have been successful. This meta-analysis evaluates whether AUC quality improvement (QI) interventions effectively reduce inappropriate cardiac imaging. Databases were searched for studies reporting QI intervention effect aiming to reduce rarely appropriate noninvasive cardiac imaging based on AUC. Imaging modalities assessed include transthoracic echocardiography, stress echocardiography, and myocardial perfusion imaging. We searched Ovid MEDLINE, EMBASE, Scopus, Web of Science, Google Scholar, and EBSCO CINAHL. The primary end point was a decrease of rarely appropriate testing. The search was not restricted to time or publication status. The literature search identified 2,391 possible studies, 13 studies and 26,557 patients were included. Mean follow-up was 12 months (1 to 60 months). QI interventions were statistically significant in reducing rarely appropriate tests after the intervention compared with the control group (odds ratio [OR] 0.51, 95% confidence interval [CI] 0.41 to 0.64, p <0.01). The QI interventions were also assessed for persistence based on short-term (<3 months) and long-term (>3 months) efficacy. Both the short-term effect and long-term effect were persistent (OR 0.6, 95% CI 0.47 to 0.77, p <0.01 and OR 0.47, 95% CI 0.37 to 0.61, p <0.01, respectively). AUC QI interventions are associated with the successful decrease of inappropriate noninvasive cardiac testing with these effects persisting over time.

    Abstract Background: The volume of cardiac imaging continues to increase, with many tests performed for rarely appropriate indications. Appropriate use criteria (AUC) documents were published by the American Society of Echocardiography and American College of Cardiology, with quality improvement (QI) interventions developed in various institutions. However, the effectiveness of these interventions has not been assessed in a systematic fashion.
    Methods: We searched Ovid MEDLINE, EMBASE, Scopus, Web of Science, Google Scholar, and EBSCO CINAHL for studies reporting association between cardiac imaging, AUC and QI. The search was not restricted to time or publication status. We selected studies assessing the effect of QI interventions on performance of rarely appropriate echocardiograms. The primary endpoint was reduction of rarely appropriate testing.
    Results: Nine studies with 22,070 patients met inclusion criteria. Mean follow up was 15 months (1-60 months). QI interventions resulted in statistically significant reduction in rarely appropriate tests (OR 0.52, 95% CI: .41-.66; p < .01). The effects of QI interventions were analyzed over both the short (<3 months) and long-term (>3 months) post intervention (OR 0.62, 95% CI: .49-.79; p < .01 in the short term, and OR 0.47, 95% CI: .35-.62; p < .01 in the long term). Subgroup analysis of the type of intervention, classified as education tools or decision support tools showed both significantly reduced rarely appropriate testing (OR 0.54, 95% CI: .41-.73; p < .01; OR .47, 95% CI: .36-.61; p < .01). Adding a feedback tool did not change the effect compared to not using a feedback tool (OR 0.49 vs. 0.57, 95% CI: .36-.68 vs. 39-.84; p > .05).
    Conclusion: QI interventions are associated with a significant reduction in performance of rarely appropriate echocardiography testing, the effects of which persist over time. Both education and decision support tools were effective, while adding feedback tools did not result in further reduction of ordering rarely appropriate studies.

    Abstract Background: Previous studies have shown that women with atrial fibrillation (AF) have a higher incidence of recurrence and non-pulmonary vein (non-PV) triggers. However, there remains an incomplete understanding of the impact of gender on AF ablation strategies and outcomes.
    Objective: The purpose of this study was to evaluate the impact of gender on AF ablation outcomes.
    Methods: We analyzed 1568 AF ablations in 1412 patients (34% female) performed at a single tertiary care center between January 2013 and July 2021. Patients were followed for at least 6 months (mean 34 months) for detection of AF recurrence, complications, and emergency department visits/hospitalizations. The effect was assessed by multivariate logistic regression analysis using propensity score matching (PSM).
    Results: Mean age was 64 years, and mean body mass index (BMI) was 31 kg/m
    Conclusion: There was no difference in overall safety or efficacy outcomes between genders after AF ablation.

    Abstract Background: Glucagon-like Peptide-1 Receptor Agonists (GLP-1 RA) are frequently used for the management of diabetes. The impact of GLP-1 RA on cardiovascular outcomes is unclear. We aim to assess the effect of GLP-1 RA on mortality, atrial and ventricular arrhythmias, and sudden cardiac death in patients with type II diabetes.
    Methods: We searched databases including Ovid MEDLINE, EMBASE, Scopus, Web of Science, Google Scholar and CINAHL, from inception to May 2022, for randomized controlled trials reporting the relationship between GLP-1 RA (including albiglutide, dulaglutide, exenatide, liraglutide, lixisenatide, and semaglutide) and mortality, atrial arrhythmias, and the combined incidence of ventricular arrhythmias and sudden cardiac death. The search was not restricted to time or publication status.
    Results: A total of 464 studies resulted from literature search, of which 44 studies, including 78,702 patients (41,800 GLP-1 agonists vs 36,902 control), were included. Follow up ranged from 52 to 208 weeks. GLP-1 RA were associated with lower risk of all-cause mortality (odds ratio 0.891, 95% confidence interval 0.837-0.949; P < 0.01) and reduced cardiovascular mortality (odds ratio 0.88, 95% confidence interval 0.881-0.954; P < 0.01). GLP-1 RA were not associated with increased risk of atrial (odds ratio 0.963, 95% confidence interval 0.869-1.066; P 0.46) or ventricular arrhythmias and sudden cardiac death (odds ratio 0.895, 95% confidence interval 0.706-1.135; P 0.36).
    Conclusion: GLP-1 RA are associated with decreased all-cause and cardiovascular mortality, and no increased risk of atrial and ventricular arrhythmias and sudden cardiac death.

    Abstract Background: The beneficial role of dual anti-platelet therapy (DAPT) in coronary artery disease is well established. However, there is limited data describing the effects of DAPT in patients with atherosclerotic peripheral artery disease (PAD). The aim of this meta-analysis is to compare clinical outcomes associated with DAPT versus single anti-platelet therapy (SAPT) in patients with symptomatic PAD.
    Methods: We performed a literature search for studies assessing the risk of adverse cardiovascular and limb events in cohorts receiving either DAPT or SAPT. The primary endpoint was all cause mortality. The secondary endpoints included graft failure, amputation, total bleeding, severe bleeding and fatal bleeding. The search included the following databases: Ovid MEDLINE, EMBASE, Web of Science, and Google Scholar. The search was not restricted to time or publication status.
    Results: A total of 11 studies with 54,331 participants (24,449 on SAPT and 29,882 on DAPT) were included. Patients with PAD treated with SAPT had higher all-cause mortality compared to patients treated with DAPT (OR 1.37, 95 % CI 1.09-1.74; p < 0.01). There was no difference in risk of graft failure or amputation between patients treated with SAPT or DAPT (OR 0.9, 95 % CI 0.77-1.06; p = 0.19; OR 1.11, 95 % CI 0.88-1.41; p = 0.37). Patients treated with SAPT had lower total bleeds compared to patients treated with DAPT (OR 0.53, 95 % CI 0.36-0.77; p < 0.01). However, For SAPT plus AC vs SAPT, a total of 8 studies with 17,100 participants (3447 with SAPT plus AC and 8619 with only SAPT) were included. Patients on SAPT plus AC did not have a statistically significant difference in risk for all-cause mortality, (OR 0.91, 95 % CI 0.67-1.24; p = 0.56). SAPT plus AC had significantly lower risk of MI (OR 0.82, 95 % CI 0.69-0.97; p = 0.02), amputation (OR 0.72, 95 % CI 0.53-0.97; p = 0.03), and graft failure (OR 0.66, 95 % CI 0.48-0.93; p = 0.02). There was no significant different in risk of fatal bleeding be-tween the two groups (OR 1.60, 95 % CI 0.76-3.35; p = 0.22).
    Conclusions: In patients with symptomatic PAD, a strategy of DAPT may confer a mortality benefit when compared to SAPT without significantly increasing the risk of serious bleeding events.

    Abstract Background: Revascularization in patients with left ventricular (LV) dysfunction has been a subject of ongoing uncertainty and conflicting results. This is further complicated by factors including viability, severity of LV dysfunction, and method of revascularization using percutaneous coronary intervention (PCI) versus coronary-artery bypass grafting (CABG).
    Objectives: The purpose of this meta-analysis is to evaluate the association of coronary revascularization with outcomes in patients with ischemic LV dysfunction.
    Methods: A literature search was conducted for studies reporting on cardiovascular outcomes after revascularization compared to optimal medical therapy (OMT) in patients with ischemic LV dysfunction.
    Results: A total of 23 studies with 10,110 participants met inclusion criteria. Revascularization was significantly associated with lower all-cause mortality and CV mortality compared to OMT. The association was statistically significant regardless of severity of LV dysfunction or method of revascularization. Subgroup analysis demonstrated that revascularization was significantly associated with lower all-cause and CV mortality compared to OMT for patients with viable myocardium and mixed cohorts with variable viability, but not patients without viable myocardium. Revascularization was not associated with a significant difference in risk of heart failure (HF) hospitalization or acute myocardial infarction (AMI) compared to OMT.
    Conclusions: Revascularization in patients with ischemic LV dysfunction is associated with lower risk of all-cause and CV mortality independent of severity of LV dysfunction or method of revascularization. Revascularization is not associated with lower risk of mortality in patients without evidence of viable myocardium and is not associated with lower risk of AMI or HF hospitalization.
