Abstract The impact of sodium-glucose co-transporter 2 inhibitors (SGLT2-i) on reducing the risk of all-cause mortality and rehospitalization for heart failure (HF) in patients with acute myocardial infarction (AMI) remains unclear. This study aims to evaluate the effect of SGLT2-i on all-cause mortality and rehospitalization for HF in patients diagnosed with AMI. A comprehensive search was conducted in PubMed, Web of Science, the Cochrane Library, and Embase for relevant studies published up to May 2024, following the PICOS principle. Eligible studies included randomized clinical trials and cohort studies comparing SGLT2-i with placebo regarding all-cause mortality, rehospitalization for HF, cardiovascular mortality, and the incidence of nonfatal MI in AMI patients. Patient-level data from each trial were synthesized into a pooled dataset and analyzed using a mixed-effects or random-effects model based on the I2 statistic. Ten clinical trials enrolling 15,748 participants (6913 in the SGLT2-i group and 8835 in the placebo group) were included. The follow-up duration ranged from 12 weeks to 2.1 years. SGLT2-i significantly reduced rehospitalization for HF (RR: 0.69, 95% CI 0.60–0.81, P

Abstract Objective We aimed to assess the effect of SGLT2i on arrhythmias by conducting a meta-analysis using data from randomized controlled trials(RCTs). Background Sodium-glucose co-transporter 2 inhibitors (SGLT2i) have shown cardioprotective effects via multiple mechanisms that may also contribute to decrease arrhythmias risk. Methods We searched in databases (PubMed, Embase, Cochrane Library, and clinicaltrials.gov) up to April 2023. RCTs comparing SGLT2i with placebo were included. The effects of SGLT2i on atrial fibrillation(AF), atrial flutter(AFL), composite AF/AFL, ventricular fibrillation(VF), ventricular tachycardia(VT), ventricular extrasystoles(VES), sudden cardiac death(SCD) and composite VF/VT/SCD were evaluated. Results 33 placebo-controlled RCTs were included, comprising 88,098 patients (48,585 in SGLT2i vs. 39,513 in placebo). The mean age was 64.9 ± 9.4 years, 63.0% were male. The mean follow-up was 1.4 ± 1.1 years. The pooled-results showed that SGLT2i was associated with a significantly lower risk of AF [risk ratio(RR): 0.88, 95% confidence interval(CI) 0.78–1.00, P = 0.04] and composite AF/AFL (RR: 0.86, 95%CI 0.77–0.96, P = 0.01). This favorable effect appeared to be substantially pronounced in patients with HFrEF, male gender, dapagliflozin, and > 1 year follow-up. For SCD, only in heart failure patients, SGLT2i were found to be associated with a borderline lower risk of SCD (RR: 0.67, P = 0.05). No significant effects of SGLT2i on other ventricular arrhythmic outcomes were found. Conclusions SGLT2i lowers the risks of AF and AF/AFL, and this favorable effect appeared to be particularly pronounced in patients with HFrEF, male gender, dapagliflozin, and longer follow-up (> 1 year). SGLT2i lowers the risk of SCD only in heart failure patients. Graphical Abstract

Conclusions: AF is not only an isolated disease with abnormal electrophysiological activity but might also share a common genetic basis and biological process with tumors and inflammatory diseases as well as cardiovascular diseases. Moreover, the six novel genes inferred from network analysis might help detect the missing AF risk loci.

Objective: This study was aimed at investigating factors influencing the progression of native coronary atherosclerosis after percutaneous coronary intervention (PCI). Methods: A cohort of 462 patients was classified into progressive (n = 73) or non-progressive (n = 389) groups according to the presence of native coronary atherosclerosis progression on coronary angiography. Clinical data and angiography results were compared during follow-up, and the time to progression of native coronary atherosclerosis was recorded. Subsequently, multivariate Cox regression analysis was conducted. Results: In comparison to the non-progressive group, the progressive group had higher levels of glycosylated hemoglobin (HbA1c) and triglycerides (TG), and higher scores on the Synergy Between PCI with Taxus and Cardiac Surgery (SYNTAX) scale, but lower levels of high-density lipoprotein cholesterol. Moreover, the rates of hyperuricemia and acute coronary syndrome (ACS) were higher in the progressive group than the non-progressive group. Multivariate analysis identified ACS, HbA1c level ≥6.5%, TG level ≥5.6 mmol/L, and SYNTAX score ≥23 as risk factors for the progression of native coronary atherosclerosis. Conclusion: ACS, elevated HbA1c and TG levels, and higher SYNTAX scores may be associated with the progression of native coronary atherosclerosis after PCI.
