Risk factors for left ventricular remodeling after myocardial infarction: A meta-analysis.

Background: This study aimed to assess potential risk factors for left ventricular remodeling (LVR) after acute myocardial infarction (MI).

Methods: We systematically searched PubMed, the Cochrane Library, MEDLINE, Embase, Web of Science databases CNKI Scholar, VIP, and WanFang databases for all relevant epidemiological studies published up to August 1, 2023. Fixed-effects model or random-effects model was employed to pool the study-specific effect sizes and 95% confidence intervals (CIs).

Results: Fifteen studies with a total of 3,093,792 participants were included according to inclusion criteria. Major modifiable risk factors associated with LVR after MI were diabetes (odds ratio [OR] = 2.053, 95% CI: 1.504-2.803), MI site (OR = 2.423, 95% CI: 1.584-3.708), cystatin C (OR = 6.204, 95% CI: 1.830-21.036), B-type natriuretic peptide (OR = 2.280, 95% CI: 1.466-3.546), as well as creatine kinase-myocardial band (OR = 1.013, 95% CI: 0.985-1.042).

Conclusion: The current study provides evidence indicating that diabetes, the site of MI, cystatin C, B-type natriuretic peptide, and creatine kinase-myocardial band are the primary risk factors for LVR after MI. Recognizing and addressing these modifiable risk factors is crucial for the development of effective preventive and treatment strategies.
