Abstract
BACKGROUND
Muscular strength has been linked to increased risk of cardiovascular disease in the community population. The aim of this systematic review and meta-analysis is to evaluate the association between weak handgrip strength (HGS) and mortality risk in patients with coronary artery disease (CAD).
METHODS
To carry out the meta-analysis, an extensive search was conducted on databases such as PubMed, Embase, Web of Science, Cochrane Library, Wanfang, and CNKI to identify observational studies with longitudinal follow-up. Random-effects models were used to combine the findings, taking into account the potential influence of heterogeneity.
RESULTS
Eight observational studies involving 10 543 patients with CAD were included. During a mean follow-up duration of 20.4 months, 1327 (12.6%) patients died. Pooled results showed that weak HGS at baseline was associated with an increased risk of all-cause mortality during follow-up (risk ratio [RR]: 1.95, 95% confidence interval: 1.50 to 2.55, p < 0.001; I2 = 62%). Subgroup analysis suggested a stronger association between weak HGS and increased mortality in older patients with CAD as compared to that of overall adult patients with CAD (RR: 3.01 vs. 1.60, p for subgroup difference = 0.004). Subgroup analyses according to study location, design, subtype of CAD, follow-up duration, analytical model, and study quality scores showed similar results (p for subgroup difference all > 0.05).
CONCLUSIONS
Weak HGS at baseline is associated with an increased risk of mortality in patients with CAD, particularly in older patients with CAD.
