Analysis of 73,555 participants across four major cohorts reveals that changes in handgrip strength over time predict cardiovascular disease risk more accurately than baseline measurements alone. Each standard deviation decrease in grip strength slope increased CVD risk by 19.8%, while cumulative grip strength decline elevated risk by up to 44%. Participants who maintained or increased grip strength during follow-up showed reduced cardiovascular risk compared to those experiencing decline. The predictive accuracy improved by up to 7.6% when dynamic grip strength metrics were incorporated into risk models, with stronger associations observed in East Asian populations compared to Europeans. This finding represents a significant advancement in cardiovascular risk assessment, suggesting that monitoring grip strength trajectories could enhance preventive care strategies. The research addresses a critical gap in existing literature, which previously focused only on single-time grip strength measurements. However, as this is a preprint awaiting peer review, these promising results require validation through the formal review process. The implications are substantial for clinical practice, potentially transforming how healthcare providers assess and monitor cardiovascular risk using this simple, cost-effective measurement tool.
