Mean platelet volume/platelet count ratio predicts long-term mortality in patients with infective endocarditis.

We aimed to examine the association between baseline mean platelet volume/platelet count ratio (MPR) and all-cause mortality in patients with infective endocarditis (IE). This study analyzed 218 consecutive patients with IE and divided them into four groups based on MPR quartiles. We used Kaplan-Meier survival curves to determine the cumulative survival and Cox proportional hazards models to investigate the association between MPR and all-cause mortality after hospital discharge. Kaplan-Meier curves showed a gradual increase in mortality risk from the lowest MPR quartile to the highest quartile. Multivariate analysis revealed that MPR was an independent predictor of increased risk for all-cause death. Elevated MPR was independently associated with long-term all-cause mortality in patients with IE.
