Abstract

Studies on the association between leptospirosis and acute coronary syndrome (ACS) are lacking. Therefore, this study identifies the effects of leptospirosis on the risks of developing ACS with a nationwide retrospective cohort study. We identified adult patients aged ≥20 years who were newly diagnosed with leptospirosis. We also randomly selected a comparison cohort from the general population by using a propensity score matching method. We analyzed the risks of ACS by using Cox proportional hazard regression models. Among the 23.74 million people in the cohort, 3690 patients with leptospirosis (68% men, mean age of 52.2 years) and 3690 controls were followed for 13,677 and 15,652 person-years, respectively. The overall incidence of ACS was higher in the leptospirosis cohort than in the nonleptospirosis cohort (4.68 vs 3.71 per 1000 person-years), with a hazard ratio (HR) of 1.69 (95% confidence interval [CI]=1.12-2.56). Men exhibited a 1.88-fold greater HR of ACS than women did (95% CI=1.20-2.94). The risk of developing ACS was highest for leptospirosis patients aged ≥65 years (HR=7, 51% CI=4.35-12.9) compared with patients aged ≤49 years. Leptospirosis is not a previously identified risk factor for ACS. The findings of this ...Continue Reading

Cardiovascular Disease Pathophysiology

Cardiovascular disease involves several different processes that contribute to the pathological mechanism, including hyperglycemia, inflammation, atherosclerosis, hypertension and more. Vasculature stability plays a critical role in the development of the disease. Discover the latest research on cardiovascular disease pathophysiology here.
