Effect of cumulative uric acid to high-density lipoprotein cholesterol ratio on myocardial infarction in prospective cohorts

Objective: This study aimed to investigate the effect of the ratio of cumUHR on MI, based on the hypothesis that higher exposure to the ratio of cumUHR is associated with a higher risk of MI. Methods: Participants who underwent three examinations between 2006 and 2010 were selected. The cumUHR from baseline to the third check was calculated, multiplying the mean between consecutive checks by the time interval between visits. The association between cumUHR and MI and its progression was evaluated by Cox proportional hazards regression model. The cumulative incidence of endpoint events between cumUHR groups was compared using a log-rank test. Stratification by age, sex, and BMI was further performed. Results: A total of 53,697 people, with an average age of 53.08 years, 78 % of whom were male, with a median follow-up of 10.51 years and 744 myocardial infarction events, were enrolled. The highest cumUHR quartile, MI, had the highest cumulative incidence (log-rank P < 0.01). Multivariate COX regression analysis showed that in the fully adjusted model, there was a high level of concentration in the highest cumUHR quartile (HR, 1.52; 95 % CI, 1.20-1.92) and participants with longer duration of high UHR exposure (HR, 1.55; 95 % CI, 1.22-1.97). Conclusions: The risk of MI increases with cumUHR and is influenced by the time course of cumUHR. In particular, in people aged >= 60 years, males, and BMI < 28 kg/m(2), the risk of MI is more affected by the level of UHR, and more attention should be paid to controlling the level of UHR.
