Trends of Cardiovascular Risk Factors in Patients With Acute Myocardial Infarction: Soroka Acute Myocardial Infarction II (SAMI II) Project

Cardiovascular (CV) patients are becoming older with a greater number of CV risk factors (CVRFs). The Framingham risk score (FRS) includes the major CVRFs and is used for CV risk stratification. We investigated temporal trends in burden of CVRFs among patients with acute myocardial infarction (AMI) throughout a decade. Patients with AMI hospitalized through 2002 to 2012 were studied. The baseline characteristics included age, sex, ethnicity, type of AMI (ST-segment elevation [STEMI] vs non-STEMI [NSTEMI]), coronary artery disease (CAD), diabetes mellitus (DM), dyslipidemia, hypertension, obesity, smoking, and blood lipid profile. The FRS was calculated for each patient. A total of 14 698 AMI admissions were included (age 66.9 ± 13.6 years, 68% males, 47.6% STEMI). Half of admitted cases had ≥4 CVRFs. The mean FRS was 17.1 ± 4.1. Throughout the study period, patients with AMI became older with increased burden of CVRFs. The mean FRS increased from 16.8 ± 4.0 (2002) to 17.3 ± 4.1 (2012; P <.001). Multivariate analysis demonstrated a significant increase in FRS among patients with NSTEMI and significant decrease for patients with STEMI. Conclusions: The last decade, patients with AMI became older with increased burden of CVRFs. Framingham risk score increased among patients with NSTEMI and decreased in patients with STEMI. These trends impact on risk stratification and secondary prevention programs.
