Analysis of prognostic risk factors in elderly patients with acute coronary syndrome

ABSTRACT

Objective To explore short-term prognosis of patients with acute coronary syndrome (ACS) and prognostic risk factors, and to provide information for prognostic risk assessment. Methods A total of 156 patients with acute coronary syndrome were enrolled. The correlations of baseline characteristics with 30-day improvement, death, angina pectoris and heart failure were analyzed using unordered multivariate logistic regression. Results Logistic regression analysis showed that the independent risk factors for 30-day death included age (OR=1.20, 95%CI 1.07-1.34), diabetes (OR=19.41, 95%CI 3.02-124.70), leukocytosis (OR=11.36, 95%CI 1.87-69.11) and increased platelet (OR=7.72, 95%CI 1.29-46.15). The independent risk factors for 30-day angina pectoris included leukocytosis (OR=2.35, 95%CI 0.89-6.17) and dyslipidemia (OR=6.25, 95%CI 2.11-18.48). The independent risk factors for the occurrence of heart failure during 30-day post-ACS included age (OR=1.10, 95%CI 1.03-1.17), male (OR=4.18, 95%CI 0.81-21.51), leukocytosis (OR=2.97, 95%CI 1.09-8.14) and dyslipidemia (OR=7.69, 95%CI 2.39-24.76). Conclusions Age, diabetes, leukocytosis and increased platelet are independent risk factors associated with 30-day death; Leukocytosis and dyslipidemia are independent risk factors associated with 30-day angina pectoris; Age, male, leukocytosis and dyslipidemia are the independent risk factors associated with 30-day heart failure.
