RESUMEN
Objective To evaluate the relationship between the Coronary Artery Score (CAS) and pulse pressure index (PPI). Methods Coronary angiography was performed in 711 patients, of whom 470 were male and 241 female, and whose age ranged from 30-82 (61.28?8.44) years. Brachial systolic blood pressure (SBP), diastolic blood pressure (DBP), pulse pressure (pp) and PPI were measured. The severity of coronary artery lesions was analyzed by quantitive computer analysis system (QCA) to acquire CAS. Results Age, sex, BMI, SBP, PP, PPI, Ao, the history of essential hypertention, the history of type 2 diabetes, HDL-C were significantly related to CAS. In a Logistic multivariate analysis, PPI and Ao were significantly related to CAS (?=0.041～0.149, P=0.000). Conclusion PPI and Ao are closely related to CAS. They are predictors for patients with coronary artery disease and the results can be used in clinical indication.
