Abstract:
Objective To analyze clinical characteristics in young and aged patients with coronary artery disease (CAD).Methods The clinical and coronary angiographic data were compared between young (PCAD, male <55 years old, n =74, female <65 years old, n =71 ) and aged (CAD, male >55 years old, n = 106, female > 65 years old, n = 111 ) patients.Seventy-one patients excluded with CAD by angiography served as controls (non-CAD).The traditional risk factors (including age, smoking, blood pressure, lipid profile, blood glucose, BMI, family history), coronary angiographic changes were analyzed and compared among various groups.Results (1) Compared with CAD group, PCAD patients had significantly higher rate of smoking ( 50.3% vs.38.0%, P < 0.05 ), significantly higher positive CAD family history rate (29.7% vs.19.9% ,P <0.05) and significantly higher TG level [ (2.13 ± 1.89) mmol/L vs.( 1.78 ± 1.14) mmol/L, P < 0.05 ], while had significantly fewer traditional risk factors (2.50 ± 1.28 vs.2.76 ± 1.43, P < 0.05 ) and lower hypertension rate (59.3% vs.73.3%, P < 0.05 ).There were significantly more PCAD patients with acute coronary syndrome ( 66.2% vs.42.6%, P < 0.05), more PCAD patients had single vessel lesion (51.0% vs.30.4% ,P <0.05), lower average lesion score (4.86±2.30 vs.5.92±2.66,P <0.05).(2) The logistic regression results showed that positive CAD family history ( P = 0.029, OR = 1.766,95% CI 1.060-2.940 ) and smoking ( P = 0.066, OR = 1.561,95% CI 0.971-2.510) are important independent risk factors for the development of PCAD.Conclusions Smoking, positive family history and the increased TG might contribute to the pathogenesis of PCAD.
