RÉSUMÉ
Objective To determine the lesion characteristics and effect of intervention on diseased grafts in older patients. Methods Thirty-eight patients with angina after coronary artery bypass grafts (CABG) were enrolled into Nanjing First Hospital. Interventions were performed after multiple-view angiogram and formal consent from relatives received. Angiographic follow-up was conducted within 6 months. Cardiac events were recorded during the 6-month clinical follow-up. Results Of the 38 patients (36 males and 2 females), the average age was 63.2 years. Angina occurred 11.5 months after CABG. Angipgrams were performed 4.8 years after CABG. Diabetes was complicated in 10 cases and old myocardial infarction in 8, respectively. Left ventricular ejection fraction was increased from 52%?10% to 58%?14% (P
