Abstract

To evaluate the duration of favourable effects of coronary artery bypass (CAB) on exercise-induced angina (A), 58 patients: 13 with single, 21 with double and 24 with triple vessel disease, were studied. All patients underwent CAB for stable angina on effort. Patients underwent exercise testing (ET) before surgery and 1, 2 and 3 years after. Heart rate peak (HR), HR x systolic blood pressure peak (DP), work load (W), exercise-induced ST segment depression (ST) and incidence of A were evaluated; the results of ET before surgery were compared with those found after CAB. The findings show that HR, DP, W and ST were significantly improved after surgery for at least 3 years. The lowest incidence of A was found at one year ET (20.6%), while it increased at 2 years (27.5%) and 3 years ET (37.9%). Most patients with A had angiographic evidence of left ventricular abnormal wall motion and ECG signs of previous myocardial infarction. The data indicate that serial exercise testing can objectively monitor the results of CAB. Most patients show an improved exercise tolerance for up to 3 years after CAB. Some patients, with more severe CAD, showed a progressive deterioration of the clinical pattern and a decrease of exercise tolerance.
