Life adaptation after percutaneous transluminal coronary angioplasty and coronary artery bypass grafting.

Life adaptation of 32 patients who had undergone percutaneous transluminal coronary angioplasty (PTCA) for coronary stenosis was compared with that of 15 patients who had coronary artery bypass grafting (CABG). Patients were matched for psychosocial, anatomic and cardiac functions. Life adaptation was measured at 6 and 15 months after PTCA or CABG by the Psychosocial Adjustment to Illness Scale (PAIS), a multidimensional instrument that evaluates change in 7 primary life domains. The overall PAIS scores for patients who had undergone PTCA were significantly better (p less than 0.04) than the scores for those who had undergone CABG after 6 months, and this superior functioning continued after 15 months (p less than 0.05). After 6 months patients who had undergone PTCA functioned better at work (p less than 0.005), in sexual performance (p less than 0.0001) and with their families (p less than 0.002). The improvement in work functioning continued at 15 months (p less than 0.04), but the differences in sexual and family domains became nonsignificant.
