Short- and Long-term Follow-up after Coronary Bypass Grafting for Single-vessel Coronary Artery Disease

Abstract

Short-term outcome and 10-year clinical outcome were reviewed in 114 consecutive patients after coronary artery bypass grafting (CABG) for single-vessel coronary artery disease (CAD). Gated equilibrium radionuclide cineangiography was performed soon after CABG in all cases, and revealed very good early graft patency rates. There was no perioperative mortality, and very low morbidity. During follow-up there were seven late deaths, two from cardiac disease and five from non-cardiac causes. Cumulative survival at 10 years was 93%. Cumulative freedom from additional cardiac invasive procedures was 96%, 93% and 80% at 1, 5, and 10 years, respectively, and cumulative freedom from angina was 93%, 80% and 73%. Conventional single-vessel CABG thus can be safely performed, with minimal postoperative morbidity and no mortality, providing good long-term relief of angina and circumventing need for additional invasive procedures.
