BACKGROUND: This study compares early results of left anterior descending coronary artery stenting using drug-eluting stents (Cypher) with off-pump coronary artery bypass grafting (OPCAB).

METHODS: From June 2002 to June 2003, 386 consecutive patients underwent myocardial revascularization of the left anterior descending coronary artery territory, 130 by Cypher and 256 by OPCAB. After matching for age, sex, and extent of coronary artery disease, two groups (each with 94 patients) were used to compare the two revascularization modalities. The two groups were similar; however, old myocardial infarction and intraaortic balloon pump were more prevalent in the OPCAB group, and prior percutaneous transluminal coronary angioplasty was more prevalent in the Cypher group.

RESULTS: The number of coronary vessels treated per patient in the two groups was similar (1.54 versus 1.34, OPCAB and Cypher, respectively; not significant). Mean follow-up was 18 months. Thirty-day mortality was 1% in the OPCAB group and 0% in the Cypher group. There was one late death in each group. Angina returned in 31% of the Cypher group and in 11% of the OPCAB group (p = 0.001). There were nine reinterventions in the Cypher group: seven coronary angioplasties (including two to the left anterior descending coronary artery) and two surgical interventions. There were two reinterventions (percutaneous transluminal coronary angioplasty) in the surgical group (p = 0.042).

CONCLUSIONS: Despite the higher risk profile of patients treated with OPCAB, their clinical outcome is better. A longer and more complete angiographic follow-up is required to determine the role of drug-eluting stents in left anterior descending coronary artery revascularization.
