Off-pump multivessel coronary artery surgery in patients with acute myocardial infarction / 中华胸心血管外科杂志

ABSTRACT

Objective To study the feasibility and clinical experience of off-pump multivessel coronary artery bypass grafting (OPCAB) for patients with acute myocardial infarction (AMI). Methods Sixty-one patients with AMI were treated surgically. The mean age of was (64.7?7.2) years. The last attack angina pectoris unreliable with use of Nitro-Glycerine, and the levels of CK-MB documented (3.5?1.8) times and TnI were (10.9?4.1) times higher than the normal. OPCAB was performed in sixty-one patients and in two patients, converted to cardiopulmonary bypass. All patients were followed up from twelve months to twenty-four months. Results The mean interval between the onset of AMI and the accomplishment of OPCAB was (115.8?15.1) hours ,and the number of distal anastomosis was (3.4?0.7)/pt. The mortality rate was 3.28%. During the period of follow-up, all patients were asymptomatic and the results of echocardiography showed the function of ventricles improved. Conclusion Off-pump technique applying to multivessel coronary artery disease with AMI yielded satisfied clinical outcome. The morbidity and mortality of OPCAB is substantially lower maybe due to avoiding the adverse effects of CPB.
