Surgical revascularization in the ischemic heart disease. Long-term results in a series of consecutive patients selected according to the principles.
OBJECTIVE
Ischemic heart disease can be treated with drugs, percutaneous coronary interventions (PCI) and surgical revascularization (CABG). In our institution the therapeutic decisions for non emergent cases have been regularly taken during a daily meeting attended by clinicians, interventionalists, and surgeons, who all adhere to the principles of Evidence Based Medicine. The purpose of the present report is to investigate the long-term results in a series of consecutive patients to whom surgical revascularization has been recommended following the abovementioned approach.


METHODS
We selected 597 patients with no prior interventions, who were referred to our institution for coronary angiography between January 1991 and December 1997 and to whom surgical revascularization was recommended. The Kaplan-Meier method was adopted to evaluate survival and freedom from: non fatal acute myocardial infarction, PCI, repeat CABG.


RESULTS
The results were compared to those of the randomized trials or of large follow-up reports. The mean observation period was 6.8 years. The results at 5 and 10 years were: overall survival 95.5% and 90.2%; freedom from acute myocardial infarction 95.5% and 90.2%; freedom from surgical reintervention 98.6% and 97.1%; freedom from PCI 91.2% and 79.8%; survival free from all events 79.3% and 58.1%. These rates were comparable to those reported by the most important clinical trials.


CONCLUSIONS
If surgical treatment for patient with coronary artery disease is recommended according to the suggestions of the leading clinical trials and pertinent guidelines, the results in terms of mortality and morbidity are comparable to those of the trials themselves, even in the non selected patients of daily clinical practice.
