INTRODUCTION. In Cardiac Center of the "Hermanos Ameijeiras" Clinical Surgical Hospital cardiovascular surgery is done from more twenty years ago introducing and developing different techniques of myocardial revascularization. The objective of present research was to describe the results of coronary revascularization over that period. METHODS. A retrospective, longitudinal and descriptive research with five-year cross-sectional cuts was conducted comparing each five-year period with the following one. From the total of 763 patients underwent coronary revascularization from January,1985 to December, 2004, 17 patients were excluded due to missing medical records or with incomplete data and 15 patients operated on without extracorporeal circulation, thus, the universe included 731 patients operated on with this technique. RESULTS. There was predominance the patients aged between 51 and 60years and male sex where smoking and high blood pressure were the more frequent risk factors. The predominant clinical stages were the chronic stable angina and the unstable angina as well as revascularization with three bridges and a trend to rise, as well as the saphenous vein use but with an ascending evolution as the only duct. The time of extracorporeal circulation and anoxic arrest showed a trend to decrease. The more frequent complications were the urinary and respiratory sepsis. There was a decrease of deaths from cardiac causes among which the multiorgan failure and the low cardiac output were the major ones. The low transoperative output decreased but there was a trend to increase during the postoperative one and of the multiorgan failure. CONCLUSIONS. The use of coronary revascularization showed a ascending trend over these 20years mainly in third age patients and of the male sex where the smoking and the high blood pressure were the more associated risk factors. There was predominance of three bridges revascularization and use of saphenous vein but with an increasing use of internal mammary artery. Mortality was a decreasing behavior.
