[Late results of minimally invasive operations of myocardial revascularization in patients with acute coronary syndrome].

UNLABELLED: The aim of the study was to compare late results of the minimally invasive operations of myocardial revascularization and conservative treatment in patients with acute ischemic syndrome.

MATERIAL AND

METHODS

Demographic, clinical and echocardiographic data was collected on patients with acute ischemic syndrome; data of 109 patients treated conservatively and data of 26 patients, who underwent minimal invasive operation of myocardial revascularization during acute phase of ischemic syndrome, were compared and ischemic consequences after one-year follow up period were determined in both groups.

RESULTS

The patients of both groups did not differ significantly according to the most clinical characteristics. One third of the patients in the surgery group had previous myocardial infarction, also they had higher rate of paroxysmal atrial fibrillation (26.9% vs 6.4%) and acute left ventricular failure (73.1% vs 44.0%) than the patients without operation. During one-year follow up period there were no cases of lethal events or myocardial infarction in the surgical group, however 37.5% of them had mild angina pectoris. At that time lethal outcome was observed in 6.1%, myocardial infarction in 3.5% and mild-severe angina pectoris in 68.8% of patients.

CONCLUSION

The functional status of the patients significantly improved during one-year period after minimally invasive operation of myocardial revascularization compared to the patients treated conservatively.
