Resumen

MARTINEZ MUNIZ, Juan Oscar et al. Coronary revascularization with beating heart in the acute coronary syndromes. MEDISAN [online]. 2011, vol.15, n.7, pp.916-924. ISSN 1029-3019.

A descriptive and prospective study of the 89 surgically treated patients who presented acute coronary syndrome was carried out during a 6 years period in the Cardiocenter from Santiago de Cuba. The case material, whose patients had a mean age of 59 years-old, comprised those who suffered from unstable angina (80,9 %), as well as those that presented lesions of 3 vessels and trunk of the left coronary artery. In 87,6 % interventions were carried out with the heart beating without extracorporeal circulation and the average of bridges per patient was of 2,8. Among the complications taking place in 32,6 % of the series arrhythmias, the ischemic changes of the ST segment and the low cardiac output prevailed. The preoperative ejection fraction of the left ventricle below 50 %, the distal "bad" channels and the endarterectomy influenced negatively on the global mortality of 8,9 %.
