Revascularización coronaria quirúrgica en pacientes con angina inestable aguda / Surgical coronary revascularization in patients with acute unstable angina
A descriptive and cross-sectional study of 122 patients with acute unstable angina, exposed to coronary revascularization surgery at the Cardiovascular Surgery Service in "Saturnino Lora Torres" Teaching Clinical Surgical Provincial Hospital, Santiago de Cuba, was carried out from January, 2007 to the same period of 2014. In the series those patients older than 50 years (68.9 %), those who presented angina in the last 48 hours, type III (66.4 %) and those who presented damage in 3 coronary vessels (47.5 %) prevailed; also, as coronary risk factors, the malesex with a relation of 5,61, the history of hypertension (64.8 %) and the smoking habit (63.1 %) prevailed. Most of the surgical interventions were carried out with the heart beating technique (69.7 %) and as main peroperative complications there were the heart arrhythmias and the low cardiac output; this last one causing the highest number of deaths.
