Resumo

GONZALEZ L., Roberto et al. Early and late results of coronary artery bypass grafting in coronary artery disease in Concepcion, Chile. Rev. méd. Chile [online]. 2018, vol.146, n.12, pp.1395-1404. ISSN 0034-9887.  http://dx.doi.org/10.4067/s0034-98872018001201395.

Background:

Coronary artery bypass grafting (CABG) is the best treatment for a large group of patients with coronary artery disease.

Aim:

To describe early and late results of patients treated with CABG at our Center.

Patients and Methods:

Revision of data bases, surgical protocols and clinical registers of patients operated between January 2006 and December 2008.

Results:

Of 1.003 cardiac surgeries performed during the period, 658 corresponded to isolated CABG (78% in men). The median age of patients was 62 years. Left common coronary artery lesions was found in 135 cases (20%), 555 patients (84%) had hypertension and 231 (35%) were diabetics. Four-hundred thirty (65%) had stable angina and 211 (32%) had a recent myocardial infarction. Twenty-two had left ventricular ejection fraction < 30%. In 248 (38%), a low Additive EuroSCORE risk was found. Emergency surgery was required in 36 (6%) patients. Use of extracorporeal circulation was required in 466 patients (71%). Within 30 days of surgery, complications were recorded in 105 patients (16%) (15 (2%) stroke, 14 (2%) myocardial infarction, 7 (1%) mediastinitis, and in 14 (2%) a reoperation for bleeding). Thirteen patients died (2%). Among the 303 patients with stable angina and preserved left ventricular function, two died (0,7%). Survival at 1, 3 and 5 years was 97,4%, 93,8% y 90,9% respectively. Major adverse cardiac and cerebrovascular events at five years occurred in 20%, stroke in 4%, myocardial infarction in 3% and reintervention in 2%. Seven percent of patients had recurrence of angina.

Conclusions:

We describe a heterogeneous series of patients. The immediate and late results are comparable with international communications.
