Introduction:

Coronary disease is the main cause for heart failure in the world. However, the option of revascularization is often denied to patients with severe ventricular dysfunction.

Motivation:

To describe clinical characteristics and mortality after 1 and 6 months of patients with an ejection fraction less than or equal to 35% who underwent coronary revascularization in a Colombian reference centre.

Methods:

Retrospective, descriptive, observational study.

Results:

1133 patients who had surgery between January 2009 and 2013 were included, of whom 77 had ventricular ejection fraction of less than or equal to 35%. Average age was of 63 years (37-82). Average ejection fraction was 31% (15-35%). Registered end-diastolic diameter averaged 30.2 (22.1-39.2). Indication for revascularization was acute myocardial infarction in 75.6% and chronic heart failure in 24% of the cases. 30-day mortality rate was 8.1% and 6- month mortality was 13.5%. Improvement of ventricular ejection fraction was seen on 81% of the patients. Myocardial viability assessment before revascularization was conducted in only 5 cases (6.6%).

Conclusions:

This study suggests that the prognosis of patients with severe systolic dysfunction who undergo revascularization surgery is similar to other studies and additionally helps improve ejection fraction.
