ABSTRACT

Introduction: The natural evolution of heart failure, in the context of acute coronary syndrome, is the progressive appearance of symptoms and signs that produce a decline in vital capacity and, finally, death.
Objective: To determine the echocardiographic risk factors associated with adverse events in patients with heart failure and acute coronary syndrome.
Methods: An observational and analytical study of a 1: 5 case-control type was carried out with 66 patients who had acute heart failure and acute coronary syndrome, and who were treated at Dr. Ernesto Guevara de la Serna General Teaching Hospital, in Las Tunas, from January 2, 2017 to March 30, 2018. The variables analyzed were left ventricular ejection fraction, degree of left ventricular diastolic dysfunction, left atrial volume, area of the left atrium, E/eꞌ ratio measured in the septal ring of the left ventricle, velocity of the S wave in the tissue doppler and measurements of the left ventricle. Descriptive statistics and bivariate analysis were used.
Results: The reduced ejection fraction was the most frequent echocardiographic finding for the group of "cases" (81.8%), followed by the area increase and volume of the left atrium. The restrictive filling pattern was the echocardiographic determination that was most associated with the occurrence of adverse events (OR 22.08, p= 0.000), followed by elevated left atrial volume and reduced left ventricular ejection fraction. In relation to the measurements of the left ventricle, only the end volumes of diastole and high systole showed good associations.
Conclusions: The restrictive filling pattern, the increased left atrial volume, the frankly high E/e´ ratio higher than 15 and the low S wave velocities can be potential predictors of adverse events in this type of patients.
