Prevalencia de la insuficiencia de la válvula mitral en pacientes mayores de 30 años con fallo cardiaco atendidos en el servicio de cardiología del Hospital Teodoro Maldonado Carbo entre el año 2016 y 2019.

Abstract

Introduction: Mitral regurgitation drives adverse cardiac remodeling in patients with heart failure, which structurally affects the heart, causing deficits in its functions. The there are no studies that show whether it is a frequent complication to keep it in mind at the time of evaluation of the patient with heart failure. Objective: To determine the prevalence of mitral valve regurgitation in patients over 30 years of age with heart failure treated in the cardiology service of the Teodoro Maldonado Carbo Specialty Hospital in the period 2016-2019. Materials and methods: A prevalence study was carried out, and the information was obtained through the medical records of the patients who were treated in the cardiology service at the Teodoro Maldonado Carbo Specialties Hospital in the period 2016-2019. The data that were investigated were sex, personal history, etiology, mechanisms of mitral regurgitation, degrees of severity, NYHA classification, and ejection fraction. Results: The prevalence of mitral regurgitation was 5.65%, it was made up of 208 patients with mitral regurgitation out of 3678 patients with heart failure. Functional etiology, global hypokinesia as a specific mechanism, NYHA class III, and severe grade were the most frequent characteristics found in patients with mitral regurgitation. Conclusions: It was determined that mitral regurgitation is not a frequent complication in patients with heart failure.
