Factors related to the in-hospital course of acute coronary syndrome

Abstract

Introduction: The advent of new invasive coronary intervention strategies has led to a worldwide reduction in morbidity and in-hospital mortality from acute coronary syndrome. However, these indicators have had some variations in the Provincial Department of Cardiology of Sancti Spiritus.

Objective: To determine the clinical and epidemiological factors associated with in-hospital course of patients admitted with this diagnosis.
Method: An observational, descriptive, and retrospective research was carried out at the Department of Cardiology at Camilo Cienfuegos General Provincial Hospital in 2011. The sample consisted of 363 patients admitted with some clinical forms of acute ischemic heart disease. The frequency distribution according to clinical and epidemiological variables were calculated by statistical significance tests (Chi square, logistic regression, beta exponential), which allowed to establish relations with the different variables and mortality.
Results: The most frequent complications were: acute left ventricular dysfunction, ventricular arrhythmias and post-infarction angina. Prior topography infarction, history of previous infarction, hypertension and smoking were the variables that related the most with mechanical complications and recurrent stroke. The longest demurrage was motivated by postinfarction angina, reinfarction and cardiogenic shock.
Conclusions: There was a decrease in hospital mortality from acute coronary syndrome in 2011 although there was a high incidence of mechanical and arrhythmic complications which motivated a longer stay at the Department of Cardiology.
