Registro hospitalario de infarto agudo de miocardio en Santa Clara 2007-2008 / Hospital registry of acute miocardial infarction in Santa Clara

RESUMEN

Introduction and objectives: In Cuba, the vital statistics of morbi-mortality due to acute myocardial infarction come from small health areas. The objective of this study was to identify the main characteristics and hospital management of patients with myocardial infarction, through a hospital registry of infarctions. Methods: The cases of acute myocardial infarction in patients between 45 and 74 years of age, from Santa Clara, during 2007 and 2008, were monitored. The information sources were hospital discharge records, hospital registry of myocardial infarction, death certificates and nosocomial autopsy records. The MONICA methodology was used (Monitoring Trends and Determinants in Cardiovascular Disease Project). Results: a total of 297 patients with acute myocardial infarction were registered; 62,7 percent of males and 46,8 percent of women received reperfusion treatment. The hospital deaths in males and women were 25,3 percent and 45 percent respectively. The variables related to a higher mortality were age, female sex, a high cardiac frequency, anterior-wall infarction, a high creatinine level, as well as individual antecedents of ischemic heart disease and diabetes mellitus. On the other hand, the treatments with fibrinolitics and/or beta-blockers were inversely proportional to mortality. Conclusions: There was a high prevalence of unknown dyslipidemia and hospital death within 28 days; as well as little use of invasive strategies. Systolic hypertension at the time of admission was related with a better prognosis(AU)
