Acute myocardial infarction mortality in Cuba, 1999-2008.

INTRODUCTION: Acute myocardial infarction is one of the leading causes of death in the world. This is also true in Cuba, where no national-level epidemiologic studies of related mortality have been published in recent years. OBJECTIVE: Describe acute myocardial infarction mortality in Cuba from 1999 through 2008. METHODS: A descriptive study was conducted of persons aged ≥25 years with a diagnosis of acute myocardial infarction from 1999 through 2008. Data were obtained from the Ministry of Public Health's National Statistics Division database for variables: age; sex; site (out of hospital, in hospital or in hospital emergency room) and location (jurisdiction) of death. Proportions, age- and sex-specific rates and age-standardized overall rates per 100,000 population were calculated and compared over time, using the two five-year time frames within the study period. RESULTS: A total of 145,808 persons who had suffered acute myocardial infarction were recorded, 75,512 of whom died, for a case-fatality rate of 51.8% (55.1% in 1999-2003 and 49.7% in 2004-2008). In the first five-year period, mortality was 98.9 per 100,000 population, falling to 81.8 per 100,000 in the second; most affected were people aged ≥75 years and men. Of Cuba's 14 provinces and special municipality, Havana, Havana City and Camagüey provinces, and the Isle of Youth Special Municipality showed the highest mortality; Holguín, Ciego de Ávila and Granma provinces the lowest. Out-of-hospital deaths accounted for the greatest proportion of deaths in both five-year periods (54.8% and 59.2% in 1999-2003 and 2004-2008, respectively). CONCLUSIONS: Although risk of death from acute myocardial infarction decreased through the study period, it remains a major health problem in Cuba. A national acute myocardial infarction case registry is needed. Also required is further research to help elucidate possible causes of Cuba's high acute myocardial infarction mortality: cardiovascular risk studies, studies of out-of-hospital mortality and quality of care assessments for these patients.

Cardiovascular Risk among Older Women in a Havana Health Area.

UNLABELLED: Introduction Cardiovascular morbidity and mortality increase in women after menopause. Various scoring models assess qualitative risk of cardiovascular disease. The Framingham Heart Study global risk score is among the most widely used. Objective Determine level of coronary heart disease risk among women aged ≥60 years in a Havana health catchment area (geographic area whose residents are served by the M�rtires del Corynthia Polyclinic, in the Plaza de la Revoluci�n municipality of Havana). Methods A descriptive, cross-sectional study was conducted in 2006. Universe: all women (3,396) aged ≥60 years in the catchment area, attended at the primary care level by the Polyclinic and 42 neighborhood family doctor-and-nurse offices. Equal probability sample: 1,082 women meeting the inclusion criteria, chosen through single-stage cluster sampling considering a <10% error margin for estimates for this parameter, a 95% confidence interval (CI) and a design effect of 1.5. Absolute frequencies and percentages were calculated to summarize the qualitative data obtained. Results were presented as tables. Results The most common cardiovascular risk factors found in this study were: physical inactivity, 74.9%; hypertension (HTN), 70.6%; abdominal obesity, 53%; reported family history of coronary heart disease (CHD), 41.8%; diabetes mellitus (DM), 21.8%; and cigarette smoking, 17.2%. Scoring according to number of risk factors present in each individual, 79.3% of these women fell into the high- or moderate-risk categories. Conclusion The large number of women categorized as high- or moderate-risk for coronary heart disease in this population emphasizes the need for preventive actions aimed at reducing these figures.
