RODRIGUEZ PERON, José Miguel et al. Utilización de un índice pronóstico de morbilidad y mortalidad por enfermedad cardiovascular asociada con factores de riesgo aterogénico. Rev Cub Med Mil [online]. 2002, vol.31, n.2, pp.87-93. ISSN 0138-6557.

An analytical-observational case-control study was carried out to assess the impact of some atherogenic risk factors on morbidity and mortality from cardiovascular disease and to set a synthetic indicator for stratifying risk groups of vasculovisceral damage on the basis of such factors. The sample was made up of 200 patients randomly selected from patients admitted at "Dr Luis Díaz Soto" Higher Institute of Military Medicine throughout the year 2000. Patients with unequivocal diagnosis of cardiovascular disease were classified as sick people whereas patients with similar characteristics without vasculo-visceral damage were taken as controls. When making the statistical significance analysis, the risk factors related with morbidity and mortality from cardiovascular disease, with independent predictive power, were the following (in decreasing order of odd ratios (OR): blood hypertension, hypercholesterolemia, diabetes mellitus, lack of physical exercising and smoking. Stress, body mass index and personal and family pathological history did not show significant differences. These variables integrated into a synthetic scoring were stratified and compared, and cases showed significant differences with respect to controls. The estimated probabilities of getting sick was 6.9 times higher in the group of exposed people (strata 2 and 3). This was a preliminary proof of the discriminating value of the prognostic index for the stratification of population by risk groups since such an index may be an adequate alternative due to its simplicity, cost-benefit relation and advantages for the implementation of intervention strategies at primary health care level against non-communicable chronic diseases.

Keywords : CASE-CONTROL STUDIES; INDICATORS OF MORBIDITY AND MORTALITY; CARDIOVASCULAR DISEASES; RISK FACTORS.
