Prevalencia de hiperreactividad cardiovascular en personas con presión arterial normal del área urbana del municipio de Cienfuegos

摘要

Background: cardiovascular hyperactivity is a marker of cardiovascular risk. Nevertheless, its prevalence in the population is not well known. Objective: to describe the prevalence of cardiovascular hyperreactivity in individuals with normal blood pressure in the population of the urban area in the municipality of Cienfuegos. Methods : a cross-sectional and descriptive study was performed. The sample consisted of 859 normotensive individuals who were applied the sustained weight test. The variables studied were age, sex, skin color, educational level, marital status and related cardiovascular hyperreactivity: systolic pressure, diastolic pressure, average arterial pressure, differential pressure and cardiovascular reactivity index. Their relative frequencies trusts intervals. We determined the prevalence ratio interval with a confidence interval of 95 %. In some cases Pearson’s Chi square test was performed with a significance level of 95 %. Results: the prevalence of cardiovascular hyperreactivity was 45,1 % (9 5% CI 41,8-48,5). There was a prevalence ratio of 1,44 (95 % CI 1,2-1,6) times higher in men in relation to women. 44,5 % of white skinned individuals and 46,8 % of black skinned individuals presented cardiovascular hyperreactivity as well as 52,8 % of those with more than 40 years and only 38,1 % in ages under this level. Conclusions: the prevalence of cardiovascular hyperreactivity is high and even higher in men, obese individuals and in those older than 40 years.
