Prevalência da hipertrofia ventricular esquerda em pacientes hipertensos no município de Chapecó-SC

Abstract

Left Ventricular Hypertrophy (LVH) is a common target organ damage in patients with Systemic Arterial Hypertension (SAH) and is associated with an increased cardiovascular risk. The SAH is a public health problem due to its high prevalence and inadequate control. However, the magnitude of LVH in hypertensive patients in the city of Chapecó is uncertain. This is a prospective cross-sectional study that included 40 patients seen at a referral clinic in the city. The myocardial structure of the left ventricle was assessed by means of two-dimensional transthoracic echocardiography and the prevalence of LVH in patients using antihypertensive therapy was verified, as well as the relationship of the results of the examination to the variables age, sex, Body Mass Index ( BMI) and smoking. In this study, p <0.05 was considered statistically significant. Results and Conclusions: There was a prevalence of 58.3% of concentric LVH and 19.4% of concentric remodeling of the left ventricle, values above the average of previous studies in outpatients. The mean LVMI in g / m² among the women surveyed was 94.47, while among men it was 102.4. Only 17.5% did not show an increase in left ventricular mass or wall thickness. We recommend carrying out new studies that justify the high prevalence of LVH in our community.
