The relationship between left ventricular mass index and body composition in new-diagnosed hypertensive patients

BACKGROUND: Cardiovascular disease (CVD) is considered a public health burden and most common cause of mortality in all over the world. The latency time for developing CVD may be several decades. the objective of this study was to examine the relationship between body composition and Left Ventriculare Mass Index (LVMI) in newly diognosed hypertensive patients. METHODS: We enrolled 120 new-diagnosed hypertensive patients (mean age 45 ± 8 years) who admitted to our nephrology clinic. Body fat percentage (BFP) was measured by bioelectrical impedance (BIA). Echocardiography examinations were performed for all patients. RESULTS: Mean values of Waist hip ratio, Body mass ındex, Body fat percentage, Systolic blood pressure, Diastolic blood pressure were significantly higher for females than males (all p values <0.05). The female patients had higher LVMI than male patients (94.8 ± 13.1 vs 89.2 ± 14.6, p < 0.05). The study patients were divided into 3 groups according to their BFP defined by BIA. Group 3 patients, who exhibited higher body fat, had significantly higher BMI (p < 0,05), total leukocyte count (p < 0.05), CRP (p < 0.05), triglyceride (p < 0.05), and female predominance. Group 3 patients were statistically older than group 1 patients (46.2 vs. 40.6 years, p < 0.05). Additionally, LVMI levels were higher in Group 3 than Group 1 (p < 0.05) (Table 3). In logistic regression analysis, independent factors affecting LVMI were age, weight, gender and BFP (all p values were <0.05). CONCLUSIONS: BFP was associated with higher LVMI, in newly diognosed hypertensive patients. Its use results in significantly lower proportions of individuals with LVH in the population, in particular among hypertensive and the obese patients.
