- Cardiac Remodeling Patterns in Severe Obesity According to Arterial Hypertension Grade(2018) CLEVA, Roberto de; ARAUJO, Victor Arrais; BUCHALLA, Carla Cristina Ornelas; COSTA, Fabio de Oliveira; CARDOSO, Acacio Fernandes; PAJECKI, Denis; SANTO, Marco AurelioThe purpose of this study is to correlate the left ventricular hypertrophy (LVH) patterns according to severe obesity and arterial hypertension (AHT) grades. A cross-sectional prospective study was conducted in 379 patients with severe obesity. Obesity was classified according to the BMI in the following: morbidly obese (MO; 40 < BMI < 50 kg/m(2)) and super obese (SO; BMI > 50 kg/m(2)). The AHT was classified into classes 1 and 2 according to American Heart Association. The presence of LVH and the pattern of cardiac remodeling were determined by transthoracic echocardiography. LVH was present in 58.6% of patients. Obesity and AHT had additive effects in LVH prevalence. LVH was found in 32.9 and 46.7% of MO with AHT grades 1 and 2, respectively. LVH was diagnosed in 39.1% in SO with AHT grade 1 and in 50% of AHT grade 2. Patients with AHT presented a significantly higher risk of developing LVH (OR 1.97; p = 0.003). Hypertension grade was also a determinant variable in the development of LVH. Patients with AHT 2 had 4.31-fold greater risk (p < 0.001) when compared to normotensive patients. BMI was only considered an independent risk factor for LVH in patients with BMI greater than 47.17 kg/m(2) (OR 1.62; p = 0.023). AHT is a stronger predictive factor of LVH than obesity grade.
