INTRODUCTION: It is well known that morbid obesity is strongly associated with high blood pressure. Cardiovascular risk reduction is a well studied and described result of bariatric surgery. The objective of this study is to quantify hypertension resolution in patients who underwent bariatric surgery at our institution.
METHODS: We retrospectively reviewed all the patients who underwent either laparoscopic sleeve gastrectomy (LSG) or laparoscopic Roux en Y gastric bypass (LRYGB) at our institution between 2010 and 2015. We selected those patients who were on antihypertensive medical treatment and had a 12-month follow-up. Hypertension resolution was defined as the interruption of any blood pressure medications within the follow-up period. We compared the patients who had resolution of hypertension (group 1) with patients who did not (group 2), based on demographics, comorbidities, and outcomes. Chi-square and student T-test were used for categorical and continuous variables respectively.
RESULTS: Out of 1330 patients, 185 (13.9%) patients met the inclusion criteria, out of which, 73 (39.5%) had a complete resolution of hypertension within 12 months. The patient population included in Group 1 was predominantly female n=114 patients (61.8%), diabetic (n=87, 47%), with a mean BMI of 30.31±4.45 kg/m2, a mean age of 52.6±10.7 years, and a preoperative systolic blood pressure mean of 131±14.31 mmHg. The most common procedure performed was LSG with n=105 (57%).
Comparison between group 1 and group 2 based on age, gender, BMI, and diabetes showed no statistically significant difference. Estimated BMI loss % at 12 months, type of procedure and %EBMIL showed no statistically significant difference between the groups.
CONCLUSIONS: Rapid weight loss is associated with a drastic reduction of blood pressure. Besides weight loss, we did not identify a clear correlation between risk factors when we compared patients who had resolution of hypertension with patients without resolution. Further prospective studies should be done for better understand these findings.
