INTRODUCTION: Although several studies have addressed the improvement of hypertension (HTN) after bariatric surgery, only a few of them specifically addressed the effects of the procedures on uncontrolled/resistant HTN. The aim of our study is to assess the remission of uncontrolled/resistant hypertension and its impact in the risk of cardiovascular disease (CVD) of morbidly obese patients following laparoscopic bariatric procedures.
METHODS: We retrospectively reviewed all patients who underwent Laparoscopic Bariatric surgery at our institution from 2010-2014. We used the guidelines of the American College of Cardiology (ACC) to define HTN and uncontrolled/resistant hypertension. Only patients who met the criteria for the ACC and the calculation of the Framingham-BMI 10-year risk score pre-operatively at 3 months and at 12 months follow-up were included.
RESULTS: Of the 1,200 patients reviewed, 203(16.91%) met the required criteria of uncontrolled/resistant HTN according to the ACC and had the required variables for the risk assessment of CVD using the Framingham-BMI 10-year risk score. The most prevalent procedure was Laparoscopic sleeve gastrectomy LSG n=133 (65.51%). The most significant improvement found was an amelioration of 15mmhg and 13mmgh when comparing of systolic blood pressure pre-operatively, at 3 and 12 months follow-up respectively(P=0.0001). The improvement in the risk of CVD is shown by an absolute risk reduction(ARR) of 14% at 3 months and 15% at 12 months follow-up, both evidencing statistically significant (P=0.0001) In the patients with resistant hypertension the mean heart age was 80.81±9.11.
With regard to the Heart age, we observe an improvement of 6.76 and 7.33 years when comparing heart age pre-operatively, at 3 months and at 12 months follow-up. Both showing statistical significance (p=0.0001)
CONCLUSIONS: Our results suggest that laparoscopic bariatric procedures have a positive impact on patients with uncontrolled/resistant hypertension. This results also translates into significant cardiovascular disease risk reduction. Furthermore, the Cardiovascular disease risk reduction also demonstrates a most dramatical improvement in patients with resistant hypertension.
