Predictors of complete remission of hypertension in patients over 65 years of age after bariatric surgery - a multicenter study.

INTRODUCTION

In the era of an aging society and a growing number of obese people, an increasing number of older patients are consulting bariatric surgeons. The incidence of hypertension (HT) also rises with age and body weight, making the treatment of the elderly a significant challenge.

AIM

To identify predictors of HT remission after bariatric surgery in patients over 65 years of age.

MATERIAL AND METHODS

A retrospective study analyzed patients over 65 years old with HT who underwent laparoscopic bariatric procedures in Poland between 2008 and 2022. The data came from 11 bariatric centers. Patients were categorized into two groups: responders (R) and non-responders (NR). A multivariate logistic regression analysis was conducted to identify significant independent risk factors.

RESULTS

The study analyzed 244 patients, with complete HT remission observed in 55 (22.5%) patients. Almost 90% of patients showed improvement in HT. The mean follow-up time was 47.4 months. Factors contributing to HT remission included HT duration of less than 5 years, the use of single medication, and a significant correlation with %EWL.

CONCLUSIONS

Bariatric surgery in patients aged over 65 has a positive effect on HT remission. The chance of HT remission increases with fewer medications, shorter HT duration, and greater weight loss after surgery.
