Overview

Prehypertension is recognized clinically as a precursor to hypertension, an independent predictor of cardiovascular disease (CVD) risk. Vascular and sympathetic nervous system dysfunction are non-traditional risk factors contributing to increased CVD risk that are mediated, in part, by systemic inflammation and oxidative stress. Targeting vascular and sympathetic nervous system function represents a therapeutic strategy for mitigating CVD risk in prehypertension.

Sodium-glucose cotransporter-2 (SGLT2) inhibitors (e.g., empagliflozin) have emerged as a transformative therapeutic class with robust anti-inflammatory and antioxidant properties. The efficacy of SGLT2 inhibitors to improve vascular and sympathetic nervous system function through reductions in pro-inflammatory and improved redox balance have yet to be investigated in prehypertension.

In this randomized, double-blind, placebo-controlled clinical trial, the investigators seek to utilize integrative methods for evaluating vascular and sympathetic nervous system function following 2-week treatment with empagliflozin. Understanding the mechanisms underpinning increased CVD risk in prehypertension will inform us about specific pharmacological prevention strategies in this ever-growing clinical population.
