Effect of Nitrate Supplementation on Blood Pressure and Systemic Microvascular Function of Resistant Hypertensive Patients

Arterial hypertension (AH) has been identified as an important public health problem and considered a new epidemic with high mortality and morbidity. High blood pressure (BP) levels increase the chances of coronary artery disease (CAD), heart failure (HF), stroke, chronic renal failure (CRF) and death.

However, studies are needed to evaluate its benefits in patients with AH.
