Summary
This trial is investigating whether or not calcium channel blockers and beta blockers, two common types of blood pressure medication, are effective in treating heart failure with preserved ejection fraction.
Who is the study for?
This trial is for adults aged 18-90 with stable high blood pressure treatment, diagnosed heart failure, specific elevated heart pressures, and a history of hypertension. They must have a normal left ventricular ejection fraction (>50%). Excluded are those with certain blood pressure levels, severe lung disease or coronary artery disease, allergies to the drugs tested, kidney issues (eGFR <30), or conditions affecting study participation.
What is being tested?
The trial investigates how two common blood pressure medications—Amlodipine Besylate (a calcium channel blocker) and Metoprolol Succinate (a beta-blocker)—impact heart function in patients with HFpEF. It aims to understand which medication better targets the physiological abnormalities associated with this type of heart failure.
What are the potential side effects?
Potential side effects include dizziness due to low blood pressure from Amlodipine Besylate and fatigue or shortness of breath from Metoprolol Succinate. Both drugs may cause swelling in the limbs and irregular heartbeat; individual reactions can vary.
