Amlodipine significantly lowered systolic blood pressure in patients with heart failure with preserved ejection fraction (HFpEF). This study suggests dihydropyridine calcium channel blockers are a preferred hypertension treatment for HFpEF patients.
Area of Science:
- Cardiology
- Pharmacology
- Clinical Trials
Background:
- Hypertension affects 90% of patients with heart failure with preserved ejection fraction (HFpEF).
- Hypertension is a key modifiable risk factor for HFpEF development.
- Limited randomized controlled trial evidence exists for hypertension management in HFpEF.
Purpose of the Study:
- To compare the efficacy of amlodipine versus metoprolol succinate in managing hypertension in patients with HFpEF.
- To evaluate the impact of amlodipine and metoprolol on systolic blood pressure and other clinical outcomes in HFpEF.
Main Methods:
- A double-blind, randomized, crossover trial involving 50 adults with HFpEF and hypertension.
- Participants received amlodipine (5-10 mg) or metoprolol succinate (100-200 mg) for 4 weeks each.
- Primary outcome: difference in mean home systolic blood pressure during the final week of each treatment.
Main Results:
- Amlodipine resulted in a 4 mm Hg lower systolic blood pressure compared to metoprolol (P=0.017).
- Amlodipine improved peak oxygen uptake and physical activity levels.
- Amlodipine significantly reduced NT-proBNP levels (P<0.0001) with similar adverse event rates.
Conclusions:
- Dihydropyridine calcium channel blockers, like amlodipine, are a preferred alternative to beta-blockers for hypertension management in HFpEF.
- The findings support amlodipine's role in improving key clinical markers in HFpEF patients.
