Improved physical performance as a therapeutic objective in patients with angina
British Journal of Clinical Pharmacology
|January 1, 1979
Summary
Beta-blocker therapy, including nadolol and propranolol, effectively treats angina by improving physical performance. This enhanced physical capacity correlates with reduced angina attacks and nitroglycerin needs in cardiac rehabilitation patients.
Area of Science:
- Cardiology
- Pharmacology
- Rehabilitation Medicine
Background:
- Anti-anginal therapy is crucial for cardiac patient rehabilitation.
- Measuring treatment efficacy often involves assessing physical performance and patient-reported outcomes.
Purpose of the Study:
- To evaluate physical performance as a key measure for anti-anginal therapy efficacy.
- To compare the effectiveness of nadolol and propranolol in managing angina.
Main Methods:
- Assessed physical performance through exercise tolerance, self-assessed work capacity, and physician-rated functional capacities.
- Monitored anginal attack frequency and nitroglycerin requirements.
- Administered nadolol once daily and propranolol four times daily.
Main Results:
- Improved physical performance was observed as a measure of anti-anginal therapy efficacy.
- Enhanced physical performance paralleled reductions in angina frequency and nitroglycerin use.
- Nadolol, administered once daily, demonstrated comparable efficacy to propranolol (four times daily) as an anti-anginal agent.
Conclusions:
- Physical performance is a valid and sensitive indicator for assessing anti-anginal treatment effectiveness in cardiac rehabilitation.
- Once-daily nadolol offers a convenient and effective alternative to multiple daily doses of propranolol for angina management.
