Summary
Beta-blockers generally do not harm peripheral circulation in patients without peripheral arterial disease. Caution is advised for severe peripheral arterial disease, but some benefit may occur in less severe cases.
Area of Science:
- Pharmacology
- Cardiovascular Medicine
- Vascular Biology
Background:
- Beta-blockers are widely used for cardiovascular conditions.
- Their impact on peripheral circulation requires clarification, especially in diverse patient groups.
Purpose of the Study:
- To review the vascular effects of beta-blockers.
- To assess these effects in patients with normal circulation, hypertension, and peripheral arterial disease.
Main Methods:
- Review of existing uncontrolled and small-scale studies.
- Analysis of data concerning beta-blocker use and peripheral circulation outcomes.
Main Results:
- No significant adverse effects on peripheral circulation in patients without peripheral arterial disease.
- Potential for cold extremities with non-selective beta-blockers, especially in hypertension.
- Beta-blockers generally safe in peripheral arterial disease, with caution in severe cases; potential benefit in less severe occlusive disease.
Conclusions:
- Beta-blockers can be used cautiously in peripheral arterial disease.
- Switching to beta-1 selective agents or those with intrinsic sympathomimetic activity (ISA) may alleviate cold extremities.
- Long-term antihypertensive treatment with beta-blockers may improve vascular architecture.
