Summary
Bradycardia, or a slow heart rate, can uncommonly cause angina pectoris, a type of chest pain. This study highlights three cases where slow heart rate led to angina, emphasizing its importance in diagnosis.
Area of Science:
- Cardiology
- Internal Medicine
Background:
- Angina pectoris is typically associated with coronary artery disease and increased heart rate.
- Coronary demand significantly influences myocardial oxygen supply-demand balance.
Observation:
- Bradycardia, a condition of abnormally slow heart rate, is an infrequent cause of angina.
- Three distinct cases of angina pectoris were observed in patients experiencing bradycardia.
Findings:
- The study identifies bradycardia as a potential, albeit rare, precipitant of angina pectoris.
- These findings underscore the necessity of considering bradycardia in angina evaluations.
Implications:
- Clinicians should consider bradycardia in the differential diagnosis of angina, especially in unexplained cases.
- Recognizing bradycardia-induced angina can lead to timely and appropriate management strategies.
