Summary
Asymptomatic individuals may experience transient ischemic electrocardiogram changes due to coronary artery vasospasm. Nifedipine therapy effectively resolved these episodes, preventing symptoms and cardiac events over four years.
Area of Science:
- Cardiology
- Clinical Medicine
Background:
- Electrocardiogram (ECG) monitoring can reveal transient ischemic changes.
- Coronary artery vasospasm is a potential cause of myocardial ischemia.
Observation:
- A 46-year-old asymptomatic male presented with ST elevations on basal ECG.
- Resting ECG monitoring revealed numerous asymptomatic transient ischemic episodes in inferior and anterolateral leads.
- Coronary arteriography showed no significant stenosis but indicated multivessel coronary artery spasm.
Findings:
- Coronary artery vasospasm was identified as the cause of the ischemic ECG changes.
- Nifedipine therapy led to the disappearance of ischemic ECG episodes.
- The patient remained asymptomatic with no coronary events during a 4-year follow-up.
Implications:
- Asymptomatic coronary artery vasospasm can manifest as transient ischemic ECG changes.
- Nifedipine is an effective treatment for managing coronary artery vasospasm.
- Early diagnosis and treatment of coronary vasospasm can prevent adverse cardiac events.
