    Summary

    The dipyridamole test, used for coronary artery disease, can cause significant cardiac and extracardiac side effects. Continuous ECG monitoring is crucial due to potential serious adverse events.

    Area of Science:

    • Cardiology
    • Clinical Pharmacology

    Background:

    • The dipyridamole test is a common diagnostic tool for patients with suspected coronary artery disease.
    • Evaluating the safety profile of pharmacological stress agents is essential for patient care.

    Observation:

    • This study investigated cardiac and extracardiac side effects in 203 patients undergoing the dipyridamole test.
    • Adverse events included significant heart rate increases, dyspnea (40.5%), and rhythm disturbances (23.6%).
    • Extracardiac side effects, such as headache and nausea, affected 58.1% of patients.

    Findings:

    • High-dose dipyridamole administration can lead to serious adverse events, including life-threatening conditions like status anginosus.
    • A notable case presented with dyspnea, ST-segment elevation, and cardiac arrhythmia post-injection.
    • The dipyridamole test is not without risk and requires careful patient monitoring.

    Implications:

    • The findings underscore the importance of continuous electrocardiogram (ECG) monitoring and safety precautions during dipyridamole testing.
    • Clinicians should be aware of the potential for severe adverse reactions.
    • Risk-benefit assessment is crucial when considering this diagnostic procedure for coronary artery disease.
