Exercise-Induced Ischemia — When Exercise Exposes a Blood-Flow Problem
Exercise increases the heart’s demand for oxygen and blood flow. In a healthy coronary circulation, blood flow increases to meet that demand.
But when a coronary artery is significantly narrowed, blood supply may not increase enough during exercise → myocardial ischemia can occur.
Key point:
Ischemia doesn’t necessarily mean the heart has stopped receiving blood. It means oxygen supply is insufficient relative to the heart muscle’s demand.
⚠️ Possible symptoms include:
• Chest pressure or discomfort or Pain
• Shortness of breath
• Unusual fatigue
• Dizziness
• Pain/discomfort radiating to the arm, jaw, back or shoulder
• Sometimes no symptoms at all (silent ischemia)
Fitness professional takeaway:
Chest discomfort or unusual symptoms during exercise should never be “trained through.” Stop exercise and seek appropriate medical evaluation.
Train hard. But understand when the heart is asking you to stop. ❤️
