What are the risks of running for patients with coronary heart disease?
Disease description:
My grandfather enjoys morning jogging, but recently he has experienced palpitations and discomfort while running. He was diagnosed with coronary heart disease at the hospital. What are the risks of running for individuals with coronary heart disease?
Doctor's answer (1)
Dr. Tian Hongbo
There are certain risks for patients with coronary heart disease (CHD) when running, primarily because exercise increases the workload on the heart. Engaging in high-intensity or prolonged running without medical guidance may lead to the following issues:
1. Increased myocardial oxygen consumption: Vigorous exercise such as running can accelerate heart rate and elevate blood pressure, thereby increasing myocardial oxygen demand. This may result in an imbalance between oxygen supply and demand, potentially leading to myocardial ischemia and triggering angina attacks.
2. Risk of heart failure: Running can exacerbate the workload on the heart in patients with CHD, possibly leading to heart failure, which manifests as shortness of breath, edema, and, in severe cases, can be life-threatening.
3. Arrhythmias: High-intensity exercise may trigger arrhythmias, particularly in individuals with existing heart conditions, which could lead to serious consequences.
4. Myocardial ischemia: During running, the heart's demand for oxygen increases. For patients with CHD and narrowed coronary arteries, sufficient blood and oxygen may not be supplied to the myocardium, potentially causing angina.
