Doctor and marathon runner Yevgeny Suborov recalled how to protect the heart in case of ischemic heart disease
According to the Association of Cardiovascular Surgeons of Russia, coronary heart disease remains the leading cause of death in the population of developed countries. Regular physical activity will help patients with coronary artery disease not replenish the sad statistics and improve heart function.

People with coronary artery disease are advised to exercise at a moderate pace every day, such as walking for at least 30 minutes a day, household activities such as cleaning, gardening, and walking from home to work. Patients after a heart attack and heart failure need an individual physical rehabilitation program, which is important to adhere to throughout their lives.
On his Facebook page, anesthesiologist-resuscitator and marathon runner Yevgeny Suborov wrote that regular exercise has proven effective in reducing heart damage during ischemia, which manifests itself in insufficient blood supply, and reperfusion, when a large amount of aggressive substances. The benefits of exercise have been proven both in experimental rodent models and in scientific experiments on humans. However, the cellular and molecular mechanisms of heart-protecting effects are still unclear.
“During ischemia and reperfusion, mitochondria play a decisive role in cell death, and they are also actively involved in the opposite situation - in cell survival during extreme conditions of ischemia / reperfusion. While regular exercise can affect mitochondrial function, the implications for the sensitivity of the heart to ischemic attacks and subsequent reperfusion (as happens, say, with myocardial infarction) remain unclear,”Suborov writes.
The doctor refers to a study published in the journal Free Radical Biology and Medicine, which describes the effect of regular physical activity on the mitochondria of the heart and their potential key role in shaping the protection of the heart against damage during the development of ischemia and reperfusion.
Scientists have made several conclusions:
- Regular physical activity affects the energy metabolic process in the heart and the function of mitochondria;
- Exercise improves cardiac antioxidant capacity;
- Sports activities can limit the overload of mitochondria with calcium that usually develops during ischemia / reperfusion;
- Regular exercise can increase the heart's content of mitochondrial nitric oxide, the main substance that causes vasodilatation, during an ischemia / reperfusion episode.
- Exercise has a positive effect on the development of the mitochondrial network in the heart, which is very important during a stressful situation.
Thus, regular exercise is a very healthy habit that can not only reduce risk factors for cardiovascular disease, but also improve heart function and survival in people with coronary heart disease, the authors say.
