It was found that the risk of sudden cardiac arrest did not increase even if the intensity of exercise was five times or more than the recommended amount of exercise. Ewha Womans University Mokdong Hospital Cardiology Professor Jin Mu-nyeon (pictured), who uncovered this, won the ‘2022 Korean Arrhythmia Society Academic Award’ at the regular meeting of the Korean Arrhythmia Society held at the Westin Chosun Hotel in Seoul on the 2nd.
Professor Jin was recognized for his research achievements on the association between physical activity in the general public and the risk of sudden cardiac arrest. The study found that participants who performed physical activity at two-thirds of the minimum amount of exercise recommended by the US and World Health Organization guidelines had a lower risk of sudden cardiac arrest compared to participants who were physically inactive. In addition, the risk of sudden cardiac arrest did not increase even with a high exercise amount of more than 5 times the minimum recommended exercise amount.
Sudden, sudden death is most often due to heart problems. In particular, 80-90% of sudden cardiac deaths are manifested with the appearance of fatal arrhythmias. Sudden cardiac death appears unexpectedly and suddenly, leading to death, so prevention is more important than anything else. In particular, thorough management is necessary for patients who already have heart disease such as atrial fibrillation, coronary artery disease, or heart failure. Depending on the patient’s risk, drug treatment or an implantable defibrillator called ICD may be required, but all patients need proper exercise management.
Professor Jin said, “Depending on the patient’s condition, too much exercise can cause sudden cardiac arrest, which can be a major factor in hesitating to exercise. It is necessary to suggest appropriate physical activity to patients with heart disease.” said.
