Heart diseases have become more common than ever, and there are several contributing factors to this trend. Similarly, an alarming rise in serious cardiac events while exercising, particularly among gym-goers, has also been observed over the past few years. This can be attributed to a combination of lifestyle factors, health conditions, and, in some cases, the intensity of workouts. On World Heart Day 2025, let's learn about the causes, symptoms, and preventive measures for cardiovascular events during exercise straight from our expert.
What causes sudden cardiac ailments during exercise in young population?
"Physical fitness is widely considered an essential part of a healthy lifestyle. Many young adults and fitness enthusiasts regularly challenge themselves in gyms, studios, and sports fields to build endurance and strength. Yet, beneath this appearance of health, hidden cardiac conditions can exist silently - sometimes showing up only during intense physical activity. Even those who appear fit and active may be at risk of sudden cardiac events," explains Dr. Sridhara N, Director - Cardiology, Fortis Hospital, Rajajinagar, Bengaluru.
"Hypertrophic cardiomyopathy (the most common cause), dilated cardiomyopathy, arrhythmogenic right ventricular dysplasia (ARVD), congenital coronary artery anomalies, long QT syndrome, Brugada syndrome, connective tissue disorders and undiagnosed congenital heart diseases," the expert explained the medical causes of sudden heart disease.
Other than a sedentary lifestyle, obesity, increased levels of stress and underlying health issues like hypertension, diabetes, or dyslipidemia, the intensity of exercise also plays a role. As more people adopt intense workout regimens, there can be an increased risk of cardiac events, especially if individuals push themselves beyond their limits without adequate preparation or supervision.
