Can Fitness Mask Heart Disease Risk?

The death of shooting legend Jaspal Rana at age 49 has highlighted a growing medical concern: the “fitness paradox,” where high physical performance masks underlying cardiovascular risks like arterial blockages or genetic predispositions. Experts suggest future health trends will shift from general fitness tracking toward advanced genetic screening and proactive vascular monitoring to prevent sudden cardiac events in active individuals.

Why does high physical fitness not guarantee heart health?

Medical professionals are increasingly distinguishing between physical stamina and actual cardiovascular condition. While an athlete may possess the endurance to compete at an elite level, their internal vascular system may still be failing.

Dr. Ramneek Mittal, a Consultant Cardiologist at Narayana Health City in Bengaluru, tells South First that physical fitness and cardiovascular health are not synonymous. Fitness measures how well a person performs tasks like running or lifting, whereas cardiovascular health refers to the state of arteries, cholesterol, and blood pressure.

One dangerous physiological adaptation is collateral circulation. Dr. Mittal notes that regular exercisers can develop alternative blood pathways around narrowing arteries. This allows the body to sustain high-intensity training even as disease progresses, often making the first visible sign a sudden heart attack.

“A person can look healthy, maintain excellent fitness levels, and still have significant blockages in the heart arteries,” says Dr. PRLN Prasad, Consultant Interventional Cardiologist at Gleneagles BGS Hospitals.

How will genetic markers like Lipoprotein(a) shape future screening?

Future preventative medicine is moving toward identifying risks that exercise cannot touch. A primary target is Lipoprotein(a), a genetic variant of LDL cholesterol.

Unlike standard cholesterol, Lipoprotein(a) levels are largely unaffected by diet or physical activity. Dr. Mittal explains that many people maintaining healthy weights and active lifestyles carry elevated levels without knowing it. Because this risk is hard-coded into DNA, cardiologists expect a shift where genetic testing becomes a standard part of athletic physicals, rather than an afterthought.

Current medical consensus suggests that relying solely on body mass index (BMI) or aerobic capacity is insufficient. Future trends will likely prioritize “biochemical profiles” that include family history, Lipoprotein(a) levels, and chronic stress indicators.

Can wearable technology prevent the “dismissed symptom” trap?

A recurring theme in sudden cardiac deaths among athletes is the tendency to rationalize warning signs. In the case of Jaspal Rana, reported symptoms were attributed to indigestion or acidity before a fatal cardiac rupture occurred.

Dr. Prasad notes that active individuals often interpret chest tightness as muscle strain or breathlessness as overtraining. To combat this, the next generation of wearable technology is expected to move beyond step-counting and toward clinical-grade symptom detection.

Future devices may integrate AI to recognize patterns of angina—discomfort that appears during exertion and improves with rest. By flagging these specific patterns, wearables could prompt users to seek medical attention before a blockage leads to a complete rupture.

What happens when treatment is delayed?

The concept of “time is muscle” remains the most critical factor in cardiac survival. Dr. MSS Mukharjee, Senior Interventional Cardiologist at Pulse Heart Super Speciality Hospital, emphasizes that once an artery is blocked, heart muscle begins to die immediately.

While modern medicine can often reopen a blocked artery using stents, the damage done during the delay is often permanent. Dr. Mukharjee explains that if blood supply is lost for several days, even successful surgery cannot revive the dead muscle. This can result in long-term complications such as heart failure, reduced exercise capacity, and kidney issues.
