Exercise is vital for heart health, but a recent rise in “Gym Heart Attacks” highlights the risks of sudden, intense workouts. These episodes occur when strenuous exercise sharply spikes blood pressure, reducing blood flow to the heart and triggering cardiac arrest—especially in people with undiagnosed heart conditions. Factors like excessive strain, dehydration, electrolyte imbalance, smoking and drug use further increase the danger. Doctors stress that gym heart attacks are rare, and exercise remains beneficial when done safely. A pre-exercise health check-up, gradual progression, proper hydration, and awareness of red-flag symptoms can help prevent life-threatening complications and keep workouts safe.
Exercise has been a recognized pillar of heart health for a long time. India is a country with a staggering number of heart patients and incorporating exercise is one of the main lifestyle changes cardiologists recommend to them. However, in recent years a new, alarming trend has emerged – young adults, who appear physically fit, are suffering heart attacks in the gym, during a workout. This phenomenon has been termed a “Gym Heart Attack”. Celebrities and well-known fitness enthusiasts like actor Siddharth Surryavanshi, comedian Raju Shrivastav, actor Puneeth Rajkumar and Salman Khan’s body double Sagar Pandey have all suffered fatal heart episodes.
A “Gym Heart Attack” is a sudden heart episode caused by a reduction in blood flow to the heart muscles during strenuous exercise. Intense, strenuous workouts cause a sudden sharp spike in blood pressure. This is dangerous and can trigger a sudden cardiac arrest[5]. Without immediate medical support, the patient could die. Exercise is beneficial for heart health, but only in moderation. Sudden, explosive exercise, without proper precaution, can lead to undesirable consequences. Patients may collapse with chest pain, vomiting, shortness of breath, and heart palpitations if they are having a heart episode during their workout[6]. This is an emergency situation, and it is important to act quickly and get the patient to a hospital. A rapid response is crucial to saving the patient’s life.
Gym heart attacks appear unexpectedly and without warning. However, there are underlying patterns that connect patients who experience gym heart attacks:
Undiagnosed Heart Disease – Many patients who have suffered a heart attack at the gym have had an underlying heart condition that hasn’t been diagnosed. This includes conditions like hypertrophic cardiomyopathy, coronary heart disease[8] and congenital heart abnormalities. These conditions come to the fore when the heart is under extreme stress during a workout, and cause severe complications. It isn’t exactly the exercise that causes the heart episode, but it aggravates the underlying condition and triggers complications.
Excessive Strain during workouts – Exercise is intended to push you. However, it is important to set safe limits. The intensity of your exercise should be ramped up over time. A person with a sedentary lifestyle cannot suddenly run a marathon – It puts an unbearable amount of stress on the heart. During exercise, there is an increased demand for oxygen. The untrained heart cannot cope with the increased demand and becomes overwhelmed. At this time of crisis, any blockages or weak spots that have remained undiscovered can suddenly rupture, causing dangerous complications.
Smoking or Substance Abuse – Smoking and recreational drug use increases your risk of heart attacks. They weaken the heart and cause blood vessels to harden. As a result, the cardiovascular system becomes incapable of handling stress and increases in blood pressure. With sudden, explosive bursts of exercise, the blood pressure shoots up, increasing smokers’ risk of having a heart attack.
Dehydration and Electrolyte Imbalances – During strenuous workouts, essential electrolytes like sodium and potassium are lost through sweat. A lot of water is lost too. These minerals are necessary to maintain a normal heart rhythm[9]. Without these minerals, the heart’s electrical signals are not transmitted correctly. These disrupted electrical signals can increase the risk of heart arrhythmias[10] and cardiac arrest.
As doctors, we agree that it is healthy for everyone to work out and go to the gym, despite the new phenomenon of “Gym Heart Attacks”. Although this phenomenon appears to be increasing in frequency, it is still very rare. Patients need not avoid going to the gym or exercising out of fear of having a heart attack. It is important to understand the risk factors that could lead to a heart attack in the gym, and exercise cautiously. If you are new to exercising, it is a good idea to get a master health check-up and consult your family doctor[12] before you start going to the gym. A basic heart check-up, including blood pressure tests, ECG, cholesterol and blood sugar tests are recommended. These results can help your doctor identify any undiagnosed heart conditions you may have and treat you accordingly. If you have any family history of heart disease (which most Indians do), do not skip your health check-up before joining the gym.
It is also recommended to work out with a qualified trainer, who can tailor an exercise regimen with an intensity that will challenge you without wiping you out. The focus should be on moderate-intensity exercises initially, so that you can ramp up to challenge yourself as you get stronger. Avoid ego lifting and focus on proper form and technique. It is also important to educate yourself on the heart episode red flags – Chest pain, dizziness, breathlessness, vomiting, heart palpitations and black-outs. If you experience any of these symptoms during your workout, stop immediately and get medical help. Do not take these symptoms lightly; it may end up saving your life. Always remember – Safety First!
