Regular exercise is crucial for maintaining cardiovascular health, but intense workouts can sometimes pose risks—especially for individuals with underlying heart conditions. Heart attacks occurring in the gym, although uncommon, are a serious concern. Dr. Tanmai Yermal, a leading Consultant Interventional Cardiologist in Kharadi, Pune, emphasizes the importance of understanding these risks, recognizing warning signs, and taking preventive measures to ensure safe workouts.
Why Do Heart Attacks Occur in the Gym?
A heart attack, or myocardial infarction, occurs when the blood supply to the heart is suddenly blocked, often due to a clot in the coronary arteries. While exercise is generally beneficial for heart health, certain factors can trigger cardiac events during workouts:
1. Undiagnosed Heart Disease
Many people may have silent coronary artery disease (CAD) without knowing it. When they engage in strenuous exercises like weightlifting or high-intensity interval training (HIIT), the sudden demand for oxygen-rich blood may exceed the heart’s ability to supply it, leading to a heart attack.
2. Overexertion
Pushing beyond one’s fitness level—especially without proper warm-up or gradual progression—can put excessive strain on the heart. Lifting heavy weights or performing prolonged intense cardio can elevate blood pressure and heart rate, increasing the risk of cardiac events.
3. Dehydration and Electrolyte Imbalance
Excessive sweating can lead to dehydration and imbalanced electrolyte levels, affecting heart rhythm. A lack of proper hydration can cause irregular heartbeats (arrhythmias), increasing the chances of sudden cardiac arrest.
4. Pre-existing Conditions
People with conditions like hypertension, diabetes, high cholesterol, and obesity have a higher risk of heart attacks. Those who smoke, consume excessive alcohol, or have a family history of heart disease should be particularly cautious while exercising.
5. Use of Performance-Enhancing Substances
Some gym-goers take pre-workout supplements, anabolic steroids, or energy drinks that contain high doses of caffeine and stimulants. These can elevate blood pressure, cause palpitations, and trigger a cardiac event.
Warning Signs of a Heart Attack During Exercise
Dr. Yermal advises paying close attention to these early symptoms of a heart attack while working out:
- Chest pain or discomfort – A feeling of pressure, squeezing, or pain in the center of the chest that lasts more than a few minutes.
- Shortness of breath – Difficulty breathing, even at moderate exercise intensity.
- Dizziness or lightheadedness – Feeling faint or weak during or after exercise.
- Pain in arms, jaw, or back – Discomfort that radiates beyond the chest.
- Cold sweat and nausea – Unexplained sweating, vomiting, or flu-like symptoms.
Tip: If you or someone nearby experiences these symptoms, stop exercising immediately and seek emergency medical help. A delay in treatment can be life-threatening.
How to Prevent Heart Attacks While Exercising
Dr. Tanmai Yermal recommends the following precautionary measures for safer workouts:
1. Get a Heart Health Check-Up
Individuals over 40, or those with risk factors like high blood pressure, diabetes, or family history of heart disease, should undergo a cardiac evaluation before starting a new fitness program. Tests such as ECG, stress test, and coronary angiography can help assess heart health.
2. Warm Up and Cool Down
A proper warm-up (5-10 minutes) prepares the heart for exertion, while a cool-down gradually lowers the heart rate, preventing sudden drops in blood pressure.
3. Avoid Overexertion
- Exercise within your capacity and gradually increase intensity.
- If you experience chest discomfort or severe breathlessness, slow down or stop.
- Incorporate moderate-intensity workouts (brisk walking, cycling, yoga) instead of extreme exercises.
4. Stay Hydrated
- Drink water before, during, and after workouts.
- Avoid excessive caffeine or energy drinks, as they can increase heart rate and blood pressure.
5. Monitor Your Heart Rate
- Wear a heart rate monitor or use gym equipment that tracks pulse rate. Aim for a safe target heart rate (THR) based on your age and fitness level.
6. Know Your Limits with Weight Training
- Avoid sudden, excessive weightlifting, which can cause a spike in blood pressure.
- Use proper breathing techniques—never hold your breath while lifting heavy weights.
- Gradually increase resistance rather than attempting one-rep max lifts.
7. Listen to Your Body
- Feeling unusually fatigued, dizzy, or nauseated? Take a break. Ignoring these signs could lead to serious complications.
8. Have a Gym Emergency Plan
- Ensure your gym has an AED (Automated External Defibrillator) and trained staff to handle cardiac emergencies.
- Know where emergency exits and first-aid stations are located.
Who Should Be Extra Cautious in the Gym?
- People with pre-existing heart conditions (coronary artery disease, high blood pressure, arrhythmias).
- Individuals above 50 years of age or those with a family history of heart disease.
- Diabetics and smokers, as they are at higher risk of arterial blockages.
- Those returning to the gym after a long break or post-COVID recovery should start with low-intensity exercises.
Expert Tip from Dr. Tanmai Yermal:
If you're starting a workout routine after a long gap or have any cardiovascular risk factors, consult a cardiologist before engaging in high-intensity exercises. Prevention is the key to safe and effective fitness!
The gym should be a place for strength, endurance, and health—not a risk for cardiac emergencies. By understanding your heart health, training smartly, and recognizing warning signs, you can enjoy a safe and effective workout routine.
