High-Intensity Exercise & Heart Attack Risk: What You Need to Know

Spread the love



A heart attack while working out can be a frightening and sometimes fatal experience. Physical activity increases cardiac strain, which can result in a heart attack in those with underlying cardiac issues. Intense chest pain or discomfort, shortness of breath, nausea, dizziness, and even pain spreading to the arms, neck, jaw, or back are some of the symptoms that can develop during an exercise-related cardiac attack. It’s critical to identify these warning signals as soon as possible, particularly while engaging in physical activity, as ignoring them or putting up with the discomfort might make things worse.

Heart Attack


If you think you could be having a heart attack while exercising, you need to act quickly. Put an immediate stop to your physical activity and call emergency services to get emergency medical assistance. Chewing and swallowing an aspirin, if it’s not allergic, is essential if you or someone else is exhibiting heart attack-like symptoms since it can assist lower blood clotting. It’s important to remain composed and not exert yourself while you wait for medical help to come. Early medical care reduces the risk of possible cardiac muscle injury and greatly increases the odds of survival.

Reasons for Heart Attacks When Exercising 

CAD, or coronary artery disease: When plaque (atherosclerosis) accumulates in the blood channels that supply the heart muscle with oxygen-rich blood, the condition known as CAD results. The heart needs more oxygen and blood when exercising, and if the arteries are already restricted, a clot may develop and cause a heart attack.

Rupture of plaque: Occasionally, the accumulation of plaque in the arteries may burst or rupture, causing a blood clot to develop. A heart attack may result from this clot obstructing an artery supplying blood to a portion of the heart, particularly during physical activity when the body’s need for blood flow increases.

Stress on the heart: Excessive strain on the heart can result from abrupt or intense physical activity, particularly in those who do not engage in regular physical activity. The heart may require more oxygen and blood flow as a result of this stress. Underlying medical issues can hamper the heart’s blood supply, potentially leading to a heart attack.

High blood pressure (hypertension): If left unchecked, hypertension can cause long-term damage to the arteries and increase their susceptibility to plaque accumulation. Elevated blood pressure and constricted arteries during exercise can raise the risk of a heart attack.

Arrhythmias: During physical activity, abnormal cardiac rhythms such ventricular fibrillation or tachycardia might happen. These erratic heartbeats may cause the heart to become less efficient in pumping blood, which may result in an abrupt cardiac event such as a heart attack.

Undiagnosed cardiac diseases: Some people may be suffering from heart disorders that go undiagnosed, such congenital heart defects or other structural abnormalities. These illnesses might raise an individual’s chance of having a heart attack when exercising.

Lifestyle issues: Heart attacks during exercise can be exacerbated by a number of variables, including smoking, a sedentary lifestyle, obesity, poor food, excessive alcohol use, and stress.

Heart Attack


Who Runs the Risk of Having a Heart Attack When Working Out?

Even while exercise is usually good for heart health, some people may be more susceptible to having a heart attack when they exercise. A increased risk can be attributed to the following factors:

Underlying Heart Conditions: People who already have a history of heart attacks, heart failure, arrhythmias, coronary artery disease, or congenital heart abnormalities may be more vulnerable.

Family History: An individual’s risk may be elevated if their family has a history of heart disease or abrupt cardiac events.

Age: The risk of heart disease often rises with age. The risk of having a heart attack while exercising may be increased in older people.

Sedentary Lifestyle: People who have never exercised regularly are more likely to develop heart disease, and those who have never exercised vigorously before may experience cardiac strain.

Smoking: One of the main risk factors for heart disease is smoking. Smoking may increase the risk of a heart attack because of the stress it puts on the heart and blood vessels.

Heart Attack


High Blood Pressure: If left unchecked, hypertension can raise the chance of having a heart attack when exercising.

High Cholesterol Levels: A higher risk of heart attack can be attributed to the development of plaques in the arteries caused by elevated levels of low-density lipoprotein (LDL), also known as “bad” cholesterol.

Diabetes: People with diabetes may be more susceptible to a heart attack when exercising and have an increased risk of heart disease.

Being overweight or obese: Being overweight puts undue strain on the heart and raises the chance of developing heart disease, particularly when paired with other risk factors.


Preventive Actions

Although it’s terrifying to think that you may have a heart attack while exercising, there are steps you can do to reduce the risk. Here are a few precautions to take:

Gradual Progression: Increase the duration, frequency, and intensity of your workouts progressively after starting off gently. Over time, let your body adjust to the physical demands of exercise.

Warm-up and Cool-down: To prepare your muscles and cardiovascular system, always warm up before exercising. In a similar vein, allow your body to progressively return to resting condition by cooling down after exercise.

Recognise your limits: Pay attention to how your body feels and avoid overdoing it. Overexerting yourself beyond your level of fitness can put stress on your heart and raise your chance of having a heart attack.

Remain Hydrated: Make sure you have enough fluids before, during, and after exercise. Your heart may strain from dehydration, which can also impair your general function.

Heart Attack


Healthy Lifestyle: Eat a balanced diet full of fruits, vegetables, whole grains, lean protein, and healthy fats to lead a heart-healthy lifestyle. Steer clear of high-fat meals, sugary drinks, and processed foods in excess.

Keep Your Weight Within a Healthy Range: Being overweight puts undue strain on your heart and raises your chance of developing heart-related problems.

Frequent Exercise: Exercise on a frequent basis to strengthen your heart muscle and enhance your cardiovascular health in general. Try to get in at least 150 minutes a week of moderate-to-intense activity, or as advised by your physician.

Recognise the Warning Signs: If you have any of the following symptoms, it might be a heart attack: nausea, lightheadedness, shortness of breath, arm, neck, jaw, or back pain. Should you encounter any of these signs, cease working out right once and get medical attention.


When to Get Medical Help 

It’s critical to respond right away if you exercise and suffer symptoms that could be signs of a heart attack. The following symptoms indicate when you should seek medical attention:

The most typical symptom is pain or discomfort in the chest. It may feel as though there is fullness, squeezing, pressure, or discomfort in the middle of the chest; it may also come and go for a few minutes.

Pain or Discomfort in Other Areas: Back, neck, jaw, stomach, or one or both limbs.

Breathlessness: This can happen with or without pain in the chest.

Additional Symptoms: Feeling sick to the stomach, dizziness, or a cold sweat might also be indicators.

If any of the following symptoms appear when you exercise:

Put an end to the exercise right away, then take a nap.

Observe Directions: If your doctor has recommended nitroglycerin for your chest discomfort, take it as instructed.


It’s critical to not disregard these symptoms or put off getting medical attention. During a heart attack, every minute matters, and receiving treatment quickly can maximise survival rates and reduce cardiac damage.

when exercise is usually good for heart health, it’s important to be aware of your limitations, raise the intensity gradually, and pay attention to any warning indications your body may give you when engaging in physical activity.
