A heart attack occurs when a blood clot completely blocks a coronary artery that supplies blood to the heart muscle and the heart muscle dies. The blood clot that causes the heart attack usually forms at the site of the rupture of a cholesterol atherosclerotic plaque on the inside wall of a coronary artery. Risk factors for a heart attack include high cholesterol levels, increased blood pressure, tobacco use, diabetes and a family history of heart attacks at an early age.
Excessive sweating can be an early warning sign of a heart attack, according to the British Heart Foundation.
While it is normal to feel sweat on a hot day or after intense exercise, sweating for no obvious reason can be a heart attack. You are at risk of suffering a myocardial infarction if excessive sweating is accompanied by the characteristic chest pain.
The British Heart Foundation said: “Heart attack symptoms vary from person to person.
"It is possible to have a heart attack without experiencing chest pain & # 39; classic & # 39;"
Sweating when a person does not have a fever and is not exercising or in a hot environment, especially if accompanied by other symptoms, such as light-headedness, shortness of breath, nausea or chest pain, can be a symptom of a heart attack . not be ignored.
Most people with heart attacks experience some type of chest pain or discomfort. However, it is important to understand that chest pains do not occur in all heart attacks. Chest pain is a common sign of a heart attack. People described this feeling as if they were feeling an elephant standing on their chest.
The pain can also be felt in the shoulder, legs or arms.
The difference between heart disease and heart attacks
Heart failure and heart attack are both forms of heart disease. Most heart attacks occur suddenly when one of the arteries leading to the heart becomes blocked and interrupts blood flow. Without oxygen, the heart muscles begin to die. Heart failure, on the other hand, usually develops gradually.
The NHS advises how to prevent a heart attack and said: “Excess weight forces the heart to try harder to pump blood around the body, which can increase your blood pressure. Use the BMI healthy weight calculator to find out if you are a healthy weight for your height.
“If you need to lose weight, remember that losing just a few pounds will make a positive difference in your blood pressure and health.
“Being active and exercising regularly will reduce blood pressure, keeping your heart and blood vessels in good condition.
"Regular exercise can also help you lose weight, which will help lower your blood pressure and reduce your risk of heart attacks."
