A myocardial infarction
(MI), also referred to as a coronary heart attack, occurs when blood glide decreases or stops to part of the coronary heart, causing harm to the coronary heart muscle. The most common symptom is chest ache or discomfort which may tour into the shoulder, arm, back, neck or jaw.
A blockage of blood glide to the coronary heart muscle.
A coronary heart assault is a medical emergency. A coronary heart assault commonly takes place when a blood clot blocks blood float to the coronary heart. Without blood, tissue loses oxygen and dies.
Symptoms encompass tightness or pain inside the chest, neck, back or arms, in addition to fatigue, lightheadedness, bizarre heartbeat and anxiety. Women are more likely to have atypical signs and symptoms than men.
Treatment tiers from way of life modifications and cardiac rehabilitation
to medication, stents and bypass surgery.
Many heart assault sufferers are warned of problem with the aid of episodes of angina, which is chest ache that, like a heart attack, is provoked with the aid of ischemia. The distinction is especially one in every of degree: With angina, blood flow is restored, ache recedes within minutes, and the heart is not permanently damaged. With a coronary heart attack, blood waft is significantly reduced or fully blocked, ache lasts longer, and heart muscle dies without prompt treatment.
About 25% of all heart assaults arise without any previous caution signs. They are now and again related to a phenomenon referred to as "silent ischemia" -- sporadic interruptions of blood waft to the heart that, for unknown reasons, are ache-free, although they will damage the heart tissue. The condition may be detected with the aid of ECG (electrocardiogram) testing. People with diabetes
frequently have silent ischemia.
