A myocardial infarction occurs when blood flow to a part of the heart is blocked, causing damage to the heart muscle. This blockage is usually due to a buildup of fatty deposits, known as plaque, in the coronary arteries. When the blood flow is cut off, the affected heart tissue can become damaged or die, leading to serious health complications.
Understanding myocardial infarction is crucial because it is a leading cause of death worldwide. Recognizing the symptoms early can save lives, as timely medical intervention can restore blood flow and limit heart damage. Common symptoms include chest pain, shortness of breath, and discomfort in the arms, back, neck, or jaw.
The heart's primary function is to pump blood throughout the body, supplying oxygen and nutrients to tissues while removing waste products. When a myocardial infarction occurs, the heart's ability to function properly is compromised. This can lead to heart failure, arrhythmias, and other serious cardiovascular issues.
It is important to be aware of risk factors for myocardial infarction, such as high blood pressure, smoking, and diabetes, to help reduce the chances of having a heart attack in the future.
