Myocardial Infarction is the technical name for a heart attack; it is the interruption of blood supply to part of the heart, causing few heart muscle cells to die. It is most commonly due to occlusion of a coronary artery following the rupture of a vulnerable atherosclerotic plaque, which is an unstable collection of lipids and white blood cells in the wall of an artery.
The term “Myocardial Infarction” focuses on the myocardium (the heart muscle) and the changes that occur in it due to the sudden deprivation of circulating blood. The main change is necrosis (death) of myocardial tissue. The word “infarction” comes from the Latin “infarcire” meaning “to plug up or cram.” It refers to the clogging of the artery.
Signs and Symptoms of Myocardial Infarction:
The most common symptom of a heart attack in both men and women is some type of pain, pressure or discomfort in the chest. But it’s not always severe or even the most prominent symptom, particularly in women. Women are more likely than men to have signs and symptoms unrelated to chest pain, such as:
- Feeling of doom
- Nausea, vomiting
- Irregular heartbeat
- Shortness of breath
- Dizziness, weakness
- Pain that spreads to your back, left arm, jaw, neck
- Squeezing pain, heaviness, tightness, pressure in center of chest
Symptoms Experienced by Women may Include:
- Clammy skin
- Unusual fatigue
- Heartburn or pain in the abdomen
Causes of Myocardial Infarction:
The most common cause of blocked arteries is atherosclerosis. No one knows the exact cause of atherosclerosis. But most researchers believe it begins with an injury to the innermost layer of the artery, known as the endothelium. The following factors are thought to contribute to the damage:
- High blood pressure
- Elevated LDL (“bad”) cholesterol
Risk Factors of Myocardial Infarction:
- Age, Stress, Smoking, Diabetes
- Gender (men are at higher risk than women)
- High-fat diet, Lack of exercise, High blood pressure
- High LDL “bad” cholesterol and triglycerides (fats in the blood)
Diagnosis of Myocardial Infarction:
- Stress test
- Blood tests
- Chest x-ray
- Electrocardiogram (ECG)
- Coronary Catheterization or Angiogram
Treatment of Myocardial Infarction:
The goal when treating a heart attack is to restore blood flow to the affected area of the heart immediately, to preserve as much heart muscle and heart function as possible. If your doctor has prescribed nitroglycerin, take it while you are waiting for emergency medical personnel to arrive. Once at the hospital, your doctor may use drug therapy, angioplasty, and surgery.
Once you have been treated for a heart attack, making changes in your lifestyle, and taking medications as prescribed are very important for avoiding recurrent heart attacks and even death. Although certain herbal remedies as well as relaxation techniques may also be used, they should never be used alone to treat a heart attack. A heart attack always requires emergency medical attention.
