Key Information About Myocardial Infarction
Commonly called heart attack, myocardial infarction occurs when blood flow to the heart muscle is abruptly cut off, causing tissue damage.
"Myo" means muscle, "cardial" refers to the heart, and "infarction" means death of tissue due to lack of blood supply.
Three types of myocardial infarction are:
- ST segment elevation myocardial infarction (STEMI)
- Non-ST segment elevation myocardial infarction (NSTEMI)
- Coronary spasm, or unstable angina
Myocardial infarction occurs when one of the heart's coronary arteries is blocked suddenly or has extremely slow blood flow, resulting in tissue damage.
Many factors, including bad cholesterol (low-density lipoprotein), saturated fats (found mostly in meat and dairy products) and trans fat (found in many processed foods), lead to a blockage in the coronary arteries.
Acute coronary syndrome associated with typical CAD is, by far, the most common cause of myocardial infarction.
Mild depression was a long-term independent predictor of death in patients after acute myocardial infarction (AMI), per cohort study data published in Heart, Lung and Circulation.— Cardiology Advisor
Sweating, nausea, vomit, dizziness, extreme weakness, shortness of breath, rapid heartbeats, irregular heartbeats, discomfort, pressure, heaviness, or pain in the chest, arm, or below the breastbone, discomfort radiating to the back, jaw, throat, or arm, fullness, indigestion and choking feeling are some known symptoms of myocardial infarction.
Symptoms generally last for around half an hour or more. Diabetics may have a heart attack without symptoms.
Myocardial infarction can be fatal, but treatment has improved dramatically over the years.
It depends on severity and ranges from lifestyle changes and cardiac rehabilitation to medication, stents and bypass surgery.
As a general rule, initial therapy for acute MI is directed toward restoration of perfusion as soon as possible to salvage as much of the jeopardized myocardium as possible.
This is usually accomplished through medical or mechanical means, like PCI, or CABG surgery.
Medications given right after the start of a heart attack may include aspirin, thrombolytic therapy, heparin and other antiplatelet drugs.
Maintain a healthy weight. Adhere to a heart-healthy diet. Do not smoke. Exercise regularly. Manage stress.
Control conditions that can result in heart attack, such as high blood pressure, high cholesterol and diabetes.
Blueberries Are Good for the Heart
Tomatoes are rich in lycopene and have been associated with a lower risk of heart disease and stroke, as well as an increase in ‘good’ HDL cholesterol.— Rachael Link, dietician.
