What is Heart Attack ?
Heart attack (or Myocardial infarction)
results from the interruption of blood supply to a part of the
heart, causing heart cells to die. This is most commonly due to
occlusion (blockage) of a coronary artery following the rupture
of a vulnerable atherosclerotic plaque, which is an unstable
collection of lipids (cholesterol and fatty acids) and white
blood cells (especially macrophages) in the wall of an artery.
The resulting ischemia (restriction in blood supply) and ensuing
oxygen shortage, if left untreated for a sufficient period of
time, can cause damage or death (infarction) of heart muscle
Heart Attack Causes:
Heart attack rates are higher in association with intense exertion, be it psychological stress or physical exertion, especially if the exertion is more intense than the individual usually performs.
- Acute severe infection, such as pneumonia, can trigger heart attack
- High blood pressure
Heart Attack Symptoms:
The onset of symptoms in heart attack is usually gradual, over several minutes, and rarely instantaneous:
- Chest pain is the most common symptom of acute heart attack and is often described as a sensation of tightness, pressure, or squeezing.
- Shortness of breath
- Excessive form of sweating, Weakness, Light-headedness, Nausea, Vomiting, and Palpitations.
- Loss of consciousness
Heart Attack Prevention :
- Keep blood cholesterol levels in check. Everyone adult should know what his or her cholesterol level is.
- Eat a well-balanced diet. Avoid eating large amounts of fat and cholesterol in your diet because these can accelerate the progression of hardening and clogging of coronary arteries.
- Drink alcohol in moderation, if at all.
- Quitting smoking is the single best lifestyle change you can make.
- Increase your physical activity. Start slowly if you need to, but try to reach the goal of at least 30 minutes of endurance exercise 3-5 times a week. Such exercises include walking, swimming, biking, and aerobics.
- Lose extra weight. Being overweight puts extra strain on the heart and blood vessels.
