Heart is the major organ present in our human body. The heart muscle requires constant supply of oxygen-rich blood in order to nourish it, which is provided by the coronary arteries. In case of loss of blood supply by coronary arteries, it leads to the death of heart muscles, which is known as heart attack.
When the heart muscles die, the patient experiences chest pain, which spreads to other parts of the body such as neck, arms, jaws, ears etc.
There are different types of heart attacks. The most common are as follows:
heart attack
STEMI Heart Attacks:
Substandard MIAn ST-segment level Myocardial Infarction (STEMI) is a serious form of heart attack in which a coronary artery is completely obstructed and most of the heart muscles are incapable to get blood. “ST section elevation” represents a design that reveals up on an electrocardiogram. This type of heart attack needs immediate, urgent revascularization which regenerates blood circulation through the artery. This revascularization is obtained either with medication by means of thrombolytics (clot busters), which are given intravenously, or mechanically with angioplasty as a treatment using slim, flexible pipes known as catheters to start the closed artery.
These catheters are placed at the starting of the coronary arteries, and contrast dye is treated through them to allow the interventional cardiologist to collect pictures of any blockage caused in the coronary arteries. Some of the guidewires are then innovative beyond the blockage and the clot is pulled out and a little increase is started out to force the obstruction out of the way. A stent is a metal, capable pipe is often placed simultaneously to completely brace the cleared artery to allow blood vessels circulation leads to heart disease.
NSTEMI Heart Attacks:
A non-ST segment level myocardial infarction (NSTEMI) is a type of heart attack that does not display a change in the ST section level on an electrocardiogram and that outcome in harm to the heart of the patient. However, these sufferers will analyze favorably for the proteins known as troponin in their blood vessels that is launched from the heart muscles when it is broken. In NSTEMI heart strokes, it is likely that any coronary artery obstructions are limited or exist for short-term.
Treatment for an NSTEMI heart attack, which includes drugs and examination to check whether a blockage is present or not, so that it should be controlled with drugs only or eliminated through angioplasty or handled with cardiac bypass graft surgery.
