What causes a myocardial infarction
What causes a myocardial infarction. The main cause of myocardial infarction is an imbalance between the supply and demand for oxygen in the heart muscle tissue. The need for oxygen in the heart muscle tissue is high, but the supply (supply) of oxygen to the area is less.
The heart muscles need a supply of oxygen to continue pumping blood throughout the body. When the activity of the heart muscle increases, the need for oxygen also increases. If you don’t get oxygen for a long time, over time the heart muscle tissue can be damaged and be permanent.
The heart blood vessels that supply blood to the heart muscles are called coronary arteries. Decreased oxygen supply to heart muscle tissue can be caused by blockages in the coronary arteries called atherosclerosis, namely the presence of plaque in the holes in the heart’s blood vessels. So that the blood carrying oxygen cannot reach the heart muscle. Myocardial infarction is more common because it is caused by blockage of the heart blood vessels or ischemia.
What’s the reason I didn’t get any kind of warning?
Atherosclerosis itself is not accompanied by any symptoms. If a coronary artery becomes narrower and restricts blood flow, the blood vessels in the vicinity which serve the heart may expand to compensate. This could be the reason there aren’t any warning symptoms.
The network of enlarged blood vessels is known as collateral circulation. It assists in preventing certain patients from heart attacks by providing necessary blood into the heart. Collateral circulation may also be developed after a heart attack to assist in recovering the heart muscle.
Do I have a heart that is permanently damaged?
In the event of a heart attack and the heart muscle has lost blood supply starts to sustain injury. The severity of the damage to the muscle of your heart will depend on the extent of the region supplied by the artery that is blocked and the duration between the injury and treatment.
The damaged heart muscle from an attack on the heart heals by creating scar tissue. It generally takes about a week for the heart muscle to recover. The time frame is dependent on the severity of your injury as well as your healing rate.
The human heart is a robust organ. Although a portion of it might have been injured severely, however, the remainder of the heart continues to function. Because of the injury, your heart might be weaker and not be able to pump blood as efficiently as it does normally.
If you receive appropriate care along with lifestyle adjustments following an attack on the heart, any further injury can be prevented or even prevented.
