Infarction of the heart occurs when a coronary artery is blocked, preventing the oxygen-rich passage of blood to the heart. A heart attack is a medical emergency that treats immediately. The heart muscle is damaged when the blood supply to it is blocked or diminished. Heart muscle will begin to die if blood flow is unstored right away. Diagnosis for heart attack is advanced by cardiac enzymes.
Symptoms of heart attack:
The symptoms of a heart attack might vary widely from one person to another, depending on the individual. In the event of a massive heart attack, in which the heart block happens in the main artery, the symptoms are likely to be worse.
- The following are common heart attack symptoms:
- Pain in the chest (angina)
- Jaw or neck pain
- Arms, shoulders, or backaches or pains
- Stomach pains or choking sensations
- Breathing difficulties
- Sweating skin and a chilly sweat
- Vomiting or feeling queasy
- The feeling of dizziness or lightheadedness
- A heartbeat that is rapid or irregular
Sudden chest pain is the most typical indication of a heart attack, but not everyone feels it. Some people only experience moderate symptoms that develop over time, while others experience more severe symptoms.
Risk Factors of Heart Attacks:
In coronary artery disease (CAD), your arteries constrict and harden due to the accumulation of a fatty substance called plaque. Fat, cholesterol and other chemicals that can accumulate in the inner lining of your arterial walls are called plaque. Atherosclerosis, or “hardening of the arteries,” is the term used to describe this development. When a blood clot lodges in an artery that constrict by plaque, the supply of blood to your heart can be cut off or severely diminished. A coronary artery spasm, or tightening, is a less prevalent cause of heart attacks.
How is a heart attack diagnosed?
When you arrive at the hospital, you have to inform your symptoms and heart disease history. You will also be monitored and checked to see if you have a heart attack.
Initial tests may comprise the following items:
- The electrocardiogram is a test of the heart (ECG or EKG)
- Tests of the blood
It can identify irregular electrical impulses coming from your heart, signaling a heart attack in the process or evidence of a heart attack that has occurred in the past. During a heart attack, proteins or enzymes release into the bloodstream. Blood tests can detect these substances is called as cardiac enzymes.
Male vs. female symptoms of heart attacks:
While the symptoms of a heart attack might vary hugely between men and women, there are some fundamental variances. Weirder symptoms, such as weariness, sleep difficulties and are more common in women. Other symptoms include pain in the arms, back, neck, jaw, or stomach without chest discomfort. However, women may also experience indigestion or discomfort in their chest rather than actual physical pain. Females should be on the lookout for heart attack symptoms other than the conventional ones and should seek emergency medical attention if they have any concerns about them.
