Overview on What Causes Heart Attack
Most of the time, heart attack happens as a result of CHD (Coronary Heart Disease) which is also known as coronary artery disease. CHD is a condition where a substance known as plaque builds up in the coronary arteries (arteries that supply blood rich in oxygen to your heart). When this plaque builds up in the arteries, it leads to a condition known as atherosclerosis. Eventually, a section of the plaque breaks open inside the artery and causes a blood clot to occur on the plaque’s surface. If the clot becomes big, it can completely block blood flow and if the blockage is not treated immediately, part of the heart muscle starts to die.
Another cause of a heart attack is what is called a coronary artery spasm (a serious tightening of the coronary artery). Coronary artery spasm cuts off the blood flow through the artery and occurs in coronary arteries that are not affected by atherosclerosis.
23 Major Warning Signs of a Heart Attack that You Should Know
Not all people who suffer a heart attack experience the same symptoms. According to research, men and women have different signs. However, there are 3 common signs of heart attack that both women and men experience.
1. Chest Discomfort
Normally, a heart attack involves pain or some sort of discomfort in the chest. The feeling of distress usually takes place for around 2 to 3 minutes and it may stop for a while and strike again sometime later. Heart attack discomfort can be experienced in different ways such as pressure in chest that makes you uncomfortable and a feeling as if someone is squeezing your chest inside. People who have suffered a heart attack before say it feels like the chest is full or have severe pain in the chest.
