A heart Attack is a myocardial infarction, “Myo” means muscles, “cardial” means heart, and “infarction” means the death of tissue because of a lack of blood supply. It is a common disease in many countries. A heart attack happens every 40 seconds according to the Centers for disease control and prevention. In a heart attack, chest pain is a common sign but there are many severe and mild symptoms that also occur during a heart attack, e.g. lightheadedness, nausea and shortness of breath.
What Is a Heart Attack
A heart attack happens when part of the heart muscles does not get enough blood. If there is not sufficient oxygen-rich blood will flow to the heart. It occurs when blood flow to the heart is reduced or blocked. The blockage of the heart occurs due to the accumulation of fat, cholesterol and other substances in the heart (Artery- Blood vessels that distribute oxygen-rich blood to the entire body). It can cause damage to the affected area. As a result heart muscles will begin to die.
When the heart does not get enough blood and oxygen it can cause a high risk of heart failure and other serious complications.

Causes Of Heart Attack
The main cause of heart attack is coronary heart disease. Coronary heart disease happens due to the formation of plaques in the arteries which supply oxygenated blood to the heart. Fat, Protein, calcium and inflammatory cells accumulate in the arteries to form plaques. Generally, plaque formation in the arteries is called atherosclerosis.
There are mainly two types of heart attack:
Type-1: When plaque is hard on the outer shell cracks then it gets rapture and release cholesterol and other substance like platelets into the bloodstream. It can form blood clots and block the artery.
Type-2 In Type-2 heart attack heart does not receive oxygenated blood as heart muscles become starved for oxygen.
