Heart Attack
Heart attack occurs when blood flow to an area of heart muscle get blocked. If the blood flow is not restored quickly, that area of heart muscle gets damaged due to lack of oxygen and start to die.
Heart attack is a major killer of both men and women in the Universe. But the positive things are today excellent treatments are available for heart attack that not only save lives and also prevent disabilities. Treatment gives excellent results if started within 1 hour of the beginning of symptoms.
Heart attacks can occur mostly due to the condition called coronary heart disease. In coronary heart disease, a fatty substance called plaque start builds up for years on the inside walls of the coronary arteries that supply blood and oxygen to the heart. Over time, an area of plaque can crack, causing a blood clot to be attached on the surface of the plaque. If the clot is large enough, it can block mostly or completely the flow of oxygen rich blood.
At the time of a heart attack, if the blockage in the coronary artery is not cleared quickly, the heart muscle will start to die and replaced with a scar tissue. This damage to the heart may not be obvious, or it may cause other severe heart problems.
Other severe heart problems linked to heart attack are heart failure and arrhythmias or irregular heartbeats. Heart failure is the inability of the heart to pump enough blood throughout the body. Ventricular fibrillation is a serious arrhythmia that can cause even death if not treated properly and quickly.
Heart Attack can also be called as; Coronary thrombosis, Coronary occlusion, Acute coronary syndrome, Myocardial infarction or MI, Acute myocardial infarction or AMI.
