With reference to cardiac invalidism, spouses of heart attack victims often show mental distress over the patient's survival.
<h3>What is Heart Attack?</h3>
A heart attack occurs when the blood flow to the heart is severely restricted or blocked. The obstruction is often brought on by the buildup of fat, cholesterol, and other substances in the heart's (coronary) arteries. The fatty, cholesterol-containing formations are known as plaques. The process of plaque accumulation is known as atherosclerosis.
On rare occasions, a plaque may rupture, causing a clot to form and obstruct blood flow. A reduction in blood flow can damage or even destroy a portion of the heart muscle.
A heart attack is also known as a myocardial infarction.
In order to survive a heart attack, immediate treatment is necessary. Get emergency help if you think you're having a heart attack.
