A heart attack happens when the menstruation of oxygen-rich claret to a section of heart musculus all of a sudden becomes blocked and the heart tin't become oxygen. If claret flow isn't restored quickly, the department of heart muscle begins to die.
Heart attack treatment works best when information technology's given right after symptoms occur. If you remember you lot or someone else is having a heart attack, fifty-fifty if y'all're not sure, phone call ix–1–1 right away .
Overview
Centre attacks about often occur equally a result of ischemic heart disease, also called coronary heart disease or coronary artery disease. Ischemic heart affliction is a condition in which a waxy substance called Plaque builds up inside the coronary arteries. These arteries supply oxygen-rich blood to your heart.
When plaque builds up in the arteries, the status is called atherosclerosis. The buildup of plaque occurs over many years.
Eventually, an surface area of plaque tin rupture (pause open) inside of an artery. This causes a blood clot to class on the plaque's surface. If the clot becomes large plenty, it can mostly or completely block blood menstruation through a coronary artery.
If the blockage isn't treated quickly, the portion of heart muscle fed by the artery begins to die. Healthy eye tissue is replaced with scar tissue. This heart damage may not exist obvious, or it may crusade severe or long-lasting problems.
Heart With Muscle Damage and a Blocked Artery
Figure A is an overview of a center and coronary avenue showing impairment (expressionless heart musculus) caused by a heart set on. Figure B is a cross-section of the coronary artery with plaque buildup and a claret clot.
A less mutual cause of heart attack is a severe spasm (tightening) of a coronary artery. The spasm cuts off claret period through the artery. Spasms can occur in coronary arteries that aren't affected by atherosclerosis.
Heart attacks can be associated with or pb to severe health problems, such equally eye failure and life-threatening arrhythmias.
Heart failure is a condition in which the heart tin't pump plenty blood to meet the body's needs. Arrhythmias are irregular heartbeats. Ventricular fibrillation is a life-threatening arrhythmia that can cause expiry if not treated right away.

Diagnostic Tests
EKG (Electrocardiogram)
An EKG is a simple, painless test that detects and records the centre's electrical activeness. The test shows how fast the center is beating and its rhythm (steady or irregular). An EKG as well records the strength and timing of electrical signals as they pass through each part of the heart.
An EKG can show signs of heart impairment due to ischemic middle disease and signs of a previous or current center set on.
Blood Tests
During a center attack, heart muscle cells die and release proteins into the bloodstream. Blood tests can measure the amount of these proteins in the bloodstream. College than normal levels of these proteins advise a eye assault.
Commonly used blood tests include troponin tests, CK or CK–MB tests, and serum myoglobin tests. Blood tests often are repeated to bank check for changes over fourth dimension.
Coronary Angiography
Coronary angiography (an-jee-OG-ra-fee) is a test that uses dye and special ten rays to prove the insides of your coronary arteries. This test often is done during a heart assault to help observe blockages in the coronary arteries.
To get the dye into your coronary arteries, your md will use a procedure called cardiac catheterization (KATH-e-ter-ih-ZA-shun).
A thin, flexible tube chosen a catheter is put into a blood vessel in your arm, groin (upper thigh), or neck. The tube is threaded into your coronary arteries, and the dye is released into your bloodstream.
Special x rays are taken while the dye is flowing through the coronary arteries. The dye lets your doctor study the menstruation of blood through the center and blood vessels.
If your dr. finds a blockage, he or she may recommend a procedure calledpercutaneous (per-ku-TA-ne-u.s.a.) coronary intervention (PCI), sometimes referred to as coronary angioplasty (AN-jee-oh-plas-tee). This procedure can help restore blood catamenia through a blocked avenue. Sometimes a small mesh tube called a stent is placed in the artery to help prevent blockages later the process.

Clot-Busting Medicines
Thrombolytic medicines, besides chosen jell busters, are used to deliquesce claret clots that are blocking the coronary arteries. To work best, these medicines must be given within several hours of the start of center attack symptoms. Ideally, the medicine should be given as soon as possible.
Percutaneous Coronary Intervention
Percutaneous coronary intervention is a nonsurgical process that opens blocked or narrowed coronary arteries. A thin, flexible tube (catheter) with a airship or other device on the end is threaded through a blood vessel, usually in the groin (upper thigh), to the narrowed or blocked coronary artery. In one case in identify, the airship located at the tip of the catheter is inflated to compress the plaque and related clot confronting the wall of the artery. This restores claret flow through the avenue. During the process, the dr. may put a pocket-sized mesh tube chosen a stent in the avenue. The stent helps to keep the blood vessel open to prevent blockages in the artery in the months or years later on the procedure.

The National Heart, Lung, and Blood Constitute (NHLBI) leads or sponsors many studies aimed at preventing, diagnosing, and treating heart, lung, blood, and sleep disorders.
The study is comparing two strategies for claret transfusions in heart set on patients who have anemia—whether to give a blood transfusion when the hemoglobin level is less than 10 1000/dL, or to give claret only when the blood count is beneath eight g/dL. To participate in this study, y'all must be at least 18 years old, have anemia, and be hospitalized for a heart attack. The study is located in New Brunswick, New Jersey.
