How is a Heart Attack Treated?

Thrombolytic drugs ("clot-busters") are used to dissolve blood clots that are blocking blood flow to the heart. When given soon after a heart attack begins, these drugs can limit or prevent permanent damage to the heart. To be most effective, they need to be given within 1 hour after of the start of heart attack symptoms.
Angioplasty procedures are used to open blocked or narrowed coronary arteries. A stent, which is a tiny metal mesh tube, may be placed in the artery to help keep it open.
Coronary artery bypass surgery uses arteries or veins from other areas in your body to bypass your blocked coronary arteries.

EKG, which detects any heart rhythm (arrhythmia) or functional problems
Blood pressure
Pulse oximetry, which measures the amount of oxygen in the blood and provides an early warning sign of a low level of oxygen in the blood.

Medications used in treating heart attacks include:

Beta blockers to decrease the workload on your heart by slowing your heart rate. This makes your heart beat with less force and lowers your blood pressure. Some beta blockers are also used to relieve angina (chest pain) and in heart attack patients to help prevent additional heart attacks. They are also used to correct irregular heartbeat.
Angiotensin-converting enzyme (ACE) inhibitors to lower blood pressure and reduce the strain on your heart. They are used in some patients after a heart attack to increase survival rate and help slow down further weakening of the heart.
Nitrates, such as nitroglycerin, to relax blood vessels and stop chest pain.
Anticoagulants (an-ty-ko-AG-u-lants) to thin the blood and prevent clots from forming in your arteries.
Antiplatelet (an-ty-PLAYT-lit) medications (such as aspirin and clopidigrel) to stop platelets from clumping together to form clots. These medications are given to people who have had a heart attack, have angina, or who experience angina after angioplasty.
Glycoprotein IIb-IIIa inhibitors, which are potent antiplatelet medicines given intravenously to prevent clots from forming in your arteries.
Medicines to relieve pain and anxiety.
Medicines to treat arrhythmias (irregular heart rhythms), which often occur during a heart attack.
Oxygen therapy.

Echocardiogram. In this test, ultrasound is used to make an image of your heart that can be seen on a video monitor. It shows how well the heart is filling with blood and pumping it to the rest of the body.
Exercise stress test. This test shows how well your heart pumps at higher workloads when it needs more oxygen. EKG and blood pressure readings are taken before, during, and after exercise to see how your heart responds to exercise. The first EKG and blood pressure reading are done to get a baseline. Readings are then taken while you walk on an exercise treadmill or pedal a stationary bicycle. The test continues until you reach a heart rate set by your doctor. The exercise part is stopped if chest pain or a very sharp rise in blood pressure occurs. Monitoring continues for 10 to 15 minutes after exercise or until your heart rate returns to baseline.
