Stroke

Thrombus

Thrombolytic therapy is the use of drugs to break up or dissolve blood clots, which are the main cause of both heart attacks and stroke.

Tissue plasminogen activator; TPA; Alteplase; Reteplase; Tenecteplase; Activase thrombolytic agent; Clot-dissolving agents; Reperfusion therapy

Thrombolytic medications are approved for the immediate treatment of stroke and heart attack. The most commonly used drug for thrombolytic therapy is tissue plasminogen activator (tPA), but other drugs can do the same thing.

According to the American Heart Association, you have a better chance of surviving and recovering from a heart attack if you receive a thrombolytic drug within 12 hours after the heart attack starts.

Ideally, you should receive thrombolytic medications within the first 90 minutes after arriving at the hospital for treatment.

FOR HEART ATTACKS

A blood clot can block the arteries to the heart. This can cause a heart attack, when part of the muscle dies due to a lack of oxygen being delivered by the blood.

Thrombolytics work by dissolving a major clot quickly. This helps restart blood flow to the heart and helps prevent damage to the heart muscle. Thrombolytics can stop a heart attack that would otherwise be deadly.

The drug restores some blood flow to the heart in most patients. However, the blood flow may not be completely normal and there may still be a small amount of muscle damaged. Additional therapy, such as cardiac catheterization or angioplasty, may be needed.

Your health care provider will base the decisions about whether to give you a thrombolytic medication for a heart attack on many factors. These factors include your history of chest pain and the results of an ECG test.

Other factors used to determine if you are a good candidate for thrombolytics include:

• Age
• Gender
• Medical history (including your history of a previous heart attack, diabetes, low blood pressure, or increased heart rate)

Generally, thrombolytics will not be given if you have:
