Heart Disease and Clot Buster Drugs

Clot buster drugs, or thrombolytic therapy, are a type of heart medication given in the hospital through the veins (intravenous) to break up blood clots. Heart attack (caused by a blood clot in a coronary artery) and ischemic stroke (caused by a blood clot in an artery in the brain) are the two main conditions for which clot busters are used.

Rein In the Rage: Anger and Heart Disease

If a caller upsets you, do you hurl the phone across the room? Do you curse and blast the horn furiously if the driver in front of you takes three seconds to notice the green light? An angry temperament can hurt more than relationships -- anger and heart disease may go hand in hand, according to experts. "You're talking about people who seem to experience high levels of anger very frequently," says Laura Kubzansky, PhD, MPH, an assistant professor at the Harvard School of Public Health who...

  • To prevent the ongoing damage of heart attacks.
  • To prevent ongoing damage from ischemic stroke.
  • To break up blood clots in other blood vessels in the body.

It is important to know the signs and symptoms of stroke and heart attack and call for emergency help (9-1-1 in most areas) right away if you or someone you are with is experiencing them. The faster you receive treatment with thrombolytic therapy (if appropriate), the quicker blood flow will be restored to the area and the greater the chance to prevent long-term damage, or even death.

There are several drugs that have been developed to break up clots, such as:

  • Tissue plasminogen activator (TPA)
  • Tenecteplase
  • Alteplase
  • Urokinase
  • Reteplase
  • Streptokinase

 

Who Shouldn't Take Clot Busters?

Some people aren't able to take clot busters. Please tell your doctor if you have any of the following conditions:

  • Previous hemorrhagic stroke or bleeding in the brain
  • Known cerebral vascular lesion or tumor
  • Previous allergic reaction to a clot buster, or other allergies
  • Active bleeding (excluding your menstrual period)
  • Pregnancy
  • Uncontrolled high blood pressure
  • Bleeding disorder, or recent history of bleeding in any part of the body
  • Severe liver disease
  • Recent surgery (less than 2 weeks)
  • Recent trauma, falls, or blows to the head within the past 3 months
  • Recent CPR
  • Active peptic ulcer

 

Should I Be Concerned About Food and Drug Interactions With Clot Busters?

Certain drugs may increase your risk of bleeding if you are prescribed clot busters. Tell your doctor the names of all the medications, over-the-counter drugs, herbal medications, supplements, or vitamins you are taking. Examples of these medications include:

Also tell the doctor if you have received any clot busters in the past six months. Some thrombolytic medications cannot be given a second time within a six-month period.

What Are the Side Effects of Clot Busters?

As with any drug, there can be side effects with clot busters. Notify your doctor if you notice:

  • Bleeding or oozing from cuts or around the area of injection
  • Allergic reaction
  • Fever
  • Low blood pressure
  • Signs of bleeding from other sites within the body, such as blood in the urine, black tarry stools, nose bleeds, bleeding from the gums
  • Any additional unusual symptoms

Ask your doctor or nurse if you have any questions about thrombolytic medications.
