Brief Summary

Patients with intra-aortic balloon pumps (catheters placed in the groin connected to a pump which assists the heart by opening and closing a balloon in the aorta, thereby decreasing the work of the heart and improving blood flow to the coronary arteries) often receive intravenous (IV) heparin (a "blood thinner") to prevent circulation problems in the leg (where they are inserted). When intra-aortic balloon pumps were initially developed, the catheters were larger than the catheters used today. Due to the large size of the catheter and the material used to make the catheter, it was thought that intravenous heparin would prevent poor blood flow to the leg that contained the temporary catheter. Intravenous heparin, however, has never been proven to maintain good blood flow in these patients. The catheters used with intra-aortic balloon pumps are now smaller in size and made of a material that is less likely to produce blood clots. It is not clear that heparin is needed with intra-aortic balloon pumps. Bleeding complications associated with intra-aortic balloon pumps may be decreased if heparin is not used. In 2004, 99 patients received intra-aortic balloon pumps in the cardiac catheterization labs at William Beaumont Hospital. These patients received intravenous heparin and experienced a large number of bleeding complications (27 patients required a blood transfusion). This study will help the investigators to clarify if heparin should or should not be routinely used in patients with intra-aortic balloon pumps.

Outcome Measures

Primary Outcomes (3)

  • Minor Ischemia (Decreased Blood Flow) During the Index Hospitalization

    Count of participants with decreased arterial flow in lower extremity as presented by diminished pulse that resolves with balloon removal, and not resulting in any impairment of body function

    0-4 days post surgery

  • Major Ischemia (Decreased Blood Flow) During the Index Hospitalization

    Count of participants with loss of Doppler signal or sensation or abnormal skin temperature, mottling or pallor in lower extremity requiring surgical intervention; or other major ischemic events including ischemic stroke; recurrent unstable ischemia (unstable angina, recurrent chest pain prompting definitive treatment such as re-percutaneous transluminal coronary angiography (PTCA), coronary artery bypass grafting (CABG), administration of thrombolytics); reinfarction including clinical symptoms or new ECG changes with creatine kinase (CK) elevation and positive creatine kinase-MB isoenzyme fraction; arterial thrombosis, embolus, dissection, or perforation; compartment syndrome; renal ischemia including new renal failure or need for dialysis; small bowel or splenic infarction; mesenteric or hepatic ischemia, or deep vein thrombosis.

    0-4 days post surgery

  • Major Bleeding During the Index Hospitalization

    Count of participants with hemorrhage associated with at least one of the following features as defined by the Thrombolysis in Myocardial Infarction (TIMI) Study Group criteria: Bleeding that results in a decrease in hemoglobin \>/= 5g.dL or a hematocrit decrease of \>/= 15% of baseline value; bleeding that is intracranial (confirmed by MRI or CT); bleeding that results in death.

    0-4 days post surgery

Secondary Outcomes (2)
