Why the study?

Does higher heparin dosage reduce acute platelet-thrombus deposition after arterial angioplasty in a porcine model?

Population

32 normal pigs (mean weight, 32.7 kg) undergoing bilateral carotid angioplasty

Comparison

Higher dose heparin regimens: Protocol 2 or… vs Protocol 1: single intravenous bolus injection…

Design

Preclinical

Follow-up

90 +/- 26 minutes

Key result

In a porcine angioplasty model, platelet deposition on injured arteries was 86.3, 56.2, and 37.7 x 10^6/cm2 for single bolus, double bolus, and bolus plus infusion heparin regimens, respectively.

Overview

Sustained heparin regimens may attenuate platelet deposition post-injury; hypothesis-generating for human angioplasty dosing.

Structured PICO

Does higher heparin dosage reduce acute platelet-thrombus deposition after arterial angioplasty in a porcine model?

P
Population
32 normal pigs (mean weight 32.7 kg) undergoing bilateral carotid angioplasty, sacrificed 90 +/- 26 minutes later to assess platelet deposition.
I
Intervention
Higher dose heparin regimens: Protocol 2 (two 4,000 unit boluses 40 minutes apart) or Protocol 3 (initial 4,000-unit bolus followed by an infusion of 4,000 units/hr)
C
Comparator
Protocol 1: single intravenous bolus injection of 4,000 units heparin 10 minutes before angioplasty
O
Outcome
111In-labeled platelet deposition on deeply injured (torn into the media) arterial segmentssurrogate

Higher and sustained heparin dosing regimens appear to reduce acute platelet deposition following arterial injury in a porcine angioplasty model.

Cite This Study

Heras et al. (1988) studied Arterial angioplasty (n=32). Heparin vs. Different heparin regimens was evaluated on 111In-labeled platelet deposition on deeply injured arterial segments. In a porcine angioplasty model, platelet deposition on injured arteries was 86.3, 56.2, and 37.7 x 10^6/cm2 for single bolus, double bolus, and bolus plus infusion heparin regimens, respectively.
