[Effect of autologous platelet-rich plasma on heart infarction in sheep].

Abstract

OBJECTIVE:

Myocardial infarction is the most common cause of congestive heart failure. The objective of this work is to evaluate, in experimental animals, morphological and histological effects of the implantation of autologous platelet-rich plasma in infarcted heart sheep.

METHODS:

Twenty-four ewes were used, they were surgically infarcted through left thoracotomy and two coronary arteries were ligated (first and second diagonal). After coronary artery ligation three sheep died of ventricular fibrillation. Three weeks after coronary ligation, sheep were reoperated through median sternotomy. Normal saline solution was injected in the infarcted zone in 6 of them (control group) whereas platelet gel was injected in 15 of them. All sheep were euthanized at 9 weeks of evolution of the second surgery.

RESULTS:

Noteworthy is the formation of new vessels in hematoxylin-eosin-stained sections and factor viii in plasma rich in growth-factors (PRGF)-treated hearts.

CONCLUSIONS:

Injection of platelet growth factors, PRGF, in previously infarcted sheep hearts promotes mitogenesis and angiogenesis. The use of autologous PRGF is simple and safe, causing no toxicity or immune-inflammatory reactions.
