Platelet Aggregation, Thromboxane A2, Prostacyclin Generation and Platelet Sensitivity to Prostacyclin during the First Month after Myocardial Infarction
Key result
Myocardial infarction was associated with increased platelet aggregation, elevated thromboxane B and prostacyclin production, and significant platelet resistance to prostacyclin during the first month.

Implication
Supports early post-MI platelet monitoring; hypothesis-generating for resistance-targeted therapy and should not yet change practice.

Outcome
Platelet aggregation, plasma thromboxane A, prostacyclin concentration, and platelet sensitivity to prostacyclinsurrogate
The study demonstrates dynamic changes in platelet reactivity and prostacyclin sensitivity in the first month post-MI, providing a pathophysiological rationale for early and sustained antiplatelet therapy.
Cite This Study
Viigimaa et al. (1995) conducted an observational in Myocardial Infarction. Myocardial infarction vs. Chronic coronary artery disease patients and healthy persons was evaluated on Platelet aggregation, plasma thromboxane A, prostacyclin concentration, and platelet sensitivity to prostacyclin. Myocardial infarction was associated with increased platelet aggregation, elevated thromboxane B and prostacyclin production, and significant platelet resistance to prostacyclin during the first month.
