Overview

Supports genetic influence on epinephrine-induced platelet aggregation; leaves open relevance to cardiovascular outcomes or therapy.

Structured PICO

Is epinephrine-induced platelet aggregation influenced by genetic factors in healthy adult males?

P
Population
Healthy adult male twin pairs (17 monozygotic, 15 dizygotic)
I
Intervention
Epinephrine-induced platelet aggregation testing
C
Comparator
Monozygotic vs dizygotic twins
O
Outcome
Genetic influence on epinephrine-induced platelet aggregation (measured by intraclass correlations)surrogate

Genetic factors appear to influence epinephrine-induced platelet aggregation, though this phenomenon is not related to the number of alpha-adrenergic binding sites on platelets.
