Key result

Acute myocardial infarction was associated with a large mean platelet volume and low count, present in over 60% of MI patients compared with 13% of ischaemic heart disease controls.

Why the study?

Is acute myocardial infarction associated with differences in mean platelet volume and platelet count compared to myocardial ischemia or asymptomatic controls?

Population

Patients with acute myocardial infarction, a control group with myocardial ischaemia but no infarction, and…

Main Result

Absolute Event Rate: 60% vs 13%

Large mean platelet volume and low platelet count are associated with acute myocardial infarction and may represent a major risk factor.

Cite This Study

Kishk et al. (1985) conducted a case-control in Acute myocardial infarction. Acute myocardial infarction vs. Myocardial ischaemia without infarction was evaluated on High platelet volume and low count. Acute myocardial infarction was associated with a large mean platelet volume and low count, present in over 60% of MI patients compared with 13% of ischaemic heart disease controls.
