Platelet activation is linked with thrombosis, inflammation or heart failure.
OBJECTIVE:
To establish clinical and analytical factors that may favor high mean platelet volume (MPV) and to determine if MPV levels favor major adverse cardiovascular events (MACE).
METHODS:
Stable CHD patients and a control population matched for age, sex and cardiovascular factors.
RESULTS:
658 CHD patients and 2092 controls were studied. Median age in CHD patients was 33 (25–41) year old with 56% of them being male. No significant differences were seen between MPV values and cardiac complexity (p = 0.308) nor between MPV values in the CHD and control groups (p = 0.911). CHD patients had significant lower platelet count and MPV levels than patients in the control group. In the binary logistic regression analysis NT-pro-BNP levels above 125 pg/ml, thrombocytopenia and having atrial fibrillation/flutter reached statistical significance as predictors of MPV levels above 11 fL. The Kaplan-Meier survival analysis showed no significance between MPV levels higher than 11 fL and MACE, cardiovascular mortality and thrombotic events in a median time follow-up of 6.7(1.5–10.6) years.
CONCLUSIONS:
Atrial fibrillation/flutter, heart failure and thrombocytopenia are predictors of high MPV levels. A MPV above 11 fL is not associated with MACE at a median follow-up time.
