title: Mean platelet volume is not associated with coronary slow flow: a retrospective cohort study.
abstract: OBJECTIVE
  To investigate mean platelet volume (MPV) levels in patients with coronary slow flow (CSF).
  
  
  METHODS
  465 stable angina pectoris cases with angiographically normal coronary arteries were recruited [coronary slow flow group (n=76), control group (n=389)] in the observational retrospective cohort study. Clinical, biochemical and demographic variables including MPV were noted and coronary blood flow was assessed with TIMI frame count (TFC).
  
  
  RESULTS
  Gender, smoking, height, serum creatinine, uric acid levels, hemoglobin, waist/hip ratio, systolic blood pressure but not MPV were significantly different among groups. Independent predictors of CSF were height (p=.029) and serum uric acid level (p=.045). Gender, height, weight, hip circumference, systolic blood pressure, fasting blood glucose, serum urea, creatinine, uric acid levels, hemoglobin and platelet count were associated with mean TFC whereas independent predictors of mean TIMI frame count were height (p=.010) and serum uric acid level (p=.041).
  
  
  CONCLUSIONS
  Height and serum uric acid level but not MPV were independent predictors of both CSF and mean TFC.
