It is still controversial whether baseline thrombocytopenia is independently associated
with adverse events after percutaneous coronary intervention. We evaluated the influence
of baseline thrombocytopenia against ischemic, bleeding and mortality among the 19,353
patients whose baseline platelet counts were available in the pooled database from
the 3 studies in Japan. Baseline thrombocytopenia was classified as follows: mild,
≥100 and <150 × 109/L; moderate, ≥50 and <100 × 109/L; and severe, <50 × 109/L. Primary ischemic outcome measure was defined as composite of myocardial infarction
and ischemic stroke, and primary bleeding outcome measure was defined by the Global
Utilization of Streptokinase and Tissue Plasminogen Activator for Occluded arteries
trial as moderate or severe bleeding. There were 2,590 patients (13.4%) with baseline
thrombocytopenia comprising 292 patients (1.5%) with moderate/severe (moderate: 277
and severe: 15) thrombocytopenia and 2,298 patients (11.9%) with mild thrombocytopenia,
whereas 16,763 patients (86.6%) had no thrombocytopenia. During 3-year follow-up,
the adjusted risks of moderate/severe and mild thrombocytopenia relative to none were
neutral for primary ischemic outcome (hazard ratio [HR] 1.07 [95% confidence interval
[CI] 0.72 to 1.60], p = 0.74, and HR 0.93 [0.79 to 1.09], p = 0.37, respectively)
but were significantly higher for primary bleeding outcome (HR 2.35 [1.80 to 3.08],
p <0.001, and HR 1.20 [1.03 to 1.40], p = 0.02), and for mortality (HR 2.34 [1.87
to 2.93], p <0.001, and HR 1.26 [1.11 to 1.43], p <0.001). In conclusion, patients
with baseline thrombocytopenia, even a mild one, had a higher risk of bleeding events
and all-cause death, but not for ischemic events after percutaneous coronary intervention.
