Objective The purpose of the present study was to examine the relationship between thrombocytopenia at baseline and in-hospital outcomes in unselected patients undergoing elective percutaneous coronary intervention (PCI) in Japan.

Methods Among a total of 1,247 consecutive elective PCI-treated patients, patients with a baseline platelet count 150,000-449,000/μL and 50,000-149,000/μL were assigned to the normal platelet (n=1,009) and thrombocytopenia (n=226) groups, respectively. The thrombocytopenia group was further divided into the mild thrombocytopenia (100,000-149,000/μL, n=187) and moderate thrombocytopenia (50,000-99,000/μL, n=39) groups.

Results The angiographic success rate of PCI and in-hospital mortality rate did not differ to a statistically significant extent between the normal platelet and thrombocytopenia groups or between the mild thrombocytopenia and moderate thrombocytopenia groups, whereas the moderate thrombocytopenia group had a significantly higher rate of access site-related bleeding complications than the normal platelet group. According to a multivariate analysis, moderate thrombocytopenia was an independent predictor of access site-related bleeding complications.

Conclusion Among patients with mild to moderate thrombocytopenia, elective PCI might be feasible and effective in the short term; however, more attention should be paid to access site-related bleeding complications, particularly in patients with moderate thrombocytopenia.
