Association of baseline hemoglobin A1c levels with bleeding in patients with non-ST-segment elevation acute coronary syndrome underwent percutaneous coronary intervention: insights of a multicenter cohort study from China.

Compared with the lower baseline HbA1c levels, the higher baseline HbA1c levels were associated with an increase in long-term bleeding risk in NSTE-ACS patients undergoing PCI, though higher baseline HbA1c levels were not associated with the higher risk in all-cause death.
