Impact of blood transfusion on in-hospital myocardial infarctions according to patterns of acute coronary syndrome: Insights from the BleeMACS registry.

Background: Blood transfusions (BTs) may worsen the prognosis of patients affected by acute coronary syndromes (ACS), although few data detail their impact on short-term events according to clinical presentation (ST Segment Elevation Myocardial Infarction, STEMI vs. Non-ST Segment Elevation ACS, NSTE-ACS).

Methods: Patients undergoing percutaneous coronary intervention (PCI) for ACS, with data on BTs, were selected from the BleeMACS registry.

Laboratory aspirin resistance reversibility in diabetic patients: a pilot study using different pharmaceutical formulations.

Purpose: Aspirin resistance occurs most frequently in diabetic patients and is associated with poor prognosis. The purpose of this study was to evaluate the prevalence of aspirin resistance in a cohort of diabetic patients and whether it can be reversed using more bioavailable aspirin formulations.

Methods: Platelets function of 163 diabetic patients taking acetyl salicylic acid (ASA) 100 mg daily has been evaluated with PFA100 and VerifyNow.
