The appropriate regimen of platelet inhibitors that should be used in patients with immune thrombocytopenia purpura (ITP; formerly called idiopathic thrombocytopenic purpura) who are undergoing percutaneous coronary intervention is unclear. We report the case of a patient with ITP who underwent two separate coronary interventions. The first involved the use of aspirin and a cutting balloon to treat obstructive disease of the left circumflex. When the patient presented with restenosis, he received eptifibatide, clopidogrel, and an intracoronary stent. He is currently 16 months removed from his second procedure and remains physically active without any anginal symptoms. Percutaneous revascularization in patients with ITP remains a challenge and this therapeutic approach, while ultimately successful in the patient, requires further validation.

Coronary artery disease remains a significant global health issue and is a leading cause of mortality. Dual antiplatelet therapy, including clopidogrel, is essential for preventing stent thrombosis after coronary artery stenting. This study assessed the comparative efficacy and safety of generic versus brand-name clopidogrel in a large Taiwanese cohort.

Clopidogrel, an anti-platelet drug, is used to prevent thrombosis after percutaneous coronary intervention. Clopidogrel resistance results in recurring ischemic events, with African Americans (AA) suffering disproportionately. The aim of this study was to discover novel biomarkers of clopidogrel resistance in African Americans using genome and transcriptome data.

We report the case of a 73-year-old male with a history of recurrent coronary interventions who presented with progressive angina and was diagnosed with a chronic total occlusion (CTO) of a heavily calcified and tortuous right coronary artery (RCA). Standard antegrade and retrograde techniques were attempted but failed due to the complexity of the lesion. A novel "Drag-Drill" technique was employed, utilizing a retrogradely externalized RG3 guidewire as a rotational atherectomy wire, enabling successful rotational atherectomy and percutaneous coronary intervention (PCI).

Background: Thrombolysis in Myocardial Infarction (TIMI) risk score in patients with ST-segment elevation myocardial infarction (STEMI) is associated with major adverse cardiovascular events (MACE). This study aimed to develop a prediction model based on the TIMI risk score for MACE in STEMI patients after percutaneous coronary intervention (PCI).
Methods: We conducted a retrospective data analysis on 290 acute STEMI patients admitted to the Affiliated Hospital of Yangzhou University from January 2022 to June 2023 and met the inclusion criteria.
