Controversy still surrounds the question, which antiplatelet drug should be added to aspirin in patients undergoing coronary stent implantation. The aim of the current study was to compare ticlopidine and clopidogrel in a consecutive series of patients with ST-segment elevation myocardial infarction (STEMI) treated with primary stenting. Our population is represented by 883 consecutive patients with STEMI undergoing primary stenting from April 1997 to October 2001. All clinical, angiographic, and follow-up data were prospectively collected. A total of 523 patients on clopidogrel were compared with 360 patients on ticlopidine after primary stenting. Except for age and statin therapy, no difference in demographic and clinical characteristics was observed between the two groups. Patients on clopidogrel had a higher rate of successful reperfusion (80.7% vs 73.1%, p = 0.008). No difference was observed between the two groups at both 30-day and 1-year follow-up. These data were confirmed after correction for age, successful reperfusion and statin therapy. This study shows no difference in long-term clinical outcome between clopidogrel and ticlopidine as adjunctive antiplatelet therapy in patients with STEMI undergoing stent implantation.

Background & Aim: The definition and clinical relevance of percutaneous coronary intervention (PCI)-related myocardial infarction (MI) has been a topic of significant debate and controversy. It has particularly garnered widespread attention recently due to a contemporary trend of including it as a component of primary end points in major trials. The study aimed to assess the clinical relevance of PCI-related MI (PMI) according to the Fourth Universal Definition of MI using a high-sensitivity troponin (hs-Tn) assay in a real-world setting.

Fibrosing mediastinitis is a rare chronic inflammatory condition characterized by excessive fibrotic process in the mediastinum. Although various infectious processes are more common causes, it can also be related to several malignancies. We report a case of a 28-year-old woman with fibrosing mediastinitis related to an aggressive primary gray-zone lymphoma causing complete occlusion of the superior vena cava (SVC) and the innominate veins.

In clinical practice, the impact of procedural or patient-related risk factors on 1-year clinical outcomes in patients receiving 1-month of dual antiplatelet therapy (DAPT) followed by P2Y12 inhibitor monotherapy after contemporary percutaneous coronary intervention (PCI) remains unclear. Using data from the multi-center REIWA registry which included patients treated with thin-strut biodegradable polymer drug-eluting stent (BP-DES) and 1-month DAPT followed by P2Y12 inhibitor monotherapy, we assessed the primary endpoint (a composite of cardiovascular death, myocardial infarction, definite stent thrombosis, ischemic or hemorrhagic stroke, and major or minor bleeding) in patients with and without procedural (treatment of three vessels, three or more lesions, three or more stents, bifurcation with two stents, long stenting, and target of chronic total occlusion) and patient-related risk factor (renal insufficiency, anemia, peripheral vascular disease, prior or current history of heart failure and advanced age of ≥ 75 years). Among the 1,202 patients who underwent complete revascularization by PCI, 276 (23.

Background: Stroke requires timely intervention, with carotid endarterectomy (CEA) and carotid artery stenting (CAS) increasingly used in select acute carotid-related stroke patients. We aimed to build a model to predict neurologic functional independence (modified Rankin scale, mRS ≤ 2) in this high-risk group.
Study Design: We analyzed data from 302 stroke patients undergoing urgent CEA or CAS between 2015 and 2023 at a tertiary Comprehensive Stroke Center.
