Myocardial infarction is a significant cause of morbidity and mortality worldwide, resulting in millions of percutaneous coronary interventions being performed yearly. Coronary artery stents are, however, at risk of thrombosis, with a significant mortality rate. Stent thrombosis is, however, preventable using dual antiplatelets, barring other procedural or unique personal predisposing characteristics. Good communication with patients is indispensable in ensuring adherence to dual antiplatelet therapy, protecting the patient from stent thrombosis. This paper presents a patient who discontinued his dual antiplatelet therapy prematurely and developed stent thrombosis within a week after discharge, highlighting the importance of good communication in promoting adherence to an agreed management plan.

Patients presenting with acute coronary syndrome with ST-segment elevation myocardial infarction require rapid and decisive interventions to restore blood flow to the affected myocardium, minimizing ischemic damage. This case report is particularly unique because it involves a patient presenting with ST-segment elevation myocardial infarction, where the culprit lesion was an occluded coronary artery graft with an extensive thrombus burden. The complexity of this case necessitated a strategic shift to revascularize the chronically occluded native vessel instead of the graft.

Aim: To evaluate the safety of brachial artery (BA) sheath removal after heparin neutralization with a half dose of protamine immediately after percutaneous coronary intervention (PCI).
Methods: The clinical data of 209 consecutive patients who underwent PCI through the BA at Fu Wai Hospital between September 2019 and June 2024 were retrospectively collected. In group I, the brachial sheath was removed 4 h after the PCI procedure.

Background: Biodegradable polymer stents may reduce the risk of neoatherosclerosis and stent thrombosis. Limited data is available for biodegradable polymer sirolimus-eluting stent (BP-SES) and durable polymer drug-eluting stents (DP-EES) in chronic total occlusions (CTO).
Aim: This study was to evaluate healing patterns of BP-SES versus DP-EES in CTO at 3 and 13 months based on optical coherence tomography (OCT).

Background: In patients with post-thrombotic syndrome (PTS), stent recanalization of iliofemoral veins or the inferior vena cava can restore venous patency and improve functional outcomes. The risk of stent thrombosis is particularly increased during the first 6 months after intervention. The ARIVA trial tested whether daily aspirin 100 mg plus rivaroxaban 20 mg is superior to rivaroxaban 20 mg alone to prevent stent thrombosis within 6 months after stent placement for PTS.

Cardiovascular diseases (CVDs) remain the leading cause of death worldwide, and the most common form is coronary artery disease (CAD). Treatment options include coronary artery bypass surgery (CABG) or percutaneous heart intervention (PCI), but both have drawbacks. Bare metal stents (BMS) are commonly used to treat CAD; however, they lead to restenosis.
