We report a 64-year-old Turkish man who presented with unstable angina pectoris. Coronary angiography revealed massive intracoronary thrombus, which completely occluded the distal part of the left circumflex coronary artery. The thrombotic segment and the rest of the coronary tree were free of atherosclerosis. The patient was treated with intravenous tirofiban, a glycoprotein IIb/IIIa inhibitor. A control angiography was performed one week later and showed total dissolution of the thrombus with tirofiban therapy.

Association between neutrophil to high-density lipoprotein ratio and no-reflow after coronary intervention: A cross-sectional study.

Inflammatory responses and lipid metabolism disorders are key components in the development of coronary artery disease and contribute to no-reflow after coronary intervention. This study aimed to investigate the association between the neutrophil to high-density lipoprotein ratio (NHR) and no-reflow phenomenon in ST-segment elevation myocardial infarction (STEMI) patients after primary percutaneous coronary intervention (PPCI). This study enrolled 288 patients with STEMI from September 1st, 2022 to February 29th, 2024, in the Zhengzhou Central Hospital Affiliated to Zhengzhou University.

Background: Despite fractional flow reserve (FFR)-guided deferral of revascularization, recurrent events in patients with diabetes or after myocardial infarction remain common. This study aimed to assess the association between FFR-negative but high-risk nonculprit lesions and clinical outcomes.
Methods: This is a patient-level pooled analysis of the prospective natural-history COMBINE (OCT-FFR) study (Optical Coherence Tomography Morphologic and Fractional Flow Reserve Assessment in Diabetes Mellitus Patients) and PECTUS-obs study (Identification of Risk Factors for Acute Coronary Events by OCT After STEMI and NSTEMI Patients With Residual Non- Flow Limiting Lesions).

Background: Due to the lack of a prior comprehensive review and meta-analysis, the relationship between monocyte count and thrombus load in ST-elevation myocardial infarction (STEMI) patients undergoing percutaneous coronary intervention (PCI) has not been adequately established.
Methods: This was a systematic review and meta-analysis of multiple cohorts (retrospective and prospective) and cross-sectional studies.We queried electronic databases (PubMed, Google Scholar, and Cochrane Central) from their inception to April 2022.
Impact of different glycoprotein IIb/IIIa inhibitor infusion routes on infarct size and microvascular obstruction in patients with high thrombotic risk ST elevation myocardial infarction.

Objective: Current guidelines recommend the use of glycoprotein IIb/IIIa (GpIIb/IIIa) inhibitors in patients with ST-segment elevation myocardial infarction (STEMI) only as a bail-out therapy. However, drug penetration to the jeopardised area may not be achieved due to impeded blood flow and increased microvascular resistance. Aim of our study is to investigate the impact of distal intracoronary GpIIb/IIIa inhibitor agent infusion in STEMI patients.

Background: Acute myocardial infarction during pregnancy is a rare condition with an incidence of 1 to 10 per 100,000 deliveries. ST-elevation myocardial infarction (STEMI) is dominating the clinical presentation. It is estimated that 29% of the patients had normal coronary arteries, and hyperthyroidism may be associated with coronary vasospasm.
