Background: The coronary atrial circulation is the network of vessels that supply blood to the atria, originating from the left circumflex and right coronary arteries. Current descriptions of this arterial system are based on anatomical studies with a limited number of patients, predominantly male. In addition, there is a lack of consensus its angiographic nomenclature.

This study aimed to investigate the relationship between the restoration of coronary flow just before stent deployment and the final thrombolysis in myocardial infarction (TIMI) flow grade 3 in patients with ST-segment elevation myocardial infarction (STEMI) whose initial TIMI flow grade ≤ 1. In primary percutaneous coronary intervention (PCI), initial TMI flow grade ≤ 1 is closely associated with suboptimal final TIMI flow grade. We included 466 STEMI patients with initial TIMI flow grade ≤ 1 and divided into a restored flow group or an unrestored flow group according to the TIMI flow grade just before stent deployment.

Background: After percutaneous coronary intervention (PCI), patients at high bleeding risk (HBR) according to The Academic Research Consortium for High Bleeding Risk (ARC-HBR) criteria have increased risk for ischemic complications. The underlying cause is not well documented. The aim of this study was to assess the ischemic risk among ST-elevation myocardial infarction (STEMI) patients classified as HBR according to the ARC-HBR and to identify individual risk factors.

Cardiac allograft vasculopathy (CAV) is a major prognosis-limiting factor in patients undergoing orthotopic heart transplantation (HT). Due to the diffuse involvement of the coronary tree, CAV lesions are often not amenable to percutaneous coronary intervention (PCI), leaving coronary artery bypass grafting (CABG) and retransplantation as primary revascularization options. : The latest guidelines from the International Society for Heart and Lung Transplantation (ISHLT) recognize CABG as a viable option but with a downgraded strength of recommendation.

Objectives: The aim of the study was to evaluate young MI patients in terms of clinical characteristics and long-term outcomes.
Patients And Methods: This study is an observational research covering 221 patients <45 years old [16.
