Data related to the incidence and clinical outcome of acute myocardial infarction (AMI) in patients with preexisting coronary artery ectasia (CAE) are limited. We assessed whether infarct-related artery ectasia (EIRA) indicates an untoward clinical outcome in patients with AMI undergoing primary percutaneous coronary intervention (pPCI). Consecutive patients (n = 643) who presented with AMI and were treated with pPCI were analyzed retrospectively; 31 patients (4.8%) had EIRA. Patients who had EIRA were significantly younger and had higher incidence of hypertension, previous stroke, smoking, inferior wall AMI, and Killip score >1. Infarct-related artery ectasia was more frequent in the right coronary artery (RCA). Impaired epicardial arterial flow, thrombus burden score of infarct-related artery (IRA), impaired Thrombolysis in Myocardial Infarction (TIMI) Myocardial Perfusion Grade, and distal embolization were significantly higher whereas ST-segment resolution and collateral vascular development were significantly lower in patients with EIRA. Infarct-related artery ectasia was an independent predictor of adverse outcome (odds ratio: 0.197; 95% confidence interval [CI]: 0.062-0.633; P = .006).

BACKGROUND Coronary artery ectasia (CAE) is frequently present with coronary artery disease (CAD). However, it is not clear why some patients with CAD progress to CAE while others do not. The pathogenesis of CAE is still poorly elucidated.

Deregulation of micro-RNAs (miRNAs) may contribute to mechanisms of injury in the bicuspid aortic valve (BAV). Our objective was to investigate the expression of miRNAs in aortic tissue from patients who underwent aortic valve replacement for aortic stenosis and its relationship with aortic dilatation. The study included 78 patients, 40 with bicuspid aortic valve (BAV) and 38 with tricuspid aortic valve (TAV).

Erythromelalgia, a rare cutaneous pain syndrome, is characterized by acral burning pain and flushing, often alleviated by cold and rest. Primary erythromelalgia is caused by gain-of-function mutations of genes encoding for sodium channels, resulting in hyperexcitability of pain signaling neurons. Autoimmunity and hematologic dyscrasias such as thrombocythemia have been implicated in secondary erythromelalgia.

Background: Many studies have validated the use of antiplatelet or anticoagulant therapy in coronary artery ectasia (CAE) to reduce major adverse cardiovascular events (MACE); however, it is not completely known which group of these antithrombotic medications is more effective. The purpose of this systematic review and network meta-analysis was to evaluate the efficacy of different anti-thrombotic treatments in adult patients with CAE.
Methods: This systematic review and meta-analysis followed preferred reporting items for systematic reviews and meta-analyses (PRISMA) guidelines as well as PRISMA extension statement for reporting of systematic reviews incorporating network meta-analyses and adhered to a registered predetermined methodology noted in the prospective register of systematic reviews (PROSPERO) protocol.

Background: Coronary artery ectasias and aneurysms (CAE/CAAs) are among the less common forms of coronary artery disease, with undefined long-term outcomes and treatment strategies.
Aims: To assess the clinical characteristics, angiographic patterns, and long-term outcomes in patients with CAE, CAA, or both.
Methods: This 15-year (2006-2021) retrospective single-centre registry included 281 patients diagnosed with CAE/CAA via invasive coronary angiography.
