Background: Spontaneous coronary artery dissection (SCAD) is an increasingly recognized cause of acute coronary syndromes (ACS) afflicting predominantly younger to middle-aged women. Observational studies have reported a high prevalence of extracoronary vascular anomalies, especially fibromuscular dysplasia (FMD) and a low prevalence of coincidental cases of atherosclerosis. PHACTR1/EDN1 is a genetic risk locus for several vascular diseases, including FMD and coronary artery disease, with the putative causal noncoding variant at the rs9349379 locus acting as a potential enhancer for the endothelin-1 (EDN1) gene.
Objectives: This study sought to test the association between the rs9349379 genotype and SCAD.
Methods: Results from case control studies from France, United Kingdom, United States, and Australia were analyzed to test the association with SCAD risk, including age at first event, pregnancy-associated SCAD (P-SCAD), and recurrent SCAD.
Results: The previously reported risk allele for FMD (rs9349379-A) was associated with a higher risk of SCAD in all studies. In a meta-analysis of 1,055 SCAD patients and 7,190 controls, the odds ratio (OR) was 1.67 (95% confidence interval [CI]: 1.50 to 1.86) per copy of rs9349379-A. In a subset of 491 SCAD patients, the OR estimate was found to be higher for the association with SCAD in patients without FMD (OR: 1.89; 95% CI: 1.53 to 2.33) than in SCAD cases with FMD (OR: 1.60; 95% CI: 1.28 to 1.99). There was no effect of genotype on age at first event, P-SCAD, or recurrence.
Conclusions: The first genetic risk factor for SCAD was identified in the largest study conducted to date for this condition. This genetic link may contribute to the clinical overlap between SCAD and FMD.

Background: Umbilical arterial catheterisation is a common intervention performed in the neonatal intensive care unit (NICU) especially in extremely preterm and extremely low birth weight neonates. Rarely catheter fracture or breakage can occur, leaving behind part of the catheter in the aorta. A handful of cases have been reported in the literature, with the majority being managed surgically.

The outcome of percutaneous coronary intervention (PCI) compared to coronary artery bypass grafting (CABG) is still controversial for patients with left main coronary artery (LMCA) disease. This multicenter cohort study aimed to evaluate the clinical outcomes of LMCA disease patients who underwent PCI or CABG. We reviewed 875 consecutive patients diagnosed with LMCA disease between January 2009 and December 2020 who underwent coronary revascularization by PCI (n = 404) or CABG (n = 471).

Background: Fractional flow reserve (FFR) for non-culprit lesions (NCLs) in patients with ST-elevation myocardial infarction (STEMI) can be influenced by temporary changes in microvascular resistance. Angiography-derived vessel fractional flow reserve (vFFR) has been tested as a less-invasive alternative.
Aims: The FAST STEMI II study aimed to assess the diagnostic performance of acute-setting vFFR vs.

Background: Current guidelines recommend clopidogrel in patients with chronic coronary syndrome (CCS) undergoing percutaneous coronary intervention (PCI), yet the comparative benefits are unclear.
Aims: The aim of this study was to evaluate the efficacy and safety of ticagrelor versus clopidogrel in patients with CCS undergoing PCI.
Methods: We searched PubMed/MEDLINE, EMBASE, CENTRAL databases from inception to February 15, 2025.

Background: Acute kidney injury (AKI) represents one of the most challenging and common complications encountered in critically ill patients admitted to intensive care units (ICUs) worldwide. This sudden deterioration in kidney function substantially contributes to morbidity and mortality in the intensive care setting, prolongs hospital stays, and increases healthcare costs.
Objective: The objective of this study is to study the clinical profile, etiology, complications, and outcomes of AKI in critically ill patients admitted to the medicine ICU.
