Patients who undergo percutaneous coronary intervention (PCI) to the left main (LM) coronary artery in the setting of acute coronary syndrome (ACS) were not adequately studied in the era of modern PCI. We investigated early and long-term outcomes of these patients, especially those with a true LM bifurcation stenosis. The Left Main Intervention in Acute Coronary Syndrome (LIMACS) is a multicenter registry that enrolled patients who underwent PCI to unprotected LM disease in the setting of ACS using a drug-eluting stent.

- This study explores the link between ABO blood groups and the risk of early stent thrombosis in patients who underwent coronary interventions, focusing particularly on non-O blood groups and their association with cardiovascular issues.
- Among 10,714 patients, only 0.73% experienced early stent thrombosis, and while non-O blood groups weren't significantly linked, those with B-antigens (B and AB blood types) showed a higher risk for early thrombosis compared to O type.
- The findings suggest that B-antigen presence is a notable factor in early stent thrombosis risk, indicating a need for more research to understand the biological mechanisms behind this relationship.
Background: Preprocedural evaluation, including frailty estimation, is crucial in managing patients undergoing Transcatheter Aortic Valve Replacement (TAVR). This involves mandatory computed tomography (CT) scans for assessing body composition parameters. The impact of low bone mineral density (BMD) on TAVR outcomes remains unclear, especially when measured using both non-enhanced and contrast-enhanced CT scans.

This study aimed to investigate the association between body mass index and outcomes in patients with a suspected myocardial infarction with nonobstructive coronary artery disease (MINOCA).
Methods: Patients were recruited at Bergmannsheil University Hospital from January 2010 to April 2021.
Introduction: Coronary sclerosis is a risk factor for the progression to obstructive coronary artery disease (CAD). However, understanding its impact on the outcomes of patients with myocardial infarction and non-obstructive coronary arteries is limited. This study aimed to explore the prognostic influence of coronary sclerosis on in- and out-of-hospital events in troponin-positive patients with non-obstructive coronary arteries.
