Background And Objectives: The recently discovered myokine irisin has a proposed role in adipose tissue metabolism. The aim of this study was to evaluate the relationship between serum irisin level and the coronary artery severity in patients with stable coronary artery disease (CAD).
Subjects And Methods: Sixty-three patients who underwent coronary angiography (CA) diagnosed with stable CAD and twenty-six patients with normal coronary artery (NCA) were enrolled in the study. Stable CAD patients were divided into two groups as high synergy between percutaneous coronary intervention with taxus and cardiac surgery (SYNTAX) score (≥23) and lower SYNTAX score (<23). Serum irisin level measurement was carried out using human irisin colorimetric enzyme-linked immunosorbent assay (ELISA) commercial kit (AG-45A-0046EK-KI01, Adipogen, San Diego, CA, USA) as recommended by the manufacturer's protocol.
Results: The patients with stable CAD with a higher SYNTAX score (score ≥23) had significantly lower serum irisin levels (127.91±55.38 ng/mL), as compared the patients with a low SYNTAX score (score <23) (224.69±92.99 ng/mL) and control group (299.54±123.20 ng/mL). Irisin levels showed significant differences between all groups (p<0.001).
Conclusion: Serum irisin level is an independent predictor of coronary artery severity in patients with stable CAD.

Background: Obstructive sleep apnoea (OSA) may lead to heart rhythm abnormalities including bradycardia. Our aim was to ascertain clinical and echocardiographic parameters in patients with OSA in whom severe bradycardia was detected in an outpatient setting, as well as to evaluate the efficacy of CPAP therapy on heart rate normalization at the early stages of treatment.
Methods: Fifteen patients mild, moderate or severe OSA and concomitant bradycardia were enrolled.

Coronary artery disease remains a significant global health issue and is a leading cause of mortality. Dual antiplatelet therapy, including clopidogrel, is essential for preventing stent thrombosis after coronary artery stenting. This study assessed the comparative efficacy and safety of generic versus brand-name clopidogrel in a large Taiwanese cohort.

It is critical to appreciate the role of the tumour-associated microenvironment (TME) in developing strategies for the effective therapy of cancer, as it is an important factor that determines the evolution and treatment response of tumours. This work combines machine learning and single-cell RNA sequencing (scRNA-seq) to explore the glioma tumour microenvironment's TME. With the help of genome-wide association studies (GWAS) and Mendelian randomization (MR), we found genetic variants associated with TME elements that affect cancer and cardiovascular disease outcomes.

We report the case of a 73-year-old male with a history of recurrent coronary interventions who presented with progressive angina and was diagnosed with a chronic total occlusion (CTO) of a heavily calcified and tortuous right coronary artery (RCA). Standard antegrade and retrograde techniques were attempted but failed due to the complexity of the lesion. A novel "Drag-Drill" technique was employed, utilizing a retrogradely externalized RG3 guidewire as a rotational atherectomy wire, enabling successful rotational atherectomy and percutaneous coronary intervention (PCI).
