Background: Nitric oxide (NO) exerts diverse effects on the cardiovascular system. Impairment of NO production plays a key role in cerebral and coronary artery spasm. We aimed to explore the predicting factors of radial artery spasm (RAS) and the association of eNOS gene polymorphism (Glu298Asp) with RAS during cardiac catheterization.
Methods And Results: 200 patients underwent elective coronary angiography through a trans-radial approach. The subjects were genotyped to the Glu298Asp polymorphism (rs1799983) on the eNOS gene by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). Our results showed that the subjects with the TT genotype and T allele were significantly more likely to develop radial artery spasms (OR = 12.5, 4.6, P < 0.001 respectively). TT genotype of eNOS Glu298Asp polymorphism, number of punctures, size of the radial sheath, radial tortuosity, and right radial access are independent predictors of radial spasm.
Conclusion: The eNOS (Glu298Asp) gene polymorphism is associated with RAS during cardiac catheterization in Egyptians. TT genotype of eNOS Glu298Asp polymorphism, number of punctures, size of the radial sheath, right radial access, and tortuosity are independent predictors of RAS during cardiac catheterization.

Pre-distance assessment from radial artery to lower extremity arterial lesion.
Int J Cardiovasc Imaging
January 2025
Department of Cardiovascular Medicine, Kyoto Prefectural University of Medicine, Kyoto, Japan.
Endovascular treatment (EVT) for patients with lower extremity artery disease is widely used as a less invasive alternative to surgical bypass. Recently, transradial artery intervention has gained popularity owing to its minimally invasive nature. The distance from the radial artery to the target vessel is critical for success; however, effective pre-assessment methods have not yet been established.

Radiology, The Children's Hospital of Philadelphia, Philadelphia, Pennsylvania, USA.
Background: We aim to share our experience of transradial access (TRA) for cerebral angiography and intervention in five patients ranging from 6 days to 7 months of age.
Methods: In this institutional review board-approved, retrospective case series, we reviewed all patients who underwent TRA for cerebral angiography with and without intervention. We describe three techniques for radial artery cannulation, namely: (1) bareback; (2) with a micropuncture sheath; and (3) with an intravenous catheter.
Feasibility and Safety of Distal Radial Artery Access with Recanalization of a Chronic Radial Artery Occlusion for Subsequent Coronary Angiography and Intervention.
Acta Cardiol Sin
January 2025
Department of Internal Medicine, Division of Cardiology, Kaohsiung Chang Gung Memorial Hospital and Chang Gung University College of Medicine, Kaohsiung, Taiwan.
Aims: This study aims to verify the feasibility and safety of percutaneous coronary intervention (PCI) after a distal transradial approach (dTRA) with radial artery occlusion (RAO) recanalization.
Methods: Between July 2018 and January 2022, 30 patients underwent PCI following attempted RAO recanalization via dTRA. Among these cases, the target radial arteries could not be recanalized in five patients, necessitating alternative vascular access.
The Effects of Local Heating on Facilitating Radial Angiography: A Randomized Controlled Trial.
Iran J Nurs Midwifery Res
November 2024
Student Research Committee, Nursing and Midwifery College, Isfahan University of Medical Sciences, Isfahan, Iran.
Article Synopsis
- The study explores how local forearm heating can improve the radial angiography process by making it quicker and more efficient for patients and healthcare professionals.
- The clinical trial involved 80 patients, comparing outcomes between those who received infrared heating before the procedure and those who did not.
- Results showed that patients who were heated experienced fewer complications and shorter procedure times, suggesting that using local heat can enhance patient comfort and the overall angiography process.
Coronary Intervention Outcomes in Patients with Liver Cirrhosis.
Curr Cardiol Rep
January 2025
Division of Cardiology, NYU Grossman School of Medicine, New York, NY, USA.
Purpose Of Review: This review assesses the outcomes of coronary interventions in patients with liver cirrhosis and coronary artery disease (CAD), focusing on the clinical challenges posed by cirrhosis-related hemodynamic and coagulopathic changes. It highlights essential considerations for managing these patients, who have an increased risk of adverse events during coronary procedures.
Recent Findings: Recent studies have shown that patients with liver cirrhosis undergoing PCI experience significantly higher mortality rates compared to non-cirrhotic patients, particularly in the context of STEMI and NSTEMI.
