No-reflow is one of the major complications of primary percutaneous coronary artery intervention (pPCI) in the treatment of acute ST-segment elevation myocardial infarction (STEMI). Fibrinogen-to-albumin ratio (FAR) has currently emerged as a novel inflammatory marker to predict inflammation in chronic diseases. This study aimed to investigate whether admission FAR values predicts angiographic no-reflow and short-term prognosis in all STEMI patients. ⋯ Receiver-operating characteristics analysis revealed the cut-off value of admission FAR was a predictor of no-reflow with a sensitivity of 79.59% and a specificity of 69.42%. In multivariable Cox regression models adjusted for potential confounders, admission FAR values, and LVEF, hs-CRP was independently and positively associated with the 30-day all-cause mortality. Admission FAR was associated independently and significantly with angiographic no-reflow and short-term mortality in patients with STEMI undergoing pPCI.

Coronary catheterization by a distal radial approach at the site of the anatomical snuffbox has recently been reported to be both safe and useful. No data are available on the diameter of the distal radial artery (DRA) in Japan, and it is unclear whether the DRA is large enough to withstand the insertion of a conventional sheath by a traditional radial approach. We enrolled 142 patients who underwent coronary catheterization and evaluated the vessel diameter of the DRA using ultrasound. ⋯ We could perform coronary catheterization by a distal radial approach without major bleeding or adverse events, and there was no radial artery occlusion at the site of the anatomical snuffbox or the forearm. For coronary catheterization by a distal radial approach, we should evaluate whether there is sufficient vessel diameter using ultrasound before the procedure. In addition, this approach can be an effective option from the viewpoint of radial artery preservation.
