Objectives: We evaluated the relationship between neutrophil to lymphocyte ratio (NLR) and slow coronary flow (SCF).
Methods: A total of 180 participants were recruited to the present study. Of all the participants, 82 patients were with SCF and 98 participants were with normal coronary arteries. Basal characteristics were recorded. Coronary flow was quantified by thrombolysis in myocardial infarction frame count.
Results: Basal characteristics were similar between the 2 groups. The NLR was significantly higher in the SCF group when compared to the control group (2.3 ± 0.8 and 1.5 ± 0.4 respectively, P < .001). In multiple logistic regression analysis, NLR remained as the independent predictor of SCF (P < 0.001).
Conclusions: Our findings showed that NLR was significantly higher in the SCF group when compared to the control group with normal coronary arteries. We also showed that NLR was related to the presence of SCF rather than the extent of SCF. Besides these findings, we also showed the NLR as an independent predictor of SCF.

Hemodynamic stabilization is crucial in managing acute cardiac events, where compromised blood flow can lead to severe complications and increased mortality. Conditions like decompensated heart failure (HF) and cardiogenic shock require rapid and effective hemodynamic support. Current mechanical assistive devices, such as intra-aortic balloon pumps (IABP) and extracorporeal membrane oxygenation (ECMO), offer temporary stabilization but are limited to short-term use due to risks associated with prolonged blood contact.

Vascular smooth muscle cells (VSMCs) and endothelial cells (ECs) act together to regulate blood pressure and systemic blood flow by appropriately adjusting blood vessel diameter in response to biochemical or biomechanical stimuli. Ion channels that are expressed in these cells regulate membrane potential and cytosolic Ca concentration ([Ca]) in response to such stimuli. The subsets of these ion channels involved in Ca signaling often form molecular complexes with intracellular molecules via scaffolding proteins.

Backgrounds: Due to the high mortality and hospitalization rate in chronic heart failure (HF), it is of great significance to study myocardial nutrition conditions. Amino acids (AAs) are essential nutrient metabolites for cell development and survival. This study aims to investigate the associations and prognostic value of plasma branched-chain amino acid/aromatic amino acid ratio (Fischer's ratio, FR) in patients with left ventricular ejection fraction (LVEF) ≤ 50%.

We compared chorioretinal microvascular of Slow Coronary Flow Phenomenon (SCFP) patients using Optical Coherence Tomography Angiography (OCTA) to healthy controls. We recruited 21 patients from September 2023 until January 2024 from two referral centers. We enrolled 21 age-sex-matched controls retrospectively.
