Inhaled nitric oxide (iNO) is a pulmonary vasodilator that plays an important clinical ICU role. The administration of iNO is usually performed through an endotracheal tube, but spontaneously breathing patients might also benefit from iNO administration. The use of the non-invasive administration of iNO through high-flow nasal cannula (HFNC) allows for NO delivery in spontaneously breathing patients who still need supplemental oxygen and positive airway pressure. A simple method to administer NO through HFNC is described here using standard commercially available NO administration and HFNC.

Background: High-density lipoprotein (HDL) function, rather than its concentration, plays a crucial role in the development of coronary artery disease (CAD). Diminished HDL antioxidant properties, indicated by elevated oxidized HDL (nHDL) and diminished paraoxonase-1 (PON-1) activity, may contribute to vascular dysfunction and inflammation. Data on these associations in CAD patients, including acute coronary syndrome (ACS), remain limited.

Atherosclerosis (AS) is a chronic inflammatory disease driven by endothelial dysfunction, vascular smooth muscle cell proliferation, and insufficient resolution of inflammation. Nitric oxide (NO) plays a crucial role in vascular homeostasis by promoting endothelial cell proliferation, maintaining endothelial integrity, suppressing smooth muscle cell hyperplasia, and exerting potent anti-inflammatory effects. However, clinical application of NO is hindered by its short half-life, lack of targeting, and uncontrolled release.

Allergic rhinitis (AR) and chronic rhinosinusitis (CRS) are common respiratory conditions that significantly impact patient health and contribute to substantial healthcare burdens. While conventional treatments offer symptom relief, many patients continue to experience persistent symptoms, side effects, or resistance to standard therapies. This highlights the growing need for novel, non-invasive, and sustainable therapeutic strategies to manage chronic airway inflammation.

The vascular endothelium is responsible for regulating vascular tone, maintaining fluid homeo-stasis, and preventing platelet aggregation, exhibits regulatory properties in vasorelaxation and vasoconstriction - it produces, among others, nitric oxide and endothelin. The imbalance of vasoactive molecules leads to the loss of their function, known as endothelial dysfunction. Impaired endothelial function is observed in people with metabolic disorders, often preceding the onset of the disease by several years.

Heart failure with reduced ejection fraction (HFrEF) is a progressive condition that is associated with high rates of morbidity, frequent hospitalizations, and significant mortality. Despite advancements in guideline-directed medical therapy (GDMT), many patients continue to be at risk for worsening heart failure (WHF). Vericiguat is a novel soluble guanylate cyclase (sGC) stimulator that targets the impaired nitric oxide (NO)-sGC-cyclic guanosine monophosphate (cGMP) pathway.
