Implication
Requires disease-specific NO approaches in CV care; leaves open precise therapeutic targeting for prospective trials.
Key Points
- To review the dual physiological and pathophysiological roles of nitric oxide synthesized by constitutive and inducible synthases across various cardiovascular disorders.
- Narrative synthesis examining experimental and clinical evidence on nitric oxide activity in hypertension, atherosclerosis, cardiomyopathy, and endotoxin shock.
- Endothelium-derived nitric oxide regulation varies by pathology, experiencing enhanced breakdown by superoxide radicals in atherosclerosis and showing variable production across hypertensive models.
- Overexpression of inducible nitric oxide synthase during endotoxaemia leads to excessive nitric oxide output, driving profound hypotension, catecholamine resistance, and cardiac dysfunction.
- Therapeutic strategies show disease-specific utility, with inhaled nitric oxide gas proposed for pulmonary hypertension and synthesis inhibitors emerging as targets for septic shock.

Patients and experimental models with cardiovascular diseases, including hypertension, atherosclerosis, pulmonary hypertension, coronary artery disease, cardiomyopathy, and endotoxin shock
This review highlights the diverse physiological and pathophysiological roles of nitric oxide across various cardiovascular conditions, suggesting potential therapeutic avenues such as NO inhalation for pulmonary hypertension and NOS inhibitors for endotoxin shock.
