title: [Nitric oxide and coronary heart disease].
abstract: The NO system plays an important role in pathogenesis of coronary heart disease. Disturbances of reperfusion associated with myocardial infarction and post-infarction heart failure are shown to be related to reduced synthesis and biological availability of NO. Variations of activity of three NOS isoforms (eNOS, nNOS, and iNOS) in patients with ischemic heart disease are linked to altered expression of the respective genes. They correlate with the character and severity of myocardial dysfunction. Cardiotropic effects of the above isoenzymes depend on their subcellular localization, interaction between themselves and between NO and reactive oxygen species, disturbed NO/redox balance, and other factors. Enhanced NOS activity and NO level at the premorbid stage of coronary heart disease have important implications for the prevention and treatment of this condition.
