Patients with coronary heart disease (CHD), neurocirculatory dystonia and acute myocardial infarction showed statistically significant, positive linear correlations between the levels of inosine and hypoxanthine as well as the total concentration in the arterial blood and the blood from the coronary sinus. The correlation analysis ascertained that CHD patients in the initial state exhibited a considerable extraction of inosine by the myocardium as compared to patients with neurocirculatory dystonia and that in electrically stimulated ischemia it was sharply reduced. Electrostimulation in the group of patients with neurocirculatory dystonia had no effect on the rate of inosine extraction. Acute myocardial infarction was related to a higher rate of inosine extraction and to inosine production in the myocardium, the latter being explained by the degradation of adenyl nucleotides in conditions of acute ischemia. It is outlined that the total level of inosine and hypoxanthine in the arterial blood of patients with acute myocardial infarction may indicate the severity of infarction while its variations over time may be prognostically valuable.

UI MeSH Term Description Entries
D007042 Hypoxanthines Purine bases related to hypoxanthine, an intermediate product of uric acid synthesis and a breakdown product of adenine catabolism.
D007288 Inosine A purine nucleoside that has hypoxanthine linked by the N9 nitrogen to the C1 carbon of ribose. It is an intermediate in the degradation of purines and purine nucleosides to uric acid and in pathways of purine salvage. It also occurs in the anticodon of certain transfer RNA molecules.

D009449 Neurocirculatory Asthenia A clinical syndrome characterized by palpitation, SHORTNESS OF BREATH, labored breathing, subjective complaints of effort and discomfort, all following slight PHYSICAL EXERTION. Other symptoms may be DIZZINESS, tremulousness, SWEATING, and INSOMNIA. Neurocirculatory asthenia is most typically seen as a form of anxiety disorder.

D003327 Coronary Disease An imbalance between myocardial functional requirements and the capacity of the CORONARY VESSELS to supply sufficient blood flow. It is a form of MYOCARDIAL ISCHEMIA (insufficient blood supply to the heart muscle) caused by a decreased capacity of the coronary vessels.
