The marker of adverse prognosis 1.5-anhydroglucitol in patients with coronary heart disease in the long-term period after planned myocardial revascularization.

AIM

Determination of the prognostic value of 1.5-anhydroglucitol (1.5-AG) for the development of cardiovascular events in patients with coronary heart disease (CHD) within a year after a planned percutaneous coronary intervention (PCI).

MATERIALS AND METHODS

A prospective study was conducted in Federal State Budgetary Institution Research Institute for Complex Issues of Cardiovascular Disease among 149 patients admitted to planned PCI in the period from 2016 to 2017. Criteria for inclusion in the study: age up to 70 years, angina I-IV functional classes or post-infarction cardiosclerosis, the presence of indications for planned PCI. -Exclusion criteria from the study: previous myocardial revascularization; prosthetic heart valves; decompensation of chronic heart failure, anemia of any degree; acute coronary syndrome in index hospitalization; exacerbation of somatic diseases. The results of the research were processed by Statistica Windows 6.0.

RESULTS

During the year after planned PCI, 39 (26.14%) cardiovascular events were registered in patients with CHD, of whom more than half of the cases (51.28%) were associated with the presence of indications for PCI of de novo. Lower levels of 1.5-AG were observed in the group of patients with cardiovascular events (p=0.000). When patients were divided according to median of the studied marker patients with a concentration of 1.5-AG less 20.96 μg/ml (before PCI) were more likely to have PCI after restenosis of the stent, compared with patients whose median concentration of this marker was higher (p=0.028). The logistic regression method revealed a significant direct relationship reflecting the prognostic value of lower concentration of 1.5-AG in relation to the development of cardiovascular events in patients regardless of the presence of carbohydrate metabolism disorders [OR 0.25 (0.10-0.62)].

CONCLUSION

According to the results of the study, the prognostic value of the concentration of 1.5-AG less 20.96 µg/ml was established in relation to the development of cardiovascular events in patients with CHD during the year after a planned PCI, regardless of the presence of carbohydrate metabolism disorders.
