Prognostic significance of blood marker of hypertrophy- cardiotrophin-1 when carrying different variants of its gene in men with essential hypertension

Abstract

The aim: To improve diagnosis of essential hypertension with left ventricular hypertrophy and chronic heart failure in men citizens of Podillya region in Ukraine by determining the plasma levels of cardiotrophin-1 in patients with different CT-1 gene variants. Materials and methods: A total of 70 men with no signs of cardiovascular disease and 100 patients with essential hypertension were examined. Among those, 50 participants had hypertension and left ventricular hypertrophy. Other 50 patients had hypertension complicated by chronic heart failure. Results: It was established that in patients with essential hypertension the frequency of the pool of genotypes GA + AA is higher than the genotype GG (p <0.05). Plasma CT-1 levels ≥ 122,895 pg / ml can be used for early diagnosis left ventricular hypertrophy, and the cut-off level is ≥ 303.81 pg / ml (sensitivity 85.7%, specificity 92%) for screening diagnosis of essential hypertension complications in the form of chronic heart failure. Conclusions: In patients with essential hypertension of varying severity, the GA+АА genotypes of CT-1 gene was found to be dominant. They had higher levels of plasma concentration CT-1. The threshold levels of CT-1 for screening diagnosis of essential hypertension with hypertrophy and chronic heart failure in males (who were residents of the Podillya region of Ukraine) were evaluated.
