Myocardial and Arterial Stiffness – Important Determinant of NT-ProBNP at Development of Heart Failure in Survivors of Myocardial Infarction

Purpose of the study. Analyze the parameters of the interaction between the left ventricle and the arterial system in patients with chronic forms of coronary heart disease and to identify relationships with levels of proadrenomedullin (MR‑proADM) and N‑terminal precursor of the brain natriuretic peptide B (NT‑proBNP).Materials and methods.240 patients with chronic forms of coronary heart disease (median – 55,9 [43; 63] years) and Q‑forming myocardial infarction in the past were examined. Of these, 110 patients with myocardial infarction and preserved lef ventricular ejection fraction and 130 patients with ischemic cardiomyopathy. All patients were calculated parameters of lef ventricular‑arterial interaction and the determination in blood serum levels of MR‑proADM and NT‑proBNP.Results.In patients with ischemic cardiomyopathy, an increase in the lef ventricular‑arterial interaction index was detected (2,51 [1,18; 5,00]), which reﬂects a decrease in the functional abilities and efficiency of the heart. In patients with myocardial infarction and a preserved left ventricular ejection fraction, this indicator was in the range of normal values (0,78 [0,55; 1,07]), which indicates an eﬀective cardiac work. A study of MR‑proADM and NT‑proBNP levels demonstrated an increase in both groups (1,72 [1,56; 1,98] nmol/l and 779,3 [473; 2193] pg/ml in the group of patients with ischemic cardiomyopathy; 0,89 [0,51; 1,35] nmol/l and 246 [118; 430] pg/ml in the group of patients with myocardial infarction and preserved left ventricular ejection fraction), and the correlation analysis with left ventricular‑arterial coupling interaction parameters allowed identify statistically significant connections (in the group of patients with ischemic cardiomyopathy: with the level of MR‑proADM ‑ r=0,67, p=0,006, with the level of NT‑proBNP ‑ r=0,78, p<0,001; in the group of patients with myocardial infarction and preserved left ventricular ejection fraction: with MR‑proADM level ‑ r=‑0,52, p=0,024, with NT‑proBNP level ‑ r =‑0,38, p=0,037).Conclusion.The findings suggest a pathogenetic association between the biomarkers under study and the parameters of left ventricular‑arterial coupling interaction.

Taking into account the increase in the level of cardiovascular diseases in recent decades, the clinician faces the task of attempting to make the fastest possible diagnosis of the pathology at its earliest stages. That is why the aim of our work was to identify the main groups of biological markers, and to separate the role of each of them in the assessment of the risk of development, progression and possible complications of cardiovascular diseases. We have given the main working classification of markers of cardiovascular processes with the allocation of their main types, as well as the basic criteria for the “ideal” biological marker. Finally, an attempt was made to structure biomarkers depending on their molecular mechanisms of pathogenesis in the development of a particular pathology. All these data should help the clinician at the stage of early diagnosis of cardiovascular disease.
