METHOD FOR DIAGNOSING DIASTOLIC LEFT VENTRICULAR DYSFUNCTION TYPE II IN PATIENT WITH SINUS RHYTHM WITHOUT PRIMARY MITRAL REGULATION AND MITRAL VALVE STENOSIS

摘要

The invention relates to medicine and can be used in ultrasound diagnostics for the diagnosis of diastolic dysfunction of the left ventricle II (pseudonormal, moderate) type in a patient with sinus rhythm without primary mitral regurgitation and mitral valve stenosis. The objective of the invention is to optimize the diagnosis of left ventricular diastolic dysfunction of type II in a patient with sinus rhythm without primary mitral regurgitation and mitral stenosis. The problem is solved by a method for diagnosing diastolic dysfunction of the left ventricle type II in a patient with sinus rhythm without primary mitral regurgitation and mitral valve stenosis, which consists in determining the level of the N-terminal precursor of brain natriuretic peptide (NT-proBNP) in the blood serum, when performing transthoracic echocardiography in the pulsed-wave Doppler mode determines the ratio of the velocities of the peaks E and A of the transmitral blood flow (E / A), the ratio of the velocity of the peak E of the transmitral blood flow and the velocity of the peak of early diastolic movement of the medial part of the mitral annulus e 'in the mode of pulsed-wave tissue Doppler ultrasonography ( / e '), the rate of tricuspid regurgitation in continuous wave Doppler imaging, left ventricular ejection fraction (LVEF) and with NT-proBNP value more than 311 pg / ml, E / A value equal to 0.86-1.86, E / e 'equal to 9 or more, a tricuspid regurgitation rate of more than 2, 62 m / s, LVEF value of 53% or less, e 'value of 0.07 m / s or less, left atrial volume index value of more than 35.7 ml / m diagnose type II left ventricular diastolic dysfunction.
