The problem of chronic heart failure (CHF) remains one of the most important for the health care of many countries of the world. Recently, interest in diastolic heart failure has increased, as the number of patients in whom symptoms of decompensation develop against the background of intact left ventricular function has increased [ 1 , 2 ]. According to the Euro Heart Survay HF Study (2001), the number of patients with diastolic CHF is 30% [ 3 ].
The high prevalence of diastolic heart failure dictates the need for early diagnosis and timely initiation of effective therapy.
Difficulties in identifying diastolic CHF in patients with concomitant pathology are very great. This is due to the fact that the minimal manifestations of diastolic heart failure are often "masked" by the symptoms of the underlying disease (essential hypertension, type 2 diabetes) and its complications.
In turn, the success and effectiveness of treatment of diastolic CHF is determined by early and timely diagnosis of structural and functional changes in the heart.
