“…Как известно, сегментарный анализ диасто-лической функции лишён влияния преднагрузки и частоты сердечных сокращений (ЧСС), поэтому можно предполагать выявление более надёжных показателей диагностики дисфункции миокарда при ПОИМ [2,4].…”

“…Одним из широко используемых показа-телей для диагностики диастолической дисфункции является скорость раннего диастолического движения основания фиброзного кольца митрального клапана (Еm). По величине данного параметра и по соотноше-нию Е/Еm можно отличить нормальный и псевдонор-мальный типы диастолической дисфункции [1,2]. Выявить существенное отличие Em у наших пациен-тов с различной локализацией ПОИМ не удалось (табл.…”

“…Сегментарный анализ движения ткани длительное время служил единственным инструментом объектив-ной оценки локальной сократимости и расслабления ЛЖ [1][2][3]6]. Однако, результаты проведенного исследования не позволили установить локализацию ПОИМ по пока-зателям сегментарной скорости движения ткани в иссле-дуемых группах больных (табл.…”

“…Согласно современ-ным представлениям нарушение функции расслабле-ния влияет на прогноз больных и развивается одновре-менно со снижением сократимости левого желудочка (ЛЖ) [1]. Известно, что диастолическая функция -это результат сочетания процессов активного рассла-бления и пассивного наполнения ЛЖ [2]. Общеприня-тая диагностика диастолической дисфункции прово-дится по показателям трансмитрального потока крови (ТМПК) и кровотока в лёгочных венах [1].…”

Aim.Comparison of diagnostical abilities of tissue Doppler (tD) and speckle tracking (St) for assessment of segmental diastolic dysfunction in postinfarction focal changes of myocardium (PIFC) of LV. Material and methods. totally, 137 CHD patients studied. In analysis of tD and St we assessed peaks of early and delayed transmitral LV fillings. Assessment of transmitral parameters of diastolic dysfunction was done with common approach. Results. the study showed that in PIFC persons there is no significant differences by most of transmitral flow parameters and tD. Strain rate assessment of myocardial deformation and St led to conclusion on mostly delayed filling peak decrease, which is one of the signs of segmental diastolic dysfunction of the LV in PIFC.Conclusion. tD and St make it to reveal covert disorders of diastolic LV relaxation in PIFC patients with absence of diastolic dysfunction criteria by tMBF.

“…4 Diastolic dysfunction (DD) is the inability of the left ventricle (LV) to fill during rest or exercise, to a normal end-diastolic volume without an abnormal increase in LV end diastolic pressure (LVEDP). 5 LVDD can progress to symptomatic heart failure. 6 In DD, the abnormality in LV relaxation and/or compliance (i.e.…”

BACKGROUND India has world's second largest number of diabetics. Much of the excess mortality among diabetics is because of cardiovascular diseases, including heart failure. Left ventricular diastolic dysfunction (LVDD), the earliest subclinical manifestation of diabetic cardiomyopathy, can worsen to heart failure. Some studies reported relation between LVDD and hyperglycaemia. There are no such studies on Keralite population. Ethnic variations occur in susceptibility to diabetes mellitus and cardiovascular diseases. Our study aims to examine whether LVDD in Keralite diabetics is related to the glycaemic status reflected by HbA1c. METHODS This is a cross sectional analytical study. Thirty diabetics between 21-50 years of age without hypertension, obesity and other comorbidities were selected. Parameters of left ventricular diastolic function (Iso-Volumetric Relaxation Time, ratio of peak velocity of early filling phase to peak velocity of late filling phase, deceleration time and ratio of peak velocity of early filling phase to early diastolic mitral annular velocity) were assessed by echocardiography and pulse wave tissue Doppler imaging. Venous blood HbA1c% (glycated haemoglobin A) was estimated. RESULTS 54.5% of the diabetics had Left Ventricular Diastolic Dysfunction (LVDD). HbA1c levels accounted for 88% variance in LVDD. There was a strong correlation between LVDD and HbA1c levels. CONCLUSIONS There is a strong correlation between LVDD and hyperglycaemia, as reflected by high HbA1c levels. So, rigorous control of blood glucose levels is needed to prevent heart failure in diabetes mellitus.
