Ventricular Diastolic Dysfunction

Left ventricular diastolic dysfunction (LVDD) is any abnormality in the filling of the left ventricle and is conventionally evaluated by analysis of the relaxation driven phase, or early diastole. LVDD has been shown to be a precursor to heart failure and the diagnosis and treatment for diastolic failure is less understood than for systolic failure. Diastole consists of two filling waves, early and late and is primarily dependent on ventricular relaxation and wall stiffness.

The aim – to study the features of structural and functional remodeling of the left ventricle in patients suffering from arterial hypertension with concomitant hypothyroidism and to determine clinical and past medical history and laboratory factors associated with their development. Materials and methods. 50 patients suffering from hypertension with concomitant hypothyroidism were enrolled into the study. Depending on the level of thyroid stimulating hormone in the serum the examined patients were distributed into two groups of 25 patients with the compensated and 25 with decompensated course of hypothyroidism. The control group consisted of 30 patients with hypertension in which the pathology of the thyroid gland was excluded. The comparison of the main parameters of the echocardiography study of the myocardium has been performed depending on hypothyroidism compensation. Assessment of parameters of transmitral diastolic blood flow has been performed. A regression analysis has been conducted to detect the relation of clinical and past medical history factors and echocardiographic parameters with the development of diastolic dysfunction by E/A ratio. The values of central hemodynamics have been studied for evaluation of the contractile function of the myocardium. Results and discussion. According to the results of the echocardiography of both examined groups it has been found that the final systolic and stroke volume exceeded the parameters of the control group. The mean value of the left ventricle ejection fraction was statistically significantly lower than in the control group (p=0.004). The left ventricle myocardial mass in patients with hypothyroidism was statistically significantly greater than in the control group. It was proved that in patients, who were diagnosed with decompensated hypothyroidism, the mean value of the left atrium size to growth by the degree of 2.7 was statistically significantly higher than in the control group (p=0.01), whereas the average value of the ratio of the size of the left atrium to the surface area of the body had no statistically significant differences between the groups. It has been found that in both groups the proportion of patients with diastolic dysfunction in which the E/A ratio was less than 1.0 was higher than in the control group (р=0.01 and p=0.03, respectively). The independent factors of diastolic dysfunction of the left ventricle in patients with hypertension in the presence of hypothyroidism have been found. Conclusions. In the presence of decompensated hypothyroidism in patients with arterial hypertension, both with obesity and with normal body mass index, left ventricular mass indexes were significantly higher in comparison with a control group. Regardless of the compensation of the thyroid state in patients with arterial hypertension, the ejection fraction was significantly lower. According to regression analysis, independent factors for the development of diastolic dysfunction in patients with arterial hypertension and hypothyroidism with a body mass index ≥ 30 kg/m2 is the index of mass of the left ventricular myocardium, determined by the degree of 2.7, the level of total cholesterol to statistical significance – the level of office systolic blood pressure and the duration of hormone replacement therapy for hypothyroidism; with body mass index < 30 kg/m2 – age and left atrial index, determined by body surface area. For patients with arterial hypertension and reduced thyroid gland function, violation of the left ventricular myocardial relaxation is typical as evidenced by a higher proportion of patients with a decrease in E/A to less than 0.8 in these patients.

Dilated cardiomyopathy (DCM) is the most common form of cardiomyopathy and cause of cardiac transplantation in children and young adults; mortality is high among this patient population. However, mortality, clinical course, and illustrative echocardiographic data of DCM in children and adults are not well established. Our objective was to provide a research article of detailed descriptions of the incidence, causes, outcomes, related risk factors, and new echocardiographic criteria of risk of death from DCM. Our results showed that independent risk factors at DCM diagnosis for subsequent death or transplantation in children cohorts were older age, congestive heart failure, lower left ventricular ejection fraction (EF ≤ 25%), low global strain, significant mitral valve incompetence, pulmonary hypertension, diastolic dysfunction, right ventricular involvement, and cause of DCM (p< 0.001 for all). In adults, low ejection fraction (<30–35%), global peak systolic strain <-7.6%, increased EDV, ESV, LBBB, diastolic dysfunction, and left ventricle dyssynchrony were the main independent risk factors for major cardiac events and need for CRT or transplantation (p< 0.001 for all). Our conclusions were that in children and adults, DCM is a diverse disorder with outcomes that depend largely on cause, age, heart failure status at presentation, and echocardiographic parameters of the heart (systolic and diastolic function of left ventricle, pulmonary artery pressure, global strain, and valvular function of the mitral valve). This study will present new findings in the diagnostic area.

Abstract Funding Acknowledgements Grant of the Grant Agency of Charles University and grant of the Czech Health Research council Introduction Over 50% of patients treated by chronic haemodialysis programme die of cardiovascular diseases. Changes of heart structure and function can be detected by echocardiography. The most frequent changes are left ventricle hypertrophy (LVH) and its diastolic dysfunction. One of the considered contributing mechanisms is the hyperkinetic circulation. Purpose The aim of this study was to analyse the effect of high flow arteriovenous fistula (AVF) on eft ventricular hypertrophy and diastolic function. Materials and methods We included 30 patients with a high-flow arteriovenous fistula into the study, indicated for AVF blood flow reduction because of heart failure or hand ischemia. All the patients underwent echocardiographic examination and ultrasonographic measurement of AVF blood flow before and 6 weeks after the surgery. Results The AVF banding led to significant reduction of Qa (from 2977 ± 1408 to 1295 ± 610 mL/min; p ˂ 10-6, accompanied by significant decrease of cardiac index (from 4.34 ± 1.09 to 3.56 ± 0.90 L/min.m2). These findings were accompanied by significant reduction of left ventricle mass index (from 125 ± 31 to 116 ± 32 g/m2; p = 0.04) and by improvement of diastolic dysfunction grade (from 1.66 ± 0.67 to 1.14 ± 0.95; p = 0.03). The maximum velocity of tricuspid regurgitation decreased (from 3.1 ± 0.4 to 2.7 ± 0.5), and so did the left atrium volume index (from 47 ± 14 to 42 ± 15 mL/m2; p = 0.01). Conclusions LVH and diastolic dysfunction are frequent in haemodialysis patients; hyperkinetic circulation caused by high-flow arteriovenous fistula is one of the significant contributing mechanisms. Surgical reduction of AVF blood flow improved diastolic function of the left ventricle and reduced the hypertrophy in our patient population. AVF flow volume should be always considered during cardiological examination of haemodialysis patients.
