Abstract

background: Recent epidemiological studies have demonstrated that nearly half of allpatients with heart failure (HF) have preserved left ventricular ejection fraction(HFPEF). Thereby it is mandatory to include other hemodynamic indices in the traditional evaluation of the systolic function of the heart beside the EF.Aim of the study was to assess the occurrence of subclinical systolic dysfunction in hypertensive patients with diastolic dysfunction referred for echocardiograph assessment of left ventricular function in a hospital.Methods: 30 patients were recruited from the Echocardiography lab. The analysis of diastolic dysfunction was based on the E/A ratio using PW- Doppler echocardiogram. measurement of EF and SV by measuring end systolic and end diastolic dimensions of left ventricle by M-Mode guided 2D echocardiogram. Measurement of HR from ECG. calculation of SI. CO and CI were done.Results & Discussion: The percentages of parameters which were found below normal levels are as follow: SV: 33.3% (10 out of 30 patients). SI : 40%(12 out of 30 patients). CO: 20%(6 out of 30 patients) and CI:53.3%(16 out of 30 patients).Conclusion : EF is not enough in evaluation subclinical systolic impairment in HT patient , CI should be used in concomitant with EF in traditional evaluation of any patient with suspicion of HF.

Abstract

Objectives:The aim of this study is to show the effects of left ventricular hypertrophy and geometric patterns on the left ventricular diastolic function in patients with essential hypertension. In addition, it’s aimed to identify whether the diastolic dysfunction is associated with systolic dysfunction. Finally, to determine the occurrence of the diastolic dysfunction in hypertensive patients with normal left ventricular mass.Patients and Methods: 135 subjects with essential hypertension of either sex attending echo unit were subjected to medical history, clinical examination, physical measurements, ECG, M-mode and Doppler echocardiography. They were classified as 43 treated hypertensives, and 92 untreated hypertensive patients. In addition to 32 healthy subjects served as control group. Results: The results of this study showed that untreated stage II hypertensive patients have more changes in left ventricular mass and geometry and, hence, a higher percentage of diastolic dysfunction. There was a small percentage of patients having diastolic dysfunction despite they were without LVH. In addition, Doppler echocardiographic examination showed that hypertensive patients with left ventricular diastolic dysfunction were having a normal left ventricular systolic function. Conclusion: Left ventricular hypertrophy and geometric changes have an obvious effects on the Left ventricular diastolic function especially in untreated stage II hypertensive patients.

Abstract

Background and objective: Hypertension is a very common medical disorder, affecting nearly 40% of our population. Diastolic dysfunction is one of complications that happens and is regarded as a predictive of subsequent heart failure. The aim of this study was to determine the frequency of left ventricular diastolic dysfunction by echocardiography among hypertensive patients. Methods: This study involved 150 hypertensive cases (82 female and 68 male) age from 25-81 years old. Transthoracic echocardiography approach, using SIEMENS SONOLINE Omnia 2005 machine with the probe of p4-2 was used by the researcher. A comparative 150 normal non-hypertensive healthy adults with hypertensive patients are examined again by echocardiography. The parameter for the diastolic dysfunction measurement is E/A ratio. Results: It was found that 88 (58.7%) of hypertensive patients have diastolic dysfunction, while 4.9% of non-hypertensive group have diastolic dysfunction with significant statistical differences between both groups (P <0.001), who were age >60years have 79%, while age 25-35years old have 21% (P <0.001). Among left ventricular hypertrophy patients, 87.5%, versus 12.5% have diastolic dysfunction (P <0.001). Females are more liable for diastolic dysfunction, who have 70.7% than males who have 44.1% (P <0.001). Conclusion: Diastolic dysfunction is common among hypertensive patients, particularly among females, aged, and who have echocardiographic criteria of left ventricular hypertrophy, represent risk factors for diastolic dysfunction.

Abstract

Background: Obesity is a public health concern worldwide associated with significant health risks and comorbid conditions. Obesity might be a strong factor that can induce left ventricular systolic dysfunction and eventually cause heart failure independent to coronary artery disease or other morbidities. In uncomplicated obese subjects, diastolic dysfunction is caused by hemodynamic and metabolic factors.Objectives: To assess the left ventricular (systolic and diastolic) function in a sample of overweight and obese subjects using different Echocardiographic tools and exploring the percentage and type of diastolic dysfunction in those people.Subjects and methods: one hundred seven (107) normal adult males subjects with a mean age of (39.3± 7.5) years were involved in this study. The study was performed during the period from September 2012 until July 2013, at the echo unit of Ibn Al-Bitar hospital for cardiac surgery. Results: Regarding E/A ratio there were statistically significant decrease in the E/A ratio of Group 1(normal body weight) when compared with that of Group3(obese). Deceleration time(DT), Isovolumetric relaxation time(IVRT) and E/Vp ratio showed a statistically significant increase when comparing Group1 with Group3. Regarding velocity of flow propagation(VP) there were statistically significant decrease when comparing Group1 with Group2 and Group 1 with Group3. Higher percent of subjects in group1 developed normal diastolic function(44%), while higher percent of subjects who found to have impaired relaxation were those in group3(68%), also higher percent of subjects with pseudonormal type were found in group3(57%) when compared to group1& 2.Conclusion: The relationship between BMI and diastolic function parameters is continuous and independent of cardiovascular risk factors that cluster with obesity, such as hypertension, diabetes, and LV hypertrophy. The overweight status is already associated with an impairment of LV diastolic function, close to that observed in obese persons. Keywords: obesity, overweight, diastolic dysfunction.

Abstract

Background: Left ventricular hypertrophy and diastolic dysfunction are considered to be an important risk factor for cardiovascular morbidity and mortality in asymptomatic hypertensive patients. At the bedside, left ventricular geometric remodeling and diastolic dysfunction in hypertension can not be diagnosed without echocardiography which is a useful adjunct to the medical history, physical examination, ECG, and chest radiography. Hence, it provides an opportunity for good management and prognosis of what appears to be preclinical hypertensive complication. Subjects and Methods: 127 subjects with essential hypertension of either sex attending echo unit were subjected to medical history, clinical examination, physical measurements, ECG, M-mode and Doppler echocardiography. They were classified as 46 treated hypertensives where they were on regular antihypertensive medication, and 81 untreated hypertensive patients. In addition, they were sex and age matched to 39 healthy subjects who served as control group. Results: The results of this study revealed that hypertensive patients especially those with stage II hypertension were prone to develop left ventricular hypertrophy (LVH) of concentric geometric pattern and diastolic dysfunction. However, small percentage of those patients found to have diastolic dysfunction despite they were without LVH. In addition, Doppler echocardiography clarify that hypertensives with abnormal transmitral inflow profile; of left ventricular impaired relaxation pattern suffered left ventricular systolic dysfunction. Moreover, in this study there was no evidence of pseudonormal transmitral inflow filling pattern which is excluded after Valsalva maneuver. Conclusion: There is a strong association between left ventricular hypertrophy and diastolic dysfunction which was more common in patients with stage II hypertension. However, left ventricular diastolic dysfunction is usually follows left ventricular hypertrophy, but it still may proceed especially in those patients with left ventricular hypertrophy (LVH) of concentric geometric pattern. In addition, left ventricle diastolic dysfunction is not necessary coincide with the development of systolic dysfunction, namely normal ejection fraction and fractional shortening. Keywords: Hypertension, Left Ventricular Hypertrophy (LVH), Diastolic dysfunction, Valsalva maneuver.

Abstract

ABSTRACT:BACKGROUND: The left ventricular diastolic dysfunction (LVDD) in asymptomatic patients with polycystic ovarian syndrome (PCOS) has been documented by both pulsed wave Doppler and tissue Doppler echocardiography.OBJECTIVE: The aim of this study was to identify the earliest asymptomatic impairment of the left ventricular diastolic dysfunction in polycystic ovarian syndrome women.PATIENTS AND METHODS: This study is conducted by the Department of Physiology, College of Medicine, Al-Mustansiriya University in cooperation with the unit of Infertility and unit of Echocardiography at Al-Yarmook teaching hospital in Baghdad during the period from December 2015 to April 2017. A total number of 150 subjects were included in this study, 50 healthy subjects (control group) and 100 patients with polycystic ovarian syndrome with (mean age and standard deviation of 28.27 ± 7.27 years). Pulsed wave blood flow Doppler and tissue Doppler imaging were used for estimating left ventricular diastolic dysfunction.RESULTS: 11% of the 100 PCOS women showed evidence of left ventricular diastolic dysfunction through impairment of mitral valve annular velocities and in the filling velocities of the left ventricle by pulsed wave Doppler, the ratio of peak early (E) filling velocity to the late (A) filling velocity (E/A ratio) was significantly lower in polycystic ovarian syndrome women with left ventricular diastolic dysfunction (0.780.17). By TDI the ratio of early (e՛) mitral annular velocity to the late (a՛) mitral annular velocity (e՛/a՛ ratio) was significantly reduced in polycystic ovarian syndrome women with the left ventricular diastolic dysfunction. Body mass index, waist circumference, waist-to-hip ratio, fasting blood sugar, fasting insulin, serum cholesterol, serum triglycerides, low density lipoprotein, very low density lipoprotein and homeostasis model assessment of insulin resistance were higher in polycystic ovarian syndrome group with left ventricular diastolic dysfunction.CONCLUSION: Diastolic dysfunction can develop early in patient with PCOS, and might be an early signal for cardiac involvement in this patient population..

Abstract

Background: The left ventricular diastolic dysfunction in asymptomatic patients with type 2 diabetes mellitus (T2DM) has been documented by tissue Doppler echocardiography.Objectives: The aim of this study was to look for the value of tissue Doppler imaging (TDI) in detecting LV diastolic dysfunction in type 2 diabetic patients.Patients and methods: This study is conducted by the department of physiology, college of medicine, Al-Mustansiriryah University in cooperation with the unit of Echocardiography at Al-Yarmouk Teaching Hospital in Baghdad during the period from November 2013 to July 2014. A randomized controlled non-invasive echocardiography. A total number of 92 subjects were included in this study, about fourty six healthy subjects (control group) (with mean age of 47.07±7.6 years) and fourty six patients with T2DM (with mean age of 49.39±5.7 years). Pulsed wave blood flow Doppler and tissue Doppler imaging (TDI) were used in estimating (LV) diastolic dysfunction.Results: 69.6% of the 46 diabetic patients (41% were male and 59% were female) showed evidence of LV diastolic dysfunction through impairment in mitral valve annular velocities and in the filling velocities of LV. By TDI the ratio of early filling velocity to the average early mitral annular velocity (E/E` ratio) was significantly increased in diabetic patients compared with the control subjects (7.4±1.7 versus 6.4±1.3) (P<0.04), the ratio of early (E`) mitral annular velocity to the late (A`) mitral annular velocity (E`/A` ratio) was significantly reduced in diabetic patients compared with control subjects (0.8±0.3 versus 1.02±0.3) (P<0.004). The E` average velocity was significantly reduced in diabetic patients (8.9±1.9 cm/sec) versus (10.7±1.6 cm/sec) in control group (P<0.0001). While by pulsed wave Doppler the ratio of the peak early (E) filling velocity to the late (A) filling velocity (E/A ratio) was significantly reduced in diabetic patients (0.9±0.3) versus (1.17±0.4) in control group (P<0.0001), and lower E velocity in diabetic patients (63.7±13.4 cm/sec) versus (72±19.9cm/sec) in control subjects (P<0.01). By TDI the study revealed that 69.6% of the asymptomatic type 2 diabetic patients have LV diastolic dysfunction, while by pulsed wave Doppler echo there was only 56.5% of diabetic patients have LV diastolic dysfunction. This would allow us to detect diastolic abnormalities in 12 subjects (13% of this sample study and 22.6% of LV diastolic dysfunction patients diagnosed by TDI) who would otherwise have been classified as normal by pulsed wave Doppler flow analysis alone. The mean duration of DM was 7.6±6.4 year. The study also revealed that the duration of DM was positively correlated with A velocity (r=0.29, p=0.048), fasting blood sugar (FBS) was negatively correlated with A velocity (r=-0.39, p=0.008).Conclusion: LV diastolic dysfunction can be evidenced by TDI in type 2 diabetic patients, even in the presence of a normal cardiac function with conventional echocardiography and asymptomatic diabetic patients. TDI is a valuable tool and it is more sensitive and more specific in detecting LV diastolic dysfunction in asymptomatic normotensive diabetic patients with non significant features on conventional echocardiography.

Abstract

Background: Left ventricular diastolic dysfunction (DD) is considered the first stage of diabetic cardiomyopathy; it occurs in absence of coronary artery disease, hypertension or valvular heart disease &can precede the systolic dysfunction in these patients.Objectives of the study: The purpose of this study is to assess the diastolic function in diabetic patients of both types 1&2 using conventional, Doppler echocardiograghy and tissue Doppler imaging, and to reveal the impact of age, gender & duration of diabetes on prevalence and grading of DD.Patients and methods: This is an observational case control analytic study in which 100 persons were enrolled, 50 of them were diabetic patients, and the other 50 were age, sex matched healthy control subjects. In both groups` systolic and diastolic functions were assessed by conventional, Doppler and tissue Doppler echocardiography. Results: Among the 50 patients, 27 (54%) of them were females and 23 (46%) were males, 27 (54%) of them were type1 diabetes and 23(46%) were type2 diabetes. Control group consisted of 50 subjects including 24(48%) females and 26(52%) males. Patient’s age ranges from 15 to 70 years with mean age (39±16.09), control subject’s age ranges from 15 to 72 years with mean age (37.64±14.53).There was significant relationship between aging and prevalence of DD (P value=0.02).Gender not related to prevalence of diastolic dysfunction. There was significant decrease in E/A ratio between both groups (P value=0.0007), while E/É ratio between both groups was not significant. DD also was higher in type2 diabetes compared with type1 (P value<0.001).Diabetic duration has no impact on prevalence of DD.Conclusion: Diabetic patients have significant DD detected on both conventional and tissue Doppler echocardiography. Diastolic function is affected with increasing age, but not with gender. The diabetic cardiac changes as well as the echocardiographic parameters seem not to be affected with diabetic duration.
