المستخلص: congestive heart failure,the majority of such patients have systemic hypertension. Recent studies have demonstrated Left Ventricular dyssynchrony among patients with heart failure and normal systolic function.The co - existence between Left Ventricular dyssynchrony and hypertension with normal systolic function (with no clinical evidence of heart failure), is less well understood.The Aim of study : To assess the Left Ventricular dyssynchrony among hypertensive patients with normal systolic function by using Tissue doppler imaging.To find out the associations between the LV dyssynchrony and other global echocardiographic findings like (LA volume index, LVmass index , LV sephericity and LV filling pressure E/E) .Patients and method Prospective case - control study conducted in Baghdad Teaching Hospital from 1st of June 2015 to 30th of May 2016 .Study included two groups of people, a 40 age_ matched healthy (control) group (group1) and 60 patients with established hypertension (group 2). A Complete 2 - D and TDI echocardiography studies with simulitnous ECG were performed for all patients. Examination involved LV septal and posterior wall thicknesses, internal dimensions, left atrial size, ejection fraction and tissue doppler derived waves velocities E', E/E.' Dyssynchrony was determined by measuring T - P max ( the maximal time difference from the onset of QRS to peak systolic velocity on TDI between any opposing LV wall in 3 apical views) .Results : The study included 40 age - matched control people, 27males (67.5%) and 13 females (32.5%) with a male to female ratio was 1.8 : 1, ranging from (42.4 - 58y) with mean age was (50.2 ±7.8y ) (group 1) and 60 hypertensive patients, 38 males (63.3%) and 22 females (36.7%) with a male to female ratio was 1.7 : 1, ranging from (48.5 - 66.5y) with mean age of (57.5± 9.0 y) (group 2) .Left Ventricular dyssynchrony was identified in 20 of 60 patients (33.3%) .Dyssynchrony had no significant association with age and BSA. Dyssynchrony was significantly associated with LA volume index (r = 0.61, p=0.001), LV mass index (r=0.52 ,p=0.001) , LV sphericity index (r= 0.5, p = 0.003) ) and LV filling pressure (r=0.6 , p value=0.001) . Dyssynchrony had significant negative correlation with ( E) velocity (r= - 0.7 ,P =0.001) .

المستخلص: Introduction : Coronary artery disease is characterized by atherosclerosis in the epicardial coronary arteries. The reduction in coronary artery flow may be symptomatic or asymptomatic, occurs with exertion or at rest, and culminate in a myocardial infarction or angina, depending on obstruction severity and the rapidity of development. Speckle - tracking echocardiography is a new noninvasive ultrasound imaging technique that allows for an objective and quantitative evaluation of global and regional myocardial function independently from the angle of insonation and from cardiac translational movements.Aim of the study : to assess the value of longitudinal strain versus coronary angiography in detection of coronary artery disease Patients and method : A cross sectional study was conducted in Ibn - Albitar hospital during the period between March 2015 and March 2016 and a sample of 72 patients was selected with positive coronary angiography. Results : The mean age of patients was 56.4 ± 10.1 years; furthermore, 73.6% of the patients aged more than 50 years. About half of the patients, (51.4%) were smokers, (73.6%) were diabetic, (33.3%) were hypertensive and (58.3%) had hyperlipidemia. the findings of 2D LV Longitudinal strain - speckle tracking, positive LADA (left anterior descending artery) stenosis was reported in (86.1%), the CX artery stenosis reported in (76.4%) and the RCA stenosis was found in (84.7%) of the patients. for the stenosis in LADA, the current study showed that the longitudinal strain was a good predictor with a sensitivity of (93.8%), specificity (75%) and accuracy (91.7%) compared with coronary angiography, with good performance of the test between tests, good predictive value and accuracy of the test.The longitudinal strain showed that there was a good performance in detection of stenosis in CXA with high sensitivity, specificity and accuracy. The performance and validity of 2D LV longitudinal strain in detection of RCA stenosis in comparison with angiography, it had a sensitivity of (93.5%), specificity of (70.0%) and accuracy of (90.3%).Conclusion : The current study revealed that the Speckle - tracking echocardiography technique has a good performance and validity in detection of coronary artery stenosis with very good agreement with angiography.

المستخلص: Background : Elastic properties of the aorta affect the left ventricular function and epicardial arteries blood flow. Thats why several parameters are used to assess those properties in order to predict the likelihood of atherosclerotic coronary artery disease. Those parameters include aortic strain, aortic distensibility and early diastolic velocity of the anterior aortic wall.Objectives : Testing the value of aortic propagation velocity as a parameter of aortic stiffness in predicting coronary artery disease. The strength of this parameter in predicting the number of affected coronary arteries is also assessed.st of August 2015 to the 1 st Study population and methodology : From the 1 of July 2016, and after applying the inclusion and exclusion criteria, 120 patients were included in this comparative multi - center study. They were assessed for demographic criteria and risk factor profiles. Trans thoracic echocardiographic examination was done, all the needed measurements were obtained as well as measuring the carotid intima media thickness by Doppler, then the results of their coronary angiography were revised, 60 patients were included in the coronary artery disease group and another 60 in the non - coronary artery disease group.Results : Aortic propagation velocity was found to be related to the aortic distensibility, strain, early diastolic anterior aortic wall velocity and the overall carotid intima media thickness to a statistically significant level (r=+0.481, p<0.001; r=+0.548, p<0.001; r=+0.595, p<0.001; r= - 0.361, p<o.oo1 respectively). It was found that aortic propagation velocity predicts coronary artery disease (p<0.001) and correlates with the number of affected coronary arteries (r= - 0.711, p<0.001).Conclusion : Aortic propagation velocity is an easily applied echocardiographic parameter of aortic stiffness that can predict coronary artery disease caused by vascular atherosclerosis in a non - invasive way. It also correlates with the number of the affected coronary arteries.

المستخلص: Hypertension is one of the most common diseases in the world and can cause many structural and functional cardiac abnormalities. One of these changes is left ventricular systolic dysfunction which may not be detected by conventional echocardiographic parameters and need to use a new modality of two dimensional speckle tracking strain for early detection and improvement of prognosis Objectives : Assessment of left ventricle systolic function in hypertensive patients with normal ejection fraction using two dimensional speckle - tracking stain and its role as early predictor of subclinical dysfunction Patients and methods : This was a comparative observational study of two groups of individuals : (100)hypertensive patients and (50) normotensive subjects were enrolled in the study which take place at Ibn Al - Bittar Teaching Hospital from September 2015 to August 2016. Both the conventional echocardiographic parameters (ejection fraction, left ventricular mass and relative wall thickness, diastolic function and mitral annular plane systolic excursion) and speckle tacking longitudinal strain done for the patients. Results : Hypertensive patients with mean age (53.6 ± 5.37), males were (56%) and females were (44%),two dimensional speckle strain showed no significant differences between normotensive ( - 21.1 ± 2.5%) and hypertensive ( - 19.2 ± 3.9%) groups.Applying Cut off value of ( - 17.5%), it was found that 21% of hypertensive patient were present with undetected left ventricular systolic dysfunction even with preserved ejection fraction Global longitudinal strain was reduced significantly in those with concentric left ventricle hypertrophy ( - 18.2 ± 3.5%, p value=0.02),elevated in left ventricular end diastolic pressure ( - 14.8 ± 1.6% , p - value= 0.002) and reduced mitral annular plane systolic excursion ( - 14.8 ± 1.6%, p - value=0.008) Conclusion : Speckle tracking stain is a useful tool in the early detection of subtle left ventricular systolic dysfunction in a group of hypertensive patients with preserved ejection fraction and in whom more aggressive interventions could have a significant impact on prognosis.

المستخلص: Background : Mitral Stenosis refers to narrowing of the mitral valve orifice, resulting in impairment of filling of the left ventricle in diastole. It is usually caused by rheumatic heart disease. Proximal isovelocity surface area measurement, also known as the “flow convergence” method, can be used in Transthoracic Echocardiography to estimate the area of an orifice through which blood flows.Objectives : To compare simple PISA equation, created by combined fixing the angle to 1000 and the Val to 33 cm/s, with mitral valve area measured by pressure half time and planimetry which was taken as reference method.Patients and Methods : A cross sectional prospective study was conducted in multi teaching centers (Baghdad teaching hospital, Ibin AL Nafees hospital, Ibn AL Bitar hospital and Ghazi AL Harriry teaching hospital) from the June 2015 to the June 2016. 104 patients were enrolled in this study, 41 were excluded from the study (patients with mild mitral stenosis, with aortic regurgitation, mitral regurgitation and those with poor window were excluded from the study). Transthoracic echocardiographic examination include para sternal long axis, apical four chamber and parasternal short axis view were used to analyze parameters were selected by M - mode, 2D, and pulse doppler Results : There were 63 patients enrolled in this study with a mean age of 45.4 ± 7.1years, (23.8%) of them within the age group 30 - 39 years and the remaining (76.2%) were > 40 years. Female patients were the dominant represented 73.0% while male were 7.0% of the studied group (female : male ratio was 3 : 1); (61.9%) were in sinus rhythm and (38.1%) in atrial fibrillation. 58.7% of the patients are with Wilkin's score less than8, the mean mitral valve area according to planimetry method was (1.14 ± 0.32) cm2 and it was (1.12 ± 0.28) cm2 by PISA while the mean mitral valve area by pressure half time method was (1.19 ± 0.30) cm2. The agreement between PISA and planimetry revealed that PISA had good agreement with planimetry in diagnosis of mitral stenosis, (kappa= 0.835, P< 0.001). On the other hand, there was a fair significant agreement between pressure half time and planimetry.Conclusions : PISA method can effectively predict mitral valve area and severity of mitral stenosis by the equation; mitral valve area = 115 _ r2/Vmax, Provided that aliasing velocity is fixed at 33 cm/s, with the advantage of easy calculation over other methods used to evaluate mitral valve area by Trans thoracic Echocardiography.
