Abstract
Our study included 50 cases (35 as a patients group and 15 as a control group) collected from patients admitted or following up in the outpatient clinic of the Cardiology Department, Specialized Medical Hospital, Mansoura University between 2017-2018. Inclusion criteria of our patients included ischemic heart disease, valvular heart disease, long standing hypertension. Exclusion criteria in our study were patients with evident left ventricular systolic dysfunction (EF <59%), patients with chronic hepatic or renal diseases. History taking was done for all patients including personal, present, past history. For all patients clinical examination was done including general and local cardiac examination. ECG was done for all patients for detection of arrhythmia, left ventricular hypertrophy, strain, and presence or absence of myocardial ischemia or infarction. For all patients Transthoracic echocardiography was done including 2D, M mode, PWD, and CWD. The views done were parasternal long axis view, parasternal short axis view at different levels, apical 4 chamber view, and apical 5 chamber view. Diastolic wall stress, Apical systolic excursion were derived from M mode and left ventricular strain (longitudinal) was derived from tissue tracking. We found that presence of smoking for patients group shows high significance regarding to control group (0.001) and of the patients group 74.3% were hypertensive (0.001) and 28.6% were diabetic (0.02), while all cases of control group were non hypertensive and non diabetic. Of the patients group 54.3% had past history of coronary artery disease , 31.4% had long standing hypertension and 14.3% had valvular heart disease with high significance correlation between the patients group and the control group (<0.001). There was no significant correlation between the patients group and the control group regarding lower limb edema , congested neck veins, basal crepitations and wheezes. There was no significance correlation between both groups regarding pulse (0.2) . On the other hand there was significant correlation between both groups regarding SBP (0.01) and DBP (0.015) . There was no significance between both groups regarding ESD, EDD, EF, FS and PWD.
We concluded that Diastolic wall stress and apical systolic excursion measured by M mode can be applied efficiently for detection of subclinical left ventricualr systolic dysfunction as well as longitudinal strain that measured by tissue tracking method.
