echocardiographic test and the early detection of systolic failure in systemic sclerosis patients: strain and strain rate echocardiography

چکیده
objectives in this study, besides studying the rv function in ssc patients, attempts have been made to find a new possible noninvasive echocardiographic test for early diagnosis of systolic failure as a pah complication. methods 30 patients with at least a 2-year history of diffuse ssc confirmed by an expert rheumatologist were enrolled in this study. all the patients underwent transthoracic echocardiography by an echocardiologist. fractional area change (fac) of the right ventricle (rv), tricuspid annular plane systolic excursion (tapse), rv lateral wall strain and strain rate (base, mid, apex), rv-edd and rv pressure with respect to inferior vena cava (ivc) diameter as well as left ventricle’s ejection fraction (lvef) were evaluated. results the prevalence rate of pah was reported 36.6% in this study. there was no significant relationship between lvef and rv parameters. lvef was found to be significantly higher in women whereas rv strain turned out to be higher in men. besides, there was a significant relation between pulmonary arterial pressure (pap) and basal (p = 0.03), mid rv strain (p = 0.002), rv strain rate (p = 0.001) and rv diameter (p = 0.02). also, an inverse relation was observed between rv systolic (p = 0.01) and diastolic functions (p = 0.007) with pap. in addition, no significant relationship was found between lvef and body mass index (bmi) and rv parameters (p > 0.05). moreover, apical rv strain and lvef were found to be higher in males and females respectively. furthermore, a significant relationship was found between rv strain and age (p = 0.027). finally, the results did not show any relationship between rv systolic and diastolic functions and gender. conclusions this paper states the likely advantages of strain and strain rate echocardiography in identifying patients with more diffused and severe ssc and the need for further longitudinal studies based on the mentioned method for early diagnosis of myocardial impairment. background pulmonary arterial hypertension (pah) is a leading cause of death in systemic sclerosis (ssc) patients. early detection of systolic failure in ssc patients will facilitate early treatment and improve the survival rate of these patients.

right ventricular strain and strain rate in patients with systemic sclerosis without pulmonary hypertension
conclusions this study indicated that the rv systolic strain and strain rate can be used to detect early rv systolic dysfunction in ssc patients without pulmonary hypertension. these parameters may be useful for the provision of a more adequate management of ssc patients. results in the ssc patients, the rv strain (- 19 ± 10 vs. - 25 ± 4 %; p = 0.004) and the systolic strain rate (- 1.3 ± 0.5 v...

Evaluation of strain and strain rate parameters using two-dimensional speckle-tracking echocardiography in patients with coronary artery disease (Research Article)
The study aimed was to measure left ventricular (LV) strain using speckle tracking echocardiography (STE) for assessment of LV function. Eighty-two subjects (mean age 57±9 years) with suspected chest pain underwent two-dimensional (2D)-echocardiography before coronary angiography. Conventional echocardiographic parameters were used for the assessment of LV function. Longitudinal strain and its ...
