ABSTRACT
Introduction: Left ventricular (LV) diastolic dysfunction is common on preoperative screening among patients undergoing surgery. There is no simple screening test at present to suspect LV diastolic dysfunction. This study was aimed to test the hypothesis, whether elastic recoil signal (ERS) on tissue Doppler imaging of mitral annulus (MA TDI) can be used as a qualitative test to differentiate patients from normal LV diastolic function versus patients with LV diastolic dysfunction. Methods: This was a prospective cross-sectional observational study of patients admitted for elective surgeries. Normal diastolic function and categorization of LV diastolic dysfunction into severity grades I, II, or III were performed as per the American Society of Echocardiography/ European Associationof Cardio Vascular Imaging (ASE/EACVI) recommendations for LV diastolic dysfunction. Results: There were 41 (61%) patients with normal LV diastolic function and 26 (39%) patients with various grades of LV diastolic dysfunction. In 38 out of 41 patients with normal LV diastolic function, the characteristic ERS was identified. The ERS was absent in all the patients with any grade of LV diastolic dysfunction. Consistency of identification of ERS on echocardiography was tested with a good interobserver variability coefficient of 0.94 (P-value <0.001). The presence of ERS demonstrated an excellent differentiation to rule out any LV diastolic dysfunction with an area under the receiver operating characteristics curve (AUROC) of 0.96 (CI 0.88�99; P value <0.001). Conclusions: To conclude, in a mixed surgical population, the anesthetist could successfully assess LV diastolic dysfunction in the preoperative period and the characteristic ERS on MA TDI signal can be used as a qualitative test to differentiate patients from normal LV diastolic function versus patients with LV diastolic dysfunction using the transthoracic echocardiography (TTE).
ABSTRACT
Background: Chronic kidney disease is a major public health problem worldwide with continuously increasing incidence and prevalence. Diabetes and hypertension are the leading causes of chronic kidney disease worldwide, whereas hypertension is a cause as well as effect of chronic kidney disease. Objectives: To evaluate and analyze the echocardiographic changes in the end stage renal disease patients on maintenance haemodialysis by the help of 2-D echocardiography. Materials and methods: End stage renal disease (ESRD) patients who were on maintenance haemodialysis for at least 3 months, in MG hospital were included in the study. We performed 2- Dechocardiography in 50 ESRD patients during inter-dialytic period. Patients with clinical evidence of coronary artery disease, previous history of hypertension, valvular heart disease, congenital heart disease and pericardial effusion were excluded from this study. Results: out of 50 chronic kidney disease patients, echocardiography revealed LVH in 29 (58%) patients, LVDD in 25(50%) patients, pericardial effusion in 10 (20%) patients, pulmonary hypertension in 23(46%) patients, dilated left atrium in 14(28%) patients, dilated left ventricle in 4 (8%) patients and regional wall motion abnormalities in 3 (6%) patients. Hypertension was present in Saxena N, Dhamija JP, Saxena S. Role of 2-D echocardiography in detecting cardiovascular abnormalities in chronic kidney disease patients: Case series of 50 chronic kidney disease patients. IAIM, 2017; 4(1): 122-126. Page 123 46 (92%) out of 50 CKD patients out of which LVH was in 29 patients. Severe Anaemia was present in 10 (20%) patients. Conclusion: LV diastolic dysfunction and left ventricular hypertrophy were the most common and significant echocardiographic findings among 50 CKD patients. There was statistically significant correlation between anaemia and the presence of left ventricular hypertrophy and positive correlation between presence of hypertension and left ventricular hypertrophy.
