Why the study?
Do echocardiographic parameters (global longitudinal strain, deceleration time) predict 1-month rehospitalization and mortality in patients with dilated cardiomyopathy?
Do echocardiographic parameters (global longitudinal strain, deceleration time) predict 1-month rehospitalization and mortality in patients with dilated cardiomyopathy?
In patients with dilated cardiomyopathy, deceleration time (DT=100 ms), but not global longitudinal strain, predicts 1-month rehospitalization, which is associated with significantly higher mortality.
longitudinal strain does not seem to be associated with 1 month rehospitalization inspite of the fact that patients with DCM have got very low global longitudinal strain value as compared to normal population.Mortality rate in patients who were rehospitalized within 30 days is 63.64% (7 patients) and mortality rate among patients who were not rehospitalized within 30 days is 3.44% (2 patients ) [P?0.001].No other parameters were associated with 1 month rehospitalization or morlality among DCM patients.Conlusions: Global longitudinal strain was not associated with 1 month rehospitalization in patients having dilated cardiomyopathy in our study.As we found DT¼100 ms predicts 1 month rehospitalization and the mortality rate in this group of patients is significantly higher, so DT¼100ms maybe related to survival and having prognostic importance.Longitudinal strain in DCM
