Abstract

Several studies have been reported using right ventricular (RV) strain as a method for evaluating RV function in patients with various cardiovascular diseases; however, the clinical relevance of RV strain in dilated cardiomyopathy (DCM) patients with sinus rhythm is unknown. The aim of this study was to investigate the relationship between RV strain and adverse events in DCM patients with sinus rhythm. We enrolled 143 DCM patients with sinus rhythm who had been first diagnosed, evaluated, and followed at Sanggye Paik Hospital between March 2013 and August 2017. We performed echocardiography and measured RV strain values using the apical four-chamber view. The mean age was 64.6 years. During the median follow-up period of 40.0 months, adverse cardiovascular events developed in 21 patients (14.7%). By Cox proportional hazards multivariate analysis, only RV free wall longitudinal strain (RV-FWLS) independently predicted the primary outcome. Receiver-operating characteristic curve analysis showed that the optimal RV-FWLS cut-off value to identify patients with an event was -16.5% (area under the curve = 0.703, P = 0.003). When we divided the subjects into two groups based on the RV-FWLS of -16.5%, patients with RV-FWLS <-16.5% show...Continue Reading

Cardiomyopathy

Cardiomyopathy is a disease of the heart muscle, that can lead to muscular or electrical dysfunction of the heart. It is often an irreversible disease that is associated with a poor prognosis. There are different causes and classifications of cardiomyopathies. Here are the latest discoveries pertaining to this disease.
