Right ventricular diastolic dysfunction worsens clinical outcomes in Japanese patients with heart failure

Multifaced risk factors and clinical impact of a deep Y descent in patients with heart failure irrespective of RV-PA coupling

“…Echocardiography was assessed as described in our previous study [10] . An echocardiographic examination (Vivid 7, General Electric Healthcare, Wauwatosa, WI, USA) was performed with reference to the guidelines [12] , [13] , [14] .…”

“…The jugular venous pulse (JVP) is non-invasive, easily examined in outpatient clinics, and reflects the characteristics of right ventricle during the diastolic phase [7] , [8] . We previously demonstrated that the presence of a deeper Y descent than the X descent in the JVP waveform suggested a decreased RV preload reserve, which has a negative impact on the clinical outcomes of HF [9] , [10] . The JVP waveform will provide insights into the relationship between RV-PA coupling and the RV preload reserve in patients with HF.…”
