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

ABSTRACT:

Background

Heart failure (HF) is a rapidly growing public health issue in super aging societies, such as Japan. Right HF is common in older patients. Therefore, the present study investigated the relationship between right ventricular diastolic function and poor clinical outcomes in patients with HF.

Methods

We retrospectively enrolled 387 Japanese HF patients. All data were obtained from our echocardiographic and jugular venous pulse (JVP) databases and medical records. A less-distensible right ventricle (RV) was identified by a deeper 'Y' descent than 'X' descent in the JVP waveform. We defined cardiac events of HF as follows: sudden death, death from HF, emergent infusion of loop diuretics, or hospitalization for deterioration of HF. Comparisons between patients with and
