  • Normally distributed variables are displayed as mean±SD. Non-normally distributed variables are presented as median (IQR). Proportions are displayed as n (%).

  • *P for trend was calculated using linear regression models for normally distributed variables and Cuzick’s non-parametric test for trend for non-normally distributed variables.

  • A, late mitral inflow velocity; BMI, body mass index; COPD, chronic obstructive pulmonary disease; DBP, diastolic blood pressure; e', mitral annular early diastolic velocity; E, early mitral inflow velocity; INR, international normalised ratio; LV, left ventricular; MI, myocardial infarction; SBP, systolic blood pressure; TR, tricuspid regurgitation.
