Impact of decreasing Wpeak/LVEDDrest and Wpeak alone on the risk of cardiovascular death. The hazard ratios (95% confidence intervals) were calculated using Cox regression and modelled with natural cubic splines with four knots (percentiles: 5th, 25th, 75th, 95th) and presented as unadjusted estimates (left panels) and adjusted for age and sex (right panels). Wpeak/LVEDDrest showed a substantial risk increase with low values both for adjusted and unadjusted estimates.
