Figure 1. Cohort and timeline summary for RHF determination following LVAD implantation.

Figure 1

Individuals were included in the overall cohort if they had at least 1 follow‐up at the time of the 1‐month follow‐up assessment or later. The INTERMACS protocol targeted follow‐up visits at 1 week, and 1, 3, 6, and 12 months, although actual follow‐up times necessarily varied. For assessing RHF at the 1‐month and 3‐month follow‐ups, the time periods of 0.75 to 1.5 months postimplantation, and 2.5 to 3.5 months postimplantation were used, respectively (represented by widths of the columns). The times with patient data available are represented by the vertical gray dashes on the x axis. INTERMACS indicates Interagency Registry for Mechanically Assisted Circulatory Support; LVAD, left ventricular assist device; and RHF, right heart failure.
