PG - 214-219 LID - 10.1097/MAT.0000000000001447 [doi] AB - The peripheral vascular effects of continuous-flow left ventricular assist device (CF-LVAD) implantation are still unclear. The aim of the current study was to determine peripheral vascular function before and after implantation of CF-LVAD in patients with end-stage heart failure (HF), and to compare this data to age- and sex-matched chronic heart failure with reduced ejection fraction (HFrEF) patients. Forty-three consecutive end-stage HF patients (New York Heart Association [NYHA] class III/IV; three women and 40 men; mean age 53 +/- 11 years) who planned to receive CF-LVAD implantation comprised the LVAD patient population, and their clinical characteristics, preoperative and third postoperative month peripheral vascular function assessment data including flow-mediated dilation (FMD) and pulsatility index (PI) assessed by ultrasound Doppler in brachial artery were compared to age- and sex-matched chronic, stable HFrEF patients (NYHA class II; five women and 30 men; mean age 51 +/- 10 years). After CF-LVAD implantation, median FMD decreased from 5.4 to 3.7% (p < 0.001), and median PI decreased from 6.9 to 1.4 (p < 0.001). In patients with end-stage HF before CF-LVAD implantation, FMD and PI were significantly lower compared to the chronic HFrEF patients (FMD: 5.4% +/- 0.9% vs. 7.6% +/- 1.1%; p < 0.001, respectively) and (PI: 6.9 +/- 1.3 vs. 7.4 +/- 1.2; p = 0.023, respectively). The current study revealed impaired peripheral vascular function in the end-stage HF patients compared to stable HFrEF patients, and documented the deterioration of peripheral vascular function after CF-LVAD implantation. These results suggest that impaired peripheral vascular function in the CF-LVAD patients compared to preoperative assessment is a consequence of the nonpulsatile blood flow due to the continuous-flow mechanical support.
