What did studies of left ventricular assist device find?

6

Studies of left ventricular assist device measured 6 outcomes, among them frailty, cardiac function and survival.

Frailty

downin humans2

2 studies
  1. Left ventricular assist device is linked with lower frailty in humans (end-stage heart failure) (nearly half).

    “Physical frailty was reduced by nearly half at 12 months.”

  2. Left ventricular assist device is linked with lower frailty in 19 subjects with serial frailty measures (Fried frailty criteria 3.9 ± 0.9 to 2.8 ± 1.4 at 6 months, P = .003).

    “the average number of frailty criteria decreased from 3.9 ± 0.9 at baseline to 2.8 ± 1.4 at 6 months (P = .003)”

1 study
  1. Left ventricular assist device improves cardiac function during ex vivo heart perfusion.

    “LVAD mode was associated with significantly better cardiac function than the resting and working mode.”

1 study
  1. Left ventricular assist device is linked with better survival in humans (1-year survival: 80.6%, 5-year survival: 51.1%).

    “A focus on the subgroup of patients aged ≥65 years demonstrates excellent outcomes with respect to survival (1-year survival: 80.6%, 5-year survival: 51.1%)”

1 study
  1. Left ventricular assist device is linked with better quality of life in humans (post-LVAD) (40 to 75, P < 0.001).

    “quality of life improved from 40 (IQR: 15-60) to 75 (IQR: 60-90) (P < 0.001) after LVAD in all age groups.”
