Predicting Survival Beyond 5 Years On Continuous-Flow Left Ventricular Assist Device (LVAD): A Landmark Analysis From The STELLAR Registry
- bicenter observational landmark analysis
- large
Authors' conclusion
Among patients who have already survived five years on continuous-flow LVAD support, subsequent mortality was associated with routinely available markers of physiological and end-organ reserve. These findings characterize risk specifically in prevalent long-term LVAD recipients and warrant external validation.
Study context
- Population
- Patients who survived at least five years on continuous-flow LVAD support (HeartMate II, HeartWare (HVAD), HeartMate 3)patients surviving ≥5 years on LVAD support, 189 had complete data for multivariable analysis
- Participants
- 201 patients
- Exposure
- Clinical, laboratory, echocardiographic and hemodynamic parameters at the five-year time point as predictors of mortality from the five-year landmark (Cox proportional hazards regression)
