Left ventricular assist device implantation improves glycaemic control: a systematic review and meta-analysis.

ABSTRACT: AIMS:Heart failure (HF) and diabetes mellitus (DM) often coexist and have bidirectional association. Advanced HF is associated with worsened glycaemic control. This meta-analysis investigated the effects of left ventricular assist device (LVAD) implantation on markers of DM control. METHODS AND RESULTS:We performed a systematic search of MEDLINE and Cochrane through October 2017 to identify studies evaluating advanced HF patients who had received an LVAD and reported markers of glycaemic control. The primary outcome was glycosylated haemoglobin A1c (HbA1c), and the secondary outcomes included fasting glucose, daily insulin requirements, and body mass index (BMI). Outcomes were pooled using a Hartung-Knapp random-effects model producing a mean difference (MD) and 95% confidence interval (CI). Thirteen studies, including 820 participants, were included. HbA1c was 1.23% lower following LVAD implantation (95% CI -1.49 to -0.98). Greater HbA1c reductions were seen with higher pre-LVAD values. Similarly, fasting plasma glucose (-24.4 mg/dL, 95% CI -33.4 to -15.5), daily insulin requirements (-18.8 units, 95% CI -28.8 to -8.7), and serum creatinine levels (MD -0.20, 95% CI -0.35 to -0.06) were significantly lower than pre-LVAD levels. We saw no difference in BMI (MD 0.09, 95% CI -1.24 to 1.42). CONCLUSIONS:LVAD implantation was associated with significant improvement in HbA1c, fasting plasma glucose, and daily insulin need in advanced HF patients.

Project description:Rationale & objectiveNearly half the patients with heart failure have chronic kidney disease. Implantation of a left ventricular assist device (LVAD) improves kidney function in some but not all patients, and lack of improvement is associated with worse outcomes. Preimplantation factors that predict change in kidney function after LVAD placement are not well described.Study designSingle-center observational study.Setting & participantsConsecutive patients undergoing LVAD implantation.Predictors48 diverse preimplantation variables including demographic, clinical, laboratory, hemodynamic, and echocardiographic variables.OutcomesThe primary outcome was change in estimated glomerular filtration rate (eGFR) at 1 month after implantation. Secondary outcomes included eGFR changes at 3, 6, and 12 months.Analytic approachUnivariable and multivariable linear regression.ResultsAmong 131 patients, average age was 60 ± 13 years, 83% were men, 47% had pre-existing chronic kidney disease, and mean preimplantation eGFR was 57 ± 23 mL/min/1.73 m2. At 1-month following LVAD implantation, eGFR improved in 98 (75%) patients. Variables associated with 1-month increases in eGFR were younger age, absence of diabetes mellitus (DM), use of inotropes, lower implantation eGFR, and higher implantation serum urea nitrogen, alanine aminotransferase, bilirubin, and creatinine levels. In multivariable models, younger age (β = 7.14 mL/min/1.73 m2 per SD; 95% CI, 3.17-11.10), lower eGFR (β = 7.72 mL/min/1.73 m2 per SD; 95% CI, 3.10-12.34), and absence of DM (β = 10.36 mL/min/1.73 m2; 95% CI, 2.99-17.74) were each independently associated with 1-month improvement in eGFR. Only younger age and lower eGFR were associated with improvements in eGFR at later months.LimitationsSingle-center study. Loss to follow-up from heart transplantation and death over duration of study.ConclusionsOnly younger age, lower eGFR, and absence of DM were associated with improvement in eGFR at 1 month. Thus, prediction of eGFR change at 1 month and beyond is limited by using preimplantation variables.
