Cardiac resynchronization therapy in inotrope‐dependent heart failure: a meta‐analysis

Aims: The viability of cardiac resynchronization therapy (CRT) in inotrope‐dependent heart failure (HF) has been a matter of debate. Methods and results: We searched Medline, EMBASE, Scopus, and the Cochrane Library until 31 December 2022. Studies were included if (i) HF patients required inotropic...

description Aims: The viability of cardiac resynchronization therapy (CRT) in inotrope‐dependent heart failure (HF) has been a matter of debate. Methods and results: We searched Medline, EMBASE, Scopus, and the Cochrane Library until 31 December 2022. Studies were included if (i) HF patients required inotropic support at CRT implantation; (ii) patients were ≥18 years old; and (iii) they provided a clear definition of ‘inotrope dependence’ or ‘inability to wean’. A meta‐analysis was performed in R (Version 3.5.1). Nineteen studies comprising 386 inotrope‐dependent HF patients who received CRT (mean age 64.4 years, 76.9% male) were included. A large majority survived until discharge at 91.1% [95% confidence interval (CI): 81.2% to 97.6%], 89.3% were weaned off inotropes (95% CI: 77.6% to 97.0%), and mean discharge time post‐CRT was 7.8 days (95% CI: 3.9 to 11.7). After 1 year of follow‐up, 69.7% survived (95% CI: 58.4% to 79.8%). During follow‐up, the mean number of HF hospitalizations was reduced by 1.87 (95% CI: 1.04 to 2.70, P < 0.00001). Post‐CRT mean QRS duration was reduced by 29.0 ms (95% CI: −41.3 to 16.7, P < 0.00001), and mean left ventricular ejection fraction increased by 4.8% (95% CI: 3.1% to 6.6%, P < 0.00001). The mean New York Heart Association (NYHA) class post‐CRT was 2.7 (95% CI: 2.5 to 3.0), with a pronounced reduction of individuals in NYHA IV (risk ratio = 0.27, 95% CI: 0.18 to 0.41, P < 0.00001). On univariate analysis, there was a higher prevalence of males (85.7% vs. 40%), a history of left bundle branch block (71.4% vs. 30%), and more pronounced left ventricular end‐diastolic dilation (274.3 ± 7.2 vs. 225.9 ± 6.1 mL). Conclusions: CRT appears to be a viable option for inotrope‐dependent HF, with some of these patients seeming more likely to respond.
