Abstract Funding Acknowledgements ÖNB Jubiläumsfondsprojekt Nr. 15974, ISR grant by Boston Scientific, St. Paul, MN, USA Background Central sleep apnea (CSA) in pacing induced cardiomyopathy (PICM) is poorly studied. Specifically, it is unknown whether upgrading from right ventricular pacing (RVP) to cardiac resynchronisation therapy (CRT) improves CSA. Methods Fifty-three patients with impaired left ventricular ejection fraction, frequent right ventricular pacing due to high-grade atrioventricular block and heart failure symptoms despite optimal medical therapy underwent upgrading to CRT. Within one month after left ventricular lead implantation (but still not activated), sleep apnea was assessed in all participants by single-night polysomnography (PSG). Nineteen patients with moderate or severe CSA defined by an apnea hypopnea index (AHI) > 15 events per hour were re-scheduled for a follow up PSG 3-5 months after initiation of cardiac resynchronization therapy. Of this cohort, thirteen patients with stable mild heart failure agreed to be randomized to CRT versus RVP in a cross-over design. Results CSA (AHI > 5 events per hour) was diagnosed in 26 (49.1%), OSA in 16 (30.2%) patients suffering from PICM . Eleven (20.8%) patients did not have any form of sleep apnea. Moderate to severe CSA (AHI > 15 events per hour) was significantly improved (without specific CPAP therapy) by 102 (96-172) days of CRT: AHI decreased from 39.4 events per hour at baseline to 21.6 by CRT (p < 0.001). Furthermore, CRT led to a substantial decrease in left ventricular endsystolic volumes: baseline 141 ml (103-155), significant improvement under CRT (102 ml, 65-138; p < 0.001), whereas no effect with ongoing RV-pacing (147 ml, 130-161; p = 0.865). Preexistent CSA did not affect the structural response of CRT (56.5% in patients with CSA, 62.5% of patients with obstructive sleep apnea and 54.5% in patients without sleep apnea; p = 0.901) and had no impact on major adverse cardiac events (p = 0.412) and/or survival (p = 0.623) during long-term follow-up. Conclusions CSA is highly prevalent in patients with PICM and is significantly improved by upgrading to CRT. Preexistent CSA does not hamper structural improvement and long-term outcome after upgrading to CRT. Thus, CSA seems to occur as a consequence of PICM, rather than as a pathophysiological mediator.

Rv Function

Abstract Background Right ventricular (RV) dysfunction is present in a substantial proportion of candidates for cardiac resynchronization therapy (CRT) but its prognostic implication has not been fully determined. We investigated the association of different echocardiographic indices of RV function and survival in patients with heart failure (HF) and conduction delays. Methods A total of 122 HF patients with bundle branch blocks (BBB), not treated with device therapy, were included in this retrospective observational study. RV function was assessed by measuring the tricuspid annular plane systolic excursion (TAPSE) and RV free wall longitudinal strain (RVFWSL). Patients were followed for cardiac mortality during a median period of 33 months. Results Both TAPSE ≤ 18 mm and RVFWSL≥-25% were associated with unfavorable long-term survival (log rank p < 0.05 for both, Figure A and B). Importantly, in patients with normal TAPSE, RVFWSL remained predictive of long-term outcome (HR 1.15, 95% CI 1.003-1.327; p = 0.045). In the multivariate regression analysis, only NYHA class (HR 2.21, 95%CI (1.122 – 4.357; p = 0.022) and RVFWSL (HR 1.11, 95%CI 1.029 – 1.204; p = 0.008) were independently associated with cardiac mortality. Significant differences among segmental RVFWLS values were observed, including a basal-to-apical gradient with the highest strain values in the base and the lowest in the apex (Figure C). Conclusions RV dysfunction is associated with unfavorable survival in HF patients with BBB. RVFWSL appears to be stronger predictor of mortality than TAPSE. Different segments of the RV may contribute differently to RV dysfunction in patients with conduction delays. Abstract 1026 Figure.

Aim The Program to Access and Review Trending iNformation and Evaluate coRrelation to Symptoms in patients with Heart Failure (PARTNERS HF) trial elaborated a multiparametric model for prediction of acute decompensation in advanced heart failure patients, based on periodical in office data download from cardiac resynchronisation devices. In this study, we evaluated the ability of the PARTNERS HF criteria to detect initial decompensation in a population of moderate heart failure patients under remote monitoring. Methods We retrospectively applied the PARTNERS HF criteria to 1860 transmissions from 104 patients (median follow up 21 months; range 1–67 months), who were enrolled in our programme of telemedicine after cardiac resynchronisation therapy. We tested the ability of a score based on these criteria to predict any acute clinical decompensation occurring in the 15 days following a transmission. Results In 441 cases, acute heart failure was diagnosed after the index transmission. The area under the curve (AUC) of the score for the diagnosis of acute decompensation was 0.752 (confidence interval (CI) 95% 0.728–0.777). The best score cut-off was consistent with the results of PARTNERS HF: with a score ≥2, sensitivity was 75% and specificity 68%. The odds ratio for events was 6.24 (CI 95% 4.90–7.95; p < 0.001). Conclusions When retrospectively applied to remote monitoring transmissions and arranged in a score, PARTNERS HF criteria could identify HF patients who subsequently developed acute decompensation. These results warrant prospective studies applying PARTNERS HF criteria to remote monitoring.
