The Impact

The cardiorenal syndrome (CRS) is a complex clinical syndrome in which dysfunction of either the heart or the kidneys affects the functioning of the other organ system. Many therapies used in heart failure have further detrimental effects on renal function. Cardiac resynchronization therapy (CRT) is a relatively new form of device therapy that reduces morbidity and mortality in patients with heart failure. This review will discuss the effects of CRT on renal function in patients with CRS, the impact of baseline renal function on response to CRT, and potential risks associated with CRT in this unique population.

Abstract Background Randomized control trials comparing the effectiveness of cardiac resynchronization therapy devices, with (CRT-D) or without (CRT-P) a defibrillator, are scarce in heart failure patients. Patients with nonischemic dilated cardiomyopathy (NICM) may be at lower risk for ventricular arrhythmias compared with those with ischemic cardiomyopathy. In addition, NICM has been identified as a predictor of positive response to CRT. The aim of this study was to investigate the impact of an additional implantable cardioverter-defibrillator over CRT in Korean patients with NICM. Methods During the period from January 1, 2008 to December 31, 2017, 533 NICM patients (mean age, 65.7±12.2 years, male 53.6%) with newly-implanted CRT-P (n=71) or CRT-D (n=462) who were aged 19 years or older were identified by 50-percents random sampling from the Korean National Health Insurance Service database. Results Compared with patients receiving CRT-P, those receiving CRT-D were younger (65.3±12.3 vs. 68.3±11.6 years, p=0.038), more likely to be male (56.1% vs. 38.0%, p=0.005), and have an admission history of congestive heart failure (93.9% vs. 87.3%, p=0.041). Over the mean follow-up period of 21 months,114 cases in the CRT-D group and 24 cases in the CRT-P group died, with annualized mortality rates of 14.9 and 17.2 per 100 person-years, respectively. Kaplan-Meier estimates of event-free survival showed that there was no difference in mortality between CRT-D and CRT-P groups (p=0.343). In multivariate analysis, factors associated with mortality were chronic kidney disease, atrial fibrillation, and older age. With regard to death or heart failure hospitalization, heart failure death, and non-cardiac death, there were no difference between the two groups. Conclusions Among Asian patients with NICM with indications for CRT, death, death or heart failure hospitalization, heart failure death, and non-cardiac death were not different between CRT-D and CRT-P groups.

The Impact

Background: It’s well known that cardiac resynchronization therapy (CRT) is effective to reduce heart failure hospitalization. However, the impact of response to CRT on ventricular arrhythmic events is not well established. Methods: We investigated 216 pts received CRT in two institutions (age 69.3+/−10.8 years, NYHA class 3.1+/−0.5, LVEF 25.8+/−7.4%, LVEDD 62.1+/−8.3mm, pre QRS duration 158+/−32ms, AF 19.4%, ischemic heart disease 33.3%, CRT-D 51.3%) and divided into two groups, Responders (n=145, 67.1%) and Non-responders (n=71, 32.9%). CRT responder was defined as improvement of LVEF > or =5%, or reduction of LVEDD > or = 5mm at 3–6 month echo data. Long-term ventricular arrhythmic events (ventricular tachycardia: VT, ventricular fibrillation: VF and sudden cardiac death: SCD) were obtained. Kaplan-Meier curve were draw and Long-Rank test was used to compare event rates of two groups. Results: Mean follow up periods was 19.3 +/−12.7 months. Event free survival rates from ventricular arrhythmic events (VT, VF and SCD) were all significantly higher in Responders compared to Non-responders (VT: 89.2% vs. 77.8% at 2 year, Log-rank p=0.031, VF: 99.2% vs. 89.9% at 2 year, Log-rank p=0.0031, SCD: 98.6% vs. 89.2% at 2 year, Log-rank p=0.0038) and event free survival rate from combined VT, VF and SCD was also significantly higher in Responders (87.8% vs. 76.5% at 2 year, Log-rank p=0.0013). Conclusion: Response to CRT seems to reduce not only heart failure events, but also ventricular arrhythmic events. Figure: Adverse events in new onset AF vs no AF
