TL;DR: Heart failure is a syndrome characterized by high mortality, frequent hospitalization, reduced quality of life, and a complex therapeutic regimen that makes HF an ideal candidate for practice guidelines.

TL;DR: Remote follow-up of device data is associated with excellent survival, but arrhythmias that result in device therapy in this population are associated with a higher mortality risk compared with patients who do not require shock therapy.
Abstract: Background—Outcome data for patients receiving implantable cardioverter-defibrillator (ICD) and cardiac resynchronization therapy–defibrillator (CRT-D) devices treated outside of clinical trials are lacking. No clinical trial has evaluated mortality after device implantation or after shock therapy in large numbers of patients with implanted devices that regularly transmit device data over a network. Methods and Results—Survival status in patients implanted with ICD and CRT devices across the United States from a single manufacturer was assessed. Outcomes were compared between patients followed in device clinic settings and those who regularly transmit remote data collected from the device an average of 4 times monthly. Shock delivery and electrogram analysis could be ascertained from patients followed on the network, enabling survival after ICD shock to be evaluated. One- and 5-year survival rates in 185 778 patients after ICD implantation were 92% and 68% and were 88% and 54% for CRT-D device recipients....

TL;DR: In a multisite clinical trial setting, it is shown that the achieved test-retest reproducibility for peak Vo2 can be acceptable, as evidenced by a CV at 5.9%.

TL;DR: It is noted that if one considers the percent of deaths attributable to heart failure among the patients who died in each arm, this percentage would be higher in the implantable cardioverter-defibrillator (ICD) arm than in the others simply because the total number of deaths in the ICD arm is reduced compared with the other arms.
Abstract: We appreciate the useful insights contributed by the authors of the Letter to the Editor. Although the published article from the Sudden Cardiac Death in Heart Failure Trial (SCD-HeFT) investigators1 did not view the data from the perspective of evaluating the different modes of death given that a death occurred (as did the authors of the letter), we appreciate that this approach provides a different perspective of the data. We simply note that if one considers the percent of deaths attributable to heart failure among the patients who died in each arm, this percentage would be higher in the implantable cardioverter-defibrillator (ICD) arm (even if the numbers of heart failure deaths in each arm were identical) simply because the total number of deaths in the ICD arm is reduced compared with the other arms. That is, the …
