This would be the very first randomized study assessing the effect of predominantly obstructive sleep apnea treatment on risk of sudden cardiac death and cardiovascular outcomes in patients with ischemic cardiomyopathy. The study will also address important questions related to improvement of selection of patients that may benefit from ICD/CRT-D therapy. We have solid evidence from our pilot data that addition of sleep disordered breathing screening and treatment may improve the selection of patients with ischemic cardiomyopathy that can benefit from ICD therapy, including improvement their long-term outcomes. Use of technologies for telemonitoring of efficiency of sleep disordered breathing treatment and occurrence of cardiac arrhythmias will increase the scientific strength of the study and will explore the benefit of use of telemonitoring technologies in daily clinical practice.
