European Sleep Apnea and Sudden CArdiac Death ProjEct (ESCAPE-SCD)
The objective of ESCAPE-SCD Study is assessment of the effect of sleep apnea on sudden cardiac death risk and cardiovascular outcomes in patients with ischemic cardiomyopathy. The ESCAPE - SCD Study will address following specific study questions:
- Is obstructive sleep apnea (OSA) and/or central sleep apnea (CSA) an independent risk factor of sudden cardiac death (SCD) in patients with ischemic cardiomyopathy (ICM) indicated for ICD/CRT-D implant based on current European Society of Cardiology (ESC) Guidelines for primary prevention of sudden cardiac death?
- Can treatment of predominant (>50%) obstructive sleep apnea by appropriate Positive Airway Pressure (PAP) therapy decrease risk of sudden cardiac arrhythmic death in ICM patients?
- Can treatment of predominant (>50%) obstructive sleep apnea by appropriate PAP therapy improve cardiovascular outcomes in ICM patients indicated for ICD/CRT-D implant?
- Does obstructive sleep apnea represent a novel factor that may improve risk stratification of sudden cardiac death and advance identification of those patients that will benefit from ICD/CRT-D therapy?

Detailed Description
Detailed Study Description
Purpose:
There is strong evidence that patients with ischemic cardiomyopathy have high cardiovascular mortality, including high risk of sudden cardiac death. Sleep apnea is frequently present in patients after myocardial infarction/with ischemic cardiomyopathy (approximately in 50% of patients).
Both central and obstructive sleep apnea are considered as independent risk factors of worsened prognosis in patients with heart failure with reduced ejection fraction (HFrEF). However, there is no evidence from randomized trials yet providing evidence that sleep apnea is an independent risk factor leading to an increase in cardiovascular mortality, including increased risk of sudden cardiac arrhythmic death in patients with ischemic cardiomyopathy. There are also no data from randomized trials assessing if treatment of sleep apnea by positive airway pressure therapy may improve cardiovascular outcomes in these patients, including reduced risk of sudden cardiac death.
Rationale:
ICD therapy decreases risk of sudden cardiac death in patients with HFrEF, including patients with ICM with left ventricular ejection fraction of <35%. Current ESC Guidelines for implantable cardioverter defibrillator (ICD) therapy for primary prevention of sudden cardiac death in patients with ischemic cardiomyopathy have high sensitivity and high positive predictive value. A limitation of current guidelines is low specificity and low negative predictive value. In real clinical practice, it means that less than 1/3 of patients with heart failure with reduced ejection fraction who get the ICD device for an indication of primary prevention of sudden cardiac death will receive appropriate ICD discharge. The remaining 2/3 of patients have no benefit from ICD implantation, and are exposed to risks of complications resulting from ICD implant, such as inappropriate ICD discharges, lead dislocation, or even life-threatening complications such as infectious endocarditis or myocardial perforation.
Therefore, improvements of stratification criteria allowing better identification of those patients with ICM that will have real benefit from ICD therapy, and improvement of long-term outcomes and cost-benefit of ICD therapy, represent one of the major challenges of modern cardiology.
Previous studies show that sleep apnea increases the risk of sudden cardiac death in the population. In other words, sleep apnea represents a treatable condition which is also a potential risk factor of sudden cardiac death. Some previously non-randomized studies showed that in patients with HFrEF, both obstructive and central sleep apnea may increase risk of sudden cardiac arrhythmic death. Contrary to these observations, recently released preliminary data from the SERVE-HF trial indicate that in patients with HFrEF, treatment of central sleep apnea by adaptive servo-ventilation therapy increases cardiovascular mortality, and responsible mechanisms might include increased risk of sudden cardiac death.
There are several pathophysiological mechanisms by which both obstructive and central sleep apnea may increase risk of sudden cardiac arrhythmic death in ICM patients. Considering the high prevalence of sleep disordered breathing in patients with ICM, sleep apnea represents a modifiable risk factor, where proper treatment may decrease risk of sudden cardiac death and/or improve cardiovascular outcomes in ICM patients. However, randomized studies specifically addressing the role of sleep apnea in risk of sudden cardiac arrhythmic death in ICM patients are needed to clarify the existing controversy and provide information highly needed for routine clinical practice.
Objective
The ESCAPE - SCD Study will address following specific study questions:
- Is obstructive sleep apnea and/or central sleep apnea an independent risk factor of sudden cardiac death (SCD) in patients with ICM indicated for ICD/CRT-D implant based on current ESC Guidelines for primary prevention of sudden cardiac death?
- Can treatment of predominant (>50%) obstructive sleep apnea by appropriate Positive Airway Pressure (PAP) therapy decrease risk of sudden cardiac arrhythmic death in ICM patients?
- Can treatment of predominant (>50%) obstructive sleep apnea by appropriate PAP therapy improve cardiovascular outcomes in ICM patients indicated for ICD/CRT-D implant?
- Does obstructive sleep apnea represent a novel factor that may improve risk stratification of sudden cardiac death and advance identification of those patients that will benefit from ICD/CRT-D therapy?
Study Design:
Prospective, randomized, international multi-centric study.
Study Population:
900 patients with ICM indicated for ICD/CRT-D implant based on 2012 and 2013 ESC Guidelines for primary prevention of sudden cardiac death (see Section: "References") will be enrolled in this study. A sleep study will be performed in each of the subjects and based on results patients will be divided to 4 Groups.
• No or Mild Sleep Apnea Group (Group 1): Patients with no or mild sleep apnea will continue with standard therapy (ICD/CRT-D implant + maximal medical therapy).
Patients with moderate and severe predominant obstructive sleep apnea (AHI >15) will be randomized in 1:1 ratio to
- Obstructive Sleep Apnea - Control Group (Group 2) - patients with predominant obstructive sleep apnea that will receive standard therapy (ICD/CRT-D implant + maximal medical therapy), but no PAP therapy for sleep apnea treatment and to
- Obstructive Sleep Apnea - Active Group (Group 3) - patients with predominant obstructive sleep apnea that will receive standard therapy (ICD/CRT-D implant + maximal medical therapy), plus, as intervention, sleep apnea treatment by using PAP therapy.
- Central Sleep Apnea Group (Group 4) - patients with predominant central sleep apnea that will receive standard therapy (ICD/CRT-D implant + maximal medical therapy). Because the SERVE-HF Trial demonstrated a negative effect of predominantly central sleep apnea treatment on cardiovascular mortality in patients with HFrEF by using adaptive servo-ventilation therapy, patients in Group 4 will not receive any PAP therapy for treatment of sleep disordered breathing and will be followed.
Distribution of Patient Population among Study Group:
Based on data derived from our pilot study, approximately 60% of patients with ischemic cardiomyopathy indicated for ICD/CRT-D implant for primary prevention of sudden cardiac death have undiagnosed moderate or severe sleep apnea. Therefore, we expect the following distribution of patients among patients' groups: Group 1: n=400 patients; Group 2: n=200 patients; Group 3: n=200, Group 4: n=100 patients.
Primary and secondary goals:
Primary goal:
- Assessment of sleep apnea and its treatment on risk of sudden cardiac arrhythmic death by assessing the number of appropriate ICD/CRT-D discharges for each of the groups
Secondary goals:
- Assessment of the effect of sleep apnea and OSA treatment on cardiovascular mortality and morbidity by assessing MACE (Major Adverse Cardiovascular Events)
- Assessment of incidence of complications resulting from ICD/CRT-D therapy among study groups
- Assessment of sleep apnea as a novel factor that may improve risk stratification of sudden cardiac death and advance identification of those patients that will benefit from ICD/CRT-D therapy.

Summary:
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.
