Current guidelines recommend ICD implantation in patients at high risk of sudden cardiac death with either ischemic or non-ischemic heart disease. However, implantation rate of cardiac implantable electrical devices (CIED), especially ICD, CRT and CRT-D, is lower than expected and do not reflect guideline indications.~Several factors may justify the differences in ICD implantation rates across Europe and the gap between daily clinical practice and guidelines: economic restrictions, poor guidelines awareness, especially among referring cardiologists and general practitioners, and different guidelines adherence. The impact of time-dependence of some indications to CIED implantation on the guidelines adherence is still unknown.~Objective of the present observational study will be the evaluation of the adherence to the scientific guidelines in patients with a time-dependent indication to ICD/CRT-D implantation admitted to an in-hospital cardiac rehabilitation program.~This is a prospective, multicenter, observational study performed in 6 cardiac rehabilitation facilities.
There are limited data on how the guideline indications for ICD implantation are applied in clinical practice across Europe. Moreover, the impact of time-dependence of some indications to implantation on the guidelines adherence is still unknown.~Objective of the present observational study is the evaluation of the adherence to the scientific guidelines in patients with a time-dependent indication to ICD/CRT-D implantation admitted to an in-hospital cardiac rehabilitation program.
