简要总结
The purpose of the INSPIRE-ELR study is to characterize arrhythmias in post MI low EF (≤35%) patients in the acute phase (at discharge from hospital after index MI) and chronic phase (at 8-10 weeks after index MI) and to correlate with patients at high risk of all-cause mortality or sudden cardiac death (SCD) at 1 year.
详细描述
The study is a prospective, multi-center, interventional, non-randomized study enrolling post MI low left ventricular ejection fraction (LVEF ≤35%) patients prior to or at discharge from the hospital after index MI as defined in the inclusion criteria. Prior to initiating any study specific procedures, patients needs to provide his/her consent by signing and dating an informed consent form. Inclusion/Exclusion criteria will be evaluated and the patients' medical history and baseline information will be collected. Seven days ELR monitoring will be done at discharge and at chronic phase after index MI. At 6 and 9 months telephone follow-up will be done to evaluate the health status, if there will be no in-office visit planned. At 12 months there will be a scheduled in-office visit conducted to collect the health status. All the patients will be followed-up by telephone (health status) at study end (when the last patient completed the 12 month follow-up)

研究组 & 干预措施
External Loop Recorder
This is a non-randomized study. All the patients will be enrolled will received the ELR system.
干预措施: External Loop Recorder (Device)
结局指标
主要结局
The Primary Objective of the Study is to Assess Percent of Participants With Clinically Significant Arrhythmias on ELR Post MI
时间窗: 7 days post discharge
Post MI mortality is higher in India than in the US and Western Europe. The hypothesis of the INSPIRE-ELR study was that occurrence of arrhythmias in the acute phase of MI will identify patients at highest risk and we evaluated the percentage clinical signification arrhythmias captured through the ELR post MI in acute phase
次要结局
- Determine Percentage of Patients With Non-lethal Arrhythmias on ELR Post MI Have a Higher Risk of All-cause Mortality at 1 Year(12 Months)
