 (submitted: August 19, 2019)
The Primary Objective of the Study is to Assess Percent of Participants With Clinically Significant Arrhythmias on ELR Post MI [ Time Frame: 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
Original Primary Outcome Measures  ICMJE
 (submitted: November 25, 2013)
Clinically significant arrhythmias reported by ELR at acute monitoring period [ Time Frame: 12 months ]
Change History
Current Secondary Outcome Measures  ICMJE
 (submitted: August 19, 2019)
Determine Percentage of Patients With Non-lethal Arrhythmias on ELR Post MI Have a Higher Risk of All-cause Mortality at 1 Year [ Time Frame: 12 Months ]
Analysis included all patients that completed the acute monitoring period. Based on the arrhythmias detected during the acute ELR monitoring period, patients were classified as "with arrhythmia" when during the ELR monitoring period there is any episode of ELR monitored events listed. All other patients are classified "without arrhythmia". Mortality rates after the monitoring period was estimated for both groups.
Original Secondary Outcome Measures  ICMJE
 (submitted: November 25, 2013)
Clinically significant arrhythmias reported by ELR [ Time Frame: 8-10 weeks post MI ]
The study is designed to collect the incidence of any post-MI arrhythmias. If an arrhythmia is detected, the patient will be managed per the physician's discretion.

Official Title  ICMJE IdeNtifying High riSk Patients Post Myocardial Infarction With REduced Left Ventricular Function Using External Loop Recorders (INSPIRE-ELR Study)
Brief Summary 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.
Detailed Description 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)
