The Use of Telemetry following Acute Myocardial Infarction

We aim to investigate time to clinically significant arrythmia episodes on telemetry among patients admitted to hospital with acute myocardial infarction (AMI) and subsequently characterize patients suffering from clinically significant arrythmia after revascularization.

Data will be collected from the electronic patient chart on patients admitted with an AMI during a period from 2017 until 2022. Data collection will include the time from admission to treatment of the AMI to a potential cardiac arrhythmia. Furthermore, patient characteristics will be conducted from patients with clinically significant arrhythmias.

In addition, data from relevant Danish registries and databases will be conducted.

Multicenter cohort study.

Patients ≥18 years admitted with an AMI during a 5-year time-period.

Primary outcome:

Time to any actionable arrhythmic event following PCI.

Secondary outcome:

Type of arrhythmic event. We will conduct subgroup analyses for: Type of infarction, patient characteristics, complete vs. incomplete revascularization, complications during PCI, the presence of heart failure following revascularization etc.

This study will provide important information to help clinical decision making based on data from a contemporary cohort of patients with AMI undergoing revascularization. Identifying the patients who need monitoring and duration of telemetry are of great importance as hospital length of stay and telemetry monitoring incur significant expenses on the health care system. Similar, timely discharge may be important for many patients in the patient-reported outcome era. Ultimately, the result of this study may impact future clinical guidelines.
