App Summary

Corrie Health is a digital platform that supports patients recovering from a heart attack with tools for medication adherence, vital sign tracking, education, and care coordination. In an effectiveness study (N=1064), patients using the app had a 52% lower risk for all-cause, unplanned 30-day readmissions compared to a historical control group. The associated research concludes that the intervention may improve patient activation for healthcare self-management and lower the risk of readmission following a heart attack.

Detailed Description

Functionality & Mechanism

Developed at Johns Hopkins, the Corrie Health platform is a digital intervention for secondary prevention of cardiovascular events. The system integrates a smartphone application with an Apple Watch and a Bluetooth-enabled blood pressure monitor. Patients engage with modules that facilitate medication adherence, track vital signs, deliver educational content, and coordinate follow-up care. The platform leverages Apple's CareKit and HealthKit APIs to manage recovery progress, biometrics, and deliver scheduled reminders for tasks and appointments.

Evidence & Research Context

A comparative study (N=1064) of patients with acute myocardial infarction (AMI) found the intervention group had a 52% lower risk of all-cause 30-day readmissions compared to a historical control group.
In the same study, patients using the platform demonstrated high levels of activation for healthcare self-management at 30 days post-discharge.
A preliminary pilot study (N=60) established the feasibility of deploying the digital health platform within an acute care setting for patients hospitalized with AMI.
The platform's design, which supports guideline-directed medical therapy, has been demonstrated to be adoptable by patients with limited prior smartphone experience in a published case study.

Intended Use & Scope

The platform is designed for patients recovering from acute myocardial infarction (AMI) for use under clinical supervision. Its primary utility is as an adjunct tool to support self-management and adherence to guideline-directed secondary prevention strategies. The system does not provide medical diagnoses and is not a substitute for professional clinical care.

Effectiveness/Outcome Study

Digital health intervention in acute myocardial infarction

Marvel et al. (2021) · Circulation: Cardiovascular Quality and Outcomes

Heart attack patients using the digital health program had fewer hospital readmissions than those receiving standard care.

Background: Thirty-day readmissions among patients with acute myocardial infarction (AMI) contribute to the US health care burden of preventable complications and costs. Digital health interventions (DHIs) may improve patient health care self-management and outcomes. We aimed to determine if patients with AMI using a DHI have lower 30-day unplanned all-cause readmissions than a historical control. Methods: This nonrandomized controlled trial

Corrie health digital platform for self-management in secondary prevention after acute myocardial infarction: Micore rationale and design

Spaulding et al. (2020) · Circulation: Cardiovascular Quality and Outcomes

Research study planned or in progress; results not yet available

Background: Unplanned readmissions after hospitalization for acute myocardial infarction (AMI) are among the leading causes of preventable morbidity, mortality, and healthcare costs. Digital health interventions (DHI) could be an effective tool in promoting self-management, adherence to guideline-directed therapy, and cardiovascular risk reduction. A DHI developed at Johns Hopkins—the Corrie Health Digital Platform (Corrie)—includes the first

CORRIE: JHU and Apple Collaborate to Bring Cardiac Care to your Fingertips

Dr. Francoise Marvel at Johns Hopkins University developed Corrie Health to address fragmented cardiac care education after heart attacks, creating a CareKit app connected with Apple Watch through collaboration with Apple in Cupertino. The IRB-approved MiCORE study launched at Johns Hopkins Hospital and Johns Hopkins Bayview Medical Center in September, with introductions occurring "while in the hospital on day one." Dr. Marvel and faculty mentor Seth Martin aim to transform outpatient cardiac care coordination through this interactive mobile health tool.
