Summary

This study tested a virtual cardiac rehabilitation program using a smartphone app, a fitness wristband, and a blood pressure monitor for people who recently had a heart attack, heart surgery, or a stent. The goal was to see if this home-based program could improve walking ability, cholesterol, and overall heart health compared to traditional in-person rehab. The trial enrolled 259 adults and followed them for 12 weeks.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance: Corrie Hybrid Cardiac Rehabilitation Program (smartphone app, wristband, blood pressure monitor, exercise bands, health coaching)
What this could lead to: If successful, this could show that a virtual cardiac rehab program is as good as or better than in-person rehab for improving heart health and quality of life.
What could go wrong: This is a completed trial, but it is relatively small (259 participants) and only followed patients for 12 weeks. Results may not apply to all heart patients or show long-term benefits.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * 18 years or older * Individuals admitted to the hospital for the following conditions or interventions during the index admission: Acute myocardial infarction (STEMI or NSTEMI type 1), Coronary artery bypass grafting (CABG), and Coronary artery angioplasty/stenting (PCI), Heart valve surgery, catheter-based aortic valve replacement (TAVR). Exclusion Criteria * Non-English speaking * Symptomatic severe aortic stenosis or other severe valvular disease * Physical disability that would preclude safe and adequate exercise performance * Hypertrophic obstructive cardiomyopathy with peak resting left ventricular outflow gradient of \>25 mmHg * Known aortic dissection * Severe resting arterial hypertension (Systolic blood pressure \>200 mmHg or diastolic BP \>110mmHg) at baseline assessment * Mental impairment leading to inability to cooperate with study procedures * Untreated high degree atrioventricular block * Atrial fibrillation with uncontrolled ventricular rate (Heart rate \>110 at rest) at baseline assessment * History of cardiac arrest or sudden death * Myocardial infarction or cardiac surgery complications with cardiogenic shock and/or congestive heart failure and/or signs/symptoms of post-procedure ischemia * Left ventricular ejection fraction \<40% * History of Clinically significant depression * Visual or hearing impairment which precludes the use of the intervention * Presence of cardiac defibrillator * Incomplete revascularization procedure * History of one or more episodes of falls in the last year * Pregnancy * If patients are deemed clinically unstable and unable to participate at the time of initial screening, the research team member may return at a later date to determine whether this status has changed.
