Technology-Based Intervention to Promote Heart Health After Cardiac Rehab (Mobile4Heart)

An interventional study of Movn Mobile App in Ischemic Heart Disease, Unstable Angina and Systolic Heart Failure, sponsored by University of California, San Francisco. Completed at 2 sites in United States. Open to participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2025-04-10.

Why
  1. The study's listed conditions name Angina, Unstable, a narrower term within Myocardial Ischemia.
Confidence
High: the new condition is named in the study's own listed conditions. Of 351 hand-checked studies reclassified this way, 68% were exactly right and 84% in the right disease family; the registry's first term was right for 5% (measured 2026-10-21). How we classify →

Study summary

The purpose of this study is to determine whether using a mobile app increases adherence to a heart healthy prescription after discharge from a cardiac rehab program.

Read the detailed description

Ongoing maintenance of physical activity after cardiac rehab is an important part of preventing secondary cardiac events in patients with ischemic heart disease. Our central hypothesis is that monitoring and promotion of health-related behaviors by increasing patient-provider communication through a mobile device after discharge from cardiac rehab increased adherence to a heart healthy prescription over time. Participants will be randomly assigned to use a mobile app or serve as the control group. All participants will have an activity tracker to track their activity for two months.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • At least 18 years of age
  • History of cardiovascular disease that qualified patient for cardiac rehab (i.e. ischemic heart disease, history of unstable angina, systolic heart failure with at 35% or less, and Class II to IV symptoms, coronary artery bypass graft surgery, valve replacement)
  • Own a smartphone or tablet

Exclusion criteria

Exclusion Criteria:

  • Cognitive impairment
  • Lack of English proficiency/literacy
  • Clinical conditions including: unstable arrhythmias, aortic stenosis, thrombophlebitis, dissecting aneurysm, symptomatic anemia, active infection, uncontrolled hypertension (resting diastolic > 100 mmHg, systolic > 180 mmHg), decompensated heart failure class 3-4, current unstable angina, 2nd or 3rd degree heart block, or uncontrolled high grade exercise-induced ventricular ectopy
Terms in these criteria, in plain language(2)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

LVEF (left ventricular ejection fraction)

The share of blood the heart’s main pumping chamber (the left ventricle) pushes out with each beat, measured by an echocardiogram (heart ultrasound) or a MUGA scan. About 50–70% is normal.

NYHA class (heart failure)

The New York Heart Association’s four classes of how much heart failure limits physical activity.

I
No limits: ordinary activity causes no undue tiredness or breathlessness.
II
Slight limits: comfortable at rest, ordinary activity causes symptoms.
III
Marked limits: comfortable at rest, less than ordinary activity causes symptoms.
IV
Symptoms even at rest; any activity makes them worse.

Studies set their own limit — many outside heart failure leave out class III–IV, while heart failure studies may ask for a particular class. Check the class this study names.

What researchers measure

Primary outcomes

  1. Steps Per Day

    Physical activity will be measured by steps per day using activity tracker.

    Time frame: Two months

  2. 6MWT

    Physical activity will be measured by a six minute walk test.

    Time frame: 2 months

Secondary outcomes

  1. PHQ-9

    Depression will be measured by the Patient Health Questionnaire-9 (PHQ-9). Scores range from 0 (lowest) to 27 (highest), higher score associated with moderate to severe depression.

    Time frame: 2 months

  2. Exercise Self-Efficacy Scale (EXSE)

    Self-efficacy will be measured by the Exercise Self-Efficacy Scale (EXSE). Scores can range from 0 (lowest) to 100 (highest) with 0 indicating low self-efficacy and 100 indicating high self-efficacy.

    Time frame: 2 months

  3. Acceptability

    Satification survey, scored 0 (lowest) to 5 (highest), higher score associated with greater satisfaction

    Time frame: 2 months

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Ran from Feb 2018 to primary completion in Apr 2019, 13 months.

Results were first posted in Apr 2025, 6 years after primary completion.

Of 42 non-industry interventional studies with no phase under Angina, Unstable, half reached primary completion within 19 months of starting (the median), counting those still running; a quarter within 12 and three quarters within 44. This study's 13 months is below that.

Counting every sponsor, half of 50 studies reached it within 19 months; a quarter within 12 and three quarters within 44.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Apr 10, 2025, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
