The Effectivity of the Mobile App "HARKIT I-Care" in Secondary Prevention in Post Acute Coronary Syndrome Patients in National Cardiovascular Center Harapan Kita Hospital

HARKIT I-Care is a mobile application developed by the National Cardiovascular Center Harapan Kita (NCCHK) to leverage patients in achieving their targets for the secondary prevention of cardiovascular diseases. The application contains various features, including exercise tracking and reminder, medication reminder, and updated educational content on cardiovascular health. Additionally, patients can log and record their blood pressure, heart rate, smoking behavior, Quality of Life, and laboratory parameters such as blood sugar and cholesterol. Our research aims to investigate whether implementing this app in post-acute coronary syndrome patients could improve their survival rate, hospitalization rate, medication adherence, and Quality of Life, along with improving their laboratory parameters to be within desirable targets.

Detailed Description

Design: This study is a single-blinded, randomized clinical trial conducted in the National Cardiovascular Center Harapan Kita, and aims to investigate the effect of the mobile application "HARKIT I-Care" on the morbidity and mortality of post-acute coronary syndrome patients.

Subjects: Post-ACS patients hospitalized at the National Cardiovascular Center who are willing to be a subject in this research and have signed the informed consent form. Eligible subjects will be recruited and randomized to two groups: I-Care and control. Subjects in the I-Care group will be instructed to download 'HARKIT I-Care' application on their smartphone. Subjects will then be taught how to use the application, including logging blood pressure, blood sugar, and cholesterol levels, making use of exercise and medication reminders, and where to access health information and teleconsultation. Subjects are instructed to log their health parameters regularly according to the guidebook that has been prepared beforehand. Subjects in the control group will receive education on medication compliance and health information at the beginning of the enrolment. Education was conducted by another research team not involved in assessing outcomes.

Randomization: We conducted stratified permutated block random sampling using a computer application. Stratification used were: (1) Gender: male and female, (2) Age: <65 and ≥65, and (3) Diagnosis: STEMI (ST-Elevation Myocardial Infarction), NSTEMI (Non-ST-segment Elevation Myocardial Infarction), and UAP (Unstable Angina Pectoris). Randomization was conducted using a computer app, and patient assignments were done using a sealed opaque envelope containing the assignment group. Randomization was conducted by a study statistician not involved in data collection. Outcome assessors were blinded to the treatment.

Statistical Analysis plan: We planned on conducting a survival analysis for MACE (major adverse cardiovascular events), cardiovascular mortality, all-cause mortality, and rehospitalization rate. We also intended to analyze the effect of HARKIT I-Care on medication compliance, laboratory parameters, smoking cessation and relapse, sodium consumption, and physical activity.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
No Intervention: Control
Subjects in the control group will receive education on the day of enrolment in NCCHK. Subjects are instructed to take medications and conduct hospital visits as usual.
Experimental: I-Care
Subjects will be instructed to download the "HARKIT I-Care" app from the google play store on their smartphones. Then, they will be guided to create an account and explained how to use the application, including how to log their progress (laboratory parameters and exercise tracking) and how to see messages from their physician. All follow-ups regarding treatment progress, education, and reminders will be done through the app. Patients are directed to conduct hospital visits once per month, where patients will be prescribed cardiovascular medications according to their current condition.
HARKIT I-Care Application is an application available in the google play store. The application is specifically developed for the secondary prevention of cardiovascular disease. The features included in the application are (1) Health information logging, (2) Health information education, and (3) Teleconsultation with a cardiologist. Information that can be logged includes smoking behavior, medications, weight, blood sugar level, blood pressure, cholesterol level, physical activity, and Quality of life. Educational content can be accessed by patients in the form of articles and short videos.
