A Randomized, Two-arm, Open Label Study to evalUate the Effect of a Smart Phone-based Patient Support Tool On Patient AdheRence of Treatment in Stable Angina Patients Prescribed Beta-blockers in China (SUPPORT)

Study Overview
=================
Brief Summary
-----------------
The present study aims to enhance the adherence of beta-blockers by Patient Support Tool through a smart phone application and a wristband, subsequently reduce the risk of angina attacks in patients with stable angina pectoris.

Detailed Description
-----------------
To control heart rate in terms of guidelines in patients with stable angina pectoris reduces risk of cardiovascular events, rehospitalization, and death effectively. Using beta blockers is an efficient therapy to management the HR in SAP patients. However, the recent epidemiological studies have provided evidences that the rate of beta blocker prescribed and used was inadequate, as the first-line therapy to CAD patients with the usage rate less than 30%. Several studies showed that with a reminder supported by smart phones and wearable devices, the adherence of management of patients with chronic disease could be improved significantly.Thus,the present study aims to enhance the adherence of beta-blockers by Patient Support Tool through a smart phone application and a wristband, subsequently reduce the risk of angina attacks.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Patient support tool group<br>Subjects were managed the HR by using the Patient Support Tool through a smart phone application and a wristband and be guided by physicians | Device: Patient support tool<br>* The patient support tool, a software app installed on the smart phones plus a wrist connected to the smart phones by Bluetooth. The wrist could monitor the pulse, which was recorded to the app in the smart phone. Meanwhile, the app could inform to patients about the importance of medication, remind on the medicine intake, share the patients' data with themselves, and warn the patients if the wrist don't wear.<br>|
| No Intervention: Control group<br>Subjects were received a usual patient care at baseline, which left to the discretion of physicians, without any specific intervention at follow-up period | |

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Adherence to beta-blockers | To evaluate the effect of Patient Support Tool through a smart phone application and a wristband on adherence to beta-blockers in patients with stable coronary artery disease.Duration of treatment-defined as the days the Patient has taken beta-blockers followed the advice of doctors during the 24-week follow up. | 24 weeks | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Impact of resting heart rate | To evaluate the impact of the Patient Support Tool on rHR (resting heart rate).The difference of the average rHR change from baseline between 2 groups. | 24 weeks | 
| Impact of angina attacks | To evaluate the impact of the Patient Support Tool on Angina attacks. The difference of the score change of Seattle angina Questionnaire. | 24 weeks | 
| Major adverse cardiovascular events | To evaluate the impact of the Patient Support Tool on major adverse cardiovascular events (MACE), a composite of cardiac death, myocardial infarction, stroke, and revascularization. | 24 weeks |
