About this study

Official title: Impact of a Mobile Phone Text Messages Intervention on the Secondary Prevention of Cardiovascular Events After Acute Coronary Syndrome

The study is a two-arm, parallel, randomized clinical trial. The purpose of the study is to evaluate the effectiveness of automated mobile phone text message-based intervention for secondary prevention after acute coronary syndrome hospitalization. Text messages will include information about lifestyle modifications, medication adherence and cardiovascular risk factor control. The participants will be randomized into intervention and control groups in a 1:1 ratio. The intervention group will receive 4 pre-designed and semi-personalized text messages per week in addition to usual care for 6 months, while the control group will receive usual care.

Read the detailed description

Purpose of the trial: The purpose of the study is to evaluate the effectiveness of automated mobile phone text message-based intervention for secondary prevention after acute coronary syndrome hospitalization.

Trial design: Two-parallel arm, single-blind, block randomization.

Primary endpoint: The proportion achieving guideline levels of modifiable risk factors (LDL-C <70mg/dL, blood pressure <140/90 mm Hg, exercising regularly [≥5 d/wk × 30minutes of moderate exercise per session], nonsmoker status, and BMI <25). The investigators prespecified in the statistical analysis plan the efficacy variable of proportion achieving combined risk factor control (achieving risk factor targets in 4 or more of the 5 modifiable risk factors listed above) as a measure of a multiple risk factor effect.

Secondary endpoints: The plasma LDL-C level at 6 months, Level of physical activity, Blood Pressure, Medication adherence measured via Morisky scale, Proportion of non-smokers, Body mass index (BMI), Rates death and hospitalization up to 6 months.

Duration of follow-up: 6 months

Trial treatment:

Intervention: The treatment group will receive the usual discharge treatment, instructions and information for acute coronary syndrome patients as well as the text-messaging intervention. The program will include a variety of topics such as standard follow-up care reminders as well as general self-management and healthy living habits texts. There will be four streams: one for patients who are non-smokers and are free of diabetes; one for current/recent smokers; one for diabetic patients; and one for smoker and diabetic patients. Texts will be sent out 4 times per week for 180 days. All participants in the same stream will receive the same texts in the same order.

Control: The usual care group will receive standard discharge treatment, instructions, and information for patients with acute coronary syndrome. The participants will also receive SMS thanking for their participation in the trial, reminders of trial appointment and informing if they have changed contact details. The frequency of this SMS will be monthly.

Expected sample size, enrollment and expected number of centers:

Sample size = 160 Recruitment start date: November, 2017 Recruitment end date: May, 2019 Follow-up end date: November, 2019 Number of centers: 1

Statistical considerations:

  • Intention to treat analysis
  • The trial has >90% power (2 sided alpha = 0.05) to detect 15% difference in achieving risk factor targets in 4 or more of the 5 modifiable risk factors listed.

    The treatment group will receive the usual discharge treatment, instructions and information for acute coronary syndrome patients as well as the text-messaging intervention. The program will include a variety of topics such as standard follow-up care reminders as well as general self-management and healthy living habits texts. There will be four streams: one for patients who are non-smokers and are free of diabetes; one for current/recent smokers; one for diabetic patients; and one for smoker and diabetic patients.

The usual care group will receive standard discharge treatment, instructions, and information for patients with acute coronary syndrome. They will also receive simple and short text messages related to the importance of trial participation.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Escore of combined risk factor control

    The proportion achieving guideline levels of modifiable risk factors (LDL-C <77mg/dL, blood pressure <140/90 mm Hg, exercising regularly [≥5 d/wk × 30minutes of moderate exercise per session], nonsmoker status, and BMI <25). We prespecified in the statistical analysis plan the efficacy variable of proportion achieving combined risk factor control (achieving risk factor targets in 4 or more of the 5 modifiable risk factors listed above) as a measure of a multiple risk factor effect

    Measured: 6 months

Secondary outcomes (9)
  1. Plasma LDL-C level

    Fasting blood sample

    Measured: 6 months

  2. Level of physical activity (measured via

    Measured by research blinded to treatment allocation - The level of physical activity will be mensured by the International Physical Activity Questionnaire Short Form (IPAQ-SF) and it will be validated in one-fifth of the participants by using accelerometers

    Measured: 6 months

  3. Blood Pressure

    Measured by research blinded to treatment allocation - 3 resting, sitting digital recordings, mean of last 2 readings

    Measured: 6 months

  4. Proportion of non-smokers

    Measured by research blinded to treatment allocation - Self-reported smoking / quitting attempts will be confirmed with a Carbon Monoxide Meter Breath Test

    Measured: 6 months

  5. Body mass index (BMI)

    Measured by research blinded to treatment allocation

    Measured: 6 months

  6. Medication adherence (measured via "Medida de adesão aos tratamentos" - MAT)

    Measured by research blinded to treatment allocation It is an instrument composed of seven items that evaluate the behavior of the individual in relation to daily use of medicines. The answers are obtained by means of a six-point ordinal scale that varies from always (1) to never (6). The values obtained with the answers to the seven items are summed and divided by the number of items (values vary from 1 to 6). Subsequently, values 5 and 6 are computed as one (adherent) and the others are computed as zero (non-adherent).

    Measured: 6 months

  7. Death from any cause

Who may be eligible to take part?

The sponsor lists 3 inclusion and 2 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 14 May 2018. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Brazil. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

How can a doctor refer a patient or contact the research team?

Each site lists its own contact: choose the nearest one under Trial locations. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Escore of combined risk factor control (time frame: 6 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 14 May 2018.
