Brief summary

This study aims to assess the effect of an educational intervention delivered by WhatsApp among participants enrolled in a cardiac rehabilitation program. Both control and intervention groups will receive supervised exercise and short educational lectures. In addition, the intervention group will receive a 4-week educational intervention via WhatsApp. We will assess cardiovascular risk factor knowledge score, physical activity levels, anxiety and depression, and quality of life through self-administered questionnaires at baseline, 4-weeks, 3-month, 6-month and 12-month post-enrollment. Differences between control and intervention groups and pre-and post-intervention periods will be evaluated. We hypothesize that people who receive the structured educational intervention using WhatsApp will show better results in the immediately post-intervention assessment, and these benefits will remain up to 12 months later compared with people who will receive usual care in a cardiac rehabilitation program.

Interventions

The WhatsApp intervention group (16 participants) and the control group (16 participants) will receive the usual care provided by the "Profesionales de la Salud" Rehabilitation center (supervised exercise sessions and short educational lectures). Supervised exercise sessions (Provide to both the intervention group and control group): Participants will receive five 45-minute sessions of exercise per week for 4 to 6 weeks. The number of weeks depends on the number of sessions prescribed by the c

The WhatsApp intervention group (16 participants) and the control group (16 participants) will receive the usual care provided by the "Profesionales de la Salud" Rehabilitation center (supervised exercise sessions and short educational lectures). Supervised exercise sessions (Provide to both the intervention group and control group): Participants will receive five 45-minute sessions of exercise per week for 4 to 6 weeks. The number of weeks depends on the number of sessions prescribed by the cardiologist. Each session will include 5 minutes of warm-up, 30 minutes of moderate-intensity exercise on the treadmill or recumbent bike, 10 minutes of endurance exercise, and finally, a cooldown phase of 5 minutes. The sessions will be conducted in an outpatient clinic located in a tertiary care center called "Complejo Médico FOSCAL." The exercise sessions will be delivered concurrently with respect to the WhatsApp educational intervention. Short educational lectures (Provide to both the intervention group and control group): Participants will receive a 10-minute lecture two times per week over 4 to 6 weeks, depending on the number of sessions prescribed by the cardiologist. The educational lectures will be delivered concurrently with respect to the WhatsApp educational intervention over the same 4-week period and will be provided in groups of no more than 10 participants. WhatsApp Intervention (provide only to the intervention group): In addition, the intervention group will receive the educational intervention by daily WhatsApp messages including videos, images and/or podcasts, explicitly designed for this study. The number of participants in each WhatsApp group will be to a maximum of 4 participants per group. The WhatsApp Intervention will be delivered concurrently over the same 4-week period for those with a 4-week exercise intervention and in the first 4-weeks for those with a 6-week exercise intervention. There will be a theme by week as follows: arterial hypertension, diabetes, smoking and dyslipidemia. The WhatsApp messages will be sent for four weeks from Monday to Friday, at 8:00 AM. Participants will receive an image of the physiopathology related to the weekly theme on Monday, an image with relevant information of the weekly theme on Tuesday, an image and a podcast about nutritional recommendations on Wednesday, a video of physical activity on Thursday, and an image with motivational phrases on Friday. In addition, every day after sending the message, the researchers will solve questions related to the information received by the participants. Adherence to the intervention Adherence to the supervised exercise sessions and short educational lectures will be monitored by an attendance signature. In addition, the providers of the intervention will check the WhatsApp read receipts through the WhatsApp option "read by" at 8 PM every day from Monday to Friday. Providers The physiotherapists and kinesiologists of the "Profesionales de la Salud" Rehabilitation center will deliver the usual care. However, this usual care will not be provided by the research group. Two physiotherapists will deliver the WhatsApp intervention. One of them is specialized in cardiac rehabilitation, completed a Master in education, and is a physiotherapy professor with 12 years of clinical experience in cardiac rehabilitation. The second physiotherapist is specialized in neurorehabilitation, completed a Master of Science in physiotherapy, and is a physiotherapy professor with 14 years of clinical experience in cardiac rehabilitation.
