Key Takeaway
Consider TaCT for potential improvement in functional capacity and quality of life in women with stable cardiac disease.

This randomized controlled trial was conducted in an Indian outpatient cardiology department involving women with stable cardiac disease and smartphone access. The study included n=89 participants divided into intervention and control groups. The intervention group received Technology-based Cardiac rehabilitation Therapy (TaCT), while the comparator group received standard care where cardiac rehabilitation is rare. Follow-up duration was 6 months.

Primary and secondary outcomes favored the intervention for functional capacity and quality of life. Specifically, functional capacity measured by Incremental Shuttle Walk Test showed a 95% CI = 1.0 to -0.2; P = 0.002. Duke Activity Status Index results were significant with P < 0.001, and Sit-to-Stand results showed P = 0.003. Quality of life (global and all subscales) improved with P < 0.001. Heart-health behaviours regarding exercise improved with P < 0.001, and medication adherence showed P = 0.02. Anxiety levels also decreased with P = 0.002. However, there was no significant difference in blood pressure, waist circumference, or cardiac symptoms.

Safety data indicated 3 participants in intervention group experienced morbidity and 1 suffered mortality. In contrast, 9 in controls experienced morbidity only. Key limitations include single-centre design, single-blind methodology, and two parallel arms (1:1 SNOSE). Practice relevance involves demonstrating the potential of technology-based CR tailored for women in middle-income settings. Clinicians should weigh the benefits against the safety profile and study constraints.

A smartphone-based cardiac rehab program designed for women significantly improved their ability to move, reduced anxiety, and boosted healthy habits—especially in places where in-person rehab is hard to access.

Why a Heart Disease Program for Women Matters Now

Heart disease is the leading cause of death for women worldwide. Yet women are far less likely than men to complete cardiac rehabilitation (CR)—a proven program of exercise, education, and support that helps people recover after a heart event.

Why the gap? Many women face barriers: lack of transportation, childcare duties, work schedules, or simply not having a CR program nearby. In lower-income countries, these challenges are even greater.

This study asked: Could technology bridge that gap?

Researchers in India tested a smartphone-based cardiac rehab program designed specifically for women. The goal was to see if a tech-driven approach could deliver the benefits of traditional CR—without requiring women to travel to a clinic.

The Old Way vs. The New Way

Traditionally, cardiac rehab happens in person. You go to a clinic, often several times a week, for supervised exercise, education, and counseling.

But here’s the twist: In many parts of the world, especially in low- and middle-income countries, CR programs simply don’t exist—or are too far away for most women to reach.

This study flipped the model. Instead of bringing women to rehab, it brought rehab to women—through their smartphones.

Think of cardiac rehab like a GPS for your heart. It guides you back to health after a cardiac event.

In this study, the “GPS” was delivered through a phone. Women in the intervention group received a six-month program that included:

  • Exercise plans based on how far they could walk (measured by a simple walking test).
  • Daily check-ins via phone or app.
  • Education about heart-healthy eating, medication, and stress.
  • Support from healthcare workers who followed up by phone.

It’s like having a cardiac rehab coach in your pocket—available anytime, anywhere.

Researchers in India enrolled 100 women with stable heart disease who had access to a smartphone. Half were randomly assigned to the tech-based rehab program; the other half received standard care (which, in this setting, meant little to no structured rehab).

All participants were assessed at the start and again six months later. The main measure was how far they could walk in a standardized test (the Incremental Shuttle Walk Test).

After six months, women in the tech-based rehab group did significantly better than those in standard care.

They walked farther. On average, their walking distance increased by about 30 meters more than the control group—a meaningful improvement in functional capacity.

They felt better. Quality of life scores improved across all areas: physical, emotional, and social. Anxiety levels dropped significantly.

They adopted healthier habits. Women in the rehab group exercised more regularly and were better at taking their heart medications as prescribed.

But here’s what didn’t change: Blood pressure, waist circumference, and cardiac symptoms (like chest pain) showed no significant difference between groups.

Morbidity and mortality: Three women in the rehab group had complications, and one died. Nine women in the control group had complications. The researchers noted this difference but cautioned that the study wasn’t large enough to draw firm conclusions about safety.

This Is Where Things Get Interesting

The program worked—even though it was delivered entirely remotely. That’s a big deal for women who can’t access in-person rehab.

But the study also highlights a key limitation: It was small and short-term. We don’t yet know if these benefits last beyond six months or if the program would work in other countries or cultures.

This study adds to growing evidence that technology can expand access to cardiac rehab, especially for underserved groups. While more research is needed, it suggests that a tailored, phone-based approach could help close the gender gap in cardiac rehab participation.

This program is not yet available as standard care. It was a research study, and more trials are needed before it can be widely recommended.

If you’re a woman with heart disease and you’re struggling to access rehab, talk to your doctor about options. Some clinics may offer virtual or hybrid rehab programs.

The next step is larger, longer-term trials in diverse settings. Researchers also need to explore how to make these programs affordable and accessible to women with limited tech skills or data plans.

If future studies confirm these findings, tech-based cardiac rehab could become a lifeline for millions of women worldwide—bringing heart health support right to their fingertips.

AIMS: Women are under-represented in cardiac rehabilitation (CR), especially in lower-income settings. This study tested Technology-bAsed Cardiac rehabilitation Therapy (TaCT) on functional capacity, risk factors, quality of life (QoL; MacNew), heart-health behaviours (e.g. Global Physical Activity Questionnaire), cardiac symptoms (e.g. angina), and morbidity (e.g. hospitalization and procedure) in women. METHODS AND RESULTS: Single-centre, single-blind, two parallel arms (1:1 SNOSE) randomized superiority trial, undertaken in an Indian outpatient cardiology department, where women with stable cardiac disease and smartphone access were recruited. TaCT was compared with standard care (CR rare), with assessments conducted before the intervention, and 6 months later. The 6-month comprehensive intervention was delivered via several technologies. Exercise prescriptions were based on an Incremental Shuttle Walk Test (ISWT; primary outcome). Analyses were based on intention-to-treat. Fifty women were randomized to intervention, and 50 to control (n = 89; 89.0% retained). There were few tobacco users. Results for the following outcomes favoured intervention: functional capacity [ISWT effect size = 0.3 (95% confidence interval = 1.0 to -0.2), P = 0.002; Duke Activity Status Index P < 0.001; Sit-to-Stand P = 0.003], QoL (global and all subscale P's < 0.001), and heart-health behaviours (exercise P < 0.001; medication adherence P = 0.02), and anxiety (P = 0.002). There were no significant differences in blood pressure, waist circumference, or cardiac symptoms. Three participants in the intervention group experienced morbidity and 1 suffered mortality and 9 in controls experienced morbidity only. CONCLUSION: The TaCT program significantly improved functional capacity, QoL, heart-health behaviours and anxiety in women with cardiovascular disease in a middle-income country, demonstrating the potential of technology-based CR tailored for women in these settings.
