Effectiveness of an eHealth intervention to improve subjective well-being and self-efficacy in cardiovascular disaease patients: A pilot non-randomized controlled trial.

The levels of the experimental group in positive affect, at post-eHealth and follow-up 1, and self-efficacy, at post-eHealth, and both follow-ups, were statistically significantly higher compared to the control group (all ps < .05). When considering sex, the intervention was effective only for men. The results highlight the potential of eHealth interventions for cardiac patients and underline the importance of considering a gender perspective in their treatment.
