Cardiovascular disease is the leading cause of morbidity and mortality among women and is frequently associated with changes in sexual function, emotional distress, and reduced quality of life. In women, these difficulties are often influenced by gender-specific factors, including differences in clinical presentation, psychosocial roles, caregiving responsibilities, and the historical under-recognition of female sexuality within cardiovascular care. Although international clinical recommendations highlight the importance of addressing sexual health as part of comprehensive cardiac rehabilitation, this aspect remains insufficiently integrated into routine practice, particularly from a female-centered perspective.

This randomized controlled trial aims to evaluate the effectiveness of a Therapeutic Education Program on Female Sexuality (PET-SF), specifically designed and implemented within a hospital-based cardiac rehabilitation unit. The program is delivered as a structured, group-based, nurse-led educational intervention integrated into usual care. The primary outcome is female sexual function, while secondary outcomes include anxiety, depression, quality of life, and medication adherence. The study seeks to determine whether a gender-sensitive therapeutic education approach can improve sexual well-being and related psychosocial outcomes in women attending cardiac rehabilitation.

Women with cardiovascular disease frequently experience changes in sexual function and intimate relationships following a cardiac event. These changes may be related to physiological alterations, psychological responses such as fear and anxiety, the effects of pharmacological treatment, and sociocultural determinants associated with gender norms. Despite their clinical relevance, sexual health concerns in women are often overlooked in cardiovascular care, and structured, gender-sensitive interventions addressing sexuality are rarely incorporated into cardiac rehabilitation programs.

This study is a unicenter, parallel, randomized controlled trial with a 1:1 allocation ratio, conducted in the Cardiac Rehabilitation Unit of Hospital Universitario Virgen Macarena (Seville, Spain). Adult women referred to cardiac rehabilitation after a cardiovascular event will be randomly assigned to either the intervention group, receiving the Therapeutic Education Program on Female Sexuality (PET-SF) in addition to usual care, or to a control group receiving usual care alone.

The PET-SF is a therapeutic education intervention specifically developed to address female sexuality in the context of cardiovascular disease. It is delivered in a group format by a qualified nurse and is based on a structured educational framework inspired by the EX-PLISSIT model. The program consists of four sessions delivered over approximately four weeks and addresses clinical and psychosocial dimensions such as sexual safety after cardiovascular events, the impact of disease and pharmacological treatment on sexual function, emotional and relational aspects, communication skills, and practical recommendations aimed at facilitating sexual well-being.

Assessments will be performed at baseline (T0), post-intervention (T1, 8-9 weeks), and follow-up (T2, 12-13 weeks). The primary outcome is change in female sexual function measured using the Female Sexual Function Index (FSFI). Secondary outcomes include symptoms of anxiety and depression, health-related quality of life, and medication adherence. The primary analysis will follow the intention-to-treat principle, with complementary per-protocol analyses conducted to assess the robustness of the findings.
