Clinical Trial Summary

Background: Heart failure (HF) is a chronic disease with a very important and increasingly severe social and health impact with a prevalence of 6.8% in Spain. HF with preserved ejection fraction (HFpEF) represents approximately 50% of all patients with HF. In the absence of pharmacological treatments that have succeeded in reducing mortality or morbidity in this pathology, it is recommended that interventions be directed at prevention, symptomatic treatment of HF and treatment of comorbidities to avoid exacerbations, thus physical exercise is recognized as an important adjunct in the treatment of HF and is recommended by the guidelines of the American College of Cardiology (ACC)/American Heart Association (AHA) and the European Society of Cardiology (ESC). Currently, aerobic exercise is the most studied physical exercise in this population, but in recent years high-intensity interval training (HIIT) and the combination of aerobic exercise with strength training (combined exercise) have emerged. Objectives: The overall objective of this study is to compare the effectiveness of combined training and HIIT on exercise capacity, diastolic function, endothelial function, and arterial stiffness in patients with HFpEF. The specific objectives of this study are: a) to compare the effectiveness of combined training and HIIT on quality of life in patients with HFpEF and b) to analyze the cost-effectiveness of combined training and HIIT versus conventional treatment in patients with HFpEF. Methodology: The ExIC-FEp study will be a single-blind randomized clinical trial with 3 arms (combined exercise, HIIT and a control group), conducted at the Health and Social Research Center of the University of Castilla-La Mancha, to analyze two types of supervised physical exercise in patients with HFpEF for 6 months. Patients with HFpEF will be randomly assigned (1:1:1) to the combined exercise, HIIT or control group. All participants will be examined, at baseline (prior to randomization), at three months (mid-intervention) and at six months (at the end of the intervention). Participants will undergo physical examination, echocardiography, maximal cardiopulmonary stress test, and measurement of endothelial function and arterial stiffness. In addition, sociodemographic variables, quality of life, physical activity, adherence to the Mediterranean diet, strength, spirometry and blood sampling will be measured. Expected scientific contributions: this randomized clinical trial will represent a a significant advance in the scientific evidence available on the efficacy of physical exercise in the treatment of HFpEF, through: (a) transfer of the results to physicians, nurses and patients; (b) dissemination of results through scientific articles, doctoral theses and participation in congresses; (c) press releases and press conferences with the aim of disseminating the research results to the population; (d) dissemination through social networks to improve the social impact; and (e) design and content development of a web page.

Intervention

Behavioral:
• Combined exercise
Patients will exercise for 40 minutes three times a week on an ergometric bicycle at 50-60% of VO2max, 60-70% of HRmax, 11-13 on the Borg scale, without ergometer at 50-60% of VO2max, 60-70% of HRmax, 11-13 on the Borg scale, without shortness of breathing difficulty. In addition, strength training will be performed (bench press, leg press, leg curl, leg machine, bench press, leg press, leg curl, leg curl, leg machine). leg curls, leg curls, rowing machine, triceps dips, pectoral pull-ups) twice a week. week. Strength training will be performed with 15 repetitions per exercise and per session, with a corresponding workload of 15 repetitions. session, with a workload corresponding to 60% to 65% of the 1-repetition maximum (1RM) measured at (1RM) measured at the beginning and at the end of the intervention.
• High interval training
Patients will perform three training sessions per week. Each training session begins with a 10-minute warm-up at moderate intensity (corresponding to 50-60% of VO2max, 60-70% of HRmax, 11-13 on the Borg scale, no shortness of breath) before cycling, four 4-minute intervals at high intensity (corresponding to 85-90% of VO2max, 90-95% of HRmax, 15-17 on the Borg scale, shortness of breath). Each interval will be separated by 3 minutes of active pauses, with a HRmax of 50-70%. The training session will end with 3 minutes of cool down at moderate intensity (corresponding to 50-60%). moderate intensity (corresponding to 50-60% of VO2max, 60-70% of HRmax, 11-13 on the Borg scale, without difficulty). Borg scale, no shortness of breath). The total exercise time will be 40 minutes for the HIIT group.
