On the one hand, physical training such as High intensity interval training (HIIT) and on the other, eating habits, it is often prescribed to patients with coronary artery disease (CAD). Nevertheless, the combination of HIIT and eating habits in CAD with percutaneous coronary intervention (PCI) there is no consensus on using a combined protocol of both. Purpose. The purpose of this study was to evaluate the impact of an HIIT program with eating habits, with a program based in HIIT, on anthropometric parameters in CAD patients with PCI. Methods. A randomized controlled trial was carried out in a hospital. 44 patients with CAD and PCI were recruited. All participants signed an informed consent. Patients were randomly allocated to a HIIT group (HIIT, n = 22, 81.8% men, 62.05 ± 4.9 years) or to a Dietary education and HIIT (DEHIIT) group (n = 22, 81.8% men, 60.2 ± 5.6 years). HIIT consisted of a 3-month physiotherapy program, twice a week for one hour, at 85-95% peak heart rate. DEHIIT consisted of a multidisciplinary program, including the same HIIT program explained, plus eating habits. Body composition (weight, BMI, % body fat, % visceral fat, muscle mass) and waist circumference, hip circumference and Waste-to-Hip Ratio (WHR) were evaluated at baseline and at week 12. Results. At the end of the program, DEHIIT significantly decreased all anthropometrics parameters except muscle mass. The following parameters decreased: weight (p ≤ 0.001), BMI (p ≤ 0.001), body fat (p ≤ 0.001), visceral fat (p ≤ 0.001), waist circumference (p ≤ 0.001), hip circumference (p = 0.043) and WHR (p ≤ 0.001). Instead, the muscle mass increased significantly (p ≤ 0.001). When comparing between groups, DEHIIT did not show significant differences weight (p = 0.575), BMI (p = 0.404), % body fat (p = 0.217), muscle mass (p = 0.508), waist circumference (p = 0.165), hip circumference (p = 0.307), WHR (p = 0.379), except for presenting less visceral fat (p = 0.040) than HIIT. Conclusions HIIT programme with eating habits reducing visceral fat in CAD patients with PCI compared to a HIIT-only program.
