Combined Dietary Education and High-Intensity Interval Resistance Training Improve Health Outcomes in Patients with Coronary Artery Disease.

ABSTRACT:

Background

Reducing cardiovascular risk through lifestyle changes that include a heart-healthy diet and regular exercise is recommended in the rehabilitation of patients with coronary artery disease (CAD). We pilot-tested the effectiveness of a dietary-education and high-intensity interval resistance training (DE-HIIRT) program on healthy food choices and associated anthropometric variables in patients with established CAD.

Methods

A total of 22 participants, aged 60.0 ± 7.2 years, were enrolled in the study. Over 3 months, under the guidance and supervision of a physiotherapist, participants performed the resistance exercises 2×/week in a group setting (cohort of 11). Participants additionally attended three sessions of dietary education led by a dietician. Participants demonstrated their knowledge and understanding of dietary education by picking heart-healthy foods by reading food labels. Outcomes included change in diet (measured using the tricipital skinfold thickness Mediterranean Diet Adherence questionnaire (MEDAS-14) and the Food Consumption Frequency Questionnaire (FCFQ)) and anthropometric measurements (body composition, body circumference, and tricipital skinfold thickness). A paired t-test was performed to analyze the differences between the baseline and post-intervention results.

Results

Participants significantly increased their consumption of vegetables (p = 0.04) and lowered their consumption of sweet snacks (p = 0.007), pastries (p = 0.02), and processed food (p = 0.05). Significant improvements in body mass index (p = 0.001), waist circumference (p = 0.0001), hip circumference (p = 0.04), and body fat (p = 0.0001) were also achieved.

Conclusion

Making lifestyle changes that include both diet and exercise is essential in the management of CAD. The HIIRT program combined with dietary changes shows promise in achieving weight-loss goals in this population and needs to be further investigated with appropriate study designs.

Project description:Ten healthy male participants were recruited and successfully completed all preliminary testing and the two exercise bouts (Figure 1A). This randomized crossover design permitted signaling responses to workload- and duration-matched HIIT and MICT exercise to be mapped and interrogated within the same participant. Baseline whole-body anthropometric and blood glucose and lipid measurements confirmed these participants (age 25.4 ± 3.2 y; BMI 23.5 ± 1.6 kg/m2) were metabolically healthy, and maximal exercise capacity testing confirmed they were recreationally active but relatively untrained (relative V̇O2 peak 37.9 ± 5.2) in line with our recruitment strategy to maximize detection of skeletal muscle signaling responses to exercise (Figure 1B). Peak power output (Wpeak; 207.5 ± 40.3 W) was used to prescribe the relative work-matched intensities for HIIT and MICT. Lean mass from the DXA scan and resting metabolic rate (Figure 1B) were used to prescribe a standardized meal for each participant to consume prior to each exercise trial day. Following consumption of a standardized dinner meal the night before the HIIT or MICT exercise trial, blood and skeletal muscle biopsy samples were collected in the fasted state at baseline and at 5 min and 10 min of each respective exercise intensity. Participants completing the acute bout of HIIT, which consisted of 10 min total of 1-min ‘on’ intervals at 85 ± 0.1% of individual Wpeak (176 ± 34 W) and 1-min ‘off’ intervals at 50 W, displayed increased plasma lactate concentrations at 5 and 10 min of exercise relative to pre-exercise baseline (Figure 1C; P < 0.0001 and P < 0.001, respectively; main effect of time P < 0.0001) and no changes in plasma glucose (Figure 1D). In response to total work- and duration-matched acute bout of MICT at 55 ± 2% individual Wpeak (113 ± 17 W), participants displayed increased plasma lactate concentrations at 5 and 10 min of exercise versus baseline (Figure 1C; P < 0.001; main effect of time P < 0.0001) and no changes in plasma glucose (Figure 1D), with a main effect of higher plasma lactate levels in response to HIIT (Figure 1C; P < 0.05). To map the signaling networks regulated by HIIT and MICT, proteins from each skeletal muscle biopsy sample were extracted, digested to peptides with trypsin, isobarically labelled prior to phosphopeptide enrichment, fractionation and LC-MS/MS phosphoproteomic analysis (Figure 2A).

Project description:BackgroundWith the increasing utilization of cardiac rehabilitation in clinical treatment and prognosis for patients with cardiovascular diseases, exercise training has become a crucial component. High-intensity interval training (HIIT) and moderate-intensity continuous training (MICT) are commonly employed in rehabilitating patients with cardiovascular diseases. However, further investigation is required to determine whether HIIT and MICT can effectively enhance the prognosis of patients with coronary artery disease. Therefore, this study aims to assess the effectiveness of HIIT and MICT interventions, optimal intervention duration for different intensity levels of training, as well as effective training modalities that improve cardiorespiratory function and exercise capacity among patients.MethodsWe conducted a comprehensive search of the Cochrane Library, PubMed, EMbase, Web of Science, and CINAHL databases for randomized controlled trials (RCTs) pertaining to high-intensity interval training (HIIT) and moderate-intensity continuous training (MICT) interventions in patients with coronary artery disease from inception until publication on September 26, 2024. Two independent researchers assessed articles that met the inclusion criteria and analyzed the results using Sata 17.0 software. Forest plots were employed to evaluate the impact of HIIT and MICT on outcome indicators. Sensitivity analysis and funnel plot assessment were performed to examine publication bias. Subgroup analysis was conducted to determine optimal intervention duration and training methods.ResultsA total of 22 studies with 1364 patients were included in the study, including the HIIT group (n = 685) and the MICT group (n = 679). The results showed that compared to MICT, HIIT significantly increased PeakVO2(Peak oxygen uptake)[WMD = 1.42mL /kg/min 95%CI (0.87, 1.98), P = 0.870, I2 = 0%], 6MWT(6-minute walk test)[WMD = 18.60m 95%CI (2.29, 34.92), P = 0.789, I2 = 0%], PHR(Peak heart rate)[WMD = 4.21bpm 95%CI (1.07, 7.36), P = 0.865, I2 = 0%], DBP(diastolic blood pressure)[WMD = 3.43mmHg 95%CI (1.09, 5.76), P = 0.004, I2 = 60.2%]. However, in LVEF(left- ventricular ejection fraction)[WMD = 0.32mL 95%CI (-1.83, 2.46), P = 0.699, I2 = 0%], LVEDV(left ventricular end-diastolic volume)[WMD = 0.91 ml 95%CI (-1.83, 2.46), P = 0.995, I2 = 0%] and SBP(systolic blood pressure)[WMD = 1.85mmHg 95%CI (-0.23, 3.93),P = 0.266, I2 = 18.2%], there was no significant difference between HIIT and MICT.ConclusionBased on the findings of this systematic review, HIIT demonstrates superior efficacy compared to MICT in enhancing PeakVO2, PHR, 6MWT and DBP. However, no significant differences were observed in LVEF, LVEDV, and SBP. In summary, HIIT exhibits potential for improving cardiopulmonary function and exercise capacity among patients with coronary artery disease.
