Improved Cardiovascular Health for Patients With Inflammatory Joint Diseases

Study Purpose

Inflammatory joint diseases (IJD) are autoimmune diseases with common symptoms of joint inflammation, pain, stiffness and fatigue. Compared to the general population, this large patient-group has an increased risk of cardiovascular disease (CVD) and CVD-related mortality. Patients with IJD call for improved CVD screening and risk management as well as access to evidence-based non-pharmacological treatment alternatives. Evidence supports high intensity training (HIIT) in mitigating risk of CVD and inflammation, but the evidence of these cardioprotective benefits is unclear in patients with IJD and the feasibility of HIIT protocols in daily clinical care needs to be addressed. Cardiorespiratory fitness (CRF) is an important physiological marker and highly correlated to risk of CVD. Despite strong recommendations, routine assessment of CRF is seldom performed in clinical care. The ExeHeart study will assess the potential cardioprotective and disease-modifying effect of HIIT in IJD in a randomized controlled trial. Furthermore, the ExeHeart-study will report on the validity of non-exercise measures of cardiorespiratory fitness (eCRF) measures for use in daily clinical care. Additionally, we will explore the feasibility of HIIT by addressing adherence and fidelity to the HIIT treatment protocol in a primary care setting

Study Type

An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.


An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.


Searching Both is inclusive of interventional and observational studies.

Trial Details

Trial ID:

This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.

 NCT04922840
Phase

Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.

Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.

Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.

Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.

Additional Details

The study is a two-armed randomized controlled trial (RCT). Patients aged 18-70 years presenting with inflammatory joint disease at the Preventive Cardio-Rheuma clinic at Diakonhjemmet hospital (Oslo) will be included if eligible for the study. Succeeding baseline testing, participants are randomized to either experimental group (high-intensity exercise-HIIT) or control group (usual care). The research questions are: 1. Is a 12-week HIIT program effective on VO2peak, inflammatory markers and risk of cardiovascular disease in patients with inflammatory joint disease and what is the association between VO2peak and disease-specific and cardiovascular disease-related variables? 2. Is a non-exercise cardio-respiratory fitness algorithm (eCRF) valid in determining longitudinal change in VO2peak in patients with inflammatory joint disease? 3. How feasible is a HIIT intervention in primary care in patients with inflammatory joint disease in terms of adherence and fidelity to the exercise program? The primary analysis will be a between group comparison of VO2peak levels. This will be carried out according to the intention-to-treat principle, and done by the analysis of covariance (ANCOVA), adjusting for VO2peak values at baseline along with stratification factors used in the randomization. Secondary analyses will include between group comparisons on secondary endpoints, as well as comparisons in the per protocol population. No adjustment for multiple testing will be done. The association between VO2peak and changes in inflammatory markers, disease activity and CVD risk will be assessed using multiple regression. The validity of eCRF models to accurately detect longitudinal change in VO2peak from baseline to 3-month and 6-month follow-up will be assessed with Pearson or Spearman correlation by comparing VO2peak derived from a cardiopulmonary exercise test to eCRF. The feasibility of a HIIT program and adherence will be examined with descriptive statistics. Adherence to the prescribed HIIT intervention will be recorded by attendance to exercise sessions. Quality of treatment delivery will be quantified as the number of exercise sessions complying with the planned exercise intensity and number of exercise sessions requiring dose modifications such as lower exercise intensity or early session termination. At the 3-month timepoint, an electronic questionnaire will be distributed to patients in the HIIT group. Questions regarding feasibility and implementation fidelity will address patients' acceptability and satisfaction with the HIIT program. The ExeHeart study will also include semi-structured interviews, targeting physiotherapists in charge of supervising the exercise sessions and 5-7 patients in the intervention group. The interviews will explore barriers and facilitators in exercise adherence, experience with the protocol and perceived effects of exercise.

Arms & Interventions

Arms

Experimental: High-intensity exercise (HIIT)

Usual care; CVD risk assessment, lifestyle advice (heart-healthy diet, regular exercise, weight management and non-smoking) and relevant medication. The 12-week intervention is carried out as individual or group sessions with maximal 4 patients, supervised by physiotherapists in primary health care. The HIIT group complete two weekly HIIT sessions and a third weekly session with exercise at moderate intensity. Exercise is tailored to each individual to provide the same relative exercise stress and to ensure progression. Target exercise intensity is tracked by a heart rate monitor. Individual exercise session are recorded in a training diary. Succeeding the intervention, a questionnaire will be distributed to patients in the HIIT group. Semi-structured interviews will target physiotherapists supervising HIIT and 5-7 patients in the HIIT group.

No Intervention: Usual care

Control group participants receive the same treatment as usual care; CVD risk assessment including lifestyle advice (heart-healthy diet, regular exercise, weight management and non-smoking) and relevant medication. Control group participants are invited to a physiotherapist-led theoretical and practical HIIT session following study completion.

Interventions

Behavioral: - High-intensity exercise (HIIT)

12 week intervention: Two weekly sessions of 35-40 min exercise: 10 min warm-up, followed by 4x4 min at 90-95% peak heart rate (HRpeak) interspaced by 2-3 min active breaks at 60-70% HRpeak and a third weekly session with continuous exercise for a minimum of 40 min at moderate intensity.
