Detailed Description
Heart failure (HF) with preserved ejection fraction (HFpEF) occurs in about 50% of all HF patients. Remodeling and fibrosis stimulated by inflammation appear to be main factors for the progression of HFpEF. The lack of prognostic treatment options in HFpEF urgently calls for new therapeutic approaches. While beneficial effects of exercise training have been demonstrated in HF with reduced ejection fraction, they have not yet been evaluated in HFpEF. Therefore, the aim of this study is to investigate the effects of high-intensity interval training (HIT) in HFpEF patients.
The proposed study will be a prospective, single-blind, randomized controlled trial in a primary care setting including 86 patients with stable HFpEF. Patients will undergo 3 study visits (a screening visit, a baseline visit and a post-intervention visit) including measurements of disease-specific biomarkers (using blood samples), cardiac and arterial vessel structure and function (using electrocardiogram, echocardiography, pulse wave velocity, flow-mediated dilation, retinal vessel analysis, cold pressure test), exercise tolerance (using spiroergometry), muscle function (using near-infrared spectroscopy, muscle strength tests), habitual physical activity (using accelerometry) and QoL. After the baseline visit, patients will be randomized to either the intervention or control group. The intervention group (n=43) will attend a supervised 12-week HIT on a bicycle ergometer, while the control group (n=43) will attend a supervised 12-week moderate-intensity continuous training (MCT). After 12 weeks, the study measurements will be repeated in all patients (intervention and control group) in order to monitor the effects of the intervention (post-intervention visit). At 6 months, 1, 2 and 3 years after the last study visit, telephone interviews will be performed to assess medical outcomes and QoL.
Outlook: This study is expected to add important knowledge about the potential utility of a novel treatment strategy in HFpEF patients, which may help to improve both, QoL and functional status. Moreover, the analysed biomarkers might be able to provide further insight into prognosis and pathogenesis of HFpEF.

---|---|
EXPERIMENTAL: High-intensity interval training (HIT)
A 12-week HIT will be performed 3 times per week on a bicycle ergometer according to the protocol of Wisløff et al.
In the first 4 weeks of the program, all sessions will consist of moderate continuous training (MCT) at 60-80% of peak heart rate (HRpeak) for 40 minutes in order that patients get used to exercising.
For weeks 4-12, the following HIT protocol is intended: Patients will warm up for 10 minutes at moderate intensity (60-70% of HRpeak, Borg 11-13) before cycling four 4-minute intervals at high intensity (85-95% of HRpeak, Borg 15-17).
Each interval will be separated by a 3-minute active pause at 60-70% of HRpeak (Borg 11-13).
The training session will end with a 5-minute cool-down at moderate intensity (60-70% of HRpeak).
Total exercise time will be 40 minutes.

Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Change in peak oxygen uptake (VO2peak) due to training
Time Frame: Baseline and 12 weeks
|
VO2peak will be measured by spiroergometry at the baseline and post-intervention visit: an incremental symptom-limited exercise test on an electronically operated bicycle ergometer (eBike, General Electric Company, Fairfield, Connecticut, USA) using a fixed ramp protocol (start at 10 watts, increase of 10 watts/minute) will be conducted.
The test will be performed in an air-conditioned laboratory in the early afternoon under non-fasting conditions.
After a 2-minute warm-up at 10 watts, patients will be instructed to pedal at a constant rate of 60 rpm to exhaustion or until signs of ischemia or serious cardiac arrhythmias appear.
The exercise bout will be followed by a cool-down at 25 watts for 10 minutes or until HR is dropping down below 100 beats/minute.
VO2peak will be defined as the highest value reached during exercise.

|
Baseline and 12 weeks
|
Change in macrovascular function: flow-mediated dilation (FMD)
Time Frame: Baseline and 12 weeks
|
The flow mediated dilation (FMD) is a principle to measure the integrity of the endothelia.
It refers to dilation of an artery when blood flow increases in that artery.
The primary cause of FMD is release of nitric oxide by endothelial cells through shear stress.
Flow-mediated dilatation (FMD) of the brachial arteries provides a non-invasive alternative to other measurement procedures.
To determine FMD, brachial artery dilation following a transient period of forearm ischemia is measured using ultrasound (UNEFEX 38G 3.0, UNEX Co., Nagoya, Japan).
The rationale behind the measurement is that endothelial cells are sentinels of cardiovascular health.
Their function is reduced by the presence of cardiovascular risk factors, and is regained once pathological stimuli are removed
|
Baseline and 12 weeks
|
Change in microvascular function: retinal vessel analysis
Time Frame: Baseline and 12 weeks
|
Static and dynamic retinal vessel analysis will be performed using the retinal vessel analysis system (RVA; IMEDOS Systems, Jena, Germany) and a fundus camera (450 FF; Carl Zeiss, Jena, Germany).
We will take three valid images and two videos of the eye background to quantify retinal microvascular function.
Conventional eye drops (Tropicamide 0.5%) will be used for pupil dilation of one eye, which is necessary for these measurements.
All participants are asked to use public transport because of their dilated pupil.
We recommend not to take part in road traffic for four hours after pupil dilatation.
After this time, the vision should be normal again.
In the first seconds after application of Tropicamide a light and temporary burning irritation or light headache are possible.
|
Baseline and 12 weeks
|
Change in macrovascular function: carotid artery reactivity
Time Frame: Baseline and 12 weeks
|
Carotid artery reactivity (CAR) is a parameter, assessed noninvasively by transcutaneous ultrasound to examine endothelial function following sympathetic stimulation produced by the cold pressor test (CPT).
Right carotid artery diameter is recorded before and during 90 seconds of immersion of the hand up to the wrist in ice water (4°C).
Images will be obtained using a high-resolution ultrasound machine (UF-760AG, 5-12 MHz linear array transducer, Fukuda Denshi Co. Ltd., Tokyo, Japan).
|
Baseline and 12 weeks
|
Change in cardiovascular function: cardiac output
Time Frame: Baseline and 12 weeks
|
The measurement of cardiac output will be performed with Cardioimpedanz (Physioflow, Manatec Biomedical, Poissy, France).
|
Baseline and 12 weeks
|
Change in muscular function: muscle oxygen saturation
Time Frame: Baseline and 12 weeks
|
Muscle oxygen saturation is measured with Near infrared spectroscopy (NIRS, Portamon, Artinis Medical Systems, Elst, The Netherlands).
NIRS relies mainly on two characteristics of human tissue.
First, the relative transparency of tissue to light in the NIR range, and second, the oxygenation-dependent light absorbing characteristics of hemoglobin.
By using a number of different wavelengths, the relative changes in hemoglobin concentration can be displayed continuously and saturation respectively absorption can be measured.
If the absorption is known, the Lambert-Beer law can be used to calculate the chromophore's absorption.
The technique on which NIRS relies is closely analogous to the technique of pulse oximetry and is in consequence not painful and not invasive.
|
Baseline and 12 weeks
|
Change in muscular function: muscle strength
Time Frame: Baseline and 12 weeks
|
The strength test is a so-called Mid-Thigh-Pull Test.
This isometric test is conceptualized in order to rate whole body force.
The force of all extensors of the leg e.g.
M. rectus femoris and of the back such as M. erector spinae as well as muscles of the hand.
The test is comparable to elevate a table by hand.
Two factors will be measured: the ability of a patient to generate maximum force ('Peak Force') and the second factor is measuring the increase of force over time (Rate of Force Development).
