Study information

Study design	Multicentre prospective randomized controlled trial
Primary study design	Interventional
Secondary study design	Randomised controlled trial
Study setting(s)	Not specified
Study type	Quality of life
Scientific title	Exercise training in Diastolic Heart Failure - Pilot study: a prospective, randomised, controlled study to determine the effects of physical training on exercise capacity and quality of life
Study acronym	Ex-DHF-P
Study objectives	Supervised combined endurance and strength exercise training for three months, two to three times/week improves the exercise capacity and quality of life in patients with diastolic heart failure compared to patients in a non-training control group. Please note that as of 01/11/2007 this trial has now been completed. The previous anticipated end date of this trial was 30/09/2008.
Ethics approval(s)	Ethics approval received from the ethics committees of the Universities of Gottingen, Berlin, Munich (Germany) on the 14th September 2006 (ref: 38/9/06), following by amendment 1 on 22nd January 2007 and amendment 2 on 7th March 2007.
Health condition(s) or problem(s) studied	Diastolic heart failure
Intervention	Once randomised, patients will either participate in an combined endurance and strength exercise training two to three times/week for three months or perform their usual activities. After three months and the second visit all patients participate in the training for another three months.
Intervention type	Other
Primary outcome measure	Change in peak maximal oxygen uptake (VO2), measured at 3 months.
Secondary outcome measures	1. Change in quality of life 2. Change in early left ventricular filling-to-peak early diastolic myocardial velocity ratio (E/E' ratio) 3. Change in six-minute walking distance 4. Change in N-Terminal pro-B-type Natriuretic Peptide (NT-proBNP) and other parameters of neurohumoral activation 5. Change in Heart Rate Variability (HRV) and Heart Rate Turbulence (HRT) 6. Change in blood levels of parameters of collagen turnover, metabolic syndrome and inflammation 7. Change in parameters of diastolic dysfunction: 7.1. Early-to-Atrial left ventricular filling ratio (E/A ratio) 7.2. Early left ventricular filling Deceleration Time (EDT) 7.3. Isovolumic Relaxation Time (IVRT) 7.4. Systolic-to-Diastolic pulmonary venous flow ratio (S/D ratio) 7.5. Pulmonary Venous peak Atrial contraction Reversed velocity (PVAR) 7.6. Colour M-Mode flow propagation Velocity (Vp) 7.7. Doppler echocardiography-derived index of myocardial performance (TEI-Index) 7.8. Left Ventricular mass (LV-mass) 7.9. Left Ventricular volume (LV-volume) 7.10. Left Atrial volume (LA-volume) 8. Severity of diastolic dysfunction (echocardiography) 9. Change in endothelial function, safety, compliance, cardiovascular morbidity and mortality Secondary outcomes are measured at 3 and 6 months
Overall study start date	01/10/2006
Completion date	01/11/2007
