- Impact of CSR versus placebo procedure on exertional capacity measured by maximal oxygen consumption (VO2) during cardio-pulmonary exercise testing. [ Time Frame: 6 months ]Maximal oxygen consumption on cycle spiroergometry using the same ramp exercise protocol during the same part of the day.
- Impact of CSR versus placebo procedure on exercise duration time during cardio-pulmonary exercise testing. [ Time Frame: 6 months ]Exercise duration time on cycle spiroergometry using the same continuous exercise protocol during the same part of the day.
- Change in the extent of myocardial reversible ischemia calculated by single-photon emission computed tomography (dynamic scintigraphy). [ Time Frame: 6 months ]Dynamic myocardial scintigraphy with the use of a 4 segment model of the left ventricle for calculation of absolute regional perfusion (ml/g/min) during rest and during pharmacologic stress. Change in the extent of myocardial reversible ischemia calculated by single-photon emission computed tomography.
- Change in the extent of myocardial reversible ischemia calculated by single-photon emission computed tomography (static scintigraphy). [ Time Frame: 6 months ]Static myocardial scintigraphy with the use of a 17 segment model for the relative calculation of regional perfusion during rest and pharmacologic stress.
- Change in RR interval variability as assessed by hrECG. [ Time Frame: 6 months ]5 min recording of hrECG (1000 Hz) for the calculation of RR interval variability.
- Change in late potentials as assessed by hrECG. [ Time Frame: 6 months ]5 min recording of hrECG (1000 Hz) for the calculation of late potentials.
- Change in QT variability as assessed by hrECG. [ Time Frame: 6 months ]5 min recording of hrECG (1000 Hz) for determination of QT variability.
- Change in Canadian Cardiovascular Society angina pectoris class (CCS). [ Time Frame: 3 months, 6 months ]Change in CCS class I-IV. Acco
- Impact of CSR versus placebo procedure on quality of life according to Seattle angina questionnaire (SAQ). [ Time Frame: 3 months, 6 months ]Change in each of the five categories: Physical Limitation Scale (range 1-100), Anginal Stability Scale (range 1-100), Anginal Frequency Scale (range 1-100), Treatment Satisfaction Scale (range 1-100), Disease Perception Scale (range 1-100). Higher values in scale represent better outcome. Subscales are not combined.
- Influence of CSR implantation on echocardiographically assessed left ventricular elastance. [ Time Frame: 6 months ]
- Influence of CSR implantation on diastolic strain. [ Time Frame: 6 months ]
