Filter by:The main purpose of this study is to examine whether changes in biomarkers during exercise are related to coronary artery disease demonstrated by coronary angiography or echocardiography.
It is the aim of the study to compare the effects of 6 weeks of either high-intensity interval training (HIT; carried out at correctly assessed 85-95% of maximal heart rate), pyramid, or continuous endurance training, on changes of physical exercise capacity in cardiac patients. The three exercise arms (isocaloric) are composed as follows: Endurance training (n=15): 31min at 65-75% HRmax; HIT (n=15): 4x4min intervals at 85-95% HRmax divided by 3x3min of active recovery at 60-70% HRmax, making it a total of 25min; Pyramids (n=15): One Pyramid consists of 8 one-minute blocks. Those are grouped starting with one block of 70-75% HRmax, followed by one block at 75-80% HRmax and another one at 80-85% HRmax. The top of the pyramid are 2 blocks of 85-90% HRmax. Intensity is lowered afterwards with one block at 80-85% HRmax, followed by one block at 75-80% HRmax and last one at 70-75% HRmax. Two more pyramids follow, each divided by 2min of active recovery at 65-70% HRmax, making it a total of 28min. All protocols are initiated by 5min of warm-up and end with 5min of cool-down, both at 60-70% HRpeak. Primary Outcome: Individual maximum power output in watt (Pmax). Secondary Outcome: Change of power output in watt at lactate thresholds at 2 and 4 mmol/l.
The Provisional Heparin TherApy on Radial Artery Occlusion after transradial coronary angiography and patent Hemostasis (PHARAOH) study compares the strategy of standard a-priori heparin use in patients undergoing transradial coronary angiography to a strategy of provisional heparin administration only if patent hemostasis is not achievable.
The aim of the present trial is to assess the efficacy of the standalone use of SeQuent(R) Please coated balloon compared to a bare metal stent (BMS) in patients with NSTEMI.
The purpose if this study is to examine how effective Regadenoson is in detecting coronary artery disease during a stress echocardiogram when Optison is administered. Optison is a contrast agent that improves the images of the heart on the echocardiogram (echo) machine. Optison is approved by the Food and Drug Administration (FDA) to use during stress echocardiograms. Regadenoson is a commercially available rapid acting stress agent that is used to chemically increase the heart rate and is approved for nuclear imaging tests. Regadenoson is a FDA approved drug but not for the intended use in this study.
The purpose of this study is to compare saphenous veins harvested using the atraumatic pedicled ("no-touch") technique to saphenous veins harvested using the conventional open technique in patients undergoing isolated coronary artery bypass surgery. Investigators will compare the biological structure of the saphenous veins harvested using these two techniques. There is some evidence that saphenous veins harvested using the "no-touch" technique may allow for better patency up to 8 years following bypass surgery. We may be able to detect early differences in vascular structure, observed at the time of conduit harvest.
This is a prospective, single-center study that aims to evaluate the acute and delayed effect of exercise stress testing on the peripheral gene expression (PGE) levels using a predefined gene set established in the Corus CAD (Age/Sex/Gene Expression score - ASGES) test in subject with known obstructive coronary artery disease (CAD) and in control subjects (without known CAD).
The purpose of this study is to assess the safety and efficacy of the Danubio Paclitaxel Eluting Balloon for the treatment of side branches of de novo bifurcation lesions in native coronary arteries.
The purpose of this study is to demonstrate that intravenous regadenoson is equivalent to intravenous Adenoscan® for the physiological assessment of intermediate coronary lesions.
The purpose of this study is to determine whether perioperative glutamine administration possess protective properties on internal organs (heart and gut) in patients with coronary atherosclerosis, operated under cardiopulmonary bypass.
