Introduction and Background
At high energy levels, electrohydraulical shock waves (SW) can be used to mechanically desintegrate calculi in the urinary and biliary tract (nephro- and cholelithotripsy). Low intensity SW therapy (SWT) has been shown to increase capillary density and regional myocardial blood flow in animal experiments. We used low energy SWT in patients (pts.) with end-stage coronary artery disease (CAD) not suitable for revascularization, suffering from severe chronic angina pectoris (CCS class III or IV) refractory to individually optimized medical treatment.
