Services offered
Cardiac catheterisation — advice on whether it is needed and, where appropriate, performed in hospital, including percutaneous coronary intervention (balloon dilatation and stenting of a narrowed coronary artery) using modern diagnostics such as intravascular imaging and pressure-wire measurement
Examinations
- ECG (electrocardiogram) — shows whether the heart muscle is currently under-supplied or whether arrhythmias are present
- Cardiac ultrasound (echocardiography) — a routine examination to detect heart disease: pumping function, pressures within the heart and valve competence, together with the detection of valve and heart-muscle disease, blood clots, fluid accumulation and malformations of the aorta or the heart wall
- Ultrasound of the neck vessels (duplex sonography of the extracranial carotid and vertebral arteries) — assesses changes in the vessel wall such as atherosclerotic deposits and narrowing
- 24-hour Holter ECG — an ambulatory recording over 24 hours, used to assess the extent of arrhythmias and to detect those that occur only rarely
- 24-hour blood pressure monitoring — the best method for assessing blood pressure behaviour in everyday life and particularly at night
- Exercise testing (exercise ECG) — detects an under-supply of the heart muscle under exertion, gives information on exercise-induced arrhythmias and blood pressure behaviour, and forms the basis for planning health-promoting endurance training
Cardiovascular prevention — individual advice on optimising lifestyle in order to prevent cardiovascular disease from developing or progressing
Medication management as part of routine check-ups for known cardiovascular disease — based on the latest scientific evidence, drawn from former leadership of the cardiovascular pharmacotherapy working group of the European Society of Cardiology
