About us

Prof. Werner in Darmstadt is a specialist cardiologist at the Darmstadt Hospital GmbH, where he is the Director of Medical Clinic I – Cardiology and Non-surgical Intensive Care. Here, and in a large number of overseas consultations, the specialist cardiologist, Prof. Werner, treats all cardiac and circulatory conditions. Together with the treatment, of course, this also includes examination and diagnosis by the specialist cardiologist.

The emphases of Medical Clinic I under the leadership of Prof. Werner also include intensive care. Here, all life-threatening conditions are treated in the Intensive Care Ward.
In terms of personnel and medical technology, the clinic of the specialist cardiologist, Prof. Werner, in Darmstadt is equipped so that both all investigations and all treatment techniques for cardiac conditions can be carried out. These conditions include, for example, acute constriction (angina pectoris), cardiac failure, cardiac valve defects, congenital cardiac conditions, cardiac dysrhythmias and pulmonary embolus.

The specialist cardiologist, Prof. Werner in Darmstadt, himself, also trades coronary heart disease (CHD), conditions of the atrium or of the cardiac chambers. Here, the treatment emphases of the specialist cardiologist, Prof. Werner, include the re-opening (recanalisation) of occluded coronary vessels, the closure of atrial septal defects by means of a catheter, balloon dilatation of the aortic and mitral valve constrictions or electrophysiological investigation (EPI) and the ablation of cardiac dysrhythmias. Prof. Werner also implants cardiac pacemakers and defibrillators.
Over his long years of practice, the specialist cardiologist in Darmstadt has focused particularly on the most difficult forms of coronary heart disease and long-standing vascular occlusion. In just on 90 per cent of all cases, Prof. Werner in Darmstadt is able to re-open the occlusions by means of a catheter, which enables a great number of major operations to be avoided.
By means of minimally invasive procedures using cardiac catheters, Prof. Werner is able to attain very good success rates in his treatment, and the patients benefit from a shorter treatment duration of, generally, between one and three days.

During his time at the University Hospital in Jena, the specialist cardiologist also devoted himself intensely to the new forms of treatment for severe cardiac insufficiency. At the same time, the use of the most up to date pacemaker systems can promise the affected patients a greater quality of life.
As the Director of the Medical Clinic I, the specialist cardiologist, Prof. Werner, encourages interdisciplinary co-operation, such as close collaboration with the other disciplines of internal medicine at the hospital or with Radiology in order to make the latest diagnostic options in magnetic tomography even more usable for cardiology. Prof. Werner also wants to reinforce the co-operation with Neurology in order to reduce the risk of stroke, since the heart represents a one of the most frequent causes of stroke.

Among the most important tasks of the specialist cardiologist, Prof. Werner in Darmstadt, are the prevention and treatment of myocardial infarct with all its acute and late sequelae. Through this purpose, there should be collaboration with neighbouring hospitals and establish physicians for whom cardiac catheter diagnostics is not available.
Hence, the specialist cardiologist, Prof. Werner in Darmstadt, wants to bring it about that every patient with a suspected cardiac infarct is given the best possible treatment that is available today: cardiac catheter treatment within an hour and around the clock. Collaboration among hospitals in the treatment of cardiac infarct could already be realised to the satisfaction of doctor and patient. The specialist cardiologist also wants to do develop an improvement in the collaboration in the treatment of cardiac dysrhythmias and cardiac defects in order to be able to utilise catheter techniques rather than surgery.

Because of his longstanding professional practice and his diverse expertise in surgical cardiological procedures, the specialist cardiologist, Prof. Gerald Werner, is also in demand overseas. Time and again, the specialist cardiologist and supervises operations abroad in order to act there in an advisory and a practical capacity as a specialist and to pass on his knowledge and experience.
