Prof. Achim Meissner is a specialist in internal medicine and cardiology and in internistic intensive care medicine at the Soest City Hospital, where he has headed the Department of Internal Medicine and Cardiology as its Chief Physician since 2000. In 2012, Prof. Meissner was also appointed as Medical Director of the Soest City Hospital. Since May 2015, he has been a member of the Scientific Advisory Board of the German Heart Foundation. Under the direction of Prof. Meissner, the Department of Internal Medicine and Cardiology of the Soest City Hospital covers the entire treatment spectrum of general internal medicine. Here, the care of patients with cardiac conditions in the context of cardiology forms a particular focus of Prof. Meissner and his team. In particular, acute and chronic conditions of the coronary vessels, including, for example, cardiac infarct or coronary vascular sclerosis, and myocardial insufficiency, resulting from conditions of the cardiac valves or inflammatory and degenerative conditions of the myocardium, are among the treatment emphases of the Department of Internal Medicine and Cardiology. A further treatment emphasis of Prof. Meissner’s team is the diagnosis and treatment of cardiac arrhythmias. The Department of Internal Medicine and Cardiology is equipped with a state-of-the-art left cardiac catheter measuring unit. This enables Prof. Meissner and his team to perform both cardiac catheter examinations and, at the same time, interventional therapeutic techniques such as balloon dilatation or stent implantation. A further focus is the implantation of atrial occluders for patients with atrial fibrillation and existing risk of hemorrhage due to taking oral anticoagulants (blood thinners). In collaboration with the Department of Vascular and Endovascular Surgery, the Department of Internal Medicine and Cardiology also provides the entire spectrum of surgical and interventional therapy for the treatment of vascular conditions. In addition, collaboration with the Bad Oeynhausen Cardiac Center enables the immediate care of patients who require cardiac surgery or complex cardiology therapy.
