Significance of comorbidities for cardiovascular diseases
Our scientific focus
The influence of comorbidities on coagulation and heart failure
Comorbidities such as diabetes mellitus and chronic kidney disease (CKD) significantly impair the prognosis of patients. Diabetes mellitus is one of the major, continuously increasing public health issues, with approximately 6 million people currently affected by diabetes in Germany. Heart failure is a common complication in patients with diabetes mellitus and is associated with a 7 to 10-fold increased mortality rate. Another risk factor for thromboembolic events and the development of heart failure, which is still only partially understood, is chronic kidney disease. The hearts of patients with diabetes and/or CKD exhibit various metabolic and structural changes, although the molecular mechanisms have not been fully clarified. Consequently, there are no specific therapeutic options available to improve the prognosis of patients with heart failure and diabetes mellitus or CKD. Therefore, we are dedicating ourselves to elucidating the molecular and pathophysiological mechanisms that contribute to the increased cardiovascular morbidity and mortality of patients with diabetes or CKD, both in basic research projects and large clinical studies.
