Prof. Krzysztof Narkiewicz, specialist in cardiovascular diseases, Head of the Department of Hypertension and Diabetology, President of the European Society of Hypertension. He participated in the drawing of the latest European recommendations for the treatment of hypertension. His research has contributed to the discovery of new mechanisms linking disorders of autonomic regulation of the cardiovascular system with an increase in cardiovascular risk. This has led to a better understanding of the role of the sympathetic nervous system in the aetiopathogenesis of cardiovascular diseases. This has important implications for the prevention and treatment of cardiovascular diseases.
