My name is Grzegorz K. Jakubiak. I am a medical doctor (2017) and a doctor of philosophy (medical sciences, 2022). I work at the Department of Pharmacology in Zabrze, Medical University of Silesia in Katowice, Poland. My main areas of ​​scientific interest include cardiovascular diseases, cardiometabolic diseases (metabolic syndrome and its components), oxidative stress, cardio-oncology, and frailty syndrome issues. My scientific achievements include 51 full-text publications (articles in journals and chapters in scientific monographs) and 79 national and international conference abstracts. I was the first author of most of the published works. According to Google Scholar, my publications have been cited 477 times, and my H index is 9. Current as of August 1, 2024. I have also prepared over three hundred and fifty reviews of scientific articles processed for publication in dozens of journals. I am the Guest Editor of a special issue of the Journal of Personalized Medicine entitled "Cardiology and Vascular Health: Pathophysiology, Therapeutics, and Epidemiology," in which several articles have been published. My particular interests include tools designed to assess subclinical cardiovascular dysfunction (ankle-brachial index, toe-brachial index, intima-media thickness, assessment of vascular stiffness using pulse wave velocity measurement, or evaluation of endothelial function using the flow-mediated dilation method) and their use in various clinical contexts and pathophysiological research. In addition to my scientific work, I am also a professionally active physician in internal medicine. In my daily medical work, I perform ultrasound examinations (echocardiography, peripheral vascular ultrasound, thyroid, and abdominal ultrasound). I also use the above-mentioned methods, along with the assessment of vascular stiffness and peripheral circulation, in my scientific work. I am interested in philosophy, learning foreign languages​​, and traveling.
