Johan Ärnlöv

Johan Ärnlöv is a Professor of Family Medicine at Karolinska Institutet, Sweden, affiliated with the Department of Neurobiology, Care Sciences and Society. His research focuses on the interplay between kidney and cardiovascular diseases, emphasizing the role of gut and urinary microbiome, as well as chronic pain's impact on cardiovascular outcomes. He leads the Research Group Johan Ärnlöv, collaborating with global consortia like the Global Burden of Disease and Chronic Kidney Disease Prognosis Consortium. Key projects include the microbiome's role in cardiorenal syndromes and cost-effectiveness of CKD screening. He has secured grants from the Swedish Research Council and the Swedish Heart-Lung Foundation. His work spans epidemiology, clinical proteomics, and public health, with over 200 publications in high-impact journals. Notable contributions include studies on cystatin C, biomarkers of cardiovascular disease, and global kidney disease burden analysis.

• Research Areas: Cardio-Renal Syndrome, Nephrology, Cardiology, Chronic Pain, Microbiome Studies
