Researchers at Cardiavent Inc. were the first to elucidate novel actions of vitamin D receptor in the regulation of renal and cardiovascular function and health.  These reports demonstrated the importance of Vitamin D for human renal and cardiovascular health. Cardiavent Inc. is now focused on the development of a selective vitamin D receptor agonist/analog [SVDRA] CARD-024 for treatment of renal and cardiovascular diseases including secondary hyperparathyroidism, cardiac fibrosis, hypertrophy and hypertension.
