Principal investigator Dr Gregory Marcus, a UCSF professor of Drugs with the Division of Cardiology stated: ‘It’s additionally intriguing to think about that inhaled substances journey straight from the lungs to pulmonary veins, which empty into the left atrium, and that the pulmonary veins and the left atrium are particularly vital in producing AF.’
