Os resultados sugerem que as nanopartículas podem viajar dos pulmões para a corrente sanguínea e chegar a áreas suscetíveis do sistema cardiovascular onde eles poderiam aumentar a probabilidade de um ataque cardíaco ou derrame
Tiny particles in air pollution have been associated with cardiovascular disease, which can lead to premature death. But how particles inhaled into the lungs can affect blood vessels and the heart has remained a mystery. Now, scientists have found evidence in human and animal studies that inhaled nanoparticles can travel from the lungs into the bloodstream, potentially explaining the link between air pollution and cardiovascular disease. Their results appear in the journal ACS Nano.
