Cerebral Protection

Neurologic Dysfunction is one of the main factors contributing to poor outcomes in cardiac surgery patients, except for heart failure. Atherosclerosis of the aorta, a history of cerebral infarction, and cervical artery disease are common clinical risk factors for cerebral neurological dysfunction after cardiac surgery. Results of preclinical studies suggested that Angong Niuhuang Pills (ANPs), a traditional Chinese patent medicine, including realgar, cinnabaris, Bovis Calculus, artificial Moschus, and powdered buffalo horn extract, decreased infarct volume and cerebral edema, and presented anti- atherosclerosis and cardio-protective effects in clinical and preclinical studies. The PANDA X trial is designed as a pilot study to explore the safety and efficacy of ANP in patients with moderate-to-severe neurologic dysfunction after cardiovascular surgery.
