Abstract:【Abstract】At present, the epidemic of pneumonia caused by 2019 new coronavirus (2019nCov) has entered a severe and complicated situation. The situation of epidemic prevention and control and treatment is very severe. The understanding of the evolution of the new coronavirus pneumonia (NCP) is now unclear. The exact pathogenesis of the disease, especially the mechanism of severe disease, is not fully understood. In this paper, from the perspective of Reninangiotension system (Ras) molecular pathway, the target of ACE2 was used to explore the possible cardiac damage and cardiovascular disease in patients with NCP in 2019ncov.
