 This study looked at the post-mortem examinations of 46 people who died from COVID-19 related causes. The results showed that the majority of these patients had diffuse alveolar damage in its early exudative phase as the most common pattern of lung injury. Additionally, other types of lung injury such as bronchonumonia, pulmonary edema consistent with acute cardiac failure, pulmonary thromboembolism and microtrombosis were also identified. This suggests that there are multiple mechanisms involved in the development of COVID-19 related lung injury. Furthermore, the author suggests that the combination of unexpectedly low symptoms, rapid progression of the disease and psychosocial factors could explain why some patients did not seek medical attention before their death.
