9. Prognosis
Experts are not sure whether the risk of dying from cor pulmonale is independent of prognosis due to its underlying cause.3Leong, Derek et al. Cor Pulmonale. MedScape (2019). https://emedicine.medscape.com/article/154062-overview However, it is certain that the chance of survival varies depending on the type of lung disease. For example, the five-year survival rate of those with underlying COPD is 30%3Leong, Derek et al. Cor Pulmonale. MedScape (2019). https://emedicine.medscape.com/article/154062-overview.
Death rates of those with massive pulmonary embolism or acute respiratory distress syndrome are unaffected by the presence or absence of cor pulmonale. However, having cor pulmonale increases the mortality risk of pulmonary embolism. Other predictors of death from pulmonary embolism include rapid breathing and heart rate over 100 beats per minute.3Leong, Derek et al. Cor Pulmonale.
