Coronary artery disease in the ICU may be life-threatening if the condition is critical and more serious complications occur, but the prognosis is still good if no serious complications occur and the treatment is timely. If patients with pulmonary heart disease, combined with pulmonary encephalopathy, respiratory failure, systemic multi-organ failure, disseminated intravascular coagulation and other critical conditions, or can not be separated from the ventilator to complete the independent breathing, then the general prognosis is poor, it is difficult to obtain rehabilitation, to maintain life as the main goal of treatment. However, if there is no combination of such critical conditions, or if the critical conditions are completely controlled through treatment, and the patient can breathe on his own without organ failure, or if the disease is at an early stage, then the impact of pulmonary heart disease on the life expectancy is relatively small, and the patient can generally recover after timely and scientific treatment, and the specific conditions need to be determined by consulting with one’s primary care physician.
