[Analysis of the incidence of syncope and the influencing factors of death in patients with cardiovascular critical emergency].
摘要
OBJECTIVE: To observe the incidence of syncope in patients with acute and critical cardiovascular diseases and to explore the risk factors of death. METHODS: 925 cases of acute heart failure, acute myocardial infarction, pulmonary embolism, arrhythmia and aortic dissection rupture who participated in Prospective, Multi-Center Registered Research Project for Chinese Syncope Patients from March 2018 to March 2020, admitted to the department of emergency of Nanyang Second General Hospital were selected as the research objects. The incidence and mortality of syncope were recorded, and the patients were divided into syncope group and non-syncope group according to whether they were accompanied by syncope or not. The incidence of syncope in male and female patients with different cardiovascular critical diseases, the age and mortality of cardiovascular critical patients with syncope or not were analyzed and compared. Multivariate Logistic regression analysis was used to analyze the risk factors of death, and receiver operating characteristic curve (ROC curve) was drawn to evaluate the predictive value of risk factors on the prognosis of patients. RESULTS: = 10.765, P = 0.010). There was no significant difference in the incidence of syncope between male and female patients with pulmonary embolism, aortic dissection rupture, acute myocardial infarction, arrhythmia and acute heart failure. The age of patients with aortic dissection rupture, acute myocardial infarction and arrhythmia in syncope group were significantly higher than those in non-syncope group [aortic dissection rupture (years old): 66.29±15.64 vs. 57.63±14.23, acute myocardial infarction (years old): 69.55±15.13 vs. 62.10±15.75, arrhythmia (years old): 70.48±14.93 vs. 60.29±16.31, all P < 0.05]. The mortality of patients with pulmonary embolism, aortic dissection rupture, acute myocardial infarction, arrhythmia, acute heart failure in syncope group were significantly higher than those in non-syncope group [pulm
