The purpose of this study was to investigate levels of depression and anxiety and their influencing factors in APE patients. Methods Sixty consecutive patients with APE were subjected to investigation of depression and anxiety by the Beck Depression Inventory and State-Trait Anxiety Inventory, and 60 community-based subjects were enrolled as controls. APE patients were stratified as high-risk, intermediate-risk and low-risk according to the disease severity. Scores of depression and anxiety were compared by statistical analysis using paired t tests between APE patients and controls, and by analysis of variance within the APE patients with the three risk stratification. Factors influencing depression and anxiety were evaluated. Results The mean age of the patients （38 males and 22 females） was （52＋12） years. APE patients displayed higher scores of depression （P=0.04） and anxiety （P=0.001） compared with controls. Patients in the high-risk group displayed higher scores of depression （P=0.004） and anxiety （P=0.001） compared with those in the intermediate- and low-risk groups. Depression scores were highly correlated with anxiety scores （r=0.60, P 〈0.001）. Both depression and anxiety inversely related to risk stratification （P 〈0.01）, age （P 〈0.05）, and arterial blood oxygen pressure （PaO2） （P 〈0.05）. Linear regression analysis showed that PaO2 was independently inversely related to both depression （P 〈0.01） and anxiety （P 〈0.05）; risk stratification and age were independently inversely related to anxiety （P 〈0.05）. Conclusions Patients of APE suffered high levels of depression and anxiety, which were negatively influenced by PaO2 risk stratification and age.展开更多

We evaluated the factors causing misdiagnosis of PE as ACS and factors that differentiate PE from ACS to improve the diagnosis efficacy of PE. Methods The medical records of 22 consecutive PE patients, between 2001 and 2010, who were initially suspected of ACS were retrieved. ACS was ruled out by coronary artery angiography before a definite diagnosis of PE was given. Twenty-two contemporary cases of ACS matched by age and sex were recruited as controls. Clinical manifestations, electrocardiograms （ECG）, and biomarkers of these patients were reviewed retrospectively. The factors causing misdiagnosis of PE as ACS and factors differentiating PE from ACS were evaluated. Results We found two leading causes of misdiagnosis of PE as ACS. One is that PE can resemble ACS in several clinical aspects （symptoms and signs, ECG findings, plasma cardiac troponin I, and D-dimer）. The other is the insufficient recognition of PE by clinicians. Risk factors for venous thromboemboiism （VTE）, especially deep venous thrombosis （DVT）, together with signs of PE, such as unexplained dyspnea or hypoxemia, and right ventricular pressure overload on ECGs are valuable in differentiating the two diseases. Conclusions Differentiation between PE and ACS is sometimes challenging. Adequate awareness of the risk factors for VTE and the signs of PE are crucial in the diagnosis of PE.展开更多
