Depressive symptoms are associated with an increased risk of death, but most of this association remains unexplained. Our aim was to explore the contribution of sleep duration and disturbances to the association between depressive symptoms, all‐cause and cardiovascular disease mortality. A total of 5813 (4220 men and 1593 women) aged 50–74 years at baseline, participants of the British Whitehall II prospective cohort study, were included. Depressive symptoms, sleep duration and disturbances were assessed in 2003–04. Mortality was ascertained through linkage to the national mortality register until August 2012, with a mean follow‐up of 8.8 years. Depressive symptoms were associated with an increased risk of mortality from all causes [hazard ratio (HR) = 1.51; 95% confidence interval (CI): 1.16–1.97)] and cardiovascular diseases (HR = 1.63; 95% CI: 1.01–2.64) after adjustment for sociodemographic characteristics. Further adjustment for sleep duration and disturbances reduced the association between depressive symptoms and cardiovascular mortality by 21% (HR = 1.53; 95% CI: 0.91–2.57). Sleep seems to have a role, as a mediator or confounder, in explaining the association between depressive symptoms and cardiovascular mortality. These findings need replication in larger studies with longer follow‐up. 相似文献

Risk stratification of patients with pulmonary embolism represents an important step and may help to guide initial therapeutic management. Pulmonary embolism can be stratified into several groups, with different risk of early death or complications based on the presence of several risk factors. High-risk pulmonary embolism is defined by shock or peripheral signs of hypoperfusion. It is a life-threatening emergency with high short-term mortality (>25%) requiring specific therapeutic strategy with inotropic agents and fibrinolysis. In normotensive patients with pulmonary embolism, the presence of right ventricular dysfunction assessed by echocardiography or myocardial injury based on elevated levels of biomarkers, is associated with an intermediate risk of early death. These patients require close monitoring, and the role of thrombolytic treatment is currently assessed in a large trial. Lastly, patients with normotensive pulmonary embolism and without right ventricular dysfunction or myocardial injury have a low risk of death and complications. These patients may be candidates for home treatment. Several scores combining these risk factors have been described. 相似文献
