About

Chronic obstructive lung disease (COPD) is a major cause of morbidity and mortality, and is a major reason for ICU admission. Cardiac function is often impaired in this disease but its association with clinical outcome has not been fully established. The study aims to investigate the association between cardiac dysfunction and clinclial outcomes.

Full description

This is a prospective observational study conducted in a 47-bed mixed ICU of tertiary academic teaching hospital. The study will be performed between January 2014 to December 2015. All patients meeting the diagnostic criteria of AECOPD and admitted to ICU are potentially eligible for the present study. Relevant demographics and laboratory measurements are obtained. Transthoracic echocardiography (TTE) is performed immediately after ICU admission by experienced intensivists. Cox proportional hazard regression model is fitted by using stepwise forward selection and backward elimination technique. If linear assumption is not satisfied, the linear spline function will be used.

Enrollment: 53 patients

Sex: All

Ages: 18+ years old

Volunteers: No Healthy Volunteers
