Is depression associated with poor prognosis in patients with chronic obstructive pulmonary disease - a systematic review?
The results showed that not only is depression a debilitating disease on its own, it also predisposes to COPD exacerbations and increased mortality in patients with COPD. Depression in patients with COPD is under-diagnosed and undertreated, and a stronger focus on the clinical significance of depression as co-morbidity is warranted.
Data from this acute animal study indicate that the use of an endocardial LV pacing electrode may increase the efficacy of resynchronization therapy as compared with conventional epicardial resynchronization therapy.
