Abstract
Objective: An American Heart Association (AHA) Science Advisory recommends patients with coronary heart disease undergo routine screening for depressive symptoms with the two-stage Patient Health Questionnaire (PHQ). However, little is known on the prognostic impact of a positive PHQ screen on heart failure (HF) mortality.
Methods: We screened hospitalized patients with systolic HF (left ventricle ejection fraction≤40%) for depression with the two-item Patient Health Questionnaire (PHQ-2) and administered the follow-up nine-item Patient Health Questionnaire (PHQ-9) both immediately following the PHQ-2 and by telephone 1 month after discharge. Later, we ascertained vital status at 4-year follow-up on all patients who completed the inpatient PHQ-9 and calculated mortality incidence and risk by baseline PHQ.
Results: Of the 520 HF patients we enrolled, 371 screened positive for depressive symptoms on the PHQ-2. Of these, 63% scored PHQ-9≥10 versus 24% of those who completed the PHQ-9 1 month later (P<.001). PHQ-2 positive status was an independent predictor of 4-year all-cause mortality (HR: 1.50; P=.04), and mortality incidence was similar by baseline PHQ-9 score.
Conclusions: Among hospitalized patients with systolic HF, a positive PHQ-2 screen for depressive symptoms is an independent risk factor for increased 4-year all-cause mortality. Our findings extend the AHA's Science Advisory for depression to hospitalized patients with systolic HF.
