文摘

The aim of this study is to evaluate the prevalence of depressive symptoms (DS) and its relation on hospitalization for cardiovascular (CV) causes and all-cause mortality risk among outpatients with HF.

Methods

A prospective study was conducted on 130 adult outpatients with HF. The Beck Depression Inventory Scale–second edition (BDI–II) was used to screen for DS. All-cause mortality and hospitalization for CV causes were registered over 6 years. Logistic regression and multinomial logistic regression analysis were used to evaluate the independent prognostic value of DS on mortality and hospitalization for CV causes after adjustment for clinical risk factors.

Results

During a mean follow-up of 6 years, 44% of patients were classified as having DS. Sixty-two participants died for all causes, representing 61% of those with DS and 37% of those without (p=0.006); Forty-nine participants (38%) were hospitalized for CV causes, representing 49% of those with DS and 29% of those without (p=0.027).

Logistic regression analysis indicated that DS predicted all-cause mortality (OR: 2.905; 95% CI:1.228–6.870; p=0.006) and multinomial logistic regression indicated that DS were predictive of hospitalization for CV causes (OR: 3.169; 95% CI: 1.230–8.164; p=0.027). These associations were independent of conventional risk factors.

Limitations

Only outpatient sample; measure of DS only at baseline; cause of death was not known.

Conclusion

This study, first held in a portuguese population, showed that DS are independent predictors of death and hospitalization for CV causes among HF patients and its impact persists over 6 years.
