Angina Pectoris Linked to Worse HRQoL in Heart Failure

THURSDAY, Oct. 20, 2016 (HealthDay News) -- For patients with heart failure with reduced ejection fraction, angina pectoris (AP) is associated with worse health-related quality of life (HRQoL) and depressive symptoms, according to a study published in the Oct. 15 issue of The American Journal of Cardiology.

Kishan S. Parikh, M.D., from the Duke Clinical Research Institute in Durham, N.C., and colleagues grouped 2,331 patients with heart failure with reduced ejection fraction from the Heart Failure: A Controlled Trial Investigating Outcomes of Exercise Training trial according to whether they had self-reported AP by Canadian classification score. HRQoL and clinical outcomes by AP status were examined.

The researchers found that 406 patients (17 percent) had AP at baseline; the severity of heart failure was similar to those without AP. Baseline exercise capacity was similar for patients with AP, but depressive symptoms and HRQoL were worse. AP correlated with a 22 percent increased adjusted risk for all-cause mortality/hospitalizations, which was driven by hospitalizations. Baseline AP was significantly associated with exercise training peak maximum volume of oxygen (VO2) change (P = 0.019); there were no correlations for other end points. In patients with AP, exercise training correlated with greater peak VO2 improvements after three months (treatment effect = 1.25 ml/kg/min).

"AP was associated with worse HRQoL and depressive symptoms," the authors write. "Despite greater peak VO2 improvement with exercise training, patients with AP experienced more adverse outcomes."

Several authors disclosed financial ties to the pharmaceutical industry.
