Yet and remain underrecognised and undertreated in patients with heart failure, said Christopher Celano, of in the US.

"Diagnosing a can be challenging in view of the significant overlap" between psychiatric symptoms and those related to heart failure, Celano said.

Nevertheless, "making the effort can help to identify those who are at higher risk for poor cardiac outcomes and to implement the treatment of these disorders," he said.

Previous studies have linked to worse outcomes in patients with To clarify these relationships, researchers performed a targeted review of research on associations between heart failure, depression, and

Studies have reported that one-third of heart failure patients report elevated symptoms of depression on standard questionnaires, while 19 per cent meet diagnostic criteria for major depression or other

"Depression has been linked to the development and progression of heart failure and other cardiovascular diseases," Celano said.

Studies suggest not only that heart failure patients with depression are at increased risk of death or cardiac events, but also that otherwise healthy adults with depression are more likely to develop heart failure.

Anxiety is also highly frequent among patients with heart failure: nearly 30 per cent of patients have clinically significant anxiety symptoms, while 13 per cent meet diagnostic criteria for (such as generalised anxiety disorder, posttraumatic stress disorder, or panic disorder).

Some studies have linked anxiety to outcomes, although the evidence is less consistent than for depression.

Both physiological and behavioral factors may contribute to adverse outcomes. Depression and anxiety may make it more difficult for patients with heart failure to follow recommendations for diet, exercise, and medication use.

Studies have also linked depression to metabolic changes, including increased levels of
