Heart Failure + Depression = Bad Chemistry
Now we all know how important it is to not get depressed about your condition so certainly to us this is not surprising however this is a strong step in the right direction to demonstrate the importance of being positive.
Depression could make heart failure even more fatal, a new study suggests.
Researchers from the Mayo Clinic in the US found that people with heart failure who are moderately to severely depressed have a 4x higher risk of death, compared with people with heart failure who are not depressed. They also have a 2x higher risk of being hospitalised or having to go to accident and emergency.
The study shows just how important it is to pay attention to patients’ mental health, as “depression is a key driver of healthcare use in heart failure,” study researcher Alanna M. Chamberlain, Ph.D., M.P.H., an assistant professor of epidemiology at the Mayo Clinic, said in a statement. The new study is published in the journal Circulation: Heart Failure.
The findings are based on 402 people with heart failure, with an average age of 73, who were from three Minnesota counties in the US. The study participants completed a survey with nine questions some time between 2007 and 2010 that analyzed their depression status. Then, the participants were followed for about a year and a half.
Researchers found an association between having depression and risk of being hospitalized or dying in the followup period. The risks went up with severity of depression. For example, according to the survey, people with mild depression were 60% more likely to die, and 35% more likely to have to visit the emergency room than those without depression. They were also 16% more likely to be hospitalised.
However, researchers did note a caveat to the findings. “We measured depression with a one-time questionnaire so we cannot account for changes in depression symptoms over time,” Chamberlain said in the statement. “Further research is warranted to develop more effective clinical approaches for management of depression in heart failure patients.”
Similarly, another new study published in the Journal of the American Heart Association shows that anxiety and depression raise risk of death among people with heart disease. Specifically, anxiety doubles risk of death from any cause among heart disease patients, and patients with both anxiety and depression have a tripled risk of dying. That finding, from Duke University researchers, is based on data from 934 people with an average age of 62.
