A new Norwegian study found a link between depression and heart failure.
Researchers used data from nearly 63,000 people in Norway who had both physical and mental health reviews. Over the course of 11 years, nearly 1,500 participants had developed congestive heart failure. Compared to those who showed no signs of depression, participants with mild symptoms were 5 percent more heart failure develop and with moderate to severe symptoms of depression 40 percent were more likely to congestive heart failure develop.
"Depressive symptoms increase the likelihood for the development of congestive heart failure and symptoms are heavier, the greater the risk," said the study first author Lise Tuset Gustad, one intensive care nurse at hospital Levanger in Norway.
"Depressed people have less healthy lifestyles, so adjusted our analysis to factors such as obesity and smoking, which cause that depression and heart failure." "This means that we can be sure, that these factors is not the cause of the Association."
It is important to note that the study does not say that depression simply causes congestive heart failure, that the two are linked.
"Depression trigger stress hormones. If you stressed, feel your heart rate to rise and your breathing speeds up, the result of the hormones released. These stress hormones cause inflammation and [plaque deposits in arteries], can the cardiovascular, speed "Gustad said.
It adds that those who are depressed have greater difficulty with following advice on medicines, or improving the overall life style.
