Depression Doubles Risk Of Death Post Heart Disease Diagnosis, Suggests Study

By  | 

Depression is described as a feeling of severe dejection and misery. Unpredictable emotions like resentment and aggression are harmful for the heart; however, studies reveal that a number of quieter emotions can also be deadly and destructive

A research performed by the Intermountain Medical Center Heart Institute situated in Utah has shown that depression increases the chances of death if one also suffers from heart diseases.

The Details Of The Research

The researchers have focused on the ones who have been suffering from heart problems like steady and unsteady angina. These aliments fall under the category of coronary heart problems, which each year cause the death of 370,000 patients in the U.S.

Studies have shown that heart problems and depression are interrelated to each other. Some studies have also revealed that a patient who is diagnosed with a coronary heart disease is more likely to suffer from depression, when compared to one who does not have heart ailments. This new research is one of the first to throw some light on the causes of depression in the long run.

The investigators had gone through 10 years of the follow-up records of about 25,000 patients of the heart care center. These patients were suffering from coronary heart problems. It was revealed that nearly 15 percent were detected with depression.

These figures are much higher when compared to the general populace among whom only around 7.5 percent to 10 percent suffer from depression.

The Analysis Of The Study

The research shows that 3,646 patients were suffering from depression and about half of them passed away during the duration of the study period. Nearly 20,491 patients were not suffering from depression and only 38 percent of them died during the study.

The researchers carefully reached their conclusion after taking into account variables like gender, other kinds of aliments, heart attack or any kind of chest pain experienced by patients.

After analyzing all the details it was suggested that depression may be the strongest cause of death among heart attack patients. The result is same regardless of the factors like gender, age and the period of onset of depression.

“Our study shows that it doesn’t matter if depression emerges in the short term or a few years down the road — it’s a risk factor that continually needs to be assessed,” said Heidi May, PhD, MSPH, who is the lead author of the study and a cardiovascular epidemiologist at the Heart Center.

The research is about to be presented at The American College of Cardiology’s 66th Annual Scientific Session in Washington, D.C.
