Having both depression and type 2 diabetes increases the risk of death for heart patients. Each factor had been known to increase the risk of heart disease deaths by itself, but together they’re even more deadly.
In an analysis of more than 900 patients with established coronary artery disease, Duke University Medical Center psychologists found that those with both type 2 diabetes and symptoms of depression were more likely to die than heart patients without those conditions.
The study showed that among type 2 diabetes patients, having high depression scores increased the risk of dying by 20 to 30 percent compared to patients with similar depression scores but no type 2 diabetes.
“We found a trend showing that the probability of death increases as the level of depression increases in diabetic patients with coronary artery disease,” said Duke researcher Anastasia Georgiades, Ph.D. “Our data appear to show an important interaction between type 2 diabetes and depression, meaning that physicians should closely monitor their heart patients who have both of these disorders.”
“There is some sort of synergistic effect between type 2 diabetes and depression that we don’t fully understand,” Georgiades said. “In our analysis, we controlled for factors that could influence mortality, such as heart disease severity and age. For whatever reasons, these patients were still at higher risk of dying, and future research will aim to investigate the mechanisms for this association.” The research was supported by the National Heart, Lung, Blood Institute.
The researchers followed 933 heart patients for more than four years and correlated the 135 deaths that occurred during that period with the presence of type 2 diabetes and depression alone and together.
Georgiades said there are some possible explanations for the link between depression and diabetes.
“Patients with type 2 diabetes typically have an extensive self-care regimen involving special diet, medications, exercise and numerous appointments with their doctor,” she said. “It may be that such patients who are depressed might not be as motivated to carry out all these activities, thereby putting them at higher risk.”
Depression has also been linked to other cardiovascular risk factors such as insulin resistance, hypertension, obesity, increased cigarette smoking, alcohol abuse and physical inactivity.

It is said that psychology is the first and basic reasons for all occurring diseases and health problems. It means there is very close relationship between mind (psychology) and diseases. And so heart attack or heart disease in the exceptional disease. Every patient of each disease comes under pressure. It is observed that almost 50% patients of heart disease have symptoms of depression. 20% heart patients who suffer from depression can be cured with antidepressants.
While antidepressants can improve mood by boosting the better chemicals in the brain, they do not treat the real cause of the depression. Because of this, decline rates are high once drug treatment is stopped. In difference, the emotional insights and coping skills obtained during therapy can have a more lasting effect on depression.
In other words, antidepressants also play important role for heart patients. It is also come to know that some heart patients would die due to depression at the hospitalization time. This ratio is 2 to 5 times more likely than average to suffer further conditions or to die. Reappearance of cardiovascular is closer to depression than smoking, diabetes, cholesterol, or high blood pressure.
Mind and mood both factors affect the cardiovascular method. The instant reactions of damaging blood vessels, sensation of heart, become constants or even slow if the heart patient is seriously anxious or depressed. Selective antidepressants like serotonin (serotonin reuptake inhibitors SSRI) are very useful for the heart patients. Sometimes such antidepressants can also reduce the future heart problems and save lives.
Heart specialists often prescribe antidepressants that helps to reduce the depression so that they can care themselves better. However, it is difficult to declare effects and reasons in the link between heart disease and depression. Even though the symptoms of both heart disease and depression might be same but the instant study of the case is different. Heart specialist can ask the patients about their depression, stress. At this time patients should provide proper and real information so that doctor could prescribe better antidepressants.
Keep in mind, SSRIs, do not prevent heart attack completely but can definitely reduce the degree of the disease. Antidepressant treats the depression and patient becomes relax and danger can be avoided. Whether to use antidepressants or some other mechanism should use, is determined after studying the case clearly. Many times doctors prescribe SSRIs to reduce the heart attacks only. This is simple and first purposes to prescribe the SSRIs.

Severe depression may silently break a seemingly healthy woman’s heart.
Doctors have long known that depression is common after a heart attack or stroke, and worsens those people’s outcomes. Today, Columbia University researchers reported new evidence that depression can lead to heart disease in the first place.
The scientists tracked 63,000 women from the long-running Nurses’ Health Study between 1992 and 2004. None had signs of heart disease when the study began, but nearly 8 percent had evidence of serious depression.
The depressed women were more than twice as likely to experience sudden cardiac death — death typically caused by an irregular heartbeat, concluded the 12-year study, published today in the Journal of the American College of Cardiology. They also had a smaller increased risk of death from other forms of heart disease.
The big surprise: Sudden cardiac death seemed more closely linked with antidepressant use than with the depression symptoms the women reported.
That might simply mean that women who used antidepressants were, appropriately, the most seriously depressed, cautioned lead researcher Dr. William Whang. But he said the finding merited more research.
Studies of the newer antidepressants most often used today so far haven’t signaled a risk of irregular heartbeat, and some even have suggested protection, noted Dr. Redford Williams of Duke University, a specialist in how psychosocial factors affect health.
The drug question aside, Williams said the work adds to growing evidence that depression is an independent risk factor for heart disease — on top of the classic risks of high blood pressure, diabetes, high cholesterol and smoking.
The predominantly white Nurses’ Health Study may underestimate it, Williams said. “If anything, the impact in African-American women is probably greater,” he said, adding that it’s time for the next step: A study testing whether properly treating depression lowers the risk.
Why might depression have that effect? The study found that the more severe the women’s reported depression symptoms, the more likely she was to have traditional heart risk factors. Also, stresses like depression have been linked to such physical effects as a higher resting heart rate.
Perhaps a more straightforward reason: Depression can make people do a worse job taking care of themselves. Indeed, the American Heart Association last year recommended that everyone who already has heart disease be regularly screened for depression — because depressed patients may skip their medications, sit indoors instead of exercising, and eat particularly poorly.
