That is the link between depression and heart disease?

It is not called a heartbroken for nothing. Many studies have found an association between depression and heart disorders, including arrhythmias, heart attacks, strokes, etc. Some studies have shown associations between the worsening of heart disease in patients who develop depression results (for example, from a heart attack at the depression) while others have found these results simply empirés if one has a history of depression, although depression happened years ago

Surveying 10000 persons over 60 years, a recent study has shown that a single episode of depression at any time of life-prone individual future coronary artery disease. Surprisingly, the number of episodes Exchange not risk - with depression has been as bad as six.What is surprising, is the importance of a nicotine été.Utilisation association and obesity increase the risk of heart disease once and a half, but the depression has proved to be even worse these conditions-it doubled the risk.

If you want a result more surprising, it is this: anxiety disorders increase the risk.

What are the possible explanations? It may be depression causes an increase or decrease in heart of chemicals: for example, depression increased stress and inflammatory cytokines, both which can facilitate the heart hormones. Another explanation is that it is what depression causes make you that leads to heart disease.

It seems that there are two important parameters that determine the risk between depression and heart disease: first of all, if the heart disorder is sudden and acute (such as a heart attack), or stable and chronic (such as current coronary atherosclerosis.)The next parameter is the subtype of depression which predominates: somatic or cognitive.Somatic symptoms include poor sleep, lack of appetite, cognitive symptoms include feelings of guilt and the inability to take advantage of pleasant experiences (called anhedonia).

Seen in this way, it seems that somatic symptoms have an association with a pathology cardiac acute, whereas cognitive symptoms associated with chronic disease.

Would utiles.Par example information, certain types of medication are treating somatic symptoms, and others are more advantageous for cognitifs.Mais symptoms there is an additional conclusion in recent research: when lifestyle factors that predispose the heart problems (such as smoking, obesity, male gender, poor nutrition, poor exercise, etc.) were monitored, association between somatic symptoms and effects of heart diseases coronary disparu.En to pecifies is these other Comorbidities that led to the somatic symptoms of depression.

To home points are as follows: depression leads to heart disease in some way, directly or indirectly, and even an episode may be nocif.Dépression can also predispose to behaviors that lead to heart disease: smoking, eating, sedentary lifestyle, etc.Finally, having certain lifestyles and behaviours that may predispose to heart disease can also lead to depression itself.
