If stress itself is a risk factor for heart disease, it could be because chronic stress exposes your body to unhealthy, persistently elevated levels of stress hormones like adrenaline and cortisol. Studies also link stress to changes in the way blood clots, which increases the risk of heart attack.

Research shows how stress can lead to heart attacks and stroke. Feeling constantly stressed could increase your risk of heart and circulatory disease, according to news coverage. ... The researchers, from Harvard University, suggested stress could be as important a risk factor as smoking or high blood pressure.

I think this topic is controversial . What type of stress are you talking about ?

Although some degree of stress is unavoidable, however, sever and prolonged stress either mental or physical may cause heart attack and stroke. It is interesting to mention that, hypercortisolism (cortisol is a stress hormone) are prone to vascular complications and thromo-embolism which can not be explained by diabetes mellitus and hypertension alone.

Thank u all for your valuable comments.i really appreciate.

1. You have the specific issue of stress cardiomyopathy.

2. Independently of this, a true myocardial infarction may be triggered by heavy exercise and by emotional stress. The pathophysiological mechanism is plaque rupture. Plaque rupture is 2-3 times more frequent during or immediately after strenuous exercise. So yes, emotional stress may elicit a myocardial infarction.

3. In addition, emotional stress may trigger rhythm disturbances. These rhythm disturbances may be fatal in the case of underlying cardiac disease or in the setting of ongoing myocardial infarction.

1)Coronary heart disease is common in individuals subjected to chronic stress.

2)Type A behavior can also increase the likelihood of coronary heart disease.

3)The incidence of heart attacks and sudden death have been shown to increase significantly following the acute stress of natural disasters like hurricanes and earthquakes which evokes “fight or flight’ responses releasing more adrenaline.

Yes

We get angry, do not get angry, the difference is 1 to 3 months life.

In this first study to link regional brain activity to subsequent cardiovascular disease, amygdalar activity independently and robustly predicted cardiovascular disease events. Amygdalar activity is involved partly via a path that includes increased bone-marrow activity and arterial inflammation. These findings provide novel insights into the mechanism through which emotional stressors can lead to cardiovascular disease in human beings.
