 Hi, this is Dr. Anand Shanay, Interventional Cardiologist, Manipal Hospitals, Bangalore. Stress is a common risk factor for a lot of cardiac risk factors, like for example, stress can lead to early onset of diabetes, blood pressure and bad lifestyle. So stress per se primarily does not cause heart disease but it can precipitate a cardiac event which is a heart attack. So stress in absence of any of the traditional risk factors does not cause a heart attack. So a person should have an underlying risk factor for heart disease. So when that is accompanied by undue stress which is pathological can lead to a heart attack. So in our day to day daily life stress is an important factor which keeps our performance to an optimal level. It's undue stress which can cause and lead to trouble. So normal stress is required for our day to day activity.
