"As anxiety increases, we start seeing an increase in certain forms of heart disease, we start seeing plaque buildup, and sometimes instability in the arteries of the heart, which can cause heart attacks in people who are heavily stressed," Doshi said.
Doctors say people who are frequently angry or impatient are in a constant state of stress, and the body reacts to that by releasing hormones such as cortisol and adrenaline.
