I read that ppl with panic disorder who have frequent panic attacks are at much higher risk for heart disease. why? does adrenaline damage the heart?

Controversial: Hi This is actually a very controversial issue. Although there are some studies that show association, they do not clearly indicate causality. Excessive amounts and prolonged exposure to "adrenaline" or stimulant medications/drugs are known to damage the heart but panic attacks themselves are not known to cause this level of exposure. Hope this helps
