We've known for a long time that people (especially males) with a Type A personality were more prone to heart attacks, but new information now indicates that general anxiety can also increase the incidence of heart attacks in males by as much as 40%. This means that the social introvert who gets anxious when around people may also be at risk for an increase in heart attacks.
The study was conducted by Dr. Biing-Jiun Shen and published in the Journal of the American College of Cardiology (JACC) in January 2008. Data from a group of 735 healthy men were analyzed for anxiety. The researchers looked at obsessive thoughts, excessive doubts, and irrational compulsions. They also examined fear in social situations (introversion) as well as the degree to which anxiety produced physical symptoms such as tension.
The subjects who scored in the highest percentiles had an increased incidence of heart attacks by as much as 40%.
The study further strengthens the link between mind and body. Your mind is a powerful information source to your body. It is important to pay attention to negative anxiety-provoking thoughts. There are many ways to work on these. I present a number of techniques in my book and there are also stress management classes, exercise, yoga and of course therapy.
