There is a proven link between Type A personalities and heart disease. If you contantly angry, overworked, and strained, you may be at risk.
In the years since this initial cross-cultural research, countless studies have shown a connection with Type A personality traits and heart disease. Obviously, many different factors can cause heart disease (obesity, smoking, and heredity, just to name a few); in other words, there is no single definitive cause. That said, it has been shown that many people with heart disease have a common problem: they cannot effectively cope with stress. (In fact, Type A personalities often create or invent their own stress.) We generally think of stress as a psychological experience, but it also has significant physical effects. Just as being overweight causes your heart to work harder, stress exerts significant wear on the body.
All of these Type A characteristics contribute to a persistent feeling of stress that is experienced both psychologically and physically. Severely stressed people feel mental strain, but they also might experience physical symptoms like an accelerated heart rate or high blood pressure. This combination of continued emotional and physical distress is, over time, extremely hard on a person's health.
In terms of treatment, doctors have focused on behavioral therapy. Obviously, stress is a permanent fixture in the modern world; most people have to deal with it, and few can avoid it. Since stress prevention is not very practical, psychologists hope to teach Type A personalities better ways to cope with stress. Some of the methods they teach are easy enough to try at home: meditation, deep breathing, and exercise all help people to reduce their stress levels.
The bottom line: if you find yourself feeling angry and pressured all the time, you should find a way to chill out. You will feel happier and keep your heart healthy.
