Young
men who react to stress with anger are at significantly increased
risk for premature heart disease
Young men who quickly react to stress with anger are at three times
the baseline risk of developing premature heart disease, according
to an American study of more than 1,000 physicians published in the
April 22nd issue of the Archives of Internal Medicine. In addition,
such men -- who said they expressed or concealed their anger, became
irritable or engaged in complaint sessions -- were five times more
likely than their calmer counterparts to have an early myocardial
infarction even without a family history of heart disease.
"In this study, hot tempers
predicted disease long before other traditional risk factors like
diabetes and hypertension became apparent," says Patricia P.
Chang, M.D., lead author of the study. "The most important
thing angry young men can do is get professional help to manage
their tempers, especially since previous studies have shown that
those who already have heart disease get better with anger management."
Chang and colleagues analyzed
data from the Johns Hopkins Precursors Study, a long-term investigation
of 1,337 medical students who were enrolled at Johns Hopkins medical
School between 1948 and 1964 who continue to be followed. In medical
school and through the follow-up period, information on family history
and health behaviors has been collected.
For this report, the investigators
tracked 1,055 men for an average of 36 years following medical school
to examine the risk of premature and total cardiovascular disease
associated with anger responses to stress during early adult life.
During medical school and in 1992, all participants were given a
"nervous tension" questionnaire that sought clues to how
they responded to undue pressure or stress. Expressed or concealed
anger, irritability and complaint sessions were the three responses
defined as indicating the most anger.
When they responded to the
questionnaire during medical school, 229 men said they expressed
or concealed their anger, 169 said they engaged in complaint sessions
and 99 said they were irritable. A total of 21 men reported the
highest level of anger (all three items) in response to stress.
By age 76 years, 205 men (35
percent) had developed cardiovascular disease, with an average onset
at age 56 years. Of those, 145 men had coronary heart disease (94
with myocardial infarction) and 59 reported a stroke. Premature
cardiovascular disease was found in 77 men (8 percent), with an
average onset at age 49 years. Of those, 56 had coronary heart disease
(34 with myocardial infarction) and 13 reported premature stroke.
"Although the number of
heart events was small, the incidence of cardiovascular disease
was significantly higher for those with the highest level of anger
compared with those with lower levels of anger," Chang says.
Although it is not known how anger contributes to heart disease,
Chang says evidence points to stress-related release of extra catecholamines.
