Human beings come in different personality types. Personality type is psychological classification of different types of individuals and Personality traits describe the smaller attributes such as behavioral tendencies of a person. While the types
look at qualitative differences between people, the traits take into account the quantitative differences. In a research done by the U.S. National Institute of Aging (NIA), it has been proved that aggressive people have 40% higher risk of hypertension and stroke.
Personality that present itself with aggressive behavior are seen to be more competitive, manipulative, arrogant and self-centered and this behavior pattern reflects in the health of their arteries that supply blood to heart, kidneys and brain - the essential organs of the body. The arteries are more thickened and less elastic or supple making them more prone to hypertension and stroke.
In a recent report from Hypertension: Journal of the American Heart Association, Angelina Sutin lead author of the study done by the NIA, found that in comparison to agreeable individuals, aggressive people
had greater thickening of the carotid arteries (arteries of the neck). Thickening of the carotid arteries is a risk factor for cardiovascular diseases and stroke.
Complications due to arterial wall thickening are slowly progressive and cumulative. It is generally asymptomatic and takes a long time for the symptoms to appear
. However hypertension, chest pain, angina, transient ischemic attacks (TIA) are hints towards diagnosing atherosclerosis.
Arterial walls thicken due to
deposition of plaque (cholesterol
+ lipid products).
This plaque ruptures, leading to formation of a thrombus.
The thrombus can lodge within the vessel and slows or
completely stops the blood flow.
Cessation of blood flow causes tissue
death within 5minutes. This is known as infarction.
When this occurs in the arteries to
the brain, it is termed as stroke and
if it occurs in the arteries of the heart it is called myocardial infarction or
Arterial wall thickening will
reduces the lumen of the vessels and causes the vessels to become less elastic
causing more resistance to the blood flow and this leads to increase in
arterial blood pressure (hypertension).
Though thickening of arterial
walls is a sign of ageing
, people who are aggressive have thickened walls
even at a very young age.
Generally men have thicker
arterial walls than women,
but women who were aggressive soon catch up with
Therefore people with aggressive
behavior should get their cholesterol
levels checked periodically to assess
their cardiac health.
Total Cholesterol should
be less than 200mg/dL
HDL level should be more
than 60mg/dL helps prevent heart diseases
LDL level should be less
than 100mg/dL and less than 70mg/dL for patients who have a cardio-vascular
can determine the extent of arterial wall thickening.
Medical practitioners should look
out for antagonistic or aggressive personality traits
the patients for cardiac health. Intervention at a younger age will prove to be
helpful for antagonistic people. Anger management techniques should be taught
to such people.
The root cause for the aggression
must be ruled out. Consulting a psychiatrist or neurologist
evaluation may be helpful.
So a more tolerant personality type may achieve less
in life but has a better a health advantage and less prone to acquiring
hypertension and stroke
