The
human heart is surrounded by blood
vessels called coronary arteries
that supply oxygen-rich blood
and other essential nutrients.
When these blood vessels become
narrow and the blood flow to the
heart is obstructed, a condition
known as Coronary Heart Disease
(CHD) or Coronary Artery Disease
(CAD) arises.
Coronary
Heart Disease is like the Trojan
horse. It infiltrates the body,
progresses over a period of many
years, often unnoticed, and results
in cardiac arrest or heart failure.
Causes and Risk Factors
Coronary heart disease
is essentially caused by atherosclerosis,
wherein there is a gradual buildup
of fatty deposits, calcium, and
scar tissue (plaque) in the coronary
arteries. The arteries become
narrow from plaque deposition
which results in an insufficient
blood supply to the heart. Over
time, the diminished blood flow
may cause chest pain (angina),
breathlessness and other similar
symptoms. A complete blockage
of coronary arteries can lead
to sudden cardiac arrest or heart
attack (myocardial infarction).
Here
are the major risk factors that
may increase the risk of suffering
from coronary heart disease:
|
Age:
Over time plaque may build
up in the arteries and cause
coronary heart disease. |
|
Gender:
Several studies indicate that
men are more likely to suffer
from coronary heart disease
and other cardiovascular diseases
than are women. |
