Heart Health - Article on Heart Health
"Heart" and the" Circulatory System" are vital organs of
the body. The diseases of heart and circulatory system are
not sudden, but a long-term process is involved.
Major risk factors:
Research has identified three major risk factors associated with
developing heart disease:
- Smoking
- Highblood pressure
- BloodCholesterol
The physiology of the diseases of the heart
The human heart is made of muscles, and they work ceaselessly
from birth to death. It distributes blood to the body and is
responsible for the control of the blood.
The heart receives blood from all over the human body, they
are transported to the lungs for purification purpose, receive it
back from the lungs and then are distributed to the various
parts in the body. The two types of blood, pure and impure are
seperated by a built-in partition. The heart also has four valves
made of soft tissues to ensure that the blood flows only towards
pre-determined directions. The main coronary arteries supply
blood to the heart for its pumping action. For correct functioning
of the heart, the passage of these arteries should be kept free. If
by any reason the passage is blocked or even narrowed, the
heart gets a tardy or inadequate supply of blood and this
becomes an obstacle in the proper functioning of the heart. An
angiography can confirm whether the arteries are blocked or
not.
Effect of high cholesterol and fats
High cholesterol in the blood is a major risk for heart and blood
vessel disease. Although, cholesterol is an essential part of the
body, yet its excess leads to serious heart trouble. Increase of
cholesterol in the blood hardens the arteries and causes death
ultimately. When arteries feeding the heart get blocked, heart
attack occurs. When an artery leading to the brain gets blocked,
a itroke occurs.
Average cholesterol level is between 5.1 and 6.5 according to
the age. A level less than 5:2 normally is desirable. Even more
ideal will be 4.8 or below.
Cholesterol is a unique fatty substance transported through the
blood stream by LDL and HOL carriers. When LDL increases,
the risk of heart becomes greater, which indicates that it will be
deposited in the arteries. When HDL is abundant, risk of heart
attack is lessened.
