Heart Disease Risk Factors
Lifestyle risk factors that can be prevented/changed:
Carbon monoxide attaches to the hemoglobin of the blood. Hemoglobin is
responsible for the transport of oxygen throughout the body. Carbon
monoxide replaces the oxygen, thus reducing the ability of hemoglobin to
transport oxygen to the heart and throughout the rest of the body.
Nicotine stimulates adrenaline production, which causes the heart to beat
faster and thus raises blood pressure.
Obese people have more fat in their bodies. The fat lines the blood
vessels and makes the passage of blood harder. This means the
heart has to work harder to get blood to all the organs in the body.
Alcohol can cause high blood pressure and weakens heart
muscles, which can affect lungs, liver, brain and other body
systems and can cause heart failure. Binge drinking and
drinking heavily over longer periods can cause the heart to
beat irregularly and has been linked to cases of sudden
Raised blood pressure damages arteries leading to the
heart and reduce blood reaching the heart. Leads to
angina and if continued, and over time, the damage caused by the
extra blood pressure may burst the arteries or become completely
clogged. If this happens, then the part of the heart that was receiving the blood no
longer gets the oxygen and nutrients it needs and dies. The result is a heart attack.

Here's a taster:
Age - The risk of heart attack increases with age.
Gender - Men are at a higher risk than women.
Ethnicity - Some ethnic groups have increased risk of known contributors to
coronary heart disease.
Genetics - Family history is one of the major risk factors for coronary heart disease
and heart attacks, and common genetic variants have been found that are associated
with increased risk.…read more
