Arrhythmia:

An arrhythmia is an abnormal rhythm of the heart, which can cause the heart to pump less effectively.

Cholesterol:

Cholesterol is a soft, waxy substance found in all parts of your body. It is used in production of cell membranes, hormones and other needed bodily functions.  But too high a level of cholesterol in the blood is a major risk for coronary heart disease.

Congenital Heart Disease:

A congenital heart defect occurs when the heart or blood vessels near the heart do not develop normally before birth.  Most heart defects either obstruct blood flow in the heart or vessels near it, or cause an abnormal blood flow through the heart.

Congestive Heart Failure:

Congestive heart failure is a condition in which the heart cannot pump out all of the blood that enters it.  This leads to an accumulation of blood in the vessels and fluid in the body tissue.

Heart Attack:

A heart attack, or myocardial infarction, occurs when the blood supply to the heart muscle is blocked or severely reduced.  The reduction or blockage happens when one or more of the coronary arteries supplying blood to the heart muscle is blocked usually by the buildup of plaque.

High Blood Pressure:

Blood pressure is the force of the blood pushing against the artery walls.  When it is measured, two numbers are recorded.  The higher number, the systolic pressure, refers to the pressure inside the artery when the heart contracts and pumps blood through the body.  The lower pressure, or diastolic pressure, refers to the pressure inside the artery when the heart is at rest.  High blood pressure is defined in an adult as a pressure greater than 140 mm Hg (millimeters of mercury) systolic pressure or greater than 90 mm HG diastolic pressure.  The measurement represents how high the mercury rose with the pressure of the blood.  High blood pressure increases the risk of coronary heart disease.
