Screening examinations are tests performed to find disease before symptoms begin. The goal of screening is to detect disease at its earliest and most treatable stage. In order to be widely accepted and recommended by medical practitioners, a screening program must meet a number of criteria, including reducing the number of deaths from the given disease.
In heart screening, individuals with no signs or symptoms of coronary artery disease — the most common form of heart disease — may be evaluated to measure: the amount of cholesterol carried in the blood known as low-density lipoproteins (LDL)—high levels of which can lead to a buildup in the arteries—and high-density lipoproteins (HDL), which absorb cholesterol and carry it back to the liver, where it is flushed from the body. blood glucose levels, the amount of sugar present in the blood.
The amount of C-reactive protein in the blood with a test called high-sensitivity c-reactive protein assay. C-reactive protein appears in higher amounts when there is inflammation or swelling somewhere in the body. blood pressure levels, the force of blood against the artery walls both when the heart beats and when it is at rest (systolic and diastolic, respectively).
