Low-Density Lipoprotein (LDL) Cholesterol Assessment

At Strong Memorial Hospital, all heart attack patients discharged to home received an LDL cholesterol assessment in 2005.

Cholesterol is a waxy substance that can be found in all parts of the body. It aids in the production of cell membranes, some hormones, and vitamin D. The cholesterol in the blood comes from two sources: foods consumed and the liver. The liver, however, makes enough cholesterol for the body without any additional cholesterol from the diet.

Cholesterol and other fats are transported in the blood stream as round particles called lipoproteins. The two most commonly known lipoproteins are low-density lipoproteins (LDL) and high-density lipoproteins (HDL).

Excessive amounts of cholesterol can cause damage to blood vessels and lead to heart attacks and stroke. Persons hospitalized for a heart attack should receive LDL screening (blood test to determine the amount of harmful cholesterol). According to the National Cholesterol Education Program (NCEP), the goal for LDL is 100 (mg/dl) or less, with lower numbers being more beneficial for disease prevention.
