Assessment for risk of developing cardiovascular disease, major adverse cardiovascular events, or ischemic cerebrovascular events

Clinical Information
Discusses physiology, pathophysiology, and general clinical aspects, as they relate to a laboratory test

Cardiovascular disease remains the leading cause of morbidity and mortality despite well-defined risk factors and treatment strategies. Atherosclerosis, the underlying cause of cardiovascular disease, is a buildup of plaque within arteries. This buildup of plaque can lead to chronic or acute restrictions in blood flow resulting in heart attacks and strokes. Many of these events occur in individuals with no prior symptoms. Standard risk factors include age, smoking status, hypertension, diabetes, total serum cholesterol, and high-density lipoprotein cholesterol.

 

Apolipoprotein B (ApoB), high-sensitivity C-reactive protein (hsCRP), and lipoprotein (a) (Lp[a]) are serological risk factors endorsed by multiple international guidelines for use in cardiovascular disease risk assessment. Several recent guidelines have suggested that clinicians utilize ApoB, hsCRP, and Lp(a) in selected persons to augment risk classification, guide intensity of risk-reduction therapy and modulate clinical judgment when making therapeutic decision.(1-3)

Interpretation
Provides information to assist in interpretation of the test results

Specific interpretations are provided based on lipid results according to Mayo Clinic care process models. Mayo Clinic has adopted the National Lipid Association classifications, which are included as reference values on Mayo Clinic and Mayo Clinic Laboratories reports (see Reference Values).

 

More aggressive treatment strategies may be pursued in patients determined to be at increased risk.

Cautions
Discusses conditions that may cause diagnostic confusion, including improper specimen collection and handling, inappropriate test selection, and interfering substances

Lipid values should be considered in the context of clinical presentation. Additional risk factors include cigarette smoking, hypertension, age and personal or family history of cardiovascular disease.

 

Result can be falsely decreased in patients with elevated levels of N-acetyl-p-benzoquinone imine (NAPQI)-a metabolite of acetaminophen, N-acetylcysteine (NAC), and metamizole.

Method Description
Describes how the test is performed and provides a method-specific reference

The following calculations are performed in the laboratory information system, SCC Soft.

Non-high-density lipoprotein (HDL) cholesterol = Total cholesterol – HDL cholesterol

Low-density lipoprotein (LDL) cholesterol = Total cholesterol - HDL cholesterol - (Triglycerides/5)

 

HDL Cholesterol:

Non-HDL lipoproteins such as LDL, very low-density lipoprotein (VLDL) and chylomicrons are combined with polyanions and a detergent forming a water-soluble complex. In this complex the enzymatic reaction of cholesterol esterase (CHER) and cholesterol oxidase (CHOD) towards non-HDL lipoproteins is blocked. Finally, only HDL-particles can react with CHER and CHOD. The concentration of HDL-cholesterol is determined enzymatically by CHER and CHOD. Cholesterol esters are broken down quantitatively into free cholesterol and fatty acids by CHER. In the presence of peroxidase, the hydrogen peroxide generated reacts with 4-amino-antipyrine and N-ethyl-N-(3-methylphenyl)-N'-succinylethylenediamine) to form a dye. The color intensity of this dye is directly proportional to the cholesterol concentration and is measured photometrically.(Package insert: HDL-Cholesterol Gen4. Roche Diagnostics; V 2.0, 08/2018)

 

Total Cholesterol:

Cholesterol esters are cleaved by the action of cholesterol esterase to yield free cholesterol and fatty acids. Cholesterol oxidase then catalyzes the oxidation of cholesterol to cholest-4-en-3-one and hydrogen peroxide. In the presence of peroxidase, the hydrogen peroxide formed effects the oxidative coupling of phenol and 4-aminophenazone to form a red quinone-imine dye. The color intensity of the dye formed is directly proportional to the cholesterol concentration. It is determined by measuring the increase in absorbance.(Package insert: Cholesterol Gen2 Reagent. Roche Diagnostics; V 10.0, 03/2020)

 

Triglycerides:

This test uses a lipoprotein lipase from microorganisms for the rapid and complete hydrolysis of triglycerides to glycerol followed by oxidation to dihydroxyacetone phosphate and hydrogen peroxide. The hydrogen peroxide produced then reacts with 4-aminophenazone and 4-chlorophenol under the catalytic action of peroxidase to form a red dyestuff (Trinder endpoint reaction). The color intensity of the red dyestuff formed is directly proportional to the triglyceride concentration and can be measured photometrically.(Package insert: Triglycerides. Roche Diagnostics; V 9.0, 01/2020)

 

Lipoprotein (a):

This test is a particle enhanced immunoturbidimetric assay. Human lipoprotein (a)(Lp[a]) agglutinates with the latex particles coated with anti-Lp(a) antibodies.(Package insert: Lipoprotein (a) Gen.2 reagent. Roche Diagnostics; V2.0, 01/2015)

 

C-Reactive Protein:

Particle-enhanced immunoturbidimetric assay. Human C-reactive protein (CRP) agglutinates with latex particles coated with monoclonal anti-CRP antibodies. The precipitate is determined turbidimetrically.(Package insert: Cardiac C-Reactive Protein (Latex) High Sensitive. Roche Diagnostics; V 12.0, 03/2019)

 

Apolipoprotein B:

Anti-apolipoprotein B antibodies react with the antigen in the sample to form antigen:antibody complexes, which, following agglutination, can be measured turbidimetrically.(Package insert: Tina-quant Apolipoprotein B, Roche Diagnostics; V1.0 07/2020)
