Insights
Traditional lipid profiles can help screen for cardiac events when troponin testing isn't available. Elevated cholesterol and triglycerides, with reduced HDL, indicate higher risk in patients with chest pain.
Area of Science:
- Cardiology
- Biochemistry
Background:
- Cardiac events often present with chest pain.
- Troponin I testing confirms myocardial damage.
- Lipid profiles assess cardiovascular risk factors.
Purpose of the Study:
- To evaluate the utility of traditional lipid profiles in identifying cardiac events.
- To compare lipid profiles in patients with and without confirmed cardiac events.
Main Methods:
- Retrospective analysis of 430 patients with cardiac ischemia symptoms.
- Comparison with 165 healthy controls.
- Analysis of troponin I, total cholesterol, HDL, VLDL, and triacylglycerol levels; LDL calculated via Friedewald's formula.
Main Results:
- Patients with confirmed cardiac events (positive troponin I) showed significantly higher total cholesterol, triacylglycerol, and LDL levels.
- These patients also had significantly lower HDL cholesterol levels compared to controls and those with negative troponin tests.
Conclusions:
- Traditional lipid profiles remain valuable for screening populations at risk for cardiac events.
- Lipid profiles can be used in settings lacking troponin testing facilities.
Objective:
To study the usefulness of traditional lipid profile levels in screening subjects who had developed chest pain due to cardiac event as indicated by a positive troponin I test.
Methods:
In this retrospective study data of the 430 patients presented to the emergency department with symptoms of cardiac ischemia who underwent both troponin and lipid profiles tests were compared with the lipid profiles of 165 normal healthy subjects (controls). The troponin was detected qualitatively when a specimen contains troponin I (cTnI) above the 99th percentile (TnI>0.5 ng/mL). The total cholesterol, high density lipoproteins cholesterol, very low density lipoproteins and triacyl glycerol levels were also analyzed and low density lipoprotein level was calculated using Friedewald's formula.
Results:
Patients with chest pain and positive troponin test (with confirmed cardiac event) were found to have significantly elevated levels of total cholesterol, triacyl glycerol levels, low density lipoprotein level and significantly reduced high density lipoproteins cholesterol levels when compared to the patients who experienced only chest pain (negative troponin) and healthy controls.
Conclusions:
Traditional lipid profile levels is still can be used in screening populations to identify the subjects with high risk of developing cardiac event in case if the laboratory set up has not troponin test facilities.

Serum lipids are fats and fatty substances in the blood and are crucial for various bodily functions, including energy storage, cellular structure, and hormone production. Serum lipids consist of cholesterol, triglycerides, and phospholipids.
Cholesterol is a soft, fat-like substance found in all body cells. It is crucial for producing hormones, vitamin D, and substances that aid...
