Coronary Heart Disease Index Calculator

Tool Introduction

The Coronary Heart Disease Index Calculator is a convenient online tool designed to help users initially assess their risk of coronary heart disease based on their low-density lipoprotein (LDL) and high-density lipoprotein (HDL) levels. By entering simple blood lipid data, you can quickly understand your cardiovascular health status and use it as a reference for daily health management. This tool supports LDL and HDL input in mmol/L units and outputs the coronary heart disease risk index, current status, and standard range, helping you to pay timely attention to your health.

Significance of Coronary Heart Disease Index

Coronary heart disease, fully known as coronary atherosclerotic heart disease, is a common cardiovascular disease that seriously threatens human health. Dyslipidemia is one of its important risk factors. Among them, low-density lipoprotein (LDL) is often called "bad cholesterol," and excessively high levels increase the risk of atherosclerosis; high-density lipoprotein (HDL) is called "good cholesterol," which helps remove cholesterol from artery walls and has a protective effect. The coronary heart disease index calculated by this tool is usually derived from the ratio of LDL to HDL or other relevant formulas, used to comprehensively assess the relative impact of these two blood lipids on cardiovascular health. By paying attention to this index, users can better understand the relationship between blood lipid levels and the risk of coronary heart disease, thereby taking active intervention measures.

How to Use

1. In the "Low-density lipoprotein (LDL)" input box, enter your LDL blood lipid test value, in mmol/L. The input value must be between 0.1 and 10.
2. In the "High-density lipoprotein (HDL)" input box, enter your HDL blood lipid test value, in mmol/L. The input value must be between 0.1 and 5.
3. Ensure that the input values are within the valid range and use the correct units.
4. After completing the input, the system will automatically display the coronary heart disease risk index, current status, and standard range, or after you click the calculate button.

Frequently Asked Questions

• Q: What input formats are supported?
• A: This tool supports numerical (integer or decimal) input, with units in mmol/L. The valid range for low-density lipoprotein (LDL) is 0.1 to 10 mmol/L, and for high-density lipoprotein (HDL) is 0.1 to 5 mmol/L.
• Q: What is the format of the output results?
• A: The output results are displayed in a list format, including "Coronary Heart Disease Risk Index," "Status" (with color coding, e.g., "Normal" is green, "Suspected Coronary Heart Disease" is orange), and "Standard Range."
• Q: Can this index completely diagnose coronary heart disease?
• A: No. This tool provides preliminary risk assessment results, aiming to help users understand their risk trends. The diagnosis of coronary heart disease requires a combination of various clinical examinations, medical history, symptoms, and the judgment of a professional doctor. Please do not use the results of this tool as the sole basis for diagnosis.
• Q: If my blood lipid report unit is mg/dL, how do I convert it?
• A: If your blood lipid report unit is mg/dL, you need to convert it to mmol/L. The usual conversion formula is: mmol/L = mg/dL ÷ 38.67. Please be sure to complete the unit conversion before inputting.

Notes

• Data Accuracy: Please be sure to enter your latest and most accurate blood lipid test data to obtain reliable assessment results. Incorrect or outdated data will lead to inaccurate results.
• Unit Consistency: Input values must use mmol/L as the unit. If your blood lipid report unit is mg/dL, please be sure to convert it using the method described in the frequently asked questions above.
• Medical Consultation: The results of this tool are for reference only and do not constitute medical advice. For any health problems, disease diagnosis, or treatment plans, please be sure to consult a professional doctor or medical institution.
• Lifestyle: Maintaining a healthy lifestyle (including balanced diet, regular exercise, weight control, quitting smoking and limiting alcohol, etc.) is key to maintaining good blood lipid levels and preventing coronary heart disease. Assessment results should be understood in conjunction with your overall health status and lifestyle habits.
