Heart and vascular calculations often combine several measurements that are easy to misread in isolation. Heart Failure Life Expectancy Calculator keeps those inputs together and shows the result the implemented model is designed to produce.

What this calculator does

Heart Failure Life Expectancy Calculator uses Sex, Age, Height, Weight, Creatinine, Ejection fraction, Systolic blood pressure, and the remaining fields shown to calculate the plugin’s approximate 1-year heart-failure survival estimate. It is built around the exact fields displayed in this plugin rather than a generic version of the topic. Where supported, it also shows Model score and BMI so the primary result is easier to place in context. Cardiovascular formulas are sensitive to measurement technique and clinical context. A mathematically correct output can still be misleading if the input was obtained under a different physiologic condition, with a different assay, or outside the population for which the score was developed.

How to use it

Complete the requested fields, including Sex, Age, Height, Weight, Creatinine, and Ejection fraction, then finish the remaining items shown in the calculator. Confirm that each yes/no, category, date, or score option is applied exactly as labeled. When the formula combines measurements, use values obtained under the same assessment or physiologic conditions whenever possible.

How the calculation works

This implementation creates an internal heart-failure risk score from age, sex, ejection fraction, systolic pressure, creatinine, NYHA class, diabetes, COPD, smoking, heart-failure duration, beta-blocker use, and ACE inhibitor/ARB use. It then maps that score through a logistic curve to an approximate 1-year survival percentage. BMI is calculated from height and weight and displayed, but this build does not claim exact MAGGIC table calibration.

Example

Using the sample values prefilled in this calculator, the primary result is 92.41 % (Approximate 1-year survival), Model score is 8, and BMI is 24.5. This worked example shows how the plugin’s own default inputs flow through the implemented method; replace them with the correct patient, laboratory, imaging, or personal values before interpreting a result.

How to interpret the result

Read the output as approximate 1-year survival generated by this specific formula or score. The number is most useful when compared with the clinical context and, when appropriate, serial measurements or the current guideline pathway for the condition. A boundary value should not be overinterpreted as a sudden change in physiology.

Limitations and notes

The survival percentage is an approximation generated by this plugin’s simplified score-to-logistic mapping, not a fully validated individual prognosis or exact proprietary/reference MAGGIC calibration. Heart-failure outcomes change with phenotype, current therapies, devices, kidney function, biomarkers, and repeated clinical assessment.
