Cardiac Index Calculator
Calculate cardiac index, cardiac output, and stroke volume index from heart rate, stroke volume, and body surface area. Classifies hemodynamic status.
Heart Failure Life Expectancy Calculator
Review heart-failure prognosis context using NYHA class, ejection fraction, comorbidities, natriuretic-peptide level, and device status in an educational worksheet.
⚠️ Reference Note: This page is an educational heart-failure context worksheet, not a validated survival model or individualized life-expectancy tool. It does not reproduce SHFM, MAGGIC, transplant selection tools, or LVAD referral criteria.

| NYHA Class | General Symptom Burden | Worksheet Context |
|---|---|---|
| Class 1 | No limitation | Lower symptom burden on this worksheet |
| Class 2 | Slight limitation | Mild-to-moderate limitation context |
| Class 3 | Marked limitation | Higher symptom-burden context |
| Class 4 | Symptoms at rest | Highest symptom-burden context |
| Context Factor | Broad Direction | Comment |
|---|---|---|
| Low EF | Can signal greater disease burden | This page only groups EF into broad ranges; it does not model phenotype-specific outcomes. |
| Higher NYHA class | Often signals more symptom burden | Functional limitation is one of the clearest broad context clues on this worksheet. |
| Elevated BNP / NT-proBNP | Can reflect higher hemodynamic stress | Interpret the biomarker with kidney function, obesity, rhythm, and treatment context in mind. |
| CKD / diabetes | May complicate overall prognosis | The worksheet treats these as broad comorbidity markers rather than as a validated risk score input. |
| Device therapy | Can change outlook in selected patients | The page only notes device context; it does not estimate individualized device benefit. |

About the Heart Failure Life Expectancy Calculator
This page provides a simplified educational heart-failure prognosis worksheet using several common context factors such as NYHA class, ejection fraction, age, natriuretic peptide level, comorbidities, and device therapy. It is meant to show how overall context can change as those factors change.
The page is not a validated survival model. It does not reproduce the Seattle Heart Failure Model, MAGGIC, or any transplant/LVAD selection score, and it should not be treated as a precise forecast for an individual patient.
Use it only as a discussion aid and keep real prognostic decisions anchored in clinician assessment, named models, and heart-failure specialist review.
When This Page Helps
A simplified estimate can help explain why worsening symptoms, low EF, recurrent admissions, CKD, or elevated natriuretic peptides often trigger closer specialist review.
Its value is educational. It should not replace SHFM, MAGGIC, or clinician-led prognosis review.
How to Use the Inputs
- Enter age, NYHA class, and ejection fraction.
- Select device status and add major comorbidities.
- Add major comorbidities and a BNP or NT-proBNP value if available.
- Read the result as prognosis context, not as a validated prediction.
- Use clinician review and named models for real prognostic counseling or advanced-therapy decisions.
Formula used
Simplified educational risk layering:
Broad prognosis context from:
Factors include:
- EF adjustment
- Age adjustment
- Diabetes and CKD
- BNP / NT-proBNP range
- Device context
This page intentionally stops at worksheet context and does not generate a validated individualized survival percentage or median-survival forecast.Example Calculation
Result: Higher symptom-burden context with reduced EF and elevated natriuretic-peptide context
This profile shows several broad adverse context flags on the worksheet. The page is showing prognosis context only and does not replace a validated model or clinician-led interpretation.
Tips & Best Practices
- Treat the worksheet as educational context rather than as a survival prediction.
- Do not use the page to make transplant, LVAD, ICD, or hospice decisions.
- The same score can mean different things depending on therapy optimization and disease subtype.
- BNP, EF, and NYHA class all need clinical context.
- For serious prognostic counseling, use validated models and specialist review.
- The page is best used to support explanation, not to replace it.
What This Page Is
This page is a simplified educational worksheet that shows how broad prognostic factors can change heart-failure context.
What It Is Not
It is not a validated survival model, not a transplant or LVAD triage tool, and not a substitute for SHFM, MAGGIC, or clinician-led prognosis review.
Best Use
Use it to support a broad educational discussion about why symptom burden, EF, natriuretic peptides, comorbidities, and device therapy matter, while keeping real prognostic decisions anchored in validated models and specialist care.

Methodology
This page is a site-defined heart-failure context worksheet. It groups symptom burden, EF range, natriuretic-peptide context, device status, and a few comorbidity markers into broad educational context flags instead of calculating a validated survival percentage.
It is intentionally not a reproduction of SHFM, MAGGIC, or an advanced-therapy referral model. The purpose is explanation and context only, while real prognosis work stays anchored in validated models, clinician review, and current heart-failure guidelines.

Frequently Asked Questions
Individual predictions have substantial uncertainty. Even validated models are only estimates, and this page is simpler than those models, so it should be treated as context rather than as a direct prediction.
Yes. Guideline-directed therapy, device optimization, revascularization, arrhythmia control, and successful treatment of reversible contributors can all improve trajectory.
Those decisions require specialist evaluation and are not something this page can determine. Advanced-heart-failure referral usually depends on symptoms, admissions, objective exercise data, hemodynamics, and response to therapy.
The trajectory can differ, and preserved EF does not automatically mean low risk. This page is a broad educational estimator and does not model every phenotype accurately.
Both matter clinically, but this page only uses broad BNP ranges as a rough context signal. Real interpretation depends on obesity, kidney function, rhythm, and the overall clinical picture.
No. It is not a validated end-of-life or treatment-limitation tool.
