Heart Failure Life Expectancy Calculator
Understand statistical survival estimates for heart failure by entering age, NYHA functional class, and ejection fraction category. Results reflect population-level medians from published cohort studies — for educational reference only.

How does this calculator work?
Heart failure median survival ranges from roughly 9 years (NYHA I, younger patients) to under 1 year (NYHA IV, elderly). NYHA functional class is the strongest simple predictor; ejection fraction and age also matter. Modern guideline therapies improve outcomes substantially. These are population medians from CHARM / Cowie 2000 cohorts — always consult a cardiologist for individual prognosis.
Formula
How this is calculated
Heart failure (HF) prognosis has improved significantly over the past 30 years with angiotensin blockers, beta-blockers, mineralocorticoid antagonists, SGLT2 inhibitors, and device therapies, but it remains a serious condition. The New York Heart Association (NYHA) functional classification — ranging from Class I (no symptoms at rest or ordinary activity) to Class IV (symptoms at rest) — is one of the strongest independent predictors of outcome in clinical studies.
This calculator applies NYHA-class survival medians derived from the CHARM clinical programme and community-based cohorts (Cowie et al. 2000 Hillingdon study; Roger et al. Olmsted County data), with an age adjustment that reflects younger patients' substantially better prognosis, and a small ejection-fraction adjustment: patients with preserved EF (HFpEF, ≥50%) have broadly similar overall mortality to HFrEF at the population level in modern cohorts, while mildly reduced EF (40–49%) occupies an intermediate position per Shah et al. 2017.
Important caveats: the estimates here are unadjusted for comorbidities (diabetes, CKD, atrial fibrillation), whether the patient receives guideline-directed therapy (which can extend survival by several years), device therapy (ICD, CRT), or the specific aetiology of HF. They reflect outcomes averaged over populations that span the pre-SGLT2 era. Individual prognosis should always be assessed by a cardiologist.
Frequently asked questions
Median survival from diagnosis varies widely: NYHA Class I–II patients often live 5–10 years or more, while Class III–IV patients may have a median survival of 1–3 years without aggressive intervention. Modern therapies including SGLT2 inhibitors and cardiac resynchronisation therapy have meaningfully improved these numbers since 2020.
NYHA classification describes how much a patient's symptoms limit physical activity: Class I is no limitation; Class II is slight limitation with ordinary activity; Class III is marked limitation; Class IV is symptoms at rest. It is the most widely used functional measure in HF clinical trials and is one of the strongest predictors of short-term mortality.
Both carry serious mortality risk. HFpEF has similar all-cause mortality to HFrEF, though HFrEF responds more reliably to established therapies (ACE inhibitors, beta-blockers, MRAs). HFpEF management has fewer proven disease-modifying treatments, though SGLT2 inhibitors now show benefit in both phenotypes.
