Heart failure:
can it be cured? Prognosis and how long you can live

Article written and reviewed by Dr Luca Moretti

Heart failure does not have the same prognosis for everyone. Some people remain stable for many years with a good quality of life; others have a more aggressive disease, repeated hospitalizations, or a cause that is difficult to correct. In some forms, cardiac function can improve markedly, but this does not necessarily mean that the disease has permanently disappeared.
For this reason, a question such as "how long can you live with heart failure?" cannot be answered correctly with a single number for an individual patient.

The 2026 ESC guidelines note that, despite major therapeutic advances, at the population level five-year survival after a diagnosis of heart failure remains below 60%. This statistic, however, includes people with very different ages, disease severity, causes, and treatments and is not a personal prediction.

Can heart failure be cured?

Heart failure is a syndrome, not a single disease. The possibility of recovery therefore depends on the cause. Dysfunction caused by persistent tachycardia, myocarditis, correctable valvular heart disease, alcohol-related cardiomyopathy, or other reversible conditions can improve greatly when the underlying problem is treated.
Even in heart failure with reduced ejection fraction, modern therapy can lead to favorable remodeling, reduced symptoms, and an increase in ejection fraction.

When ventricular function improves, this is referred to as heart failure with improved ejection fraction. It is a prognostically more favorable condition than persistent marked systolic dysfunction, but it is often more appropriate to speak of remission rather than permanent cure.
In the long-term follow-up of the TRED-HF study, patients with apparently recovered dilated cardiomyopathy showed a substantial risk of relapse after treatment reduction or withdrawal.

Why there is no life expectancy that applies to everyone

Survival statistics reported in studies describe groups of patients and vary greatly according to who is included. A person diagnosed as an outpatient and clinically stable does not have the same risk as someone who has just been hospitalized for acute decompensation of chronic heart failure. Mean age, comorbidities, and the period in which the study was conducted also influence the results.
A meta-analysis of community studies published in 2019 showed average five-year survival of around 57%, but it included very different therapeutic eras and considerable heterogeneity among populations.

Today, many patients receive treatments that were not available in older cohorts, including ARNIs and SGLT2 inhibitors, in addition to more systematic use of mineralocorticoid receptor antagonists and devices in appropriate patients. For this reason, using an old percentage as though it precisely described the outlook of a person treated in 2026 would be incorrect.

Which factors have the greatest influence on prognosis

Prognosis depends on a combination of factors. Age, the cause of heart failure, symptom severity, functional capacity, previous hospitalizations, blood pressure, kidney function, sodium, natriuretic peptides, anemia or iron deficiency, heart rhythm, and comorbidities such as diabetes and lung disease all matter.
The presence of persistent congestion or signs of reduced perfusion also identifies a more delicate clinical situation.

Ejection fraction is important but is not a "life counter." Some patients with a very low EF can remain stable for a long time with effective treatment, whereas patients with preserved EF can have important symptoms, hospitalizations, and risk related to age and comorbidities.
For this reason, cardiologists integrate multiple pieces of information and, in appropriate cases, use validated prognostic scores rather than relying on a single echocardiographic measurement.

How much does a hospitalization for heart failure matter?

A hospitalization for decompensation is an important event in the course of the disease because it identifies a period of greater instability. European registries have shown that patients hospitalized for acute heart failure have higher subsequent mortality than outpatients with stable chronic heart failure.
This does not mean that the deterioration is irreversible: hospitalization is also an opportunity to correct congestion, identify the precipitating factor, and rapidly optimize treatment.

The 2026 ESC guidelines recommend an intensive strategy after hospitalization, with initiation and titration of foundational therapy and close follow-up during the first few weeks. Reducing the risk of further decompensations is one of the central goals of treatment because repeated hospitalizations can accompany progression toward more severe forms.

What can concretely improve the outlook

The prognosis of heart failure is not determined once and for all at the time of diagnosis. Treating the cause, correctly taking heart failure medications, controlling blood pressure and diabetes, correcting iron deficiency when indicated, engaging in appropriate physical activity, and addressing arrhythmias, ischemia, or valvular heart disease can modify the course of the disease.
In selected patients, an implantable defibrillator and cardiac resynchronization therapy can reduce the risk of sudden death and heart failure events, respectively.

When severe symptoms, frequent hospitalizations, hypoperfusion, or dependence on advanced therapies persist despite optimized treatment, advanced heart failure may be present. In these cases, evaluation at a dedicated center allows timely consideration of ventricular assist devices, transplantation, or integrated palliative care according to the patient's characteristics and goals.

Frequently asked questions about prognosis and recovery

Can heart failure be cured?
It depends on the cause. Some forms can improve greatly or go into remission after treatment of the cause and heart failure therapy. In many patients, however, it remains a chronic condition requiring follow-up and treatment even when symptoms and ejection fraction improve.

How long can you live with heart failure?
There is no duration that applies to everyone. Population statistics describe very different groups and cannot predict an individual patient's survival. Age, cause, severity, hospitalizations, kidney function, comorbidities, and response to treatment profoundly affect prognosis.

Does a low ejection fraction alone determine life expectancy?
No. Ejection fraction is important but is not enough on its own. Symptoms, hospitalizations, kidney function, blood pressure, natriuretic peptides, heart rhythm, the cause of heart failure, and response to treatment are equally relevant.

If ejection fraction returns to normal, is heart failure cured?
Not necessarily. Improvement in ejection fraction is favorable, but it may represent remission and the risk of relapse may persist. The 2026 ESC guidelines generally recommend continuing foundational therapy at tolerated doses.

Does hospitalization for heart failure worsen prognosis?
A hospitalization for decompensation generally identifies a period of higher risk and makes it particularly important to optimize treatment, follow-up, and the search for factors that caused the deterioration.
