How you might notice it

01Shortness of breath with activity that worsens steadily over days to weeks; later, breathlessness occurs at rest and limits speech in long sentences.

02Orthopnea — breathlessness when lying flat, relieved by sitting up or sleeping on 2-3 pillows. A specific symptom that signals elevated left-sided filling pressures.

03Paroxysmal nocturnal dyspnea — waking 1-3 hours after falling asleep gasping for air, relieved by sitting upright and walking to a window.

04Bilateral lower-extremity swelling that develops over days, pits with finger pressure, and worsens by evening. Severe cases extend to the thighs, sacrum, or abdomen.

05Weight gain of 1-2 kg over 3-5 days from fluid retention; a single most useful self-monitoring metric in chronic heart failure.

06Fatigue and exercise intolerance disproportionate to age — the patient can no longer carry groceries or climb a single flight of stairs without resting.

07Persistent dry or wet cough, often worse at night, sometimes producing pink frothy sputum during acute pulmonary edema.

08Reduced appetite, nausea, and early satiety from gut congestion; over time this produces unintentional weight loss and cardiac cachexia.

09Palpitations and irregular pulse, often from atrial fibrillation, which complicates roughly 30-40% of heart failure.

10Mental status changes — fatigue, slowed thinking, sometimes frank confusion — in patients with low cardiac output or hyponatremia.

early warning signs

•Daily morning weight increase of more than 1.4 kg (3 lb) over 2 days or 2.3 kg (5 lb) over a week
•New-onset orthopnea — sleeping on an extra pillow for the first time
•Mild ankle swelling and tighter shoes by end of day in someone with hypertension or coronary disease
•A reduction in walking distance — fewer blocks before stopping to breathe — over the previous 1-2 weeks
•Elevated NT-proBNP on a routine blood draw in a high-risk adult, especially after hypertension or recent MI

● emergency signs

•Severe breathlessness at rest, inability to lie flat, pink frothy sputum — acute pulmonary edema, call emergency services
•Chest pain with breathlessness — possible acute coronary syndrome causing decompensation; treat as a STEMI/NSTEMI workup
•Heart rate >130/min with hypotension or cool clammy extremities — cardiogenic shock; needs ICU vasopressors and mechanical support
•Sudden palpitations with syncope or near-syncope — ventricular arrhythmia in a structurally diseased heart; emergency call
•Confusion, lethargy, or oliguria in a known heart-failure patient — low-output state; rapid escalation needed

diagnosis

Heart failure diagnosis is clinical, anchored by symptoms (Framingham major and minor criteria are still useful) and confirmed by objective testing. The workup begins with a focused history (effort tolerance, orthopnea, paroxysmal nocturnal dyspnea, recent weight change) and an examination for elevated jugular venous pressure, S3 gallop, displaced apical impulse, bibasilar crackles, hepatomegaly, and pitting edema. The single most useful blood test is BNP or NT-proBNP — a level below the rule-out threshold (NT-proBNP <125 pg/mL in chronic ambulatory, <300 pg/mL in acute presentation) makes heart failure unlikely; levels above the rule-in threshold support the diagnosis but are not specific. Twelve-lead ECG looks for prior MI, left ventricular hypertrophy, conduction disease, and arrhythmia; a completely normal ECG makes systolic HF less likely. The diagnostic linchpin is transthoracic echocardiogram, which yields left ventricular ejection fraction, chamber sizes, wall thickness, valvular function, and diastolic indices — and so determines whether the patient has HFrEF, HFmrEF, or HFpEF. Additional testing — coronary angiography or CT coronary angiography for suspected ischemic cause, cardiac MRI for suspected infiltrative disease, viability imaging before revascularization, right heart catheterization in selected cases — is targeted to the phenotype. Once heart failure is established, a search for the underlying cause is mandatory; reversible causes (tachycardia-mediated cardiomyopathy, alcoholic cardiomyopathy, peripartum cardiomyopathy, severe valve disease) change treatment trajectory.

Key tests

BNP or NT-proBNPExcludes heart failure when below age-adjusted thresholds and quantifies hemodynamic congestion when elevated. Tracks treatment response over time.

12-lead ECGIdentifies prior infarction, left ventricular hypertrophy, conduction delay (left bundle branch block raises CRT eligibility), and atrial fibrillation.

Transthoracic echocardiogramMeasures left ventricular ejection fraction, chamber dimensions, wall motion, diastolic function, valve disease, and pulmonary pressures. Single most important test for phenotyping.

Chest X-rayDetects pulmonary edema (cephalization, Kerley B lines, alveolar opacities), cardiomegaly, and pleural effusions; helps rule out non-cardiac dyspnea.

Cardiac MRIBest test for suspected myocarditis, infiltrative disease (cardiac amyloid, sarcoid), and assessment of viability before revascularization. Quantifies fibrosis with late gadolinium enhancement.

Coronary angiography or CT coronary angiographyConfirms or excludes ischemic etiology — required if revascularization could change management. CT is appropriate for low/intermediate pretest probability; invasive angiography for high probability.

Right heart catheterization (selected)Direct measurement of pulmonary artery pressures, wedge pressure, and cardiac output. Used to confirm pulmonary hypertension, guide advanced HF therapy decisions, and assess transplant candidacy.

Cardiopulmonary exercise testing (CPET, peak VO2)Quantifies functional capacity and prognosis; peak VO2 <14 mL/kg/min is a key threshold for transplant evaluation.

Outlook

Heart failure remains a high-mortality syndrome despite advances. Five-year all-cause mortality in clinically apparent HF is roughly 50% across most population studies, though stage and treatment intensity vary that figure substantially. Stage A and B carry the best outlook; stage D, defined by refractory symptoms despite optimized therapy, has 1-year mortality of 25-50% without advanced interventions. Quadruple guideline-directed medical therapy lowers 2-year all-cause mortality in HFrEF by 60-70% versus historical placebo, and STRONG-HF demonstrated that rapid up-titration within 6 weeks of an admission reduces 180-day death or readmission by 34%. HFpEF mortality is somewhat lower than HFrEF at any given age but rises sharply with comorbid burden (atrial fibrillation, CKD, diabetes). LVAD and transplantation extend median survival from 6-12 months untreated stage D to 5-10 years. Self-management — daily weights, low-sodium diet, vaccine uptake, structured exercise, early symptom reporting — and early specialty follow-up after discharge are independently associated with better outcomes.

Causes & risk factors

known causes

Coronary artery disease and prior myocardial infarction: Ischemic cardiomyopathy is the leading cause of HFrEF in high-income countries. Myocardial infarction destroys functioning muscle and triggers maladaptive remodeling. About two-thirds of HFrEF cases worldwide have an ischemic etiology.
Long-standing hypertension: Chronically elevated afterload produces left ventricular hypertrophy, diastolic stiffness, and ultimately systolic decline. Hypertension is the leading single risk factor for HFpEF and the second-leading for HFrEF after coronary disease.
Valvular heart disease: Severe aortic stenosis, aortic regurgitation, mitral regurgitation, and mitral stenosis all impose pressure or volume overload that culminates in heart failure. Valve surgery or transcatheter intervention can reverse the syndrome early in the course.
Cardiomyopathies (dilated, hypertrophic, restrictive): Genetic and acquired myocardial diseases produce systolic or diastolic dysfunction independent of coronary disease. Dilated cardiomyopathy is the most common HF cause in patients under 60; titin and lamin gene variants are increasingly identified.
Atrial fibrillation with rapid ventricular response: Sustained tachycardia (>110 bpm for weeks) causes tachycardia-induced cardiomyopathy in some patients. Rate or rhythm control can fully reverse HF in this subgroup.
Diabetes, obesity, and metabolic syndrome: Obesity and type 2 diabetes drive both HFrEF and especially HFpEF through microvascular disease, myocardial lipid accumulation, systemic inflammation, and AGE-mediated stiffening. They roughly double HF lifetime risk.
Cardiotoxic drugs and substances: Anthracycline chemotherapy (doxorubicin), trastuzumab, certain tyrosine kinase inhibitors, immune checkpoint inhibitors, methamphetamine, cocaine, and heavy chronic alcohol use cause cardiomyopathy. Risk is dose-related and often partially reversible if recognized early.
Myocarditis and infiltrative disease: Viral myocarditis (Coxsackie B, parvovirus, SARS-CoV-2), sarcoidosis, amyloidosis (especially ATTR in older men), and hemochromatosis can produce restrictive or dilated phenotypes. Cardiac MRI and targeted testing identify these.

risk factors

Hypertensionmodifiable: Each 20 mmHg rise in systolic pressure roughly doubles HF risk over time. Treating hypertension lowers HF incidence by 40-50%, the largest effect of any intervention.
Coronary artery disease and prior MImodifiable: A first MI carries a roughly 20-30% lifetime risk of clinical HF. Reperfusion within 90 minutes of presentation and post-MI guideline therapy substantially reduce that risk.
Type 2 diabetesmodifiable: Doubles HF risk independent of coronary disease. SGLT2 inhibitors reduce HF hospitalization by 25-35% in diabetes regardless of baseline HF status.
Obesity (BMI ≥30)modifiable: Each 5-unit BMI increase raises HF risk by about 20%. Obesity is the dominant driver of the rising HFpEF prevalence.
Older agenon-modifiable: Incidence doubles per decade after age 50; lifetime risk after age 40 is ~24%.
Male sex (for HFrEF) / female sex (for HFpEF)non-modifiable: Men predominate in HFrEF presentations; women predominate in HFpEF, especially in their 70s and 80s.

Living with Heart Failure

Timeline

After an acute decompensation, congestion typically resolves over 3-7 days of inpatient diuresis and oral therapy is initiated or up-titrated during the same admission. Most patients reach a new functional baseline within 4-6 weeks. With rapid quadruple-therapy titration over 6 weeks per STRONG-HF, EF improvement (in HFrEF) is often visible at 3-6 months; full myocardial reverse remodeling can continue for 12 months or more. Cardiac rehabilitation across 8-12 weeks measurably improves exercise tolerance and quality of life.

Lifestyle

01Weigh daily on the same scale at the same time and report a 1.4 kg gain over 2 days or 2.3 kg gain over a week.
02Restrict sodium to under 2 g per day during decompensation; under 3 g per day in stable chronic HF.
03Limit fluid intake to 1.5-2.0 L per day if hyponatremia or severe congestion is present; loose restriction in mild HF.
04Perform structured aerobic exercise 30-45 minutes most days, ideally through a cardiac rehabilitation program.
05Take an annual influenza vaccine and the recommended pneumococcal and COVID-19 vaccines.
06Avoid NSAIDs — they retain sodium and water, raise blood pressure, and trigger decompensation.
07Sleep with the head of the bed elevated 20-30° if orthopnea is present, and seek evaluation for sleep apnea.
08Stop tobacco use completely; nicotine raises afterload and accelerates coronary disease.

Daily management

01Weigh yourself first thing in the morning after voiding, in the same clothing, and log the number
02Take medications on schedule and use a pill organizer; record any new dose changes
03Restrict sodium and track approximate daily intake during weekly meal planning
04Note new orthopnea, increased breathlessness, or palpitations and report to your clinician promptly
05Schedule a heart-failure clinic visit within 7-14 days of any hospital discharge — early follow-up reduces readmission by 25-30%
06Maintain vaccinations and avoid contact with sick household members during respiratory virus season

Exercise

Aerobic exercise is recommended for nearly all stable HF patients. Begin with 5-10 minutes of low-intensity walking and build to 30-45 minutes of moderate-intensity aerobic exercise 3-5 times per week, supplemented by resistance training twice weekly. A formal cardiac rehabilitation program is the safest entry point and reduces HF readmission by roughly 25% per HF-ACTION subgroup data. Avoid maximal isometric exercise and prolonged Valsalva maneuvers in advanced HF.

Frequently asked

What is the life expectancy with heart failure?

Five-year all-cause mortality with clinically apparent heart failure is roughly 50%, but this varies dramatically by stage, ejection fraction, and treatment. Patients on guideline-directed quadruple therapy for HFrEF have substantially better survival than historical figures suggest, and selected stage D patients can receive transplant or LVAD that extends median survival to 5-10 years.

What is the difference between HFrEF and HFpEF?

HFrEF means heart failure with reduced ejection fraction (LVEF ≤40%) — a problem of systolic pump function. HFpEF means heart failure with preserved ejection fraction (LVEF ≥50%) — a problem of diastolic relaxation despite a normal-looking pump. Treatment differs: HFrEF responds to quadruple therapy with mortality benefit, while HFpEF mainly responds to SGLT2 inhibitors and aggressive comorbidity control.

What is congestive heart failure?

Congestive heart failure is an older term used when fluid backs up into the lungs, abdomen, or legs from a failing heart. Modern cardiology simply uses heart failure, with congestion described as a symptom. The signs are the same — breathlessness, swelling, weight gain, and reduced exercise tolerance.

What is ejection fraction?

Ejection fraction is the percentage of blood the left ventricle pumps out with each beat. A normal LVEF is 55-70%. LVEF 41-49% is mildly reduced (HFmrEF); LVEF 40% or below is reduced (HFrEF); LVEF 50% or above with HF symptoms is preserved (HFpEF). Echocardiogram is the standard way to measure it.

What causes heart failure?

The leading causes are coronary artery disease and prior heart attack, long-standing hypertension, valve disease, atrial fibrillation, cardiomyopathies, diabetes, obesity, and cardiotoxic drugs such as anthracycline chemotherapy. In many patients more than one cause is present.

What are the early signs of heart failure?

Early signs include new breathlessness when walking up stairs, new orthopnea (using extra pillows), ankle swelling that returns each evening, weight gain of more than 1.4 kg over two days, and reduced exercise tolerance. Persistent dry cough that is worse at night can also be an early manifestation.

Can heart failure be cured?

Heart failure is usually a chronic syndrome rather than a curable disease, but selected causes are fully reversible — tachycardia-mediated cardiomyopathy with rate control, alcoholic cardiomyopathy with abstinence, peripartum cardiomyopathy in many cases, and severe valve disease after surgical correction. For most patients with chronic HFrEF, optimized therapy improves ejection fraction and quality of life without permanent cure.

What is the four-drug therapy for heart failure?

Modern quadruple therapy for HFrEF combines an ARNI (sacubitril-valsartan) or ACE inhibitor or ARB, an evidence-based beta-blocker (carvedilol, metoprolol succinate, or bisoprolol), a mineralocorticoid receptor antagonist (spironolactone or eplerenone), and an SGLT2 inhibitor (dapagliflozin or empagliflozin). Started together and titrated rapidly, this regimen cuts mortality by roughly 70% compared with placebo.

Is heart failure the same as a heart attack?

No. A heart attack (myocardial infarction) is an acute event where a coronary artery blockage damages heart muscle. Heart failure is a chronic syndrome where the heart cannot pump effectively. A heart attack can cause heart failure by destroying muscle, but they are distinct diagnoses with different treatments.

Can young people get heart failure?

Yes. Young adults can develop heart failure from genetic cardiomyopathies (dilated, hypertrophic), myocarditis after viral infection, peripartum cardiomyopathy in pregnancy, congenital heart disease, anthracycline chemotherapy in childhood cancer survivors, and stimulant or alcohol use. Genetic testing and cardiac MRI are increasingly important in this age group.

How much salt can I have with heart failure?

Most guidelines recommend keeping sodium under 2-3 grams per day for chronic heart failure, dropping to under 2 grams during decompensation. Processed and restaurant foods are usually the biggest sources. Read labels for sodium content rather than just avoiding the salt shaker.

Can I exercise with heart failure?

Yes, and most patients should. Structured aerobic exercise — 30-45 minutes most days at moderate intensity — improves quality of life, exercise tolerance, and reduces readmissions by roughly 25% in cardiac rehabilitation programs. Start in a supervised program if you have had a recent hospitalization or advanced disease.

What is BNP and what does it mean?

BNP (B-type natriuretic peptide) and NT-proBNP are hormones released by stretched cardiac muscle. Levels rise in heart failure and fall with successful treatment. NT-proBNP below 125 pg/mL in chronic ambulatory patients makes heart failure unlikely; markedly elevated levels support the diagnosis and indicate higher risk.

Why is daily weight important in heart failure?

Sudden weight gain reflects fluid retention before breathlessness or swelling become severe. A gain of 1.4 kg over two days or 2.3 kg over a week should prompt a call to the heart-failure clinic for diuretic adjustment, often preventing hospitalization. Weigh yourself the same time each morning after voiding.

Should I have an ICD for heart failure?

An implantable cardioverter-defibrillator is recommended for primary prevention in HFrEF with ejection fraction at or below 35% on optimized medical therapy for at least 3 months and an expected survival of more than one year. It is recommended for secondary prevention after sustained ventricular tachycardia or fibrillation. Your cardiologist will weigh benefit against age and comorbidities.

Can I drink alcohol with heart failure?

Avoid alcohol entirely if you have alcohol-related or any cause cardiomyopathy. Other patients may have one drink daily for women or two for men, but no more — alcohol triggers arrhythmias and raises blood pressure. Discuss specific recommendations with your cardiologist based on your cause and severity.

What is cardiac resynchronization therapy (CRT)?

CRT is a pacemaker with leads in both ventricles that resynchronizes contraction in patients with a wide QRS, especially left bundle branch block. It is recommended for symptomatic HFrEF with ejection fraction at or below 35% and QRS at or above 150 ms (or 130-149 ms with LBBB). It reduces hospitalization and mortality by about 30%.

What is a heart transplant evaluation?

Heart transplant evaluation is a multi-day workup of stage D heart failure patients who have failed optimal medical and device therapy. It includes cardiopulmonary exercise testing (peak VO2 below 14 mL/kg/min is a key threshold), right heart catheterization, cancer screening, and psychosocial assessment. Selected candidates are listed for donor matching.

Can heart failure affect the kidneys?

Yes. Cardiorenal syndrome describes the bidirectional relationship in which heart failure worsens kidney function and chronic kidney disease worsens heart failure. SGLT2 inhibitors benefit both organs simultaneously and are now recommended at any eGFR above 20 in HFrEF.

Are SGLT2 inhibitors safe if I do not have diabetes?

Yes. Dapagliflozin and empagliflozin reduce hospitalization and mortality in heart failure regardless of diabetes status. Side effects include occasional genital yeast infections and rare diabetic ketoacidosis in diabetics. The cardiovascular benefit is independent of glucose-lowering.

What is the difference between left and right heart failure?

Left-sided failure backs blood up into the lungs, causing breathlessness, orthopnea, and pulmonary edema. Right-sided failure backs blood up into the body, causing leg swelling, hepatic congestion, and ascites. The two often coexist because left heart failure is the leading cause of right heart failure.
