Frequently Asked Questions
Can I be tested to see if I have heart failure, or how serious my condition is?
Doctors confirm or grade heart-failure severity with a physical exam plus objective tests such as bloodwork (BNP/NT-proBNP), electrocardiography (ECG), chest X-ray, echocardiography, cardiac MRI, and sometimes stress testing or heart-catheterization. Results are interpreted against the NYHA functional classes (I–IV) or ACC/AHA stages (A–D) to show how advanced the condition is.
What caused my heart failure (or what are my risks of developing heart failure)?
Common causes include long-standing high blood pressure, coronary artery disease or prior heart attack, valve disease, diabetes, obesity, viral myocarditis, alcohol or drug toxicity, congenital defects, and certain chemotherapies or inherited cardiomyopathies. Your personal risk profile comes from a mix of these factors plus age, sex, family history, and lifestyle habits.
What can I do to prevent or control the progression of heart failure?
Control blood pressure, cholesterol, and diabetes, stop smoking, limit alcohol, follow a low-sodium/heart-healthy diet, stay physically active within your limits, maintain a healthy weight, take all prescribed medicines as directed, and attend regular follow-up visits. Rapidly reporting weight gain or new swelling helps clinicians adjust therapy before symptoms worsen.
Do I have systolic or diastolic heart failure, or both?
Systolic failure (HFrEF) means the left ventricle cannot contract effectively; diastolic failure (HFpEF) means it cannot relax and fill properly. An echocardiogram, MRI, or nuclear scan shows which form—or a mixture—you have, guiding drug and device choices.
What are the symptoms that should be reported to my doctor?
Sudden weight gain (≥2 kg/4–5 lb in 2 days), worsening shortness of breath (especially at rest or overnight), ankle or abdominal swelling, fainting or near-fainting, fast or irregular heartbeat, persistent cough with frothy sputum, extreme fatigue, or chest pain all warrant a call.
How often should I be examined by my doctor?
Stable patients are usually seen every 3–6 months. You’ll need sooner review after any medication change, device implantation, hospitalization, or if new symptoms appear. High-risk or recently decompensated patients may be monitored weekly until stable.
Is the pumping ability of my heart weakened?
Your imaging report will note “left-ventricular systolic function.” Terms like “mildly,” “moderately,” or “severely reduced” indicate how much contraction strength (ejection fraction) has fallen.
Has a test been performed to measure my ejection fraction?
Most patients have an echocardiogram, cardiac MRI, or nuclear MUGA scan that quantifies ejection fraction (EF). Ask for the date and result.
What is my ejection fraction?
Normal EF is roughly 50 %–70 %. HFrEF is <40>
40>
Am I at risk for an abnormal heart rhythm?
Heart-failure patients often develop atrial fibrillation or dangerous ventricular arrhythmias because diseased muscle disrupts electrical pathways. Risk rises when EF is <35>

(If you have an abnormal heart rhythm) What tests should I have to determine the cause of my abnormal heart rhythm and whether it is life-threatening?
Tests may include a 24- to 48-hour Holter monitor, multi-day patch recorder, implantable loop recorder, exercise treadmill, electrophysiology (EP) study, cardiac MRI for scar mapping, thyroid labs, and medication/toxin review. Results tell whether the rhythm warrants drug therapy, ablation, or an ICD.
What other medical conditions might affect heart failure?
Uncontrolled hypertension, sleep apnea, COPD, kidney disease, thyroid imbalance, anemia, diabetes, obesity, depression, and infections all worsen heart-failure control and should be treated aggressively.
What lifestyle changes will improve my symptoms?
Daily weight checks, 1.5–2 L fluid and 2 g sodium limits (unless instructed otherwise), graded exercise, up-to-date vaccinations, alcohol moderation, smoke-free living, good sleep hygiene, and stress-reduction techniques such as mindfulness or cardiac-rehab counseling measurably improve quality of life.
Will my heart failure get worse? Can I be cured?
Progression is common but not inevitable. Early diagnosis, optimal medical therapy, lifestyle changes, and timely device or surgical interventions can stabilize or even reverse remodeling in many patients. A true “cure” is rare unless the underlying cause is corrected (e.g., valve surgery, transplant).
How can I improve my quality of life and live longer?
Combine guideline-directed medical therapy (GDMT) with cardiac rehab, vaccinations, psychosocial support, strict dietary/fluid control, prompt reporting of symptom changes, and adherence to follow-ups. Consider palliative-care input early for symptom relief and goal-setting.
Can exercise and cardiac rehabilitation help me?
Yes. Supervised cardiac rehab improves functional capacity, reduces hospitalizations, and boosts mood. After rehab, a tailored home-exercise program (usually walking or stationary cycling) is safe for most stable patients.
What medical or surgical treatments are available for me?
Medications (ACE inhibitors/ARNIs, beta-blockers, MRAs, SGLT2 inhibitors, diuretics, ivabradine, iron therapy), implantable devices (ICD, CRT-pacemaker/defibrillator), catheter ablation, transcatheter or surgical valve repair, ventricular-assist devices, and ultimately transplantation are individualized options.
Am I at risk for ventricular fibrillation (VF) and sudden cardiac arrest?
Low EF (<35>
35>
Am I a candidate for an implanted cardioverter defibrillator (ICD) to reduce my risk of cardiac arrest?
ICDs are recommended for most patients with EF ≤35 % after ≥3 months of optimized medical therapy, or for those who have survived a prior cardiac arrest or sustained ventricular tachycardia. An EP specialist determines exact candidacy.
Will I benefit from a pacemaker?
A pacemaker treats bradycardia (slow heart rate) or helps resynchronize pumping in specific conduction disorders. If you experience symptomatic pauses, complete heart block, or have criteria for cardiac-resynchronization therapy (CRT), a pacemaker or CRT-device may help.
Can I be treated with medications?
Medications are the foundation of heart-failure management. Combinations of ACE-I/ARNI, beta-blocker, MRA, and SGLT2 inhibitor lower mortality and hospitalization risk. Diuretics relieve congestion; digoxin, hydralazine/isordil, or ivabradine are added in selected cases.
Is resynchronization therapy the right treatment for me?
CRT is advised when EF ≤35 %, NYHA class II–IV symptoms persist despite GDMT, and your ECG shows a wide QRS (≥130 ms) with left-bundle-branch block or significant dyssynchrony. It coordinates ventricular contractions and can raise EF and quality of life.
Am I a candidate for surgery? A heart transplant?
Valve repair/replacement, coronary bypass, or ventricular-assist devices (LVAD) may be options when medications no longer control symptoms. Transplant evaluation is considered for end-stage patients (NYHA III–IV) with refractory symptoms despite maximal therapy and no contraindications.
What clinical trials are under way to study heart failure patients?
Trials test new drugs (e.g., myosin activators, anti-fibrotic agents), novel devices (pulmonary-pressure sensors, gene therapy), and advanced imaging or digital-health tools. Your center’s research coordinator or ClinicalTrials.gov lists active studies.
Am I a candidate for a clinical trial?
Eligibility depends on your diagnosis, EF, kidney function, medications, and willingness to follow protocol visits. Trials can offer early access to promising therapies but require informed consent and rigorous follow-up.
Should I be evaluated by an electrophysiologist (a specialist in heart rhythm disorders)?
Yes, if you have documented or suspected arrhythmias, EF ≤40 %, syncope of unknown origin, consideration for ICD/CRT, or need ablation. An EP consultation refines diagnosis and tailors rhythm-specific treatments.
