Treatment of Heart Failure
Heart failure occurs when the heart cannot pump enough blood to meet the body's needs. It is a chronic condition that causes fatigue, shortness of breath, and fluid retention (edema). It requires ongoing medical management.
Managing Heart Failure effectively requires a combination of medical treatment, lifestyle modification, and regular monitoring. With a structured management plan, most people with Heart Failure can maintain a good quality of life and prevent serious complications.
First-Line Treatment Principles
- ✓Risk factor modification: target BP <130/80 mmHg in most patients, LDL according to risk category
- ✓Antiplatelet therapy (aspirin or P2Y12 inhibitor) for established atherosclerotic disease
- ✓ACE inhibitor or ARB for heart failure with reduced ejection fraction (HFrEF) and post-MI LV dysfunction
- ✓Beta-blocker for rate control, post-MI, and stable HFrEF
- ✓Statin therapy for all patients with established ASCVD or high CV risk
What to Do Now
- Learn your personal risk factors for Heart Failure (family history, age, lifestyle)
- Attend regular health check-ups and screening tests appropriate for your age and risk
- Track new or changing symptoms, especially those associated with Heart Failure
- Use our AI symptom checker to assess whether your symptoms fit an early Heart Failure pattern
- Discuss preventive strategies and early monitoring with your GP
- Build a personalised management plan with your GP or specialist
- Adhere consistently to prescribed medications — do not stop without medical advice
- Adopt a Heart Failure-appropriate diet (anti-inflammatory, low-glycaemic, or disease-specific)
Medications Used in Heart Failure
Empagliflozin is an SGLT-2 inhibitor that lowers blood glucose by promoting urinary glucose excretion, with additional benefits for heart and kidney protection.
Dapagliflozin is an SGLT-2 inhibitor that lowers blood glucose by promoting urinary glucose excretion, with additional benefits for heart and kidney protection.
Canagliflozin is an SGLT-2 inhibitor that lowers blood glucose by promoting urinary glucose excretion, with additional benefits for heart and kidney protection.
Ertugliflozin is an SGLT-2 inhibitor that lowers blood glucose by promoting urinary glucose excretion, with additional benefits for heart and kidney protection.
Enalapril is an ACE inhibitor that lowers blood pressure, reduces cardiac workload, and provides kidney protection in hypertension, heart failure, and diabetic nephropathy.
Lisinopril is an ACE inhibitor that lowers blood pressure, reduces cardiac workload, and provides kidney protection in hypertension, heart failure, and diabetic nephropathy.
Ramipril is an ACE inhibitor that lowers blood pressure, reduces cardiac workload, and provides kidney protection in hypertension, heart failure, and diabetic nephropathy.
Perindopril is an ACE inhibitor that lowers blood pressure, reduces cardiac workload, and provides kidney protection in hypertension, heart failure, and diabetic nephropathy.
Non-Pharmacological Management
- •Cardiac rehabilitation program after MI, HF, or revascularisation
- •Dietary modification: Mediterranean or DASH diet; restrict sodium <2g/day in HF
- •Regular aerobic exercise: 150 min/week moderate intensity (when stable)
- •Smoking cessation — reduces CV event risk by 30–50% within 1 year
- •Weight management: target BMI 20–25 kg/m²
- •Alcohol restriction: ≤2 units/day men, ≤1 unit/day women
- •Stress reduction and sleep optimisation
Treatment Goals
Monitoring Parameters
- ◆BP and heart rate at every clinical visit
- ◆ECG: at baseline, after medication changes, and when symptomatic
- ◆Echocardiogram: for HF monitoring (EF, wall motion) — annually or after therapy change
- ◆Lipid panel: 4–12 weeks after statin initiation or dose change; then annually
- ◆Renal function and electrolytes (eGFR, K+): within 1–2 weeks of starting ACE inhibitor/ARB/diuretic
- ◆HbA1c if diabetic (target <7%); weight and fluid balance in HF
- ◆INR monitoring for warfarin therapy (target INR 2–3 for most indications)
Red Flags — When to Escalate
- ⚠Any of the characteristic symptoms of Heart Failure — even mild — in a high-risk individual
- ⚠Progressive worsening of early warning signs over weeks
- ⚠Laboratory abnormalities (e.g., blood sugar, inflammatory markers) without full symptoms
- ⚠Unexplained weight loss, night sweats, or fatigue persisting >2 weeks
- ⚠Strong family history of Heart Failure combined with new relevant symptoms
- ⚠Sudden worsening of Heart Failure symptoms despite established treatment
Escalation Criteria
- →Refractory angina despite maximal medical therapy → invasive assessment (coronary angiography)
- →Worsening HF despite GDMT → device therapy consideration (ICD, CRT) or specialist referral
- →Uncontrolled BP >180/110 on ≥3 agents → secondary hypertension workup
- →New or worsening arrhythmia → cardiology review
- →Acute coronary syndrome: activate emergency pathway immediately
