🫀 Heart Failure Symptoms Explained
Heart failure does not mean the heart has stopped beating.
It means the heart is no longer pumping efficiently enough to meet the body’s demands.
Symptoms depend on which side of the heart is affected — and recognizing them early can make a significant difference in patient outcomes.
🔴 Left-Sided Heart Failure (Lungs)
Blood backs up into the lungs, leading to:
• Shortness of breath
• Orthopnea (difficulty lying flat)
• Paroxysmal nocturnal dyspnea
• Persistent cough (may be pink/frothy)
• Crackles on auscultation
Think: Left = Lungs
🔵 Right-Sided Heart Failure (Systemic circulation)
Blood backs up into the body, causing:
• Peripheral edema
• Abdominal bloating/ascites
• Jugular venous distension
• Weight gain from fluid retention
• Reduced appetite
Think: Right = Rest of the body
⚠️ General Symptoms (Both Types)
• Fatigue and weakness
• Reduced exercise tolerance
• Tachycardia
• Nocturia
• Confusion (especially in elderly patients)
🚨 Seek urgent care if there is:
• Sudden severe breathlessness
• Chest pain
• Rapid weight gain
• Pink frothy sputum
Early identification = early intervention.
