Heart failure is a chronic condition in which the heart cannot pump blood effectively enough to meet the body’s needs. When the heart becomes weakened or stiff, it cannot circulate blood efficiently, which may lead to a buildup of fluid in the lungs, legs, and other parts of the body. Despite its name, heart failure does not mean that the heart has stopped working. Instead, it means the heart is not functioning as well as it should.
Symptoms of heart failure can develop gradually and may worsen over time. Common signs include:
• Shortness of breath, especially during activity or when lying flat
• Fatigue and weakness
• Swelling in the legs, ankles, or feet
• Rapid or irregular heartbeat
• Persistent cough or wheezing
• Reduced ability to exercise or perform daily activities
Some individuals may also experience sudden weight gain due to fluid retention.
Heart failure can result from conditions that damage or weaken the heart muscle.
Common causes include:
• Coronary Artery Disease
• Heart Valve Disease
• Hypertension (high blood pressure)
• Arrhythmia
• Previous heart attack
• Cardiomyopathy (disease of the heart muscle)
Lifestyle factors such as smoking, obesity, and lack of physical activity may also increase the risk.
Healthcare professionals may diagnose heart failure through several evaluations, including:
• Medical history and physical examination
• Echocardiography (ultrasound of the heart)
• Electrocardiogram (ECG)
• Chest X-ray
• Blood tests
• Stress testing or cardiac imaging
These tests help determine how well the heart is functioning and guide treatment decisions.
You should consult a healthcare professional if you experience:
• Persistent shortness of breath
• Swelling in the legs or ankles
• Unusual fatigue or weakness
• Difficulty breathing when lying down
• Sudden weight gain or fluid retention
Early diagnosis and proper management can help control symptoms and improve long-term health outcomes.
