Heart disease and heart failure are related but distinct conditions. Heart disease refers to a range of conditions affecting the heart's structure and function, including coronary artery disease, heart rhythm disorders, and valve problems. Conversely, heart failure occurs when the heart cannot pump blood effectively, leading to symptoms like fatigue, shortness of breath, and swelling in the legs. While heart disease can be a cause of heart failure, not all heart disease leads to heart failure. Understanding the differences between these conditions is crucial for effective management and treatment. If you have concerns about your heart, consult your GP for tailored advice and treatment options.
