HF disease, or heart failure, is a condition where the heart can't pump enough blood to meet the body's needs. This means the heart muscle isn't pumping blood as effectively as it should. Sometimes, it's also called congestive heart failure, although this term isn't always used interchangeably.
Understanding Heart Failure
Heart failure is a chronic and progressive condition. This means it worsens over time. The inability of the heart to pump efficiently often leads to a backup of blood, causing fluid to build up in various parts of the body. This fluid buildup is a key characteristic of heart failure.
Several factors contribute to heart failure, including:
- Weakened heart muscle: The heart muscle may become weakened due to various conditions like high blood pressure, coronary artery disease, or previous heart attacks.
- High blood pressure: Persistently high blood pressure forces the heart to work harder, eventually weakening it.
- Valve problems: Damaged heart valves can impede blood flow, hindering the heart's ability to pump efficiently.
- Heart rhythm abnormalities: Irregular heartbeats can disrupt the heart's pumping rhythm.
The symptoms of heart failure vary, but some common ones include:
- Shortness of breath
- Fatigue
- Swelling in the legs, ankles, and feet
- Persistent cough
- Rapid heart rate
Heart failure is classified into different stages (A, B, C, and D) based on severity, and treatments vary depending on the stage and underlying causes. These treatments aim to manage symptoms, slow the progression of the disease, and improve the patient's quality of life. These may include medications, lifestyle changes, and in some cases, surgery or other medical interventions.
