Congestive heart failure (CHF) is a condition that occurs when the heart is unable to pump enough blood to the body’s organs and tissues. This can occur when the heart is weakened by disease, injury, or a congenital defect. As a result, the heart is unable to deliver enough oxygen-rich blood to the body, leading to a buildup of fluid in the lungs, abdomen, and other organs.
CHF can be caused by a variety of factors, including coronary artery disease, high blood pressure, diabetes, and valve problems. It can also be caused by genetics, lifestyle factors, or the use of certain drugs. Treatment for CHF typically involves lifestyle modifications and medications to help reduce the symptoms and improve quality of life.
CHF is classified into two main types: systolic and diastolic. Systolic CHF occurs when the heart is unable to pump enough oxygen-rich blood to the body, while diastolic CHF occurs when the heart’s ability to fill with blood and relax between beats is reduced.
When CHF is suspected, a doctor will typically order a variety of tests to confirm the diagnosis, such as an electrocardiogram (ECG) to measure the heart’s electrical activity, an echocardiogram to assess the heart’s structure and function, and a chest X-ray to look for signs of fluid buildup in the lungs or chest. Depending on the results of these tests, a doctor may recommend lifestyle changes, such as reducing salt intake, quitting smoking, and increasing physical activity. They may also prescribe medications to reduce symptoms and help manage the condition.
