The heart's main function is to pump blood, carrying oxygen and nutrients to the body's tissues and removing waste products.

High blood pressure, diabetes, and obesity are all risk factors for developing heart failure.

Systolic heart failure occurs when the heart muscle is unable to contract forcefully enough, while diastolic heart failure occurs when the heart muscle is unable to relax properly.

Shortness of breath, fatigue, and swelling in the feet, ankles, and legs are all common symptoms of heart failure.

Heart failure is diagnosed based on a combination of physical examination, medical history, blood tests, chest X-ray, electrocardiogram (ECG), and echocardiogram.

Treatment options for heart failure include medications, lifestyle changes, surgery, and heart transplant.

Making healthy lifestyle changes, such as eating a healthy diet, exercising regularly, maintaining a healthy weight, reducing stress, and limiting alcohol and caffeine intake, can help manage heart failure.

The prognosis for heart failure depends on the severity of the condition, but with proper treatment, it can be managed and the risk of death can be reduced.

Sudden cardiac death is the leading cause of death from heart failure, accounting for about half of all deaths.

Family history of heart failure, age over 65, and male gender are all risk factors for developing heart failure.

Systolic heart failure is the most common type of heart failure, accounting for about two-thirds of all cases.

Difficulty breathing while lying down is a common symptom of diastolic heart failure.

The goal of treatment for heart failure is to improve the heart's pumping ability, reduce symptoms, and prevent complications.

ACE inhibitors, beta-blockers, and diuretics are all commonly used medications to treat heart failure.

A heart transplant is performed to replace a diseased heart with a healthy one in patients with end-stage heart failure.
