What are the symptoms of heart failure? Heart failure is often considered the end - stage of heart disease. It can be divided into acute heart failure and chronic heart failure.

For acute heart failure, patients usually have a history of hypertension, meaning they have high blood pressure. Additionally, it may be caused by improper or excessive intravenous fluid administration. Acute heart failure is relatively rare.

The more common type is chronic heart failure. Patients with chronic heart failure may have a previous chronic medical history, such as diabetes, coronary heart disease, rheumatic heart disease, or hypertensive heart disease. When patients with these medical histories develop symptoms of heart failure, it is called chronic heart failure.

There are symptoms of the primary disease as well as those specific to heart failure itself.

In left - sided heart failure, pulmonary congestion occurs, leading to difficulty breathing.

In right - sided heart failure, there is systemic circulation congestion, which can cause hepatic congestion and enlargement of the liver. If this condition persists for a long time, it may lead to congestive cirrhosis. In addition, patients may also experience lower limb edema.
