When the pumping function of the heart is impaired, accompanied by an ejection fraction EF less than 40%, it is called systolic heart failure. Heart failure examination and treatment of systolic heart failure require strict adherence to the doctor's instructions to limit dangerous complications.

In the treatment of stage 3 heart failure, in addition to medication and lifestyle adjustments, doctors also consider the direction of using a left ventricular assist device. One of them is a ventricular assist device, which is often indicated in patients with severe or end-stage heart failure.

Acute heart failure is the sudden onset of signs and symptoms of heart failure that requires urgent intervention. Besides the causes of acute heart failure, other predisposing factors may play a role in making the condition worse.

Treatment of heart failure is divided into 4 levels according to each stage A, B, C and D. There are 2 main treatment options: medication and non-drug treatment. The goals of heart failure treatment are to reduce symptoms, limit hospitalization, and prolong survival.

Cor pulmonale is a lung disease that leads to secondary right heart failure. The incidence of the disease increases in countries with many smokers and polluted environments because this is a risk factor for chronic lung disease. If chronic cor pulmonale is properly monitored and treated, the prognosis is good and the disease progresses more slowly.

Ultrasound assessment of diastolic function is an integral part of the routine evaluation of patients with symptoms of heart failure or dyspnea. The Echocardiographic Society generally recommends a comprehensive evaluation of diastolic function, including multiple Doppler-based parameters and two-dimensional echocardiography to grade diastolic dysfunction.
