Heart failure can be the result of many different diseases. Faced with a patient with heart failure, it is necessary to understand the mechanism leading to the current state of the disease.

Grade 1 heart failure is the mildest of the four grades of heart failure. However, if the patient is subjective in treatment, it will make the disease worse quickly. Early detection and lifestyle changes to prevent disease progression help people with grade 1 heart failure recover quickly, limiting the disease to more severe levels.

Heart failure, also known as congestive heart failure, occurs when the heart doesn't work to pump blood as well as it should, and blood becomes blocked in the blood vessels (congestion). A lot of people think that heart failure only happens to adults, but actually people of all ages are at risk for heart failure, including infants, children, and adolescents.

Not all heart diseases have obvious symptoms. Some symptoms don't even appear in the chest and it's not easy to see exactly what's going on. This is especially true in the case of people who are 60 years of age or older, overweight or have diabetes, high cholesterol or high blood pressure.

Most patients with heart failure do not realize their disease, because typical signs of heart failure stage 2 appear only when the patient is exerted and quickly disappear when resting. However, if you miss the opportunity to treat the disease at this stage, grade 2 heart failure can progress more seriously and cause many dangerous complications.

Heart failure is a medical condition in which the heart muscle is unable to supply blood according to the body's needs. According to the World Health Organization (WHO), an estimated 5 million people are newly diagnosed with heart failure each year worldwide.
