Heart failure is a disease process in which the heart loses its ability to adequately pump blood through the body.
1. Aging
The heart loses some of its blood-pumping ability as a natural consequence of aging. An eighty year old heart will not pump as effectively as a twenty year old heart.2. Heart Disease
Smoking, high cholesterol levels, hypertension (persistent high blood pressure), diabetes and abnormal blood sugar levels, and obesity all increase the risk of heart attack which can damage the heart muscle leading to heart failure. 3. High Blood Pressure
Uncontrolled high blood pressure increases the risk of heart failure by 200 percent, compared with those who do not have hypertension. Moreover, the degree of risk appears directly related to the severity of the high blood pressure. 4. Diabetes
Persons with diabetes have about a two- to eightfold greater risk of heart failure than those without diabetes. Women with diabetes have a greater risk of heart failure than men with diabetes. Part of the risk comes from diabetes' association with other heart failure risk factors, such as high blood pressure, obesity, and high cholesterol levels. However, the disease process in diabetes also damages the heart muscle.5. Heart Valve Disease and Infection
In some people, heart failure arises from problems with heart valves,the flap-like structures that help regulate blood flow through the heart. Infections (such as rheumatic fever)in the heart are another source of increased risk for heart failure.6. Genetic Disorders
Genetic abnormalities that may cause abnormalities of the heart structures contribute to the risk for certain types of heart disease, which in turn may lead to heart failure. However, in most instances, a specific genetic link to heart failure has not been identified.
