What is Heart Failure?

According to MayoClinic.Org,” Heart failure, sometimes referred to as congestive heart failure, occurs when your heart muscle doesn't pump blood as well as it should. Certain conditions, such as narrowed arteries in your heart (coronary artery disease) or high blood pressure, gradually leave your heart too weak or stiff to fill and pump efficiently.” Web. . January 12, 2016
There are contributing factors that can lead to heart failure such as coronary artery disease, diabetes, obesity, and high blood pressure. Management of these diseases such as daily exercise, weight loss, decreasing sodium intake, and managing stress can lower the risks of developing heart failure.

Viruses. A viral infection may have damaged your heart muscle.
9. Tobacco use- Using tobacco can increase your risk of coronary artery disease and heart failure.
10. Obesity- Those who are obese have a higher risk of developing heart failure because the heart has to work harder.
11. Irregular heartbeats- These abnormal rhythms, especially if they are very frequent and fast, can weaken the heart muscle and cause heart failure
Complications of heart failure include:
1. Kidney damage- Heart failure can reduce the blood flow to your kidneys, which can eventually cause kidney failure if left untreated. This can lead to the need for dialysis.
2. Heart valve problems-The valves of your heart keep blood flowing in the proper direction. If there is a problem, like stenosis, which is narrowing where the valve opens, blood can back flow in the wrong direction.
3. Heart rhythm problems- Heart rhythm problems (arrhythmias) can be a potential complication of heart failure.
4. Liver damage- right sided heart failure can lead to a buildup of fluid that puts too much pressure on the liver. This fluid backup can lead to scarring, which makes it more difficult for your liver to function

Other contributors include non-cardiac conditions such as renal dysfunction, diabetes mellitus, anemia, and the side effects of medications (nonsteroidal anti-inflammatory drugs, calcium-channel blockers, and thiazolidinedione).

Classifications and Stages of Heart Failure
Doctors usually classify patients' heart failure according to the severity of their symptoms. The table below describes the most commonly used classification system, the New York Heart Association (NYHA) Functional Classification. It places patients in one of four categories based on how much they are limited during physical activity.

Class Patient Symptoms
I No limitation of physical activity. Ordinary physical activity does not cause undue fatigue, palpitation, dyspnea (shortness of breath).
II Slight limitation of physical activity. Comfortable at rest. Ordinary physical activity results in fatigue, palpitation, dyspnea (shortness of

    Insulin resistance can cause extremely detrimental effects on cardiac contractility by decreasing the body’s ability to supply ATP. Once again, this can lead to cardiac remodeling and heart failure. This heart failure will lead to the activation of RAAS which will perpetuate the cyclical problem. Between the mechanical and the neurohumoral issues seen with systolic ventricular dysfunction, one can see how each system and mechanism feeds the other. Hypertension from an unhealthy life style can cause a small amount of damage to the left ventricle.…

    The blockage harms part of the heart muscle because it is no longer getting oxygen from the blood. Most heart attacks are caused by a blood clot, which blocks one of the coronary arteries (Emedicinozone, 2010). Occasionally, a heart attack can be caused by a spasm or tightening of the coronary artery. Coronary arteries are blood vessels that aid in supplying the heart muscles with oxygen-rich blood (NIH, 2012). In a Coronary Artery Disease, the coronary arteries, narrow inside and harden due to build up fatty materials known as plaque.…

    Acute myocardial infarction is caused by the narrowing or the blocking of the coronary arteries that supply the heart muscle with oxygen. A myocardial infarction occurs when ischemic intracellular changes become irreversible and necrosis. The patient becomes more susceptible to another occurrence of a myocardial infarction or even lead up to heart failure. Coronary artery disease is the main cause of a myocardial infarction. Many patients that have an acute myocardial infarction often have chest pains that indicate the lack of oxygen to the heart muscle.…

    Heart failure develops time, as the heart’s pumping action grows weaker. This can affect the right side of the heart only, or it can affect sides of heart. However, most cases involve both side of the heart. Right side heart failure occurs if the cant pumps enough blood to the lungs to pick up oxygen. Left side heart failure occurs if the heart can’t pump enough oxygen-rick blood to the rest of the body.…

    The plaque narrows down the arteries and reduces the blood flow in the heart muscles. Once the arteries become narrow, blood clotting can happen and this can block the flow of blood. Since the flow of blood and oxygen are blocked and may result to a heart attack, also known as angina. In the long term, coronary heart disease can lead to heart failure and arrhythmias. It is also the most common of all the heart diseases and it the number one cause of death for both men and women in the US.…

    Coronary artery disease is said to be the most common cause of heart failure, as time goes on your body’s arteries become narrow from build-up of fatty deposits (atherosclerosis), therefore blood flow is reduced. Eisen et al state that a myocardial infarction is one major cause of heart failure in patients with coronary artery disease (10). When you have a high blood pressure this is called hypertension, a high blood pressure means that the heart is working harder to circulate the blood, overtime the heart muscles becomes stiff or too weak to efficiently pump the blood. The primary aetiology of heart disease is difficult to determine especially when a patient has many different diseases that could potentially trigger heart failure. Some other causes of heart failure are diabetes mellitus and atrial fibrillation (8).…
