1. Heart failure (HF) is a syndrome that involves dysfunction of the cardiac muscle, it occurs with “any of disorders that damage or overwork the heart muscle” (Karch, 2017 p.751). Some of the disorders that may lead to HF are: coronary artery disease, cardiomyopathy, hypertension, and valvular heart disease (Karch, 2017). What ends up happening as a result of these disorders, is that the heart muscle cannot effectively pump blood throughout the vascular system (Karch, 2017). In left-sided heart failure, the “blood backs up into the lungs which leads to pulmonary vessel congestion and fluid leakage into the alveoli and lung tissue” (Karch, 2017 p.752). In right-sided failure, the blood backs up in the venous system, which may lead to liver congestion and edema of the legs and feet (Karch, 2017).…
Florita Santos, a middle-aged woman, is admitted to the coronary care unit with a diagnosis of Left ventricular failure resulting from myocardial infarction. Her history indicated that she was aroused in the middle of the night by severe chest pain. Her skin is pale and cold, and moist sounds are heard over the lower regions of both lungs. Explain how failure of the left ventricle can cause these signs and symptoms. (4 points). Answer:…
Cor pulmonale is a condition that mainly caused from pulmonary hypertension. It’s also known as right-sided heart failure because it occurs within the right ventricle of your heart.” Cor pulmonale causes the right ventricle to enlarge and pump blood less effectively than it should”(Moore, K. 2017) . This causes increased work of the ventricle and eventually fails.…
Right sided heart failure happens when the right side of the heart is unable to pump an adequate amount of blood to the lungs and out of the right side of the heart. This either happens because the hearts muscles are unable to fully contract or they are inflamed not allowing an adequate amount of blood to enter them. This leads to a backup in venous blood. The venous blood puts pressure on the walls of the blood vessels (especially in the legs). This causes blood plasma to leak into the interstitial spaces. This causes one of the major signs of right sided heart failure which is pitting edema of the legs. But, the fluid back up does not only cause edema. The failure of the right side of the heart to load sends a smaller amount of blood to the…
Right-sided heart failure is a consequence of left ventricular failure. When the fluid pressure increases in the left ventricle, but is too weak to pump the fluid out into the aorta, the fluid regurgitates into the left atrium and subsequently backs up into the lungs. In the same manner, the right ventricle pump deoxygenated blood to the pulmonic vein but is met with great resistance due to congested lungs, thereby pushing the fluid back into the right atrium, and into the vena cava. This backing up of blood causes swelling of the abdomen, legs and ankle.…

Heart failure often happens after other conditions have damaged or weakened your heart, but the heart doesn't need to be weakened to cause heart failure. It can also happen if the heart becomes to stiff. Congestive heart failure comes from blood backing up into or congesting…
Heart failure occurs when the heart cannot pump enough blood for the body due to a weakened or damaged heart. The heart's pumping action moves oxygen-rich blood as it travels from the lungs to the left atrium, then on to the left ventricle, which pumps it to the rest of the body. The left ventricle supplies most of the heart's pumping power, so it's larger than the other chambers and essential for normal function. (American Heart Association). In left-sided or left ventricular heart failure, the left side of the heart must work harder to pump the same amount of blood. (American Heart Association). There are two types of left-sided heart failure: systolic heart failure and diastolic heart failure. Heart…
Heart failure is an ailment where the heart is not able to pump the required amount of blood to the body. Left-sided heart failure is described as when the heart cannot pump enough oxygenated blood to the body while Right-sided heart failure is when the heart cannot fill with the appropriate amount of blood.1 One or both of these may occur with heart failure. In the United States, 5.8 million people have heart failure and this number is continuing to grow.1 With the number of people with this condition growing, it is important to outline the incidence and etiology, pathophysiology, clinical manifestations, medical diagnosis, medical and pharmacological management, and prognosis of heart failure as a way to inform and decrease…
Introduction- People have to be willing to make a change in their life in order to prevent congestive heart failure., Congestive heart failure is a chronic disease that can be prevented with a proper lifestyle change, such as smoking and obesity. Smoking makes a person a high risk for getting congestive heart failure and Obesity can also put pressure on your heart to cause congestive heart failure.…
Congestive heart failure is the process in which the heart becomes in-able to maintain circulation for the requirements of the body at an effective rate, As the heart is one of the body’s vital organs, it plays an important role and has some degree of compensating mechanisms to balance the body’s needs with existing disease of the heart. Eventually when the heart is no longer able to compensate heart failure occurs; congestion will then follow, resulting in insufficient supply of blood to the body.…
Heart failure's definition is obvious from its term. Heart stops working due to lack of oxygen(1). Lack of oxygen in the artery that is coming from lung to the heart. This artery called coronary artery. The lack of oxygen in this artery is due to blocking of this artery. In this case, heart starts to adapt this condition by many ways. First, heart champers enlarge, heart contracting cells get bigger, and heart pumps faster. All these adaptive ways that heart uses just to provide body organs with enough…
Congestive heart failure distresses the heart’s function as a pump to meet the body’s needs, affecting many organs of the body including the liver, lungs, kidneys and the intestines. Untreated, this condition will affect virtually every organ in the body. (MedicineNet, 2012) According to Healthline.com congestive heart failure (CHF) is defined as, “A condition in which the heart can no longer pump enough blood to the rest of the body.” (Healthline, 2012) Heart failure is a serious disorder that may get worse with an infection or physical stress. It is often classified as either systolic or diastolic. Systolic heart failure means that your heart muscle cannot pump or eject the blood out of the heart properly. Diastolic heart failure means that your heart’s pumping chamber does not fill up with blood. In both systolic and diastolic heart failure the heart is no longer able to pump enough blood out to the rest of the body. This is especially true when you are active or exercising. (Healthline, 2012)…
Right-side heart failure occurs if the heart can't pump enough blood to the lungs to pick up oxygen. Left-side heart failure occurs if the heart can't pump enough oxygen-rich blood to the rest of the body.…
