Aortic Stenosis |Aortic stenosis is a narrowing of the aortic valve in the heart. This restricts the flow of blood through | |the valve. The left ventricle then needs to contract harder to pump blood into the aorta. Mild narrowing | |may not cause any symptoms. More severe narrowing can cause various symptoms and may lead to heart | |failure.
Running Head: Congestive Heart Failure Kimberly A McCarthy Week 5 Assignment 2 Pathophysiology Congestive Heart Failure September 24, 2014 Running Head: Congestive Heart Failure Congestive Heart Failure Congestive Heart Failure is when the heart is not properly doing its primary function, which is pumping blood efficiently through all four chambers of the heart. The heart is easily recognized as a “pump.” Many people get this confused and assume that Congestive heart failure is when the heart just stops working all together which is false. When the heart is not properly pumping blood, tissues and other body organs are not receiving the amount of blood and oxygen required to properly function. Congestive heart failure will
Right heart failure occurs when the right ventricle cannot adequately pump blood to the lungs. Blood and fluid may back up in the veins that deliver blood to the heart. This can cause fluid to leak into tissues and organs. It is important to know that both sides of the heart may fail to function adequately at the same time and this is called biventricular heart failure. This often occurs since the most common cause of right heart failure is left heart failure Next we are going to understand what hear failure is.
There are many causes of CHF, which include primary heart muscle weakness, heart valve disease, and hypertension. When the muscles in your heart can no longer pump enough blood out of the heart wall, this is called systolic heart failure. When your heart muscles become stiff and can no longer fill up, this is called diastolic heart failure. As the heart loses its ability to pump blood, blood may is backed up into other areas of the body. This causes build-up of fluid in the lungs, liver, arm, and legs.
In fact, the most common cause of heart failure is myocardial infarction. The nurse should also ask Bert if he has hypertension, another primary underlying condition causing heart failure. [pic][pic] [pic]"Do you have varicose veins?" Varicose veins are not associated with an increased risk for heart failure.
Cardiomyopathy and Congestive Heart Failure: Case Study #2 GCU Pathophysiology and Nursing Management of Client's Health NRS 410 V Cardiomyopathy and Congestive Heart Failure The main function of the heart is to pump blood to meet the needs of the body. Heart failure occurs when the heart doesn’t have the ability to pump enough blood to the different parts of the body. This can occur if there is any defect in the heart muscles or if it becomes weaker due to some other factors. When this happens the kidney receives less blood to filter. The extra fluids build up in the legs, lungs, liver and around the eyes.
This affects your circulatory system which includes your heart, kidney, and your brain. When having hypertension or high blood pressure your blood is not circulating the way it should be and that is what causes a person’s diagnosis. The feedback system cannot maintain homeostasis because there is no control over the causes of hypertension/high blood pressure. Once the causes can be controlled then the feedback system will be able to control the homeostasis. The consequences of not maintaining homeostasis balance may be being admitted to the hospital, a heart attack, stroke, aneurism, and possibly could lead to dying.
coronary heart disease Coronary heart disease is when our hearts blood supply is blocked by a build-up of fatty substances in the arteries. Over a period of time our arteries can become blocked by fats. Our arteries will then become narrow causing the amount of blood flow to our heart to be restricted. This can result in angina (chest pains). However if he arteries become completely blocked it can cause a heart attack.
B Rationale: Hypertension is a primary cause of heart failure because the increase in ventricular afterload leads to ventricular hypertrophy and dilation. Hypertensive crisis may precipitate acute heart failure is some patients, but this patient with stage 1 hypertension may not be concerned about a crisis that happens only to some patients. Hypertension does not directly cause rheumatic heart disease (which is precipitated by infection with group A -hemolytic streptococcus) or papillary muscle rupture (which is caused by myocardial infarction/necrosis of the papillary muscle).

A patient who has had multiple surgeries could also cause a lot of tissue damage and could increase the patients blood loss. 3. potential hazards: fluid balance recording is often inadequate or inaccurate, due to staff shortages, lack of training or lack of time.
