Congestive Heart Failure Research Paper
Congestive heart failure, affecting about 5 million Americans, is the leading cause of death among Americans, accounting nearly 700,000 deaths. It is twice as many as stroke and seven times as many as breast cancer [Herold, 2001]. Sudden cardiac failure, a form of congestive heart failure in which the heart fails without advanced warning, causes about half of the total deaths. For the remaining half, congestive heart failure doesn’t mean that the heart completely stops working; it means that the heart muscle has deteriorated so much that the heart can no longer pump as much blood as the body needs. However, a number of deaths are being prevented because of available heart transplant. But the number of prevented deaths is too small which accounts …show more content…
Currently, the simplest method to counteract congestive heart failure is the use of medication. Medication can be effective if the heart is treated during the initial stages of the failure; however, if the heart is already in end stage congestive heart failure, medication is highly ineffective [Gorman and Park, 2001]. For people with a heart in the end stage of congestive heart failure, heart transplant surgery is the only biological alternative available. During heart transplant surgery, the diseased heart is removed and replaced with a healthy heart that was donated by a person who had died for other reasons. However, due to the relatively small number of donor hearts that become available each year, many people with end stage congestive heart failure die while waiting to receive a donated …show more content…
One mechanical device that has assisted people with congestive heart failure is the ventricular assist device (VAD). The VAD is a small mechanical pump that is inserted into the ventricle and supplies a constant flow of blood in place of the ventricle’s pumping motion [Lemonick, 2000]. Although the VAD relieves the heart of much of its pumping duties, it does not cure the heart of its diseases, and therefore the heart continues to deteriorate and slowly fails. As a result, the ultimate solution in solving health problems caused by congestive heart failure may be the total artificial heart which is a mechanical device that permanently replaces the entire heart instead of just assisting the diseased heart like the VAD does.

    Cardiac Pacemaker Business

    The legacy af Medtramc Corporation, the company that created the cardiac pacemaker industry, is a proud one. Starting fram its earliest pacemakers, which had to be carried outside the body, Medtramc had achieved dramatic improve ments ln the functionality, size and reliabilit)' Df these d evi ces. ln 50 doing it had extended the lives, and improved the quality Df lHe, for hundreds Df thousands of p eopIe in whom pacemakers had been implanted. The pacemaker has been designated as one of the ten most outstanding engineering achievements in the world over the past 50 years, along with the digital compu ter and the Apollo 11 moon landing. 1 Medtromc, which in 1995 booked operating profit of $300 million on revenues of $1.7 billion, had been founded in 1957 in Minneapolis, Minnesota by Earl Bakken, a researcher and inventor who had to his credit patents on several af the crucial techn ologies that led to the modern heart pacemaker. Pacemakers were small, battery-powered devices wruch, when implanted within a patient, helped a malfunctioning heart to beat in a steady, fixed rhythm. Because Medtronk was the first entrant into the p acemaker field and built a strong technological lead, it enjoyed a substantial portion (over 70%) of the market sharp for cardiac ['",cing through the 19605. Building upon Medtronic's legacy Df leadership was not easy, however. ln the face of increasing competition, rapid technological change and tightening market and regulatory demands for product quality, Medtromc saw its market share cut by more than half between 1970 and 1986. Though it had invested heavily in technology and product developrnent over this period, much of that investment had been unproductive. Many projects faiJed to produ ce product designs that could be launched competitively, and the features and functionality of most of the products the company was able to…

    Congestive Heart Failure: A Case Study

    Congestive Heart Failure (CHF) affects a more people because of the increased survival rate post heart attacks leaving the patients with residual heart problems. According to Dr. Grossman, "in the US: More than 3 million people have CHF, and more than 400,000 new patients present yearly. Prevalence of CHF is 1-2% of the general population" (2006). In an effort to improve patient outcomes the patient education department undertook a project that included the use of common guidelines, Core Measures, to develop an education tool for patient use. The team goal was to promote self-management through patient education and lifestyle changes. After several months of planning and development the CHF tool was put into service. The information provided…

    The Pros And Cons Of The Artificial Heart

    The first artificial heart for humans was invented in the 1950s, but it wasn't until 1982 that a working artificial heart, the Jarvik-7, was successfully implanted in a human patient. Your heart is the engine inside your body that keeps everything running, the heart is a muscular pump that Like any engine, if the heart is not well taken care of it can break down and pump less efficiently, a condition called heart failure, which runs oxygen and blood through your lungs and body. In a day, your heart pumps about 2,000 gallons of blood. Until recently, the only option for many severe heart failure patients has been heart transplants. Today, the most common artificial heart is the SynCardia temporary Total Artificial Heart, accounting for 96% of all artificial heart transplants. And it doesn't come cheap, with a price tag of around $125,000.…

    Cardiovascular: Heart Rate Declines

    Coronary Artery Disease (CAD) is the most common type of heart disease. I’m here to tell you all, it’s the leading cause of deaths in the United States in both women and men. (CAD) happens when the arteries that supply blood to the heart muscle becomes harden and narrowed. This is due to the buildup of cholesterol and/or plaque on the inner walls (MedlinePlus, 2012). To reduce your risk of getting (CAD) can potentially lead to heart failure. Leading to the next disease I want to discuss is Congestive Heart Failure. (CHF) is a condition in which the heart’s function as a pump is inadequate to meet the body’s needs (MedicineNet, 1996). From known knowledge, (CHF) can be based on many reasons for example, individuals medical history. I know as we age we all dislike going to the doctor’s office or hospital, but I’m here to tell you, we all need to go more often than normal.

    Causes Of Heart Failure

    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 Disease (Chf)

    The main function of a healthy heart is to ensure proper blood flow throughout the body and supplying all the organs with the nutrients that are necessary for survival. Congestive heart failure (CHF) is also known as Congestive heart disease, but for this paper we will use failure, Consistent with the research. Congestive heart failure is a disease that primarily causes the heart to be compromised. This leaves the heart unable to perform the main function of pumping blood throughout the body to maintain homeostasis. Congestive heart failure affects mostly individuals 65 years and older; however it can happen at any time. (Anderson, et al 2010). According to Goldberg & Konstam, “It is also one of the most common forms of heart disease. Approximately 4.9 million Americans suffer from CHF, with about 400,000 new cases diagnosed annually.” (as cited in Mithal, Mann, & Stone, 2002, p. 46). Prevention methods are important factors for avoiding this disease. There are several treatments available for congestive heart failure that focus on reducing fluids from the body to remove congestion from the heart or reduce blood pressure in the arteries.…

    Heart Failure Essay

    2.1) Heart transplants are recommended to patients when severe heart failure is present or when one or both ventricles are not functioning like how they should be. In many forms of congenital heart disease, ventricular failure may also occur. It is more common in congenital defects with a single ventricle or when irreversible heart failure occurs from long-standing valve obstruction or even leakage. Patients who had the Fontan procedure as a child (which includes helping complex congenital heart defects) may need a heart transplant. This is because the blood flow through the venous system is slow and the veins are congested. This leads to protein loss, fluid accumulation and swelling.…
