Cardiovascular disease (CVD) is a chronic illness. Globally CVD is responsible for the deaths of many and in South Africa; it is now gaining more recognition as its prevalence rate is increasing. Particular groups of society are at a higher risk for CVD. This essay shall look at the health status of cardiovascular disease in South Africa. It will draw upon studies and research that have been completed within a South African context in order to gain more information about those most at risk and the actions that can be taken to halt this escalating problem.
Cardiovascular disease refers to disease of the heart and blood vessels. The most common outcomes of CVD are heart attacks, strokes, heart failure and disease of the heart muscle (Joubert et al., 2008). A heart attack or myocardial infarction (MI) results from a heart muscle that cannot pump sufficient blood to the rest of the body due to reduced blood flow (Joubert et al., 2008). A stroke or cerebrovascular accident (CV) is the result of interrupted blood flow to the brain which leads to the brain cells dying due to a lack of oxygen (Joubert et al., 2008).
Worldwide within the next 20 years, the occurrences of cardiovascular disease are predicted to rise by at least 150% in developing countries (Yusuf, Reddy, Ounpuu and Anand (2001). In Africa- it is believed that it will affect 1.3 million people during that time, according to Yusuf et al. (2001). In South Africa, cardiovascular disease is responsible for almost 10% of healthy years of life lost and is therefore second only to HIV/AIDS- which illustrates its prominence as a chronic disease (World Health Organisation, 2007). South Africa as a country has had a difficult history and the burden of these non-communicable disorders...

Taking the studies about cardiovascular disease in South Africa into consideration, it is evident that more research needs to be conducted on a wider population and bigger cohort. The prevalence rates emerging are far greater than previously imagined amongst Black South Africans. This essay has looked at the issue of cardiovascular disease within a South African context- drawing upon relevant studies highlighting the communities and individuals most at risk. It has also demonstrated that a health psychology focus can positively aid behaviour change thereby reducing the risk of cardiovascular disease.
As early as the 1800s clinicians began to take a closer look at elevated blood pressure levels, they soon found high correlation between hypertension, stroke, and other heart diseases. They also established that high levels of blood pressure effected both privilege and underprivileged, and within the years they have noted the disease have become more prevalent in the African American culture. Long term studies, such as randomized controlled trial studies, unveiled
Cardiomyopathy, by definition, means the weakening of the heart muscle. The heart is operated by a striated muscle that relies on the autonomic nervous system to function. Cardiomyopathy is diagnosed in four different ways based on what caused the illness and exactly what part of the heart is weakened. The four main types of cardiomyopathy are dilated cardiomyopathy, hypertrophic cardiomyopathy, restrictive cardiomyopathy, and arrhythmogenic right ventricular dysplasia. One other category of cardiomyopathy that is diagnosed is “unclassified cardiomyopathy.” Unclassified cardiomyopathy is the weakening of the heart that does not fit into the main four categories.
Heart disease is one of the most common causes of the mortality and morbidity in most well developed countries. They come in different forms such as stroke and other cardiovascular diseases and it’s the number one cause of death in the state of America. In the year 2011 alone nearly 787,000 people were killed as a result of this epidemic. And this included Hispanic, Africans, whites and Americans. As for the Asian Americans or pacific Islanders, American Indians and the natives of Alaska, the concept to them was a second only to cancer. However, statistics has proved that a person gets heart attack every 34 seconds and in every 60 seconds, someone dies out of it which include other related event. Additionally, majority of the women are the
Atherosclerosis is a disease that occurs when arteries become blocked, inflamed, or hardened. As a result of this, blood cannot easily pass through the artery, and blood pressure increases. Many people suffer from atherosclerosis as they age, but young people can be affected by atherosclerosis also. There are many preventative steps that can be taken to decrease the risk of atherosclerosis; however, if atherosclerosis does develop in the arteries, medications can be given to help the individual receive adequate blood flow to important tissues. Atherosclerosis is a very serious condition that requires medical attention and a change in life style because it is a precursor to many dangerous and potentially fatal diseases.
If we were to apply a longitude exposure study over the span of 42 years from the time an inner-city child is born, we may conclude that life experiences resulting from potential malnutrition, underprivileged environments, and overall lack of health education are the leading contributors to adult African American deaths. Studies show that 8 of the 10 leading causes in the deaths of African Americans are medical disease, which with proper education and care may have been prevented and/or addressed earlier in their life to diagnose and treat. The fact is Heart Disease is the leading cause of deaths for African Americans. When compared to other ethnicities, some form of heart disease causes 24.5% of African American deaths. These numbers are astounding considering Blacks make up approximately only 14.2% of the total U.S. population. The contributing factor is lack of knowledge and family medical screening. Understanding the history of your genial line specific to your race and ...
Cardiovascular Disease is defined by the American Heart Association as “Heart and blood vessel disease”. Atherosclerosis of the arteries, can lead to hypertension, heart failure, arrhythmias, heart valve problems, myocardial infarctions or a stroke (AHA, 2016). In this paper, all of heart and vessel diseases aforementioned, will be considered cardiovascular disease (CVD). According to
Since 1960 the age-adjusted mortality rates for cardiovascular disease (CVD) has declined steadily in the U.S. due to multiple factors, but still remains one of the primary causes of morbidity and premature mortality worldwide. Greater control of risk factors and improved treatments for cardiovascular disease has significantly contributed to this decline (Centers for Disease Control and Prevention, 2011). In the U.S. alone it claims approximately 830,000 each year and accounts for 1/6 of all deaths under the age of 65 (Weiss and Lonnquist, 2011). Based on the 2007 mortality rate data an average of 1 death every 37 seconds is due to cardiovascular disease (Lloyd-Jones et al., 2009). Controlling and reducing risk factors is crucial for saving lives. There are a number of contributing risk factors for cardiovascular disease, which may appear in the form of hereditary, behavioral, and psychological, all of which ultimately converge in social or cultural factors.
Heart disease is of utmost and imperative concern in the United States. It stands at the top of the list for causes of death in the U.S., and it can be absolutely devastating (Centers for Disease Control and Prevention [CDC], 2013). In part one of the health disparities paper, disparity in relation to heart disease was pointed out in those of low socioeconomic status and/or minorities. Part two of this paper has been streamlined towards a more specific minority: African Americans women. The reason for focusing on the African American women population is that there is a huge amount of disparity seen specifically in this group. As of 2009, African Americans as a whole had 30% more of a chance of dying from cardiovascular disease than Caucasians (U.S. Department of Health & Human Services Office of Minority Health [OMH], 2012). The rate of Cardiovascular Disease in African American women specifically is higher at 48.9% than the rate of CVD in African American men at 44.4%, showing even greater disparity in African American women (American Heart Association, 2013). The goal of this paper is to identify and appraise two different articles surrounding this topic. Both articles involve an intervention in which similar community prevention programs were implemented in hopes to reduce the risk of CVD in African American women.
CHD is primarily due to atherosclerosis, which is the blockage of blood flow in the arteries due to the accumulation of fats, cholesterol, calcium and other substances found in the blood. Atherosclerosis takes place over many years, but when the blood flow becomes so limited due to the build up of plaque in the arteries, there becomes a serious problem. “When...
Cardiovascular disease (CVD) is a group of disorders or diseases that involves the heart and blood vessels, or both. Cardiovascular disease is the leading cause of death amongst individuals living the United States. Some diseases associated with CVD consist of: coronary artery disease, congenital heart disease and pulmonary embolism (U.S. National Library of Medicine).

(Slide 2) What is Cardiomyopathy? If we break down the word we can see “Cardio” which means of the heart, “myo” which means muscle, and “pathy” which means disease, therefore cardiomyopathies are diseases of the heart muscle. (Slide 3) There are 3 main types of cardiomyopathies; hypertrophic, dilated, and restrictive. I will only be discussing dilated cardiomyopathy, which is characterized by the enlargement of the hearts chambers with impaired systolic function. It is estimated that as many as 1 of 500 adults may have this condition. Dilated cardiomyopathy is more common in blacks than in whites and in males than in females. It is the most common form of cardiomyopathy in children and it can occur at any age (CDC).
Oxygen was first admitted to the client with chest pain over 100 years ago (Metcalfe, 2011). Chest pain is a large bracket that can contain many different conditions, but for the purpose of this analysis it is focused manly upon a myocardial infarction. A myocardial infarction is mainly referred to as a heart attack, and occurs when one or more coronary arteries leading to the heart reduce or completely stop blood flow (Tuipulotu, 2013 ). Administering high concentrations of oxygen to patients with chest pain is now embedded in guidelines, protocols and care pathways, even with a lack of clear supporting evidence (Nicholson, 2004 ). High concentration of oxygen means that up to 60% is administered (Knott, 2012). More recent research has suggested that the use of oxygen in this scenario is unnecessary and can lead to unwanted side effects, especially in normoxic cardiac patients (Moradkham & Sinoway, 2010 ). The aim of this comparative analysis is to dismantle and understand both the benefits and risks of the commonly known practice of administration of oxygen to the client with chest pain. Through completing this analysis using recent and appropriate evidence a more improved practice can be given and understood.
Heart disease describes a range of conditions that affect your heart. Diseases under the heart disease umbrella include blood vessel diseases, heart rhythm problems, and heart defects. The major cause of this is a build-up of fatty plaques in the arteries. Plaque build-up thickens and stiffens the vessel walls, which can inhibit blood flow through the arteries to organs and tissues.
Social cognitive theory relates the performance of a behaviour change to an individual’s expectations of his or her particular performance and their probability in accomplishing that particular change (Plake). In regards to this specific model there are two types of expectations, outcomes and efficacy. Outcome expectations referring specifically to an individual’s belief that performance of a specific task or behaviour will lead to a specific outcome. Efficacy expectations refer to a person’s belief that they will be able to perform that behaviour change. All of the above mentioned facts can link specifically to various health behaviours that require changing in regards to Hypertension. When looking at specific health behaviours that are most often focused on there are five main areas which become prominent and seem to be the most problematic when dealing spe...
