Cardiovascular Disease

Cardiovascular disease (CVD) has been identified as a health priority area because it is major health and economic burden on Australia. It is one of the leading causes of sickness and death in Australia, although there are significant differences in the incidence and prevalence of the disease among population subgroups. CVD can be attributed to a number of modifiable risk factors.

The nature of CVD

Cardiovascular disease (CVD) refers to damage to, or disease of, the heart, arteries, veins and/or smaller blood vessels. The three major forms of this disease are: * Coronary heart disease – the poor supply of blood to the muscular walls of the heart by its own blood supply vessels, the coronary arteries * Stroke – the interruption of the supply of blood to the brain * Peripheral Vascular disease – diseases of the arteries, arterioles and capillaries that affect the limbs, usually reducing blood supply to the legs

Cardiovascular disease is most evident as stroke, heart attack, angina, heart failure and peripheral vascular disease.
Atherosclerosis is the underlying cause of most of these conditions. This is the build-up of fatty and/or fibrous material on the interior walls of arteries. This build-up hinders the flow of blood to the body’s tissues and also acts to increase blood pressure. Often, the build-up occurs in patches known as atheroma (thickened area of fatty and fibrous deposits on the inside surface of arteries, resulting in atherosclerosis) or plaque, and is characterized by presence of cholesterol. The development of atheroma tends to decrease the elasticity of the arteries and limits the flow of blood.

Cvd and Trancendetalism

...James Miller 10143 02/12/12 Ms. Freeman Today’s Transcendentalism Have you heard a song like “Handlebars,” or “Prayer of the Refugee”? Those are both very good songs, but have you ever realized that they have to do a lot with nature, confidence, and self-reliance? Those characteristics have to do with transcendentalism. Even today, despite transcendentalism is two hundred years old, transcendentalism can be found in modern songs such as “I Can Ride My Bike with No Handlebars”. Self reliance is when you rely on nobody but your self; where you don’t rely on technology or your buddy to do stuff. In the song “Handlebars” it says “I can make a living off a magazine, I can design an engine that gets 64 miles to the gallon of gasoline…” The Flobots are inferring that they can make a living off anything, relying on nothing but themselves to survive. While in the exert from “Walden”, it says “where I sat, there I might live, and the landscape radiated from me accordingly.” What Henry Thoreau is saying is that wherever he may go he will live; relying on nobody but himself and only himself to survive. Both the Flobots and Thoreau are saying that they will rely on no one but themselves to live and survive. Going against the flow, swimming up river, these are all ideas of free-thought. Free though is where someone does something or thinks something that not everyone does or is thinking. In the song “Handlebars” it says “I can ride my bike with no handlebars, no handle......

Literature Review Cvd

...Cardiovascular diseases (CVD) are one of the foremost origins of morbidity and mortality in the United States today, and the rates have grown exponentially over the last few decades. There is a number of health related factors and behaviors that contribute to the onset of CVD and its contribution to other well-known diseases. Implementing appropriate life style changes, certain medications, and education can contribute to the early detection of CVD and can have the potential to modify or alter the course of this deadly disease. Kehler, Christensen, Risor, Lauritzen, and Christensen (2009), reported “that patients who had a discussion with their doctor about cardiovascular disease including information about the disease, knowledge about the disease, and perception of risk and prevention strategies indicated that they were able to incorporate healthy lifestyle changes into their diet”. Through education and recognition, healthcare providers can assist patients in achieving healthy lifestyles and initiate ways to decrease risk factors associated with CVD. The health promotion model (HPM) can be utilized to enhance patients’ awareness for prevention, intervention, and perception of risks related CVD. The contents included in this paper will discuss how CVD is defined medically and through patients’ perspectives; the prevalence of CVD in the United States; precipitating factors of CVD; vulnerable groups of CVD; and a theoretical framework of the HPM for CVD.

Heart Disease Behavioral Risk Factors

...types of CVD. Almost 60 million Americans have one or more types of heart and circulatory disease. Although it is hard to imagine anything favorable associated with CVD, given those grim statistics, the good news is that it can often be prevented. Risk factors about your health include: * Traits (such as a family history of high cholesterol) * Conditions (such as high blood pressure) * Habits (such as eating a high-fat diet) These kinds of factors are linked to an increased likelihood of developing a particular disease. Risk factors can help predict the probability that you will develop a certain disease. But they do not cause the disease to occur. Think of risk factors as weights on a scale. The more risk factors you have for a particular disease, the more the scale tips in favor of you getting it. That is why we all know people who have had risk factors for a particular disease, yet have lived to a ripe old age without getting it. Like any predictors, risk factors are not certainties. Having a risk factor for a particular disease only means you’re more likely to get it-it does not mean for certain that you will. It is also important to remember that not having a risk factor for a disease does not mean that you cannot or will not get it either. Cardiovascular disease risk factors are those traits, conditions or habits that are associated with an increased likelihood of developing CVD. A person who has at least one CVD risk factor is more likely to develop......

Cardiovascular Morbidity

...(median age 46 years) treated with thyroidectomy in 1986–2007 in Finland and among 12 991 reference subjects. Firstly, the hospitalizations due to cardiovascular diseases (CVD) were analysed until thyroidectomy. Secondly, the hazard ratios for any new hospitalization due to CVDs after the thyroidectomy were calculated in Cox regression analysis adjusted with the prevalent CVDs at the time of thyroidectomy. Results The risk of hospitalization due to all CVDs started to increase already 5 years before the thyroidectomy, and by the time of the operation, it was 50% higher in the hyperthyroid patients compared to the controls (P< 0·001). After the thyroidectomy, the hospitalizations due to all CVDs (HR 1·15), hypertension (HR 1·23), heart failure (HR 1·17) and valvular diseases or cardiomyopathies (HR 1·55) remained more frequent among the patients than among the controls for 20 years after thyroidectomy. The increased morbidity was not clearly related to the aetiology of hyperthyroidism. Despite the increased CVD morbidity among the patients, there was no difference in cardiovascular mortality. Conclusions The present study shows that hyperthyroidism increases the risk of hospitalization due to CVDs and the risk is sustained up to two decades after effective surgical treatment. However, there was no excess CVD mortality in the middle-aged patient cohort studied. Introduction Hyperthyroidism is a common disease, with a prevalence of approximately 2·5% among women and 0·6% in......

...JOURNAL: Mayo Clinic Proceedings DATE OF JOURNAL: 2014-09-12 PAGES: 1187 TO 1194 Both exercise as well as physical activity has been said to decrease the risk of sudden cardiac death and acute myocardial infractions. However, the question of whether excessive exercise can increase Cardiovascular disease mortality has yet to be answered. We know that endurance training actually causes the cardiovascular system to adapt as to increase exercise capacity. These Adaptations include the enlargement of the 4 heart chambers, as well changes in the thickness of the left ventricular wall. Using the National Walkers' and Runners' Health studies the Mayo clinic took a look at the relationship between exercise energy and Cardiovascular disease (CVD) as it related to mortality in heart attack survivors. They used a baseline survey questionnaire to be sure that all of their subjects were identified as having previous heart attacks. This gave the Mayo Clinic a total of 942 male subjects and 631 female subjects from the National Walkers Health studies. The Mayo clinic also had 678 males and 128 females from the National Runners Health Studies. Using the questionnaires given to each of these subject the Mayo clinic then found the walkers energy expenditures by using MET h/d however they converted distance walked weekly into duration and then they calculated the average hours walked per day. The MET value corresponded to their reported pace. Now the runners on the other hand was......

Cohort Follow-Up Studies: Cardiovascular Disease (Cvd)

...Cohort Follow-up Studies: Cardiovascular Disease (CVD) Latavia M. Walston Strayer University, Epidemiology Professor Godson 2/20/2015 Abstract What Causes of CVD Scientist and related health- care providers often use study modules from an epidemiological position to probe unanticipated devices associated to infection, and they come up with solutions to target key factors for therapy and possible prevention. Many modules make this probable for distinguishing basic procedures, risks and outcomes. Cohort follow-up studies cover a specific area of study that labels a subject matter when the outcome of the disease is not visible. Then the study compares the incidence of outcome between exposed and unexposed persons past, present, and future. In simple terms, cohort studies measure exposure, measure outcome and methods of follow-up. For instance cohort studies would be used to examine Cardiovascular Disease (CVD) which affects millions of people worldwide especially the African American race and is often limited to the Asian culture. According to the American College of Cardiology CVD is the largest single cause of death among women. The economic impact in the United States although difficult to estimate figures show an amount over $400 billion was spent in 2006 on health care as a result of lost productivity compared to other deadly diseases, (American Heart Association [AHA], 2007). The cohort follow-up study can either be viewed from a prospective...

Data Sources: MEDLINE, Embase, Cochrane Central Register of Controlled Trials, Cochrane Database of Systematic Reviews, and Database of Abstracts of Reviews of Effects were searched from January 2005 to 29 January 2013, with manual searches of reference lists and gray literature. Study Selection: Two investigators independently selected and reviewed fair- and good-quality trials for benefit and fair- and good-quality trials and observational studies for harms. Data Extraction: Dual quality assessments and data abstraction. Data Synthesis: Two large trials (n = 27 658) reported lower cancer incidence in men taking a multivitamin for more than 10 years (pooled unadjusted relative risk, 0.93 [95% CI, 0.87 to 0.99]). The study that included women showed no effect in that group. High-quality studies (k = 24; n = 324 653) of single and paired nutrients (such as vitamins A, C, or D; folic acid; selenium; or calcium) were scant and heterogeneous and showed no clear evidence of benefit or harm.

Chapter 10 Cvd & Cancer

...United States as well as the rest of the world. Cardiovascular disease (CVD) comprises a group of diseases that includes two major categories: diseases of the heart and cerebrovascular disease (primarily stroke). Cancer is a disease characterized by uncontrolled cellular growth and reproduction. Cancer can occur in any part of the body, but we’ll discuss a few that are of the greatest importance to women’s health: breast cancer, lung cancer, cancers of the reproductive system, and a few others. More lives are claimed by CVD than by the next five leading causes of death combined. Cardiovascular deaths usually occur in later years when women are beset with a variety of comorbid conditions, such as high blood pressure, high blood cholesterol, osteoporosis, and diabetes. The two major forms of CVD are heart disease and stroke; of these, coronary heart disease is the major killer. Strokes, however, also cause many deaths, and they disproportionately affect women—6 of 10 people who die from strokes are women. Cardiovascular disease imposes a heavy burden on the medical care system in the United States, particularly on emergency medical departments and hospitals. Clinical care of CVD patients is costly and often prolonged. Cardiovascular disease often affects individuals during their peak productive years at work, causing significant disruption to families who are dependent on the person’s income. The high rate of CVD also carries a burden for the countries that lose productive......

...Anxiety is a complex emotion identified by various levels of agitation. It is caused by reaction to a threat or perceived threat that generates a ‘fight or flight’ response. In other words, when we experience situations where we are at risk, uncertain, threatened or attacked, we become anxious and take steps to address the concern. From here our natural instincts take over, forcing us to confront it (fight) or escape (flight). At the extreme, anxiety disrupts and unset- tles behaviour by lowering the individual’s concentration and affecting their muscular control. Sporting contests and competitions may contribute to anxiety because of the unpredictable nature of performance or the uncertainty of the outcome.

Cohort Follow-Up Studies: Cardiovascular Disease (Cvd)

...Causes of cardiovascular disease While cardiovascular disease can refer to many different types of heart or blood vessel problems, the term is often used to mean damage caused to your heart or blood vessels by atherosclerosis (ath-ur-o-skluh-RO-sis), a build-up of fatty plaques in your arteries. This is a disease that affects your arteries. Arteries are blood vessels that carry oxygen and nutrients from your heart to the rest of your body. Healthy arteries are flexible and strong. Over time, however, too much pressure in your arteries can make the walls thick and stiff — sometimes restricting blood flow to your organs and tissues. This process is called arteriosclerosis, or hardening of the arteries. Atherosclerosis is the most common form of this disorder. Atherosclerosis is also the most common cause of cardiovascular disease, and it's often caused by an unhealthy diet, lack of exercise, being overweight and smoking. All of these are major risk factors for developing atherosclerosis and, in turn, cardiovascular disease Symptoms of heart disease in your blood vessels (cardiovascular disease) Cardiovascular disease is caused by narrowed, blocked or stiffened blood vessels that prevent your heart, brain or other parts of your body from receiving enough blood. Cardiovascular disease symptoms can include: * Chest pain (angina) * Shortness of breath * Pain, numbness, weakness or coldness in your legs or arms, if the blood vessels in those parts of your body are......

Health Promotion

...Promoting Schools model There is hope that improved health education for children will ultimately empower them to cope better in adulthood through correct and nutritionally balanced choices about their diet, whilst maintaining an active lifestyle and being connected with their community. Educating children in regards to health is not a choice, it is a necessity as outlined in the NSW primary curriculum as one of the key learning areas. The curriculum does not just focus on physical development and health in relation to obesity (even though as mentioned earlier this is a very major concern for Australian children) it incorporates “ all aspects of an individual’s wellbeing, inclusive of social, mental, physical and spiritual health.”( PDHPE K-6 Syllabus 1999 pp5) This is occurs through two strands, one with a focus on Physical development and Health and the other on Physical Education. There is a principal of best practice in relation to how settings facilitate this learning process that I will refer to in this paper as the HPS (Health Promoting Schools Model). If children’s needs were continuously met in regards to best practice of health education it would also connect children in some way to all of the key outcomes identified in Early Years Learning Framework (EYLF). The EYLF has been established as a guide to assist educators in providing our young children with the very best learning foundation that not only prepares them for future schooling but also enables......
