ASSESSING LIFESTYLE INTERVENTIONS TO IMPROVE CARDIOVASCULAR HEALTH USING AN AGENT-BASED MODEL ABSTRACT Cardiovascular disease (CVD) is the main reason for death in the United States (US) and spots a substantial monetary weight on the health care system. Perceiving the significance of CVD prevention, in recent years the American Heart Association (AHA) started to underline the need to expand consciousness of key risk elements of CVD and proposed another idea called ideal cardiovascular health. Taking into account this idea, we developed agent-based model that is intended to capture individual health progression and study new CVD-related population health results (diabetes, myocardial dead tissue, stroke and death) over a specified time period. …show more content…
2012). In this study, we develop an agent based model (ABM) based on the ideal cardiovascular health concept. Specifically, our model can produce a user specified population, catch the flow of every individual's health practices and elements, and report an arrangement of health results and mortality over a period skyline of interest. ABM is a base up modeling approach that has been connected to comprehend real- world frameworks in which the representation of practices of people is imperative and population interaction exists (Rahmandad and Sterman 2008; Siebers et al. 2010). By utilizing basic guidelines of behavior and action, ABM can be utilized to model social and health frameworks in a natural way that is speaking to policymakers (MacaI and North 2010). Despite the fact that ABM is still a moderately new displaying methodology, it has been connected to take care of complex issues in a few distinct trains, for example, financial matters, other sociologies and human services operations administration (Barnes, Golden, and Price 2013; Bruch and Atwell 2013; Fagiolo, Moneta, and Windrum 2007). An orderly writing audit in 2006 identified 42 CVD approach models and examined their …show more content…
When a man has a background marked by MI or stroke, he/she will have a higher danger of passing on because of CVD. Despite the fact that it is conceivable that a man has a past filled with both MI and stroke, we don't consider this situation in our model since it is vague how having a background marked by both diseases would change the death rate taking into account the distributed studies. In our model, "death" could be because of CVD or different reasons. The overall age and gender specific mortality rates for the general US population are acquired from the US key measurements information (Heron et al. 2009). The move probabilities from "history of MI" or "history of stroke" to "death" (i.e., mortality because of CVD) are ascertained taking into account the Framingham Risk Calculator (Anderson et al. 1991). The move probabilities from "no CVD history" to "death" (i.e., mortality because of different reasons) are then ascertained by subtracting the death rates because of CVD from the general death rates. Note that "death" is a retaining state and individuals in the "death" state are expelled from the

Strokes are commonly associated with old age, symptoms and awareness are often unnoticed in young adults due to ambiguity about strokes.
To illustrate this idea, an interesting fact is how there are more than one type of stroke. 85% of the time, a stroke would be caused by a blockage in the blood flow. The other 15% of the time will be from a haemorrhage, which is a blood clot. However, those aren't the only type. The ‘silent stroke’ is extremely difficult to predict as a silent stroke is a type of stroke that doesn't have many noticeable effects, but it causes the same amount of damage. They are quite common. With anyone who has experienced one, there is a high chance they’ll
Recently risk of CAD expanded to affects younger age causing serious consequences, so strategies to prevent CVDs should be applied (Mackay & Mensah 2004), (Sharma & Ganguly 2005).
From the data given we were able to construct table 3 where the Mean Mortality, Mortality Percentage and Probit were calculated.
included in the analysis. Time to event data will be based on death event and recurrence of tumor.
eligible for this act. With every disease other than cancer, it is virtually impossible to estimate life
Method: Based on the cohort study, the patients were followed for 8 years. The depended variable was determined gap times between recurrent events. The estimates, under the joint model of recurrent events risk and death of patient with spline functions, were determined. The analysis was done with R software.
Cardiovascular disease comprises the congestive heart failure, stroke, and coronary heart disease. These conditions have continued to be the major causes of morbidity and mortality in the United States of America today. The occurrence of cardiovascular diseases is influenced by various factors such as physical, political, environmental, and social factors (Kochanek, 2011). These factors entail access to quality and affordable health care services, affordability to healthy diets, conditions of work, physical exercises, community support, and access to education.
The causes of CVD can be seen through the sociocultural determinants (family, peers and media). These determinants of health priorities in Australia would have a great impact on people who would have a history of CVD. Also, people with cultural backgrounds, such as Aboriginal and Torres Strait Islander people, have a higher risk of CVD due to the fact of having a lower education status and a lower Socioeconomic Status (SES) . Individuals living in Middle Eastern countries would also have high rates in CVD due to their unhealthy diets such as eating foods with high amounts of saturated fats for e.g. oils. This means that the living conditions of an individual can determine the impact of one being affected with the
Atherosclerosis is commonly referred to as the principal cause of death in the developed world. Although deaths attributed to CVD have reduced significantly over the last 10 years, atherosclerosis is still one of the leading causes of mortality, both globally and in the UK. The World Health Organisation (2014) reports that CVD accounted for 17.5 million deaths in 2012. According to the Office for National Statistics (2013) circulatory diseases, including heart disease and strokes, were the cause of 28% of all deaths in England & Wales during the year 2013. Deaths due to atherosclerosis are expected to rise in the UK due to the rising elderly population and obesity epidemic, thus treatments that can reverse the atherosclerotic process will be of benefit to many millions of patients.
Cardiovascular disease (CVD) is a global epidemic (WHO 2016). In 2012, The World Health Organisation (2016) estimated that 17.5 million deaths were caused by cardiovascular related diseases. In Australia, 45,000 deaths occurred in 2014 (AIHW 2016) and 4,300 Tasmanian deaths in 2010 (Tasmania Medicare Local Limited 2012). The major risk factors for developing cardiovascular disease include, tobacco exposure, physical inactivity and consumption of foods high in artificial trans fats. (World Heart Federation 2017). Risks of developing the disease can also be non-modifiable, such as living situations. Individuals living in low socioeconomic areas have been studied to have a higher association with cardiovascular disease than those
My results overall connclude that when it comes to CVD people should do their part to stay healthy. People have to take charge and be in control of their own actions. Some CVD is preventable but first people have to be willing to partake in preventative measures such as cut out the use of tobacco, or drink in moderation, and elect to eat more healthly. Subtle and consistent changes is what makes the difference and helps ad to the continuity of life.
“Inadequate measures for preventing, detecting, and controlling risk factors lead to first CVD events (e.g., heart attack, heart failure, stroke) from which many victims die suddenly, while others survive with a high risk for recurrence and often with disability.” –CVD Action Plan
The case fatality ration was defined as the proportion of deaths over the new cases in a period. It is expressed as a percentage and represents the risk of the CM.
