5. Results 5.1 Decision Trees Evaluating the Model In this case the model results include: Tables that provide information about the model. Tree diagram. Charts that provide an indication of model performance. Model prediction variables added to the active dataset. The tree diagram is a graphic representation of the tree model. This tree diagram shows that: Using the CHAID method, thal factor is the best predictor of heart disease. For the value 6 and 7 for thal, the next best predictor is ca and for the thal value 3 the next best predictor is age. If the value of ca is 1, 2 or 3 then thal and ca will be acts as the main factor of heart diseases. Since there are no child nodes below it, this is considered as a terminal node. In case if the value of ca is 0 or missing then age will be the next best predictor. For the age group less than or equal to 50 with thal value of 7 or 6, around 82% of patients are attacked in heart disease. For the age group greater than 50 around 21 percent are attacked in heart diseases. On the other hand if the minimum value of thal is 3 then age will be the next best predictor. For the age group less than or equal to 58 around 8.6% patient are attacked with heart diseases and for the age value greater than 58 around 44% are attacked with heart disease.

1. Which of the following clients is at a high risk for developing dilated cardiomyopathy?
rate for the individual with angina pectoris (sample 6). Explain how you might use this data to monitor heart conditions.
Figure 2 shows the relationship between the extent of LGE and SCE. Figure 2A shows that, compared to other groups, the cardiac health of patients with LGE ≥20% deteriorated more rapidly and had less freedom from SCD as the years progressed. The other LGE groups showed a similar pattern, but at a slower rate than the patients with LGE ≥20%. The rate of SCD events was followed by with LGE ≤15%, then LGE ≤10%, with absent LGE patients having the lowest rate of SCD events. Figure 2B shows the incidence of SCD events with different LGE percent groups. Again, the LGE ≥20% had the highest incidence of SCD events, followed by LGE 11-19%, and LGE ≤10%. 0 LGE had the lowest incidence of LGE.
The study population will consist of all adult patients aged 40-79 years during the period 1995-2015 in the CPRD. I will exclude all patients with a history of cancer (non-melanoma), VTE, cerebrovascular disease, coronary heart disease, heart failure, coagulopathies, vasculitis, and chronic kidney disease prior to cohort entry. Participants will be required to have at least one year of recorded history in the database before the study entry date. The date of entry into the cohort (start date) will be defined as the last of the date patients became 40 years old or 1995, and registered in the CPRD).
The method adopted was quantitative in nature, using a randomized controlled trial. In order to achieve this, 71 adult patients were assessed for eligibility and among this 59 met the given criteria. They were randomly categorized into treatment groups consisting of 29 patients and a control group consisting of 27 patients. The randomization was done by the same nurse who recruited the patients for
The purpose of this lab was to allow students to understand how to conduct/examine a questionnaire and, from the information, infer if they are at high, medium, or low risk for coronary heart disease. Also, to use the information gathered from the questionnaire to suggest ways to improve ones health through lifestyle changes such as diet, exercise, or quit smoking. Knowing how to conduct this questionnaire will allow a physician to obtain as much information about the patient for them to maximize the patient’s safety and to prevent them from coronary heart disease.
A vital signs report issued by the Centers for Disease Control and Prevention (CDC) today, announced that 3 out of 4 adults in America have a heart that is older than their actual age, putting them at a risk for heart attack and stroke. The heart’s age is calculated after profiling risk factors that affect the health of the cardiovascular system.
The purpose of this paper is to speak about statistical data of heart disease in Hartford Connecticut.
Mortality rate is very higher than the other age groups. compared with a young control group and this finding
Factor C: Tree stand (3 levels: Tree 1, Tree 2 and Tree 3). The experimental layout is presented in table 1 below.
There is a higher incidence rate for men ages 75-84. There is also a higher incidence rate for men ages 85-94. 66% of cardiovascular disease occurs in people of the age 75 and older. The leading cause of death in women over the age of 65 is heart disease. In 2005 cardiovascular disease in people greater than 65 was the underlying cause of death in 864,480 of the approx. 2.5 million total deaths in the U.S. This accounted for 82% of the deaths that year. After any kind of cardiovascular episode, all patients are at risk for disability and a possible repeat episode.
Due to the total number of people who suffer from FH around the world, I refined it to this group to keep the data concise for the sake of the project and to research on individuals that are more relevant to those suffering around me due to living in the United States. I believe that this sample size will provide enough information to answer the problem due to the increasing numbers of individuals who suffer from this disease along with the fact that having FH puts a person at a twenty times increased risk for heart disease than the general population, meaning that there will be quite a few studies providing research between the association of FH and CVD.^7 From this sample, there will be data missing for those outside of the age range, such as pediatric patients that were born with FH, or patients over the age of 65 with FH and other existing diseases. I believe it is better to use subjects in the middle of those age groups like listed above because their bodies will begin to display consequences of having the disease for numerous years, many of which living with it untreated or improperly treated, and this data may show the correlation between FH and CVD. If the person is older than age range, multiple other factors begin to be incorporated into the risk and presence of CVD from years of other stressors and diseases impacting their body, making it difficult to discern what impact FH
