Case Study Investigations
Research Summary- The research found that Nancy has high levels of cholesterol, LDL, triglycerides and glucose. The research also found that both Nancy and Jim have healthy and unhealthy habits and that they are both at risk for heart disease, stroke and diabetes. We are specifically researching what could possibly be Nancy’s health issue as she has a backache and has been feeling tired lately.
Data Collected- The data collected is that Nancy has been having a backache, a burning sensation in her chest, feels nauseous, has trouble breathing and can not keep up with light exercise. Nancy has high levels of cholesterol, LDL, triglycerides and glucose. She has healthy habits such as regularly exercising and estrogen replacement therapy. But, her unhealthy habits include overeating and being overweight.
Angina equivalent symptoms are different from classic angina symptoms because women often have symptoms of coronary heart disease and heart attacks that are different from men’s. Nancy’s symptoms are common for women but different from the male symptoms, so they are called angina equivalent symptoms.
These symptoms are caused by coronary heart disease or are the warning signs of a heart attack.
Nancy’s symptoms lessen when she is resting because she is not having a heart attack. If she was having a heart attack, the symptoms would not subside with rest.
Before this case study I did not know that females and males have different symptoms for coronary heart disease or heart attack.
Medical researchers use case studies to find out if individuals of both sexes and from diverse racial and ethnic background have similar symptoms or react to the same treatment.
The purpose of the lab we did was to identify the conditions that need to stay constant in order to keep the body in equilibrium and how organisms maintain stable internal conditions while their external environment is changing.
The procedure of the lab was to have one person do jumping jacks for two minutes at a time, six minutes total.They would stop and sit down after every 2 minutes so we could record their body color, perspiration level, temperature, breathing rate, heart rate, blood pressure and oxygen saturation. After the six minutes or jumping jacks, the participant would rest for one minute. After this one minute had passed we would record their body color, perspiration level, temperature, breathing rate, heart rate, blood pressure and oxygen saturation.
The conclusion that we came to was that the longer the participant exercised for, the more pink her color became and perspiration level increased. Her breathing rate and oxygen saturation level stayed constant while her body temperature decreased and her heart rate and blood pressure increased. Her body temperature decreased because sweat cools down the body. Her heart rate and blood pressure increased while exercising but then returned to homeostasis after resting for one minute.
