Patient 1: Steven

4. Based on the image of Steven’s arteries, what can you determine about his health? Are there indications of a particular risk? Explain your conclusions.
He is showing signs of shortness of breath, decreased lung capacity, chest pain. Steven seems to be experiencing early warning signs of a heart attack/heart disease. Based on scans of Steven’s arteries, he has large amounts of plaque buildup which restricts blood flow to the heart muscle.

5. Which of his lab values next to his image results would help indicate this risk? Explain.
His cholesterol and triglycerides are extremely higher than normal levels

6. What did the final image of Steven indicate? This image is an X-ray of his lungs. His lungs are constricted due to lack of blood flow. Also his weight and pressure on the lungs has contributed to the shortness of breath. Because his body mass is large, his heart has to work twice as hard to circulate blood and with blockage I the arteries, he is experiencing symptoms that indicate his body is not functioning correctly.

7. Name 2 possible treatments for what you found in the second image.
Proper blood flow needs to be restored to the heart. Two treatments to accomplish this is thrombolytic therapy which is also known as clot busing therapy or a minimally invasive therapy called angioplasty.
