PHA 1500 Module 4 Assignment Coronary Artery Disease

artery disease is a common type of heart disease and the leading cause of death
among both men and women in the United States. In this assignment, you will
explore this disease in more detail using the scenario below.


One of your
aging relatives is sedentary and smokes cigarettes. Out of concern for his
health, you decide to research more about this disease.

To complete
this assignment, do the following:

this disease using a minimum of 2 sources. You can use your textbook for one of
the sources. Choose the remaining source(s) from the GALE Virtual Reference
Library provided on the Structure and Function of the Human Body library guide

In a
minimum of 2 pages (not counting the references page), address the following:

Explain how
coronary artery disease develops in the human body.

the ways that your relative can prevent the onset of this disease.

what treatment options exist if steps to prevent the disease fail.

Include a
references page at the end of your document, formatted using the APA
guidelines, that lists your research sources.

Coronary artery disease (CAD) is the most common type of heart disease in the United States. It is sometimes called coronary heart disease or ischemic heart disease.

For some people, the first sign of CAD is a heart attack. You and your health care team may be able to help reduce your risk for CAD.

What causes coronary artery disease?

CAD is caused by plaque buildup in the walls of the arteries that supply blood to the heart (called coronary arteries) and other parts of the body.

Plaque is made up of deposits of cholesterol and other substances in the artery. Plaque buildup causes the inside of the arteries to narrow over time, which can partially or totally block the blood flow. This process is called atherosclerosis.

What are the symptoms of coronary artery disease?

Angina, or chest pain and discomfort, is the most common symptom of CAD. Angina can happen when too much plaque builds up inside arteries, causing them to narrow. Narrowed arteries can cause chest pain because they can block blood flow to your heart muscle and the rest of your body.

For many people, the first clue that they have CAD is a heart attack. Symptoms of heart attack include

Over time, CAD can weaken the heart muscle. This may lead to heart failure, a serious condition where the heart can’t pump blood the way it should.

Learn the facts about heart disease, including coronary artery disease, the most common type of heart disease.

What are the risks for coronary artery disease?

Overweight, physical inactivity, unhealthy eating, and smoking tobacco are risk factors for CAD. A family history of heart disease also increases your risk for CAD, especially a family history of having heart disease at an early age (50 or younger).

To find out your risk for CAD, your health care team may measure your blood pressure, blood cholesterol, and blood sugar levels.

Learn more about heart disease risk factors.

How is coronary artery disease diagnosed?

If you’re at high risk for heart disease or already have symptoms, your doctor can use several tests to diagnose CAD.

Heart tests and what they do.
Test What it Does
ECG or EKG (electrocardiogram) Measures the electrical activity, rate, and regularity of your heartbeat.
Echocardiogram Uses ultrasound (special sound wave) to create a picture of the heart.
Exercise stress test Measures your heart rate while you walk on a treadmill. This helps to determine how well your heart is working when it has to pump more blood.
Chest X-ray Uses x-rays to create a picture of the heart, lungs, and other organs in the chest.
Cardiac catheterization Checks the inside of your arteries for blockage by inserting a thin, flexible tube through an artery in the groin, arm, or neck to reach the heart. Health care professionals can measure blood pressure within the heart and the strength of blood flow through the heart’s chambers as well as collect blood samples from the heart or inject dye into the arteries of the heart (coronary arteries).
Coronary angiogram Monitors blockage and flow of blood through the coronary arteries. Uses X-rays to detect dye injected via cardiac catheterization.
Coronary artery calcium scan A computed tomography (CT) scan that looks in the coronary arteries for calcium buildup and plaque.

What is cardiac rehabilitation and recovery?

Cardiac rehabilitation (rehab) is an important program for anyone recovering from a heart attack, heart failure, or other heart problem that required surgery or medical care. In these people, cardiac rehab can help improve quality of life and can help prevent another cardiac event. Cardiac rehab is a supervised program that includes

  • Physical activity
  • Education about healthy living, including healthy eating, taking medicine as prescribed, and ways to help you quit smoking
  • Counseling to find ways to relieve stress and improve mental health

A team of people may help you through cardiac rehab, including your health care team, exercise and nutrition specialists, physical therapists, and counselors or mental health professionals.

How can I be healthier if I have coronary artery disease?

If you have CAD, your health care team may suggest the following steps to help lower your risk for heart attack or worsening heart disease:

  • Lifestyle changes, such as eating a healthier (lower sodium, lower fat) diet, increasing physical activity, reaching a healthy weight, and quitting smoking
  • Medicines to treat risk factors for CAD, such as high cholesterol, high blood pressure, or an irregular heartbeat
  • Surgical procedures to help restore blood flow to the heart
