Veins and arteries are vital elements of the cardiovascular system.

Cardiovascular Disorders

Veins and arteries are vital elements of the cardiovascular system. They carry the blood supply through the body and are essential for proper function. Sometimes veins and arteries malfunction, resulting in cardiovascular disorders. Malfunctions of arteries and veins are similar to malfunctions of a water hose. Consider the structure and function of a hose. A tap releases water, which then travels through the hose and comes out the other end. If the hose has been dormant for several months, dirt and rusty particles might build up inside, resulting in a restricted flow of water. Similarly, buildup of plaque inside the coronary arteries restricts blood flow and leads to disorders such as coronary heart disease. This disease is one of the most common cardiovascular disorders, and according to the National Heart, Lung and Blood Institute (2011), is the leading cause of death for men and women in the United States. In this Discussion, you examine the pathophysiology of cardiovascular disorders such as coronary heart disease.

To prepare:

  • Review this week’s media presentation on alterations of cardiovascular functions, as well as Chapter 23 in the Huether and McCance text. Identify the pathophysiology of cardiovascular disorders.
  • Select one patient factor: genetics, gender, ethnicity, age, or behavior. Consider how the factor you selected might impact the pathophysiology of cardiovascular disorders.
  • Select one of the following alterations of cardiovascular disorders: peripheral arterial disease, myocardial infarction, coronary artery disease, congestive heart failure, or dysrhythmia. Think about how hypertension or dyslipidemia can lead to the alteration you selected.

Post on or before Day 3 a description of the pathophysiology of cardiovascular disorders, including how the factor you selected might impact the pathophysiology. Then, explain how hypertension or dyslipidemia can lead to the alteration you selected for patients with the factor you identified.

Read a selection of your colleagues’ responses.

Respond on or before Day 6 to at least two of your colleagues on two different days who selected different alterations and factors than you, in one or more of the following ways:

  • Share insights on how the factor you selected impacts the cardiovascular alteration your colleague selected.
  • Offer and support an alternative perspective using readings from the classroom or from your own research in the Walden Library.
  • Validate an idea with your own experience and additional research.
