Week 4 discussion

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.

By Day 3

Post 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.

By Day 6

Respond 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.
