Medical Surgical Cardiomyopathy #3

Question

Which medical condition(s) most likely contributed to a client’s diagnosis of secondary dilated cardiomyopathy? Select all that apply.

Answers

  1. History of rheumatic heart disease
    • Rationale:

      This answer is correct because a history of valvular disease related to rheumatic heart disease is a cause of dilated cardiomyopathy. In dilated cardiomyopathy, the left ventricle is dilated, enlarged, and unable to pump blood effectively. Other conditions implicated for increasing the risk of dilated cardiomyopathy include diabetes, thyroid disease, alcoholism, and exposure to certain toxins and drugs, such as cocaine, amphetamine, and some cancer drugs have been known to cause dilated cardiomyopathy.

  2. Benign prostatic hyperplasia
    • Rationale:

      This answer is not correct because benign prostatic hyperplasia is not a condition known to cause dilated cardiomyopathy. Conditions implicated for increasing the risk of dilated cardiomyopathy include valvular disease (e.g., rheumatic heart disease), diabetes, thyroid disease, alcoholism, and exposure to certain toxins and drugs, such as cocaine, amphetamine, and some cancer drugs have been known to cause dilated cardiomyopathy.

  3. Alprazolam addiction
    • Rationale:

      This answer is not correct because excessive alprazolam use or addiction is not a condition known to cause dilated cardiomyopathy. Conditions implicated for increasing the risk of dilated cardiomyopathy include valvular disease (e.g., rheumatic heart disease), diabetes, thyroid disease, alcoholism, and exposure to certain toxins and drugs, such as cocaine, amphetamine, and some cancer drugs have been known to cause dilated cardiomyopathy.

  4. Uncontrolled diabetes
    • Rationale:

      This answer is correct because a history of uncontrolled diabetes is a cause of dilated cardiomyopathy. In dilated cardiomyopathy, the left ventricle is dilated, enlarged, and unable to pump blood effectively. Other conditions implicated for increasing the risk of dilated cardiomyopathy include valvular disease (e.g., rheumatic heart disease), thyroid disease, alcoholism, and exposure to certain toxins and drugs, such as cocaine, amphetamine, and some cancer drugs have been known to cause dilated cardiomyopathy.

  5. Excessive alcohol intake
    • Rationale:

      This answer is correct because a history of excessive alcohol use or alcoholism is a cause of dilated cardiomyopathy. In dilated cardiomyopathy, the left ventricle is dilated, enlarged, and unable to pump blood effectively. Other conditions implicated for increasing the risk of dilated cardiomyopathy include valvular disease (e.g., rheumatic heart disease), diabetes, thyroid disease, and exposure to certain drugs, such as cocaine, amphetamine, and some cancer drugs have been known to cause dilated cardiomyopathy.

Overview

Secondary dilated cardiomyopathy can be caused by various conditions including valvular disease (e.g., rheumatic heart disease), uncontrolled diabetes, and excessive alcohol intake.

Explanation

Learning Outcomes

Dilated cardiomyopathy is the most common cardiomyopathy. In dilated cardiomyopathy, the left ventricle is dilated, enlarged, and unable to pump blood effectively. Secondary cardiomyopathy is cardiomyopathy caused by a medical condition. Conditions implicated for increasing the risk of dilated cardiomyopathy include valvular disease (e.g., rheumatic heart disease), diabetes, thyroid disease, alcoholism, and exposure to certain toxins and drugs, such as cocaine, amphetamine, and some cancer drugs have been known to cause dilated cardiomyopathy.

Test Taking Tip

In dilated cardiomyopathy, the left ventricle is dilated, enlarged, and unable to pump blood effectively. Secondary causes would be causes that would damage the heart in a way that would interfere with or weaken the ventricle’s pumping ability.
