1
Q

List the categories of causes of dilated cardiomyopathy.

A
  • Ischemic
  • Drug-induced (dauxirubicin)
  • Idiopathic
  • Wet beriberi
  • Alcohol
2
Q

How do patients with dilated cardiomyopathy present?

A

Because of the decreased contractility, those with DCM typically have symptoms similar to CHF: orthopnea, PND, JVD, DOE, pulmonary edema.

3
Q

Dilated cardiomyopathy should be treated with what?

A
  • CHF treatment: diuretics, oxygen, positioning, beta-blockers, ACE inhibitors, spironolactone
  • Alcohol avoidance
  • No chemotherapy
  • Heart transplant
4
Q

Why are beta-blockers part of the treatment for HOCM?

A

The aortic outlet gets obstructed in HOCM when the preload drops (because the ventricle is smaller and more likely to pinch off the aorta). Giving beta-blockers slows the heart rate and increases filling.

5
Q

Other than beta-blockers, list the treatment protocol for HOCM.

A
  • Diltiazem and verapamil (if they can’t tolerate BBs)
  • Cardiac defibrillator
  • Alcohol oblation (for poor surgical candidates)
  • Myomectomy
6
Q

_____________ should be screened for HOCM with an echocardiogram.

A

Relatives of someone with documented HOCM

7
Q

Concentric hypertrophy is usually caused by _______________.

A

longstanding HTN

8
Q

The three main causes of restrictive cardiomyopathy are _________________.

A

amyloidosis, sarcoidosis, and hemochromatosis

9
Q

If the test wants you to diagnose amyloidosis, they’ll likely tell you the patient has what other symptom?

A

Neuropathy

10
Q

How do the treatments of restrictive and diastolic cardiomyopathies differ from systolic cardiomyopathy?

A
  • In systolic cardiomyopathy, you diurese to avoid volume overload.
  • In diastolic cardiomyopathy and restrictive cardiomyopathy, you do not diurese (or you diurese only to the minimum amount necessary to relieve pulmonary edema).
