Q

Etiology of dilated cardiomyopathy

A

Idiopathic, alcoholism (thiamine deficiency), genetics, myocarditis, chemo (doxorubicin), cocaine, heroin, glue sniffing, peripartum (last trimester or within 6 mo PP)

Q

Clinical features of dilated cardiomyopathy

A
  • Massive enlargement of heart with all chambers dilated
  • Mitral & tricuspid valve regurgitation
  • L and R sided S3 and S4 sounds
  • Narrow pulse pressure due to decreased stroke vol
  • Arrythmias (block in bundle of His, leading to atrial and ventricular arrythmias)
  • **Sudden death **

Q

Etiology of hypertrophic cardiomyopathy

A

Q

Clinical features of hypertrophic cardiomyopathy

A
  • Palpitations
  • Dizziness
  • Angina w exercise
  • SOB/DOE, CHF, arrhythmias
  • Split S2, S4, harsh systolic ejection (crescendo-decrescendo) murmur best hear along lower L sternal border or apex
  • Murmur best heard during valsalva
  • Palpable souble apical impulse

Q

Clinical features of restrictive cardiomyopathy

A
  • Worsening SOB
  • Progressive exercise intolerance
  • Fatigue
  • CHF w normal L ventricular systolic function
  • Arrhythmias
  • Elevated JVP
  • Loud early diastolic filling sounds (S3) may be present
  • Murmurs due to mitral and tricuspid regurg may be heard, but are secondary to the disease

Q

Investigations of cardiomyopathy (all 3)

A
  1. Dilated: CBC, electrolytes, BNP, troponin, CK, CK-MB, nonspecific ST-T and Q wave changes, CXR (enlarged heart, plural effusion).
  2. Hypertrophic: Prominent Q wave, short PR, 2D echocardiography is diagnostic, cardiac MRI to assess severity.
  3. Restrictive: Normal ECG or nonsepcific ST-T wave changes, low QRS volatage, CXR mild cardiac enlargement, ventricular biopsy can determine etiology
