cardiomyopathy Flashcards
Define cardiomyopathy
disease of the heart muscle that may become enlarged, thick, or ridgid
Define dialated cardiomyopathy
Dilation and impaired contraction of one or both ventricles, with cardiac enlargement and decreased EF
Common causes of dilated cardiomyopathy
viral, genetic (25-35%), ischemia/MI, valvular heart disease and HTN
Clinical presentation of dilated cardiomyopathy
SOB, Orthopnea, progressive exertional dyspnea, peripheral edema, vague cp, S3 or S4,
Common heart murmur of dialted cardiomyopathy
mitral/tricuspid regurg
Diagnosis of Dilated Cardiomyopathy
Echocardiogram
Treatment of dilated cardiomyopathy
Cessation of alcohol if diagnosed early. Beta blockers, ace, diuretics, dig, ICD, heart transplant (if dont recover)
Define HCM
genetic hypertrophy of the LV and obstruction of LV outflow
what is someone with HCM at increased risk for
Sudden death
Murmur of HCM
harsh crescendo-decrescendo systolic murmur that will develpo as obstruction worsens. Increases with valsalva
Aortic stenosis
Harsh cresceno-decrescendo systolic murmur that will decrease with valsalva
EKG finding of HCM
LVH and Different T wave morphologies
Diagnosis of HCM
Echo- LV wall thickness>15mm, mitral regurg, and LV outflow tract obstruction
Treatment of HCM
Medication- BB, ND-CCB.
ICD for syncope, sustained SVT and high risk
Surgery for severely symptomatic pts
Define restrictive cardiomyopathy
Non-dilated ventricle with normal wall thickness, but is ridgid and has severe diastolic dysfunction, and enlargment of both atria
