-==Dilated Cardiomyopathy==
+==Background==
-===Background===
+*Disease of heart muscle
-*Idiopathic form accounts for 25% of CHF
-===Diagnosis===
-*CHF symptoms
-*CXR
-**Cardiomegaly, pulm venous htn
-*ECG
-**LV hypertrophy, poor R wave progression
-===Treatment===
-*Similar to CHF exacerbation
-*Ensure exacerbation not due to ischemia
-==Hypertrophic Cardiomyopathy==
+==Differential Diagnosis==

-*"HOCM"
-*Abnormal LV diastolic function due to decr compliance
-===Diagnosis===
-*Exertional dyspnea, chest pain, syncope
-*Systolic murmur that increases w/ valsalva
-*ECG
-**LV hypertrophy, deep Qs in 1, avL, V5-6 (daggers of death)
-===Treatment===
-*If decompensated presents as hypotensive CHF
-**Preserve preload
-***Careful hydration
-***Avoid high airway pressure if intubate
-**Limit tachycardia
-***Beta blockers
-**Avoid vasodilators (no nitrates)
-**Maintain sinus rythm (i.e. cardiovert A. fib)
-**Increase afterload (hypotensive only)
-***Phenylephrine
-==Restrictive Cardiomyopathy==
-===Background===
-*Must distinguish from constrictive pericarditis
-===Diagnosis===
-*Consider if CHF but no e/o cardiomegaly or systolic dysfunction
