| ==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== |
| ===Background===
| | {{Template:Cardiomyopathy DDX}} |
| *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
