## Cardiomyopathy: Part 1 ### Investigations * **ECG:** * Small voltage complexes in limb leads (chest leads: high voltage) * Sinus tachycardia (due to sympathetic overactivity) * Poor R wave progression * **Echo:** * Cardiomegaly * Large, roomy, thin walled left ventricle (↑ end-diastolic dimensions and ↓ ejection fraction) * Global hypokinesia * **MRI/Angiogram:** To rule out CAD in all, especially if presenting first time at age > 30 years. ### Treatment * Transplant ## Types of Cardiomyopathy (Based on Etiology) ### Peripartum Cardiomyopathy * Best prognosis among dilated cardiomyopathy * High recurrence risk * **Associations:** * Age at pregnancy (>30y) * Hypertension * **Time of presentation:** * Postpartum * Third trimester * **Pathology:** * SFLTI (Soluble fibrin-like tyrosine kinase 1: Anti-angiogenic factor) * **Clinical features:** * Left ventricular systolic failure features * Worsening dyspnea even with minimal exertion breastfeeding * Diaphoresis ### Advice * Avoid pregnancy again * Resolves in 3-4 months ### Note: * Angina with normal coronaries: * Myocarditis * Hypertrophic cardiomyopathy * Takotsubo cardiomyopathy
