Cardiomyopathy Flashcards
Three types of cardiomyopathy
Dilated, hypertrophic and restrictive
What is dilated cardiomyopathy
Where the ventricles stretches and thins, so dilates and can’t contract as well to pump blood
What is hypertrophic cardiomyopathy
Heart muscle becomes abnormally thick which makes it harder to pump blood from the heart. Left ventricular stiffness. mitral valve and cellular changes
What is restrictive cardiomyopathy
Rarest form - wall of ventricles are abnormally rigid and lack flexibility to expand and fill with blood.
Causes of dilated cardiomyopathy
Diabetes, obesity, arrhythmias, HTN, haemochromatosis, certain infections, alcohol, some cancer meds, certain toxin exposure and illegal drug use
Medications to help with dilated cardiomyopathy
ACEI, ARB, valsartan, beta blockers.
Diuretics, digoxin, ivabradine and anticoagulants
Therapies to help with dilated cardiomyopathy
Biventricular pacemaker, implantable cardiovreter-defib, left ventricular assist devices
Causes of hypertrophic cardiomyopathy
Gene mutations, high BP, ageing
Medications to help with hypertophic cardiomyopathy
Beta blockers, calcium channel blockers, amiodarone or disopyramide and blood thinners
Surgeries for hypertrophic cardiomyopathy
Septal myectomy, sebtal ablation, implantable cadioverter defib
Causes of restrictive cardiomyopathy
Build up of scar tissue or abnormal proteins, chemotherapy, radiation, haemochromatosis, sarcoidosis
Medications to help restrictive cardiomyopathy
Beta blockers, ACEI, digoxin, diuretics, aldosterone inhibitors, therapy for cause.
