|
Most patients with cardiomyopathies will present with what?
|
Heart Failure
|
|
|
Dilated Cardiomyopathy
|
Big heart with big cavity contracting poorly
Poor DIFFUSE systolic function Genetic ALWAYS Enlargement of all 4 cardiac chambers--proportion of size of cavity to thickness of walls Myocyte hypertrophy interspersed with degeneration and atrophy Neurohormonal activation(symp and RAA) Hepatomegaly |
|
|
What is mitral regurgitation and in what condition does it often happen?
|
Dilated Cardiomyopathy--leaflets of mitral valve can't contract and there is slippage--upon contraction some blood will flow back to the LA
|
|
|
A big LV = ?
|
Mitral valve regurgitation
|
|
|
BNP is often seen in what patients?
|
Dilated CM
|
|
|
What is alcoholic CM?
|
Alcohol inhibits mitoch. ox/phos and fatty oxidation in the heart--Holiday Heart Syndrome
|
|
|
What is peripartum CM? What happens?
|
Cardiac Dilatation and CHF developing around and after delivery--bed rest recovery, advanced CM later in life, or progressive heart failure
|
|
|
If someone has peripartum CM then what?
|
Further pregnancies should be completely avoided
|
|
|
What is ARVD?
|
Arrhythmogenic Right Ventricular Dysplasia--portions of RV myocardium are replaced with adipose and fibrosis
|
|
|
Chagas Disease
|
T. Cruzi causes heart disease in central America--autoimmune reaction to trypanosome that causes the problem--RBBB and Left Anterior Hemiblock--not diffuse(posterior wall and apical contractility)
|
|
|
A young athlete dies suddenly--what type of CM? Where does it occur? What is common in all cases of this CM type?
|
Hypertrophic CM--occurs in septum and LV free wall--ALL HAVE GENETIC COMPONENT that encode for contractile proteins
|
|
|
How does hypertensive CM present?
|
Myocardial fibers show extensive disarray with intervening fibrosis
|
|
|
With one type of CM, increased flow to the heart is alleviating. In the other it worsens the condition.
|
Alleviating--Hypertrophic CM
Worsening--Dilated CM |
|
|
Restrictive Cardiomyopathy
|
Abnormally rigid ventricles with impaired diastolic function but normal systolic function--infiltration of the myocardium or hypertrophy are the underlying causes
|
|
|
What hypertrophy should you always biopsy?
|
Restrictive
|
|
|
What is Kussmaul's sign and what hypertrophy is indicated?
|
Upon Inspiration--jugular venous pressure does not fall and might increase because more blood is being brought to the veins but cannot enter the heart--indicates Restrictive CM
|
|
|
What causes Myocarditis?
|
Drug hypersense, radiation, or virus
|
|
|
What immune mediated injury to the heart is caused by coxsackievirus?
|
Myocarditis
|
|
|
What syndrome is stress induced CM?
|
Takotsubo--POSTMENOPAUSAL WOMEN and they recover--there is no enzymatic sign of problems
|
|
|
What should never be given to Takotsubo patients?
|
Thrombolytics
|
