Leading cause of heart transplant
Cardiomyopathy
What is the M:F affected by dilated cardiomyopathy?
3:1 male to female (M/C in african americans)
What is a risk factor for dilated cardiomyopathy?
Alcoholism
Type of cardiomyopathy that has a genetic correlation thus its progression can’t be slowed
Hypertrophic cardiomyopathy
This often follows an upper respiratory tract infection
Myocarditis
What is the M/C form of infectious myocarditis?
Viral myocarditis
Viral myocarditis is usually caused by what organism?
Coxsackie viruses
How is myocarditis treated?
Many cases resolve spontaneously, but may deteriorate & lead to dilated cardiomyopathy
How is endocarditis diagnosed?
Duke criteria: 2 major criteria or 1 major & 3 minor or 5 minor criteria
What are the Major Duke Criteria?
Typical micoorganisms identified
Persistently positive blood culture
Positive ECG
New valvular regurgitation murmur
What are the Minor Duke Criteria?
Predisposing condition Fever >100.4 (consistent) Blood Tests ECG suggestive but not positive Vascular Phenomenon
Symptoms assoc. w/ acute pericarditis?
Systemic symptoms of viral infection
Central chest pain radiating to either side of neck
Chest pain may be relieved by leaning forward
Friction rubs on ECG (pathoneumonic)
Symptoms assoc. w/ chronic pericarditis?
Painless (no chest pain)
Dyspnea & fatigue along w/ signs of L & R heart failure
What is the hallmark of chronic pericarditis?
Onset of dyspnea
This sign assoc. w/ chronic pericarditis is marked neck vein swelling during inspiration
Kusmal’s sign
What is the Classic Triad assoc. w/ pericarditis?
Raised jugular venous pressure
Pulsus paradoxis
Hypotension
What organisms cause pericarditis?
Coxsackievirus
Echovirus
What is the ddx assoc. w/ pericarditis?
Acute MI Dissection of thoracic aorta Pleurisy Musculoskeletal chest pain L & R ventricular failure
Type of aneursym assoc. w/ aortic valve disease & HTN
Aortic dissection
This type of aneurysm is M/C in the abdominal aorta
Non-dissecting (Dilatatory)
How is an abdominal aneurysm often diagnosed?
Incidental finding on abdominal radiograph
Disruption of the normal rhythm of the cardiac cycle is called what?
Cardiac arrhythmias
