stable angina
Where do red (hemorrhagic) infarcts occur?
loose tissue w/ collaterals (e.g., lungs, intestine) or following reperfusion
Where do pale infarcts occur?
in solid tissues w/ single blood supply (e.g., brain, heart, kidney, spleen)

LV failure and pulmonary edema
cardiogenic shock
rupture of ventricular free wall, interventricular septum, papillary muscle, cardiac tamponade
thromboembolism - mural thrombus
fibrinous pericarditis (friction fub)
Dressler's syndrome (autoimmune pheenomenon resulting in fibrinous pericarditis)
What is the most common cardiomyopathy?
dilated (congestive) cardiomyopathy - 90%
What type of cardiomyopathy causes systolic dysfunction?
dilated (congestive) cardiomyopathy
What type of cardiomyopathy causes diastolic dysfunction?
hypertrophic cardiomyopathy
hypertrophic cardiomyopathy
walls of LV are thickened (esp. the ventricular septum) and chamber becomes banana shaped
cause of sudden death in young athletes
50% inheriited as autosomal dominant trait
characterized microscopically by disoriented and tangled myocardial fibers
dilated cardiomyopathy
most comon form of cardiomyopathy
characterized by dilation of both ventricles and by both right- and left-sided heart failure
restrictive cardiomyopathy
caused by infiltrative processes w/in myocardium that results in stiffening of the heart muscle -> interferes w/ pumping action
exemplified by cardiac amloidosis -> right- and left-sided heart failure
mitral regurgitation
holosystolic high-pitched "blowing murmur"
loudest at apex
aortic stenosis
crescendo-decrescendo systolic ejection murmur following ejection click
LV >> aortic pressure during systole
radiates to carotids/apex
holosystolic murmur
mitral prolapse
late systolic murmuc w/ midsystolic click
most frequent valvular lesion
aortic regurgitation
immediate high-pitched "blowing" diastolic murmur
wide pulse pressure
mitral stenosis
follows opening snap
delayed rumbling late diastolic murmur
LA >> LV pressure during diastole
patent ductus arteriosus
continusos machine-like murmur
loudest at time of S2
