|
Hypertensive heart disease |
related to effects in the heart related to increased afterload LV undergo hypertension |
|
|
Effects of LVH |
increased demand for O2 structural heart disease=risk for arrhythmia or SCD thickened ventricle not able to relax (S4) dilation via CHF occurs without correction |
|
|
valvular diseases |
stenosis=tight valve regurg=leaky backwards flow upstream hypertrophy |
|
|
Mitral stenosis |
rheumatic heart disease |
|
|
aortic stenosis |
senile calcific stenosis calcification of bicuspid valve |
|
|
mitral regurg |
LV dilation papillary muscle dysfunction rupture of chordae mitral valve prolapse |
|
|
aortic regurg |
aortic dilation (HTN, syph, marfan's, CTD)
|
|
|
Rheumatic heart disease |
sequala of rheumatic fever following strep pharyngitis inflammation of the layers of the heart mitral valve most common involved |
|
|
Aschoff body |
focus of fibrinoid necrosis surrounded by lymphocytes and macrophages |
|
|
verrucous endocarditis |
warty growths on free edges of valve leaflets |
|
|
Effects of mitral stenosis |
impedence of flow leads to back up and LA dilation |
|
|
Mitral regurg |
usually due to LV dilation and inability of leaflets to close |
|
|
Mitral valve prolapse |
ballooning of the valve into the left ventricle, mid systolic click |
|
|
aortic stenosis |
calcification due to senile (age) or bicuspid valve (abnormal number) |
|
|
endocarditis |
inner layer of the heart infection/inflammation |
|
|
nonbacterial thrombotic endocarditis |
hypercoaguable states aortic valve most normal |
|
|
infective endocarditis |
infection of the cardiac valves causing an adherent mass of fibrin inflammatory cells and bacteria |
|
|
acute bacterial endocarditis |
10-20% rapidly fatal s. aureus or other virulent organisms embolizations |
|
|
subacute bacterial endocarditis |
less virulent organisms (HACEK) previously abnormal valves slow, less severe |
|
|
prosthetic valve issues |
increased risk for endocarditis failure |
