Resource summary
Pathology - Heart Conditions Continued
Left Sided HF
Manifestated Relationships
Elevated filling (diastolic) pressures
dyspnea
insufficient cardiac output
Right sided HF
Causes
Overloaded LS Heart dysfunction (most common)
chronic RV pressure overload
Primary manifestations
elevated R atrial and systemic venous pressures
Renal dysfunction
Hypertensive Heart Disease (HHD)
Main cause
Increased demands on heart via hypertension --> pressure overload & ventricular hypertrophy
LS HHD
Most common, result of systemic Hypertension
RS HHD (cor pulmonale)
Annotations:
stems from pressure overload of right ventricle. charcterized by right ventricular hypertrophy and dilation.
Caused by pulmonary hypertension
Most commonly occurs as complication of LS HD
Morphology
Marked dilation of right V w/out hypertrophy (Acute)
thickening of R ventricular wall (chronic)
Morphology
Thickened ventricular wall
Impaired diastolic filling
Microscopic
increased in transverse diameter of myocytes (early stages)
cellular and nuclear enlargment, along/w interstitial fibrosis (late stages)
Valvular HD
