Three major epicardial arteries
Left anterior descending
Left circumflex
Right coronary
LAD-supplies apex, anterior 2/3 septum, anterior wall of LV
LCA-supplies lateral wall of LV
RCA-Supplies posterior 1/3 of septum, posterior basal wall of LV, RV free wall
5 mechanisms of heart failure
Pump failure-most common. Inadequate contraction/relaxation
Obstruction-stenosis, htn
Regurgitation-valvular insufficiency
Conduction-non-uniform contraction
Disruption of circulatory system
CHF
2% of population
classified by L vs R, diastolic vs systolic, low vs high output, forward vs backward
systolic vs diastolic dysfunction
systolic-deterioration of myocardial contractility
diastolit-inability of heart to relax, expand and fill
hypertrophy patterns
concentric-reduction in diameter of cavity in HTN, aortic stenosis
Volume overlaod-dialation and hypertrophy
Left sided heart failure
damming of blood in pulmonary circulation and diminished peripheral blood pressure and flow
caused by ischemic heart diesase, HTN, atrial.mitral disease, non-ischemic myocardial disease
hypertrophy and idalation of LV, pulmonary congestion and edema, reduced renal perfusion, cerebral hypoxia
right sided heart failure
engorgement of systemic and portal venous sytems
caused by pul htn, cor-pulmonale, pul emboli
hypertrophy and dialation of RV, liver and portal congestion edema, kidney congestion, hypoxic encephalopathy, pleaural and pericardial effusion, peripheral edema
Systemic hypertensive heart disease
LV hypertrophy with no contributing cause, history of HTN
cardiomegaly, LA enlargement
Pulmonary hypertensive heart disease
Cor pulmonale-right ventricular hypertrophy and dialation
