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
