- Post- thrombotic Syndrome -
ulceration and infection
- Thrombus
- Virchow's Triad

- Chronic Venous Insufficiency
- Superior Vena Cava Syndrome
(SVCS)

- Peripheral vascular
diseases
- Thromboangitis
obliterans aka Buerger
Disease
- inflammation --> necrotizing
- Raynaud
Phenomenon and
Disease
- vasospasm of the
hands
- Peripheral Artery Disease (PAD)
- Atherosclerosis
- Pathophysiology: Inflammatory
mechanisms in the setting up of
dyslipidemia--> atherosclerosis
1. Endothelial injury &
dysfunction; 2. Fatty Streak; 3.
Fibrotic Plaque; 4. Complicated
lesion/ plaque
- Coronary Artery Disease (CAD)
- CAN LEAD TO.....
- Reversible myocardial ischemia
- Stable Angina
- Acute Coronary Syndrome (ACS)
- Unstable Angina
- MYOCARDIAL INFARCTION
- STEMI
- Thrombus lodges permanently;
Infarction extends through myocardial
wall; ST segment elevation; Highest risk
for serious complications
- Non- STEMI
- Thomrbus may have broken up
before significant distal necrosis
occurred; subendocardial; usually ST
depression and T wave inversion;
recurrent thrombus formation on
plaque likely to occur w/o intervention
- Congesitve Heart Failure
- GENERAL: Increased diastolic
(filllling) pressures or inc. diastolic
volume. Not enough getting out.
Risk factors: CAD, HTN (high
afterload, vasoconstricted)
- Left sided heart failure
- SYSTOLIC
- decreased ejection fraction- (normal ejection is
50-75%) this is because there is dec.
contractility - causes inc. preload and inc.
afterload i- which causes dec. contractility -
viscious cycle
- DIASTOLIC
- dec. filling of the LV - Why would this happen?
Ventricle is stiff - dec. compliance, doesn't stretch
well (due to HTN, remodeling, cardiomyopathy), so
it doesn't fill well. leads to dec. preload. this may
be OK at rest but when you exercise your heart
won't be able to handle it
- SEQUELAE _ blood backs up, causes blood to back up into the
lungs - Pulmonary Edema; stasis of bllodd in left chamber
because it's not pumping well; inadequate perfusion of tissues
- Right sided heart failure
- LEFT SIDED FAILURE
- COR PULMOARE
- SEQUELAE - fluid backup in the
body
- Dysrhythmias
- ATRIAL
- SINUS
- VENTRICULAR
- AV
BLOCK
- Disorders of the Heart Wall
- Pericardum
- Acute
pericarditis
- Idiopathic
- Pericardial
effusion
- Accumulation of
pressure in right heart
- Constrictive
pericarditis
- TB, cancer radiation, cardiac
surgery - calcification and scarring
- Myocardium:
Cardiomyopathies
- Dilated
- Hypertrophic
- Restrictive
- Endocaridum
- Vallvular
Dysfunction
- Stenosis or Flapping in the Wind;
both stenosis and regurgitation lead
to inc. workload
- Rheumatic
Disease
- Infective
Endocarditis
