Inferior vena cava obstruction - thrombus from femoral or iliac vein
Patient presents with painful subcutaneous red streaks that extend along lymphatics - diagnosis and whats common cause
Lymphangitis - common cause are group A beta hemolytic strep

Malignant tumors - metastasis


Postirradiation fibrosis

What are the causes of primary lymphedema
Simple congenital

Familial congenital

Lymphedema praecox
Reduced blood flow in _ the major artery in the thigh can cause leg pain with exercise (intermittent claudcation) and can lead to skin ulcers, gangrene and amputations
Femoropopliteal artery
Major cause (90%) of ischemic heart disease
Reduced coronary blood flow
4 clinical manifestations of IHD


Chronic IHD with heart failure

Sudden cardiac death
Diagnosis of chronic ischemic heart disease requires critical stenosis of
> 75%
Most MI, unstable angina and sudden cardiac death are precipitated by _
Plaque disruption with overlying thrombus
Factors causing inability of plaque to withstand mechanical stress


Hemorrhage into atheroma
What types of plaques are vulnerable to disrupt
Plaques with large amounts of foam cells and extracellular lipids and have thin fibrous cap
Where there is a greates stress on plaque and fibrous cap is thinnest
Junction of fibrous cap and normal adjacent arterial segment
What determines strength of plaque
Metalloproteinases are made by _
Macrophages in atheroma
Increases mechanical stress on plaque (influence)
Adrenergic stimulation
Most common cause of death in patients with MI and hemorrhage
Lethal arrhythmia
Cause of stable angina
Decreased coronary blood flow as result of chronic stenosis atherosclerosis
Patietn presents with complaint of chest pain that occurs with exercise, emotional stress or anything that increases heart work
Stable angina
Pain in stable angina is relieved by -
Nitroglycerin or rest
Patient presents with chest pain at rest - he states that is unrelated to his physical activity or increases in heart rate
Prinzmetal angina
Cause of Prinzmetal angina
Coronary vasospasm
What do you see on EKG of patient with Prinzmetal angina
ST elevation
What type of ischemia in Prinzmetal angina
Transmural ischemia
Treatment for prinzmetal angina
Ca channel blockers or nitroglycerine
Which test should NOT be done in patient with unstable angina
Treadmill test
What do you see on EKG of patient with unstable angina
ST depression
What type of ischemia in patient with unstable angina
Subendocardial ischemia
Patient presents with chest pain at rest that progressively getting longer -
Unstable crescendo angina
Cause for unstable angina
Plaque disruption - superimposed thrombus, vasospasm
Does unstable angina respond to any drugs
DOES NOT respons to Ca channel blockers or nitro
What type of necrosis is MI
This type of ischemia involves entire wall (full thickness) of myocardium - endocardium, midwall and epicardium, usually caused by atherosclerosis, plaque disruption, thrombus etc -->
Transmural ischemia
What do you see on EKG of transmural ischemia
ST elevation
Patient presents with sinus bradycardia and chest pain - which artery is responsible
This artery involves LV anterior free wal, apex and 2/3 of anterior septum
This artery supplies inferior/posterior wall of LV and RV and posterior 1/3 of septum and AV node
This artery supplies lateral wall of LV
Left circumflex
This type of ischemia occurs in least perfused area of heart, more vulnerable to ischemia - limited to 1/3 of myocardium
Subendocardial ischemia
What do you see on EKG of patient with subendocardial ischemia
Depression of ST segment
Autopsy of the heart reveals white collagenous scar -how old is infarct?
Over 2 months
Sequence of events in MI
Plaque disruption --> Platelet adhesion and aggregation --> Vasospasm --> Extrinsic coagulation pathway --> total occlusion of lumen
Reasons for non atherosclerotic induced MI
VASOSPASM - lethal arrhythmia

EMBOLI --> LV mural thrombus, LA, paradoxical
Coagulative necrosis occurs when after onset
4-12 hours
Effective way to salvage ischemic myocardium and prevent MI _
Reestablishing coronary blood flow (reperfusion)
