Stable Angina
Pain on exertionAssociated with atherosclerosis
Unstable Angina

Intermittent pain at restAssociated with coronary artery spasm
Stain to see Amyloidosis
Congo Red - apple green birefringence
Hemochomatosis
Iron deposition in organsHyperpigmentation, arthritis, DM
Cardiac Tamponade
Pressure equalized in all 4 chambersQuiet precordiumNo pulse or BPKussmaul’s signPulsus paradoxus (decreased systolic pressure > 10mmHg on inspiration)
Transudate
Effusion of mostly water1 = Too much water (HF and renal failure)2 = Not enough protein (cirrhosis and nephrotic syndrome)
Exudate
Effusion of mostly protein Purulent = bacteriaHemorrhagic = trauma, cancer, PEFibrinous = collagen vascular disease, uremia, TBGranulomatous = non-bacterial
Systole
Ventricular contactionDecrease in blood flow to the coronary arteriesIncreased O2 extraction
Diastole
Ventricular relaxationIncrease in blood flow to coronary arteriesDecreased O2 extraction
Only arteries with deoxygenated blood
