PP Clues - Cardiology Flashcards
Organs with resistance in series
Liver and Kidney
Organs with resistance in parallel
Everything but liver and kidney
Organ with highest AV-O2 difference at rest
Heart
Organ with highest AV-O2 difference after exercise
Muscle
Organ with highest AV-O2 difference after a meal
GI
Organ with highest AV-O2 difference during an exam
Brain
Organ with the lowest AV-O2 difference
Kidney
Type A thoracic aortic dissection
Ascending aorta
Associated with cystic medial necrosis and syphilis
Type B thoracic aortic dissection
Descending aorta
Associated with trauma and atherosclerosis
Layers of a true aortic aneurysm
Intima, media, adventicia
Layers of a pseudo aortic aneurysm
Intima and media
Pulse Pressure
Systolic - Diastolic
Vessel with thickest layer of SM
Aorta
Vessels with the most SM
Arterioles
Vessels with the largest cross sectional area
Capillaries
Vessel with the highest compliance
Aorta
Vessels with the highest capacitance
Veins and venules
Max HR
220 - age
Stable Angina
Pain on exertion
Associated with atherosclerosis
Unstable Angina
Pain at rest
Associated with transient clots
Prinzmetal Angina
Intermittent pain at rest
Associated with coronary artery spasm
Stain to see Amyloidosis
Congo Red - apple green birefringence
Hemochomatosis
Iron deposition in organs
Hyperpigmentation, arthritis, DM
Cardiac Tamponade
Pressure equalized in all 4 chambers Quiet precordium No pulse or BP Kussmaul's sign Pulsus paradoxus (decreased systolic pressure > 10mmHg on inspiration)
Transudate
Effusion of mostly water
1 = Too much water (HF and renal failure)
2 = Not enough protein (cirrhosis and nephrotic syndrome)
Exudate
Effusion of mostly protein Purulent = bacteria Hemorrhagic = trauma, cancer, PE Fibrinous = collagen vascular disease, uremia, TB Granulomatous = non-bacterial
Systole
Ventricular contaction
Decrease in blood flow to the coronary arteries
Increased O2 extraction
Diastole
Ventricular relaxation
Increase in blood flow to coronary arteries
Decreased O2 extraction
Only arteries with deoxygenated blood
Pulmonary and Umbilical
Murmur with Waterhammer Pulse
Aortic Regurgitation
