Cardiology Flashcards
What organs have resistance in series?
Liver and Kidneys
What organs have resistance in parallel?
All the rest of the organs (except liver and kidneys)
What organ has the highest AVO2 Difference at rest?
heart
What organ has the highest AVO2 difference after exercise?
Muscle
What organ has the highest AVO2 difference after a meal?
GI tract
What organ has the highest AVO2 difference during a test?
Brain
What organ has the lower AVO2 difference?
Kidney
Where does a Type A thoracic aortic dissection occur?
Ascending Aorta, (occurs in Cystic medial necrosis and Syphilis)
Where does a Type B thoracic aortic dissection occur?
Descending Aorta, (occurs in trauma and Atherosclerosis)
In what layers does a true aortic aneurysm occur?
Intima, media, and adventitia
In what layers does a pseudo aortic aneurysm occur?
Intima and media layers
What is pulse pressure?
Systolic minus diastolic pressure
What vessel has the thickest layer of smooth muscle?
Aorta
What vesels have the most smooth muscle?
Arterioles
What vessels have the largest cross-sectional area?
Capillaries
What vessel has the highest compliance?
Veins
What vessels have the highest capacitance?
Veins and Venules
What is your maximum heart rate?
220 minus the person’s age
What is stable angina?
Pain with exertion that is relieved with rest (Athersclerosis MCC)
What unstable angina?
Pain at rest (transient clots MCC)
What is Prinzmetal’s angina?
Coronary Artery Spasm
What is Amyloidosis and what stain is used?
Amyloid deposits that stain Congo red: Apple-Green Birefringence (AA-chronic disease)
What is hemochromatosis?
Iron deposits in organs
leads to hyperpigmentation, bronze diabetes, and arthritis
What is cardiac tamponade?
Pressure equalized in all 4 chambers, quiet Precordium, no pulse or BP, Kussmaul’s Sign, Pulsus Pardoxus (Decrease in BP greater than 10 mm Hg with inspiration)
What is transudate?
An effusion with mostly water
too much water: Heart or Renal failure
not enough protein: Cirrhosis (can’t make protein), and Nephrotic Syndrome (spilling out protein in urine)
What is exudate?
Effusion of mostly protein Too much protein: Will have --- Purulent (from Bacteria), Hemorrhagic (from trauma, CA, PE) Fibrinous (from collagen vascular disease), Granulomatous (non-bacterial)
What is systole?
Ejection of blood from the heart, Decreased blood flow to Coronary arteries, more extraction of Oxygen Phase 1 Korotkoff
What is diastole?
Heart ventricles filling
increased blood to Coronary arteries
less extraction of oxygen
Phase 4 and 5 Korotkoff
What are the only arteries with deoxygenated blood?
Pulmonary and umbilical arteries
What murmur has a water hammer pulse?
Aortic regurgitation
What murmur has Pulsus Tardus?
Aortic stenosis
