What vessels have the most smooth muscle?
Arterioles
What vessels have the largest cross-sectional area?
Capilaries
What vessel has the highest compliance?
Aorta
What vessels have the highest capacitance?
Veins and venules
What is your max heart rate?
220
What is stable angina?
Pain w exertion (atherosclerosis)- 70% occluded, subendocardial ischemia
What is unstable angina?
Pain at rest (transient clots)- 90% occluded, transmural ischemia
What is Prinzemetal’s angina?
Intermittent pain (coronary artery spasm)
What is amyloidosis?
Stains Congo Red, Echo-apple green birefringence
What is Hemochromatosis?
Fe deposits in organs> Hyperpigmentation, arthritis, DM. Prussian blue stain
What is cardiac tamponade?
Beck’s triad: distant heart sounds, JVD, hypotension. Pressure equalized in all 4 chambers, distant heart sounds, no pulse or BP, Kussmaul sign, pulsus paradoxus (decreases > 10mmHg w/inspiration.
What is a transudate?
An effusion w/ mostly water.
Too much water: Heart failure, renal failure.
Not enough protein: Cirrhosis, Nephrotic syndrome (pee protein out).
What is an exudate?
An effusion w mostly proteins.
Too much protein: Purulent (bacteria), Hemorrhagic (trauma, cancer, PE), Fibrinous (collagen vascular dz, uremia, TB), granulomatous (non-bacterial).
What is systole?
Heart contract, decreases blood to the coronary arteries, more O2 extraction in the coronary vessels.
What is diastole?
Filling the heart, increases blood flow to the coronary arteries, less extraction of O2 in the coronaries.
What are the only arteries w deoxygenated blood?
Pulmonary and umbilical arteries.

A fib
What murmur has irregularly regular pulse?
PVC
What sound radiates to the neck?
AS
What sound radiates to the axilla?
MR
What sound radiates to the back?
PS
What disease has a boot shaped x-ray?
Right ventricular hypertrophy.
What disease has a banana shaped x-ray?
IHSS
What disease has an egg shaped x-ray?
Transposition of the great vessels?
What disease has a snowman shaped x-ray?
Total anomalous pulmonary venous return
What disease has a “3” shaped x-ray?
Coarctation of the aorta.
What is Osler Webber Rendu?
AVM in lung, gut, CNS> sequester platelets>talengectasias.
