MTB 2 CK - Cardio Flashcards
Normal splitting
S1 A2|P2 during inhalation (drop in intrathoracic pressure, increased venous return, longer pulmonary ejection time)
Wide splitting
S1 A2| |P2
Conditions that delay RV emptying (pulmonic stenosis, RBBB)
Exaggeration of normal
Fixed splitting
S1 A2| |P2
Seen in ASD (increased RV filling). Always there, similar to wide splitting…
Paradoxical splitting
S1 P2| |A2
Delayed LV emptying (aortic stenosis, LBBB)
P2 occurs before A2 which is abnormal.
On inhalation, P2 is prolonged, moves closer to A2, can be no splitting
(Maneuver and effect)
- Inhalation
- Exhalation
- Hand grip
- Valsalva
- Rapid squatting
- Increased right heart sounds
- Increased left heart sounds
- (increased SVR) Increased intensity of MR, AR, VSD, MVP murmurs (all things where flow is going backwards); decreases intensity of AS, HCOM (less fluid moving forwards to make a big sound)
- (decreased venous return/preload increases LV outflow obstruction) increases intensity of MVP and HCOM
- (increases venous return/preload) decreases HCOM
GI disorders associated with chest pain (4)
Ulcer disease
Cholelithiasis
Duodenitis
Gastritis
Around what age do the protective effects of estrogen wear off for women?
55-60yo
Pro ischemic pain qualities
soreness, dullness, squeezing, pressure-like pain
Anti-ischemic pain qualities
sharp, knifelike, lasting a few seconds
Fever + chest pain suggests
PE or pneumonia
Office chest pain days to weeks. Cardiac enzymes?
No
Office chest pain minutes to hours. Cardiac enzymes?
Yes
maximum HR equation
220-age
What if you can’t read the EKG? What test do you order
Thallium or sestamibi uptake scan.
Echo
Remember the difference in ischemia and infarction!
!
Holter monitor does not detect
ischemia (don’t do it for chest pain!!)
Holter monitor does detect
arrhythmia
Chronic angina meds (3)
Aspirin
B-blocker
Nitroglycerin
When to give Clopidogrel (CAD)
if aspirin intolerant (allergy)
w/ recent angioplasty w/ stenting
Prasugrel: don’t give to patients >75yo due to
risk of hemorrhagic stroke
Give ticlopidine if (CAD)
allergic to aspirin and clopidogrel (but not bc of bleeding!)
Ticlopidine adverse effects
neutropenia, TTP
When to give statins for CAD
LDL >100
What do you need to check regularly in a patient on a statin?
AST/ALT
Liver dysfunction MC adverse effect
Niacin adverse effects
glucose, uric acid, itchy
fibric acid adverse effects
myositis with statins
ezetimibe adverse effects
well tolerated but useless
CCB in CAD
may increase mortality by raising HR
When to use CCB in CAD
- Severe asthma
- Prinzmetal angina
- Cocaine-induced angina (B-blocker CI)
Adverse effects of CCB
- Edema
- Constipation
- Heart block (rare)
PCI vs. med mgmt in chronic angina
medical mgmt is better
Don’t use PCI for…
stable patients
Heart sound associated with acute coronary syndrome
S4
Kussmaul sign
increase in JVP on inhalation
–constrictive pericarditis, restrictive cardiomyopathy
continuous machine like murmur
PDA
Which is worse MI in V2-V4 or MI in II, III, aVF?
V2-V4–this is anterior wall. Higher mortality than inferior wall (II, III, aVF)
Pathologic potential of first degree AV block?
Very little
Should you treat PVCs?
Nope
Leads V1 and V2 should be read…
backwards (ST elevation is actually depression and depression is actually elevation) because they are posterior leads
O2, NG, aspirin, morphine–which to give first in acute MI?
Aspirin. The only one that lowers mortality
