Cardio Flashcards
these can be heard in mitral stenosis, except for
a) apical holosystolic murmur radiating o the axilla
b) low freq apical diastolic murmur
c) opening snap
d) loud first heart sound
a) apical holosystolic murmur radiating o the axilla
holosystolic radiating to axilla is typical of mitral regurgitation
Part of the therapy of decompensated heart failure, except for
a) mineralocorticoid-antagonists
b) diuretics
c) digoxin
d) parenteral volume expansion
e) ACE inhibitors
d) parenteral volume expansion
in chr decomp HF the body is in a state of fluid overload so diuretics and mineralocorticoid antagonists are essential. Digoxin should be given bc its a positive inotrope and negative chronotrope while ACEIs help long term survival. parenteral fluids (aka infusions) should be avoided
Cause of acute LVF, except for
a) bronchial asthma
b) AMI
c) hypertensive crisis
d) severe aortic stenosis
asthma bronchial
bronchial asthma puts strain on the RV not the L
Characteristic of hypertrophic obstructive cardiomyopathy, except for
a) might be combo with mitral insufficiency
b) digoxin is important in the early stage
c) it often shows a familial distribution
d) diastolic dysfunction is common
e) syncope is a common symptom
digoxin is important in the early stages
it is not recommended in either early or late stages unless the disease has reached its ‘burnout’ dilated phase
features of atrial myxoma, except for
a) the most common form of primary cardiac tumors
b) can be diagnosed with echo
c) often metastatic
d) can mimic mitral stenosis during physical exam
it’s often metastatic
since it’s benign and in situ, mets are rare
which one is true about the mechanism of action of digoxin
a) inhibits intracellular Na/K-ATPase
b) it lowers intracellular Na conc
c) inc ATP levels
d) enhances cAMP production
e) dec Ca release from sarcoplasmic reticulum
it inhibits the Na/K ATPase
this causes a temp rise in intracellular Na levels which inc intracellular Ca via the Na-Ca exchanger. As result the high Ca level inc myocardium contractility and has positive inotropic effect
All of the following statements about NTG are true, except for
a) inc intracellular cGMP levels
b) primarily metabolised in the liver
c) can induce significant reflex tachycardia
d) significantly prolongs AV conduction
e) can lead to postural hypotension
significantly prolongs AV conduction
nitrates don’t alter AV conduction
the typical side effect of nitrates are
a) HTN
b) headache
c) bradycardia
d) sexual dysfunction
e) anemia
headache
should resolve in a few days so they shouldn’t give up on it right away
The typical features of Prinzmetal angina
a) ST segment depression during angina
b) negative T waves during angina
c) pathologic Q waves during angina
d) elevated necroenzymes
e) ST segment elevation during angina
ST segment elevation during angina
Prnzmtl is a type of coronary artery spasm with ST elevation indicating subepi or transmural ischemia. ST depression is seen in subendocardial ischemia.
Types of unstable angina pectoris, except for
a) angina at rest
b) crescendo angina
c) effort angina
d) new onset angina
effort angina
new onset counts as unstable, and crescendo too (inc in freq, severity, and duration), and can dev at rest. effort means it’s the same level of stress that causes it each time
The most common pathology of MI
a) coronary embolism
b) rupture of an ATH plaque
c) dissection of coronary walls
d) growing of ATh plaque
e) coronary inflamm
rupture of ATH plaque
it’s usually the rupture of the plaque the following thrombus. soft plaques are usually worse
normal mean electrical axis in the front plane, except for
a) +60
b) +90
c) -45
d) 0
e) +45
-45
0 to +90 is thought to be normal range while -45 is LAD
if AMI is suspected, the following diagnostic procedures should be carried out except for
a) ECG
b) blood test to see CK-MB and troponin
c) physical exam
d) cardiac stress test
e) echo
cardiac stress test
don’t do it stupid they’re already stressed
IHD can present with , except for
a) AMI
b) stable angina
c) DVT
d) sudden cardiac death
e) ischemic cardiomyopathy
DVT
isn’t directly connected with thrombotic processes in coronary circulation
The most important risk factor of ATH
a) high seLDL
b) high seHDL
c) high seTG
d) high seCholesterol
high seLDL
chronic high cholesterol and changes to the LDL/HDL ratio are key factors in the pathomech of ATH since its the toxic metabolites of oxidation that leads to plaque. high TGs are less significant compared to LDL.
risk factors for CAD except for
a) positive family history
b) DM
c) smoking
d) high seHDL
e) metabolic syndrome X
high seHDL
HDL is protective against the dev of ATH
The ideal target value of seLDL in a DM patient after an MI
a) < 1.8 mmol/L
b) > 2.6 mmol/L
c) < 3.5 mmol/L
d) > 3.5 mmol/L
< 1.8 mmol/L
target value in very high risk pt is lower than primary prevention
A 65 pt with a history of smoking presents with sudden pain in his left leg. The limb feels cold and the toes are pale and peripheral pulse can’t be felt.
a) DVT
b) Buerger’s disease
c) embolism in the peripheral arteries
d) Raynauds disease
embolism in the peripheral arteries
symptoms developed quickly unlike in DVT which would have a pulse. Buerger’s is also slow.
Paramedics arrive to a 55yo pt with chest pain that started 3h ago. On the ECG there’s elevations in I, aVL, V5, and V6. What should they do?
a) transfer the pt to the regional ER
b) transfer the pt to the regional coronary care unit
c) transfer the pt to the regional cardio dept for a troponin test and if positive transfer to a PCI center
d) transfer the pt to the closest PCI center
transfer to the closest PCI center
they have a STEMI which is almost always bc of coronary occlusion and PCI is the best way to fix it so don’t delay at all
Upon physical exam of a 45yo man w/o symptoms of a soft systolic murmur and ejection click can be heard in 2L2. This has been known since he was a child so what was the diagnosis?
a) patent DA
b) coarctation of the aorta
c) ventricular septal defect
d) Ebstein’s anomaly
e) pulmo valve stenosis
pulmonary valve stenosis
organic heart disease since childhood without any symptoms is likely pulmo stenosis. patent DA causes continuous murmur, coarctation causes high BP in the upper limbs, VSD causes very loud systolic murmur,

a) it causes pulus parvus et tardus
b) it can cause syncope
c) it can cause angina like chest pain
d) Austin-Flint murmur can be heard upon auscultation
e) it causes concentric left ventricular hypertrophy
Austin-Flint murmur
AF murmur can be heard in aortic regurgitation, not stenosis
Correct statements about aortic insufficiency, except for
a) it causes pulsus celer et altus (Corrigan’s pulse)
b) it can be acute and chronic
c) usually doesn’t lead to LV dilation
d) can be congenital
e) it predisposes to infective endocarditis
it doesn’t usually lead to LV dilation
it does lead to LV dilation due to volume overload

d) antidromic AV reentry tachycardia (WPW)
e) Aflutter with BBB
Atrial fibrillation with BBB
Afib might have narrow and wide QRS complex but they’re always regularly irregular
