if initial EKG and/or enzymes do NOT establish diagnosis of CAD, next step
stress test

treatment for septal rupture

260
- causes acute chest pain
- can occur with exertion or at rest
- ST segment elevation, depression, or normal EKG
- NOT based on enzyme levels, angiography, or stress test results

262
AR murmur description and location it's best heard
- diastolic decrescendo murmur
| - LEFT sternal border
263
when do you balloon dilate AS?
ONLY when patient can't tolerate surgery
264
how long do mechanical valves last?
15-20 years
need to be on warfarin with INR of 2-3
265
what does EKG show in RCMP?
low voltage
266
best INITIAL test for AS
TTE
267
diagnostic tests for cardiogenic shock
- echo
| - Swan-Ganz (right heart) catheter
268
best INITIAL test for MR
TTE
269
situations where patient won't be able to do an exercise stress test
1. COPD
2. amputation
3. deconditioning
4. weakness/previous stroke
5. LE ulcer
6. dementia
7. obesity
270
exertional SOB: Turner's syndrome, coarctation of aorta
BICUSPID aortic valve
271
treatment for MAT
1. oxygen FIRST
| 2. THEN diltiazem
272
contraindicated with sildenafil (PDI's)
nitrates
273
cause of chest pain that is tender to palpation
costochondritis
274
causes of POSITIONAL chest pain
pericarditis
275
MOST DANGEROUS thing to give a patient with pericardial tamponade
diuretics
276
when should you order a dipyridamole or adenosine thallium stress test, or dobutamine echocardiogram?
patient can't exercise to target HR of > 85% of maximum
277
best INITIAL treatment for PAD
1. aspirin
2. BP control with ACEI
3. exercise as tolerated
4. cilostazol
5. statin with LDL goal
278
mechanism of crescendo-decrescendo murmur of AS
- isovolumetric contraction = no blood moving = no murmur
| - mid-systole = peak flow = peak noise
279
clinical diagnosis of acute pulmonary edema
1. SOB
2. rales
3. S3 (splash)
4. orthopnea
280
- SOB
- hypOtension
- jugular venous distention
- lungs CTA
- PULSUS PARADOXUS (BP decrease > 10mmHg on INhalation)
- ELECTRICAL ALTERNANS (alternating QRS complex heights)
pericardial tamponade
281
pulmonic valve murmurs are best heard where?
2nd LEFT intercostal space
282
AS murmur description and location it's best heard
- crescendo-decrescendo
| - 2nd RIGHT intercostal space radiating to CAROTIDS
283
S4 gallop indicates
left ventricular HYPERTROPHY
284
- holosystolic murmur at LLSB
- SOB
- parasternal heave
VSD
285
best INITIAL therapy for AR
- ACEI/ARB, or nifedipine
| - and loop diuretic
286
MAT EKG finding
POLYMORPHIC P waves
287
MORE ACCURATE test for MS
TEE
288
best INITIAL test for DILATED cardiomyopathy
echo
| check EF and wall motion abnormality
289
best INITIAL test for dissection of thoracic aorta
CXR showing WIDENED MEDIASTINUM
290
other tests to order once atrial fibrillation is diagnosed
1. echo: looking for clots, valve function, LA size
2. TFT: TSH, T4
3. electrolytes: K+, Mag2+, Ca2+
4. troponin/CK
291
which medications decrease afterload?
1. amyl nitrate
| 2. ACEIs
292
MC of post-MI erectile dysfunction
anxiety
293
mechanism of pulsus paradoxus
inhale = big RV = smaller LV = BP drop > 10mmHg
294
further evaluation of syncope if diagnosis is still unclear after INITIAL tests
- Holter monitor as outpatient
- telemetry monitor as inpatient
- repeat cardiac enzymes
- urine/blood toxicology
295
finding on echo in pericardial tamponade
diastolic collapse of RA and RV
296
MOST ACCURATE test for AS
left heart catheterization
297
what LOWER MORTALITY in STEMI and are TIME DEPENDENT?
thrombolytics and PCI
