Flashcards in midterm path Deck (15):
1

risk of rupture with partial or complete lumen occlusion by aggregated platelets/thrombus:

unstable plaque --> acute coronary syndrome

2

time of complete ischemia to cardiac death?

30 min

3

isolated/pure right-sided hypertensive heart disease:

cor pulmonale

***due to chronically increased pulmonary artery pressure

4

most common etiology of valvular disease in DEVELOPED countries:

calcified aortic stenosis

mitral valve prolapse

5

intrinsic myocardial disease NOT associated with ischemic, valvular, hypertensive, or congenital structural heart disease:

cardiomyopathy

-dilated, hypertrophic, or restrictive

ex: myocarditis, drug induced (etoh, chemo), hemochromatosis, amyloidosis

6

cardiac neoplasia in children with tuberous sclerosis

Rhabdomyoma

7

most common site of metastases to heart?

pericardium (vs mycardium...rare)

8

Life threatening (must not miss) ddx for CP in ER (6 of them):

MI
PE
aortic dissection/rupture
tension PTX
PNA
esophageal rupture

9

Life threatening ddx for dyspnea/respiratory distress in ER: (9 of them)

1. foreign body obstruction
2. anaphylaxis
3. bronchospasm (status asthmaticus)
4. acute pulmonary edema (CHF vs ARDS)
5. PE
6. tension PTX/ large pleural effusion
7. PNA
8. shock-massive hemorrhage or acute hemolysis
9. toxic metabolic effect on CNS resp control center

10

hypercarbia = pCO2 > ?

45 mmHg

alveolar hypoventilation usually result of obstructive pulm disease

11

One month mortality for acute MI:

30%

12

Commonest source of clinically significant valvular heart disease?

aortic, mitral (left sided)

13

Almost all cases of mitral stenosis from?

rheumatic fever

14

systolic click murmur syndrome = ?

mitral valve prolapse

mild cases are usually young women

15

Common pathogen in infectious endocarditis of prosthetic valves:

coagulase negative staph

epidermitis???
