Cardio Flashcards
First line tx for CAD
decreases mortality
reduces myocardial O2 requirements during stress/exercise
Beta blockers
Increases vasodilation
prevents ischemia induced by coronary vasospasm
*decreases contractility
*decreases HR
*decreases afterload

*RF for CAD
horizontal or downsloping ST depression
*but, 25% will be normal
=ECG for..?
Angina
Which drug class will prolong life in CAD
Beta blockers
“post MI syndrome”
pericarditis
fever
leukocytosis
pericardial or pleural effusion
Dressler Syndrome
*usually 1-2 weeks post MI
ST elevation >1mm in 2 contiguous leads
Peaked T waves –> ST elevation –> Q waves –> T wave inversion
STEMI ECG changes
ST elevation in:
II, III, aVF
*where is the MI?
Inferior
ST elevation in:
V1, V2
*where is the MI?
Posterior or anteroseptal
ST elevation in:
v1, v2, v3
*where is the MI?
Anterior
ST elevation in
v4, v5, v6
MI?
Anterolateral
DOC for cocaine induced MIs or Prinzmetals?
CCBs
DO NOT USE BETA BLOCKERS
Timeline for…
- PCI?
- Thrombolytics?
PCI= 90 mins
Thrombolytics= 3 hours
Decreased EF
S3 gallop
*MC type of HF
Systolic HF
Normal EF
S4 gallop
Diastolic HF
Dyspnea, orthopnea, PND
Pulmonary congestion, rales, rhonci
Cheyne stokes
what side HF?
Left sided
Deeper, faster breathing with gradual decrease and periods of apnea
Cheyne Stokes
Peripheral edema
JVD
GI/hepatic congestion (hepatojugular reflex)
what side HF?
Right sided HF
DOC for CHF?
ACE
Kerley B lines
Butterfly pattern
Cardiomegaly
Pleural effusion
CHF CXR
ACE
ARB
Beta blockers
Hydralazine, nitrates
….are all ______ that decrease _____
vasodilators that decrease afterload
Diuretics work to decrease…
preload
Are CCBs used in SYSTOLIC or DIASTOLIC HF?
Diastolic only
At what ejection fraction can you start to consider an ICD?
<35%
MC cause= viral (coxsackie, echovirus)
CP, sharp and worse w inspiration
Worse with lying flat
Improved when leaning foreward
diffuse ST elevations in V1-V6
Pericarditis
- distant heart sounds
- increased JVP
- systemic hypotension
Beck’s triad
*seen in cardiac tamponade
>10 mmHg in SBP with inspiration
Pulsus paradoxus
seen in tamponade
2 things youll see low voltage QRS complexes
- cardiac tamponade
- pericardial effusion
MC cardiomyopathy
*50% idiopathic
*can be viral (coxsackie, echo, parvovirus)
*ETOH, cocaine
Dilated cardiomyopathy
How does dilated cardiomyopathy present?
Like systolic HF
*S3 gallop
(tx like HF…ACE, diuretics, beta blockers)
Apical left ventricular ballooning
*follows events that cause catecholamine surge
- -> ST elevations
- -> positive enzymes
- -> normal arteries on cath
Takotsubo cardiomyopathy
harsh systolic crescendo-decrescendo murmur best heard at LUSB
HCM murmur
what does the HCM murmur do with:
squatting and lying down
DECREASES
(bc venous return is increased)
what does HCM murmur do with:
standing, valsalva
INCREASES
(decreases venous return)
Most uncommon form of cardiomyopathy
*caused by amyloidosis, sarcoidosis, etc.
Restrictive cardiomyopathy
Valve most affected with Rheumatic fever?
Mitral valve
- migratory polyarthritis
- active carditis
- sydenhams chorea
- subcutaenous nodules
- erythema marginatum
major criteria for rheumatic fever
(minor= fever, arthralgias, ESR/CRP/WBC, prolonged PR)
Rheumatic fever tx?
Penicillin G
Seen following: TB, radiation therapy, cardiac surgery
right sided HF
+ kussmal’s
septal bounce
decreased mitral inflow velocities w inspiration
constrictive pericarditis
systolic ejection murmur in 2nd and 3rd ICS parasternally
*can lead to paradoxic emboli (lead to stroke)
patent foramen ovale
true or false
Right coronary artery supplies inferior heart
blockage would be shown in II, III, aVF
true
the LAD supplies which portion of the heart
anterior
(V2, V3, V4)
which lab is best to examine recurrent chest pain:
trops, CK-MB or CK
CK-MB
true or false
ostium secundum is the MC cause of ASD
true
often seen in premies
continuous machine like murmur
PDA
