MTB 3 - Cardio Flashcards
Worst risk factor for CAD
DM
Most common risk factor for CAD
HTN
Risk Factors for CAD
DM, tobacco, HTN, hyperlipidemia, 1st degree family member with premature CAD, Men >45 & Women > 55
Correcting which risk factor shows greatest improvement with CAD?
smoking cessation
50% 1 year, 90% 2 years after smoking
Ischemic Pain
dull or sore
squeezing or pressure-like
Non-ischemic pain
Sharp or point-like
lasts for a few seconds
Changes with respiratoin (pleuritic), position, touch/tenderness
Chest Wall Tenderness
Costochondritis
Do PE
Radiation to back, unequal BP in arms
Aortic Dissection
chest x-ray-widened mediastinum
chest CT, MRI, or TEE confirms Dx
Pain worsens with lying flat, better when sitting up
Pericarditis
EKG with ST-elevation everywhere, PR depression
Epigastric discomfort, pain better when eating
Duodenal ulcer disease
Endoscopy
Bad taste, cough, hoarseness
GERD
Response to PPIs; Alumium hydroxide and Mg hydroxide, viscous lidocaine
Cough, sputum, hemoptysis
Pneumonia
CXR
Sudden-onset SOB, tachy, hypoxia
PE (can have fever)
Spiral CT*, V/Q scan
Sharp, pleuritic pain, tracheal deviation
Pneumothorax
CXR
Best initial test for chest pain
EKG
EKG not diagnostic and etiology of chest pain unclear-next step
stress test
Mortality lowering drugs with chronic angina
1) Aspirin-(clopidogrel used in apsirin intolerant pts or new stented pts)
2) Beta blockers-B1 spec. metoprolol
3) Nitroglycerin
Statin AE
Elevated transaminases (AST/ALT) do liver fxn tests Myositis
Niacin AE
Pruritis (+histamine)
elevation glucose and uric acid level
Fibric Acid derivatives (gemfibrozil) AE
increase risk myositis with statins
Cholestyramine AE
flatus, abd cramping
Ezetimibe AE
well tolerated, add to statins, not very useful
ACS confirmed on EKG, next step
Aspirin-shown to decrease mortality
clopidogrel is aspirin intolerant or if pt has stent already
ACS confirmed, aspirin given, next step
Angioplasty (90 min door time)>thrombolytics
Thrombolytics only used if angioplasty not available, in STEMIs, or new LBBB
NSTEMI-use heparin instead
contraindications to thrombolytics
1) hx major bleeding to brain/bowel
2) recent surgery-2 wks
3) severe HTN-180/110
4) nonhemorrhagic stroke in last 6 months
Indication for tPA (thrombolytics) in MI
only beneficial with STEMI
Indication for heparin in MI
best for NSTEMI (LMWH)
Indication for GP IIb/IIIa inhibitors in MI
best for NSTEMI and undergoing PCI and stenting
Post MI routine meds on d/c
1) Aspirin 2) Beta blockers (metoprolol) 3) Statins 4) ACEi
CHF Systolic vs Diastolic
Systolic- low EF, dilation of heart, or diastolic dysfxn.
can’t get blood out
Diastolic- inability of heart to relax and receive blood
EF is preserved, can be increased
Top causes of systolic CHF
HTN #1, MI, cardiomyopathy, valve disease-(95%)
-all can lead to dilated cardiomyopathy
Other causes of systolic CHF
alcohol, postviral idiopathic myocarditis, radiation, doxorubicin, Chagas (other infxns), Hemochromatosis (restrictive too), Thyroid dx, Peripartum cardiomyopathy, Thiamine deficiency
Sxs CHF
#1- SOB/dyspnea upon exertion orthopnea, peripheral edema, rales, JVD, paroxysmal nocturnal dyspnea, S3 gallop (fluid overload)
Dyspnea, sudden onset, clear lungs
PE
Dyspnea, sudden onset, wheezing, increased expiratory phase
asthma
Dyspnea, slower, fever, sputum, unilateral rales/rhonchi
Pneumonia
