Review: Cardio, Resp, HEENT Flashcards
Risk factors for angina pectoris
- DM
- hyperlipidemia
- smoking
- HTN
- males
- age over 65
- hx of CAD
- obese
How do you dx angina pectoris/CAD
- ECG: ST depression w/ exertion, T wave inversion, poor R wave progression +/- normal
- Stress test
- Coronary angiography (gold standard)
When are radionuclid MPI stress tests used
pts w/ baseline EKG abnormalities, pts unable to exercise can do pharmoacologic
CI: asthmatics
Pharmacologic mangement of stable (chronic) angina
- Nitrates
- BB
- CCB
- ASA
Describe the cardiac markers used to dx AMI
CK/CK-MB: appears 4-6 hrs, peaks 12-24, returns to baseline in 3-4 days
troponin I and T: appears 4-8 hrs, peaks 12-24 hrs, returns to baseline 7-10 days ***most sensitive and specific
Med management of STEMI vs NSTEMI
STEMI: BB, NTG, ASA, heparin, ACEI, reperfusion tx**
NSTEMI: BB, NTG, ASA, heparin
management of cocaine induced MI
ASA, NTG, heparin, Anxiolytics (Benzos_
**AVOID BB due to risk of vasospasm (unopposed A1 constriction)
What do you do when you detect sx associated with ischemia or infarct?
- perform brief Hx and PE
* *ASK ABOUT phosphodiesterase inhibitors in last 48 hrs - obtain cardiac markers
- O2
- ASA (160-325mg)
- NTG (0.4mg sublingual or spray)
- Morphine IV
- EKG w/in 10 min
w/ ___ MI use IV nitrates and morphine w/ caution bc if may cause unsafe drop in BP
RV (inferior wall) MI
Tx of Prinzmetal angina
CCB, nitrates prn
*may give ASA and heparin until atherosclerotic disease is ruled out
When/How do you use the TIMI score?
assess risk of death and ischemic event sin pts w/ U A or NSTEMI (1 point for each)
- age 65 or older
- 3 or more CAD RF (Fhx, HTN, high Chol, smoker, DM)
- Known CAD (stenosis 50% or over)
- ASA use in past 7 days
- recent severe angina in past 24 hrs
- elevated cardiac markers
- ST elevation 0.5mm
scores of 3 or more are high risk
Tx for heart failure
at Least ACEI and diuretic
ACEI/ARB + diuretic + BB +/- spironlactone +/- digoxin unless Afib is first line tx
P’s of pericarditis
persistent, pleuritic, postural pain, and pericardial friction rub
*relieved when witting/leaning forward
Most common cause of percarditis
- viral (entero, coxsackie and echovirus)
- idiopathic (likely undx viral)
- Dressler’s syndrom (2-5 days s/p MI)
Tx of acute pericarditis
- NSAIDs or ASA for 7-14 days
- Colchicine 2nd line management - +/- corticosteroids if sx over 48 hrs and refraction
EKG of pericardial effusion
- low voltage QRS
2. electric alternans (short then tall QRS complexes)
What is becks triad
for pericardial tamponade
- distant (muffled) heart sounds
- increased JVD
- hypotension
*PT also has pulsus paradoxus
tx of pericardial tamponade and effusion
pericardiocentesis
Causes of aortic stenosis
- Degeneration if over 70**
- Congenital if less than 70y/o
- Rheumatic disease
Causes of mitral stenosis
- Rheumatic heart disease(MOST COMMON by far)
* seen w/ AFib and R-sided HF
Causes of aortic regurgitation
- Rheumatic dz, HTN
- endcarditis, marfan
- Syphilis
- Ankylosing spondylitis
*seen w L-sided HF
Causes of mitral regurgitation
- MVP (MOST COMMON)
- RHD, endocarditis
- Ischemia (ruptured papillary muscle/chordae tendinae s/p MI)
Causes of MVP
- most common in young women
2. Connective tissue dz (Marfan, Ehlers Danlos)
Causes of hypovolemic shock
- hemorrhage
2. fluid loss (vomiting, diarrhea, pancreatitis, severe burns)
Causes of cardiogenic shock
- MI
- myocarditis
- valve dz
- cardiomyopathy
- arrhythmias
Causes of obstructive shock
- pericardial tamponade
- massive PE
- tension PTX
- aortic dissection
Causes of distributive shock
- septic
- neurogenic
- anaphylaxis
- hypoadrenal
**CAUSES DECREASED SVR Unlike other shock categories
