Cardiology Flashcards
When stable angina becomes unstable angina, then NSTEMI
pain is worsening with less work
more pain with same work
refractory to nitroglycerine
NSTEMI with troponins
CAD RF
same as vascular disease:
Modifiable: DM Smoking HTN Dyslipidemia
Non modifiable:
Age (M>45 F>55)
FH
Diamond classification risk of CAD with symptoms
Substernal
Worse with exercise
relieved by Nitro
3/3 - typical
2/3 - atypical
CAD associated SXS
Dyspnea
NV
Diaphoresis
DX of CAD
ECG w/ ST Elevation or new LBBB
- STEMI goes to Cath
- R/O NSTEMI with triponin
If no, do STRESS TEST
STRESS TEST
Goal
Positive if:
85% maximum HR, have them sustain it
+ if CP or EKG or ECHO is positive
Nuclear stress test with perfusion can show reversibility
Cardiac cath
tells you extent
R/O prinzmetals
Pateint presents with Angina - Acute Therapy
Aspirin
Nitrates (can alleviate pain BUT avoid if right-sided: 2,3 AVF)
MONA BASH
Morphine, Oxygen, Nitrates, Aspirin, BB, Aspirin , Statin Heparin
tPA / heparin acutely only if within 12 hours and no Cath available
Chronic therapy for CAD risk factors
Statin (high potency)
DM - A1C <7 or 80-120 sugars
HTN 140/90
The four groups that should be on a high-intensity statin
Any vascular disease ( Stroke, CAD, PVD, Carotid stenosis)
LDL > 190
do ASCVD calculation, takes into account RF
What are the high intensity statins and their doses
-Caution if: _____ or ______. If either of those, then start on _____
If there is SA, then _____
Atorvastatin 40, 80
Rosuvastatin 20, 40
Liver or renal disease, go to moderate intensity
SA, stop, then start at lower
Statins: Baseline tests
SA tests
how often lipids
A1C, CK and LFTs
SA - Hepatits: LFTs , muscle: CK
Lipids every year
A1C q3mo
Myositis sxs
Sorness, weakness, muscle pain
Fibrates
LDL down, HDL up, second line to statins
In a pateint with an arrythmia, what makes them unstable?
CP
SOB
AMS
SBP<90
If unstable, pace slow shock fast
What arrythmias are fast, narrow and what do you give them if pt is stable?
Afib
Aflut
SVT
Can give Adenosine (rythem controll)
usually for Afib/ flut give Dilt (CCB). Can give B block (both for rate controll)
What arrythmias are fast, wide and what do you give them if pt is stable?
VT/VF
Torsods
Amiodarone
What arrythmias are slow, and what do you give them if pt is stable?
Heart BLocks 1 2a 2b 3
1 and 2a (wenky) get atropine
otherwise pace
When to do CPR?
What to do in CPR?
In cardiac arrest: the heart has stopped (No BP / No pulse)
Shock? Drug, 2 min CPR, Drug, 2min CPR
Start with Epi. Shock only in Vtach, Vfib. If it is PEA / Asystoli, give nothing on first break.
What is and what are the causes of Dialated Cardiomyopathy
DX
How do you treat it
Big heart, causes systolic failure. Ischemia Valve dz idiopathic infectious metabolic alcoholic autoimmune
DX - CXR, US
Treat - HF medications
HOCM
Teens , Big ventrical obstructs outflow, sudden death in teens, tx with B blockers
Restrictive Cardiomyopathy
Causes
Sarcoid, Amyloid, hemachromatosis, cancer, fibrosis
TX - gentle diuresis, xplant
What are Systolic and diastolic heart failure, and what are the causes
Systolic cant push blood forward
-Dialated cardiomyopathy, ischemic tissue, leaky valves
Diastolic cannot fill
-hypertrophy, infiltration, pericardial/deposition dizeases as well
Pathogenisis of HTN induced HF
Heart gets big and beefy, eventually becomes floppy. Catecholamines initially help overcome the hypertension, but eventually leads to neural hormonal cardiac remodeling
