Pathophysiology Flashcards
CAD Etiology
Narrowing of the coronary arteries limits blood supply to the heart muscle causing angina (CP specifically due to heart muscle ischemia)
CAD Catch Prase
CP WITH PHYSICAL EXERTION
CAD Chief Complaint
CP or Chest pressure
- Worse with exertion
- Improved by rest or NTG
CAD Assoc. Med
ASA 324 mg PO, NTG 0.4 mg SL
CAD Dx by
Cardiac Catheterization (not diagnosed in ED)
CAD Scribe Alert
1) CAD greatest risk factor for MI
2) Stress test/Cardiac Catheterization to see severity
3) CAD if PMHx of Angina, MI, CABG, cardiac stents, or angioplasty
4) ASA 324mg PO ASAP unless given PTA or contraindicated due to bleeding or allergy
MI Etiology
Acute blockage of the coronary arteries results in ischemia and infarct of the heart muscle
MI Catch Phrase
Chest pressure WITH DIAPHORESIS, N/V, SOB
MI Risk Factor
CAD, HTN, HLD, DM, Smoker, FHx of CAD
MI Chief Complaint
CP or Chest Pressure
MI Dx By
EKG (STEMI) or elevated Troponin (non-STEMI) reg =.05
MI Assoc. Med
ASA, NTG, B-Blocker, Thrombolytic (heparin)
CHF Etiology
The heart becomes enlarged, inefficient, and congested with excess fluid.
CHF Catch Phrase
SOB with PEDAL EDEMA and ORTHOPNEA
CHF Chief Complaint
SOB - ORTHOPNEA (worse lying flat)
- PND (paroxysmal nocturnal dyspnea)
- DOE (dyspnea on exertion)
CHF PE
Rales in lungs
JUV in neck
Pitting pedal edema
CHF Assoc. Med
Diuretics (Lasix, Furosemide) to inc. urination
CHF Dx By
CXR or ELEVATED BNP (B-type Natriuretic peptite)
CHF Scribe Alert
Fluid traffic jam in the heart
AFIB Etiology
Electrical abnormalities in the ‘wiring’ of the heart causes the top of the atria to quiver abnormally
AFIB Chief Complaint
Palpitations (fast, pounding, irregular)
AFIB Risk Factors
Paroxysmal A fib (ocassionally)
Chronic A fib (more frequently)
AFIB PE
IRREGULARLY IRREGULAR RHYTHM, Tachycardia
AFIB Dx By
EKG (ECG)
