Unstable angina (UA) versus and NSTEMI differ primarily in whether ischemia is severe enough to cause sufficient myocardial damage to release markers of myocardial injury.
Unstable angina = symptoms of ACS but NO elevation in troponin or CK-MB, with or without ECG changes of ischemia (eg, ST segment depression or transient elevation or new T wave inversion). |

Definition de FA: paroxystique: resolves within 7 days, with or without ttt permanent/persistant: AF that fails to self-terminate within seven days |
TT FA (simplfié): 1er choix: BB et CCB 2eme choix: amiodarone 3eme choix: digoxin |
|
|
FA ttt options: must consider- 1- rate versus rythym control 2- anticoagulation? |
failure of RATE controle: 1- persistance des symptomes (palpitations etc) OU 2- FC inacceptable (trop rapide) |

Pulseless electrical activity
refers to a clinical diagnosis of cardiac arrest in which a heart rhythm is observed on the electrocardiogram that should be producing a pulse, but is not. Under normal circumstances, electrical activation of muscle cells precedes mechanical contraction of the heart (known as electromechanical coupling). In PEA, there is electrical activity, but the heart either does not contract or there are other reasons why this results in an insufficient cardiac output to generate a pulse and supply blood to the organs.[1] |

Cardiaque arrest
VF, VT (ie shockable rhythm)- CPR and shock + EPINEPHRINE, amiodarone 2er choix surtout si arythmie.
PEA, asystole- CPR and EPINEPHRINE, 2er choix vasopressor |
Tachycardie (sinusal i.e. narrow complex) 1. valsalva manouevres 2. ADENOSINE (CARDIOVERSION) 3. BB OU CCB (verapamil)

Phlegmasia cerulea dolens: -uncommon severe form of DVT which results from extensive thrombotic occlusion of major & collateral veins of MI/MS. Sx: sudden severe pain, swelling, cyanosis + edema. -High risk of massive EP, even w/ anticoagulation. -Foot gangrene may also occur. -Disparition des pouls distaux - 50% thrombosent les capillaires → nécroses veineuses irréversibles en 6h -Underlying malignancy is found in 50% of cases. -Occurs in those afflicted by a life-threatening illness |
