IHD Flashcards
(12 cards)
Stable angina
Exertional chest pain Relieve by tng or rest Secondry to artheriosclerosis No necrosis ST depression
Prinzmetal (vasospastic) angina
Secondary to spasm coronary
Transient ST elevation
* HTN and HLP are not risk factors
Trigger: alcol o cocain
Tx: no smoking, CCB, nitrates
Unstable angina
Thrombosis > incomplete occlusion
Unlike NSTEMI no cardiac marker elevation
With or wothout st depression and/or t inversion
At rest chest pain
Sudden cardiac death
CAD
cardiomyopathy (dilated and hypertrophic)
Hereditary ion channelopathy (QT syndrome, Brugada)
Arrhythmia like VF
prevention : ICD
STEMI
Transmural
NSTEMI
Subendocardial
MI complications 0-24 hrs
Coagulative necrosis Edema Hemorrhage Wavy fibers Reperfusion injury Free radical generation Lead to : - ventricular arrhythmia -HF -cardiogenic shick
MI complications 1-3 days
Acute inflamation around necrosis
Extensive coagulative necrosis
Lead to :
-post infarction fibrinous pericarditis
MI complication 3-14 days
Macrophage Granulation tissue at margins Lead to -free wall rupture and tamponade -papillary rupture and MR -interventricular septal rupture -LV pseudo aneurysm
MI complication 2w to several months
Dressler syndrome HF Arhythmia Ventricular aneurysm (risk of mural thrombus) Contracted scar
STEMI Tx
Reperfusion therapy (percutaneous intervention prefered over fibrinolysis) \+ NSTEMI tx
NSTEMI
For pain (morphin tng) Statin Betablocker Ace inhibitor Anticoagulation (heparin) Anti platelets (aspirin ADP receptor inhibitor (clopidogrel)
