C-CHF +1 H-Hypertension +1 A- Age>65 +1, >75 +2 D- Diabetes +1 S- Stroke history (DVT/TIA/CVA/Thromboembolism) +2 V- Vascular history +1 Femal e -+1 0- no need for treatment 1- consider anti platelet or anticoagulation >2- anticoagulation necessary What is the INR range for patients taking warfarin for atrial fibrillation? - answer✔✔2-3 ! What presents with intermittent claudication (pain in a muscle group induced by exercise and relieved with rest), decreased distal pedal pulses, cool, shiny extremity with decreased hair? Dx and Tx? - answer✔✔Peripheral Arterial Disease! Dx: ABI- Ankle -Brachial Index (measure BP in arm vs leg) <.9% indicates stenosis , <.4% indicates ischemia --> Simple, quick, noninvasive most useful screening tool Arteriography --> Gold standard (visualizes atherosclerosis inducing ischemia) US--> noninvasive, used for visualizing stenosis Tx: Lifestyle modifications, inc reased exercise & tobacco cessation Statins, ASA, Antiplatelets (Clopidogrel, Cilostazol) Peripheral arterial disease most commonly affects which vessels? - answer✔✔Superficial femoral artery (calf pain) Aortoiliac system (thigh/buttock pain). Which of the following features can differentiate myocardial infarction from pericarditis? - answer✔✔Reciprocal changes in EKG! Meaning... ST depression in the leads opposing ST elevation! --> ONLY occurs in MI, will never occur in pericarditis Ex: Anteri or vs Inferior are reciprocal leads, so if anterior has elevations, inferior would have depressions What is Dressler's syndrome? - answer✔✔Post-myocardial infarction pericarditis. What presents with pleuritic chest pain radiating to back, worse when laying back, improved when leaning forward, with tachycardia and pericardial friction rub? Dx and Tx? - answer✔✔Pericarditis!

Which cardiac biomarker is useful for assessing a re -infarction during the hospital stay? - answer✔✔CK-MB , because troponin will last for up to 14 days and therefore would not be good indicator of whether another heart attack occurred ! What is the earliest ECG sign of MI? - answer✔✔hyperacute T waves What cardiac biomarker has the highest sensitivity and speci ficity? - answer✔✔Troponin I! What is the #1 cause of death in the US? - answer✔✔Ischemic Heart Disease! What is the most common symptom of cardiac ischemia in patients older than 85 years? - answer✔✔Dyspnea! Which of the following is the most predictive r isk factor for cardiac ischemia? - answer✔✔PMH of CAD! Tobacco smoking, family history of CAD, and DM are also risk factors, but not as strong as having personal history of CAD What is the most common cause of cardiac related syncope? - answer✔✔Cardiac Dy srhythmias What is the scaling used for assessing syncope? - answer✔✔San Francisco Syncope Scale: CHESS C-CHF H-Hematocrit <30%
