| Primary prevention ASA | No bleeding risk ( HASbled), life expectancy > 10 yr, 50-60: ASCVD risk > 10%, 60-70: Individual decision, > 50 with DM: ASCVD > 10% + one risk factor ( HTN, FHx, smoking) |
| Stable CAD treatment | ASA 81 mg, Statin mod/high dose, ACE, Antianginal( 1. BB,2. CCB, 3. Nitrate, 4. Ranolazine, life style factors. |
| Nuclear Stress test: Indications | Resting ST abnormality, LBBB, WPW, LVH, Paced Rhythm, Dig, Obese or COPD and can't exercise. |
| Nuclear stress test positive | ST depression > 2mm or > 1 mm in > 5 leads, VT, Low BP, Angina, < 4 mets, 1 large defect, > 2 reversible defects, increase lung uptake : Any of these will go on to angiography |
| Risk assessment screening test | CRP > 2, CA Calcification > 300 , ABI < 0.9 If Elevated ASCVD > 7.5 councel re: BP , Chold, Wt, lifestyle. Coronary CTA: anatomical test for plaque burden. Look at graft post CABG and help risk stratify, Calcium scan: Help determine if asymptomatic intermediate risk needs statin to stabilize plaque. Do not repeat. |
| Lipid treatment guideline | 1. ASCVD < 75 y.o - high intensity statin, > 75 yo - low intensity, 2. Severe LDL > 190 in 20-75 - max tolerated statin, 3. DM > 40 - mod intensity, DM > 40 with 10 yr risk > 20% - high intensity statin, 4. Adults > 40-75 with ASCVD risk > 7.5% - moderate intensity statin. |
| What are moderate intensity statins? | Atorvastatin 10 mg/d, Fluvastatin 40 mg bid, Simvastatin 20 mg/d Harmful if exceed > 40 mg/d. |
| What is high intensity statin? | Atorvastatin 40-80 mg/d, Rosuvastatin 20 mg/d. |
| How do you treat statin myalgia | Look for interacting drugs, Check CPK, . 10 stop med, lower statin dose or give it 1-2x/wk, Check ALT yearly. |
| What are secondary causes of elevate lipids? | DM, ETOH, Thyroid, obesity and drugs ( HCTZ) |
| What type of murmur is MR and what causes it? | Systolic murmur, caused by MVP and RF |
| How do you manage MR? | Look for sx: dyspnea, fatigue. Monitor yearly echo, Referr for surgery if abnormal LV size or function, pulmonary HTN, or new onset A fib. |
| What type of murmur is MS | Diastolic with open snap, caused mostly by RF |
| How do you manage MS? | If symptomatic with diuretics and rate control. Prone to A fib and pulmonary HTN,. Referr to surgery when valve are is < 1.3 |
| Who need antibiotic prophylaxis for Infective Endocarditis? | 1. prosthetic valve, 2. Previous IE, 3. Heart transplant, 4. Congenital HD |
| Which heart block do you pace? | Symptomatic ones. Mobitz type 2 and 3rd degree. If unstable give atropine. Look for reversible causes. |
| How do you treat hemodynamically unstable bradycardia? | HR < 50 with confusion, angina, dyspnea : Give Atropine 0.5mg IV Q 3-5 min If not better temporary transcutaneous pacer. Sadate if conscious. Give Dopamine for low BP and Dobutamine for CHF. |
| What are some of the reversible causes for bradycardia? | Medication: BB, Clonidine, Acetylcholine, sedatives, opioids, cimetidine, Dig, CCB, Amiodarone, lithium, Acute MI, OSA, Increase valsalva, Increased ICP, infection and hypothyroid. |
