Cardiology Facts 63

 

  • Aortic homograft has lowest incidence of endocarditis 
  • >3 coronary artery disease risk factors, aspirin use in past 7 days, angina in past 24 hours, increased troponin, nonspecific ST-T wave abnormalities, TIMI risk of 2 or greater benefit from early invasive management strategy coronary angiography within 48 hours  
  • AFib+PCI, oral anticoagulation therapy plus clopidogrel, without aspirin (“double therapy”), significantly reduces bleeding rates compared with “triple therapy” (anticoagulation plus aspirin and clopidogrel)  
  • If <70% non-left main stenosis, FFR <0.80 - guideline directed medical therapy is first recommended approach 
  • Fever, myalgias, heart failure, severe LV dysfunction - most common pathogen Parvovirus  
  • Facial and periungual telangiectasias, skin over fingers appears thickened and tight, enlarged PA, enlarged RV, echo flattening of IVS - systemic sclerosis 
  • Restrictive lung disease, syncope, first-degree AV block, RBBB - Cardiac sarcoidosis 
  • VSD+IE, post treatment repeat blood cultures are negative, TEE is negative for vegetations - closure of VSD indicated  
  • Age is most important clinical predictor of 30-day mortality after acute STEMI
  • Aortic valve area 1 or less, velocity less than 4, gradient less than 40, LVEF <50% - severe low flow, low gradient AS, next dobutamine stress echo
