Cardiology Facts 68

 

  • Noncardiac surgery should be postponed for at least 6 weeks following implantation of BMS and 6 to 12 months following DES implantation
  • LVEF ≤35%, sinus rhythm, LBBB QRS duration of ≥150 msec, NYHA class II, III, IV on GDMT - CRT
  • Renovascular hypertension due to atherosclerosis progression more likely to complete renal artery occlusion as opposed to fibromuscular hyperplasia
  • With aortic atheroma alternative sites for cross-clamping or cannulation reduce stroke risk
  • Motor vehicle collision, FAST USG no pericardial effusion, CT rib fracture & pulmonary contusion, over time hypotension, tachycardia, ST depression - next TTE
  • Cilostazol’s benefits in peripheral arterial disease arise via inhibiting phosphodiesterase 3, increased cAMP
  • Framingham Risk Score does not take family history into account, may not accurately calculate risk in certain ethnic groups because original Framingham population was almost entirely of European origin does not include emerging risk factors such as CRP, lipoprotein(a), and apoB
  • BP >180/120, extremity edema, low oxygen saturation - transfer to emergency department for further evaluation and treatment
  • In ACS, LDL-C 70 mg/dL or more despite statin at highest tolerated dose and ezetimibe, start PCSK9i evolocumab 140 mg subcutaneously every 2 weeks
  • Chest pain, single S2, late peaking murmur systolic murmur loudest at second intercostal space, radiating to neck, diminished carotid upstroke (severe AS) - cardiac catheterization can measure transvalvular gradients and assess coronary anatomy
