Cardiology Facts 43

 

  • β-Blockers should be started in stable CHF patients 
  • Low JVP, dry mucous membranes, high Cr - isotonic saline infusion prior to coronary angiography minimises risk of contrast-induced nephropathy 
  • Corticosteroids lower HDL cholesterol
  • AVR, acute DVT, begin weight based unfractionated heparin infusion because in postoperative state rapid reversal of anticoagulation may be required 
  • Acute ischemic stroke, sinus rhythm - anticoagulation is not indicated for acute ischemic stroke of unclear etiology (Class III) 
  • UFH and bivalirudin degree of anticoagulation can be monitored using APTT 
  • Acute decompensated HF - hospitalise for IV furosemide therapy and hemodynamic monitoring 
  • Inferior wall MI, systolic murmur apex increases in grade over time - cause infarcted posterior papillary muscle
  • Primary PCI, hypotension, norepinephrine is most reasonable initial vasopressor 
  • Constrictive pericarditis is preload dependent condition. Diastolic equalisation of pressures, waveforms are not seen if lack of preload due to overdiuresis
