Cardiology Facts 58


  • VSR - Urgent surgical repair 
  • NSTEMI, ongoing chest discomfort, tadalafil intake less than 48 hr, no C/I to beta blocker - treatment beta blocker eg oral metoprolol 25 mg 
  • Asymptomatic infrarenal AAA should be repaired at size 5.5 cm or greater 
  • For diagnosis of metabolic syndrome, cutoffs for HDL-C are <40 mg/dL in men but <50 mg/dL in women 
  • Metolazone has side effect of hypercalcemia 
  • NSTEMI, bibasilar crackles, TTE severe MR - immediate invasive (2hr) strategy, test coronary angiography 
  • Low-dose rivaroxaban (2.5 mg BID) with aspirin reduces incidence of major cardiac and adverse limb events in patients with stable PAD compared with aspirin alone 
  • Palpitations and lightheadedness while playing (CPVT) + family history - mutations is most likely in ryanodine receptor 
  • Chronically rapid ventricular rate in AF results in impaired LV systolic function 
  • Low BP, low cardiac output, high PCWP, high pulmonary artery pressure (cardiogenic shock), maximal pressor support and IABP, ECG sinus tachycardia - next LVAD
