Cardiology Facts 53

 

  • Atrial arrhythmia predict prognosis in massive pulmonary embolism with hemodynamic compromise 
  • Well compensated dilated cardiomyopathy - treatment ACE inhibitor and β-blockers 
  • Snoring, automobile accidents, overweight, HTN, right ventricular hypertrophy - obstructive sleep apnea 
  • Persistent left SVC is associated with coronary sinus ASD
  • ACE inhibitors reduce fatal and nonfatal events after MI in elderly patients 
  • In symptomatic patients with familial forms of dilated cardiomyopathy, histologic examination of heart demonstrates extensive areas of interstitial and perivascular fibrosis 
  • Rise in Cr after lisinopril ≤30% - continue current therapies
  • HTN, hypokalemia and mild hypernatremia - Conn syndrome(primary hyperaldosteronism) test morning renin and aldosterone concentrations
  • Ischemic stroke resolved with IV fibrinolytics, ECG, CT, CT angio head & neck, TEE with bubble study all normal - next 30 day Holter monitor for occult paroxysmal Afib 
  • ETT parameters of poor prognosis include <5 METs, failure to increase SBP ≥120 mmHg, or sustained decrease ≥10 mmHg, or below rest levels, during progressive exercise, ST-segment depressions ≥2mm, angina pectoris at low exercise level
