AB A  55-year-old  woman  presented  to  your  clinic  for  a  follow-up.  She  was  diagnosed  with  nonischemic  cardiomyopathy  diagnosed9  months  ago  after  she  presented  to  the  emergency  department  (ED)  with  New  York  Heart  Association  (NYHA)  class  IV  heart  failure  (HF)  symptoms.  Coronary  angiography  then  revealed  no  obstructive  coronary  artery  disease  (CAD).  Echocardiogram  at  the  time  of  her  initial  evaluation  revealed  moderately  dilated  left  ventricle,  and  global  hypokinesis  with  an  ejection  fraction  of  20%,  with  no  gross  valvular  abnormalities.  Cardiac  magnetic  resonance  imaging  (MRI)  showed  midwall  fibrosis  consistent  with  nonischemic  cardiomyopathy.  During  her  clinic  visit,  she  reported  symptoms  of  effort  intolerance  and  exertional  dyspnea  with  mild  exertion.  She  denied  resting  or  exertional  chest  pain.  An  echocardiogram  at  the  time  of  her  visit  showed  left  ventricular  ejection  fraction  (LVEF)  of  25%.  Her  current  medications  include  carvedilol  25  mg  twice  daily,  lisinopril  10  mg  twice  daily,  aldactone  25  mg  by  mouth  once  a  day,  Lipitor  80  mg  by  mouth  once  daily,  Aspirin  (ASA)  81  mg  by  mouth  once  daily,  and  Plavix  75  mg  by  mouth  once  daily.  Electrocardiogram  showed  normal  sinus  rhythm,  left  bundle  branch  block  with  QRS  duration  of  155  ms.  Blood  Pressure  is  90/60  mm  Hg  and  heart  rate  is  70  beats  per  minute.  Her  cardiovascular  examination  was  unremarkable.
