(b)(4) clinical study.It was reported that death occurred.In (b)(6) 2013, the patient presented due to unstable angina, myocardial infarction (mi) and was referred for cardiac catheterization.Subsequently, the index procedure was performed.Target lesion # 1 was a de novo lesion located in the proximal left anterior descending (lad) artery with 90% stenosis and was 20 mm long with a reference vessel diameter of 3.00mm.Target lesion # 1 was treated with direct placement of a 3.50 x 24 mm promus element¿ plus stent with 0% residual stenosis.Three days post index procedure, the patient was discharged on aspirin and clopidogrel.In (b)(6) 2016, the patient presented to her local physician¿s office with complaints of progressive fluid volume overload and corresponding worsening shortness of breath consistent with an worsening of her chronic heart failure.Later, the patient was transferred to the local emergency department for further evaluation, where a brain natriuretic peptide (bnp) of greater than 5,000 and chest x-ray supported the presumed diagnosis of decompensated systolic heart failure and lab examination demonstrated acute renal failure with hyperkalemia secondary to decompensated heart failure.Subsequently, the patient was admitted for aggressive stabilizing therapy including aggressive iv diuresis, fluid volume restriction, iv steroids and antibiotics to treat possible pneumonia.Despite these measures; the patient had poor urine output and worsening creatinine clearance.In addition, the patient also had chronic obstructive pulmonary disease (copd) exacerbation/bronchitis and acute on chronic stage iii kidney failure secondary to decompensated heart failure, which were treated medically and 1 unit of prbcs was transfused for treating worsening anemia of chronic disease.One day post admission, the patient's overall condition worsened due to cardiovascular decompensation and associated compromise of renal perfusion.Discussions and preliminary arrangements were made to transfer the subject to rapid city regional hospital.In view of serious condition of the patient, discussion was made with the patient/ family members and the patient had a dnr/dni status but with daughter at bedside agreed to a brief period or resuscitation if necessary but not prolonged cpr or intubation.The patient subsequently experienced bradycardia in the 50¿s and then 30¿s which was treated with atropine and dobutamine infusion.Subsequently, the subject lost consciousness and pulses were no longer palpable.Code blue was called cardiopulmonary resuscitation (cpr) and lucas2 were initiated and external pacing was attempted with minimal success.Advanced cardiac life support (acls) protocols were utilized.Despite these efforts, the subject did not recover.After 45 minutes of cpr and discussions with immediate family members code blue was called off and cpr/ lucas2 was stopped.Life support systems and subsequent comfort care measures were also withdrawn.Upon examination, no spontaneous breathing or pulses were noted and the patient expired.Primary cause of death was "prolonged qt interval with bradycardia" and secondary cause of death was "end stage systolic congestive heart failure (chf) with acute decompensation¿.Contributing factors included acute renal failure (arf) on (chronic kidney disease (ckd)-iii with hyperkalemia, iron deficiency anemia, copd exacerbations, atrial fibrillation and uncontrolled on-insulin dependent diabetes mellitus (niddm).
