A 56-year-old man comes to the emergency department complaining of substernal chest pain that radiates to the left shoulder. Electrocardiogram (EKG) demonstrates ST-elevations in leads II, III, and aVF. The patient subsequently underwent catheterization with drug-eluting stent placement with stabilization of his condition. On post-operative day 3, the patient experiences stabbing chest pain that is worse with inspiration, diaphoresis, and general distress. His temperature is 98.7°F (37.1°C), blood pressure is 145/97mmHg, pulse is 110/min, and respirations are 23/min. EKG demonstrates diffuse ST-elevations. What is the best treatment for this patient?
ALisinopril
BSurgery
CNeedle thoracotomy
DAtorvastatin
EAspirin
A 53-year-old man with a past medical history significant for hyperlipidemia, hypertension, and hyperhomocysteinemia presents to the emergency department complaining of 10/10 crushing, left-sided chest pain radiating down his left arm and up his neck into the left side of his jaw. His ECG shows ST-segment elevation in leads V2-V4. He is taken to the cardiac catheterization laboratory for successful balloon angioplasty and stenting of a complete blockage in his left anterior descending coronary artery. Echocardiogram the following day shows decreased left ventricular function and regional wall motion abnormalities. A follow-up echocardiogram 14 days later shows a normal ejection fraction and no regional wall motion abnormalities. This post-infarct course illustrates which of the following concepts?
ACoronary collateral circulation
BVentricular remodeling
CMyocardial hibernation
DMyocardial stunning
EReperfusion injury
A 79-year-old man is brought to the emergency department after he noted the abrupt onset of weakness accompanied by decreased sensation on his left side. His symptoms developed rapidly, peaked within 1 minute, and began to spontaneously resolve 10 minutes later. Upon arrival in the emergency room 40 minutes after the initial onset of symptoms, they had largely resolved. The patient has essential hypertension, type 2 diabetes mellitus, chronic obstructive pulmonary disease, and a 50 pack-year smoking history. He also had an ST-elevation myocardial infarction 3 years ago. His brain CT scan without contrast is reported as normal. Carotid duplex ultrasonography reveals 90% stenosis of the right internal carotid. His transthoracic echocardiogram does not reveal any intracardiac abnormalities. Which of the following interventions is most appropriate for this patient's condition?
ACarotid stenting
BWarfarin
CLow molecular weight heparin
DHypercoagulability studies
EAspirin and clopidogrel
