Given Mr. Jackson’s previous MI and coronary artery stent placement from five years ago, how would you initially approach his care? • What is the potential significance of the patient’s high blood pressure and elevated heart rate given his current signs and symptoms? • How might the presence of atrial fibrillation, lower extremity edema, crackles auscultated in lung lobes, and reduced ejection fraction on the echocardiogram be connected? • What implications does the diagnosis of atrial fibrillation have for the patient’s overall treatment plan, such as medication changes or lifestyle recommendations? • Why is Mr. Jackson’s troponin elevated but his CK-MB is normal?
