He has hypertension, hyperlipidemia, and type 2 diabetes mellitus. Current medications include lisinopril, simvastatin, and insulin. The patient appears tired but in no acute distress. His pulse is 70min, blood pressure is 14085 mm Hg, and respirations are 25min. He has crackles over both lower lung fields and 2 pitting edema of the lower extremities. An ECG shows T wave inversions in leads V1 to V4. Which of the following agents is most likely to improve the patients long-term survival?? A: Gemfibrozil, B: Metoprolol, C: Digoxin, D: Amlodipine, E: Dobutamine,  <response>: This is a question about choosing the most appropriate medication to improve long-term survival in a 70-year-old man with symptoms and signs of heart failure, including shortness of breath, coughing while sleeping, crackles on lung exam, edema, and ECG changes. Based on the description, he likely has systolic heart failure. His other medical conditions and medications provide context. The goal is to improve his long-term survival, so we need to consider medications that have been shown to reduce mortality in patients with systolic heart failure. The choices provided include medications for hyperlipidemia gemfibrozil, hypertensionangina metoprolol, amlodipine, arrhythmias digoxin, and acute heart failure dobutamine. Of these options, beta blockers like metoprolol have the strongest evidence for reducing mortality in chronic systolic heart failure.B: Metoprolol
