Tysоn is а 50 yо blаck mаle with a past medical histоry significant for hypertension and a heart attack (resulting in reduced LVEF) one year ago. He is currently taking lisinopril (Zestril*) and a higher dose of amlodipine (Norvasc*). He says he is having ankle edema over the past couple months since amlodipine (Norvasc*) was started. His kidney function is normal, and he has no other signs/symptoms of fluid accumulation (e.g. pulmonary congestion, weight gain). His BP is 138/70, and HR 72. His laboratory values are normal. Considering not only hypertension, but his past medical history ( prior MI / stable HFrEF) and most recent complaint (ankle edema), which of the following recommendations is most appropriate for Tyson to correct the edema and optimize heart failure therapy?
