ML is a 51 year-old Hispanic female. You have been following her for almost 2 years now and have been working very hard with her to manage her Type 2 DM, her hyperlipidemia, and her HTN. You have her DM and hyperlipidemia under control as evidenced by laboratory values. You’re still working on her HTN. Given all of her risk factors you want her B/P to be under 130/80. At this time, she is only on ACEI daily for her HTN. She presents to you today for her usual follow-up visit and upon ROS she reveals that she has been having substernal chest tightness periodically. Sometimes occurs with exertion and resolves with rest.What are the differential diagnoses for this case? Provide top 3 with rationale.’
