No, your not the only one. I’m extremely concerned as well since most AI’s list side effects that can damage the heart. My Oncologist looked at me like I was crazy so I took it upon myself to find a cardiologist. I’ve gotten a heart calcium score after some scans for other stuff showed calcium. I’m refusing anything until I get clearance from a cardiologist. I had my appointment last week. He scheduled a chemical stress test & an ultrasound to check the abdominal aorta on 11/28. He said he can’t tell if there is any blockage or arteries that have been blocked until the stress test. After testing we’ll evaluate which meds would be best for my ER/PR+ DCIS depending on the results. I’m passing on radiation after a lumpectomy so I think the AI’s would be beneficial as an added precaution. If your hearts not ok then there’s not much point in treatments that are going to make that worse. Without your heart you’ve got nothing & with my family’s terrible cardiac history I had to be my own advocate………AGAIN! I don’t trust the “here take a pill” & the rest be damned mentality. I also have Osteoporosis so I’m looking into Osteo Strong instead of another pill.
