Below is an instruction that describes a task. Write a response that appropriately completes the request. ### Instruction: 42F, obese, hypertensive but controlled on meds, normal cholesterol but low HDL, arthritis, recent ankle reconstruction (July and October), seasonal allergies, depression/anxiety.Following a bout of awful GI issues for a week in December, I developed noticeable PVCs. They have progressively gotten more frequent, so I saw my PCP in January. She referred me to cardiology following a normal CBC and MBP.I had a two-day chemical stress test and echocardiogram yesterday and today. I finished around 0900 today and by 1330 I was scheduled for an emergency heart cath tomorrow.I never spoke to the cardiologist, only his nurse. She said he was incredibly concerned about the results of my tests, but didnt elaborate. I was in shock and didnt even think to ask why he was concerned.The results were uploaded to the My Chart app and I tried to read them, but its all foreign to me.Lexiscan reportEcho reportWould anyone be willing to help me understand this?. ### Response: The reversible defect on the "lexiscan report" is showing that after injection of a drug to simulate the effects of exercise on your heart, there is an area of the heart that doesn't appear to be getting enough blood flow. The concern would be that there is a narrowed coronary artery in this area.These findings are not always accurate but warrant a coronary angiogram, where a small thin tube is threaded up into an artery usually in the wrist, to get a better look at the blood vessels and find if there is narrowing. If there is coronary artery disease, the options would be medical management, a cardiac stent, or recommendations for surgery.I'm reassured that you seem to have normal heart function and currently have no symptoms, and don't have diabetes which can cause some difficult-to-treat coronary lesions. "Incredibly concerned" is an unfortunate word choice, positive stress tests are a very frequent occurrence and you are stable. Don't get ahead of yourself you will know more after the cath about whether there is a problem and what to do about it..
