I Know There Are Many Possible Conditions, But Just A

I know there are many possible conditions, but just a short list would be helpful...I am a 66 year old female, somewhat overweight and did mostly sedentary office work most of my life. Most exercise was housework, and regular walking on lunch hours and break times. I always had regular checkups and until this past year, did not need any prescription medications. My blood pressure has been running in the 140's over 90 and my cholesterol is high. I am now taking lisinopril and simvistatin and there has been some improvement. But lately I am noticing some shortness of breath on mild exertion and an almost constant mild fluttering sensation in my chest. I will be seeing my doctor in January. Any suggestions?
