I am a 35 year old female. 4 years a go I was diagnosed with diastolic dysfunction of the left side. I completed a stress test and the cardiologist stated it appeared fine. I did not follow up in a year. Most recently i have been having dizzy spell/feeling light headed. It used to only last a few seconds and accompanied by a very breif period of confusion while I refocused, never lasting more than 30 seconds. Today I woke up and felt bad ( originally blamed it on the extra glass of wine from the night before) but it got worse and I felt off balance. My BP was 140\107 so I went to local urgent care. My bp remained high even after I took lisinopril 20mg (not something I usually take). They did and ekg and it appears that i have left atrial enlargement. My resting heart rate has been on the 100 for the last few months and was 95 during the ekg. Is the left atrial enlargement due to diastolic dysfunction? Or high BP. I feel like my BP is very high but doctors are not concerned by it. I have made an appointment to see a cardiologist in a few weeks but wanted to see if anyone could explain this more to me. I have a medical background but this is outside my scope of practice.
