I was told last January that I had hypertension. The only tests that were done were some blood tests and the doctor listened to my heart with a stethoscope. I was put on Diovan. I keep reading that hypertension can cause an enlarged heart. How would I know if I have any damage? My readings were 140/92 to as high as 160/100 at the doctor's office and I think it was White coat syndrome. I get very nervous at the doctors... My home readings were normal or high normal range and now with the diovan they are even lower. I have to see the Doctor in March. Should I ask him about doing a stress test or Ekg??
