My 75 year mother has had high blood pressure for the past 25 years or so. She developed diabetes 5 years ago and is on diet therapy. Her Fasting sugar varies in a range from 7 to 9 mmols. We were told she may have coronary artey disease. However, she has no symptoms. Stress test was inconclusive and we were not keen on angiogram. 3 months ago her cardio found her BP to be 160/80. He increased the dose of her blood pressure medication. Now, her BP readings are between 135-145 (systolic) and 60-65 diastolic. A doctor we consulted for some other problem told me the BP may be too low. He mentioned something about a "J-curve" and that possible harm may come if blood pressures are too low. It could lead to a heart attack or stroke. This he said, may happen if the diastolic BP goes too low. Is this true? Could someone enlighten me on this "J-curve"? Is my mother's BP too low? Should the dose of her BP medication be reduced?

Dear Anna Mae, thank you for your question. I don't know what the physician you mention was referring to with the "J-curve." I think your mother's BP sounds well controlled now and a diastolic BP of 60-65 should be fine. However, I cannot give specific medical advice to you, so I suggest that you speak with her original cardiologist and let that physician manage her BP medications rather than the new physician who referred to the "J-curve."
