I have had Coronary Artery Disease for many years, have had catheter surgery, bypass grafts and stents. Part of the problem was high blood pressure for which three separate meds were prescribed. Then, in November, 2010, along came Parkinson's. I soon devloped weakness, light headedness and a tendency to faint on getting up. This cause was identified as low blood pressure which is one of the symptoms of PD. I stopped taking two of the hypertension meds, Zetia and Lisinopril, and let Parkie control the blood pressure. He has done a great job. Blood pressure has stayed in an acceptable range. No episodes, no angina. I no longer carry nitro. I hope this is not "tempting fate", telling this, but I'm curious to know if there are similar stories out there,
