I have been diagnosed with hypertension, and have secondary pulmonary hypertension also Systemic Lupus and COPD. I am having blood pressure readings lately example: 113/109 pulse 68. The systolic is in the normal range but the diastolic is constantly high. I am on BP meds; Cartia XT 240mg; Dyazide 37.5/25mg; Plaqvix 75 mg; Vytorin 20/10mg. Any ideas why I could be having the high dyastolic number? Thanks for your help.
