Hello and thank you for using HCM. I carefully read your question and I understand your concern. I will try to explain and give you my opinion. We talk about hypertension if we have mean values that exceeds 140/90 mmHg. It is normal to have higher blood pressure values after a physical or an emotional stress, so it is important to judge on mean day and night values. As you explain, you are diagnosed with ischemic heart disease and you have done angioplasty. For this reason your blood pressures should be maintained under 140/90 mmHg. You mention that your mean values are over 140/90 mmHg, so my opinion as a cardiologist is that you should do changes in your medications. We have two strategies : the first one is to increase the existing doses or to add another anti hypertensive medication. You didn t mention the actual dose of nebicard. Its maximal dosage might go up to 10 mg daily, but it is important to know your age and your heart frequency and I recommend to consult it with your cardiologist. Hope I was helpful.Wish you good health. Best Regards.
