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. Hypertension is divided in two groups: essential or idiopathic hypertension without an identifiable cause and secondary hypertension, usually in young ages, meaning that is a secondary cause of it. This cause might be a renal disease, an endocrine problem, a cardiovascular pathology. As you explain, your mother had a heart attach before.This might have caused a little stress on you and this high values might be normal. The fact that it is a family history with cardiovascular problem should make us much alert with you even your young age. If I was your treating doctor i will recommend a full check up with blood test analyze, a electrocardioram, echo-cardiography and a pressure holter monitoring to check your mean values. Only after this we can be sure if is just a stressed period or something else. Hope I was helpful. Best regards.
