Hello and thank you for using HCM.I carefully read your question and I understand your concern.
I will try to explain you something and give you my opinion.
You should know that we talk about hypertension if we have mean value that exceeds 140 / 90 mmHg.A person might have high value during emotional and physical strees so its mandatory to judge on mean values.
Hypertension is divided into two groups.
Essential hypertension is a chronic disease, usauly in older ages.It has not an identified cause and it should be treated all live long.
Secondary hypertension is common in younger ages.It means that its a secondary couse of it.This might be a
renal disease, an endocrine problem or a cardiovascular anomaly.
So , if I was your treating doctor I will recommend some examination like an electrocardiogram , a cardiac echo to evaluate heart function and walls , a full blood analyze , an abdominal echo to evaluate renal structure, your urinary chatecolamins and of course a holter pressure monitoring to evaluate your values during day and night.
After all this we can better judge what we are dealling whith and how to treat it.
If you didn't have high values before, it doesn't mean that you would never have, it might happen and we should find the couse if it is any.
Hope I was helpfull.
Best regards , Dr.Ervina.
