Hello! Thank you for asking on HCM! Regarding your concern, I would recommend going to the ER for a careful physical examination, a resting ECG and a chest x ray. You need to perform some tests (like a complete blood count, kidney and liver function tests, thyroid hormone levels, fasting glucose, blood electrolytes, blood lipid profile, etc.), to exclude possible causes of a secondary hypertension. I would like to explain that uncontrolled high blood pressure can lead to hypertensive encephalopathy (which is a brain dysfunction from the disruption of the blood-brain barrier from high blood pressure), with a similar symptomatology. If not treated, it can lead to seizures and possible intracranial hemorrhage or stroke. Other complications of chronic uncontrolled high blood pressure, are progressive damage to the blood vessels, which leads to cardio-vascular disease. I recommend taking sublingual Captopril which will help reduce your blood pressure, while going to the ER. Hope to have been of help! Best regards, Dr. Iliri
