Resistant hypertension is a condition where blood pressure remains persistently elevated despite treatment with three or more antihypertensive medications. Complications of resistant hypertension include an increased risk of cardiovascular events such as heart attacks and strokes.
It can damage vital organs like the heart, kidneys, and eyes, contributing to heart failure, chronic kidney disease, and vision problems. Uncontrolled hypertension also raises the likelihood of aortic aneurysms and peripheral artery disease.
