High blood pressure has long been called the “silent killer” because many people feel perfectly healthy while damage quietly builds inside their arteries. In recent years, doctors have debated whether lowering blood pressure below 120 mm Hg provides stronger protection against heart attacks and strokes than the traditional target of under 140 mm Hg. Some large studies suggest aggressive blood pressure control can significantly reduce cardiovascular events and even lower the risk of death. However, pushing blood pressure too low may also increase side effects like dizziness, kidney strain, and fainting, especially in older adults. That leaves many patients wondering whether their treatment goals are protecting their health or creating new risks.
