Could too low blood pressure in old age increase mortality?
With increasing age, blood pressure rises as a consequence of arterial stiffness, caused by the biological process of ageing and arteries becoming clogged with fatty substances, otherwise known as arteriosclerosis. Large hypertension trials showed that lowering blood pressure in people over 60 is beneficial and lowers the risk of heart attacks, stroke, and all-cause mortality, even in people over 80. Since arterial hypertension, high blood pressure in the arteries, is the most important preventable cause of cardiovascular disease, it seemed obvious for at least two decades to treat hypertension without restrictions even patients over 60.
