Two new studies published in JAMA Internal Medicine suggest that doctors should work together with patients to de-intensify treatment for high blood pressure or diabetes in older people. In some cases, stopping or cutting back on medications can be safer than continuing treatment due to the risk of low blood pressure and sugar levels.
A new Northwestern Medicine study found that blood pressure medication can reduce cardiovascular disease risk, but it cannot undo all previous damage. Middle-aged adults with well-controlled hypertension on medication had a higher risk of end-organ damage compared to those without treatment.

A new study published in the American Journal of Clinical Nutrition found that a DASH-style diet with lean, unprocessed pork as the primary protein source reduced blood pressure and had similar effects when chicken or fish was used instead. The study included 19 participants with elevated high blood pressure and demonstrated the versat...
Astrocytes play a crucial role in maintaining healthy vascular tone by releasing signals to dilate or constrict blood vessels as needed. This basal control helps regulate blood flow and prevent damage from excessive pressure or calcium levels.
A study published in Medical Care found that higher numbers of unique doctors on staff and increased patient appointments were associated with lower rates of blood pressure normalization. The researchers suggest that busier practices may lead to compromised care due to reduced time and attention for patients.
