Intensive Blood Pressure Treatment Reduces Cardiovascular Risk in Type 2 Diabetes Patients

A groundbreaking study presented at the American Heart Association's Scientific Sessions 2024 has demonstrated that an intensive approach to lowering systolic blood pressure in people with Type 2 diabetes can significantly reduce the risk of major cardiovascular events. The Blood Pressure Control Target in Diabetes (BPROAD) Study, conducted in China, involved nearly 13,000 adults with Type 2 diabetes and high systolic blood pressure.

The study, led by Dr. Guang Ning of Shanghai Jiao Tong University School of Medicine, compared two treatment approaches: an intensive regimen aiming for systolic blood pressure below 120 mm Hg, and a standard approach targeting below 140 mm Hg. Over a follow-up period of up to five years, participants in the intensive treatment group showed a 21% lower relative risk of major cardiovascular events, including non-fatal heart attacks, strokes, hospitalized heart failure, and cardiovascular death.

These findings are particularly significant given that people with Type 2 diabetes are twice as likely to have high blood pressure compared to those without diabetes. The study's results suggest that more aggressive blood pressure management could have substantial benefits for this high-risk population. Dr. Ning stated, "These findings provide strong support for a more intensive systolic blood pressure target in people with Type 2 diabetes for the prevention of major cardiovascular events."

While the intensive treatment group did experience a higher incidence of adverse events such as symptomatic hypotension and hyperkalemia, the overall rate of serious adverse events was similar between the two groups. This suggests that the benefits of intensive blood pressure control may outweigh the risks for many patients with Type 2 diabetes.

The implications of this study could be far-reaching, potentially influencing future clinical practice guidelines for blood pressure management in diabetic patients. However, the researchers note that further studies may be needed to identify which patients are most likely to benefit from intensive treatment with the lowest risk of harm.

As the global prevalence of Type 2 diabetes continues to rise, these findings offer a promising avenue for reducing the burden of cardiovascular disease in this high-risk population. Healthcare providers may need to reassess their approach to blood pressure management in diabetic patients, considering more aggressive treatment targets to improve cardiovascular outcomes.
