Introduction

In a groundbreaking revelation presented at the American Heart Association (AHA) Scientific Sessions 2024, researchers have discovered that an intensive blood pressure treatment regimen can significantly lower the risk of cardiovascular disease (CVD) among adults with type 2 diabetes.

The Study

This exciting new study, known as the Blood Pressure Control Target in Diabetes (BPROAD) Study, involved nearly 13,000 participants across China. The study aimed to assess the effects of lowering systolic blood pressure (SBP) to 120 mmHg or below on reducing major cardiovascular events, which include non-fatal strokes, heart attacks, heart failure requiring hospitalization, and even death from cardiovascular complications.

Findings

The results are nothing short of remarkable! Lead investigator Dr. Guang Ning, a renowned professor at Ruijin Hospital, stated, “Our findings indicate that most individuals with type 2 diabetes can significantly reduce the risk of major cardiovascular events by achieving an SBP of less than 120 mm Hg.” With almost 75% of people with type 2 diabetes experiencing high blood pressure, this intensive approach could revolutionize treatment recommendations.

Participants and Methods

The BPROAD Study enrolled 12,821 adults diagnosed with type 2 diabetes and elevated SBP across 145 sites in 25 provinces of China. Participants were categorized into either an intensive treatment group, which aimed for SBP levels below 120 mmHg, or a standard treatment group with targets of 140 mmHg or higher.

Results

Participants had an average age of 64, and about 45% were women, with 22.5% reporting a prior history of cardiovascular issues. Results showed that participants in the intensive treatment group achieved average SBP levels of 120.6 mmHg after four years, compared to 132.1 mmHg in the standard treatment group. Even more compelling, those who received intensive treatment experienced a staggering 21% reduction in the relative risk of major cardiovascular events during the study's follow-up period.

Event Rates

The incidence of severe events such as non-fatal strokes, heart attacks, or cardiovascular deaths was reported at 1.65% per year for the intensive treatment group versus 2.09% per year for those receiving standard care. While adverse events were similar between groups, incidences of symptomatic hypotension and high potassium levels were more common in the intensive treatment cohort.

Conclusion and Future Directions

Dr. Ning emphasized the potential impact of these findings on future clinical guidelines, advocating for the integration of intensive SBP targets in treatment protocols for type 2 diabetes. There’s also a call for further research to identify which patients could benefit the most from aggressive blood pressure management without experiencing excessive harm.

This monumental study not only emphasizes the importance of effective blood pressure management in reducing CVD risk among diabetics but also heralds new possibilities for improving healthcare outcomes for millions of individuals living with type 2 diabetes.
