Key Takeaways

  • Intensive SBP management to ≤120 mmHg reduced major cardiovascular events by 21% in type 2 diabetes patients compared to standard treatment.
  • The BPROAD Study involved nearly 13,000 adults with type 2 diabetes and high SBP across 145 sites in China.

Reducing systolic blood pressure to less than 120 mmHg lowered the risk of major cardiovascular events for most people with diabetes in the BPROAD trial.

An intensive treatment regimen to lower high systolic blood pressure (SBP) achieved a notable reduction in the risk of cardiovascular disease (CVD) in adults with type 2 diabetes (T2D), according to new late-breaking science presented at the American Heart Association (AHA) Scientific Sessions 2024.1

The Blood Pressure Control Target in Diabetes (BPROAD) Study, involving nearly 13,000 adults with T2D and high SBP in China, evaluated the effect of lowering SBP to ≤120 mmHg on the risk of major cardiovascular events, including non-fatal heart attacks, strokes, hospitalized heart failure, or death due to CVD.

“We found that for most people with T2D, lowering systolic blood pressure to less than 120 mmHg reduced the risk of major cardiovascular events,” lead investigator Guang Ning, MD, PhD, a professor at Ruijin Hospital at Shanghai Jiao Tong University School of Medicine, said in a statement.2 “These findings provide strong support for a more intensive systolic blood pressure target in people with T2D for the prevention of major cardiovascular events.”

Nearly three-quarters of adults with T2D experience high blood pressure, according to data from the Centers for Disease Control and Prevention (CDC).3 Lifestyle modification and therapeutic intervention are recommended for people with consistently raised blood pressure levels, as lack of management can increase the risk of adverse CV outcomes.

BPROAD enrolled 12,821 adults at 145 study sites in 25 provinces or municipalities across mainland China—participants had T2D, elevated SBP, and an increased risk of cardiovascular disease.1 The criteria for elevated SBP were ≥140 mmHg without hypertensive medication or ≥130 mmHg and receipt of ≥1 anti-hypertensive medication.

The study population had an average of 64 years and was approximately 45% women, with 22.5% self-reporting a history of CVD. Approximately half (n = 6414) were enrolled in the intensive treatment group (≤120 mmHg) and half (n = 6407) were enrolled in the standard treatment group (≤140 mmHg).

Upon analysis, the mean SBP levels in participants at the 4-year visit were 120.6 mmHg in the intensive treatment group and 132.1 mmHg in the standard treatment group. Those receiving the intensive treatment regimen experienced a 21% lower relative risk of major cardiovascular events during the follow-up period, compared with those on standard treatment.

Occurrence of non-fatal stroke, non-fatal heart attack, hospitalization or treatment for heart failure, or cardiovascular death was observed in 393 participants in the intensive treatment regimen and 492 in the standard treatment regimen, correlating to 1.65% and 2.09% per year, respectively.

Serious adverse events, including hospitalization, were typically similar between treatment groups, according to Ning and colleagues. However, the team reported a more frequent occurrence of symptomatic hypotension and hyperkalemia in the intensive treatment regimen group.

In the release, Ning indicated these findings remained consistent with a study of patients without hypertension but not T2D reporting a significant 27% reduction in the incidence of CVD with an intensive SBP regimen.2

“Future clinical practice guidelines will hopefully consider these results when making recommendations for blood pressure targets for people with T2D,” Ning added.2 “Beneficial future research could focus on profiling those with the largest benefit and the lowest harm in an intensive blood pressure treatment group.”
