Why the study?

While the benefits of reducing blood pressure are established, the optimal blood pressure level to maintain remains debatable.

Does intensive blood pressure control reduce major adverse cardiovascular events in patients with hypertension compared to standard blood pressure control?

Population

37,249 subjects from 12 randomized controlled trials

Comparison

Intensive blood pressure control vs standard blood pressure control

Design

Systematic review and meta-analysis of randomized controlled trials

Key result

Intensive blood pressure control reduced major adverse cardiovascular events by 20% (RR 0.80) compared to standard control, yielding an absolute risk reduction of 1.5%.

Overview

Supports intensive targets with monitoring for hypotension and AKI; confirms consistent RCT evidence for lower BP goals.

Study Design

Type

Meta-Analysis (n=37,249)

Structured PICO

Does intensive blood pressure control reduce major adverse cardiovascular events in patients with hypertension compared to standard blood pressure control?

P
Population
37,249 adult participants from 12 randomized controlled trials comparing intensive versus standard blood pressure control, followed for a median of 3.3 years.
I
Intervention
Intensive blood pressure control (target blood pressure <130/80 mmHg)
C
Comparator
Standard blood pressure control (target blood pressure of 140 to 150/90 mmHg)
O
Outcome
Major adverse cardiovascular events (MACE), a composite measure including all-cause mortality, cardiovascular mortality, myocardial infarction, stroke, heart failure, and adverse eventscomposite

Main Result

Relative Risk: 0.8 (95% CI 0.73–0.88)

Absolute Risk Reduction: 1.5%

Number Needed to Treat: 67

p-value: p=<0.001

Intensive blood pressure control significantly reduces the risk of major adverse cardiovascular events but is associated with an increased risk of adverse events such as hypotension and acute kidney injury.

Limitations

  • Definitions of 'intensive' and 'standard' blood pressure control varied across included studies.
  • Individual patient data were not available, limiting the ability to explore potential effect modifiers at the patient level.
  • Most trials had relatively short follow-up durations (median 3.3 years), leaving the long-term sustainability of benefits and harms uncertain.
  • Lack of blinding of participants and personnel in the included trials.
  • Exclusion of trials without individual endpoint data
  • Lack of blinding of participants and personnel in included trials
  • Varying definitions and adjudication of adverse events across studies
  • Substantial heterogeneity in adverse event rates

Cite This Study

Rizwanullah et al. (2025) conducted a meta-analysis in Hypertension (n=37,249). Intensive blood pressure control vs. Standard blood pressure control (Target 140-150/90 mmHg) was evaluated on Major adverse cardiovascular events (MACE) composite including cardiovascular death, nonfatal myocardial infarction, and nonfatal stroke (RR 0.80, 95% CI 0.73-0.88, p=<0.001). Intensive blood pressure control reduced major adverse cardiovascular events by 20% (RR 0.80) compared to standard control, yielding an absolute risk reduction of 1.5%.
