Blood pressure control and improved cardiovascular outcomes in the International Verapamil SR-Trandolapril Study

Area of Science:

• Cardiology
• Hypertension Management
• Clinical Research

Background:

• Uncontrolled blood pressure (BP) is a major cardiovascular risk factor, irrespective of treatment type.
• The impact of BP control consistency on adverse outcomes requires further investigation.

Purpose of the Study:

• To analyze the relationship between the consistency of BP control and cardiovascular outcomes.
• To determine if the proportion of visits with controlled BP (<140/90 mm Hg) influences adverse events.

Main Methods:

• Posthoc analysis of the International Verapamil SR-Trandolapril Study.
• Categorization of 22,576 hypertensive patients with coronary artery disease into four groups based on the percentage of visits with controlled BP.
• Statistical analysis of primary outcomes (death, myocardial infarction, stroke) across BP control consistency groups.

Main Results:

• Cardiovascular risk, including myocardial infarction and stroke, decreased progressively with increasing proportions of visits showing controlled BP.
• Patients with ≥75% of visits with controlled BP had significantly lower adjusted risks for the primary outcome, myocardial infarction, and stroke compared to those with <25% control.
• Baseline BP was not a predictor of outcomes; however, the proportion of visits with controlled BP was strongly associated with mean follow-up systolic BP.

Conclusions:

• Consistent BP control, defined by the proportion of visits with controlled readings, is independently associated with a significant reduction in cardiovascular risk.
• Achieving consistent BP control at most visits provides greater cardiovascular protection than average BP levels alone.
• Healthcare providers should prioritize consistent BP management at every patient visit to mitigate cardiovascular risks.
