Association of blood pressure control with atrial and ventricular ectopy in SPRINT.
Trial report in Open heart, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundPrevious epidemiological studies demonstrated that premature atrial contractions (PACs) and premature ventricular contractions (PVCs) detected by single 12-lead ECGs can predict incident cardiovascular disease and death. The determinants of cardiac ectopy remain unknown, with some evidence that hypertension may contribute.
objectiveTo determine if intensive blood pressure (BP) control reduces the incidence of cardiac ectopy.
methodsWe performed a post-hoc analysis of the Systolic Blood Pressure Intervention trial, which randomised hypertensive participants to standard treatment (BP target <140 mm Hg) or intensive treatment (<120 mm Hg) with ECGs obtained at baseline, 2 years, 4 years and 5 years. The primary outcomes were incidence of ectopy (PACs or PVCs) as coded by Minnesota ECG classification, censoring for pacing, atrioventricular block, pre-excitation or atrial fibrillation/flutter. We performed Cox proportional hazards regression to determine the association of treatment group with outcomes.
resultsThe analysis cohort comprised 3910 participants randomised to standard treatment and 3911 to intensive treatment, of whom 452 had ectopy on baseline ECG. After excluding those with baseline ectopy, there was no significant difference in the incidence of ectopy (incidence rate ratio 0.93 (95% CI 0.81 to 1.05)). There was no significant association between treatment group and ectopy incidence, with an unadjusted Cox HR of 0.93 (95% CI 0.82 to 1.07), and HR of 1 (95% CI 0.81 to 1.25) after adjusting for covariates.
conclusionIntensive BP control did not reduce the incidence of cardiac ectopy in patients with hypertension. Given the variable nature of PAC and PVC burden, further studies with continuous monitoring or more frequent sampling in larger populations are warranted.
