Long-term survival in patients with premature ventricular complexes and no structural heart disease.
Observational study in Open heart, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundPremature ventricular complexes (PVCs) are common and can cause concerns in both patients and their caregivers. In patients with structural heart disease, PVCs are associated with worse clinical outcomes. However, in patients without such disease, the prognostic implications of PVCs are more uncertain.
methodsIn this observational cohort study, we included patients who were diagnosed with PVCs at three major hospitals in Stockholm between 2010 and 2016. All included patients had normal results on echocardiography and stress test, and no history of structural heart disease. The expected survival from the age-matched, sex-matched and calendar year-matched Swedish population was obtained from the Human Mortality Database. Relative survival was estimated using the Ederer II method.
resultsA total of 803 PVC patients were included. Median age was 59 years, and 57% were women. In all, 185 (23%) patients had more than 10 000 PVCs per day and 86 (11%) had more than 20 000 PVCs per day. The observed survival was greater than the expected survival at 1, 5, 10 and 12 years (100% vs 99%, 97% vs 94%, 93% vs 86% and 90% vs 82%, respectively). The relative survival at 1, 5, 10 and 12 years was 100%, 104%, 109% and 111%, respectively. The median follow-up time was 10 years (maximum 14 years).
conclusionsPVC patients without structural heart disease had a favourable long-term survival, exceeding the expected survival of the general population. These results suggest that most PVC patients without structural heart disease may be given a reassuring message.
