A Three-Year Observational Study of the Prevalence of Left Ventricular Diastolic Dysfunction in Asymptomatic Individuals With Cardiovascular Risk Factors.

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
backgroundLeft ventricular diastolic dysfunction (LVDD) precedes heart failure and may remain undetected in asymptomatic individuals. Early identification is particularly relevant in populations with cardiometabolic risk factors, where subclinical LVDD could refine risk stratification and guide preventive strategies.
objectiveTo determine the prevalence of clinically significant LVDD (grade II-III) among asymptomatic adults aged 51-70 years and to compare its burden across major cardiovascular risk groups.
methodsThis retrospective cross‑sectional study analyzed 10,434 transthoracic echocardiograms performed over three years (between 1
resultsClinically significant LVDD was present in 102 healthy controls (3.7%, 95% CI: 3.0-4.5). Prevalence was higher in hypertension (13.1%, 95% CI: 11.4-15.0), diabetes mellitus (10.9%, 95% CI: 9.0-13.1), and combined hypertension plus diabetes (29.1%, 95% CI: 24.4-33.8). The highest prevalence occurred in severe obesity (53.5%, 95% CI: 34.1-72.2). LVDD prevalence increased stepwise across escalating cardiometabolic risk profiles.
conclusionClinically significant LVDD is uncommon in asymptomatic individuals without risk factors but substantially more prevalent in those with hypertension, diabetes, or severe obesity. The graded increase across risk categories underscores the cardiometabolic contribution to diastolic dysfunction. While routine screening of all asymptomatic individuals is not supported, targeted evaluation of high‑risk groups warrants further prospective investigation.
