## TL;DR

This study evaluates how well non-invasive exercise tests can identify high-risk heart pathways in patients with WPW syndrome, finding they are good at ruling out risks but not fully reliable alone.

## Contribution

The study provides a systematic review and meta-analysis of non-invasive exercise test accuracy for detecting high-risk accessory pathways in WPW syndrome.

## Key findings

- Non-invasive exercise tests have high sensitivity (92.7%) but low specificity (28.1%) for detecting high-risk accessory pathways in WPW.
- A negative test result reduces the likelihood of a high-risk pathway by about four times.
- Results were consistent when analyzing only pediatric patients.

## Abstract

A síndrome de Wolff-Parkinson-White (WPW) é caracterizada por pré-excitação ventricular, que pode levar a eventos arrítmicos graves, como taquicardia supraventricular e fibrilação atrial pré-excitada. O valor diagnóstico de testes ergométricos não invasivos para detectar vias acessórias de alto risco permanece inconsistente na literatura.

Avaliar a precisão diagnóstica de testes ergométricos não invasivos em comparação com os estudos eletrofisiológicos invasivos (EEF) para identificar vias acessórias de alto risco na síndrome de WPW.

De acordo com as diretrizes do PRISMA-DTA, foi realizada uma busca abrangente nas bases de dados PubMed, Scopus e Web of Science. Estudos elegíveis avaliaram a sensibilidade, especificidade e razões de verossimilhança de testes ergométricos não invasivos em pacientes com WPW, utilizando EEF como padrão de referência. Para a metanálise, foi aplicado um modelo bivariado de efeitos aleatórios.

Seis estudos, totalizando 765 pacientes, atenderam aos critérios de inclusão. A sensibilidade combinada foi de 92,7% (IC de 95%: 88,0% – 94,0%), e a especificidade combinada foi de 28,1% (IC de 95%: 23% – 35,1%). A razão de verossimilhança negativa (LR-) de 0,260 (IC de 95%: 0,174 – 0,387) indicou que a presença de uma via acessória de alto risco é aproximadamente quatro vezes menos provável após um resultado de teste negativo. A análise de sensibilidade, restrita a pacientes pediátricos, demonstrou resultados consistentes.

Testes ergométricos não invasivos demonstram uma utilidade diagnóstica razoável para descartar vias de alto risco na síndrome de WPW. No entanto, é necessária cautela ao utilizar esses testes como critérios independentes para estratificação de risco.

Wolff-Parkinson-White (WPW) syndrome is characterized by ventricular pre-excitation, which can lead to severe arrhythmic events such as supraventricular tachycardia and pre-excited atrial fibrillation. The diagnostic value of non-invasive exercise tests in detecting high-risk accessory pathways remains inconsistent in the literature.

To evaluate the diagnostic accuracy of non-invasive exercise tests compared to invasive electrophysiological studies (EPS) for identifying high-risk accessory pathways in WPW syndrome.

Following PRISMA-DTA guidelines, a comprehensive search was conducted in PubMed, Scopus, and Web of Science databases. Eligible studies assessed the sensitivity, specificity, and likelihood ratios of non-invasive exercise tests in WPW patients, using EPS as the reference standard. A bivariate random-effects model was applied for meta-analysis.

Six studies, comprising a total of 765 patients, met the inclusion criteria. The pooled sensitivity was 92.7% (95% CI: 88.0% – 94.0%), while the pooled specificity was 28.1% (95% CI: 23% – 35.1%). A negative likelihood ratio (LR-) of 0.260 (95% CI: 0.174 – 0.387) indicated that the presence of a high-risk accessory pathway is about four times less likely after a negative test result. Sensitivity analysis restricted to pediatric patients showed consistent results.

Non-invasive exercise tests demonstrate a reasonable diagnostic utility for ruling out high-risk pathways in WPW syndrome. However, caution is advised when using these tests as standalone criteria for risk stratification.
