Abstract
Objective

To assess the usefulness of cardiac stress magnetic resonance imaging (MRI) with adenosine in the detection of ischemic heart disease in patients with a low pretest probability of disease.

Material and methods

We used the probability ratio to analyze the usefulness of cardiac stress MRI in a selection of patients with a low pretest probability of ischemic heart disease (low or moderate cardiovascular risk, atypical chest pain, or absence of prior ischemic heart disease).

Results

We included 295 patients followed up for a median of 28 (19–36) months. A total of 60 patients had an event. Cardiac stress MRI was more useful in patients with a low pretest probability: atypical chest pain (probability ratio [PR] positive 8.56), absence of prior ischemic heart disease (PR positive 4.85), and low or moderate cardiovascular risk (PR positive 3.87).

Conclusions

Cardiac stress MRI can be useful in the diagnosis of ischemic heart disease in patients with a low pretest probability.

Resumen
Objetivo

Evaluar la utilidad de la resonancia magnética cardiaca de estrés (RMCE) con adenosina en la detección de cardiopatía isquémica en pacientes con baja probabilidad preprueba.

Material y métodos

Se evaluó la utilidad de la RMCE en una selección de pacientes con baja probabilidad preprueba (riesgo cardiovascular bajo o moderado, dolor torácico atípico o ausencia de cardiopatía isquémica previa) mediante el uso del cociente de probabilidad.

Resultados

Se incluyeron 295 pacientes, con un seguimiento de 28 (19-36) meses. Un total de 60 pacientes presentaron un evento. Se observó una mayor utilidad de la RMCE en los pacientes con una probabilidad preprueba baja: dolor torácico atípico (cociente de probabilidad [CP] positivo 8,56), ausencia de cardiopatía isquémica previa (CP positivo 4,85) y riesgo cardiovascular bajo o moderado (CP positivo 3,87).

Conclusiones

La RMCE puede ser una técnica útil en el diagnóstico de cardiopatía isquémica en pacientes con baja probabilidad preprueba.
