Abstract

The prevalence and severity of obesity have increased over recent decades, reaching worldwide epidemics. Obesity is associated to coronary artery disease and other risk factors, including hypertension, heart failure and atrial fibrillation, which are all increased in the setting of obesity. Several noninvasive cardiac imaging modalities, such as echocardiography, cardiac computed tomography, magnetic resonance and cardiac gated single-photon emission computed tomography, are available in assessing coronary artery disease and myocardial dysfunction. Yet, in patients with excess adiposity the diagnostic accuracy of these techniques may be limited due to some issues. In this review, we analyze challenges and possibilities to find the optimal cardiac imaging approach to obese population.

Resumen

La prevalencia y la severidad de la obesidad se han incrementado en las últimas décadas, alcanzando el grado de epidemia a nivel mundial. La obesidad se asocia a enfermedades arteriales coronarias y otros factores de riesgo, incluyendo hipertensión, insuficiencia cardiaca y fibrilación auricular, que se incrementan en los casos de obesidad. Se dispone de diversas técnicas de imagen cardiaca no invasivas, tales como ecocardiografía, tomografía computarizada cardiaca, resonancia magnética y tomografía computarizada de emisión de fotón único cardiaca, para evaluar las enfermedades arteriales coronarias y la disfunción miocárdica. Sin embargo, en pacientes con exceso de adiposidad, la precisión diagnóstica de estas técnicas puede verse limitada debido a diversas cuestiones. En esta revisión analizamos las dificultades y las posibilidades de encontrar la técnica de imagen óptima en la población obesa.
