Relationship between Obesity and Coronary Artery Disease Defined by Coronary Computed Tomography Angiography

Abstract Background: Although associated with traditional cardiovascular risk factors, it is unclear whether obesity alone is associated with coronary artery disease (CAD). Objective: To investigate the role of obesity as a risk factor for CAD, defined by coronary computed tomography angiography (CCTA). Methods: This study retrospectively included 1,814 patients referred for CCTA in a hospital in São Paulo, from August 2010 to July 2012. CAD was identified by coronary calcium score and presence of coronary stenosis > 50%. Images were analyzed by two specialists, and the coronary findings were compared between obese and non-obese groups. A multivariate analysis model was used to assess obesity as an independent variable for the occurrence of obstructive CAD. Results: Among the study population, mean age was 58.5 +/- 11.5 years, 22.8% were obese (BMI = 30 kg/m2) and 66.3% were male. The prevalence of obstructive CAD was 18.4% in both groups. Obese patients had higher median calcium score compared to non-obese subjects (14.7 vs. 1.4, respectively, p = 0.019). In the multivariate analysis, obesity was not an independent factor for obstructive CAD (coefficient = -0.035, p = 0.102). Conclusion: Although no differences were observed in the prevalence of obstructive CAD between obese and non-obese individuals, coronary calcium scores were significantly in lower the latter group.

Coronary computed tomography angiography in the assessment of acute chest pain in the emergency room.

The coronary computed tomography angiography has recently emerged as an accurate diagnostic tool in the evaluation of coronary artery disease, providing diagnostic and prognostic data that correlate directly with the data provided by invasive coronary angiography. The association of recent technological developments has allowed improved temporal resolution and better spatial coverage of the cardiac volume with significant reduction in radiation dose, and with the crucial need for more effective protocols of risk stratification of patients with chest pain in the emergency room, recent evaluation of the computed tomography coronary angiography has been performed in the setting of acute chest pain, as about two thirds of invasive coronary angiographies show no significantly obstructive coronary artery disease. In daily practice, without the use of more efficient technologies, such as coronary angiography by computed tomography, safe and efficient stratification of patients with acute chest pain remains a challenge to the medical team in the emergency room. Recently, several studies, including three randomized trials, showed favorable results with the use of this technology in the emergency department for patients with low to intermediate likelihood of coronary artery disease. In this review, we show data resulting from coronary angiography by computed tomography in risk stratification of patients with chest pain in the emergency room, its diagnostic value, prognosis and cost-effectiveness and a critical analysis of recently published multicenter studies.

Angiotomografia de coronárias na avaliação da dor torácica aguda na sala de emergência / Coronary computed tomography angiography in the assessment of acute chest pain in the emergency room

A angiotomografia de coronárias emergiu recentemente como uma ferramenta diagnóstica acurada na avaliação da doença arterial coronariana, fornecendo dados diagnósticos e prognósticos que se correlacionam diretamente com os dados fornecidos pela cineangiocoronariografia. Com a evolução tecnológica, permitindo melhora na resolução temporal, espacial, melhor cobertura do volume cardíaco com redução significativa da dose de radiação, somada à necessidade de protocolos de estratificação de risco mais efetivos para pacientes com dor torácica no pronto-socorro, sua aplicação passou a ser testada no cenário da dor torácica aguda, já que cerca de dois terços das angiografias coronarianas invasivas não demonstram doença coronariana obstrutiva significativa. Na prática diária, sem o uso de tecnologias mais eficientes, como a angiotomografia de coronárias, permanece um desafio ao médico do setor de emergência a estratificação segura e eficiente do paciente com dor torácica aguda. Recentemente, vários estudos, incluindo três randomizados, mostraram resultados favoráveis ao uso dessa tecnologia no pronto-socorro para pacientes com baixa a intermediária probabilidade de doença arterial coronariana. Nesta revisão, apresentamos os dados do uso da angiotomografia de coronárias na estratificação de risco de pacientes com dor torácica na sala de emergência, o seu valor diagnóstico, prognóstico e custo-efetividade e uma análise crítica dos recentes estudos multicêntricos publicados.
