چکیده

Background: Coronary computed tomography angiography (CCTA) allows for noninvasive coronary artery disease (CAD) phenotyping. Factors related to CAD progression are epidemiologically valuable. Objective: To identify factors associated with CAD progression in patients undergoing sequential CCTA testing. Methods: We retrospectively analyzed 384 consecutive patients who had at least two CCTA studies between December 2005 and March 2013. Due to limitations in the quantification of CAD progression, we excluded patients who had undergone surgical revascularization previously or percutaneous coronary intervention (PCI) between studies. CAD progression was defined as any increase in the adapted segment stenosis score (calculated using the number of diseased segments and stenosis severity) in all coronary segments without stent (in-stent restenosis was excluded from the analysis). Stepwise logistic regression was used to assess variables associated with CAD progression. Results: From a final population of 234 patients, a total of 117 (50%) had CAD progression. In a model accounting for major CAD risk factors and other baseline characteristics, only age (odds ratio [OR] 1.04, 95% confidence interval [95%CI] 1.01-1.07), interstudy interval (OR 1.03, 95%CI 1.01-1.04), and past PCI (OR 3.66, 95%CI 1.77-7.55) showed an independent relationship with CAD progression. Conclusions: A history of PCI with stent placement was independently associated with a 3.7-fold increase in the odds of CAD progression, excluding in-stent restenosis. Age and interstudy interval were also independent predictors of progression. Fundamento: Angiografia coronariana por tomografia computadorizada (ACTC) permite fenotipagem não invasiva da doença arterial coronariana (DAC). Fatores relacionados à progressão da DAC têm valor epidemiológico. Objetivo: Identificar os fatores associados com a progressão da DAC em pacientes submetidos à avaliação sequencial por ACTC. Métodos: Nós analisamos retrospectivamente 384 pacientes consecutivos que apresentavam pelo menos duas avaliações por ACTC entre dezembro de 2005 e março de 2013. Devido às limitações na quantificação da progressão da DAC, os pacientes que haviam sido submetidos previamente à revascularização cirúrgica ou intervenção coronariana percutânea (ICP) entre as avaliações foram excluídos. A progressão da DAC foi definida como qualquer aumento no escore adaptado de estenose segmentar (calculado com utilização do número de segmentos afetados e gravidade da estenose) em todos os segmentos coronarianos sem stent (restenose intra-stent foi excluída da análise). Regressão logística stepwise foi utilizada para avaliar as variáveis associadas com a progressão da DAC. Resultados: De uma população final de 234 pacientes, um total de 117 (50%) pacientes apresentaram progressão da DAC. Em um modelo considerando os principais fatores de risco para DAC e outras características basais, apenas a idade (odds ratio [OR] 1,04, intervalo de confiança de 95% [IC95%] 1,01-1,07), intervalo entre avaliações (OR 1,03, IC95% 1,01-1,04) e ICP prévia (OR 3,66, IC95% 1,77-7,55) mostraram uma relação independente com a progressão da DAC. Conclusões: Uma história de ICP com implante de stent esteve independentemente associada a um aumento de 3,7 vezes na chance de progressão da DAC, excluindo a restenose intra-stent. Idade e intervalo entre avaliações também foram preditores independentes de progressão.

Usefulness of Coronary Computed Tomography Angiography Evaluating the Clinical Importance of Coronary Artery Calcium and Noncalcified Plaque in Asymptomatic Patients

Direct noninvasive assessment of the characteristics of coronary atherosclerotic plaques is important to improve cardiovascular risk stratification and to monitor the course of coronary artery disease. Coronary computed tomography angiography (CCTA) has become an effective tool for noninvasive evaluation of coronary artery calcium and plaque components. Using CCTA, atherosclerotic plaques can b...

Impact of metabolic syndrome on the progression of coronary calcium and of coronary artery disease assessed by repeated cardiac computed tomography scans

BACKGROUND It is not clear how severe metabolic syndrome (MS) affects the development of coronary atherosclerosis. METHODS This was an observational, retrospective cohort study with Koreans who received health check-ups voluntarily. A total of 2426 subjects had baseline and follow-up coronary artery calcium score (CACS) data. Among them, 1079 had coronary computed tomography angiography (CCTA...

Additional value of associating aortic valve calcification to coronary calcium as a gatekeeper for coronary tomography angiography

BACKGROUND Aortic valve calcification shares risk factors with coronary artery disease. Coronary calcium has been used has a gatekeeper to performing coronary tomography angiography. The aim of this study was to evaluate aortic valve calcification as a predictor of obstructive coronary artery disease by computed tomography, and its possible usefulness, alongside with coronary calcium, to improv...

Noninvasive Imaging of Atherosclerotic Plaque Progression: Status of Coronary Computed Tomography Angiography.

The process of coronary artery disease progression is infrequently visualized. Intravascular ultrasound has been used to gain important insights but is invasive and therefore limited to high-risk patients. For low-to-moderate risk patients, noninvasive methods may be useful to quantitatively monitor plaque progression or regression and to understand and personalize atherosclerosis therapy. This...
