“…6,7 Furthermore, most of the patients undergoing coronary angiography have normal angiograms or non-obstructive CAD. 8,9 Hence, further risk stratification strategies are necessary, in particular, in patients undergoing first diagnostic coronary angiography. In our study, the frequency of CAD was higher in patients with fQRS on surface ECG, and fQRS was significantly associated with higher incidence of stenotic CAD and severe CAD.…”

“…6 However, as it is an invasive procedure and not free from complications, it should be reasonably performed. 7 Only a small proportion of patients referred for coronary angiography with suspected CAD have the diagnosis of obstructive CAD confirmed by coronary angiography, 8,9 suggesting that better risk stratification strategies are necessary. Significance of fQRS in patients without known vascular diseases and apparent myocardial fibrosis is unknown.…”

BackgroundOnly a small proportion of patients referred for coronary angiography with suspected coronary artery disease (CAD) have the diagnosis of obstructive CAD confirmed by the exam. For this reason, further strategies for risk stratification are necessary.ObjectiveTo investigate the relationship of the presence of fragmented QRS (fQRS) on admission electrocardiogram with angiographically detected CAD and CAD severity in patients without known vascular diseases and myocardial fibrosis, undergoing first diagnostic coronary angiography.MethodsWe enrolled 336 consecutive patients undergoing coronary angiography for suspected CAD. The patients were divided into two groups according to the presence or absence of fQRS on admission. We compared the groups regarding the presence and severity of CAD.ResultsSeventy-nine (23.5%) patients had fQRS on admission. There was not a statistically significant difference between patients with fQRS (41.8%) and non-fQRS (30.4%), regarding the presence of CAD (p = 0.059). However, there was a statistically significant difference between patients with fQRS and non-fQRS regarding the presence of stenotic CAD (40.5% vs. 10.5%, p<0.001) and multi vessel disease (25,3% vs. 5.1%, p<0.001). The frequency of fQRS was significantly higher in patients with SYNTAX score >22 compared to patients with SYNTAX score ≤22.ConclusionsOur findings suggest that fQRS may be an indicator of early-stage myocardial damage preceding the appearance of fibrosis and scar, and may be used for risk stratification in patients undergoing first diagnostic coronary angiography

RESUMO Objetivo: Verificar as estimativas de confiabilidade e viabilidade de uso da versão traduzida e adaptada para uso no Brasil do Multidimensional Fatigue Inventory – 20 em pacientes com doença arterial coronariana crônica. Método: Estudo metodológico. O instrumento foi respondido pelos participantes sem auxílio das pesquisadoras. O tempo de preenchimento foi cronometrado, e as facilidades e dificuldades foram documentadas. A viabilidade de uso foi analisada por meio da aceitabilidade, praticabilidade, efeitos teto e chão. A confiabilidade foi estimada por meio da consistência interna. Resultados: A amostra foi composta de 201 participantes. O escore médio de fadiga foi 51,9 + 14,0. Houve pequena taxa de itens não respondidos (0,65%), embora 30,3% dos participantes solicitaram algum esclarecimento após a leitura das instruções; 37,3% relataram que tiveram dúvida ao responder aos itens, em especial, o 19. O tempo de resposta foi de 4,8 + 1,9 minutos. Não houve efeitos teto e chão. A estimativa de confiabilidade foi adequada. Conclusão: O instrumento necessita de ajustes na redação das instruções e de alguns itens, embora apresente boas estimativas de aceitabilidade e de confiabilidade.

High mortality from cardiovascular diseases, especially coronary artery disease (CAD), represents a major economic burden on healthcare systems. The number of diagnostic coronary angiographies (CAG) is increasing in the Russian Federation. However, routine invasive CAG is not able to determine obstructive coronary artery disease in a considerable number of patients. The rate of intact coronary arteries reaches 42% in the major registries and accounts for 37.9% in our Research Institute. Despite all improvements in the diagnostic algorithms focused on suspected coronary artery disease, stated in the recent international and national guidelines, and the availability of advanced non-invasive diagnostic methods, they do not improve accurate CAG diagnosis of obstructive coronary artery disease. Moreover, the available guidelines contain many contradictions. Therefore, an optimal diagnostic algorithm of significant coronary artery lesions is a subject of discussion. The proposed review discusses all discrepancies concerning the assessment of the pretest probability as well as the proposed non-invasive testing. In addition, the preferred use of non-invasive tests with anatomical assessment (i.e. multispiral computed tomography coronary imaging) rather than functional tests with visualization is stated. This review ensures better understanding of diagnostic strategies for stable coronary artery disease used both in researches and in clinical practice.
