coronary artery calcium scoring (cacs) is a reasonable test for patients with the possibility of atherosclerosis. it can also be used for reclassifying the coronary artery disease (cad) to the high-risk status by higher cacs and subsequently modifying the management of the patients.the purpose of this study was to investigate the association of cacs to the severity of coronary artery disease in...
BACKGROUND Coronary computed tomography angiography (coronary CTA) can prognosticate outcomes in patients without modifiable risk factors over medium term follow-up. This ability was driven by major adverse cardiovascular events (MACE). OBJECTIVE Determine if coronary CTA could discriminate risk of mortality with longer term follow-up. In addition we sought to determine the long-term relation...
BACKGROUND Although atrial fibrillation (AF) has been linked to underlying coronary artery disease (CAD), data supporting this association have been based on ECG and clinical history for the definition of CAD rather than direct visualization of atherosclerosis. METHODS AND RESULTS The prevalence of CAD among patients with paroxysmal or persistent AF and without history of CAD was evaluated us...
Introduction. The purpose of this study is to investigate chest pain evaluations after initial coronary computed tomography angiography (CCTA) based upon coronary artery disease (CAD) burden. Methods. CCTA results of 1,518 patients were grouped based on the CCTA results into no CAD, nonobstructive CAD (<50% maximal diameter stenosis), or obstructive CAD (≥50% stenosis). Chest pain evaluation af...
OBJECTIVE In this study, we evaluated obesity as a single risk factor for coronary artery disease (CAD), along with the synergistic effect of obesity and other risk factors. METHODS A retrospective study of 7,567 patients admitted to hospital for chest pain from 2005 to 2014 and underwent cardiac catheterization. Patients were divided into two groups: obese and normal with body mass index (BM...
BACKGROUND Previous studies have demonstrated the relevance of left coronary artery dominance in the outcome and prognosis of obstructive coronary artery disease (CAD). However, no studies have investigated the influence of coronary vessel dominance on non obstructive CAD. The aim of this study was to establish the association of left and mixed dominance of the major epicardial arteries with th...
BACKGROUND The value of ≥64-slice coronary CT angiography (CCTA) to determine odds of cardiac death or non-fatal myocardial infarction (MI) needs further clarification. METHODS We performed a systematic review and meta-analysis using publications reporting events/severity of coronary artery disease (CAD) in patients with suspected CAD undergoing CCTA. Patients were divided into: no CAD, non-o...
Introduction: Obstructive coronary artery disease (CAD) in proximal segments is associated with a poor prognosis. However, the contribution of plaque location to major adverse cardiovascular events (MACE) among patients nonobstructive CAD not well defined. We examined MACE risk relation non-obstructive by CT angiography (CCTA).
BACKGROUND Myocardial infarction (MI) patients without obstructive coronary artery disease (CAD) are at increased risk for recurrent ischemic events, but angina frequency post-MI has not been described. METHODS AND RESULTS Among MI patients who underwent angiography, we assessed angina at baseline, 1, 6, and 12 months using the Seattle Angina Questionnaire (SAQ). A hierarchical repeated measu...
INTRODUCTION Troponin elevation is an independent risk factor for mortality, but the prognosis of patients with troponin elevation and non-obstructive coronary artery disease (CAD) is unknown. Recent data have suggested an increased risk of mortality. This study was performed to further investigate the outcomes of troponin-positive patients with obstructive and non-obstructive CAD. METHODS A ...
