DAC

AIMS: We sought to compare the complementary prognostic value of exercise treadmill testing (ETT) and coronary computed tomographic angiography (CTA) among patients referred for both exams. METHODS AND RESULTS: We studied 582 patients without known coronary artery disease (CAD) who were clinically referred for ETT and CTA within 6 months. Patients were followed for cardiovascular (CV) death, non-fatal myocardial infarction (MI), or late revascularization (>90 days), stratified by Duke Treadmill Score (DTS) and CAD severity (≥50% stenosis)...

OBJECTIVES: Patients presenting with acute myocardial infarction and angiographically normal coronary arteries (MINCA) represent a diagnostic and a therapeutic challenge. Cardiac computed tomography (CT) allows detection of coronary artery disease (CAD) even in the absence of significant stenosis. We aimed to investigate whether patients suffering from MINCA had a greater coronary plaque burden, as determined by cardiac CT, than a matched group of healthy volunteers. METHODS: Consecutive patients, aged 45 to 70, with MINCA were enrolled in the Stockholm metropolitan area...

PURPOSE OF REVIEW: The left atrial cavity has recently been identified as a potential biomarker for cardiac and cerebrovascular accidents. This review examines the potential of left atrial size and function in predicting cardiovascular disease in the general population and outcomes in coronary artery disease (CAD) patients. RECENT FINDINGS: The atrium is perfused primarily by branches of the proximal left circumflex coronary artery (LCx), and depression of the cavity mechanical performance has been demonstrated in experimental studies during LCx occlusion...

PURPOSE OF REVIEW: Evaluation of left atrial volume is important, as it is a biomarker of cardiovascular disease and outcomes and correlates with diastolic dysfunction severity. Left atrial volume measurements by different imaging modalities, including 2D and 3D echocardiography (2DE and 3DE), cardiac magnetic resonance (CMR) and computed tomography (CT), are reviewed in regard to recent advances, methodology, prognostic value and limitations. RECENT FINDINGS: Left atrial volume assessments correlate well between the different imaging modalities; however, 2DE significantly underestimates left atrial measurements...

PURPOSE OF REVIEW: This narrative review discusses the associations between metabolic and inflammatory diseases, as well as radiotherapy and chemotherapy with coronary heart disease (CHD) and related risk factors, to support (or not) their potential role as CHD equivalents. RECENT FINDINGS: Although not regarded as CHD equivalents, several metabolic and inflammatory disorders are associated with an increased risk of CHD morbidity and/or mortality. These conditions include metabolic syndrome, impaired glucose metabolism, nonalcoholic fatty liver disease, obstructive sleep apnoea syndrome, erectile dysfunction, periodontitis, inflammatory bowel diseases, systemic vasculitis and HIV infection, as well as chemotherapy and radiotherapy...
