Many patients undergo elective coronary angiography without preprocedural stress testing that may be suitable if performed in patients with more angina pectoris or more frequently identified obstructive coronary artery disease (CAD). Patients in the National Cardiovascular Data Registry CathPCI Registry undergoing elective coronary angiography from July 2009 to April 2013 were assessed for diff...

Cytochrome P450 (CYP)-derived epoxyeicosatrienoic acids (EETs) exhibit potent cardiovascular protective effects in preclinical models, and promoting the effects of EETs has emerged as a potential therapeutic strategy for coronary artery disease (CAD). The relationship between circulating EET levels and CAD extent in humans, however, remains unknown. A panel of free (unesterified) plasma eicosan...

Abstract Background/Introduction Patients with non-obstructive CAD are at risk for future ASCVD events. Coronary angiography FFR distinguishes obstructive from CAD, however, it is unknown how assessment impacts subsequent lipid management in vs CAD. Purpose Examine patterns intensification of lipid-lowering therapy after those Methods Records were reviewed patients a single institution who unde...

BACKGROUND The contribution of plaque extent to predict cardiovascular events among patients with nonobstructive and obstructive coronary artery disease (CAD) is not well defined. Our objective was to evaluate the prognostic value of plaque extent detected by coronary computed tomography angiography. METHODS AND RESULTS All consecutive patients without prior CAD referred for coronary computed...

BACKGROUND AND OBJECTIVES Advanced glycation end-products (AGEs) contribute to the development of atherosclerosis. We investigated whether serum AGEs are related to the presence or severity of coronary artery disease (CAD), and explored the association between serum AGEs and arterial stiffness according to diabetes status in patients suspected of having CAD. SUBJECTS AND METHODS The measureme...

IMPORTANCE Prior studies have shown that physicians in New York State (New York) perform twice as many cardiac catheterizations per capita as those in Ontario for stable patients. However, the role of patient selection in these findings and their implications for detection of obstructive coronary artery disease (CAD) are largely unknown. OBJECTIVE To evaluate the extent of obstructive CAD and...

BACKGROUND Currently available noninvasive tests to risk stratify patients for obstructive coronary disease result in many unnecessary cardiac catheterizations, especially in women. We sought to compare the diagnostic accuracy of presenting symptoms, noninvasive test results, and a gene expression score (GES) in identifying obstructive coronary artery disease (CAD) according to gender, using qu...

BACKGROUND The prevalence of coronary artery disease (CAD) in valvular patients is similar to that of the general population, with the usual association with traditional risk factors. Nevertheless, the search for obstructive CAD is more aggressive in the preoperative period of patients with valvular heart disease, resulting in the indication of invasive coronary angiography (ICA) to almost all ...

BACKGROUND The use of invasive coronary angiography in stable ischemic heart disease (IHD) varies widely. OBJECTIVE To validate the 2012 appropriate use criteria for diagnostic catheterization by examining the relationship between the appropriateness of cardiac catheterization in patients with suspected stable IHD and the proportion of patients with obstructive coronary artery disease (CAD) a...

INTRODUCTION Coronary artery disease (CAD) in diabetes mellitus (DM) is often widespread when diagnosed. Non-invasive coronary calcium scoring and coronary CT angiography (CAC-score/CCTA) are accurate in the detection of CAD. This study compared CAD characteristics as identified by CCTA between patients with and without DM with atypical chest pain. METHODS CAD was defined as CAC-score >0 and/...
