Aims: Near-infrared spectroscopy (NIRS) is able to quantify cholesterol within coronary arteries by the lipid core burden index (LCBI). We studied the prognostic value of NIRS-derived LCBI in patients with coronary artery disease (CAD) for adverse cardiac outcome during long-term follow-up. Methods and results: During 2009-2013, NIRS was performed in a non-culprit artery of 275 patients undergoing coronary angiography for acute coronary syndrome (ACS) or stable angina...

A 50-year-old man experienced cardiac arrest. The patient underwent standard cardiopulmonary resuscitative measures for approximately 20 minutes before spontaneous circulation returned. He was diagnosed with variant angina, and subsequent imaging for evaluation of upper back pain revealed fractures of the fifth through eighth thoracic vertebrae. Multiple thoracic vertebral fractures are extremely rare. Here we report a case of multiple thoracic vertebral fractures as a complication of cardiopulmonary resuscitation...

Alongside the remarkable progress in therapeutic strategies destined to patients with coronary artery disease (CAD), a growing number of patients who suffer from severe and diffuse CAD not amenable for revascularization, continue to experience severe debilitating angina despite optimal medical therapy. The Coronary Sinus (CS) Reducer has emerged as a novel therapeutic strategy for patients with refractory angina pectoris. The Reducer is a stainless steel, balloon-expandable, hourglass shaped device implanted percutaneously through the right internal jugular vein in the coronary sinus...

BACKGROUND AND AIMS: We aimed at evaluating the relation of (18)F-sodium fluoride ((18)F-NaF) uptake on positron emission tomography (PET) to coronary atherosclerosis detected and assessed by computed tomography (CT). METHODS: Thirty-two patients with one or more coronary atherosclerotic lesions detected on cardiac CT underwent (18)F-NaF PET/CT. Each coronary atherosclerotic lesion was evaluated on CT angiography for plaque types (calcified plaque [CP], non-calcified plaque [NCP], partially calcified plaque [PCP]), and the presence of CT-based high-risk features (minimum CT density <30 Hounsfield units and vascular remodeling index >1...

BACKGROUND: Ischemia, in the absence of obstructive coronary artery disease, is prevalent in women, and associated with increased risk for major cardiovascular events. Coronary microvascular dysfunction is prevalent in these patients, and associated with impaired diastolic function. Despite our general understanding, however, optimal treatment of this cohort remains elusive. METHODS: To address this knowledge gap, we performed an open-label treatment trial to assess whether phosphodiesterase type 5 inhibition improves coronary microvascular perfusion and diastolic function in women with signs and symptoms of ischemia but no evidence of obstructive coronary artery disease...

Patients presenting to the emergency department with acute chest pain, negative conventional troponin and electrocardiogram require serial testing to rule out acute coronary syndrome (ACS). We studied the association of highly sensitive troponin (hsTn) I with vulnerable plaque features as detected by coronary dual source computed tomography angiography (DSCTA) and determined whether hsTn I at the time of presentation combined with early DSCTA could improve classification of patients as high-risk or low risk for ACS...

OBJECTIVES: The purpose of this study was to evaluate the prognostic value of sequential hybrid imaging strategy in which positron emission tomography (PET) perfusion imaging is performed selectively in patients with suspected obstructive coronary artery disease (CAD) on coronary computed tomography angiography (CTA). BACKGROUND: Coronary CTA is an accurate diagnostic test for excluding obstructive CAD. However, the positive predictive value is suboptimal. METHODS: We investigated 864 consecutive symptomatic patients with intermediate probability of CAD who adhered to the sequential imaging approach...

BACKGROUND AND AIMS: Many coronary artery disease (CAD) patients exhibit chronic low-grade inflammation. Carotenoids are anti-oxidants with potential anti-inflammatory properties. Here, we first assessed relationships between interleukin (IL)-6 and individual carotenoids in plasma from CAD patients. Based on the results, we proceeded to assess anti-inflammatory effects of one carotenoid, lutein, in peripheral blood mononuclear cells (PBMCs) from CAD patients. METHODS: Lutein + zeaxanthin (isomers with lutein being dominant), β-cryptoxanthin, lycopene, α- and β-carotene and IL-6 were measured in plasma from 134 patients with stable angina (SA) and 59 patients with acute coronary syndrome...

INTRODUCTION: Randomized and nonrandomized clinical trials have tried to assess whether or not TMR patients experience an increase in myocardial perfusion. However there have been inconsistencies reported in the literature due to the use of different nuclear imaging modalities to test this metric. The primary purpose of this meta-analysis was to determine whether SPECT, MUGA and PET scans demonstrate changes in myocardial perfusion between lased and non-lased subjects and whether laser type affects myocardial perfusion...

OBJECTIVES: Both Chiari malformation type 1 (CMI, i.e., the idiopathic caudal ectopy of cerebellar tonsils into foramen magnum) and idiopathic intracranial hypertension (IIH) are characterized by reduced intracranial compliance (ICC) due to disturbed circulation of cerebrospinal fluid (CSF). An increasing body of evidence links cardiovascular disease to CSF circulation disturbances. The aim of this study was to explore whether the prevalence of cardiovascular risk factors in patients with CMI or IIH is higher than in the general population...

BACKGROUND: Associations between sleep duration and cardiovascular conditions have been inconsistent. Both short and long sleep duration are associated with increased risk for diabetes, hypertension, obesity, high cholesterol, depression, and overall metabolic dysfunction; all of which are cardiovascular disease risk factors. This study aimed to determine if deficient or excessive sleep duration is associated with cardiovascular conditions. METHODS: Data were obtained from the 2013 Behavioral Risk Factor Surveillance System for the state of Nevada...

OBJECTIVES: Anomalous aortic origin of a coronary artery is uncommon but potentially clinically significant. Manifestations vary from asymptomatic patients to those who present with angina pectoris, myocardial infarction, heart failure, syncope, arrhythmias, and sudden death. We describe our experience with surgical reimplantation and results at midterm follow-up. METHODS: Between February 2003 and July 2016, a total of 13 patients with anomalous origin of the right coronary artery (RCA) from the left sinus underwent surgical reimplantation...

Prediction of coronary events remains elusive. Carotid atherosclerosis may be a surrogate for coronary risk, as carotid and coronary diseases occur simultaneously - albeit at times with a weak association - depending on clinical presentation. We investigated carotid and coronary atherosclerosis in men with new-onset unstable coronary artery disease (CAD) presenting with acute ST-segment elevation myocardial infarction (STEMI) vs. long-standing severe chronic stable angina (CSA). Bilateral carotid artery and 3-vessel coronary artery atherosclerosis burdens were measured within 1 month, respectively, by 3D-volumetric carotid magnetic resonance imaging and coronary angiography-derived modified CASS-50 score...

INTRODUCTION: Platelet activation participate in the development of both coronary artery disease (CAD) and circulating microparticles (MPs). As a commonly used medicine for coronary heart disease, whether aspirin affects the function of MPs remains unclear. AIMS: This study was designed to test MPs from healthy subjects, stable angina (SA) patients before and after aspirin administration were obtained. MPs origins were tested by flow cytometry. Rat thoracic aortas were incubated with MPs (with or without aspirin) to determine the effects of MPs on expression of ERK1/2, JNKs and p38 MAPK...

BACKGROUND: The cholesteryl ester transfer protein inhibitor evacetrapib substantially raises the high-density lipoprotein (HDL) cholesterol level, reduces the low-density lipoprotein (LDL) cholesterol level, and enhances cellular cholesterol efflux capacity. We sought to determine the effect of evacetrapib on major adverse cardiovascular outcomes in patients with high-risk vascular disease. METHODS: In a multicenter, randomized, double-blind, placebo-controlled phase 3 trial, we enrolled 12,092 patients who had at least one of the following conditions: an acute coronary syndrome within the previous 30 to 365 days, cerebrovascular atherosclerotic disease, peripheral vascular arterial disease, or diabetes mellitus with coronary artery disease...
