BACKGROUND: Heart failure (HF) and dementia are major causes of disability and death among older individuals. Risk factors and biomarkers of HF may be determinants of dementia in the elderly. We evaluated the relationship between biomarkers of cardiovascular disease and HF and risk of dementia and death. Three hypotheses were tested: (1) higher levels of high-sensitivity cardiac troponin T, N-terminal of prohormone brain natriuretic peptide, and cystatin C predict risk of death, cardiovascular disease, HF, and dementia; (2) higher levels of cardiovascular disease biomarkers are associated with increased risk of HF and then secondary increased risk of dementia; and (3) risk of dementia is lower among participants with a combination of lower coronary artery calcium, atherosclerosis, and lower high-sensitivity cardiac troponin T (myocardial injury)...

OBJECTIVES: To assess the diagnostic accuracy of coronary computed tomography angiography (CTA) for bioresorbable vascular scaffold (BVS) evaluation. BACKGROUND: Coronary CTA has emerged as a noninvasive method to evaluate patients with suspected or established coronary artery disease. The diagnostic accuracy of coronary CTA to evaluate angiographic outcomes after BVS implantation has not been well established. METHODS: In the ABSORB II (A Bioresorbable Everolimus-Eluting Scaffold Versus a Metallic Everolimus-Eluting Stent II) study, patients were randomized either to receive treatment with the BVS or everolimus-eluting metallic stent...

OBJECTIVES: This study compared serial changes in coronary percent atheroma volume (PAV) and calcium index (CaI) in patients with coronary artery disease who were treated with and without warfarin. BACKGROUND: Warfarin blocks the synthesis and activity of matrix Gla protein, a vitamin K-dependent inhibitor of arterial calcification. The longitudinal impact of warfarin on serial coronary artery calcification in vivo in humans is unknown. METHODS: In a post hoc patient-level analysis of 8 prospective randomized trials using serial coronary intravascular ultrasound examinations, this study compared changes in PAV and CaI in matched arterial segments in patients with coronary artery disease who were treated with (n = 171) and without (n = 4,129) warfarin during an 18- to 24-month period...

Coronary artery disease is one of the leading causes of death worldwide. The stenotic coronary vessels are generally treated with coronary artery bypass grafts (CABGs), which can be either arterial (internal mammary artery, radial artery) or venous (saphenous vein). However, the different mechanical properties of the graft can influence the outcome of the procedure in terms of risk of restenosis and subsequent graft failure. In this paper, we perform a computational fluid-structure interaction (FSI) analysis of patient-specific multiple CABGs (Y-grafts) with the aim of better understanding the influence of the choice of bypass (arterial vs venous) on the risk of graft failure...

OBJECTIVE: In this 8 years' follow-up study, we evaluated the long-term outcomes of the addition of clopidogrel to aspirin during the first year after coronary artery bypass grafting, versus aspirin plus placebo, with respect to survival, major adverse cardiac, or major cerebrovascular events, including revascularization, functional status, graft patency, and native coronary artery disease progression. METHODS: In the initial Clopidogrel After Surgery for Coronary Artery Disease trial, 113 patients were randomized to receive either daily clopidogrel (n = 56) or placebo (n = 57), in addition to aspirin, in a double-blind fashion for 1 year after coronary artery bypass grafting...

AIM: Diabetic kidney disease is one of the leading complications of Type 1 diabetes, but its prediction remains a challenge. We examined predictors of rapid decline in estimated GFR (eGFR) in two Type 1 diabetes cohorts: the Coronary Artery Calcification in Type 1 Diabetes (CACTI) and the Pittsburgh Epidemiology of Diabetes Complications (EDC). METHODS: A select subset of participants (CACTI: n = 210 and EDC: n = 98) diagnosed before 17 years of age with Type 1 diabetes duration ≥ 7 years, and follow-up data on eGFR by CKD-EPI creatinine for up to 8 years were included in the analyses...

BACKGROUND: Ischemic stroke and coronary heart disease are important contributors to the global disease burden and share atherosclerosis as the main underlying cause. Recent evidence from a genome-wide association study (GWAS) suggested that single nucleotide polymorphisms (SNP) near the MMP12 gene at chromosome 11q22.3 were associated with large-vessel ischemic stroke. Here we evaluated and extended these results by examining the relationship between MMP12 and atherosclerosis in clinical and experimental studies...

Frank's sign, also known as diagonal earlobe crease (DELC), was observed to be an aural sign of coronary artery disease (CAD). Since then, there has been much interest in examining this unique and controversial association. This report describes a patient who has bilateral complete and deep diagonal ear lobe creases, presented with angina and diagnosed to have coronary artery disease on angiography. The characteristics of the sign and its association with atherosclerotic disease were discussed.

Compared with age-matched men, premenopausal women are largely protected from coronary artery disease, a difference that is lost after menopause. The effects of oestrogens are mediated by the activation of nuclear receptors (ERα and ERβ) and by the G protein-coupled oestrogen receptor (GPER). This study aims to evaluate the potential role of GPER in coronary circulation in female and male rats. The baseline coronary perfusion pressure (CPP) and the concentration-response curve with a GPER agonist (G-1) were evaluated in isolated hearts before and after the blockade of GPER...

Kawasaki disease is an acute self-limiting systemic vasculitis. It is the most common cause of acquired heart disease, with the risk of developing coronary artery aneurysms, myocardial infarction and sudden death. Diagnosis is based on the presence of fever in addition to other clinical criteria. The quarter of the Kawasaki disease patients have "incomplete" presentation. Treatment with intravenous immunoglobulin within ten days of fever onset improves clinical outcomes and reduces the incidence of coronary artery dilation to less than 5%...

The independent predictive value of an unhealthy diet on the severity of coronary artery disease (CAD) requires further investigation. We assessed the impact of dietary pattern on CAD severity. In this cohort study, we included 188 symptomatic stable patients with CAD. Patients were categorized as having severe CAD or nonsevere CAD by coronary angiography. Among several demographics and clinical characteristics, all patients were tested using a semiquantitative food frequency questionnaire. Concerning baseline demographic characteristics, there was no difference between patients with severe CAD and nonsevere CAD...

Detecting coronary artery disease at a subclinical level has always been a challenging task for cardiologists. Various non-invasive echocardiographic approaches such as measurements of left ventricular hypertrophy, diastolic function, left atrial enlargement, valve sclerosis and calcification, epicardial fat thickness, and pulse wave velocity have been proposed to integrate the available risk-charts. The present review is a collection of evidence that supports the role of the above mentioned features in cardiac risk stratification, summarizing the state of the art in non-invasive echocardiographic coronary risk assessment...

BACKGROUND: Obstructive sleep apnea (OSA) is an independent risk factor for many cardiovascular conditions such as coronary artery disease, myocardial infarction, systemic hypertension, pulmonary hypertension, and stroke. However, the association of OSA with outcomes in patients hospitalized for ST-elevation myocardial infarction remains controversial. METHODS AND RESULTS: We used the nation-wide inpatient sample between 2003 and 2011 to identify patients with a primary discharge diagnosis of ST-elevation myocardial infarction and then used the International Classification of Diseases, Clinical Modification code 327...
