OBJECTIVES This study evaluated whether coronary artery calcium scores (CACS) and the degree of stenosis that were measured with computed tomography coronary angiography (CTCA) predicted post-operative cardiovascular events in patients who were undergoing intermediate-risk noncardiac surgery. BACKGROUND Cardiovascular complications are important causes of mortality and morbidity in patients u...

Coronary arterial calcium score (CACS) has been considered to be an important index to indicate the severity of coronary atherosclerosis noninvasively. However, even if CACS is 0, it is reported that the presence of coronary atherosclerosis is not always deniable. In a multicenter CORE64 (Coronary Artery Evaluation Using 64-Row Multidetector Computed Tomography Angiography) trial, among 24% of ...

BACKGROUND Recent studies have suggested that metabolic health may contribute more to the atherosclerosis than obesity. The aim of this study is to compare coronary artery calcium scores (CACS) among patients with different metabolic health and obesity status. METHODS A health-screening program of 24,063 participants (mean age 41 years) was conducted, and CACS was assessed by multi-detector c...

Coronary artery calcification (CAC) is associated with increased mortality in patients on maintenance hemodialysis (MHD), but the pathogenesis of this condition is not well understood. We evaluated the relationship of CAC score (CACs) and variability in serum phosphorus in MHD patients. Seventy-seven adults on MHD at Huashan Hospital (Shanghai) were enrolled in July, 2010. CAC of all the patien...

BACKGROUND It remained unclear whether the combination of the Canada Acute Coronary Syndrome Risk Score (CACS-RS) and N-terminal pro-brain natriuretic peptide (NT-pro-BNP) could have a better performance in predicting clinical outcomes in acute ST-elevation myocardial infarction (STEMI) patients with primary percutaneous coronary intervention. METHODS A total of 589 consecutive STEMI patients...

BACKGROUND Cell transplantation for regenerative medicine has become an appealing therapeutic method; however, stem and progenitor cells are not always freshly available. Cryopreservation offers a way to freeze cells as they are generated, for storage and transport until required for therapy. This study was performed to assess the feasibility of cryopreserving peripheral blood mononuclear cells...

Better model to predict arrhythmia recurrence post pulmonary vein isolation (PVI) for persistent atrial fibrillation (AF) is needed. Atrial epicardial adipose tissue (aEAT) and coronary arteriosclerosis has been reported associate with left substrate of AF. We aimed assess the influence aEAT artery calcium score (CACS) on outcome PVI evaluated consecutive 105 patients (age 62±10 years, 86 males...

BACKGROUND It is not clear how severe metabolic syndrome (MS) affects the development of coronary atherosclerosis. METHODS This was an observational, retrospective cohort study with Koreans who received health check-ups voluntarily. A total of 2426 subjects had baseline and follow-up coronary artery calcium score (CACS) data. Among them, 1079 had coronary computed tomography angiography (CCTA...

BACKGROUND AND OBJECTIVES Non-calcified plaque (NCP) identified by coronary CT angiography (CCTA) has been reported in up to 10% of individuals with coronary artery calcium score (CACS) of zero. However, clinical risk factors and the prognostic value of NCP in asymptomatic subjects with CACS of zero are unknown. SUBJECTS AND METHODS The study population consisted of consecutive asymptomatic s...

By applying the health protection method of “bu” and the treatment method “xie” from traditional Chinese medicine to ant colony system (ACS), a novel ant colony system (CACS) is proposed. The core of CACS lies in the construction of “bu” operator and “xie” operator. The “bu” operator is made up of the good solution elements pool and the “bu” operation. The “bu” operation is that ants select fro...
