Background: Failure of delivering a stent or a balloon across the target lesion during percutaneous coronary intervention (PCI) of chronic total occlusion (CTO), especially in arteries with calcified tortuous anatomy, is often due to insufficient backup support from the guiding catheter. The purpose of this study was to assess the feasibility of the GuideLiner (GL) catheter use. Methods: We examined 18 patients and used the GL catheter to overcome poor support and excessive friction in standardized antegrade and retrograde CTO procedures...

BACKGROUND: Raised hemoglobinA1c (HbA1c) is an indicator of pre-diabetes, which is associated with increased risk of coronary artery disease. However, the detailed morphological characteristics of non-culprit plaques in acute coronary syndrome (ACS) patients remain largely unknown. METHODS: A total of 305 non-culprit plaques from 216 ACS patients were analyzed by intravascular optical coherence tomography. These patients were divided into three groups according to the serum glycosylated hemoglobin level: normal HbA1c (< 5...

BACKGROUND: COPD is associated with cardiovascular disease (CVD), and coronary artery calcification (CAC) provides additional prognostic information. With increasing use of non-gated CT scans in clinical practice, we hypothesized that the visual Weston CAC score would perform as well as Agatston score in predicting prevalent and incident coronary artery (CAD) and CVD in COPD. METHODS: We measured CAC using Agatston and Weston scores on baseline CT scans in 1875 current and former smokers enrolled in the COPDGene study...

Familial hypercholesterolemia (FH) is a genetic disease associated with persistently elevated levels of low-density lipoprotein cholesterol (LDL-C), which ultimately leads to greatly increased rates of atherosclerosis and cardiovascular disease. Atherosclerosis progression can be clinically approximated through measurement of coronary artery calcification (CAC). CAC can be measured via electron beam computed tomography (EBCT), multi-slice computed tomography (MSCT), or contrast-enhanced CT coronary angiography (CTCA)...

We hypothesized that severity of coronary artery calcification (CAC), emphysema, muscle mass, and fat attenuation can help predict mortality in patients with lung cancer participating in the National Lung Screening Trial (NLST). Following regulatory approval from the Cancer Data Access System (CDAS), all patients diagnosed with lung cancer at the time of the screening study were identified. These subjects were classified into two groups: survivors and nonsurvivors at the conclusion of the NLST trial. These groups were matched based on their age, gender, body mass index (BMI), smoking history, lung cancer stage, and survival time...

Coronary artery calcification(CAC) is reflective of atherosclerotic disease and incrementally predictive of future cardiovascular events, independent of traditional risk factors. Extra coronary calcium such as aortic valve calcification, which can be identified and quantified by Computed Tomography(CT) imaging, has shown to predict future cardiovascular events in both asymptomatic and symptomatic (ie - stable angina and acute coronary syndrome) settings. It has hence been a vital tool in studies involving new therapies for cardiovascular disease...

BACKGROUND: The mechanisms by which exercise reduces the risk of coronary heart disease remain poorly understood. Irisin, an exercise-induced polypeptide secreted from skeletal muscles, is proposed to potentially mediate beneficial effects of exercise, especially in metabolic regulation and development of atherosclerosis. We examined whether higher serum irisin levels are associated with lower prevalence and progression of coronary atherosclerosis. METHODS AND RESULTS: We performed a prospective, population-based study of Japanese men aged 40-79 years without known coronary heart disease...

BACKGROUND AND AIMS: The association between minimally elevated coronary artery calcification (CAC) and cerebrovascular disease is not well known. We assessed whether individuals with minimal CAC (Agatston scores of 1-10) have higher ischemic stroke or transient ischemic attack (TIA) frequencies compared with those with no CAC. We also investigated the relative prevalence of carotid atherosclerosis in these two groups. METHODS: A total of 3924 participants from the Multi-Ethnic Study of Atherosclerosis (MESA) without previous cardiovascular events, including stroke, and with baseline CAC scores of 0-10 were followed for the occurrence of incident ischemic stroke/TIA...

OBJECTIVES: The aim of this study was to determine the clinical outcomes of patients with long, diffusely calcified coronary artery lesions who underwent orbital atherectomy. BACKGROUND: The presence of severe coronary artery calcification increases the complexity of percutaneous coronary intervention. Orbital atherectomy of long, diffusely calcified lesions may increase the risk of periprocedural angiographic complications. Furthermore, the rate of ischemic complications, including target-vessel revascularization (TVR), in these long, calcified lesions is historically high...

REVIEW
Kamonwan Tangvoraphonkchai, Andrew Davenport
Magnesium is the most abundant intracellular divalent cation and essential for maintaining normal cellular physiology and metabolism, acting as a cofactor of numerous enzymes, regulating ion channels and energy generation. In the heart, magnesium plays a key role in modulating neuronal excitation, intracardiac conduction, and myocardial contraction by regulating a number of ion transporters, including potassium and calcium channels. Magnesium also has a role in regulating vascular tone, atherogenesis and thrombosis, vascular calcification, and proliferation and migration of endothelial and vascular smooth muscle cells...
