Background: Distribution of coronary artery calcium (CAC) has been determined in different heterogeneous populations in the Multi-Ethnic Study of Atherosclerosis (MESA). Based on findings showing that geography and culture can influence CAC scoring beyond traditional race groups, we determined the distribution of CAC in a homogenous black African population to provide an initial basis for a larger CAC score study in Africa. Methods and results: This is a preliminary study using computed tomography to determine the CAC scores within a black African population who were referred to our center...

BACKGROUND: The lifetime risk of coronary artery disease (CAD) is doubled in people with a family history of premature disease, yet this risk is not captured in most 5- or 10-year risk assessment algorithms. Coronary artery calcium scoring (CCS) is a marker of subclinical CAD risk, which has been shown in observational studies to provide prognostic information that is incremental to clinical assessment; is relatively inexpensive; and is performed with a small radiation dose. However, the use of CCS in guiding prevention is not strongly supported by guidelines...

BACKGROUND: Calcifications within the hippocampus were recently described for the first time on computed tomography (CT). These calcifications appeared in patients older than 50 years, the prevalence increases with age and they may be associated with cognitive decline. The aim of this study was to determine the histological basis (the presence, severity and location) of these CT-detected hippocampal calcifications of post-mortem brains. METHODS: CT scans of seven post-mortem brains were scored for the presence and severity (mild, moderate, severe) of hippocampal calcification...

BACKGROUND: Aortic valve calcification patterns were associated with short- and long-term outcomes in previous small observational datasets of patients undergoing transcatheter aortic valve implantation (TAVI). The specific impact of multi detector-row computed tomography (MDCT) findings on outcomes in women has not been reported. We sought to describe the associations between MDCT characteristics and clinical outcomes in a registry of 547 women undergoing TAVI. METHODS: WIN-TAVI is the first all-female registry to study the safety and effectiveness of TAVI in women (n = 1019)...

BACKGROUND: In view of the high mortality for cardiovascular diseases, it has become necessary to stratify the main risk factors and to choose the correct diagnostic modality. Studies have demonstrated that a zero calcium score (CS) is characteristic of a low risk for cardiovascular events. However, the prevalence of individuals with coronary atherosclerotic plaques and zero CS is conflicting in the specialized literature. OBJECTIVE: To evaluate the frequency of patients with coronary atherosclerotic plaques, their degree of obstruction and associated factors in patients with zero CS and indication for coronary computed tomography angiography (CCTA)...

Purpose: Anastomotic leakage is a major surgical complication following esophagectomy and gastric pull-up. Specific risk factors such as celiac trunk (TC) stenosis and high calcification score of the aorta have been identified, but no data are available on their relative prognostic values. This retrospective study aimed to compare and evaluate calcification score versus stenosis quantification with regards to prognostic impact on anastomotic leakage. Patients and methods: Preoperative contrast-enhanced computed tomography scans of 164 consecutive patients with primary esophageal cancer were evaluated by two radiologists to apply a calcification score (0-3 scale) assessing the aorta, the celiac axis and the right and left postceliac arteries...

Calcium score (CS) is a well-known prognostic factor after transcatheter aortic valve implantation (TAVI) performed with first generation prosthesis but few data are available concerning new generation valves. The aim of this study was to evaluate if CS remains a prognostic factor after Sapien 3 and Evolut R valves implantation. Agatston CS was evaluated on multislice computed tomography before TAVI in 346 patients implanted with Sapien XT (n = 61), CoreValve (n = 57) devices, (group 1, n = 118), and with new generation Sapien 3 (n = 147), Evolut R (n = 81) prosthesis, (group 2, n = 228)...

Osteoporosis and atherosclerosis are two prevalent major healthcare concerns that frequently coexist. The clinical outcome of 5590 consecutive subjects who underwent coronary artery calcium (CAC) scanning and thoracic bone mineral density (BMD) measurement was assessed. A significant link between low BMD levels and CAC with increased risk of mortality in both genders across ethnicities noted. INTRODUCTION: While a relation of CAC with lower levels of BMD reported previously; it is unclear whether low levels of BMD would be an independent risk factor for CAC and mortality...

BACKGROUND AND AIMS: Total coronary artery calcium (CAC) burden is associated with an increased cardiovascular risk, while local CAC may represent stable plaques. We determined differences in relationship of total CAC with acute coronary syndrome (ACS) and local CAC with culprit lesions in patients with suspected ACS. METHODS: We performed computed tomography (CT) for CAC and CT angiography to assess the presence of significant stenosis and high-risk plaque (positive remodeling, low CT attenuation, napkin-ring sign, spotty calcium) in 37 patients with ACS and 223 controls...

Background: The association between fibroblast growth factor 23 (FGF23) and coronary artery calcification (CAC) was inconclusive. Recently it was shown that adiponectin modulates renal handling of calcium and phosphorus. We hypothesized that adiponectin plays a role in the effect of FGF23 on CAC and explored whether the association between FGF23 and CAC is modified by serum adiponectin level in chronic kidney disease (CKD) patients. Methods: This cross-sectional study analyzed 1435 predialysis CKD patients from the Korean Cohort Study for Outcome in Patients with CKD cohort...

OBJECTIVES: Diagnostic accuracy of conventional coronary CT angiography (CCTAconv ) may be compromised by blooming artifacts from calcifications or stents. Blooming artifacts may be reduced by subtraction coronary CT angiography (CCTAsub ) in which non-contrast and contrast CT data sets are subtracted digitally. We tested whether CCTAsub in patients with severe coronary calcification or stents reduces the number of false-positive stenosis evaluations compared with CCTAconv . METHODS: In this study, 180 symptomatic patients scheduled for invasive coronary angiography (ICA) were prospectively enrolled and CT scanned (2013-2016) at three international centers...

AIMS: Coronary artery calcium (CAC) is associated with cardiovascular (CV) disease and progression of CAC is an independent predictor of mortality. Type 1 diabetes is associated with increased CV risk, especially in persons with cardiovascular autonomic neuropathy (CAN). This study aimed to examine whether short-term progression of CAC is increased in persons with type 1 diabetes compared to matched controls and if CAN increases risk of CAC progression. METHODS: Fifty-three normoalbuminuric persons with long-term type 1 diabetes (20 with CAN) were matched in a 1:2 ratio with 106 controls without diabetes according to age, sex and baseline CAC...

BACKGROUND AND AIMS: Left-sided valvular calcification is associated with cardiovascular disease (CVD) morbidity and mortality. Resting heart rate (RHR) may influence valvular calcium progression through shear stress. Whether RHR, an established CVD risk factor, is associated with valvular calcium progression is unknown. We assessed whether RHR predicts incidence and progression of mitral annular calcium (MAC) and aortic valve calcium (AVC) in a community-based cohort free of CVD at baseline...
