BACKGROUND: Lifestyle, environmental, and genetic factors substantially influence cardiovascular disease (CVD) risk. We aimed to explore epidemiologic trends in coronary artery calcium scores (CACS), as a marker of CVD, along with possible differences by geographic area and study period in separate East Asian populations. METHODS: We generated 3 matched groups (n=702) using a propensity scoring approach derived from a Korean (N=48,901) and Chinese cohort (N=927) as follows: (1) A recent Chinese group and (2) recent Korean group, both of whom underwent CACS scanning from 2012-2014; and (3) a past Korean group who underwent CACS scanning 8-10years before the index group (2002-2006)...

BACKGROUND AND AIMS: TAC is associated with incident CVD and all-cause mortality. Nevertheless, the independent 10-year prognostic value of TAC in individuals with CAC = 0 beyond traditional risk factors is not well established. METHODS: 3415 MESA participants with baseline CAC = 0 were followed for CHD, CVD events and all-cause mortality. TAC was measured in the ascending and descending aorta in all participants and quantified using Agatston's score. Multivariable Cox proportional hazards regression models were used to study the associations between TAC and incident CHD, CVD events and all-cause mortality...

During percutaneous coronary intervention, stents are placed in narrowings of the arteries to restore normal blood flow. Despite improvements in stent design, deployment techniques and drug-eluting coatings, restenosis and stent thrombosis remain a significant problem. Population stent design based on statistical shape analysis may improve clinical outcomes. Computed tomographic (CT) coronary angiography scans from 211 patients with a zero calcium score, no stenoses and no intermediate artery, were used to create statistical shape models of 446 major coronary artery bifurcations (left main, first diagonal and obtuse marginal and right coronary crux)...

Hyperparathyroidism may be associated with skeletal and cardiovascular abnormalities, but it is unclear whether these associations exist for high-normal levels of parathyroid hormone (PTH). We assessed relationships between PTH and anthropometric, skeletal and cardiometabolic indices in normal men. Body composition, blood pressure, biochemistry and bone mineral density (BMD) were evaluated in 151 healthy men. BMD was reassessed at 2 years, and coronary artery calcium (CAC) was measured at 3.5 years. Relationships between PTH and other baseline characteristics, CAC scores and change in BMD were evaluated...

INTRODUCTION: Chronic kidney disease-mineral bone disorder enhances coronary artery impairment (often occult and difficult to diagnose) in hemodialysis (HD) patients. The aim of the study was to correlate biochemical and imagistic parameters of MBD with the degree of documented coronary artery disease (CAD) in non-diabetic HD patients, in order to obtain a MBD-coronary risk score as a screening algorithm. METHODS: A 3-year prospective study was conducted on 168 non-diabetic HD patients, evaluating MBD biochemical parameters along with pulse wave velocity (PWV) determination and valve/coronary calcification assessment; coronary angiography was performed in symptomatic patients...

BACKGROUND: ABO blood groups have been confirmed to be associated with cardiovascular diseases such as coronary artery disease. However, whether ABO blood group is correlated with coronary artery calcium (CAC) is still unknown. METHOD: 301 patients with coronary artery calcium score (CACS) assessed by computed tomography were consecutively enrolled and divided into two groups: with calcium group (CACS>0, n=104) and without calcium group (CACS=0, n=197). Distribution of ABO blood groups was evaluated between the two groups...
