background: an electrocardiogram (ecg) can provide information on subclinical myocardial damage. the presence, and more importantly, the quantity of coronary artery calcification (cac), relates well with the overall severity of the atherosclerotic process. a strong relation has been demonstrated between coronary calcium burden and the incidence of myocardial infarction, a relation independent o...

objectives to evaluate predictive value of vessel specific coronary artery calcium (cac) score in predicting obstructive coronary artery disease. patients and methods in this diagnostic test study we evaluated patients with coronary computed tomography angiography (ccta) and cac score which had been referred to two referral radiology center in tehran, iran and finally we selected 2525 patients ...

This paper focuses on a new Wireless LAN developed in the framework of the WIND-FLEX project, sponsored by the European IST program. Medium Access Control and Dynamic Link Control protocols are described with respect to their functionalities and the implemented algorithms. The main emphasis is on the Connection Admission Control algorithm, which is devoted to guarantee the preventive control of...

A $p$-group $G$ is called a $mathcal{CAC}$-$p$-group if $C_G(H)/H$ is ‎cyclic for every non-cyclic abelian subgroup $H$ in $G$ with $Hnleq‎ ‎Z(G)$‎. ‎In this paper‎, ‎we give a complete classification of‎ ‎finite $mathcal{CAC}$-$p$-groups‎.

BACKGROUND Cardiovascular disease is the leading cause of mortality among renal transplant recipients. In the general population, coronary artery calcification (CAC) and progression of CAC are predictors of future cardiac risk. We conducted a study to determine the progression of CAC in renal transplant recipients; we also examined the factors associated with progression and the impact of the a...

AIMS We sought to quantify coronary artery calcium (CAC) using a single contrast-enhanced cardiac computed tomography angiography (CCTA) study. CCTA has been successfully used for the assessment of coronary artery stenoses, whereas non-contrast ECG-gated computed tomography (Standard-CAC) is commonly performed to quantify CAC. Thus each scan individually contributes to the total radiation dose....

OBJECTIVES We sought to quantify the mortality rates associated with absent and low positive (CAC 1 to 10) coronary artery calcium (CAC). BACKGROUND There is increasing interest in the absence of CAC as a "negative" cardiovascular risk factor. However, published event rates for individuals with no CAC vary, likely owing to differences in baseline risk, follow-up period, and outcome ascertainm...
