Explanation of how quick and simple it is to scan for the amount of calcium in your arteries; Description of why test results with high calcium scores are much more of a threat to young people than to the elderly; Observation that calcium scans are best at predicting heart problems in ...
RESULTS: The mean calcium score was 151 +/- 403 and the prevalence of obstructive CAD was 17% (8% one-vessel and 10% two-vessel disease). Per-patient sensitivity, specificity, positive and negative predictive values of CACS were: 97%, 75%, 45%, and 100%, respectively (Agatston >or=...
Relationship between age and calcium score was analysed with Spearma's Rank, regression analysis and receiver operating characteristics (ROC). Results 1665 patients were identified and 164 were excluded, leaving 1501 patients (F=735, M=766; Range=17-94; Median=58). The proportion of clinically ...
The coronary artery calcium score and stress myocardial perfusion imaging provide independent and complementary prediction of cardiac risk. This study sought to examine the relationship between coronary artery calcium score (CACS) and single-photon emission computed tomography (SPECT) results f... MC Su...
0.80. Results: In total 58% of patients had obstructive CAD of which seventy-four percent were male. Addition of CAC scores to MPI and clinical predictors significantly improved the diagnostic accuracy of MPI to detect obstructive CAD. The area under the curve (AUC) increased from 0.87 to ...
Our results indicated that calcium activity in the PL correlated positively with movement during stress exposure and negatively with freezing behavior during both FC and FE, with no sex differences found in the correlation levels. This suggests that the PL subregion of the PFC might have a ...
Results We included 761 patients of which 125 (16%) required PPM at 30 days. AVCS score was significantly higher in patients requiring PPM (3788 (2487–5218) vs 3050 (2043–4367) AU, p<0.001). Using multivariable analysis, preprocedural right bundle branch block (RBBB) (OR 6.61, 95% ...
16 Thus, we used DLR to compute the change from pretest (based on traditional cardiovascular risk factors alone) to posttest risk that was associated with the results of a subsequent test showing a negative risk marker (ie, a CAC score of 0 in this study). A DLR value greater than 1 ...
attenuation or respiratory artifact, justifying further CAD rule-out withCT angiography. However, despite encouraging results, the real role of the calcium score in the cascade of noninvasive investigations of CAD remains to be determined. View chapter...
