          Abstract

          Background: Evaluation of coronary artery disease (CAD) and aortic atherosclerosis has been performed in patients with acute ischemic stroke. We investigated the usefulness of a dual-source CT (DSCT) protocol enabling the comprehensive evaluation of CAD and aortic atherosclerosis. The clinical characteristics of those patients who would benefit more from this protocol were investigated based on vascular risk factors, Framingham Risk Score (FRS), and stroke subtype. Methods: Of 469 patients with acute ischemic stroke, the 274 who had no history of CAD and had undergone DSCT were analyzed. Predictors of CAD (≧50% stenosis) or complicated aortic plaque (CAP) were evaluated based on vascular risk factors, FRS and stroke subtype. Results: Of the 274 patients analyzed, asymptomatic CAD (≧50% stenosis) was found in 61 (22.3%) and CAP in 58 (21.2%). Furthermore, the severity of CAD or aortic atherosclerosis was correlated with FRS (CAD, r = 0.291, p < 0.001 and aortic atherosclerosis, r = 0.297, p < 0.001). Additionally, severe CAD and aortic atherosclerosis were independent predictors of each other: CAP for the presence of CAD (≧50% stenosis) [odds ratio (OR), 5.71; 95% confidence interval (CI), 1.94–16.87]; CAD (≧50% stenosis) for the presence of CAP (OR, 4.20; 95% CI, 1.82–9.72). Specific stroke subtypes as well as large-artery atherosclerosis (OR, 5.25; 95% CI, 2.24–12.31) and cardioembolism (OR, 5.22; 95% CI, 1.75–15.60) were associated with the presence of CAP. Conclusions: A comprehensive evaluation protocol for CAD and aortic atherosclerosis may be useful in acute ischemic stroke patients, especially in those with higher FRS or specific stroke subtypes.

          General cardiovascular risk profile for use in primary care: the Framingham Heart Study.

          Ralph B. D’Agostino, Ramachandran S. Vasan, Michael J. Pencina … (2008)
          Separate multivariable risk algorithms are commonly used to assess risk of specific atherosclerotic cardiovascular disease (CVD) events, ie, coronary heart disease, cerebrovascular disease, peripheral vascular disease, and heart failure. The present report presents a single multivariable risk function that predicts risk of developing all CVD and of its constituents. We used Cox proportional-hazards regression to evaluate the risk of developing a first CVD event in 8491 Framingham study participants (mean age, 49 years; 4522 women) who attended a routine examination between 30 and 74 years of age and were free of CVD. Sex-specific multivariable risk functions ("general CVD" algorithms) were derived that incorporated age, total and high-density lipoprotein cholesterol, systolic blood pressure, treatment for hypertension, smoking, and diabetes status. We assessed the performance of the general CVD algorithms for predicting individual CVD events (coronary heart disease, stroke, peripheral artery disease, or heart failure). Over 12 years of follow-up, 1174 participants (456 women) developed a first CVD event. All traditional risk factors evaluated predicted CVD risk (multivariable-adjusted P<0.0001). The general CVD algorithm demonstrated good discrimination (C statistic, 0.763 [men] and 0.793 [women]) and calibration. Simple adjustments to the general CVD risk algorithms allowed estimation of the risks of each CVD component. Two simple risk scores are presented, 1 based on all traditional risk factors and the other based on non-laboratory-based predictors. A sex-specific multivariable risk factor algorithm can be conveniently used to assess general CVD risk and risk of individual CVD events (coronary, cerebrovascular, and peripheral arterial disease and heart failure). The estimated absolute CVD event rates can be used to quantify risk and to guide preventive care.

            Ischemic stroke in cancer patients with and without conventional mechanisms: a multicenter study in Korea.

            Bong Kim, Melissa Hong, Kwang-Tae Park … (2010)
            To assess the precise mechanisms of stroke in cancer patients, we analyzed the data for cancer patients with acute ischemic stroke registered from 6 centers in South Korea. Clinical features, risk factors, diffusion-weighted imaging lesion patterns, and laboratory findings including D-dimer levels were compared between patients with conventional stroke mechanisms (CSMs) and cryptogenic group. A total of 161 patients were included in this study: 97 (60.2%) patients in the CSM group and 64 (39.8%) in the cryptogenic group. Patients in the CSM group were older and vascular risk factors were more prevalent than in the cryptogenic group. Diffusion-weighted imaging patterns of multiple lesions involving multiple arterial territories were observed more frequently in the cryptogenic group than in the CSM group. In addition, levels of the D-dimer were higher in the cryptogenic group than in the CSM group (11.5+/-14.6 versus 3.6+/-10.3 microg/dL). In multivariate analysis, the diffusion-weighted imaging lesion pattern of multiple vascular territories (odds ratio, 11.2; 95% CI, 3.74 to 33.3), and D-dimer levels of >1.11 microg/dL (odds ratio, 10.6; 95% CI, 3.29 to 33.8) were associated independently with the cryptogenic group. Stroke outside of CSM occurred in a large number in cancer patients. In stroke patients with cancer, d-dimer levels and diffusion-weighted imaging lesion patterns may be helpful in early identification of non-CSMs (especially coagulopathy associated with cancer) and possibly in guiding preventive strategies for stroke.

              Diagnostic performance of multidetector CT angiography for assessment of coronary artery disease: meta-analysis.

              Piet Vanhoenacker, Majanka Heijenbrok-Kal, Ruben Van Heste … (2007)
              To review the literature on the diagnostic performance of multidetector computed tomographic (CT) angiography for assessment of symptomatic coronary artery disease, with conventional coronary angiography as the reference standard. A PubMed and manual search of the literature published between January 1998 and May 2006 on use of multidetector CT angiography compared with coronary angiography in patients with symptomatic coronary artery disease was performed. Summary estimates of diagnostic odds ratio, sensitivity, and specificity were calculated. Random-effects models were used to compare the diagnostic performance of four-, 16-, and 64-detector CT angiographic units, and the proportion of nonassessable coronary arterial segments was evaluated. Fifty-four studies were included in the meta-analysis: 22 studies with four-detector CT angiography, 26 with 16-detector CT angiography, and six with 64-detector CT angiography. The pooled sensitivity and specificity for detecting a greater than 50% stenosis per segment were 0.93 (95% confidence interval [CI]: 0.88, 0.97) and 0.96 (95% CI: 0.96, 0.97) for 64-detector CT angiography, 0.83 (95% CI: 0.76, 0.90) and 0.96 (95% CI: 0.95, 0.97) for 16-detector CT angiography, and 0.84 (95% CI: 0.81, 0.88) and 0.93 (95% CI: 0.91, 0.95) for four-detector CT angiography, respectively. Results of regression analysis indicated that the diagnostic performance significantly improved with the newer generations of multidetector CT scanners (64- and 16-detector vs four-detector units), adjusted for exclusion of nonassessable segments, and contrast agent concentration used (P < .05). Simultaneously, the nonassessable proportion of segments significantly decreased with the newer generations of multidetector CT scanners, adjusted for heart rate, prevalence of significant disease, and mean age. With the newer generations of multidetector CT scanners, the diagnostic performance for the assessment of coronary artery disease has significantly improved, and the proportion of nonassessable segments has decreased.
