Detection of asymptomatic embolization on TCD can be used to identify patients with ACS who are at a higher risk http://www.selleckchem.com/products/Staurosporine.html of stroke and TIA. A number of prospective studies have examined associations between ultrasonic plaque characteristics and stroke risk in ACS. Associations

have been detected with a number of features including texture heterogeneity, echolucency, and surface irregularities [14]. A limited number of studies have used a simple measure of echolucency and these have shown conflicting results. More recently, data from ACES demonstrated that plaque morphology assessed using a simple visual rating scale predicts ipsilateral stroke in ACS [14]. 435 subjects with ACS ≥ 70% were included and followed-up for 2 years. A 4-point visual rating scale was applied to the plaques and they were classified as echolucent (37.7%) or echogenic. Plaque echolucency at baseline was associated with an increased risk of ipsilateral stroke alone (HR 6.43, 95% CI 1.36–30.44). A combination of plaque echolucency and ES positivity at baseline was associated with an increased risk of ipsilateral stroke alone (HR 10.61, 95% CI 2.98–37.82). The combination of ES

detection and plaque morphology allows a greater prediction than either measure alone and identifies a high-risk group with an annual stroke risk of 8%, and a low-risk group with a risk of <1% per year. These data show that the combination of 2 measures

of plaque instability may identify a high-risk group of patients with ACS that Trichostatin A mouse may benefit from a CEA. Plaque morphology assessed using a simple and clinically applicable, visual rating scale predicts ipsilateral stroke risk in ACS. Peripheral arterial disease (PAD) is increasingly recognized as a clinically important marker of atherosclerotic disease due to its association with cardiovascular Dynein disease incidence and mortality. Determination of the ABI, which is the ratio of systolic pressure at the ankle to that in the arm, is quick, easy to measure and a noninvasive method used to establish the presence of PAD. The equipment is inexpensive – a handheld Doppler sonograph costs less than 400 EUR. The procedure is simple, taking less than 10–15 min, and can be performed by a suitably trained nurse or health care professional. A reduced ABI has been shown to identify patients at risk for cardiovascular events (Table 1). Patients with stroke or transient ischemic attack often had PAD. However, it is still unclear whether PAD is also a good predictor for future cerebrovascular disease. A recent meta-analysis demonstrated a pooled multivariate adjusted relative risk of 1.35 (95% confidence interval, CI 1.10–1.65) for stroke in patients with an ABI < 0.9 [15]. Meves et al. [16] analyzed the association between PAD, either symptomatic or asymptomatic (defined as an ABI < 0.
