Results The baseline www.selleckchem.com/products/jq1.html characteristics of the 393 subjects are delineated in Table 1. The duration of known risk factors was not captured at baseline only their selleck Volasertib presence. There was only a single African-American subject in the data set. Ninety-two (23%) subjects were taking lipid-lowering therapy at baseline. The baseline characteristics of those not taking lipid lowering at baseline are shown in Table 2. Maximum wall thickness and CIMTAR values were Inhibitors,research,lifescience,medical similar in the overall group and the statin

naïve population (1.38, 1.32 mm; 0.026, 0.025 mm/year, respectively). A comparison of baseline characteristics, maximum wall thickness, and CIMTAR in several recent randomized clinical trials (O’Leary et al. 1999; Crouse et al. 2007; Kastelain et al. 2008) and our results is shown in Table 3. The results of dividing our study population into above and below median CIMTAR values are shown in the second and third columns of Tables 1 and ​and2.2. For the overall population, male gender and systolic blood pressure are the only baseline characteristics

Inhibitors,research,lifescience,medical that are statistically associated with elevated Inhibitors,research,lifescience,medical CIMTAR among traditional risk factors (P = 0.02, 0.002, respectively). Among those not taking lipid-lowering therapy, only systolic blood pressure remains significant (P = 0.0002). There was a statistically significant association between maximum wall thickness and baseline LDL for the entire population (P = 0.002), but the association is a negative one with a weak correlation (r = −0.17; Fig. 2). The association was not significant for the subjects not on lipid-lowering therapy (P = 0.07, r = −0.12). Scatter Inhibitors,research,lifescience,medical plots of CIMTAR and baseline LDL for the entire population were only weakly associated (P = 0.03, r = −0.12; Fig. 3). Again, the association was not significant for subjects not on lipid-lowering therapy

Such a single measure might also select subjects at risk prior to the development of risk factors.
