3.2. Comparison between patients with adequate and inadequate adherence
Bivariate analysis showed that patients with inadequate adherence were older (p= 0.010), a more extensive proportion lived in rural areas (p= 0.005), and had higher total cholesterol (p< 0.0001) and triglycerides levels (p= 0.003) compared with their adherent counterparts. Moreover, participants with a low educational level, including those with middle school or less as the highest level of education completed, showed inadequate adherence patterns to treatment contrasted with those with high school or a college degree ( p< 0.0001). Finally, patients on a combined pharmacological therapy with either PCI or CABG were more adherent than those on optimal medical therapy alone (p =0.004). Likewise, a higher proportion of patients in the inadequate group were in NYHA classes II and III (p< 0.0001), as shown in Table 2.
