Background:
Improving cardiovascular risk prediction continues to be a major challenge and effective prevention of cardiovascular disease. Accordingly, several studies have recently reported on the role of cardiovascular risk education. This study was designed to evaluate the impact of education on global cardiovascular risk in hypertensive patients.
Subjects And Methods:
The study population consisted of 223 consecutive hypertensive outpatients. Their educational status was categorized according to the number of years of formal education as follows: (1) low education (less than 10 years) and (2) medium-high education (10-15 years).
Results:
In both groups, cardiometabolic comorbidities, global cardiovascular risk and echocardiographic measurements were analysed. Less educated hypertensive subjects were characterized by a significantly higher prevalence of patients with metabolic syndrome (MetS) (p < .01), greater global cardiovascular risk (p < .001), and a higher consumption of antihypertensive drugs (p < .01) rather than medium-high educated hypertensive subjects. In the same subjects, a significant increase in microalbuminuria (MA) (p < .01) and a significant decrease in E/A (p < .001) ratio was found. Univariate analysis indicated that global cardiovascular risk correlated directly with waist-hip ratio, mean blood pressure, MA, left ventricular mass index, MetS and inversely with education (r = -0.45; p < .001). Education was independently (p < .001) associated with global CV risk.
Conclusions:
Our data suggest that education may be considered the best predictor of global cardiovascular risk in hypertensives and thus has to be evaluated in the strategies of hypertension and cardiovascular risk management.
