Few studies have investigated the presence of dyslipidaemia in hypertensive individuals. In addition, few data exist on the concurrent treatment of both conditions for the prevention of cardiovascular disease (CVD). This retrospective cohort study examined treatment patterns for hypertension and dyslipidaemia among hypertensive patients in UK primary care. We defined a population of patients aged X40 years from the UK General Practice Research Database. Hypertensive individuals with X3 additional cardiovascular risk factors (ARFs) were compared with a cohort comprising hypertensive patients with p2 ARFs. We analysed the prevalence of risk factors and the prevalence and incidence of treatment for hypertension, dyslipidaemia and for both conditions between January 1997 and December 2001. A total of 117 840 hypertensive patients were identified (23 655 with X3 ARFs, 94 185 with p2 ARFs) in 1997; in 2001, the number diagnosed as hypertensive was 133 683 (40 248 X3 ARFs, 93 435 p2 ARFs). The prevalence of antihypertensive treatment in the hypertensive patients with X3 ARFs increased during the study. In 2001, approximately one-third of hypertensive patients with X3 ARFs were not receiving antihypertensives. Among those patients who received such treatment, the majority received X2 separate agents in accordance with current guidelines. Treatment for concurrent hypertension and dyslipidaemia was initiated in o8% of patients with hypertension and X3 ARFs in each year. These findings demonstrate the under-recognition/undertreatment of cardiovascular risk factors in UK primary care among patients at risk of CVD.
