Abstract

When managing hypertension, the assessment of the absolute risk of a cardiovascular' event is now advocated as the most accurate way in which the risks and benefits of anti-hypertensive therapy should be judged. Most studies that have examined control of hypertension have relied solely on the blood pressure level attained after treatment, with no measurement of the likely absolute risk in individual patients. To assess control of hypertension by quantifying the 10-year absolute risk of cardiovascular disease in patients treated by their general practitioners, and to assess which risk factors are associated with uncontrolled hypertension in this group of patients. A cross-sectional study was made of patients on drug treatment for hypertension in 18 Oxfordshire general practices subscribing to the VAMP (value-added medical products) computer system. The absolute risk of suffering a cardiovascular event in the following 10 years was measured according to each individual's risk factor profile. Factors associated with uncontrolled hypertension were ascertained using multiple logistic regression analysis. Overall, 40.9% (37.6% to 44.1%) of the hypertensive population had an absolute risk exceeding 20% of having a cardiovascular event...Continue Reading

Cardiovascular Disease Pathophysiology

Cardiovascular disease involves several different processes that contribute to the pathological mechanism, including hyperglycemia, inflammation, atherosclerosis, hypertension and more. Vasculature stability plays a critical role in the development of the disease. Discover the latest research on cardiovascular disease pathophysiology here.
