It is reasonable to suggest that most of these pathophysiologic effects of angiotensin II (through the stimulation of AT1 receptors) will result in pivotal, and potentially deleterious effects throughout the cardiovascular continuum. * Epidemiologic data has established for some time that hypertensive patients are at an increased risk for developing CHD compared to their normotensive counterparts. Specifically, data from Framingham as well as others have shown that patients with BPs 140/90 mm Hg are 2-4x more likely to develop cardiovascular disease than patients with BPs 140/90 mm Hg. Additionally, data has shown that reductions in BP through intervention can significantly decrease the risk of a cardiovascular event in the hypertensive patient. * * NVP0000901 CADUET? Global Speaker Slide Kit Version 2 There is a clear association between BP reduction and the risk of CV events. The CV protective effect of antihypertensive therapy was demonstrated by the findings of a meta-analysis of 29 trials in over 160,000 patients that compared different treatments or a treatment vs. placebo. The findings showed a clear association between a reduction in BP and in the relative risk of stroke, major CV disease, coronary heart disease, CV disease death and total mortality; the larger reductions in BP produced larger reductions in risk.
