Global burden of high blood pressure in 2001• Worldwide 54 % of stroke and 47 % of

ischemic heart disease were attributable to high blood pressure

• Half of this burden occurred in people with hypertension, the remainder in those with lesser degree of high BP

• About 80 % of attributable burden occurred in low and middle-income countries, over half in people aged 45-69 years old

The advantage of benazepril/amlodipine vs. benazepril/hctz was driven by non-fatal MI and coronary revascularization
