Impact of World Hypertension Day.

It is estimated that nearly one billion people are affected by hypertension worldwide, and this figure is predicted to increase to 1.5 billion by 2025. Nearly one-half of this population are unaware of their condition. Hypertension is the primary risk factor for heart disease and stroke. World Hypertension Day (WHD) has been an initiative of the World Hypertension League to raise hypertension awareness. In the past two years, many countries have taken an active part in promoting awareness through a number of initiatives in their respective countries. In Canada, WHD was a resounding success in 2005 and 2006, and major plans are underway for WHD 2007. The success of the Canadian WHD depends mainly on the partnership and shared values of all stakeholders, including professional societies, nongovernment organizations, government agencies and industry. Although it is too early to assess the impact of hypertension, it is evident that the countries involved are taking hypertension in the population seriously and are moving in the right direction. If the momentum continues, a drastic reduction in the prevalence of worldwide hypertension can be anticipated.
