High BP may affect 1.56 bln people by 2025
Reported November 12, 2010
High blood pressure affects over one billion people globally and the number is expected to rise to 1.56 billion people by 2025.
It is a condition that often does not display signs or symptoms, hence it is commonly referred to as a ‘silent killer’. For this reason, many people are not aware that they have this condition until they visit a doctor.
Hypertension, or elevated blood pressure, indicates that the heart is working harder than normal, putting both the heart and the arteries under a greater strain.
The Malaysian Society of Hypertension classifies hypertension as a condition where the systolic pressure is greater than 140 mmHg or the diastolic pressure greater than 90 mmHg. Typically, three separate abnormally high readings over a few weeks is necessary to diagnosis this condition.
High blood pressure contributes to heart attacks, strokes, renal failure and atherosclerosis. If the condition is left untreated or unmanaged, the heart may have to work harder to pump enough blood and oxygen to the body’s organs and tissues to meet their needs.
In Malaysia, four out of 10 adults suffer from high blood pressure with only 26 per cent of the affected people having their blood pressure under control.
The direct and indirect costs of treating high blood pressure were estimated at USD 849.68 and USD 2,347.18 respectively per patient in 2009.
In addition, up to 85 per cent of patients may need multiple medications to help control their blood pressure, underscoring the need for more effective combination treatments. It is clearly a major public health problem.
