Prevention

Because there are no symptoms with high blood pressure, people can have the condition without knowing it. Diagnosing high blood pressure early can help prevent heart disease, stroke, eye problems, and chronic kidney disease. The risk of cardiovascular disease and death can be reduced by lifestyle modifications, including dietary advice, promotion of weight loss and regular aerobic exercise, moderation of alcohol intake and cessation of smoking. Drug treatment may also be needed to control the hypertension and reduce the risk of cardiovascular disease, manage the heart failure, or control cardiac arrhythmias. Patients with hypertensive heart disease should avoid taking over the counter

Blood pressure goals

According to JNC 7, BP goals should be as follows: * Less than 140/90mm Hg in patients with uncomplicated hypertension * Less than 130/85mm Hg in patients with diabetes and those with renal disease with less than 1g/24-hour proteinuria * Less than 125/75mm Hg in patients with renal disease and more than 1 g/24-hour proteinuria

. Hypertension increases the risk of heart failure by two or three-fold and probably accounts for about 25% of all cases of heart failure. In addition, hypertension precedes heart failure in 90% of cases, and the majority of heart failure in the elderly may be attributable to hypertension. Hypertensive heart disease was estimated to be responsible for 1.0 million deaths worldwide in 2004 (or approximately 1.7% of all deaths globally), and was ranked 13th in the leading global causes of death for all ages. A world map shows the estimated disability-adjusted life years per 100,000 inhabitants lost due to hypertensive heart disease in 2004.

Sex differences

There are more women than men with hypertension, and, although men develop hypertension earlier in life, hypertension in women is less well controlled. The consequences of high blood pressure in women are a major public health problem and hypertension is a more important contributory factor in heart attacks in women than men. Until recently women have been under-represented in clinical trials in hypertension and heart failure. Nevertheless, there is some evidence that the effectiveness of antihypertensive drugs differs between men and women and that treatment for heart failure may be less effective in women.

Ethnic differences

Studies in the US indicate that a disproportionate number of African Americans have hypertension compared with non-Hispanic whites and Mexican Americans, and that they have a greater burden of hypertensive heart disease. Heart failure is more common in people of African American ethnicity, mortality from heart failure is also consistently higher than in white patients, and it develops at an earlier age. Recent data suggests that rates of hypertension are increasing more rapidly in African Americans than other ethnic groups. The excess of high blood pressure and its consequences in African Americans is likely to contribute to their shorter life expectancy compared with white Americans.
