Hypertension affects up to 50 million Americans, and is a major risk factor for cardiovascular disease and other health outcomes. Among Black women, hypertension is more prevalent, less well controlled by treatment, and has more damaging health outcomes versus Whites for reasons still unclear. While several lifestyle and dietary factors are associated with hypertension, relevant biochemical and genetic markers remain less well studied
This is a nested case-control study of incident hypertension in 800 case-control pairs (400 each of white and black women, totaling 1,600 women). Data will be used from the Women's Health Initiative Observational Study (WHI-OS), a cohort of 93,676 ethnically diverse postmenopausal women aged 50 to 79 years with extensive clinical and questionnaire data. Three hypotheses will be tested. First, the investigators will assess whether markers of inflammation - C reactive protein (CRP), interleukin-6 (IL-6), IL-1-8, tumor necrosis factor (TNF) receptor 2, soluble intercellular adhesion molecule-1 (slCAM-1), and metalloproteinase-9 (MMP-9) - are associated with the risk of hypertension in White and Black women. Second, they will examine six novel polymorphisms linked to the above inflammatory biomarkers - the CRP, IL-6, IL-1-beta, TNF-a, slCAM-1, and MMP-9 genes- and two other polymorphisms related to inflammation and the metabolic syndrome- the adiponectin and PPAR-y2 genes - for their potentially important associations with the risk of hypertension. Third, they will comprehensively evaluate important single-nucleotide polymorphisms in the above genes and examine associations between common haplotypes and hypertension risk in White and Black women, using state-of-the art genotyping technology and statistical methods. Power is excellent; for each biochemical marker, they have 80% power to detect a trend across quintiles for a relative risk (RR) of hypertension, comparing the fifth versus first quintiles, of 1.49 for analyses of 800 case-control pairs and 1.74 for analyses of 400 case-control pairs. For each genetic marker, they have 80% power to detect an additive effect of an allele for a RR of hypertension of 1.36 for 800 case-control pairs and 1.57 for 400 case-control pairs.

Unexpected rapid natural death due to cardiovascular collapse within one hour of initial symptoms. It is usually caused by the worsening of existing heart diseases. The sudden onset of symptoms, such as CHEST PAIN and CARDIAC ARRHYTHMIAS, particularly VENTRICULAR TACHYCARDIA, can lead to the loss of consciousness and cardiac arrest followed by biological death. (from Braunwald's Heart Disease: A Textbook of Cardiovascular Medicine, 7th ed., 2005)

Blood pressure levels that are between normotension and hypertension. Individuals with prehypertension are at a higher risk for developing cardiovascular diseases. Generally, prehypertension is defined as SYSTOLIC PRESSURE of 131-139 mm Hg and/or DIASTOLIC PRESSURE of 81-89 when the optimal is 120/80 mm Hg. For diabetics and other metabolism diseases the prehypertension is around 110-129/70-79 mm Hg.
