| Outcome Measures: |
Primary: Hypertension (24h Blood Pressure, Central Blood Pressure, and Office BP), 24-hour blood pressure collected by ambulatory automated arm cuff, central mean arterial blood pressure (MAP) collected by non-invasive arterial tonometry and pulse wave analysis/pulse wave velocity, office blood pressure collected by manual aneroid sphygmomanometry., 0, 2, and 4 months | Secondary: Brachial Artery Reactivity Testing, Brachial artery response to hyperemia assessed by measuring brachial artery diameter every 30 seconds for 180 seconds after a 5-minute occlusion with arm cuff above systolic blood pressure, with response defined as maximal percentage increase above baseline., 0, 2, and 4 months|Macrophage Cholesterol Metabolism, Macrophage uptake of labeled oxidized low density lipoprotein, assessed by the ratio of post-treatment cholesterol uptake to baseline uptake., 0 and 4 months|Serum Calcium, Serum calcium assessed by photometric assessment after calcium reaction with NM-BAPTA, then with EDTA, 0, 2, and 4 Month|HbA1C, HbA1c percentage assessed by turbidimetric inhibition immunoassay for hemolyzed whole blood, 0, 2, and 4 month|Vitamin D, 25(OH) Vitamin D assess by liquid chromatography with tandem mass spectrometry, 0, 2, and 4 Month|hsCRP, High sensitivity C-reactive protein assessed by particle-enhanced immunoturbidimetric assay, 0, 2, and 4 Month|Fasting Glucose, Serum fasting glucose assessed by hexokinase method, 0, 2, and 4 Month|Urine Calcium to Creatinine Ratio., Urine calcium to creatinine ratio assessed by spectrophotometry, 0, 2 and 4 Months
