Abstract 143: Pregnancy Dependant Transcriptomic Changes in Uterine Arteries From Hypertensive and Normotensive Rat Models Session Title: Developmental Programming and Pregnancy Induced Hypertension
This study investigated early gene expression changes in the uterine arteries (UA) of pregnant SHRSP and normotensive Wistar Kyoto (WKY) rats.Methods: SHRSP and WKY females were time mated and UA isolated at gestational day (GD)6 (n=3). Non-pregnant (NP) UA were isolated from virgin aged matched controls (n=3). UA RNAseq (Illumina platform) was performed. Transcript level gene changes were interpreted using Ingenuity Pathway Analysis (FDR 1.0). Quantitative RT-PCR was used to validate significantly differentially expressed genes.Results: There was a greater number of differentially expressed transcripts NP v GD6 in SHRSP c...

Abstract P480: Effects Of Long And Intermediate Acting Dihydropyridine Calcium Channel Blockers In Hypertension: A Systematic Review And Aeta-analysis Of 18 Prospective, Actively Controlled, Randomized Clinical Trials Session Title: Antihypertensive Drugs and Pharmacology, Patient-Provider-Healthcare System Issues, and Pediatric and Adolescent Hypertension
Conclusions: This study suggests that Amlodipine offers greater protection against major complications of hypertension compared to intermediate acting dihydropyridine calcium channel blockers.

Abstract 031: Diastolic Blood Pressure, Coronary Artery Calcium, and Cardiac Outcomes in the Multi-ethnic Study of Atherosclerosis Session Title: Cardiac Hypertrophy and Dysfunction
Diastolic blood pressure (BP) has a J-curve relationship with coronary heart disease and death. Because this association is thought to reflect reduced coronary perfusion at low diastolic BP, our objective was to test whether the J-curve is most pronounced among persons with coronary artery calcium. Among 6,811 participants from the Multi-Ethnic Study of Atherosclerosis, we used Cox models to examine if diastolic BP category is associated with coronary heart disease events, stroke, and mortality. Analyses were conducted in the sample overall and after stratification by coronary artery calcium score. In multivariable-adjuste...

Abstract 70: Eplerenone Increases Dilation and the Diameter of Cerebral Penetrating Arterioles in Rats with Sustained Hypertension Oral Session IX: Concurrent A Aldosterone, Its Receptors and Other Hormones
Hypertension is linked to dementia in humans, as well as remodeling and dysfunction in large cerebral arteries. The effects of hypertension on cerebral microvessels, such as penetrating arterioles (PenA), are still unknown. These arterioles are the bottlenecks bridging the pial circulation to the deep parenchymal microcirculation, and they are vital for neurovascular coupling and functional hyperemia. Mineralocorticoid receptor (MR) antagonism reverses hypertension-induced changes in large cerebral arteries. Thus, we hypothesized that MR antagonism will improve PenA dilation and structure in adult rats with sustained hyper...

Mortality and Morbidity During and After Antihypertensive and Lipid-Lowering Treatment to Prevent Heart Attack Trial: Results by Sex Clinical Trial - ALLHAT
To determine whether an angiotensin-converting enzyme inhibitor (lisinopril) or calcium channel blocker (amlodipine) is superior to a diuretic (chlorthalidone) in reducing cardiovascular disease incidence in sex subgroups, we carried out a prespecified subgroup analysis of 15 638 women and 17 719 men in the Antihypertensive and Lipid-Lowering Treatment to Prevent Heart Attack Trial (ALLHAT). Total follow-up (active treatment + passive surveillance using national administrative databases to ascertain deaths and hospitalizations) was 8 to 13 years. The primary outcome was fatal coronary heart disease or nonfatal myocardial i...

Left Ventricular Global Function Index by Magnetic Resonance Imaging--A Novel Marker for Assessment of Cardiac Performance for the Prediction of Cardiovascular Events: The Multi-Ethnic Study of Atherosclerosis Epidemiology/Population Science
Left ventricular (LV) function is generally assessed independent of structural remodeling and vice versa. The purpose of this study was to evaluate a novel LV global function index (LVGFI) that integrates LV structure with global function and to assess its predictive value for cardiovascular (CV) events throughout adult life in a multiethnic population of men and women without history of CV diseases at baseline. A total of 5004 participants in the Multi-Ethnic Study of Atherosclerosis underwent a cardiac magnetic resonance study and were followed up for a median of 7.2 years. The LVGFI by cardiac magnetic resonance was def...
