1 Caveolin-1 and Vascular Dysfunction

Caveolin-1 and Vascular Dysfunction Thank you for your interest in the investigators Blood Pressure Research Study. The National Institutes of Health are sponsoring us to investigate why patients develop high blood pressure, atherosclerosis (hardening of the arteries), and heart disease. There are two parts of the investigators research program. The first part is a screening visit. At this visit you will be given a brief physical exam and will be asked questions concerning your medical history. During the same visit you will have your blood drawn for routine screening and genetic testing. You will also be asked to collect a urine sample for routine screening. If the doctor finds that you are a healthy candidate you will be invited to participate in the second part of the study. During Phase II, the investigators will perform physiological tests after you are placed on a low salt diet and again after you are placed on a higher salt diet. If you are on blood pressure medication, it may be necessary to discontinue taking your present medication for up to three months before beginning the study. Patients discontinuing their current blood pressure medication may be placed on a different blood pressure medication during this 'washout' period if necessary to maintain blood pressure at pre-study levels. Once your blood pressure medications are discontinued, you will be closely monitored. If you do not own a home blood pressure monitor, the investigators will provide one for you to use during the study so that you can keep a daily record of your blood pressure readings. The investigators will ask you to call us every three days to report your blood pressure readings. After you have stopped taking your medication, dieticians at the hospital will make you low salt meals to eat at home for about seven days. On the last day of the low salt diet, you will be asked to begin a 24-hour urine collection that you will bring with you when you are admitted to the hospital that evening. That morning, you will be required to come to the Center for Clinical Investigations (CCI) at Brigham and Women's Hospital for a one-hour test to check if your body is in the correct salt balance. You will return that evening to the CCI where you will be admitted for your study that will occur the next morning. On the morning of your low salt study, the investigators will collect some blood samples. The investigators will also take ultrasound pictures of your heart to see how salt and hormones affect the way your heart and blood vessels functions. These tests will last approximately 5 hours and you will be discharged around 2:00 PM. For the next 5-7 days, you will be placed on a high salt diet. During this diet period, you will eat all your own food, but the investigators will give you some supplements to add to your meals. After 5-7 days on your high salt diet, on the morning of your second admission to the hospital, you will be asked to begin a final 24-hour urine collection. That morning, you will again be required to come to the CCI for a blood test, and you will return later that evening to the inpatient CCI where you will be admitted for your final overnight study. The same study that was done for the low salt diet will be repeated for the high salt study. You will be discharged at around 2:00 p.m. These studies will help to determine if you are salt-sensitive. In addition, the investigators hope to learn more about the hormones that regulate your blood pressure and the genes responsible for regulating those hormones. You will have the option to spend a second night in the CCI after each diet phase in order to participate in an optional study of the blood vessels in the arm. This study also uses an ultrasound machine. It will last about 2 hours in the morning. You will be placed back on your initial blood pressure medication (if you are on any) and returned to your regular physician for care. The investigators can also provide clinically relevant information to you.

NCT01426529 Hypertension Insulin Resistance Drug: Para-aminohippuric Acid Drug: Angiotensin II Drug: Norepinephrine
MeSH: Insulin Resistance
HPO: Insulin resistance

We will recruit hypertensive subjects who will be classified into two groups according to genotype status at rs926198 of CAV-1.

Primary Outcomes

Description: We are testing our hypothesis that genetic variation at the cav-1 locus is a determinant of vascular phenotypes in hypertensive subjects. We will recruit hypertensive subjects who will be classified into two groups according to genotype status at rs926198 of CAV-1. Vascular function status will be determined using four markers: renal blood flow (primary endpoint), brachial artery reactivity, aortic compliance, and blood pressure levels. We will assess these endpoints before and after two provocations: low vs. high salt intake and AngII infusion.

Measure: Genetic Variation at the Caveolin-1 Locus

Time: 5 years
