Spironolactone in Adult Congenital Heart Disease

2014-07-23 21:10:27 | BioPortfolio

Summary

The purpose of this study is to see if the study drug called spironolactone reduces fibrous (stiffening) in heart muscle tissue and improves heart function. Subjects from the study titled "Heart Failure in Congenital Heart Disease: the role of myocardial fibrosis" who have evidence of heart dysfunction and/or evidence of fibrosis (stiffening) in the heart muscle will be asked to take part in this study.

This study will include randomizing the subject to receive the study drug or placebo. Randomization will occur during visit 1.

Visit 1 will include the following:

- Subjects will answer questions about how well they can breathe.

- An MRI. Dye called gadolinium will be injected into the subject's vein.

- They will go to the Oregon Clinical and Translational Research Institute where 2 tablespoons of blood will be drawn from an intravenous (IV) catheter (tube).

- They will do a 6 minute walk test..

- They will also have an echocardiogram, which is a test that looks at the movement of the subject's heart. A technician will place a cool jelly on their chest and use a small wand to take pictures through the skin.

Subjects' will also have visits 3-6 weeks, 3, 6, 9 months, and 12 months after randomization. Visits 2-5 will include the following:

- They will go to the Oregon Clinical and Translational Research Institute where 1/2 tablespoon of blood will be drawn.

- They will do a 6 minute walk test. During this test, they will walk back and forth in a hallway. The goal is to walk as far as possible for 6 minutes. Subjects will probably get out of breath or become exhausted. If they do, they can slow down, stop, or rest as they need to. Blood pressure will be taken before the walk.

- They will have a health review at 6 months.

Visit 6 will be identical to visit 1 and include the following:

- Subjects will answer questions about how well they can breathe.

- An MRI. Dye called gadolinium will be injected into the subject's vein.

- They will go to the Oregon Clinical and Translational Research Institute where 2 tablespoons of blood will be drawn from an intravenous (IV) catheter (tube).

- They will do a 6 minute walk test..

- They will also have an echocardiogram, which is a test that looks at the movement of the subject's heart. A technician will place a cool jelly on their chest and use a small wand to take pictures through the skin.

The investigators will compare the study drug, called spironolactone, to placebo with regard to any changes in heart stiffening and function of the heart.

Medical and Biotech [MESH] Definitions

Cardiac manifestation of systemic rheumatological conditions, such as RHEUMATIC FEVER. Rheumatic heart disease can involve any part the heart, most often the HEART VALVES and the ENDOCARDIUM.

Occlusion of the outflow tract in either the LEFT VENTRICLE or the RIGHT VENTRICLE of the heart. This may result from CONGENITAL HEART DEFECTS, predisposing heart diseases, complications of surgery, or HEART NEOPLASMS.

A potassium sparing diuretic that acts by antagonism of aldosterone in the distal renal tubules. It is used mainly in the treatment of refractory edema in patients with congestive heart failure, nephrotic syndrome, or hepatic cirrhosis. Its effects on the endocrine system are utilized in the treatments of hirsutism and acne but they can lead to adverse effects. (From Martindale, The Extra Pharmacopoeia, 30th ed, p827)

A congenital coronary vessel anomaly in which the left main CORONARY ARTERY originates from the PULMONARY ARTERY instead of from AORTA. The congenital heart defect typically results in coronary artery FISTULA; LEFT-SIDED HEART FAILURE and MITRAL VALVE INSUFFICIENCY during the first months of life.

Disease-related laceration or tearing of tissues of the heart, including the free-wall MYOCARDIUM; HEART SEPTUM; PAPILLARY MUSCLES; CHORDAE TENDINEAE; and any of the HEART VALVES. Pathological rupture usually results from myocardial infarction (HEART RUPTURE, POST-INFARCTION).
