spironolactone and Cardiomyopathy, Hypertrophic

spironolactone has been researched along with Cardiomyopathy, Hypertrophic in 5 studies

Spironolactone: 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)
spironolactone : A steroid lactone that is 17alpha-pregn-4-ene-21,17-carbolactone substituted by an oxo group at position 3 and an alpha-acetylsulfanyl group at position 7.

Cardiomyopathy, Hypertrophic: A form of CARDIAC MUSCLE disease, characterized by left and/or right ventricular hypertrophy (HYPERTROPHY, LEFT VENTRICULAR; HYPERTROPHY, RIGHT VENTRICULAR), frequent asymmetrical involvement of the HEART SEPTUM, and normal or reduced left ventricular volume. Risk factors include HYPERTENSION; AORTIC STENOSIS; and gene MUTATION; (FAMILIAL HYPERTROPHIC CARDIOMYOPATHY).

Trial Overview

Trial Outcomes

Absolute Change in Serum Markers of Collagen Turnover (Micrograms/L) Over a One-year Follow-up Period in the Spironolactone Group Compared to Placebo.

Specific variables of collagen turnover markers that will be evaluated include markers of collagen synthesis (PINP, PIIINP), and marker of collagen degradation (ICTP). A two-sample t-test was used to compare the differences between these collagen turnover markers at baseline and the absolute differences in change from baseline to 12 months of follow-up. (NCT00879060)
Timeframe: The time points measured were at Baseline and at 12 Months (Follow-Up).

Assessment of Cardiac Mass and Fibrosis by Cardiac Magnetic Resonance Imaging (CMR) - Left Atrial Dimension (in mm)

CMR will be utilized as it has superior reproducibility (as compared to 2-D echocardiography). Late Gadolinium Enhancement (LGE) Assessment of myocardial fibrosis by CMR will be expressed as a percentage of left ventricular mass (%LV), maximum left ventricular wall thickness (in mm), left ventricular end-diastolic cavity size (in mm/m^2), and left atrial dimension (in mm). (NCT00879060)
Timeframe: The time points measured were at Baseline and at 12 Months (Follow-Up)

Assessment of Cardiac Mass and Fibrosis by Cardiac Magnetic Resonance Imaging (CMR) - Left Ventricular End-Diastolic (LVED) Cavity Size (in mm/m^2)

CMR will be utilized as it has superior reproducibility (as compared to 2-D echocardiography). Late Gadolinium Enhancement (LGE) Assessment of myocardial fibrosis by CMR will be expressed as a percentage of left ventricular mass (%LV), maximum left ventricular wall thickness (in mm), left ventricular end-diastolic (LVED) cavity size (in mm/m^2), and left atrial dimension (in mm). (NCT00879060)
Timeframe: The time points measured were at Baseline and at 12 Months (Follow-Up)

Measure of Functional Capacity: Peak Oxygen Consumption With Exercise

This data was collected at baseline, prior to drug administration, and again at 12-months of follow-up to determine if spironolactone improves a subject's functional capacity during exercise (peak oxygen consumption levels/peak VO2). Peak VO2 levels were measured in ml/kg/min. (NCT00879060)
Timeframe: The time points measured were at Baseline and at 12 Months (Follow-Up).

Measure of Heart Failure Symptoms According to the New York Heart Association Functional Class

This data was collected at baseline, prior to drug administration, and again at 12-months of follow-up to assess heart failure symptoms according to the New York Heart Association (NYHA) functional class, which is an estimate of a patients functional ability. The NYHA functional classes include: Class I (no limitation of physical activity), Class II (slight limitation of physical activity), Class III (marked limitation of physical activity), and Class IV (unable to carry out any physical acitivity without discomfort). (NCT00879060)
Timeframe: Time points were measured at Baseline and again at 12 months (follow-up)

Measure of Indices of Diastolic Function by Tissue Doppler Echocardiography (Septal E/e')

This data was collected at baseline, prior to drug administration, and again at 12-months of follow-up to measure indices of diastolic function by Tissue Doppler Echocardiography using the Septal E/e' ratio. (NCT00879060)
Timeframe: The time points measured were at Baseline and at 12 Months (Follow-Up).
