About this study

Official title: Relationship of Diastolic Function and Functional Capacity in Hypertrophic Cardiomyopathy: A Post-Hoc Analysis of Protocols 01-H-0066 and 96-H-0144

This study will examine the relationship between certain measures of heart function and exercise capacity in patients with hypertrophic cardiomyopathy (HCM).

Patients who participated in NHLBI studies 01-H-0006 ("Double Blind Placebo-Controlled Study of Pirfenidone - A Novel Anti-Fibrotic Drug - in Symptomatic Patients with Hypertrophic Cardiomyopathy Associated with Left Ventricular Diastolic Dysfunction") and 96-H-0144 ("Double Blind Placebo-Controlled Study of Long-Term Effects of Angiotensin-Converting Enzyme Inhibition (Enalapril) and Angiotensin II Receptor Blockade (Losartan) on Genetically-Induced Left Ventricular Diastolic Dysfunction") are eligible for this study. Data from echocardiograms and measures of left ventricular pressure obtained from patients in those studies will be analyzed in the current study to assess their influence on exercise capacity. No additional tests, treatments or other procedures are required.

Information from this study may help in the development of improved drug treatments for HCM.

Read the detailed description

NIH Protocols 01-H-0066, Double Blind Placebo Controlled Study of Pirfenidone A Novel Anti-Fibrotic Drug in Symptomatic patients with Hypertrophic Cardiomyopathy (HCM) Associated with left Ventricular Diastolic Dysfunction and 96-H-0144, Double Blind Placebo-Controlled Study of Long-Term Effects of Angiotensin Converting Enzyme Inhibition (Enalapril) and Angiotensin II Receptor Blockade (Losartan) On Genetically-Induced Left Ventricular Diastolic Dysfunction were undertaken to assess the effect of therapeutic interventions on left ventricular (LV) diastolic function. The relationship between baseline measures of diastolic function as assessed by noninvasive modalities such as Doppler echocardiography and radionuclide angiography, and qualitative and objective measures of functional capacity in patients without LV outflow tract obstruction has not been reported. In this protocol we will look at measures of LV geometry, relaxation and novel indices of ventricular compliance as they may influence measures of exercise capacity. In all cases, we will use pre-existing baseline data obtained with informed consent as part of the above protocols.

Questions about this trial

What is this clinical trial studying?

An observational study of Angina, Unstable and Myocardial Infarction, run by National Heart, Lung, and Blood Institute (NHLBI) at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 5 Oct 2018. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 5 Oct 2018.
