About this study
To map the genetic defect responsible for familial hypertrophic cardiomyopathy.
Read the detailed description
BACKGROUND:
Familial hypertrophic cardiomyopathy is a disease of heart muscle that is genetically transmitted as an autosomal dominant trait, with a high degree of penetrance. Affected individuals typically have asymmetric thickening of the interventricular septum often involving the adjacent left ventricular free wall. Histologically, myocardial cells are enlarged and muscle bundles are grossly disorganized, producing a whorled pattern. The physiologic consequence of this cardiomyopathy is diastolic dysfunction with impaired ventricular relaxation and elevated diastolic pressures in the heart and pulmonary vasculature. Patients can experience dyspnea, angina, palpitations, and syncope. Complications of the disease include atrial fibrillation, congestive heart failure, thromboembolism, and most importantly, sudden death.
DESIGN NARRATIVE:
The three kindreds studied included one in Iceland, one in the St. Lawrence region in Canada, and one in the Pittsburgh, Pennsylvania area. Pedigrees were established for the three kindreds. All family members were clinically evaluated by physical exam, electrocardiogram, and comprehensive M-mode and two-dimensional echocardiography. Lymphoblastoid cell lines were derived from all members of the three pedigrees. Restriction fragment length polymorphism analyses were used to identify a DNA probe that was linked to familial hypertrophic cardiomyopathy. Studies were conducted to determine if the familial hypertrophic cardiomyopathy locus was the same in all three kindreds and to identify the gene responsible.
The study completion date listed in this record was obtained from the "End Date" entered in the Protocol Registration and Results System (PRS) record.

Questions about this trial
What is this clinical trial studying?
An observational study of Cardiovascular Diseases and Heart Diseases, run by National Heart, Lung, and Blood Institute (NHLBI).
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 16 Mar 2016. Status can change between updates, so confirm with the study contact before making plans.
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?
On the ClinicalTrials.gov record for NCT00005251, which also lists 14 linked publications.
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 16 Mar 2016.
