Amyloidosis Incidence in High-Risk Cardiac Device Patients

Study Purpose

This single-practice prospective cohort study aims to enhance the diagnosis of cardiac amyloidosis in high-risk patients undergoing standard cardiac device implantation. By analyzing chest wall fat tissue, which is usually discarded, we aim to determine the diagnostic yield of such biopsies for amyloidosis and to develop a predictive screening model based on clinical, lab, and imaging data. The study, running from December 2023 to December 2024, expects to enroll 100 patients and may provide a new, non-invasive diagnostic avenue for this condition.

Recruitment Criteria

Accepts Healthy Volunteers Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms	No
Study Type An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes. An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes. Searching Both is inclusive of interventional and observational studies.	Observational
Eligible Ages	40 Years and Over
Gender	All

More Inclusion & Exclusion Criteria

Inclusion Criteria:

- Patients who are 40 years of age or older.

- Patients who are able and willing to provide informed consent.

- Patients who are scheduled for CIED implantation within the study period and with clinical lab and imaging features suggestive of cardiac amyloidosis.

Exclusion Criteria:

- Individuals below the age of 40.

- Persons who are unable to consent or who do not consent to participate.

- Patients who have already been diagnosed with cardiac amyloidosis prior to the study

Trial Details

Trial ID: This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.	NCT06186167
Phase Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans. Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data. Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs. Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.

Additional Details

The study targets a key gap in cardiac amyloidosis diagnosis by systematically evaluating the histopathological incidence of the disease using chest wall fat pad biopsies-tissue that is typically discarded during the implantation of cardiac devices like pacemakers, ICDs, and CRT-D/Ps. Standard surgical procedures are adhered to, ensuring minimal additional risk to patients. The collected tissue samples are analyzed by the HCA pathology laboratory to detect amyloid deposits, thereby potentially identifying amyloidosis in a non-invasive manner. In addition to the primary endpoint of histopathological diagnosis, the study retrospectively aims to validate a predictive model that incorporates a wide range of data to streamline the identification of patients at high risk for cardiac amyloidosis. Strict measures are in place to protect patient confidentiality and data security. By potentially improving diagnostic efficiency, this research could contribute to earlier detection and treatment strategies, thus improving patient outcomes for those at high risk of this life-threatening condition.

Arms & Interventions

Arms

: High-Risk Cardiac Device Recipients

Participants in this cohort are individuals undergoing clinically indicated cardiac device implantation, such as pacemakers, ICDs, ILRs, or CRT-D/Ps. During the standard implantation procedure, chest wall fat tissue typically excised to create space for the device is collected for histopathological analysis to identify amyloid deposits. This study involves no additional intervention beyond the routine clinical care received by the patients.

Interventions

Procedure: - Chest Wall Fat Tissue Collection

As part of routine cardiac device implantation, chest wall fat tissue is collected for histopathological analysis. This tissue, which is typically discarded, will be used to identify amyloid deposits in high-risk cardiac patients. No additional surgical intervention is performed beyond the standard procedure for device implantation.
