Identification of a genetic etiology in ESHF has important prognostic and family implications. However, genetic testing practices are understudied in patients with ESHF.<h4>Methods</h4>This single-center, retrospective study included consecutive patients with ESHF who underwent heart transplantation (HT) or left ventricular assist device (LVAD) implantation between 2018 and 2023. Data, including genetic testing and pathology reports, were collected from the electronic medical records. Analyses of demographic and clinical characteristics were stratified by genetic-testing completion and the presence of clinically actionable variants. Logistic regression was performed to evaluate for associations between histology findings and genetic variants.<h4>Results</h4>A total of 529 adult patients (mean age 57 years) were included in the study and were predominantly male (79%, 422/529) and non-white (61%, 322/529). Genetic testing was performed in 54% (196/360) of patients with either nonischemic or mixed CMs. A clinically actionable result was identified in 36% (70/196) of patients, of whom only 43% (30/70) had genetic counselor referrals. The most common genetic variants were TTN (32%, 24/75), MYBPC3 (13%, 10/75) and TTR (11%, 8/75). Clinically actionable variants were identified in patients with known heart failure precipitators such as alcohol use. In multivariable analysis, the presence of interstitial fibrosis, specifically diffuse, on pathology was significantly associated with a clinically actionable variant (aOR 2.29, 95% CI [1.08-4.86]; P = 0.03).<h4>Conclusion</h4>Patients with ESHF and with nonischemic or mixed CM who were undergoing advanced therapies had low uptakes of genetic services, including testing and counselors, despite high burdens of genetic disease. Pathology findings such as interstitial fibrosis may provide insight into genetic etiology. The underuse of services suggests a need for implementation strategies to improve uptake.","is_dataset_classified":null,"base_score":2.1972245773362196,"endowment":2.1972245773362196,"datacite_reuse_total":0,"file_count":0,"downloads":0,"views":0,"has_version_chain":false,"is_dataset":false,"is_oa":false,"pmid":"39454940","pmcid":null,"openalex_id":"https://openalex.org/W4403682076","authors":[],"funders":[{"funder_name":"American Heart Association Inc","grant_id":"","title":null}],"total_grants":1,"fwci":2.37,"citation_percentile":0.90421149,"influential_citations":0,"citation_trend":[{"year":2025,"count":3},{"year":2026,"count":5}],"oa_status":"bronze","license":"http://creativecommons.org/licenses/by-nc-nd/4.0/","oa_locations":[{"url":"https://onlinejcf.com/article/S1071-9164(24)00885-6/pdf","host_type":"journal"},{"url":"https://onlinejcf.com/article/S1071-9164(24)00885-6/pdf","host_type":"publisher"},{"url":"https://api.elsevier.com/content/article/PII:S1071916424008856?httpAccept=text/xml","host_type":"publisher"},{"url":"https://api.elsevier.com/content/article/PII:S1071916424008856?httpAccept=text/plain","host_type":"publisher"},{"url":"https://doi.org/10.1016/j.cardfail.2024.09.015","host_type":"journal"},{"url":"https://pubmed.ncbi.nlm.nih.gov/39454940","host_type":"repository"}],"fields_of_study":["Cardiomyopathy and Myosin Studies","Cardiac electrophysiology and arrhythmias","Neurogenetic and Muscular Disorders Research","Humans","Male","Female","Middle Aged","Heart-Assist Devices","Heart Transplantation","Retrospective Studies","Genetic Testing","Heart Failure","Aged","Adult"],"mesh_terms":["Adult","Aged","Female","Genetic Testing","Heart Failure","Heart-Assist Devices","Humans","Male","Middle Aged","Retrospective Studies","Heart Transplantation"],"keywords":["Medicine","Cardiology","Heart transplantation","Pathological","Heart failure","Internal medicine","Stage (stratigraphy)","Transplantation","Ventricular assist device","Intensive care medicine","Cardiomyopathy","Genetic Counseling","Genetic Testing","Heart Transplant","Left Ventricular Assist Device","Advanced Therapies","Cascade Testing"],"sdg_mappings":[{"sdg_number":0,"sdg_label":"Good health and well-being"}],"linked_datasets":[],"clinical_trials":[],"software_tools":[],"database_accessions":[],"source":"live","citation_network_status":"fetched"},"created_at":"2026-08-03T08:02:59.600897Z","pmid":null,"pmcid":null,"fwci":null,"citation_percentile":null,"influential_citations":0,"oa_status":null,"license":null,"views":0,"total_file_size_bytes":0,"version_count":0,"fair_f":null,"fair_a":null,"fair_i":null,"fair_r":null,"fair_zscore":null,"fair_rationale":null,"fair_model":null,"fair_agent_version":null,"fair_fulltext_source":null,"fair_has_llm":null,"fair_computed_at":null,"clinical_trials":[],"software_tools":[],"db_accessions":[],"linked_datasets":[],"topics":[]}
