Medicine
Clinical focus
Dr. Chad Weldy is a cardiologist with specialized expertise in the care of patients and families affected by inherited cardiovascular disorders, including cardiomyopathies, arrhythmia syndromes, and rare genetic heart diseases.
He provides clinical care through Stanford’s Center for Inherited Cardiovascular Disease (SCICD), where he trained under Dr. Euan Ashley and works within a multidisciplinary program integrating cardiovascular genetics, advanced imaging, and precision medicine.

Precision medicine and inherited heart disease
Dr. Weldy’s clinical and academic work focuses on understanding how genetic variation influences cardiovascular phenotypes, disease progression, and treatment response. His research and clinical scholarship emphasize:
- Genotype-phenotype relationships in inherited cardiomyopathies
- Clinical implementation of genetic testing and variant interpretation
- Translational pathways from human genetics to patient-specific therapy
- Integration of biobanks, electronic health records, and molecular data in clinical care
This work informs a precision-medicine approach to cardiovascular disease, particularly in patients with complex or rare inherited conditions.

Clinical care and referrals
Patients are seen through Stanford’s inherited cardiovascular disease programs. Referrals typically involve:
- Suspected or confirmed inherited cardiomyopathy
- Family history of sudden cardiac death or inherited arrhythmia
- Genotype-positive individuals requiring clinical surveillance
- Integration of genetic testing into cardiovascular care
