rnishimura@mayo.edu Clinical Profile


The research interests of Rick A. Nishimura, M.D., center on cardiovascular hemodynamics and its application to patients with diseases of the heart muscle and heart valves (structural heart disease). Dr. Nishimura and colleagues have used combined cardiac catheterization and Doppler echocardiography to further understand the pathophysiology of valvular heart disease as well as myocardial and diastolic functions of the heart. Their published manuscripts include work with combined Doppler and catheterization correlations.

Dr. Nishimura has a special interest in the cardiomyopathies, particularly hypertrophic cardiomyopathy, as well as in valvular heart disease. His team has investigated the diagnosis and treatment of patients with these diseases. The team is actively involved in clinical research investigating catheter-based therapies to treat patients with myocardial and valvular heart disease.

Finally, Dr. Nishimura is leading an institutional effort — called the Knowledge Management Program — to provide the optimal Mayo Clinic-vetted knowledge to Mayo physicians through electronic systems, to be used at the point of care.

Focus areas

  • Hypertrophic cardiomyopathy. Dr. Nishimura investigates the optimal treatment of patients with this disease as well as risk stratification to prevent sudden death.
  • Valvular heart disease. Research is aimed at determining the optimal timing of intervention for patients with valve disease as well as investigating new catheter-based procedures for treatment of patients with valve disease.
  • Knowledge management. Dr. Nishimura works to provide doctors at Mayo Clinic with the most updated clinical knowledge, vetted by other Mayo physicians.

Significance to patient care

Cardiologists from all over the country are sending specific patients to Mayo's Hypertrophic Cardiomyopathy Clinic and Valvular Heart Disease Clinic to obtain cutting-edge technology in diagnosis and treatment.

The Knowledge Management Program will assure that all patients coming to any Mayo facility will receive the optimal and safest care, as outlined by Mayo experts.
