Peter H. Langsjoen  Short Biography

 

Peter H. Langsjoen, M.D., F.A.C.C. has been practicing cardiology 26 years since 1985.  After five years of invasive cardiology at the University of Texas Health Center at Tyler, Texas, he set up a private cardiology practice in Tyler and for the past 21 years has worked exclusively as a non-invasive cardiologist, specializing in congestive heart failure, primary & statin-induced diastolic dysfunction, and other diseases of the heart muscle.  Dr. Langsjoen has been involved with the clinical application of coenzyme Q10 (CoQ10) since 1983 when he began cooperating with his father, Per H. Langsjoen, M.D., F.A.C.C., the cardiologist who pioneered clinical research with CoQ10 in the United States and who performed the first human double blind controlled heart failure study with CoQ10 in the United States.  They practiced and performed research trials together up until Per’s death in 1993. 

 

Dr. Peter Langsjoen is a founding member of the Executive Committee of the International Coenzyme Q10 Association (www.ICQA.org), he is a Fellow of the American College of Cardiology, a member of the Alpha Omega Alpha Honor Society, American College of Physicians, Association of American Physicians and Surgeons, Texas Club of Cardiologists, Texas Medical Association and Smith County Medical Society.  Coenzyme Q10 continues to be a major part of Dr. Langsjoen's clinical practice as well as an ongoing research endeavor.  Over the past six years Dr. Langsjoen and his wife Alena have established a research laboratory in Tyler, Texas, for the measurement of both reduced and oxidized CoQ10 in both plasma and heart muscle.  Dr. Langsjoen lectures on coenzyme Q10 all over the world.

1990-present:  Private practice of non-invasive cardiology, Tyler, Texas, specializing in congestive heart failure, diastolic dysfunction and other diseases of the heart muscle.

 

Presentations at many conferences in countries worldwide, including the 6th, 8th and 9th International Symposiums on the Biomedical and Clinical Aspects of Coenzyme Q in Rome, Italy, 1990, in Stockholm, Sweden 1993 and in Ancona, Italy 1996, respectively and at the First, Third, Fourth and Fifth Conferences of the International Coenzyme Q10 Association in Boston, USA 1998, in London, UK 2002, in Los Angeles, USA 2005 and in Kobe., Japan 2007.

Ongoing research into application of coenzyme Q10 to the treatment of broad range of cardiovascular diseases, including long term follow up study in heart failure, in primary and statin-induced diastolic dysfunction, hypertrophic cardiomyopathy and in hypertensive heart disease.  Dr.  Langsjoen and his wife, Alena, have accumulated much experience in monitoring plasma levels of both reduced coenzyme Q10 (ubiquinol) and oxidized coenzyme Q10 (ubiquinone) by electrochemical detection since 2004.
