Svend Aage Mortensen


Svend Aage Mortensen, M.D., Sc.D. was a Danish cardiologist at Rigshospitalet in Copenhagen, Denmark. Rigshospitalet was until February 2017 the largest hospital in Denmark; only surpassed by Skejby Sygehus, however, Rigshospitalet is a flagship in the Danish health care system. From 1990 until his death in 2015, Mortensen was the medical director of the heart transplantation unit at Rigshospitalet. He was a fellow of the European Society of Cardiologists. Mortensen is best known as the chief researcher and the leading author for the Q-Symbio study of the “Effect of Coenzyme Q10 on Morbidity and Mortality in Chronic Heart Failure.”
Coenzyme Q10 Research
Mortensen is best known as the chief researcher and the leading author for the Q-Symbio study of the “Effect of Coenzyme Q10 on Morbidity and Mortality in Chronic Heart Failure.
The Q-Symbio study was a multi-center, randomized, double-blind, placebo-controlled study that investigated the effectiveness of adjunctive treatment of chronic heart failure patients with daily Coenzyme Q10 supplements in the ubiquinone form. The patients took 300 milligrams of Coenzyme Q10 or matching placebos for two years-
The results from the Q-Symbio study showed significantly improved symptoms and survival for the patients taking the active Coenzyme Q10 treatment together with their conventional heart failure medications.
Multiple treatment options with Coenzyme Q10
As a cardiologist, Mortensen saw multiple treatment options with Coenzyme Q10 in cardiovascular disease:
New guidelines for the management of heart failure
Following the publication of the results of the Q-Symbio study, Mortensen urged that the American College of Cardiology/American Heart Association guidelines for the management of heart failure be revised to include adjunctive treatment with the natural substance Coenzyme Q10.
He summarized the case for Coenzyme Q10 as an adjunctive treatment for heart failure:
Coenzyme Q10 and the “energy starved heart”
Mortensen's research prior to the Q-Symbio study had convinced him of the importance of adequate Coenzyme Q10 for the heart muscle cells:
Concern for heart failure patients
Mortensen's highest concern was the welfare of his heart failure patients and heart transplantation patients. He knew that heart failure is a disabling disease that diminishes the quality of life of the patients. It is a disease with an increasing prevalence. It is a disease that continues to have a poor prognosis even though advances have been made in various drug and medical device therapies.
Mortensen's research established Coenzyme Q10 adjunctive treatment as a way to improve heart failure outcomes and break the metabolic vicious cycle in the heart muscle.
