Industry Relationships

Cleveland Clinic physicians and scientists may collaborate with the pharmaceutical or medical device industries to help develop medical breakthroughs or provide medical expertise or education. Cleveland Clinic strives to make scientific advances that will benefit patient care and support outside relationships that promise public benefit. In order for the discoveries of Cleveland Clinic physicians' and scientists' laboratories and investigations to benefit the public, these discoveries must be commercialized in partnership with industry. As experts in their fields, Cleveland Clinic physicians and scientists are often sought after by industry to consult, provide expertise and education.

To assure professional and commercial integrity in such matters, Cleveland Clinic maintains a program that reviews these collaborations and, when appropriate, puts measures in place to minimize bias that may result from ties to industry. Cleveland Clinic publicly discloses the names of companies when (i) its physicians/scientists receive $5,000 or more per year (or, in rare cases, equity or stock options) for speaking and consulting, (ii) its physicians/scientists serve as a fiduciary, (iii) its physicians/scientists receive or have the right to receive royalties or (iv) its physicians/ scientists hold any equity interest for the physician's/scientist's role as inventor, discoverer, developer, founder or consultant.* In publicly disclosing this information, Cleveland Clinic tries to provide information as accurately as possible about its physicians' and scientists' connections with industry.

As of 4/22/2021, Dr. Helguera has reported no financial relationship with industry that is applicable to this listing. In general, patients should feel free to contact their doctor about any of the relationships and how the relationships are overseen by Cleveland Clinic.

Public Health Service-Reportable Financial Conflicts of Interest. Cleveland Clinic scientists and physicians engage in basic, translational and clinical research activities, working to solve health problems, enhance patient care and improve quality of life for patients.

My husband and I both had appointments for pacemaker monitoring. We were particularly impressed with the positive, cheerful attitude exhibited by every staff member! Covid-19 has made even the most routine checkups a reason for concern, and heightened the extreme attention to masks, hand sanitizing, equipment cleaning, distancing, etc. The cheerful greetings and personal attention shared by everyone, including the lab technician and our wonderful doctor, were invaluable in alleviating our concerns!

Dr Helguera was very informative in laymen's terms with the issue I had

Reviewed on Jun 8, 2020

When I arrived a nurse came in and asked me questions and took my blood pressure. It was high, 170 over something. She then left and I waited in the office for 25 minutes. She then came back and said that the doctor wanted to order a test for me. I asked why he would order a test when I had not even seen him. She said "you have not seen him"? She then left and a few minutes later the doctor came in. He said he was sorry for the wait. He did not take my blood pressure and proceeded to tell me that he was changing my prescription adding two prescriptions and that I should stop one of my prescriptions. He also said I should go on a heart monitor for a month. They then ordered the heart monitor. It has been 3 weeks and I decided not to go along with the changes he had made and the heart monitor never arrived, which is fine since I did not do as he had instructed and therefore would not need the monitor. We drove for 5 hours to see this doctor and had to stay overnight in Weston. To say I was not pleased is an understatement.
