2. Introduction
An accomplished cardiologist, Dr. Rajan Bhatt cares for
patients at Spectrum Dermatology & Vein Center in
Scottsdale, Arizona. Dr. Rajan Bhatt is also a respected
clinical researcher and has published peer-reviewed papers
on studies he has conducted on coronary artery disease and
related conditions.
In January of 2018, the journal Circulation: Cardiovascular
Genetics published an article on the development of a
polygenic risk test for coronary artery disease. Researchers at
Laval University, McMaster University, and the Population
Health Research Institute (PHRI) in Canada created the
metric, based on their review of the genotypes of more than
111,000 subjects in the UK Biobank.
3. Coronary Artery Disease Risk
From this information, the team identified 182 genetic
variants linked to coronary artery disease.
Using the resultant polygenic risk score, known as GRS182,
the team found that higher numbers correlated with the
development of early-onset coronary artery disease
(EOCAD). The association proved comparable to, yet
independent from, other risk factors, which indicated that
polygenic testing can be a clinically useful tool for risk
evaluation. Researchers suggest that when combined with
currently available genetic testing, polygenic testing can
contribute to a 500 percent increase in identified cases of
EOCAD.
