"Approximately 20% of individuals have high Lp (a),"
says Dr. George Thanassoulis, who is a researcher at the RI-MUHC and
principal author of the study "We hope that our work will raise
awareness that individuals with high Lp(a) are at high risk of heart
disease and hopefully stimulate the development and testing of new
