Heart disease has remained a serious issue faced by both men and women. However, a recent study uncovers and explains that minerals that block heart valves in men are different from those that affect women.Using the Canadian Light Source (CLS) at the University of Saskatchewan, Marta Cerruti, an Associate Professor in McGill's Department of Materials Engineering, and her team analyzed damaged heart valves from patients who had undergone transplants.Recently published in Acta Biomaterialia, the team's findings show considerable differences in the mineral deposits found in aortic valves of men and women who suffer from stenosis, a life-threatening heart condition caused by a narrowing of the aortic valve opening."What we showed, which was a surprise to us, is that the type of minerals in the heart valves is different between the sexes," said Cerruti."We unexpectedly found that the minerals are different in composition and shape and that they grow slower in women," Cerruti added.Mineral composition analysis performed at the Soft X-Ray Mischaracterization Beamline, which is housed within the CLS, also determined that a type of mineral deposit was found almost exclusively in samples from female patients.Cerruti says that her findings demonstrate the importance of thinking about diversity in the context of research, a concept that has historically been a blind spot for the scientific community. For example, using only male mice in experiments used to be standard practice."Our study is the perfect illustration that by only looking at a specific population, you will skew your data," she says."Having a more diverse data set improves your science," she added.With 280,000 heart valves being replaced every year in Canada due to stenosis, Cerruti said that her work demonstrates the need to develop different diagnostic and therapeutic approaches when treating aortic stenosis in men or women.In order to make that happen, Cerruti's group will return to the CLS to further investigate this cardiovascular phenomenon and understand the precise composition of the mineral deposits they found in women."Understanding what the minerals are could definitely help to develop a cure," she said."It's possible that there could be easier ways to target these minerals and dissolve them for women," she added.( With inputs from ANI )
