New Boston Medical Center Study shows a relationship between heart disease and spontaneous loss of Y chromosome

Researchers found that men with a higher proportion of blood cells missing the Y chromosome have a higher risk of dying from heart failure. Elevated Y chromosome loss is associated with decreased treatment response in patients with transthyretin cardiac amyloidosis, a progressive disease causing heart failure and death.

With $12 million NIH grant renewal, Lewis Katz School of Medicine researchers to explore novel cell mechanism in heart injury and repair

Researchers at the Lewis Katz School of Medicine will investigate how injured heart cells communicate with other cells throughout the body using microvesicles known as exosomes. The study aims to understand how specific molecules, such as microRNAs, facilitate communication pathways between cells in the heart and vasculature.

More than a quarter of ‘healthy’ over-60s have heart valve disease, according to new research

A study of over 4,500 healthy adults aged 60 and older found that nearly 28% had some form of heart valve disease, with age being the main risk factor. The majority of cases were mild, but the study highlights the need for more research into screening methods to identify and manage the disease in the elderly population.
