About this unit

With the heart pumping 24/7, it’s crucial that things flow smoothly (pun intended!). Unfortunately, this isn’t always the case. The underlying reasons for circulatory system problems vary from your genes to your lifestyle. To combat this growing problem in the world, we need a better understanding of these diseases.
