Lipoprotein(a) as an emerging target

Heart disease is the leading cause of death worldwide, but it’s also one of medicine’s biggest success stories. Since the 1950s, the risk of dying from cardiovascular disease has fallen dramatically, thanks to public health efforts, emergency care, medical innovation, and surgeries.

In this episode, Jacob and Saloni explore the cholesterol revolution: from statins discovered in fungi to new drugs that cut LDL cholesterol by 60% and last for months, driven by breakthroughs in genetics, monoclonal antibodies, RNA therapies, and modern medicinal chemistry. They talk about how cholesterol travels through the bloodstream, how it causes atherosclerosis and heart disease, and why it took nearly a century for scientists to form the consensus that lowering cholesterol saves lives.

Hard Drugs is a podcast from Works in Progress and Coefficient Giving about medical innovation presented by Saloni Dattani and Jacob Trefethen.

Correction: In the episode, Saloni makes an error in converting the number of heartbeats per lifetime. It is roughly 2.5 billion beats, not a trillion.
