The Quest for Pacemaking Cardiomyocytes to Engineer Biopacemakers - Debora Lieu

Deepak Srivastava, MD, explores how cellular reprogramming offers new hope for treating heart disease. He highlights innovative strategies to regenerate damaged heart tissue by stimulating adult cardiomyocytes to divide and converting fibroblasts into heart-like cells. His team develops a nonviral delivery system using lipid nanoparticles and investigates the role of specific gene regulators in restoring heart function in animal models. Srivastava also discusses a potential oral therapy for aortic valve disease, driven by insights into cellular fate changes caused by NOTCH1 mutations and telomere shortening. Additionally, he reveals how trisomy 21 may trigger congenital heart defects by altering the identity of specialized heart cells. Through pioneering research in genetics and regenerative medicine, Srivastava demonstrates how understanding developmental biology can lead to transformative clinical advances.

Dr. Robert Baron reviews best practices in lipid management for preventing cardiovascular disease, with a focus on statin use. He outlines the strong evidence for statins in reducing heart attack and stroke risk by 25–33%, particularly in patients with clinical atherosclerotic disease, diabetes, or high LDL. He explains why shared decision-making is key in primary prevention, where guidelines vary and risk thresholds are debated. Baron discusses the shift to the newer PREVENT risk calculator, which offers improved accuracy and removes race as a factor. He also explains when additional lipid-lowering medications may be appropriate and clarifies the impact of risk-enhancing factors like family history, coronary artery calcium, and LP(a).
