This week's edition of JACC This Week brings Dr. Carolyn Lam and Dr. Harlan Krumholz into a deep exploration of a special issue devoted to innovative cardiovascular research emerging from China. As they highlight newly published studies and their global significance, they reflect on how scientific progress accelerates when discoveries are shared across regions and cultures. Their conversation reinforces a central message: advancing cardiovascular health requires collective effort, open exchange, and a commitment to evaluating science based on quality—not geography.

Drs. Carolyn Lam and Harlan Krumholz unpack new JACC research on cardiometabolic health, highlighting how COVID‑19 shaped cardiovascular care, mortality patterns, and disparities. They also break down updated evidence on PREVENT risk equations in young adults, gaps in lipid testing and statin use, and what these findings mean for modern cardiovascular prevention and population health.
