In 2023, Japan's share of the world's top 10% most-cited publications in cardiology and cardiovascular medicine was 4.89%. Forecasted data from 2024 to 2028 shows a steady decline, with the share decreasing from 4.87% to 4.82%. The year-on-year decrease remains marginal, averaging a compound annual growth rate (CAGR) of -0.29% over the forecast period.

Future trends to watch for:

Potential impacts of increasing investments in scientific research and development in other regions, which could affect Japan's share.
Technological advancements and strategic collaborations, which may enable Japan to mitigate the declining trend.
Emergence of new research areas within cardiology could shift focus and influence citation patterns.
