On the occasion of warmly celebrating the 50th anniversary of the founding of Chinese Journal of Cardiovascular Diseases, I sincerely thank a generation of grandmasters in the field of cardiovascular diseases in China for founding this professional journal in such a difficult era 50 years ago, and deeply remember their outstanding contributions to China's cardiovascular cause! They were far-sighted and worked hard. At the beginning of the establishment of cardiovascular discipline, they established a platform for cardiovascular academic exchange and vigorously promoted the development of cardiovascular discipline. In the past 50 years, the journal has published many important research results, conducted exchanges and discussions, and spread a large amount of new knowledge, new methods and new views to the majority of cardiovascular professionals in time, which has greatly promoted the progress and development of cardiovascular disease prevention and treatment in China.
