A revision is made of the periodic publications specializing in cardiology that at present are being edited in the world. Ninety-nine titles of actual importance with a perioricity over two numbers per year formed the material of study. The oldest publication began to be printed in the year of 1908, changed name in 1937, and today is titled Archives des Maladies du Coeur et de Vaisseax. In Spanish, the first journal specializing in cardiology started in Mexico 50 years ago; in 1944 it changed name, and at present in continues to be published with the title of Archivos del Instituto de CardiologĂa de MĂ©xico. In the first decade of this century, only one publication on cardiology with the above mentioned characteristics appeared. In the first seven months of 1979, five appeared.
