Latin America has dramatically increased the number of articles Publisher from 1995 to 2002, but the individual contribution of each country appears to be very unequal. ⋯ The scientific production in Cardiology from Latin America shows dramatic differences among the countries, and Brazil, Mexico, and Argentina alone provide 80% of the publications. Brazil seems to have led the region for 20 years, especially since 1998. From the quality of the articles point of view, considering the impact factor, Chile and Argentina appear to be better positioned.
