  Coronary artery disease (CAD) is a major cause of death and disability in
developed countries. Although CAD mortality rates worldwide have declined over
the past 4 decades, CAD remains responsible for approximately one-third or more
of all deaths in individuals over age 35, and it has been estimated that nearly
half of all middle-aged men and one-third of middle aged women in the United
States will develop clinical CAD. The present paper attempts to check the
applicability of Lotka's Law on South African publication on Coronary artery
disease research. The study lights on Lotka's empirical law of scientific
productivity, i.e., Inverse Square Law, to measure the scientific productivity
of authors, to test Lotka's Exponent value and the K.S test for the fitness of
Lotka's Law.
