What are heart attacks? Rethinking some aspects of medical knowledge.

There has been a modern epidemic of heart attacks in the western world, and this paper is concerned with this 'new' medical condition and how it arose. Two competing theories are commonly proposed, relating either to conventional accounts of medical science, or to social construction. Whilst recognising that aspects of both theories have some validity, it is claimed that neither is wholly adequate. This issue has particular relevance for heart attacks and is explored in some detail, but it also points to some more general conclusions. First that medical knowledge cannot be separated into 'scientific' and 'social' compartments but is united by its human aspect; and second that although medical knowledge has a special dimension, when understood in this way, it may also resonate with a more general re-examination of the relationship between scientific and human knowledge.
