RESUMO
From January 1979 until December 1980, neutralizing antibody titres to Coxsackie B1-6 viruses were measured in sera from 220 patients presenting to a general medical unit, the majority of whom had chest pain. No four-fold or greater rises in antibody titre were detected in these hospital patients. However, 49 per cent had titres of greater than or equal to 256 to one or more Coxsackie B virus types compared with 10 per cent of the 950 persons studied during a 'normal population' survey in the West of Scotland. When a more rigorous threshold was adopted, titres greater than or equal to 512 were found in 33 per cent and 4 per cent respectively. We conclude that Coxsackie B infections are not uncommon in the practice of a general medical unit and that they may account for more cases of both acute and subacute left chest pain than is usually realised.
