Cardiac disease construction on the borderland

A Century of Cardiomythology: Exercise and the Heart c.1880–1980

The relationship between health and exercise involves risks as well as rewards. This article focuses on heart disease and the marathon to show how doctors have negotiated that relationship over a century. Three distinct changes in biomedical attitudes towards vigorous exercise are outlined. First, the mid-Victorian interpretation of pathological hypertrophy of the heart was overturned at the end of the nineteenth century. Secondly, hypertrophy was reinvented as a beneficial physiological adaptation in the 1940s and 1950s. Thirdly, these claims of distinctiveness were challenged by the leisure revolution. Sports doctors and cardiologists reinvented exercise as a drug that could only be safely used with the guidance of a medical professional. Medicalising sport reduced its risk and maximised its reward, both to the individual and the state.

Articulating silences: experiential and biomedical constructions of hypertension symptomatology

In this article, we explore the flexible configuration of a local knowledge system about hypertension symptoms, foregrounding it against prevailing biomedical assertions regarding the asymptomatic or "silent" nature of hypertension. The complex and coherent knowledge system held by older African Americans living in a southern, rural community stands in contrast to the current scientific discourse and local biomedical perspectives on hypertension symptomatology. The older African American participants in this study apply local knowledge of hypertension symptomatology to make health decisions nearly every day. Despite this, most biomedical practitioners maintain a distance from these lay sources of knowledge, often remaining stalwart in their refusal to recognize the existence or influence of symptoms. We conclude that authoritative knowledge ultimately lies in the minds and bodies of the elders, who have encountered symptoms as guideposts that direct action, rather than with a biomedical "reality" that is yet unresolved.
