Cardiovascular diseases are leading causes of premature mortality and disability. Although health institutions have developed and promoted cardiac rehabilitation programs, they have not attained their desired outcomes, especially among the most vulnerable groups of the population. This study qualitatively examines socially and materially deprived men’s (n = 20) noncompliance with cardiovascular health guidelines following a medical intervention to the heart. By drawing on Pierre Bourdieu’s sociocultural theory of practice, results indicate that precarious living conditions obstruct long-term physical recovery and illness prevention by underemphasizing the value of "health capital" and reducing the capacity to sustain lifestyle change. This study calls into question health policies that have little to no consideration of embodied practical knowledge and lived experiences.
