S erious acute health events can be life-altering, because survivors can experience lasting reductions in functional status and quality of life. The ability to work and earn income-labour market outcomes-are important patientcentred outcomes 1 for individuals of working age, influencing economic well-being, sense of self and quality of life. 2,3 Health events may start a cascade where new disability causes earnings losses, which contribute to cost-related nonadherence to medication, 4 which contributes to worsened and even new health problems. 5,6 Lost productivity and informal care substantially contribute to the economic and societal consequences of health events. 7 Although interventions to ameliorate these consequences may be beneficial, a necessary first step to inform their design and testing is obtaining accurate data on the size of and risk factors for work and earnings losses after common health events in working-age populations. Cardiovascular and cerebrovascular diseases are the most common causes of death worldwide. 8 Specifically, the health events of acute myocardial infarction (MI), cardiac arrest and stroke are common causes of admission to hospital, increasing health care costs, disability and death. 9 One-third of acute MIs, one-quarter of strokes and 40% of cardiac arrests occur in people of working age who are aged 65 years or younger. 10-12 Prior studies of outcomes in the labour market after these health events have had serious methodological limitations or RESEARCH VULNERABLE POPULATIONS
