Mortality due to coronary heart disease has declined substantially since the 1970s (see Mortality from cardiovascular disease). This reduction can, in part, be attributed to better treatments, particularly in the acute phases of myocardial infarction (AMI). Care for AMI has changed dramatically in recent decades, with the introduction of coronary care units and treatments aimed at rapidly restoring coronary blood flow (Khush et al., 2005). Clinical practice guidelines provide clinicians with information on how to optimise treatments and studies have shown that greater compliance with guidelines improve health outcomes (e.g., Schiele et al., 2005; Eagle et al., 2005). However, some AMI patients do not receive recommended care, raising concerns over the quality of care in some countries (Brekke and Gjelsvik, 2009; Kotseva et al., 2009).
