Aims Patients with coronary heart disease (CHD) are at very high risk of recurrent events. A strategy to reduce excess risk might be to deliver structured secondary prevention programmes, but their efficacy has been mostly evaluated in the short term and in experimental settings. This is a retrospective case–control study aimed at assessing, in the real world, the efficacy of a secondary prevention programme in reducing long-term coronary event recurrences after coronary artery bypass surgery (CABG). Methods and results Programme participants (henceforth ‘cases’) were men and women aged Conclusion In a real-world setting, taking part in a structured longstanding secondary prevention programme, in addition to usual cardiology care, meaningfully lowers the risk of coronary recurrences.
