Abstract

Abstract: Introduction: The impact of acute myocardial infarction (AMI) on the ability to pursue professional life is not well defined. Using a nationwide database, we aimed to describe the ability to return to work after AMI in Switzerland and identify factors associated therewith. Methods: AMI patients of working-age enrolled in the AMIS Plus registry between 01/2006 and 09/2020 with data on self-reported work status before and 12 months after AMI were included. Using the Kruskal-Wallis rank sum test or Fisher's exact test we compared patient characteristics between those who did not reduce work hours, those who reduced, and those no longer working 12 months after the AMI. Results: Of 4315 AMI patients (median (IQR) age 54 (49, 59)), 3204 (74.3%) did not reduce work, 592 (13.7%) reduced and 519 (12.0%) stopped working. Patients not reducing were youngest (median age (IQR)): 54y (49y, 58y), those who reduced: 56y (51y, 60y), those who stopped: 56y (51y, 61y), p<0.001) and more often men (no reduction: 90%, reduced: 80%, stopped: 82%, p<0.001). Patients who reduced showed worst cardiac function at AMI reflected in the highest rates of Killip class>2 (no reduction: 1.8%, reduced: 5.2%, stopped: 3.3%, p<0.001) and resuscitation before admission (no reduction: 4.1%, reduced: 6.9%, stopped: 4.0%, p=0.008). Patients who stopped work had the most comorbidities such as past AMI (no reduction: 8.6%, reduced: 10%, stopped: 13%, p=0.003), hypertension (no reduction: 45%, reduced: 50%, stopped: 54%, p<0.001), diabetes (no reduction: 10%, reduced: 13%, stopped: 16%, p<0.001) and cerebrovascular disease (no reduction: 0.8%, reduced: 1.2%, stopped: 2.3%, p=0.007). There was no significant difference for rehabilitation participation during follow up (no reduction: 84%, reduced: 86%, stopped: 84%, n.s. for all group comparisons). Multivariable regression showed that the reduction group had a higher proportion of women (OR 2.30; 95% CI 1.80–2.93 p<0.001) and were more likely to have a Killip class >2 at admission (OR 2.58; 95% CI 1.54–4.31 p<0.001) as compared to the no reduction group whereas the comparison between no reduction and work stop identified comorbidities (past MI (OR 1.46; 95% CI 1.07–1.94 p=0.016), diabetes (OR 1.59; 95% CI 1.21–2.09 p=0.001), cerebrovascular disease (OR 2.53; 95% CI 1.22–5.25 p=0.013)) and being female (OR 1.98; 95% CI 1.51–2.58 p<0.001) as major predictors for work stop. Conclusion: Our data showed that 1:7 had reduced and 1:8 stopped professional activity 1 year after AMI. Younger age, being male and lower rates of comorbidities such as a past AMI, hypertension, diabetes and cerebrovascular disease were important factors associated with returning to work after AMI. Work reduction was significantly related with worse cardiac function whereas work stop was more related with comorbidities. Funding Acknowledgement: Type of funding sources: None.
