The impact of peripheral artery disease on major adverse cardiovascular events following myocardial infarction

• Aims: Peripheral artery disease (PAD) constitute a high-risk with adverse clinical outcomes. We aimed to investigate the cardiovascular outcomes following myocardial infarction (MI). Methods and results: This nationwide, Danish register-based follow-up study includes all patients experiencing an MI between 2000 and 2017. Patients with and without PAD were compared. Multivariable logistic regression was used to derive relative risks of 1-year major adverse cardiovascular events (MACE; all-cause mortality, reinfarction, stroke or heart failure). Individual components, cardiovascular mortality, and bleeding, standardized to age, sex and comorbidity distributions of all patients were assessed. MI patients with PAD (n = 5083, 2.9%) were older and more comorbid compared to patients without PAD (n = 174,673). After standardization, PAD was associated with higher 1-year relative risks of MACE (RR 1.21 [95% CI 1.17;1.25]), all-cause (RR 1.29 [95% CI 1.24;1.35]) and cardiovascular mortality (RR 1.3 [95% CI 1.24;1.36]), reinfarction (RR 1.17 [95% CI 1.11;1.22]), stroke (RR 1.12 [95% CI 0.92;1.32]), heart failure (RR 1.22 [95% CI 1.12;1.32]), and bleeding episodes (RR 1.25 [95% CI 1.04,1.46]). Similar results were seen in 30-day survivors after adjustment for antithrombotic post-discharge medication for MACE (RR 1.25 [95% CI 1.20,1.31]), all-cause mortality (RR 1.47 [95% CI 1.37,1.57], cardiovascular mortality (RR 1.49 [95% CI 1.37,1.61]), reinfarction (RR 1.17 [95% CI 1.08,1.12]) and heart failure (RR 1.22 [95% CI 1.12,1.32]). Conclusion: Comparing to patients without PAD, patients with PAD had increased 1-year relative risk of MACE, all-cause mortality, reinfarction, stroke, heart failure, cardiovascular mortality and bleeding following MI. The low prevalence of PAD is suggestive of considerable under-diagnosing.
