Lower extremity peripheral artery disease (PAD) has been proposed as a 'coronary heart disease (CHD) risk equivalent'. We aimed to examine whether PAD confers similar risk for mortality as incident myocardial infarction (MI) and whether risk differs by gender.
Using nationwide Danish administrative registries (2000-2008), we identified patients aged =40 years with incident PAD (PAD only, n?=?35,628), incident PAD with a history of MI (PAD?+?MI, n?=?7029), and incident MI alone (MI alone, n?=?71,115).
Patients with PAD only tended to be younger, female, and have less comorbidity than the other groups. During follow up (median 1051 d, IQR 384-1938), we found that MI-alone patients had greater risk of adverse outcomes in the acute setting (first 90 d); however, the PAD-only and PAD?+?MI groups had higher long-term mortality at 7 years than those with MI alone (47.8 and 60.4 vs. 36.4%, respectively; p?
