- Background: The role of systemic atherosclerosis in myocardial infarction (MI) patients is not fully understood. We investigated the incremental prognostic value of coronary and systemic atherosclerosis after acute MI by estimating extra-cardiac artery disease (ECAD) and extent of coronary atherosclerosis.Methods and results: The study included 544 prospective MI patients undergoing coronary angiography. For all patients, the longitudinal coronary atherosclerotic extent, expressed as Sullivan extent score (SES) was calculated. In addition, the patients underwent non-invasive screening for ECAD in the carotid, aortic, renal and lower limb. SES was found to be associated with ECAD independent of baseline clinical parameters [adjusted odds ratio (OR) 1.04 95% confidence interval (CI) 1.02-1.06, P < 0.001]. Extensive systemic atherosclerosis, defined as the combination of extensive coronary disease (SES >= 17) and ECAD, was associated with higher risk for all-cause mortality compared to limited systemic atherosclerosis (SES < 17 and no ECAD) (hazard ratio [HR] 2.9 95% CI 1.9-4.5, P < 0.001, adjusted for Global Registry of Acute Coronary Events risk score parameters 1.8, 95% CI 1.1-3.0, P = 0.019). The risk for the composite endpoint of cardiovascular death or hospitalization was significantly higher in patients with extensive systemic atherosclerosis compared to patients with limited systemic atherosclerosis (HR 3.1, 95% CI 2.1-4.7, P < 0.001, adjusted HR 1.9, 95% CI 1.2-3.1, P < 0.004).Conclusions: Visual estimation of the longitudinal coronary atherosclerotic extent at the time of MI predicts ECAD. Coexistence of extensive coronary disease and ECAD defines a group with particularly poor prognosis after MI.

- Background and aims: In patients with coronary artery disease (CAD), clinically overt extracoronary artery diseases (ECADs), including claudication or previous strokes, are associated with poor outcomes. Subclinical ECADs detected by screening are common among such patients. We aimed to evaluate the prognostic impact of subclinical versus symptomatic ECADs in patients with acute myocardial infarction (AMI).Methods: In a prospective observational study, 654 consecutive patients diagnosed with AMI underwent ankle brachial index (ABI) measurements and ultrasonographic screening of the carotid arteries and abdominal aorta. Clinical ECADs were defined as prior strokes, claudication, or extracoronary artery intervention. Subclinical ECADs were defined as the absence of a clinical ECAD in combination with an ABI <= 0.9 or >1.4, carotid artery stenosis, or an abdominal aortic aneurysm.Results: At baseline, subclinical and clinical ECADs were prevalent in 21.6% and 14.4% of the patients, respectively. Patients with ECADs received evidence-based medication more often at admission but similar medications at discharge compared with patients without ECADs. During a median follow-up of 5.2 years, 166 patients experienced endpoints of hospitalization for AMI, heart failure, stroke, or cardiovascular death. With ECAD-free cases as reference and after adjustment for risk factors, a clinical ECAD (hazard ratio [HR] 2.10, 95% confidence interval [CI] 1.34-3.27, p = 0.001), but not a subclinical ECAD (HR 1.35, 95% CI 0.89-2.05, p = 0.164), was significantly associated with worse outcomes.Conclusions: Despite receiving similar evidence-based medication at discharge, patients with clinical ECAD, but not patients with a subclinical ECAD, had worse long-term prognosis than patients without an ECAD after AMI.
