Özet
Objectives: We aimed to identify the predictors of angiographically visible distal embolization (AVDE) during primary percutaneous coronary intervention (p-PCI) as well as to assess its impact on short- and long-term clinical outcomes in patients with acute ST-segment elevation myocardial infarction (STEMI). Study design: We retrospectively enrolled 2007 patients with STEMI who underwent p-PCI. We assessed the clinical and angiographic characteristics of patients in order to identify the predictors of AVDE and compared the outcomes of patients with and without AVDE during p-PCI. Results: Distal embolization developed in 135 (6.7%) patients. Age (for each 10- year increase, Odds Ratio (OR) 1.34, 95% Confidence Interval (CI) 1.16-1.52, p<0.001), treatment of right coronary artery (OR 2.52, 95% CI 1.30-4.87, p=0.034), repeated balloon dilatation (OR 1.84, 95% CI 1.16-2.94, p=0.009), cut-off occlusion pattern (OR 2.17, 95% CI 1.38-3.42, p=0.001), lesion length >15 mm (OR 1.67, 95% CI 1.09-2.58, p=0.019), and reference vessel diameter >3.5 mm (OR 5.08, 95% CI 3.32-7.65, p<0.001) were independent predictors of AVDE. In-hospital (8.1% vs. 3.8%, p=0.014) and one-month (10.8% vs. 4.9%, p=0.004) all-cause mortality rates were higher in patients with AVDE. At the long-term follow-up (median: 42 months), both all-cause (21.5% vs. 10.4%, p<0.001) and cardiac mortality rates (18.4% vs. 8.0%, p<0.001) were higher in patients with AVDE. Conclusion: AVDE is associated with worse clinical outcome at both the short- and long-term follow-up of STEMI patients treated early with p-PCI. © 2013 Turkish Society of Cardiology.
