OBJECTIVES: We sought to determine the prevalence, predictors, and clinical impact of target lesion calcification in patients undergoing percutaneous coronary intervention (PCI) with newer generation drug-eluting stents (DES) and devices. BACKGROUND: Coronary calcification is independently associated with adverse outcomes following PCI. While newer DES and contemporary devices are considered safer and more efficacious, their influence on outcomes following PCI of heavily calcified lesions is unknown. METHODS: We performed a retrospective analysis of a large, multiethnic cohort of patients undergoing PCI with new generation DES at an academic center between 2009 and 2013. Coronary calcification was qualitatively assessed as none/mild, moderate, or severe. Independent demographic, clinical, and anatomic predictors of moderate/severe calcification were identified using logistic regression. Associations between coronary calcification and 1-year MACE (death, myocardial infarction, or target vessel revascularization) were examined using Cox modeling. RESULTS: Compared to patients with none/mild (n = 10,180; 82.0%), those with moderate (n = 1,271; 10.0%) or severe (n = 994; 8.0%) calcification were older, more often Caucasian, had more complex target lesions, and worse renal function. The strongest demographic, clinical, and anatomic correlates of moderate/severe calcification were age, Caucasian race, renal dysfunction, lesion length, and left main location. Unadjusted MACE rates among those with none/mild, moderate, and severe calcification were 8.3, 14.6, and 17.8%, respectively (P < 0.001). After multivariable adjustment, the hazard ratio (95% CI) for MACE associated with moderate or severe coronary calcification was 1.63. CONCLUSIONS: Target lesion calcification remains independently associated with adverse outcomes in patients treated with newer generation DES and modern devices.
