RESUMO
BACKGROUND: The aim of this study is to evaluate clinical outcomes after percutaneous coronary intervention (PCI) in patients with cancer.MethodsâandâResults:Cancer screening was recommended before PCI in consecutive 1,303 patients who underwent their first PCI. By using cancer screening, cancer was diagnosed in 29 patients (2.2%). In total, 185 patients had present or a history of cancer. Patients with cancer more often suffered from non-cardiac death than those without (4.4% vs. 1.5%, P=0.006), and patients with cancer requiring ongoing therapy (n=18) more often suffered from major bleeding compared with those with recently (≤12 months) diagnosed cancer who do not have ongoing therapy (n=59) (16.7% vs. 3.4%, P=0.049). During the 1-year follow up, 25 patients (2.0%) were diagnosed as having cancer, in which 48.0% of bleeding events led to a cancer diagnosis. Patients with high bleeding risk according to the Academic Research Consortium for high bleeding risk (ARC-HBR) were associated with a greater 1-year major bleeding risk than those without high bleeding risk in patients with (7.9% vs. 0.0%, P=0.02) and without cancer (7.1% vs. 2.5%, P<0.001), respectively. CONCLUSIONS: Cancer was diagnosed in 2.2% of 1,303 unselected patients before PCI by cancer screening and in 2.0% within 1-year after PCI. Cancer was associated with a greater risk of non-cardiac death, whereas ongoing active cancer was associated with greater risk of major bleeding. ARC-HBR criteria successfully identified high-bleeding risk patients, irrespective of the presence or absence of cancer.

BACKGROUND: Percutaneous coronary intervention for heavily calcified lesions requires rotational atherectomy (RA). Long-term clinical outcomes after drug-eluting stent (DES) implantation following (RA) for heavily calcified lesions remain unclear. We assessed 5-year clinical outcomes after DES implantation following RA.MethodsâandâResults:Between March 2006 and September 2011, 219 consecutive patients with 219 lesions treated with DES following RA, were retrospectively enrolled. The cumulative 5-year incidence of target-lesion revascularization (TLR) and definite stent thrombosis (ST) were assessed. The cumulative incidence of TLR within (≤) the first year was 18.6%. Late TLR beyond (>) 1 year continued to occur at 1.9% per year without a decrease in the rate (5-year incidence, 26.0%). The cumulative incidence of definite ST at 30 days, 1 and 5 years was 0.9%, 2.3% and 2.9%, respectively. The annual rate of definite ST beyond 1 year was 0.15%. On multivariate analysis, the significant predictor of TLR within 1 year was use of first-generation DES (hazard ratio [HR], 2.09; 95% CI: 1.10-4.03, P=0.02) and that of TLR beyond 1 year was hemodialysis (HR, 3.29; 95% CI: 1.06-10.55, P=0.04). CONCLUSIONS: Late TLR beyond 1 year continued to occur up to 5 years at a constant annual incidence, whereas very late ST was rare. Careful long-term clinical follow-up is continually needed in patients who have already received DES following RA for heavily calcified lesions.

A 40-year-old man was referred to our hospital for the treatment of severe calcified coronary lesions of right coronary artery due to Kawasaki disease. He had a past history of early stent thrombosis after drug-eluting stent implantation for acute myocardial infarction at the left anterior descending artery, regardless of continued dual antiplatelet therapy and no stent malapposition and underexpansion. We performed rotational atherectomy and plain balloon angioplasty with optical frequency domain imaging guidance, and obtained an excellent initial result without stent implantation, which was maintained during the 1-year follow-up.
