BACKGROUND/AIMS: Combination single-pill therapy can improve cost-effectiveness in a typical medical therapy. However, there is a little evidence about the efficacy and tolerability of combination single-pill antiplatelet therapy after percutaneous coronary intervention (PCI) with drug-eluting stents (DES). METHODS: From June to November 2012, in total, 142 patients who met the following criteria were enrolled: at least 18 years old; successful PCI with DES at least 3 months earlier; and regular medication of aspirin and clopidogrel with no side effects. After VerifyNow P2Y12 and aspirin assays, the combination single pill of aspirin and clopidogrel was given and laboratory tests were repeated 6 weeks later. RESULTS: At baseline, the incidence of aspirin resistance, defined as aspirin reaction unit (ARU) > or = 550, was 9.2%, that of clopidogrel resistance, defined as P2Y12 reaction unit (PRU) > or = 230, was 46.5%, and that of percent inhibition of PRU < 20% was 32.4%. At follow-up, the incidence of resistance by ARU value was 7.0%, 50.0% by PRU value, and 35.9% by percentage inhibition of PRU, respectively. The mean values of ARU (431.5 +/- 63.6 vs. 439.8 +/- 55.2; p = 0.216) and PRU (227.5 +/- 71.4 vs. 223.3 +/- 76.0; p = 0.350) were not significantly different before versus after antiplatelet-combination single-pill therapy. Five adverse events (3.5%) were observed during the study period. CONCLUSIONS: Combination single-pill antiplatelet therapy, which may reduce daily pill burden for patients after PCI with DES, demonstrated similar efficacy to separate dual-pill antiplatelet therapy.

BACKGROUND/AIMS: In the bare-metal stent era, routine follow-up coronary angiography (RFU CAG) was used to ensure stent patency. With the advent of drug-eluting stents (DESs) with better safety and efficacy profiles, RFU CAG has been performed less often. There are few data on the clinical impact of RFU CAG after second- or third-generation DES implantation in clinically stable patients with coronary artery disease; the aim of this study was to examine this issue. METHODS: We analyzed clinical outcomes retrospectively of 259 patients who were event-free at 12-month after stent implantation and did not undergo RFU CAG (clinical follow-up group) and 364 patients who were event-free prior to RFU CAG (angiographic follow-up group). Baseline characteristics were compared between the groups. RESULTS: The Kaplan-Meier estimated total survival and major adverse cardiac event (MACE)-free survival did not differ between the groups (p = 0.100 and p = 0.461, respectively). The cumulative MACE rate was also not different between the groups (hazard ratio, 0.85; 95% confidence interval, 0.35 to 2.02). In the angiographic follow-up group, 8.8% revascularization was seen at RFU CAG. CONCLUSIONS: RFU CAG did not affect long-term clinical outcome after second- or third-generation DES implantation in clinically stable patients.

Cardiotoxicity associated with 5-fluorouracil (FU) is an uncommon, but potentially lethal, condition. The case of an 83-year-old man with colon cancer who developed chest pain during 5-FU infusion is presented. The electrocardiogram (ECG) showed pronounced ST elevation in the lateral leads, and the chest pain was resolved after infusion of nitroglycerin. A coronary angiogram (CAG) revealed that the patient had significant atherosclerosis in the proximal left circumflex artery. Coronary artery spasm with fixed stenosis was considered, and a drug-eluting stent was implanted. After 8 hours, the patient complained of recurring chest pain, paralleled by ST elevation on the ECG. The chest pain subsided after administration of intravenous nitroglycerin followed by sublingual nifedipine. Repeated CAG showed patency of the previous stent. This case supports the vasospastic hypothesis of 5-FU cardiac toxicity, indicating that a calcium channel blocker may be effective in the prevention or treatment of 5-FU cardiotoxicity.
