Cancer has a non-negligible prevalence in patients with acute coronary syndrome undergoing percutaneous coronary intervention, with a major risk of cardiovascular events and bleedings. Moreover, these patients are often undertreated from clinical despite medical therapy seems to be protective. Registration:The BleeMACS project (NCT02466854).
Background-Very late stent thrombosis (VLST) was reported to occur even in patients with bare metal stent (BMS) implantation, although the annual incidence of VLST after BMS was much lower than that after drug-eluting stent implantation. Pathophysiologic mechanisms of VLST after BMS implantation remain largely unknown. . Evidence for fragments of atherosclerotic plaques, such as foamy macrophages, cholesterol crystals, and thin fibrous cap, was more commonly seen in patients with EST (23%) and VLST (31%), whereas these findings were rarely observed in patients with LST (10%). Atherosclerotic fragments were predominantly seen in patients who had EST within 7 days or VLST beyond 3 years. The aspirated thrombi harvested from patients with ST and those with ACS were histologically indistinguishable from each other. Eosinophils were very rarely observed. Plasma level of total cholesterol and triglyceride were significantly higher in VLST cases with atherosclerotic fragments as compared with those without. Conclusions-Fragments of atherosclerotic plaque were highly prevalent in patients with VLST beyond 3 years. Methods and Results-FromDisruption of in-stent neoatherosclerosis could play an important role in the pathogenesis of VLST of BMS occurring beyond 3 years after implantation.

The official journal of the Japan Atherosclerosis Society and the Asian Pacific Society of Atherosclerosis and Vascular Diseases Original Article Aim: Carotid plaque score (cPS) reflecting throughout the carotid artery plaque burden may be a better marker than carotid intima-media thickness (cIMT) is. We aimed to compare the prognostic utility of these measurements in patients with atherosclerotic cardiovascular disease (ASCVD). Methods: We retrospectively examined 2,035 Japanese patients with ASCVD who underwent carotid ultrasonography between January 2008 and December 2015 at Kanazawa University Hospital. Median follow-up period was 4 years. We used Cox models that adjusted for established risk factors of ASCVD, including age, gender, hypertension, diabetes, smoking, and serum lipids to assess the association of cIMT as well as cPS with major adverse cardiac events (MACE). MACE was defined as all-cause mortality or rehospitalization for a cardiovascular-related illness. Results: During follow-up, 243 participants experienced MACE. After adjustment for established risk factors, cPS was associated with MACE (hazard ratio [HR] 3.38 for top quintile vs. bottom quintile of cPS; 95% confidence interval [CI] 1.82-6.27; P trend 0.001), while cIMT was not (HR=0.88, P 0.57). Addition of the cPS to established risk factors significantly improved risk discrimination (C-index 0.726 vs. 0.746; P 0.017). Conclusion: These results suggest that cPS, rather than cIMT may be a better marker to identify increased risk for recurrence of MACE among patients with secondary prevention setting. Carotid intima-media thickness (cIMT) determined by less-invasive ultrasonography has been shown to be a surrogate marker for coronary atherosclerosis 4) , and increased cIMT has been shown to be associated with future cardiovascular events 5-7). On the other hand, carotid plaque score (cPS) reflecting throughout the carotid artery plaque burden may be better marker. Our previous study has shown that the carotid plaque score (cPS), reflecting the cumulative atherosclerotic burden of the carotid artery, is a more useful parameter to predict the atherosclerotic severity of the coronary artery than cIMT in patients with familial hypercholesterolemia (FH) 8) .

Care should be exercised with regard to selection of the electrodes, leads, paste, and lead system to obtain stable recordings during daily activities. The leads that are most likely to reflect ischemic changes are V5-like leads. In particular, lead CM5 is less affected by body movements and has a good detection rate for ischemic changes. 50 A 2-lead system is commonly used, and the AHA guidelines recommend a combination of leads that approximates leads V1 and V5. 51 For capturing ST elevation in patients with variant angina, vertical leads (II, III, and aVF) and approximations to lead V2 or V3 provide a high diagnostic rate. 52 Both circadian and diurnal (dayto-day) variations may exist in relation to the incidence and duration of myocardial ischemia and the extent of ST changes. However, it is difficult to evaluate the influence of diurnal variation based on 24-hour recording, which means that 48-hour recording is desirable for detecting myocardial ischemia and determining the response to treatment. ▋ 2.2.2 Criteria for ST-Segment Changes The diagnostic significance of persistent ST depression on Holter ECG is not high. Rather, detection and evaluation of transient ST-segment changes is more important. The criteria for ST depression are as follows: (1) horizontal or sagging depression of the ST segment by ≥0.1 mV; (2) reaching maximum ST depression after 1 min; and (3) ST depression of ≥0.1 mV lasting for ≥30-60 s compared with the baseline in a controlled state. 49,53-55 ST depression is measured at 0.08 s after the S or J point, and J-type ST depression is not judged to be ischemic ST depression. 52 When counting the number of ischemic episodes, the definition adopted is that each ischemic interval should last for at least 1 min. 56 The criterion for ST elevation is elevation of the ST segment by ≥0.1 mV lasting for ≥30-60 s in leads without Q waves. 49 In patients with chest pain ...
