Abstract Background Anemia is a common risk factor for post-percutaneous coronary intervention (PCI) adverse events; however, data on its association with in-stent restenosis (ISR) is limited. Methods 538 patients who underwent PCI between January 2017 and September 2019 and follow-up angiography 9–12 months after the initial PCI were enrolled in this study. Baseline clinical and procedural characteristics were compared between the ISR and non-ISR groups, and independent predictors of ISR were determined using propensity score matching. Results The incidence of anemia was 53.5% in patients with ISR and 19.0% in those without ISR. Univariable logistic regression analyses showed that anemia (OR, 4.283; 95% CI, 1.949–9.410; P < 0.001), diabetes mellitus (OR, 2.588; 95% CI, 1.176–5.696; P = 0.018), chronic kidney disease (OR, 3.058; 95% CI, 1.289–7.252; P = 0.011), multiple stenting (OR, 2.592; 95% CI, 1.205–5.573; P = 0.015), bifurcation lesion (OR, 2.669; 95% CI, 1.236–5.763; P = 0.012), and calcification (OR, 3.529; 95% CI, 1.131–11.014; P = 0.030) were closely associated with ISR. Low-density lipoprotein cholesterol (LDL-c) levels and stent diameter were also significantly linked to ISR, as was anemia (P = 0.009) after propensity score matching. Conclusion Anemia is closely associated with post-PCI ISR, and patients with lower hemoglobin levels are at a higher risk of ISR.

Abstract Background Anemia is a well-recognized risk factor for adverse events after percutaneous coronary intervention (PCI), but data regarding the association between anemia and in-stent restenosis (ISR) remain limited.Methods A total of 538 patients who underwent PCI between January 2018 and September 2019 and performed follow-up angiography 9–12 months after the initial PCI was enrolled in the study. Baseline clinical and procedural characteristics were compared between ISR and non-ISR group. Multivariate logistic regression analysis was employed to determine the independent predictors of ISR.Results The incidence of anemia in patients with ISR was 53.5% and 19.0% in the non-ISR group, which was significantly different (P ༜0.001). The rate of diabetes, chronic kidney disease (CKD), bifurcation lesion and calcification was significantly higher in ISR group. In addition, low-density lipoprotein cholesterol (LDL-c), multiple stenting and stent diameter were also significantly related with ISR. After multivariate logistic analysis, anemia (odds ratio [OR], 2.786; 95% confidence interval [CI], 1.091 to 7.115; P = 0.032) together with LDL-c (OR, 1.682; 95% CI, 1.145 to 2.469; P = 0.008), diabetes (OR, 3.582; 95% CI, 1.406 to 9.125; P = 0.007), CKD (OR, 2.841; 95% CI, 1.006 to 8.027; P = 0.049), multiple stenting (OR, 2.823; 95% CI, 1.184 to 6.731; P = 0.019), and stent diameter (OR, 2.778; 95% CI, 1.069 to 7.194; P = 0.036) were closely associated with ISR.Conclusion Anemia is closely associated with ISR after PCI, patients with lower hemoglobin have a higher risk of ISR.

Abstract Background As an initial treatment strategy, percutaneous coronary intervention (PCI) for coronary chronic total occlusion (CTO) did not show mid-term survival benefits compared with optimal medical therapy (OMT). Purpose To compare 10-year clinical outcomes between OMT and PCI in CTO patients. Methods Between March 2003 and February 2012, 2,024 patients with CTO were enrolled in a single center registry and followed for about 10 years. We excluded CTO patients who underwent coronary artery bypass grafting, and classified patients into the OMT group (n=664) or PCI group (n=883) according to initial treatment strategy. Propensity-score matching was performed to minimize potential selection bias. The primary outcome was cardiac death. Results In the PCI group, 699 patients (79.2%) underwent successful revascularization. Clinical and angiographic characteristics revealed more comorbidities and more complex lesions in the OMT group than in the PCI group. At 10 years, the PCI group had lower risks of cardiac death (10.4% versus 22.3%; HR 0.43; 95% CI 0.32 to 0.57; p&lt;0.001) than the OMT group. After the propensity-score matching analyses, the PCI group had lower risks of cardiac death (13.6% versus 20.8%; HR 0.62; 95% CI 0.44 to 0.88; p=0.007), acute myocardial infarction (6.3% versus 11.2%; HR 0.55; 95% CI 0.34 to 0.91; p=0.02), any revascularization (23.9% versus 32.2%; HR 0.67; 95% CI 0.51 to 0.88; p=0.004) than the OMT group. The beneficial effects of CTO PCI were consistent across various subgroups (all p-values for interaction: non-significant). Conclusions As an initial treatment strategy, PCI reduced late cardiac death compared with OMT in CTO patients.

Összefoglaló. Bevezetés: A szívinfarktust megelőző revascularisatiós beavatkozások prognosztikai jelentőségével kapcsolatban kevés elemzés ismeretes, hazai adatokat eddig nem közöltek. Célkitűzés: A szerzők a Nemzeti Szívinfarktus Regiszter adatait felhasználva elemezték a koszorúér-revascularisatiós szívműtétet (CABG) túlélt betegek prognózisát heveny szívinfarktusban. Módszer: Az adatbázisban 2014. 01. 01. és 2017. 12. 31. között 55 599 beteg klinikai és kezelési adatait rögzítették: 23 437 betegnél (42,2%) ST-elevációval járó infarktus (STEMI), 32 162 betegnél (57,8%) ST-elevációval nem járó infarktus (NSTEMI) miatt került sor a kórházi kezelésre. Vizsgáltuk a CABG után fellépő infarktus miatt kezelt betegek klinikai adatait és prognózisát, amelyeket azon betegek adataival hasonlítottunk össze, akiknél nem szerepelt szívműtét a kórelőzményben (kontrollcsoport). Eredmények: A betegek többsége mindkét infarktustípusban férfi volt (62%, illetve 59%). Az indexinfarktust megelőzően a betegek 5,33%-ánál (n = 2965) történt CABG, amely az NSTEMI-betegeknél volt gyakoribb (n = 2357; 7,3%). A CABG-csoportba tartozó betegek idősebbek voltak, esetükben több társbetegséget (magas vérnyomás, diabetes mellitus, perifériás érbetegség) rögzítettek. Az indexinfarktus esetén a katéteres koszorúér-intervenció a kontrollcsoport STEMI-betegeiben gyakoribb volt a CABG-csoporthoz viszonyítva (84% vs. 71%). Az utánkövetés 12 hónapja során a betegek 4,7–12,2%-ában újabb infarktus, 13,7–17,3%-ában újabb katéteres koszorúér-intervenció történt. Az utánkövetés alatt a CABG-csoportban magasabbnak találtuk a halálozást. A halálozást befolyásoló tényezők hatásának korrigálására Cox-féle regressziós analízist, illetve ’propensity score matching’ módszert alkalmaztunk. Mindkét módszerrel történt elemzés azt mutatta, hogy a kórelőzményben szereplő koszorúér-revascularisatiós műtét nem befolyásolta a túlélést. Amennyiben a beteg kórelőzményében szerepelt a koszorúérműtét, az indexinfarktus nagyobb eséllyel volt NSTEMI, mint STEMI (HR: 1,612; CI 1,464–1,774; p<0,001). Következtetés: A kórelőzményben szereplő koszorúér-revascularisatiós műtét nem befolyásolta a szívinfarktus miatt kezelt betegek életkilátásait. Orv Hetil. 2021; 162(5): 177–184. Summary. Introduction: Little analysis is known about the prognostic significance of revascularization interventions before myocardial infarction; no domestic data have been reported so far. Method: The authors use data from the Hungarian Myocardial Infarction Registry to analyze the prognosis of patients with acute myocardial infarction who had previous coronary artery bypass grafting (CABG). Between 01. 01. 2014. and 31. 12. 2017, 55 599 patients were recorded in the Registry: 23 437 patients (42.2%) had ST-elevation infarction (STEMI) and 31 162 patients (57.8%) had non-ST-elevation infarction (NSTEMI). The clinical data and prognosis of patients treated for infarction after CABG were compared with those of patients without a CABG history. Results: The majority of patients were male (59% and 60%, respectively). Prior to index infarction, CABG occurred in 5.33% of patients (n = 2965), which was more common in NSTEMI (n = 2357; 7.3%). The CABG patients were older and had more comorbidities (hypertension, diabetes mellitus, peripheral vascular disease). For index infarction, percutaneous coronary intervention was more common in STEMI patients in the control group compared to CABG (84% vs. 71%). At 12 months of follow-up, 4.7–12.2% of patients had reinfarction, and 13.7–17.3% had another percutaneous coronary intervention. During the full follow-up, the CABG group had higher mortality. Cox regression analysis and propensity score matching were used to correct for the effect of other factors influencing mortality. Both analyses showed CABG did not affect survival. In the CABG group, the index infarction was more likely to be NSTEMI than STEMI (HR: 1.612; CI 1.464–1.774; p<0.001). Conclusion: The history of CABG does not affect the life expectancy of patients treated for an acute myocardial infarction. Orv Hetil. 2021; 162(5): 177–184.

In Stent Restenosis

Currently, percutaneous coronary intervention is an important treatment for coronary heart disease. However, the in-stent restenosis rate is still approximately 10–30% after stenting. Nickel ions from the stent are considered to be associated with in-stent restenosis. Therefore, in the present study, we quantitatively evaluated in-stent restenosis after implanting the novel high-nitrogen low-nickel coronary stent (HNS) and studied the mechanism underlying the reduction in in-stent restenosis by using ELISA and Western blot. The in vivo results showed that the HNS could significantly reduce neointima formation and inflammation as compared to SUS316L stents (316L) at 180 days after implantation in porcine coronary arteries and that vascular endothelial growth factor-A expression in porcine coronary arteries after HNS implantation also decreased. The in vitro results showed that, in the case of the HNS, human umbilical vein endothelial cell (HUVEC) proliferation was lower and lesser IL-6 release was noted from HUVECs at one and three days after culture than in the 316L group. Furthermore, p-STAT3 expression in HUVECs on the HNS surface was downregulated after culture for seven days. Thus, we conclude that the HNS could be a promising alternative coronary stent for percutaneous coronary intervention.

The Impact

Abstract The impact of pre-existing depression on mortality in individuals with established coronary artery disease (CAD) remains unclear. We evaluate the clinical implications of pre-existing depression in patients who underwent percutaneous coronary intervention (PCI). Based on National Health Insurance claims data in Korea, patients without a known history of CAD who underwent PCI between 2013 and 2017 were enrolled. The study population was divided into patients with angina (n=50,256) or acute myocardial infarction (AMI; n=40,049). The primary endpoint, defined as all-cause death, was compared between the non-depression and depression groups using propensity score matching analysis. After propensity score matching, there were 4,262 and 2,346 matched pairs of patients with angina and AMI, respectively. During the follow-up period, there was no significant difference in the incidence of all-cause death in the angina (hazard ratio [HR] of depression, 1.013; 95% confidence interval [CI]: 0.893-1.151) and AMI (HR, 0.991; 95% CI: 0.865-1.136) groups. However, angina patients less than 65 years of age with depression had higher all-cause mortality (HR, 1.769; 95% CI: 1.240-2.525). In Korean patients undergoing PCI, pre-existing depression is not associated with poorer clinical outcomes. However, in younger patients with angina, depression is associated with higher all-cause mortality.
