Objectives:The study assessed the relationship between atherogenic index of plasma(AIP)and the rapid progression of coronary non-target lesions.Methods:A total of 1 247 patients with coronary artery disease who underwent two coronary angiography examinations at Fuwai Hospital,Chinese Academy of Medical Sciences between January 2010 and September 2014 were enrolled in this retrospective study.The AIP is defined as the base 10 logarithm of the ratio of the concentrations of triglyceride to high-density lipoprotein cholesterol.Patients were divided into the high AIP group(n=623)and the low AIP group(n=624)based on the median value of AIP.Lesion rapid progression is defined as an increase of more than 10%in the lumen stenosis of the lesion with a stenosis rate of more than 50%,or an increase of more than 30%in the lumen stenosis rate of the lesion with a stenosis rate of less than 50%,or a progression to total occlusion within 2 years.Results:Median AIP was 0.39(0.23-0.56)in this patient cohort.Rapid progression of non-target lesions occurred in 65(5.21%),including 42(6.74%)in the high AIP group.The Kaplan-Meier curve showed that the cumulative incidence of rapid progression of non-target lesions was higher in the high AIP group than in the low AIP group(HR=1.751,95%CI:1.053-2.912,log-rank P=0.028).In univariate cox analysis,the AIP and high AIP correlated with rapid progression of non-target lesions.After multivariate adjustment,AIP was an independent risk factor for rapid progression of non-target lesions(adjusted HR=2.731,95%CI:1.090-6.844,P=0.032).Conclusions:AIP is an independent risk factor for rapid progression of non-target lesions.AIP should be considered as a biomarker for estimating the risk of cardiovascular disease,along with other traditional risk factors.

Objective:Investigate the impact of calcification on the long-term outcomes of patients with coronary chronic total occlusion (CTO) after percutaneous coronary intervention (PCI).Methods:A retrospective cohort study was conducted. Patients who underwent PCI and had at least one CTO lesion at Fuwai Hospital between January 2010 and December 2013 were consecutively enrolled. Calcification was evaluated by coronary angiography, and patients were divided into two groups: moderate/severe calcification group and non/mild calcification group. Clinical follow-up was completed up to 5 years. Incidence of PCI-related complications and immediate procedural outcomes were compared between two groups, and the primary endpoint was the target lesion failure (TLF) at 5 years after PCI. Clinical follow-up endpoint events were analyzed using Kaplan-Meier survival analysis with log-rank test, and Cox multivariate regression model was used to evaluate the relationship between calcification and TLF.Results:The study included 2 659 CTO patients with an age of (57.2±10.5) years, of whom 442 (16.6%) were female, and among whom 13.5% (360/2 659) had moderate/severe calcification. Compared with the non/mild calcification group, the moderate/severe calcification group had a higher incidence of PCI-related complications (43.2% (156/361) vs. 32.5% (772/2 374), P<0.001) and procedural failure (34.3% (124/361) vs. 24.3% (577/2 374), P<0.001). Additionally, the moderate/severe calcification group showed a higher risk of the primary endpoint event (TLF) during the 5-year follow-up (19.8% vs. 15.3%, log-rank P=0.028). Higher incidence of cardiac death was observed in moderate/severe calcification group (5.7% vs. 2.7%, log-rank P=0.003). Cox multivariate regression analysis revealed that moderate/severe calcified plaques remained an independent risk factor for 5-year TLF after CTO-PCI ( HR=1.34, 95% CI: 1.01-1.79, P=0.043). Conclusion:Compared with CTO patients with non/mild calcification, those with moderate/severe calcification have higher procedural failure and complication rates, as well as poorer long-term prognosis, mainly due to an increase in cardiac death.

Objectives:To analyze the efficacy and safety of drug coated balloon for coronary de novo lesions in real world. Methods:We enrolled consecutive patients with coronary de novo lesions treated with drug coated balloons from January 2020 to June 2021 in Fuwai Hospital.The baseline data,procedure data and in-hospital cardiac events were collected through case query.All patients were followed up by clinical visit or telephone call.Major adverse cardiac events(MACE)were defined as the composite of the cardiac death,acute myocardial infarction,target lesion revascularization.According to the diameter of the blood vessels,the patients are divided into the large vessel lesion group(vessel diameter≥2.75 mm,n=337),and the small vessel lesion group(vessel diameter<2.75 mm,n=575). Results:There were 940 coronary de novo lesions in 912 patients.A total of 974 drug balloons were used,average diameter was(2.6±0.8)mm,average length was(21.0±6.0)mm,average pressure was(10.0±3.8)atm.Among the 940 primary coronary artery lesions,343 lesions had a diameter≥2.75 mm,and 597 lesions had a diameter<2.75 mm.During hospitalization,two patients with acute ST-segment elevation myocardial infarction died of cardiac rupture after emergency coronary interventional treatment,acute vessel closure because of coronary hematoma occurred in 1 patient and bailout drug-eluting stent was used in this patient,five patients received salvage stent treatment due to type C dissection immediately after drug coated balloon treatment.During follow-up,Target lesion revascularization(TLR)occurred in 15(1.6%)patients(including coronary artery bypass grafting in 1 patient).Nonfatal acute myocardial infarction occurred in 1 patient,cardiac death occurred in 1 patient,2 patients died of cerebral hemorrhage,1 patient died of cerebral infarction,MACE rate was 1.9%(17/912).MACE rate during follow-up was similar between large vessels group and small vessels group(1.8%vs.1.9%,P>0.05). Conclusions:Our study indicates that drug coated balloon for coronary de novo lesion is safe and effective.There is no difference of MACE rate between large vessel group and small vessel group.

Objective: To investigate the efficacy of bare metal stent for treating focal coronary artery aneurysm complicating with severe stenosisin single coronary artery. Methods: This retrospective analysis was performed in 7 patients who were diagnosed as local coronary artery aneurysm complicating with severe stenosis(≥70%) in single coronary artery and treated with bare metal stent during the period from December 2012 to June 2015 in Fuwai Hospital. All 7 patients were male with age of (62±11) years old. During the interventional operation, the narrow parts were pre-expanded,and all patients received bare metal stents implantation to cover aneurysms.The clinical and imaging data of patients immediately post procedure and at postoperative follow-up were collected to evaluate the clinical efficacy. Results: There were 5 cases of left anterior descending aneurysms and 2 cases of right coronary artery aneurysms. The diameter of aneurysm was (5.21±1.28)mm, and the length was (13.71±3.88)mm. There was intracranial vortex in coronary arteriography immediately after intervention.Proximalstenosis of coronary artery aneurysm was disappeared,and the distal blood flow was TIMI class 3.There were no signs of aortic dissection and thrombus formation.During 6(6 16) months follow-up, the aneurysms were disappeared,and there were no major adverse cardiovascular events which including myocardial ischemia, acute myocardial infarction, revascularization,bleeding,and death for all patients. Conclusion Initial experience shows that double-layer bare metal stents implantation for patients with localized coronary artery aneurysm complicating with severe stenosis in single vessel is safe and effective.
