BACKGROUND Coronary stent implantation is usually used to treat unstable angina to alleviate stenosis or occlusion,promoting blood flow restoration and alleviating symptoms such as myocardial ischemia.And postoperative cardiac rehabilitation is essential for enhancing recovery and prognosis.Nevertheless,conventional rehabilitation lacks specificity,particularly for elderly patients with multiple comorbidities and poor compliance,rendering it less effective.AIM To investigate the effects of systematic cardiac rehabilitation training in elderly patients with unstable angina following coronary stenting intervention.METHODS A retrospective enrollment was conducted comprising fifty-four elderly patients with unstable angina pectoris who underwent systematic cardiac rehabilitation training after receiving coronary intervention as the rehabilitation group,while fifty-three elderly patients who received basic nursing and rehabilitation guidance measures after coronary intervention were assigned to the control group.Differences in Seattle Angina Questionnaire scores,survival quality(SF-36)scores,cardiopulmonary exercise function assessment index,echocardiographic cardiac function index,and adverse cardiovascular events were compared between the two groups.RESULTS After intervention,the rehabilitation group observed greater VO2 Max,maximum metabolic equivalent,eft ventricular ejection fraction,left ventricular end-diastolic diameter and smaller left ventricular end-systolic diameter.And the rehabilitation group observed greater scores of physical activity limitation,stable angina pectoris,treatment satisfaction,and SF-36 score.The incidence of adverse cardiovascular events in the two groups,showed no significant difference.CONCLUSION Systematic cardiac rehabilitation following coronary stenting in elderly patients with unstable angina pectoris can enhance cardiac function recovery,consequently enhancing both quality of life and cardiopulmonary exercise tolerance. 展开更多

Objective:To explore the impact of a continuous precision nursing model on patients’Knowledge,Attitudes,and Practices(KAP)and cardiac function during the nursing process of patients undergoing percutaneous coronary angiography and stent implantation.Methods:Ninety patients who underwent percutaneous coronary angiography and stent implantation in our hospital from April 2022 to April 2023 were selected and randomly divided into the control group(45 cases),in which routine nursing support was carried out during the treatment process,and the observation group(45 cases),in which continuous precision nursing model was carried out during the treatment process.Comparisons were made between the two groups of patients on their KAP,cardiac function,and quality of life during recovery.Results:There was no difference in the left ventricular ejection fraction(LVEF),cardiac output(CO),and cardiac index(CI)levels before intervention.After the intervention,the levels of cardiac function in the observation group were higher than those of the control group(P<0.05).There was no difference in the Exercise of Self-Care Agency(ESCA)self-care ability scale scores before the intervention.After the intervention,the observation group had higher ESCA scores than the control group(P<0.05).Conclusion:Implementation of a continuous precision nursing model in the care of patients undergoing percutaneous coronary angiography and stent implantation improved the patient’s cardiac function,and KAP,and promoted recovery. 展开更多

BACKGROUND:To investigate the most appropriate dual antiplatelet therapy(DAPT)duration for patients with acute coronary syndrome(ACS)after drug-eluting stent(DES)implantation in the largest cardiovascular center of China.METHODS:We enrolled 5,187 consecutive patients with ACS who received DES from January to December 2013.Patients were divided into four groups based on DAPT duration:standard DAPT group(11-13 months,n=1,568)and prolonged DAPT groups(13-18 months[n=308],18-24 months[n=2,125],and>24 months[n=1,186]).Baseline characteristics and 5-year clinical outcomes were recorded.RESULTS:Baseline characteristics were similar across the four groups.Among the four groups,those with prolonged DAPT(18-24 months)had the lowest incidence of major adverse cardiovascular and cerebrovascular events(MACCEs)(14.1%vs.11.7%vs.9.6%vs.24.2%,P<0.001),all-cause death(4.8%vs.3.9%vs.2.1%vs.2.6%,P<0.001),cardiac death(3.1%vs.2.6%vs.1.4%vs.1.9%,P=0.004),and myocardial infarction(MI)(3.8%vs.4.2%vs.2.5%vs.5.8%,P<0.001).The incidence of bleeding was not different among the four groups(9.9%vs.9.4%vs.11.0%vs.9.4%,P=0.449).Cox multivariable analysis showed that prolonged DAPT(18-24 months)was an independent protective factor for MACCEs(hazard ratio[HR]0.802,95%confidence interval[CI]0.729-0.882,P<0.001),all-cause death(HR 0.660,95%CI 0.547-0.795,P<0.001),cardiac death(HR 0.663,95%CI 0.526-0.835,P<0.001),MI(HR 0.796,95%CI 0.662-0.957,P=0.015),and target vessel revascularization(HR 0.867,95%CI 0.755-0.996,P=0.044).Subgroup analysis for high bleeding risk showed that prolonged DAPT remained an independent protective factor for all-cause death and MACCEs.CONCLUSION:For patients with ACS after DES,appropriately prolonging the DAPT duration may be associated with a reduced risk of adverse ischemic events without increasing the bleeding risk. 展开更多

Acute kidney injury following percutaneous coronary intervention (PCI) is associated with a worse outcome. However, the risk factors and outcomes of acute kidney injury (AKI) in patients after intracoronary stent implantation are still unknown. A retrospective case control study was done in 325 patients who underwent intracoronary stent implantation from January 2010 to March 2011 at the Drum Tower Hospital of Nanjing University School of Medicine. Those were excluded from the study if they had incomplete clinical data. The patients were divided into a normal group and a AKI group according to the standard of post-operation day 7 to identify AKI. The parameters of the patients included: 1) pre-operative ones: age, gender, hypertension, diabetes mellitus, cerebrovascular disease, left ventricular insufficiency, peripheral angiopathy, creatinine, urea nitrogen, estimated glomerular filtration rate (eGFR), hyperuricemia, proteinuria, emergency operation, hydration, medications (ACEI/ARBs, statins); 2) intraoperative ones: dose of contrast media, operative time, hypotension; and 3) postoperative one: hypotension. The parameters were analyzed with univariate analysis and multivariate logistical regression analysis. Of the 325 patients, 51(15.7%) developed AKI. Hospital day and in-hospital mortality were increased significantly in the AKI-group. Univariate analysis showed that age, pre-operative parameters (left ventricular insufficiency, peripheral angiopathy, creatinine, urea nitrogen, estimated glomerular filtration rate, hyperuricemia, proteinuria, hydration), emergency operation, intraoperative parameters (operative time, hypotension) and postoperative hypotension were significantly different. However, multivariate logistic regression analysis revealed that increased age (OR=0.253, 95%CI=0.088-0.727), pre-operative proteinuria (OR=5.351, 95%CI=2.128-13.459), pre-operative left ventricular insufficiency (OR=8.704, 95%CI=3.170-23.898), eGFR〈60 ml/min/1.73 m2 (OR=6.677, 95%CI=1.167-38.193), prolonged operative time, intraoperative hypotension (OR=25.245, 95%CI=1.001-1.034) were independent risk factors ofAKl. AKI is a common complication and associated with ominous outcome following intracoronary stent implantation. Increased age, pre-operative proteinuria, pre-operative left ventricular insufficiency, pre-operative low estimated glomerular filtration rate, prolonged operative time, intraoperative hypotension were the significant risk factors ofAKl. 展开更多

Objective: To study the effects of comprehensive nursing interventions on sexual functions in young and middle-aged patients with coronary stent implantation. Methods: 96 cases of coronary stent implantation were randomly divided into control group and intervention group (experimental group) with each group of 48 cases. The control group received the routine nursing measures after the coronary stent implantation and the experimental group was treated by the comprehensive nursing interventions such as psychological nursing, education of sexual knowledge, playing the full enthusiasm of spouse and appropriate exercise therapy on basis of the routine nursing measures. The two groups were given the questionnaire of brief male sexual function questionnaire (BSFI), Chinese patients with premature ejaculation sexual function score (C-ISFPE) and the international index of erectile function (IIEF-5). The scores of BSFI, C-ISFPE and IIEF-5 were compared between the two groups. Results: There were 29 cases who were satisfied with sexual life on the whole (≤1), 26 cases with different degrees of premature ejaculation symptoms and 21 cases with erectile dysfunctions, which were respectively 27.08%, 30.2% and 21.87% of the total number. The scores of BSFI, C-ISFPE and IIEF-5 inthe experimental group were significantly increased after the interventions (P P IIEF-5 scores in the two groups were significantly different 展开更多

Objective We used intravascular ultrasound (IVUS) to assess incidence, predictors, morphology, and angiographic findings of edge dissections and intramural hematomas after drug-eluting stent (DES) implantation. Methods We studied 887 patients with 1 045 non-in-stent restenosis lesions in 977 native arteries undergoing DES implantation with IVUS imaging, and compared the dissected stent end to the non-dissected stent end. Results Eighty-two dissections were detected; 51.2% (42/82) involved the proximal and 48.8% (40/82) the distal stent edge. When compared to the non-dissected stent end, residual plaque area [(8.0±4.3) mm2 vs (5.2±3.0) mm2, P【0.01], plaque burden [(52±12)% vs (36±15)%, P【0.01], plaque eccentricity (8.4±5.5 vs 4.0±3.4, P【0.01), and stent edge symmetry (1.17±0.11 vs 1.14±0.08, P=0.02) were larger; plaque burden≥50% was more frequent (62% vs 17%, P【0.01) and calcium deposits (52.5% vs 35.6%, P=0.03) more common; and the lumen/stent area (0.86±0.16 vs 1.02±0.18, P【0.01) was smaller in the stent dissected end. Independent predictors of stent edge dissection were residual plaque eccentricity (OR=1.3, P【0.01) and residual plaque burden≥50% (OR=7.3, P【0.01). Intramural hematomas occurred in 34.1% (28/82) of dissections.Independent predictors of intramural hematomas were plaque eccentricity (OR=1.4, P=0.005), plaque burden≥50% (OR=7.1, P=0.02), and mean lumen diameter to stent diameter ratio (OR=0.37, P=0.04).Concluslon IVUS identified edge dissections after 9.4% of DES implantations. Residual plaque eccentricity and significant plaque burden predicted coronary stent edge dissections. Dissections in less diseased reference segments with an arc of normal vessel wall (greater plaque eccentricity) more often evolved into an intramural hematoma. 展开更多

Biodegradable stents made of magnesium(Mg)and its alloys have been developed to minimize persistent inflammation or in-stent restenosis,which are the main problems for permanent stents.However,their rapid corrosion behavior under physiological conditions leads to poor vascular compatibility and premature structural failure,which remains an important unsolved clinical problem.Herein,we demonstrate a new strategy for solving this problem by combining poly(ether imide)(PEI)coating and subsequent tantalum(Ta)ion implantation.The PEI coating covers the whole surface of the Mg stent uniformly via a spray coating technique and provides Mg with superior corrosion resistance and stable sirolimus-carrying ability.Ta ion implantation is conducted by a sputtering-based plasma immersion ion implantation technique only onto the luminal surface of the PEI-coated Mg stent.Its extremely short processing time(<30 s)permits preservation of the PEI coating’s corrosion protection ability and sirolimus loading characteristics.In addition,a Ta-implanted skin layer that forms on the topmost surface of the PEI coating plays an effective role in not only preventing a rapid release of sirolimus from the surface but also improving the PEI coating’s surface hydrophilicity.Based on in vitro cellular response and blood compatibility tests,Ta ion implantation leads to the improvement of endothelial cell adhesion/proliferation and suppression of platelet adhesion/activation regardless of sirolimus loading.These results indicate that the combination of PEI coating and Ta ion implantation has significant innovative potential to provide excellent vascular compatibility and prevent in-stent restenosis and thrombosis. 展开更多

It has been reported that up to 12% of patients underwent non-cardiac surgery or invasive procedures within the first year after the coronary stent implantation. Premature dis- continuation of antiplatelet therapy is associated with a sig- nificant increase in mortality and major adverse cardiac events, in particular, stent thrombosis. Thus, postpone- ment of elective surgery is advocated during the first year after the coronary stent implantation. 展开更多

Stent implantation in acute myocardial infarction(AMI)has been shown to improvethe acute angiographic outcomes.So far few data on long-term angiographic follow-up are avallble.Methods:We studied 130 consecutive patients(mean age 58±11,24 women)betweenOctober 1993 and October 1997,in whom coronary stonts were implanted afterunsuccessful percutaneous transluminal coronary angioplasty (PTCA)in AMI.Quantitative coronary angiography(QCA)was performed and residual stenosis wasmesuremesured for all patients immediately and for 74 patients at a mean of 6 months afterthat procedure.Results:The infarct related artery was the left anterior dascending in 60(46%)pts,the circumflex in 15(12%)and the right coronary artery in 55(42%).At baseline,72(55%)pts had a totally occluded artery(TLMI0)and 11(8%)TIMI 1 flow. Eight(6%) pte were given aboiximab(ReoPro) or thrombolyais to deal with acute slantthrombosis during the intervention.Immedately after stent implantation,angiographicsuccess(TLMI 3)was obtained in 113(87%)pts,TLMI2 in 14 (11%)and TLMI 1 intwo (2%). Only three pts had residual stonosis(≥50% stenosis)immediately aftertreatment.Except the patients who had coronary artery bypass grafting(CABG)ordied coronary angiographic follow-up was performed in 74(70%)pts at a mean of 6months following the intervention(Table).Conclusion:Rescue stent implantation after failed PTCA in AMI may improve initialangiographic results,but we found a higher restenosis-rate and reintervention-rate inthe long-term run as compared with selectiv stent implantation. 展开更多

The clinical benefit of coronary-artery steating performed inconjunction with coronary angioplasty is limited by the risk of thromboticocclusion of the stant as well as hemorrhagic and vascular complications ofintensive anticoaguistion.We analysed complications of three patientscaused by improper antithrombotic therapy after coronary artery stanting.Method and Result:Case 1,male,52 years old.The diagnosis is old myocardial infarction(OMI),unstable angina pectoris(UAP).Gianturco-Roubin stent was successfullyimplanted into right coronary artery(RCA).Balloon angioplasty wasperformed in left circumflex artary(LCX).Angiography showed optimal resultafter the procedure.The patient bad acute inferior myocardial infarction onthe same day,and died from ventricular fibrillation on the third day afterthe stenting.Case 2,male,53 years old.The diagnosis is UAP.Two Gianturco-RoubinStents were implanted into left anterior descending artery(LAD)and RCArespectively,angioplasty was done in LCX On the tenth day atfer theprocedure,bloody urine happened.By reducing warfarin dosage be bloodyurine disappeared.Case 3.female.71 years old.the diagnosis is acute anterior myocardialinfarction,UAP.Multilink stent was implanted into LAD,balloon dilatationwas done in RCA.On the day of the stenting,groin regional bleeding andshock happendod.Afterwards.acute anterior,Supralataral MI and acute heartfailure happended.Finally the patient was discharged.DiscussionRecently the success rate of the stent implantation reach at 95%.However,the main complications are stent thrombosis as well as bleeding,vascular access complicalions caused by intensive antithrombotic agent.Inthese three patients,the death of the first case is due to acute stentthrombosis resulted from insufficient antithrombotic therapy.The bloodyurine of second case is caused by too much intensive anticoagulation.Thecomplications of the third case is due to too much intensive antithrombosisat beginning and insufficient antithrombosis at latter.The antithrombosisafter stenting should be monitored by ACT,CT or PTT The antipisteletherapy can largely reduce the stent thrombosis and the incidence of theleeding. 展开更多

Purpose: To analyze the application of percutaneous transluminal angioplasty and stenting in acute deep venous thrombosis of lower extremities. Methods: 70 patients were divided into two groups according to the presence or absence of percutaneous transluminal angioplasty and stenting. Results: The mean circumferential diameter difference between the affected limbs and the healthy limbs and the knees at 15 cm was statistically significant. The cure rate and effective rate of the research group were higher than those of the control group (P<0.05). Conclusion: Percutaneous transluminal angioplasty and stenting are of high value in acute lower extremity deep venous thrombosis. 展开更多
