Assessing inflammation in Chinese subjects with subtypes of heart failure: an observational study of the Chinese PLA Hospital Heart Failure Registry

Background Inflammation is an important element of the pathophysiological process of heart failure (HF) and is correlated with subtypes of HF. The association between multiple biomarkers of inflammation and HF subtypes in Chinese subjects remains unclear. This study aimed to compare the differences in inflammation biomarkers among Chinese patients with different subtypes of HF who have been identified to date. Methods We included 413 consecutive patients with HF,including 262 with preserved ejection fraction (HFpEF),55 with middle-ranged ejection fraction (HFmrEF) and 96 with reduced ejection fraction (HFrEF). Ten inflammation biomarkers were analyzed and compared according to the HF subtypes. One hundred contemporary non-HF subjects were also recruited as the control group. Moreover,the correlations between the inflammatory biomarkers and left ventricular ejection fraction of the HF subtypes were assessed. Results The mean age of the HF patients was 65.0 ± 12.0 years,65.8% were male. Distinct subtypes of HF demonstrated different inflammation biomarker panels. IL-6,PTX-3,ANGPTL-4 and TNF-α were correlated with HFrEF;IL-1β and PTX-3 were correlated with HFmrEF;and IL-1β and IL-6 were correlated with HFpEF. The multivariable logistic regression showed that IL-1β[relative ratio (RR)= 1.08,95% CI: 1.02–1.15,P = 0.010],IL-6 (RR = 1.03,95% CI: 1.01–1.06,P = 0.016),PTX-3 (RR = 1.31,95% CI: 1.11–1.55,P = 0.001),and ANGPTL-4 (RR = 1.05,95% CI: 1.02–1.07,P < 0.001) were independently associated with HF,while IL-6 (RR = 1.03,95% CI: 1.01–1.04,P = 0.019),PTX-3 (RR = 1.23,95% CI: 1.06–1.43,P = 0.007),and ANGPTL-4 (RR = 1.03,95% CI: 1.01–1.06,P = 0.005) were independently associated with the HF subtype. Conclusions Diverse inflammation biomarkers have multifaceted presentations according to the subtype of HF,which may illustrate the diverse mechanisms of inflammation in Chinese HF patients. IL-6,PTX-3,and ANGPTL-4 were independent inflammation factors associated with HFrEF and HF.

Treatment of severely calcified coronary artery disease by intravascular lithotripsy primary outcomes and 180-day followup from the Chinese SOLSTICE Trial

OBJECTIVE To assess the safety and effectiveness of intravascular lithotripsy(IVL)treatment for de novo coronary lesion involving severely calcified vessels in a Chinese population.METHODS The Clinical Trial of the ShOckwave Coronary IVL System Used to Treat CalcIfied Coronary ArtEries(SOLSTICE)was a prospective,single-arm,multicentre trial.According to the inclusion criteria,patients with severely calcified lesions were enrolled in the study.IVL was used to perform calcium modification prior to stent implantation.The primary safety endpoint was freedom from major adverse cardiac events(MACEs)at 30 days.The primary effectiveness endpoint was procedural success,defined as successful stent delivery with residual stenosis<50% by core lab assessment without in-hospital MACEs.The morphological changes of calcium modification were assessed by optical coherence tomography(OCT)before and after IVL treatment.RESULTS Patients(n=20)were enrolled at three sites in China.Severe calcification by core lab assessment was present in all lesions,with a mean calcium angle and thickness of 300±51°and 0.99±0.12 mm(by OCT),respectively.The 30-day MACE rate was 5%.Both primary safety and effectiveness endpoints were achieved in 95% of patients.The final in-stent diameter stenosis was 13.1%±5.7% with no patient had a residual stenosis<50%after stenting.No serious angiographic complications(severe dissection grade D or worse,perforation,abrupt closure,slow flow/no-reflow)observed at any time during the procedure.OCT imaging demonstrated visible multiplane calcium fracture in 80% of lesions with a mean stent expansion of 95.62%±13.33% at the site of maximum calcification and minimum stent area(MSA)of 5.34±1.64 mm^(2).CONCLUSIONS The initial coronary IVL experience for Chinese operators resulted in high procedural success and low angiographic complications consistent with prior IVL studies,reflecting the relative ease of use of IVL technology.

Successful opening in-stent chronic total occlusion lesion of coronary artery by excimer laser coronary angioplasty

In percutaneous coronary intervention (PCI), chronic total occlusion (CTO) coronary artery disease still remains difficult to treat. One of the reasons for the failure is the hard of the CTO lesions that balloon is difficult to pass through or expand. Previous methods to deal with CTO lesions that cannot be passed by balloon, include selecting reinforced catheter (such as 5 in 6 guiding catheter, Guidzilla catheter, or Tornus microcatheter), guidewire extrusion or rotary grinding technology. In recent years, excimer laser coronary angioplasty (ELCA) has been gradually applied to CTO lesions. Using inert halide as the laser medium, ELCA emits a 308 nm high-intensity unidirectional light wave with absorption depth of only 50 μmL, resulting in less thermal effect and less damage to non-target lesions. In this paper, we will describe a successful PCI case of an in-stent CTO lesion using ELCA with long term coronary angiography follow-up.

A world's first attempt of mixed-reality system guided inferior vena cava filter implantation under remote guidance of 5G communication

Deep vein thrombosis(DVT)is a manifestation of venous thromboembolism,which can result from long-term bed and lead to pulmonary embolism(PE),stroke,mesenteric artery embolis,etc.Patients after surgery without bed-off activity may prone to thrombosis,but traditional anticoagulant therapy is a contraindication for them because of high risk of postoperative hemorrhage.Inferior vena cava filter(IVCF)implantation is the most effective method to intercept thrombosis from lower limb and to prevent PE.However,radiation and contrast agent limit its application.Our team have successfully performed an IVCF implantation guided by a mixed-reality(MR)system,[1]which is a chance for critically ill patients to allow the IVCF implantation exposed under no Xray and require no contrast agent.5G can help remote holographic projection images between distant range,meeting the needs of experts to guide the operation of critically ill patients.We describe a case of weak woman after neurosurgery who can not tolerate traditional interventional surgery to prevent DVT from falling off.We performed a mixed-reality system guided IVCF implantation under remote guidance of 5G communication.

Intracoronary arterial retrograde thrombolysis with percutaneous coronary intervention: a novel use of thrombolytic to treat acute ST-segment elevation myocardial infarction

Background Clearance of coronary arterial thrombosis is necessary in patients with acute ST-segment elevation myocardial infarction (STEMI) undergoing urgent percutaneous coronary intervention (PCI). There is currently no highly-recommended method of thrombus removal during interventional procedures. We describe a new method for opening culprit vessels to treat STEMI: intracoronary arterial retrograde thrombolysis (ICART) with PCI. Methods & Results Eight patients underwent ICART. The guidewire was advanced to the distal coronary artery through the occlusion lesion. Then, we inserted a microcatheter into the distal end of the occluded coronary artery over the guidewire. Urokinase (5–10 wu) mixed with contrast agents was slowly injected into the occluded section of the coronary artery through the microcatheter. The intracoronary thrombus gradually dissolved in 3–17 min, and the effect of thrombolysis was visible in real time. Stents were then implanted according to the characteristics of the recanalized culprit lesion to achieve full revascularization. One patient experienced premature ventricular contraction during vascular revascularization, and no malignant arrhythmias were seen in any patient. No reflow or slow flow was not observed post PCI. Thrombolysis in myocardial infarction flow grade and myocardial blush grade post-primary PCI was 3 in all eight patients. No patients experienced bleeding or stroke. Conclusions ICART was accurate and effective for treating intracoronary thrombi in patients with STEMI in this preliminary study. ICART was an effective, feasible, and simple approach to the management of STEMI, and no intraprocedural complications occurred in any of the patients. ICART may be a breakthrough in the treatment of acute STEMI.

Objective To observe the effect of Danhong injection(DI)in patients with acute ST-segment elevation myocardial infarction(STEMI)at a high risk of no-reflow(NR)during primary percutaneous coronary intervention(PCI).Methods Patients were placed in a DI group and control group.The DI group was given DI and the control group was given physiologic saline.The administration lasted 4 to 6 days in both groups after PCI.Cardiac magnetic resonance(CMR)was carried out during the perioperative period(7±2 days).The primary endpoint of the study was myocardial infarct size(IS)imaged on delayed-enhancement CMR.The secondary endpoint was major adverse cardiac events observed 6 months after PCI.Results In total,160 high-risk NR patients were enrolled,and 110 patients completed the CMR examination.According to postoperative CMR,the Myocardial Salvage Index and left ventricular ejection fraction were higher in the DI group(0.57±0.13 vs.0.48±0.17,P<0.01;49.3%±6.9%vs.46.2%±7.7%,P=0.03,respectively),whereas the IS was lower(19.7%±5.6%vs.22.2%±6.5%,P=0.04),compared with that in the control group.These differences were observed to be significant.After 6 months,the prevalence of major adverse cardiac events in the DI group decreased compared with that in the control group,but the differences were not observed to be significant(P>0.05).Conclusion The application of DI can reduce the myocardial infarct size in STEMI patients at a high risk of NR during primary PCI.
