Cardiovascular diseases(CVDs)are a leading factor driving mortality worldwide.Iron,an essential trace mineral,is important in numerous biological processes,and its role in CVDs has raised broad discussion for decades.Iron-mediated cell death,namely ferroptosis,has attracted much attention due to its critical role in cardiomyocyte damage and CVDs.Furthermore,ferritinophagy is the upstream mechanism that induces ferroptosis,and is closely related to CVDs.This review aims to delineate the processes and mechanisms of ferroptosis and ferritinophagy,and the regulatory pathways and molecular targets involved in ferritinophagy,and to determine their roles in CVDs.Furthermore,we discuss the possibility of targeting ferritinophagy-induced ferroptosis modulators for treating CVDs.Collectively,this review offers some new insights into the pathology of CVDs and identifies possible therapeutic targets.

OBJECTIVE: To analyze the incidence, clinical characteristics and prognosis of sepsis-related liver injury(SELI). METHODS: The data of septic patients in the department of Critical Care Medicine of the First Affiliated Hospital of China Medical University from January 2013 to December 2014 were collected and the basic information, infection site, emergency operation and residence were recorded. Also, the duration of ICU, the first 24 h APACHE II and SOFA score, mechanical ventilation, MODS, nutritional support, serum total bilirubin and aminotransferase, the duration of liver dysfunction and the duration of liver dysfunction during ICU stay were recorded. Rank sum test was used to compare age, APACHE II score, SOFA score, length of stay in ICU, duration of mechanical ventilation; Chi square test was used to compare the patient's source, type of operation, whether MODS, and nutritional support; The logistic regression analysis was used to analyze the related factors of death. RESULTS: A total of 341 septic patients with sepsis were included in the study, including 96 patients with septis-related liver dysfunction. The main manifestations were elevated transaminase in 17 cases(17.71%), elevated bilirubin in 31 cases(32.29%), elevated bilirubin and transaminase in 48 cases(50%) and liver injury in 66 cases(68.75%) of sepsic patients occurred within 1-3 days of ICU 3.22 days(1-40 days). The morbidity and mortality of MODS in sepsis-related liver injury patients were 70.83% and 33.33%. Statistically differences in APACHE II scores, SOFA scores, mechanical ventilation duration, and MODS in patients with different prognosis were revealed. Further logistic regression analysis showed that sepsis with MODS was an independent risk factor for death. There were statistical difference in duration of symptoms, duration of ICU stay and prognosis. CONCLUSION: The morbidity of SELI is high, mostly in the early stage of sepsis, men are more prone to the disease. The abdominal cavity is the most common site of infection. High APACHEII score, prolonged mechanical ventilation and MODS are independent risk factors for SELI.

BACKGROUNDThere are limited data on the efficacy of drug-eluting stents (DES) for treatment of chronic total occlusions (CTO). The aim of the study was to evaluate the long-term clinical outcomes of DES implantation for CTO compared with bare-metal stent (BMS) implantation.

METHODSBetween June 1995 and December 2006, a total of 1184 patients with successful recanalization of at least one de novo CTO lesion were consecutively registered, including 660 (55.7%) who underwent DES and 524 (44.3%) who underwent BMS implantation. All patients were followed up for up to 5 years for occurrence of major adverse cardiac events (MACE). Long-term survival rates were estimated with the Kaplan-Meier method.

RESULTSBaseline clinical and angiographic characteristics were comparable between the two groups except that patients in the DES group received longer dual antiplatelet therapy ((7.4 +/- 2.5) months vs (1.7 +/- 0.8) months, P < 0.001). Average follow-up periods were (4.7 +/- 0.89) and (3.2 +/- 1.3) years for the BMS and DES groups, respectively. There was no significant difference in 5-year survival rates between the two groups (90.3% for DES group vs 89.6% for BMS group, Log-rank P = 0.38), but the 5-year target vessel revascularization (TVR)-free survival rate in the DES group was significantly higher than that in the BMS group (81.6% vs 73.5%, Log-rank P < 0.001). The cumulative MACE-free survival in the DES group was also significantly higher than that in the BMS group (80.6% vs 71.5%, Log-rank P < 0.001). The rates of re-admission caused by cardiovascular disease (27.0% vs 37.8%, P < 0.001) and the need for bypass surgery were significantly lower in the DES group (1.5% vs 3.4%, P < 0.05). By multivariable analysis, DES implantation could significantly lower the long-term MACE risk of PCI for CTO patients (HR: 0.492; 95% CI 0.396 - 0.656, P < 0.001). Left ventricular ejection fraction < 50% and elderly (> or = 65 years) were identified as independent predictors of long-term MACE during follow-up.

CONCLUSIONThis study demonstrates the long-term (up to 5 years) efficacy of DES for treatment of CTO, which is superior to BMS implantation in reducing the rates of TVR and MACE, as well as the need of re-admission and bypass surgery.

OBJECTIVETo assess the technique and outcomes of coronary intervention treatment for patients with chronic total occlusion (CTO) lesions.

METHODSRetrospectively analyzed the data from 1148 patients with CTO who were treated by percutaneous coronary intervention (PCI) between June 1993 and December 2004. There were 1494 CTO lesions in 1458 vessels with a mean occlusion time of (49.1 +/- 31.6) months. A total of 1499 stents were implanted to those target lesions.

RESULTSTotal success rates of patients and lesions were 90.2% (1036/1148) and 88.2% (1317/1494), respectively. The success rate of PCI was declined in CTO lesions with long occlusion time, stump missing, bridging collaterals and >or= 15 mm in length (P < 0.05). Operative failures were occurred in 112 patients. Guide wire and balloon failed to pass through the occlusion accounted for 82.1% and 17.9% of all failures respectively. No death was occurred during operation, but 2 patients suffered from acute stent thrombosis and other 9 patients suffered from acute or later pericardium perforation. After procedure, there were 3 patients died and 3 patients suffered from subacute stent thrombosis during in-hospital period. The total in-hospital major adverse cardiac events rate was 0.6% (7/1148). The angina-free survival rate was 87.1% at discharge.

CONCLUSIONIn an experienced heart center, it is possible to obtain a relatively high success rate of PCI and ideal clinical outcomes in patients with CTO coronary lesions.

High mobility group box-1 protein (HMGB1), which is a nuclear protein, participates in chromatin architecture and transcriptional regulation. When released from cells, HMGB1 also plays a well-established role as a pro-inflammatory mediator during innate immune responses to injury. In the initial stage of injury, there is a release of large quantities of early pro-inflammatory mediators to initiate or perpetuate immune responses against pathogens, but this pro-inflammatory period is transient, and it is followed by a prolonged period of immune suppression. At present, several lines of evidences have suggested that HMGB1 is a late cytokine provoking delayed endotoxin morbidity, which may enhance the production of early proinflammatory mediators, and it can contribute potently to the activation of different immune cells and play a role in the development of host cell-mediated immunity. The biology of HMGB1 has been extensively studied as a pro-inflammatory cytokine of systemic inflammation, however, this review will attempt to provide a summary of the effects of HMGB1 on different immune cells and its regulatory mechanism in acute insults.

BACKGROUNDData on the efficacy and safety of drug-eluting stent (DES) for treatment of multiple coronary chronic total occlusion (CTO) lesions are scanty. The aim of the present study was to compare the long-term outcomes of DES versus bare metal stent (BMS) implantation for multiple coronary CTO lesions.

METHODSWe analyzed 188 patients who underwent coronary stenting for at least two de novo CTO lesions in our center from November 2000 to November 2006. Among them, 118 patients (62.8%) received DES and 70 patients (37.2%) received BMS implantation after the recanalization for CTO lesions. All patients were followed up for up to 5 years for the occurrence of major adverse cardiac events (MACE). Long-term survival rates were estimated with the Kaplan-Meier method.

RESULTSThere were no significant differences in baseline clinical characteristics and procedural success rate between DES group and BMS group. Compared with the BMS group, the DES group showed a significantly higher rate of long CTO (> or = 15 mm) (62.0% vs. 50.6%, P = 0.023). The number of stents per lesion (1.39 +/- 0.71 vs. 1.17 +/- 0.66, P = 0.007) and the mean length of stents in the DES group were also higher than those in the BMS group ((40.8 +/- 11.4) mm vs. (23.4 +/- 8.7) mm, P < 0.001). But the mean diameter of stents in the DES group was smaller than that in the BMS group ((3.1 +/- 0.2) mm vs. (3.3 +/- 0.5) mm, P < 0.001). Average follow-up time was 4.8 +/- 0.7 (1.5 - 5.0) years in the BMS group and 4.3 +/- 0.5 (1.3 - 5.0) years in the DES group. Both the 5-year cumulative survival rates and the target vessel revascularization (TVR)-free survival rates of the DES group were significantly higher than those in the BMS group (83.1% vs. 72.9%, Log-rank P = 0.044; 77.1% vs. 62.9%, Log-rank P = 0.009). The cumulative MACE-free survival rates in the DES group were significantly higher than those in the BMS group (71.2% vs. 51.4%, Log-rank P = 0.001). Multivariable Cox regression analysis demonstrated that DES implantation for multiple CTO lesions could significantly reduce the long-term MACE risk after percutaneous coronary intervention (PCI) (HR: 0.436; 95%CI 0.327 - 0.665, P < 0.001). Age over 65 years (HR: 2.018; 95%CI 1.491 - 3.127, P < 0.001) and left ventricular ejection fraction < 50% (HR: 1.494; 95%CI 1.125 - 2.376, P < 0.001) were identified as the independent predictors of long-term MACE.

CONCLUSIONThis study demonstrates the long-term (up to 5 years) efficacy and safety of DES for treatment of multiple coronary CTO lesions, and its superiority compared to BMS in reducing the rates of TVR and MACE.

BACKGROUNDCoronary chronic total occlusion (CTO) remains one of the most challenging lesion subsets in interventional cardiology, even with the development of medical device and operator expertise. This study was conducted to examine the relationship between lesion characteristics and procedural success and the incidence of in-hospital major adverse cardiac events (MACE) after percutaneous coronary intervention (PCI) for CTO.

METHODSClinical and coronary angiographic data of 1263 patients with CTO who underwent PCI between June 1995 and December 2005 in Shenyang General Hospital of PLA were retrospectively analyzed.

RESULTSThere were 1625 CTO lesions located in 1596 vessels with a mean occlusion time of 48.9 months. A total of 1647 coronary stents were implanted to the target lesions. The overall patient and lesion success rates were 90.8% (1147/1263) and 88.9% (1445/1625), respectively. The success rate of PCI was declined with long duration of occlusion, abrupt missing stump, bridging collaterals > or = 15 mm in occluded length, moderate to severe calcification or tortuosity and ostial or distal location of CTO lesions (P < 0.05). Procedural failure occurred in 116 patients, caused by impossibility of guide-wire (81.0%) or balloon (19.0%) to pass through the occlusion. There was no death during procedure, but 2 patients suffered from acute stent thrombosis and other 9 patients had acute or late pericardial perforation. Those complications were all successfully treated. After procedure, 3 patients died, 4 experienced urgent target vessel revascularization because of subacute stent thrombosis and 1 underwent coronary bypass graft surgery due to coronary fistula during in-hospital period. The overall in-hospital MACE rate was 0.6% (8/1263). Drug-eluting stents were used in 198 patients without in-hospital MACE.

CONCLUSIONSIn an experienced heart center, it is possible to obtain a relatively high success rate of PCI and favorable clinical outcomes for patients with coronary CTO lesions.

BACKGROUNDRapid recanalization of infarct-related artery (IRA) has become the major target during primary percutaneous coronary intervention (PCI) for patients with ST-elevation myocardial infarction (MI), but strategy for treatment of non-IRA lesions in this setting remains unclear. This study aimed to compare long-term effects between PCI for IRA only and that for both IRA and non-IRA in ST-elevation MI patients with multi-vessel disease.

METHODSA total of 242 eligible patients with ST-elevation MI and at least two diseased coronary arteries (luminal narrowing > or = 70%) undergoing primary PCI were included. Of them, 149 patients underwent primary PCI for IRA only (group 1), and 93 received primary PCI for IRA followed by elective PCI for non-IRA 7 to 15 days after acute myocardial infarction (AMI) (group 2). Drug-eluting stents (DESs) were deployed in more than 90% of the patients.

RESULTSThe two groups did not differ with respect to baseline clinical and angiographic characteristics. No significant differences were observed in 12-month clinical follow-up results regarding major adverse cardiac events (11.5% vs 15.1%, P > 0.05) and target lesion revascularization (8.1% vs 7.6%, P > 0.05) between the two groups. However, patients in group 1 had higher rates of recurrent angina (10.1% vs 2.1%, P < 0.05) and depressed left ventricular ejection fraction evaluated by echocardiography (0.56 +/- 0.22 vs 0.63 +/- 0.25, P < 0.05).

CONCLUSIONWith the use of DESs, complete revascularization with elective PCI for non-IRA after primary PCI may exert a beneficial effect on long-term symptomatology and left ventricular function in patients with ST-elevation MI and multi-vessel disease.
