Objective: To investigate the impact of combined use and timing of arterial-venous extracorporeal membrane oxygenation (VA-ECMO) with intra-aortic balloon pump (IABP) on the prognosis of patients with acute myocardial infarction complicated with cardiogenic shock (AMICS). Methods: This was a prospective cohort study, patients with acute myocardial infarction and cardiogenic shock who received VA-ECMO support from the Heart Center of Lanzhou University First Hospital from March 2019 to March 2022 in the registration database of the Chinese Society for Extracorporeal Life Support were enrolled. According to combination with IABP and time point, patients were divided into VA-ECMO alone group, VA-ECMO+IABP concurrent group and VA-ECMO+IABP non-concurrent group. Data from 3 groups of patients were collected, including the demographic characteristics, risk factors, ECG and echocardiographic examination results, critical illness characteristics, coronary intervention results, VA-ECMO related parameters and complications were compared among the three groups. The primary clinical endpoint was all-cause death, and the safety indicators of mechanical circulatory support included a decrease in hemoglobin greater than 50 g/L, gastrointestinal bleeding, bacteremia, lower extremity ischemia, lower extremity thrombosis, acute kidney injury, pulmonary edema and stroke. Kaplan-Meier survival curves were used to analyze the survival outcomes of patients within 30 days of follow-up. Using VA-ECMO+IABP concurrent group as reference, multivariate Cox regression model was used to evaluate the effect of the combination of VA-ECMO+IABP at different time points on the prognosis of AMICS patients within 30 days. Results: The study included 68 AMICS patients who were supported by VA-ECMO, average age was (59.8±10.8) years, there were 12 female patients (17.6%), 19 cases were in VA-ECMO alone group, 34 cases in VA-ECMO+IABP concurrent group and 15 cases in VA-ECMO+IABP non-concurrent group. The success rate of ECMO weaning in the VA-ECMO+IABP concurrent group was significantly higher than that in the VA-ECMO alone group and the VA-ECMO+IABP non-concurrent group (all P<0.05). Compared with the ECMO+IABP non-concurrent group, the other two groups had shorter ECMO support time, lower rates of acute kidney injury complications (all P<0.05), and lower rates of pulmonary edema complications in the ECMO alone group (P<0.05). In-hospital survival rate was significantly higher in the VA-ECMO+IABP concurrent group (28 patients (82.4%)) than in the VA-ECMO alone group (9 patients) and VA-ECMO+IABP non-concurrent group (7 patients) (all P<0.05). The survival rate up to 30 days of follow-up was also significantly higher surviving patients within were in the ECMO+IABP concurrent group (26 cases) than in VA-ECMO alone group (9 patients) and VA-ECMO+IABP non-concurrent group (4 patients) (all P<0.05). Multivariate Cox regression analysis showed that compared with the concurrent use of VA-ECMO+IABP, the use of VA-ECMO alone and non-concurrent use of VA-ECMO+IABP were associated with increased 30-day mortality in AMICS patients (HR=2.801, P=0.036; HR=2.985, P=0.033, respectively). Conclusions: When VA-ECMO is indicated for AMICS patients, combined use with IABP at the same time can improve the ECMO weaning rate, in-hospital survival and survival at 30 days post discharge, and which does not increase additional complications.

Objective: To investigate the effect of gender on the efficacy of intra-aortic balloon pump(IABP) applied in patients with cardiogenic shock complicated by acute myocardial infarction(AMI). Methods: A total of 209 patients diagnosed as cardiogenic shock complicated by AMI admitted in Fuwai Hospital from June 2012 to May 2018 were enrolled in our study. We collected the data from medical records and investigated their clinical manifestation and laboratory examination and IABP support, as well as 28-day (from diagnosis of cardiogenic shock) mortality retrospectively. Kaplan-Meier survival analysis was used to compare the 28-day survival rates of patients of different genders/with or without IABP treatment. Adjustment for age, systolic blood pressure, ST segment elevation myocardial infarction, dual antiplatelet, coma, APACHEⅡ score and SAPSⅡ score, Cox regression analysis was used to detect the affect of IABP treatment on the risk of all-cause mortality in different crowd, and using Z test to evaluate the modification effect of gender on IABP treatment efficacy. Results: A total of 209 patients were included in this study, with 148 males (80 (54.05%) cases received IABP support) and 61 females (22 (36.06%) cases received IABP support). A total of 102 patients received IABP treatment. The 28-day survival rate of male patients was higher than that of females (39.2% (58/148) vs. 26.2% (16/61), Log-rank P=0.034). The 28-day survival rate of patients receiving IABP was significantly higher than that of non-IABP groups (46.1% (47/102) vs. 25.2% (27/107), Log-rank P=0.001 7). Among female patients, there was no statistically significant difference in 28-day survival rate between those who received IABP and those who did not receive IABP (P=0.889). While in male patients, the 28-day survival rate of those who received IABP was higher than that of those who did not receive IABP (51.2% (41/80) vs. 25.0% (17/68), P=0.001). The survival rate of male patients treated with IABP was higher than that of male patients who did not receive IABP, female patients who did not receive IABP and female patients who received IABP (all P<0.05). After multiple regression analysis and adjustment of confounding factors, it was found that IABP implantation can significantly reduce the 28-day mortality risk in male patients (HR=0.44, 95%CI 0.25-0.77 P=0.004). While it had no inpact on the death risk in female patients(P= 0.401). The impact of IABP implantation in patients of different genders was significantly different (Z=-2.32, P=0.020). Conclusion: In AMI patients complicating cardiogenic shock, there is a gender difference in the impact of IABP implantation on the 28-day mortality risk, and protective effects are seen only in men.

BACKGROUND: There are few reports of peri-operative application of intra-aortic balloon pumping (IABP) in patients with coronary artery disease (CAD) and different grades of left ventricular dysfunction. This study aimed to analyze the early outcomes of peri-operative application of IABP in coronary artery bypass grafting (CABG) among patients with CAD and left ventricular dysfunction, and to provide a clinical basis for the peri-operative use of IABP. METHODS: A retrospective analysis of 612 patients who received CABG in the General Hospital of People's Liberation Army between May 1995 and June 2014. Patients were assigned to an IABP or non-IABP group according to their treatments. Logistic regression analysis was performed to investigate the influence of peri-operative IABP implantation on in-hospital mortality. Further subgroup analysis was performed on patients with severe (ejection fraction [EF] ≤ 35%) and mild (EF = 36%-50%) left ventricular dysfunction. RESULTS: Out of 612 included subjects, 78 belonged to the IABP group (12.7%) and 534 to the non-IABP group. Pre-operative left ventricular EF (LVEF) and EuroSCOREII predicted mortality was higher in the IABP group compared with the non-IABP group (P < 0.001 in both cases), yet the two did not differ significantly in terms of post-operative in-hospital mortality (P = 0.833). Regression analysis showed that IABP implantation, recent myocardial infarction, critical status, non-elective operation, and post-operative ventricular fibrillation were risk factors affecting in-hospital mortality (P < 0.01 in all cases). Peri-operative IABP implantation was a protective factor against in-hospital mortality (P = 0.0010). In both the severe and mild left ventricular dysfunction subgroups, peri-operative IABP implantation also exerted a protective role against mortality (P = 0.0303 and P = 0.0101, respectively). CONCLUSIONS Peri-operative IABP implantation could reduce the in-hospital mortality and improve the surgical outcomes of patients with CAD with both severe and mild left ventricular dysfunction.

Patients in acute myocardial infarction (AMI) with serious complications such as malignant ventricular arrhythmia and cardiogenic shock couldn't receive emergency percutaneous coronary intervention (PCI) procedures and had high perioperative mortality. A case of AMI patients who suffered cardiac arrest and long-term cardiopulmonary resuscitation (CPR) was admitted to the department of critical care medicine of the First People's Hospital of Foshan. With the assistance of extracorporeal membrane oxygenation (ECMO), PCI and intra-aortic balloon counterpulsation (IABP) were performed. ECMO and ventilator were successfully weaned after anti-shock, mechanical ventilation, organ support treatment. The patient was successfully treated and discharged. After 6 months of follow-up, the patient recovered well in heart function.

BACKGROUNDPrevious studies showed that patients with cardiogenic shock (CS) from ST-elevation acute myocardial infarction (STEMI) supported by intra-aortic balloon pump (IABP) before primary percutaneous coronary intervention (PCI) decreased the risk of in-hospital mortality than patients who received IABP after PCI. However, little evidence is available on the optimal order of IABP insertion and primary PCI. The aim of this study was to investigate the impact of the sequence of IABP support and PCI and its association with major adverse cardiac and cerebrovascular events (MACCEs).

METHODSData were obtained from 218 consecutive patients with CS due to STEMI in Beijing Anzhen Hospital between 2008 and 2014, who were treated with IABP and PCI. The patients were divided into two groups: Group A in whom IABP received before PCI (n = 106) and Group B in whom IABP received after PCI (n = 112). We evaluated the myocardial perfusion using myocardial blush grade and resolution of ST-segment elevation. The primary endpoint was 12-month risk of MACCE.

RESULTSMost baseline characteristics were similar in patients between the two groups. However, patients received IABP before PCI were associated with a delay of door-to-balloon time (DBT) and higher troponin I level (P < 0.05). However, myocardial perfusion was significantly improved in patients treated with IABP before PCI (P < 0.05). Overall, IABP support before PCI was not associated with significantly lower risk of MACCE (P > 0.05). In addition, risk of all-cause mortality, bleeding, and acute kidney injury (AKI) was similar between two groups (P > 0.05). Multivariate analysis showed that DBT (odds ratio [OR] 2.5, 95% confidence interval [CI] 1.1-4.8, P = 0.04), IABP support after PCI (OR 5.7, 95% CI 2.7-8.4, P = 0.01), and AKI (OR 7.4, 95% CI 4.9-10.8, P = 0.01) were the independent predictors of mortality at 12-month follow-up.

CONCLUSIONSEarly IABP insertion before primary PCI is associated with improved myocardial perfusion although DBT increases. IABP support before PCI does not confer a 12-month clinical benefit when used for STEMI with CS.

BACKGROUND AND PURPOSE: External counterpulsation (ECP) is a noninvasive method used to enhance cerebral perfusion by elevating the blood pressure in ischemic stroke. However, the response of the beat-to-beat blood pressure variability (BPV) in ischemic stroke patients during ECP remains unknown. METHODS: We enrolled recent ischemic stroke patients and healthy controls. Changes in the blood flow velocities in bilateral middle cerebral arteries and the continuous beat-to-beat blood pressure before, during, and after ECP were monitored. Power spectral analysis revealed that the BPV included oscillations at very low frequency (VLF; <0.04 Hz), low frequency (LF; 0.04-0.15 Hz), and high frequency (HF; 0.15-0.40 Hz), and the total power spectral density (TP; <0.40 Hz) and LF/HF ratio were calculated. RESULTS: We found that ECP significantly increased the systolic and diastolic blood pressures in both stroke patients and controls. ECP decreased markedly the systolic and diastolic BPVs at VLF and LF and the TP, and the diastolic BPV at HF when compared with baseline. The decreases in diastolic and systolic BPV reached 37.56% and 23.20%, respectively, at VLF, 21.15% and 12.19% at LF, 8.76% and 16.59% at HF, and 31.92% and 23.62% for the total TP in stroke patients, which did not differ from those in healthy controls. The change in flow velocity on the contralateral side was positively correlated with the total TP systolic BPV change induced by ECP (r=0.312, p=0.035). CONCLUSIONS: ECP reduces the beat-to-beat BPV when increasing the blood pressure and cerebral blood flow velocity in ischemic stroke patients. ECP might be able to improve the clinical outcome by decreasing the beat-to-beat BPV in stroke patients, and this should be explored further in future studies.

PURPOSE: We aimed to investigate the clinical use of plasma neutrophil gelatinase-associated lipocalin (NGAL) in the emergency department (ED), especially for predicting the prognosis of heart failure. METHODS: In a retrospective study, patient selection was based on those who visited the ED between January 2015 and September 2015 and were diagnosed with heart failure and underwent laboratory tests, including B-type natriuretic peptide (BNP) and NGAL. They were divided in two groups, according to the presence or absence of the following events: one or more intubations, admission of intensive care unit (ICU), coronary angiography, renal replacement therapy, extracorporeal membrane oxygenation, intra-aortic balloon pumping, cardiopulmonary resuscitation (CPR), or death. RESULTS: We studied 63 patients with heart failure. The absence group consisted of 29 subjects, and the presence group consisted of 34 subjects. Patients who were younger, had a history of diabetes mellitus, had high level of serum creatinine, low estimated glomerular filtration (eGFR), high creatine kinase (CK) or high NGAL were associated with higher incidence of events and were statistically significant (p<0.001, 0.02, 0.005, 0.035, 0.03, 0.003). In the case of BNP, the presence group showed a higher value compared with the absence group, but was not statistically significant. In a multivariated logistic regression, age (OR=0.868, 95% confidence interval 0.788-0.956, p=0.004) and NGAL (OR=1.004, 95%CI 1.001-1.007, p=0.021) were considered as meaningful factors for predicting the event. CONCLUSION: NGAL elevation in this study showed to be a meaningful factor, indicating a prognosis to those patients who visited the ED and were diagnosed as heart failure.

To analyze two common factors for perioperative ischemic stroke in patients with concomitant carotid and coronary artery severe stenosis and to improve the therapeutic effect.
 Methods: A total of 44 patients with multi-vessel coronary artery disease combined with carotid stenosis, who admitted to the Department of Cardiac Surgery, the First Affiliated Hospital of Xiamen University from 2008 to 2014, were enrolled in this study. Among them, 32 cases were male, 12 cases was female. All patients received coronary artery bypass grafting after treatment of neck diseases. The surgical outcomes and follow-up results were analyzed retrospectively.
 Results: One patient received carotid endarterectomy suffered hemiplegia, whose symptoms were improved after positive clinical treatment. One patient suffered transient ischemic attack, and 5 patients displayed the cerebrovascular syndromes a week later after surgery. Twelve patients suffered nerve function damage 48 hours later after surgery. Nine patients received intra-aortic ballon pump, 1 patient received thoracotomy hemostasis, 3 patients suffered sternal dehiscence; 27 patients showed atrial fibrillation. Two patients died after surgery. The follow-up duration ranged from 1-7 years and the follow-up rate was 90%. The ischemic symptoms were improved in 44 patients. Six patients complained the recurrence of angina, but no abnormalities were found in coronary angiography or computed tomography angiography. One patient died of malignant tumor during the follow-up duration.
 Conclusion: For patients with concomitant carotid and coronary artery severe stenosis, it is more likely to suffer ischemic cerebral stroke. However, carotid stenosis is not the only factor, other key factors relevant to ischemic cerebral stroke shouldn't be ignored either.
