Objective To study the hemodynamic effects of enhanced external counter pulsation(EECP)on typical coronary artery disease and microcirculation angina.Methods A physiological model of the right dominant coronary artery,including the coronary conduit arteries and coronary microcirculation,was established using lumped parameter models.Pathological conditions,such as one-vessel lesions,three-vessel lesions,and microcirculation angina,were simulated.EECP intervention models were established,and the hemodynamic effects of EECP on pathological models was simulated.Results The simulation results of the coronary physiological model,pathological models,and EECP intervention model established in this study were consistent with experimental data in related literature.EECP improved coronary blood flow in all three pathological conditions.For one-vessel lesions,EECP could not recover the blood flow of left main coronary artery to a normal level after the stenosis rate reached 80%-85%.For three-vessel lesions,EECP treatment could not be used if the stenosis rate in one of the three vessels exceeded 90%.For microcirculation angina,EECP was effective when critical condition myocardial blood flow was>1.03 mL/min·g and coronary flow reserve was>1.64.Conclusions The model of coronary disease under EECP interference established in this study meets expectations,and the obtained simulation data have certain reference values for the clinical application of EECP.

Objective To investigate the hemodynamic effects of enhanced external counterpulsation(EECP)on cerebral arteries with different stenoses.Methods Zero-dimensional/three-dimensional multiscale hemodynamic models of cerebral arteries with different stenoses were constructed.Numerical simulations of the EECP hemodynamics were performed under different counterpulsation modes to quantify several hemodynamic indicators of the cerebral arteries.Among them,the mean time-averaged wall shear stress(TAWSS)downstream of the stenosis was in the range of 4-7 Pa,a low percentage of TAWSS risk area,and high narrow branch flow were considered to inhibit the development of atherosclerosis and create a good hemodynamic environment.Results For cerebral arteries with 50%,60%,70%,and 80%stenosis,the hemodynamic environment was optimal in counterpulsation mode when the moment of cuff deflation was 0.5,0.6,0.7,and 0.7 s within the cardiac cycle.Conclusions For 50%stenotic cerebral arteries,the counterpulsation mode with a deflation moment of 0.5 s should be selected.For 60%stenotic cerebral arteries,the counterpulsation mode with a deflation moment of 0.6 s should be selected.For 70%or 80%stenotic cerebral arteries,the counterpulsation mode with a deflation moment of 0.7 s should be selected.As stenosis of the cerebral arteries increases,the pressure duration should be prolonged.This study provides a theoretical reference for the EECP treatment strategy for patients with ischemic stroke with different stenoses.

Objective:This study aimed to evaluate the effect of enhanced external counterpulsation(EECP)on left ventricular function in elderly patients with coronary slow flow phenomenon(CSFP)using two-dimensional speckle tracking echocardiography(2D-STE).Methods:This prospective case-control study included 30 patients aged ≥60 years with no stenotic lesions in the coronary arteries but with slow blood flow phenomenon in more than one major coronary artery who were treated at the Department of Geriatrics, Qilu Hospital, Shandong University, between December 2017 and December 2018, and were divided into a medication group with 16 participants and a medication plus EECP group with 14 participants, using the numerical lottery method.Patients in the group treated with EECP received 6-week 36-h EECP therapy in addition to lifestyle modification and drug treatment.Fourteen patients with normal coronary blood flow served as the control group.Conventional echocardiography and 2D-STE were used to evaluate changes in left ventricular function in the CSF patients before and after drug treatment and EECP.Results:Compared with the control group before treatment, patients in the drug treatment group and the drug treatment plus EECP group showed a decrease in mitral annular early diastolic velocity( P<0.01), an increase in the ratio of peak mitral early diastolic blood flow velocity to the mean peak mitral annular early diastolic velocity( P<0.05), and a decrease in left ventricular longitudinal strain during systole( P<0.01), the longitudinal systolic myocardial strain rate( P<0.01)and the early diastolic longitudinal peak strain rate( P<0.01).There was no statistically significant difference in values from conventional echocardiographic parameters before and after treatment in CSF patients of the medication group(all P>0.05).In the group receiving EECP, there were statistically significant differences in pre-and post-treatment values in ventricular septal early diastolic velocity[(6.22 ± 0.64)cm/s vs.(6.69 ± 0.44)cm/s], lateral wall early diastolic velocity[(8.01±0.68)cm/s vs.(8.41±0.29)cm/s], mitral valve to mitral annulus early diastolic peak velocity ratio[(10.51±1.38) vs.(9.74±0.37)], longitudinal left ventricular systolic strain[(-16.21±0.46)% vs.(-16.80±0.48)%], left ventricular systolic longitudinal strain rate[(-1.29±0.03)s -1vs.(-1.35±0.04)s -1], and early diastolic longitudinal strain rate[(1.35±0.03)s -1vs.(1.40±0.03)s -1](t-values were -3.70、-2.74、2.23、10.25、12.30、-19.15, all P<0.05). Conclusions:2D-STE can evaluate subclinical myocardial dysfunction early and quantitatively in elderly patients with CSF, and objectively reflect changes in left ventricular function before and after clinical intervention with EECP.
Résumé
Resumen ANTECEDENTES: Las anomalías en la inserción placentaria son cada vez más frecuentes en nuestro medio. En la atención de la paciente embarazada es importante la prevención de la pérdida hemática con balones de contrapulsación intraaórticos, como una opción útil. CASO CLÍNICO: Paciente de 38 años, embarazada, con antecedente de parto eutócico y sin enfermedades de interés, ni intervenciones quirúrgicas previas. El seguimiento prenatal se inició a las 17 semanas, con retraso diagnóstico debido a que continuaba en tratamiento anticonceptivo. La invasión trofoblástica estaba limitada al miometrio, sin evidencia de invasión a los órganos vecinos. Se le expusieron a la paciente las posibles complicaciones a fin de minimizar los riesgos de hemorragia masiva, potencialmente mortal en el momento del parto. Puesto que la paciente expresó no desear volver a embarazarse, se le recomendó la histerectomía poscesárea, dejando la placenta in situ. CONCLUSIONES: La oclusión endovascular con balón de contrapulsación intraaórtico es una opción segura y eficaz para minimizar la pérdida de sangre en casos de anomalías en la inserción placentaria. Además del clásico acceso por vía femoral es posible colocarlo por vía axilar, con igual efectividad. La baja tasa de complicaciones maternas y la seguridad, en términos de irradiación fetal, la convierten en una opción razonable en la atención de pacientes embarazadas en quienes se espera una alta pérdida sanguínea.
Abstract BACKGROUND: Anomalies of placental insertion are becoming increasingly common. Prevention of blood loss with intra-aortic counterpulsation balloons is a useful option in the care of pregnant patients. CLINICAL CASE: 38-year-old pregnant woman with a history of euthyroid delivery and no medical or surgical history. Prenatal follow-up was initiated at 17 weeks, with a delay in diagnosis due to the fact that she was still on contraceptive treatment. Trophoblastic invasion was limited to the myometrium with no evidence of invasion into adjacent organs. The patient was counseled on the potential complications to minimize the risk of massive, potentially fatal hemorrhage at delivery. As the patient did not wish to become pregnant again, a post-cesarean hysterectomy was recommended, leaving the placenta in situ. CONCLUSIONS: Endovascular occlusion with intra-aortic balloon counterpulsation is a safe and effective option to minimize blood loss in cases of placental insertion anomalies. In addition to the classical femoral approach, the axillary route can be used with equal efficacy. The low rate of maternal complications and the safety with respect to fetal irradiation make it a reasonable option in the management of pregnant patients in whom high blood loss is expected.
Résumé
Intravascular ventricular assist system (iVAS) is an investigative device in clinical trials for the management of advanced heart failure. It works on the principle of counterpulsation, similar to the classic intra?aortic balloon counterpulsation (IABP).We present a case of a 66?year?old man with iVAS in situ who required emergency laparotomy for a strangulated umbilical hernia. Patients with mechanical circulatory devices (MCD) are presenting more frequently for emergency and even elective noncardiac operations. Managing such patients poses significant challenges to the perioperative team due to its novelty and paucity of management recommendations.
Résumé
Objective:To investigate the immediate and lasting effects of enhanced external counterpulsation(EECP)on blood pressure in elderly patients with hypertension.Methods:In this real-world prospective non-randomized controlled study, the elderly hypertensive patients who were newly diagnosed as hypertension or had poor blood pressure control in the Geriatrics Department of Shandong University Qilu Hospital from May 2019 to December 2019, were enrolled as EECP group, and those with systolic blood pressure(SBP)≥180mmHg(1mmHg=0.133 kPa)or had contraindications for EECP treatment were excluded from EECP group(28 cases). Based on the 1∶1 ratio being consistent with the tendency score-matching method, patients' blood pressure was matched at 3 d before the start of the EECP treatment course, with other matched data of baseline data, coexisting disease, cardiovascular medication were choosed as control group(n=28). The EECP group received an additional 36 hours of EECP treatment(6 times/week, 1 hour/time)including lifestyle improvement and anti-hypertensive drugs.The patient's supine blood pressure was collected 3 minutes before each EECP treatment(baseline), 30 minutes during treatment, and 3 minutes after treatment.In the EECP group, family self-measured blood pressure was collected 3 days before the start of the 6-week treatment course(0w), the 6th week(6w)of the treatment course, and the 2nd week(+ 2w), 4th week(+ 4w)and 12th week(+ 12w)after the end of the treatment course, respectively.And the data of control group were collected at the same time point mentioned above.Results:Compared with baseline, the average immediate SBP of elderly hypertensive patients at the 30th minute of EECP treatment was decreased by(5.5±13.6)mmHg( P<0.001), and the average immediate diabolic blood pressure(DBP)was decreased by(1.1±7.5)mmHg( P<0.001). When the baseline SBP was between 160 and 169 mmHg, the probability of a further increase in SBP during treatment was 2.2%(2/89 cases), and when the baseline SBP was between 170 and 179 mmHg, the probability of a further increase in SBP during treatment was 0%(0/57). At 6 weeks, the decrease in SBP was significantly greater in the EECP group than in the control group[(-17.0±8.7)mmHg vs.(-10.5±7.3)mmHg, P<0.01], and the difference continued to + 2w[(-15.5±6.6)mmHg vs.(-10.6±2.5)mmHg, P<0.01]and + 4w[(-13.3±5.4)mmHg vs.(-10.7±2.1)mmHg, P<0.05]. At + 12w, the blood pressure drop was still greater in EECP group than in the control group, but it did not achieve statistically significant differences.Smoking history, history of diabetes, family history of hypertension, and improvement of comorbidities were the key factors that affect the continuous anti-hypertensive effect of EECP. Conclusions:EECP treatment has an immediate effect on lowering blood pressure in elderly hypertensive patients.A 6-week course of EECP treatment has a sustained effect on lowering blood pressure, and the effect can last from 4 to 12 weeks after the end of the course of treatment.
Résumé
The aim of this study was to investigate the influence of enhanced external counterpulsation (EECP) on the cardiac function of beagle dogs after prolonged ventricular fibrillation. Twenty-four adult male beagles were randomly divided into control and EECP groups. Ventricular fibrillation was induced in the animals for 12 min, followed by 2 min of cardiopulmonary resuscitation. They then received EECP therapy for 4 h (EECP group) or not (control group). The hemodynamics was monitored using the PiCCO2 system. Blood gas and hemorheology were assessed at baseline and at 1, 2, and 4 h after return of spontaneous circulation (ROSC). The myocardial blood flow (MBF) was quantified by 18F-flurpiridaz PET myocardial perfusion imaging at baseline and 4 h after ROSC. Survival time of the animals was recorded within 24 h. Ventricular fibrillation was successfully induced in all animals, and they achieved ROSC after cardiopulmonary resuscitation. Survival time of the control group was shorter than that of the EECP group [median of 8 h (min 8 h, max 21 h) vs median of 24 h (min 16 h, max 24 h) (Kaplan Meyer plot analysis, P=0.0152). EECP improved blood gas analysis findings and increased the coronary perfusion pressure and MBF value. EECP also improved the cardiac function of Beagles after ROSC in multiple aspects, significantly increased blood flow velocity, and decreased plasma viscosity, erythrocyte aggregation index, and hematocrit levels. EECP improved the hemodynamics of beagle dogs and increased MBF, subsequently improving cardiac function and ultimately improving the survival time of animals after ROSC.

Objective To investigate the effect of enhanced external counterpulsation (EECP) on plasma lipoprotein phospholipase A2 (LP-PLA2) levels, vascular endothelial diastolic function in patients with unstable angina. Methods One hundred patients with unstable angina treated in our hospital were randomly divided into routine treatment group (control group n-49) and external counterpulsation group (observation group n = 51, routine treatment plus external counterpulsation therapy, 60 min/time, a total of 30 times). All selected subjects were tested for LP-PLA2 levels on the day of enrollment and on the 30 th day after treatment, and color Doppler ultrasonography was used to detect arterial blood flow-mediated vasodilation (FMD) and nitroglycerin-mediated vasodilation (NMD). Results After treatment in the observation group, LP-PLA2 decreased compared with before treatment, the difference was statistically significant (P < 0.05) , but FMD, NMD were higher than those before treatment, which had statistical difference (P < 0.05). In control group treatment afterwards, LP-PLA2, endothelium-dependent vasodilatation and non-endothelium-dependent vasodilatation did not change significantly before treatment (P> 0.05). Observations between groups showed that the increase in FMD and NMD in the observation group was significantly greater than that in the control group. P < 0.01) , plasma LP-PLA2 levels in the observation group also decreased compared with the control group (P < 0.05). Conclusion Enhanced external counterpulsation can reduce the level of LP-PLA2 in patients and improve endothelial diastolic function under the action of blood flow shear stress.

Objective: To compare the prognosis of intra-aortic balloon pump (IABP) supported primary percutaneous coronary intervention (PPCI) between very elderly (age ≥ 80 years) and elderly (age < 80 years) patients with ST-segment elevation myocardial infarction (STEMI). Methods: A total of 288 STEMI patients received IABP supported PPCI in our hospital from 2004-01 to 2015-12 were retrospectively studied. Clinical condition, coronary angiography and follow-up data were analyzed; the patients with pre-operative cardiac shock, mechanical complication and non ST-segment elevation acute coronary syndrome were excluded. Eligible patients were divided into 2 groups: Very elderly group, n=51 and Elderly group, n=237. Major adverse cardiac and cerebral events (MACCE) as death, cardiac shock, new or worsen heart failure, re-MI and stroke were studied at 1 month and 1, 2 years after PPCI. Independent predictors for MACCE occurrence were investigated by Cox proportional hazard model analysis.Results: Compared with Elderly group, Very elderly group had increased incidence of MACCE at 1 month after PPCI (41.2% vs 24.5%), P=0.029 and obviously elevated incidence of stroke (9.8% vs 0.8%), P<0.001. Mortalities were similar between 2 groups at 1 month and 1 year after PPCI (17.6% vs 15.2%) and (25.5% vs 16.9%), both P>0.05; mortality was higher in Very elderly group at 2 years after PPCI (35.3% vs 20.7%), Log-rank P=0.037. Cox proportional hazard model analysis indicated that post-operative TIMI flow < 3 was the strong independent predictor for MACCE occurrence (HR=3.41, 95% CI 2.09-5.56, P<0.001), which was also the strongest predictor for death at different time points as at 1 month after PPCI (HR=9.51, 95% CI 5.23-17.29), at 1 year after PPCI (HR=7.24, 95% CI 4.13-12.69) and at 2 years after PPCI (HR=5.85, 95% CI 3.45-9.94), all P<0.001. Patients ≥ 80 years had no obvious predictors for end point event occurrence. Conclusion: Very elderly STEMI patients had the higher mortality at 2 years after IABP supported PPCI and increased incidence of MACCE at 1 month after PPCI. Patients≥80 years had no obvious predictors for end point event occurrence.

Methods: We performed aretrospectively study in octogenarian STEMI patients treated in our hospital from 2004-01 to 2014-08. The patients were divided into 2 groups: P-IABP group,n=24 and PPCI group,n=73 including 12 patients who received rescue IABP (R-IABP) because of intra- or post-procedural hemodynamic collapse as a subgroup.Major end point events included 1 month and 1-, 2-year post-operative death; major adverse cardiac and cerebral events (MACCE) included 1 month post-operative cardiac shock, new or worsening heart failure (HF), re-infarction and stroke. The predictors causing different endpoint events were identiifed by Cox proportional hazard model analysis. Results: 1 month and 1-, 2-year post-operative death were similar between 2 groups (8.3% vs 16.4%), (16.7% vs 24.7%), (25.0% vs 30.1%) respectively; MACCE incidence was also similar (20.8% vs 30.1%), allP>0.05. Death rates between P-IABP group and R-IABP subgroup were similar at different time points,P>0.05; while MACCE incidence in P-IABP group was lower than R-IABP subgroup (20.8% vs 66.7%),P=0.005 and it was mainly presented by reduced HF occurrence (8.3% vs 41.7%),P=0.003. Coxproportional hazard model analysis indicated that post-operative TIMI lfow<3 grade was the independent predictor for 1 month death (HR=4.79, 95% CI1.59-14.39,P=0.005), complicating diseases as chronic obstructive pulmonary disease, kidney impairment and anemiawere themain independent predictors for 2-year death (HR=3.0, 95% CI 1.37-6.56,P=0.006). Conclusion: PPCI and P-IABP had no signiifcant differencefor short and long term survivalin octogenarianSTEMIpatients. Compared with R-IABP, P-IABP patients had the lower MACC Eincidence at 1 month post-operation .
