A Clinical Comparison of Pycnogenol,Antistax, and Stocking in Chronic Venous Insufficiency

This 8-week registry study was a comparative evaluation of Pycnogenol (French Maritime Pine Bark extract; Horphag Research, Geneva) and Antistax (grape leaf extract [GLE, Boehringer Ingelheim, Germany]) in controlling symptoms of chronic venous insufficiency (CVI). “Standard management” for CVI is compression; a group of comparable subjects was monitored to evaluate the effects of stockings. The registry included 183 patients (166 completing). Supplementation with Antistax (two tablets of 360 mg/d) or Pycnogenol (100 mg/d) was used. The groups were comparable for age, symptoms, venous incompetence, and microcirculation (with increased capillary filtration and skin flux) at inclusion. At 8 weeks, the rate of swelling (p < 0.05) and skin flux decreased toward normal values; changes were more important with Pycnogenol (p < 0.05). Transcutaneous Po ₂ was increased more with Pycnogenol (p < 0.05). Ankle circumference was decreased more (p < 0.05) with Pycnogenol. An analog scale quantified symptoms. At 8 weeks, pain and edema were decreased with Pycnogenol and elastic compression (p < 0.05) with prevalence for Pycnogenol (p < 0.05). Edema with Pycnogenol was decreased by 40%. Induration was reduced only in the Pycnogenol group (p < 0.05) with minimal variations in the other groups. Tolerability and compliance were optimal. Elastic compression was correctly used by 80% of the patients indicating that it may be more difficult to use, particularly in warmer days. Costs for Pycnogenol were lower (96; 3.3 Euros) in comparison with the other groups (132;1.4 Euros for GLE and 149; 2.2 Euros for compression).     

Associated Venous Injury Significantly Complicates Presentation,Management, and Outcomes of Axillosubclavian Arterial Trauma

Axillosubclavian vessel injury (ASVI) is associated with high morbidity and mortality. Most studies are single-center experiences of small numbers of patients with penetrating injury. We assessed 21st-century presentation and management of ASVI and focused on outcomes of combined arterial/venous injury. We reviewed the National Trauma Data Bank for patients with isolated arterial ASVI (group 1) and combined arterial/venous ASVI (group 2). Demographics, injury severity parameters, interventions, complications, and outcomes were compared. We identified 581 patients with ASVI (mean age 35.1; 88.1% male), with 466 isolated arterial injuries and 115 combined arterial/venous injuries. Group 2 had lower presenting systolic blood pressure and Glasgow Coma Scale, and had higher rates of operative repair (55.7 vs. 43.1%, p = 0.016) and higher mortality (33.9 vs. 13.9%, p < 0.001). There were no differences in amputation (5.2 vs. 2.4%, p = 0.121), compartment syndrome (2.6 vs. 1.9%, p = 0.713), and deep vein thrombosis (0.9 vs. 0.2%, p = 0.357). When separated by mechanism of injury, combined injuries from blunt trauma did increase amputation rates (27.8 vs. 4.2%, p = 0.002). Multivariate analysis revealed that combined arterial/venous injury significantly increased risk of death (odds ratio [OR], 2.99; confidence interval [CI], 1.73 to 5.17; p = 0.0001). Penetrating injury had higher odds of death than blunt injury (OR, 1.96; CI, 1.03 to 3.73; p = 0.041). ASVI is rare but extremely lethal. Concomitant venous and arterial injury is not associated with worse limb-related outcomes, except in blunt injuries and resultant amputations, but is associated with a threefold increase in mortality rates compared with isolated arterial injury.     

Longitudinal association between cognitive depressive symptoms and D‐dimer levels in patients following acute myocardial infarction

BackgroundA prothrombotic tendency could partially explain the poor prognosis of patients with coronary heart disease and depression. We hypothesized that cognitive depressive symptoms are positively associated with the coagulation activation marker D‐dimer throughout the first year after myocardial infarction (MI).MethodsPatients with acute MI (mean age 60 years, 85% men) were investigated at hospital admission (n = 190), 3 months (n = 154) and 12 months (n = 106). Random linear mixed regression models were used to evaluate the relation between cognitive depressive symptoms, assessed with the Beck depression inventory (BDI), and changes in plasma D‐dimer levels. Demographics, cardiac disease severity, medical comorbidity, depression history, medication, health behaviors, and stress hormones were considered for analyses.ResultsThe prevalence of clinical depressive symptoms (13‐item BDI score ≥ 6) was 13.2% at admission and stable across time. Both continuous (p < .05) and categorical (p < .010) cognitive depressive symptoms were related to higher D‐dimer levels over time, independent of covariates. Indicating clinical relevance, D‐dimer was 73 ng/ml higher in patients with a BDI score ≥ 6 versus those with a score < 6. There was a cognitive depressive symptom‐by‐cortisol interaction (p < .05) with a positive association between cognitive depressive symptoms and D‐dimer when cortisol levels were high (p < .010), but not when cortisol levels were low (p > .05). Fluctuations (up and down) of cognitive depressive symptoms and D‐dimer from one investigation to the next showed also significant associations (p < .05).ConclusionsCognitive depressive symptoms were independently associated with hypercoagulability in patients up to 1 year after MI. Hypothalamic–pituitary–adrenal axis could potentially modify this effect.     

Hospitalisation,morbidity and outcomes associated with respiratory syncytial virus compared with influenza in adults of all ages

BackgroundRespiratory syncytial virus (RSV) is understood to be a cause of significant disease in older adults and children. Further analysis of RSV in younger adults may reveal further insight into its role as an important pathogen in all age groups.MethodsWe identified, through laboratory data, adults who tested positive for either influenza or RSV between January 2017 and June 2019 at a single Australian hospital. We compared baseline demographics, testing patterns, hospitalisations and outcomes between these groups.ResultsOf 1128 influenza and 193 RSV patients, the RSV cohort was older (mean age 54.7 vs. 64.9, p < 0.001) and was more comorbid as determined by the Charlson Comorbidity Index (2.4 vs. 3.2, p < 0.001). For influenza hospitalisations, the majority admitted were aged under 65 which was not the case for RSV (61.8% vs. 45.6%, p < 0.001). Testing occurred later in RSV hospitalisations as measured by the proportion tested in the emergency department (ED) (80.3% vs. 69.2%, p < 0.001), and this was strongly associated with differences in presenting phenotype (the presence of fever). RSV was the biggest predictor of 6‐month representation, with age and comorbidities predicting this less strongly.ConclusionRSV is a significant contributor to morbidity and hospitalisation, sometimes outweighing that of influenza, and is not limited to elderly cohorts. Understanding key differences in the clinical syndrome and consequent testing paradigms may allow better detection and potentially treatment of RSV to reduce individual morbidity and health system burden. This growing area of research helps quantify the need for directed therapies for RSV.     

Improvements of Venous Tone with Pycnogenol in Chronic Venous Insufficiency: An Ex Vivo Study on Venous Segments

This study evaluated the stretching and dilatation of venous segments ex vivo in subjects with primary varicose veins in comparison with comparable segments from subjects that used the supplement Pycnogenol (150 mg/d) for 3 months before surgery. Subjects with varicose veins and chronic venous insufficiency voluntarily used Pycnogenol for a period of at least 3 months. The segments of veins removed with surgery (in 30 subjects that had used Pycnogenol and in 10 comparable control subjects that had not used the supplement) were compared with normal, unused vein segments harvested for bypass grafting. The segments were suspended and a weight was attached to the distal part of the veins for 3 minutes and dilated with pressurized water. Digital images were recorded; the veins were measured before and after stretching to evaluate elongation. The manipulation of the vein segment was minimal. Tests were completed within 20 minutes after harvesting the veins. All segments were 4 cm long. The stretching test indicated a significantly higher level of passive elongation in control, varicose segments (2.29; 0.65 mm) in comparison with 1.39; 0.2 mm in vein segments from Pycnogenol-using patients. The dilation test showed an average higher dilation (2.19; 0.3 mm) in control varicose veins in comparison with varicose veins from Pycnogenol-using patients (1.32; 0.7 mm) (p < 0.05). Stretching and dilatation were lower in veins from Pycnogenol-using subjects (p < 0.05). The measurement of destretching and the recovery after dilatation indicated a better tone and recovery of the original size/shape in varicose segments from patients using Pycnogenol. Varicose segments had a more significant persistent dilatation and elongation in comparison with normal vein segments. Pycnogenol seems to decrease passive dilatation and stretching and gives vein walls a greater tonic recovery and elasticity that allows the vein to recover its original shape after dynamic stresses.     

Utilization and in‐hospital complications of catheter ablation for atrial fibrillation in patients with obesity and morbid obesity

BackgroundReal‐world data on atrial fibrillation (AF) ablation outcomes in obese populations have remained scarce, especially the relationship between obesity and in‐hospital AF ablation outcome.HypothesisObesity is associated with higher complication rates and higher admission trend for AF ablation.MethodsWe drew data from the US National Inpatient Sample to identify patients who underwent AF ablation between 2005 and 2018. Sociodemographic and patients'' characteristics data were collected, and the trend, incidence of catheter ablation complications and mortality were analyzed, and further stratified by obesity classification.ResultsA total of 153 429 patients who were hospitalized for AF ablation were estimated. Among these, 11 876 obese patients (95% confidence interval [CI]: 11 422–12 330) and 10 635 morbid obese patients (95% CI: 10 200–11 069) were observed. There was a substantial uptrend admission, up to fivefold, for AF ablation in all obese patients from 2005 to 2018 (p < .001). Morbidly obese patients were statistically younger, while coexisting comorbidities were substantially higher than both obese and nonobese patients (p < .01) Both obesity and morbid obesity were significantly associated with an increased risk of total bleeding, and vascular complications (p < .05). Only morbid obesity was significantly associated with an increased risk of ablation‐related complications, total infection, and pulmonary complications (p < .01). No difference in‐hospital mortality was observed among obese, morbidly obese, and nonobese patients.ConclusionOur study observed an uptrend in the admission of obese patients undergoing AF ablation from 2005 through 2018. Obesity was associated with higher ablation‐related complications, particularly those who were morbidly obese.     

Severe COVID‐19 pneumonia in an intensive care setting and comparisons with historic severe viral pneumonia due to other viruses

PurposeSevere viral pneumonia is associated with significant morbidity and mortality. Recent COVID‐19 pandemic continues to impose significant health burden worldwide, and individual pandemic waves often lead to a large surge in the intensive care unit (ICU) admissions for respiratory support. Comparisons of severe SARS‐CoV‐2 pneumonia with other seasonal and nonseasonal severe viral infections are rarely studied in an intensive care setting.MethodsA retrospective cohort study comparing patients admitted to ICU with COVID‐19 between March and June 2020 and those with viral pneumonias between January and December 2019. We compared patient specific demographic variables, duration of illness, ICU organ supportive measures and outcomes between both groups.ResultsAnalysis of 93 COVID‐19 (Group 1) and 52 other viral pneumonia patients (Group 2) showed an increased proportion of obesity (42% vs. 23%, p = 0.02), non‐White ethnicities (41% vs. 6%, p < 0.001) and diabetes mellitus (30% vs. 13%, p = 0.03) in Group 1, with lower prevalence of chronic obstructive pulmonary disease (COPD)/asthma (16% vs. 34%, p = 0.02). In Group 1, the neutrophil to lymphocyte ratio was much lower (6.7 vs. 10, p = 0.006), and invasive mechanical ventilation (58% vs. 26%, p < 0.001) was more common. Length of ICU (8 vs. 4, p < 0.001) and hospital stay (22 vs. 11, p < 0.001) was prolonged in Group 1, with no significant difference in mortality. Influenza A and rhinovirus were the most common pathogens in Group 2 (26% each).ConclusionsKey differences were identified within demographics (obesity, ethnicity, age, ICU scores, comorbidities) and organ support. Despite these variations, there were no significant differences in mortality between both groups. Further studies with larger sample sizes would allow for further assessment of clinical parameters in these patients.     

The Use of Intra-aortic Balloon Pump in a Real-World Setting: A Comparison between Survivors and Nonsurvivors from Acute Coronary Syndrome Treated with IABP. The Jakarta Acute Coronary Syndrome Registry

Real-world data on acute coronary syndrome (ACS) patients who received intra-aortic balloon pump (IABP) support are limited. The objective of this study was to evaluate the characteristics of ACS patients who received IABP support from a real-world ACS registry. Patients with ACS (N = 121) who received IABP support were enrolled. Characteristics of survivors and nonsurvivors were compared at 30 days. Mortality rate of patients with ACS who received IABP was 47%. The survivors (N = 64) had less often cardiogenic shock (p < 0.001), more often IABP usage as back-up for a revascularization procedure (p = 0.002), less often resuscitation (p = 0.043), and less mechanical ventilator support (p < 0.001) than nonsurvivors. The nonsurvivors had a significantly higher leukocyte count (p = 0.033), a higher serum creatinine level (p < 0.001), a higher blood sugar on admission (p = 0.001), higher creatine kinase MB levels (p = 0.002), and a higher serum uric acid level (p < 0.001), but significantly lower left and right ventricular function (p = 0.014 and p = 0.003, respectively) than survivors. At 30 days, non-ST elevation (STE)-ACS patients had lower mortality rate than ST segment elevation myocardial infarction patients (log-rank test, p < 0.001), and non-STE-ACS patients who had not suffered from cardiogenic shock showed the lowest mortality rate (log-rank test, p < 0.001). By multivariate analysis, a heart rate ≥ 100 beats per minute before IABP insertion was the strongest predictor of 30-day mortality (hazard ratio = 5.69; 95% confidence interval, 1.49 to 21.78; p = 0.011). In ACS patients presenting with either cardiogenic shock, resuscitated, or patients who needed mechanical ventilation suffered from high mortality, despite the use of IABP. IABP appears to be safe and tended to be favorable in noncardiogenic shock ACS patients, particularly non-STE-ACS. A heart rate of ≥ 100 beats per minute prior to IABP insertion was the strongest predictor of 30-day mortality.     

Any Degree of Mitral Regurgitation Found during Invasive Ventriculography is Associated with All-Cause Mortality

Background Using a large database of patients who underwent cardiac catheterization for clinical reasons, we evaluated any association between reported degrees of mitral regurgitation (MR) found during ventriculography, and all-cause mortality. Method Using retrospective angiographic data (collected from the years 1993–1997) from 1,771 patients of the VA Long Beach Health Care System with documented ventriculography, we evaluated any association between various degrees of MR and all-cause mortality. We performed uni- and multivariant analysis, adjusting for age and ejection fraction. Results Any degree of MR was associated with all-cause mortality. Total mortality was 20.2% (296/1,465) in patients with no MR versus 32.7% in patients with mild MR (64/196), p < 0.001. Similar to mild MR, any degree of MR was independently associated with all-cause mortality (all MR, 35.1%, [108/306] vs. no MR, 20.2% [296/1,465], p < 0.001). After adjustment for age and comorbidities, any degree of MR remained independently associated with all-cause mortality (multivariate adjusted odds ratio, 1.7; confidence interval, 1.2–2.3; p < 001). Conclusion The presence of any MR documented on invasive ventriculography is associated with increased total mortality independent of age or ejection fraction. Our finding suggests that even mild MR has negative prognostic significance.     

Vaccine‐preventable disease hospitalized patients with heart failure with reduced ejection fraction

BackgroundOver five million Americans suffer from heart failure (HF), and this is associated with multiple chronic comorbidities and recurrent decompensation. Currently, there is an increased incidence in vaccine‐preventable diseases (VPDs). We aim to investigate the impact of HF with reduced ejection fraction (HFrEF) in patients hospitalized with VPDs.HypothesisPatient with HFrEF are at higher risk for VPDs and they carry a higher risk for in‐hospital complications.MethodsRetrospective analysis from all hospital admissions from the 2016‐2018 National Inpatient Sample (NIS) using the ICD‐10CM codes for patients admitted with a primary diagnosis of VPDs with HFrEF and those without reduced ejection fraction. Outcomes evaluated were in‐hospital mortality, length of stay (LOS), healthcare utilization, frequency of admissions, and in‐hospital complications. Multivariate regression analysis was conducted to adjust for confounders.ResultsOut of 317 670 VPDs discharges, we identified 12 130 (3.8%) patients with HFrEF as a comorbidity. The most common admission diagnosis for VPDs was influenza virus (IV) infection (75.0% vs. 64.1%; p < .01), followed by pneumococcal pneumonia (PNA) (13% vs. 9.4%; p < .01). After adjusting for confounders, patients with HFrEF had higher odds of having diagnosis of IV (adjusted [aOR], 1.42; p < .01) and PNA (aOR, 1.27; p < .01). Patients with VPDs and HFrEF had significantly higher odds of mortality (aOR, 1.76; p < .01), LOS, respiratory failure requiring mechanical ventilation, and mechanical ventilation for less than 96 h.ConclusionInfluenza and PNA were the most common VPDs admitted to the hospital in patients with a concomitant diagnosis of HFrEF. They were associated with increased mortality and in‐hospital complications.     

What are the factors affecting the recovery rate of bronchoalveolar lavage fluid?

BackgroundBronchoalveolar lavage (BAL) is a useful examination for the evaluation of interstitial lung disease. A high BAL fluid (BALF) recovery rate is desirable because low recovery rates lead to inaccurate diagnoses and increased adverse events. Few studies have explored whether BALF recovery rates are influenced by clinical factors.ObjectivesThis study aimed to identify the clinical parameters affecting the recovery rates of BALF and the extent of their effects.MethodData from patients who underwent BAL at the Chiba University Hospital between 2013 and 2019 were retrospectively reviewed. BAL was performed with three aliquots of 50‐ml physiological saline. The potential association of the BALF recovery rate with clinical parameters such as age, sex, smoking status, underlying disease, bronchus used for the procedure and pulmonary function, was analysed.ResultsEight hundred twenty‐six patients had undergone BAL. The average recovery rate was 52.4%. Factors affecting BALF recovery rates included male sex (odds ratio [OR]: 0.32, 95% confidence interval [CI]: 0.20–0.53, p < 0.001); age ≥ 65 years (OR: 0.50, 95% CI: 0.33–0.76, p < 0.001); use of the left bronchus (OR: 0.46, 95% CI: 0.30–0.71, p = 0.001) and bronchi other than the middle lobe bronchus or lingula (OR: 0.41, 95% CI: 0.25–0.65, p < 0.001); and forced expiratory volume in 1 s divided by forced vital capacity <80% (OR: 0.42, 95% CI: 0.40–1.00, p < 0.001).ConclusionSex, age, bronchus used for the procedure and pulmonary function may be useful as pre‐procedural predictors of BALF recovery rates.     

Kidney-Pancreas Transplant Recipients Experience Higher Risk of Complications Compared to the General Population after Undergoing Coronary Artery Bypass Grafting

This retrospective analysis aims to identify differences in surgical outcomes between pancreas and/or kidney transplant recipients compared with the general population undergoing coronary artery bypass grafting (CABG). Using Nationwide Inpatient Sample (NIS) data from 2005 to 2014, patients who underwent CABG were stratified by either no history of transplant, or history of pancreas and/or kidney transplant. Multivariate analysis was used to calculate odds ratio (OR) to evaluate in-hospital mortality, morbidity, length of stay (LOS), and total hospital charge in all centers. The analysis was performed for both nonemergency and emergency CABG. Overall, 2,678 KTx (kidney transplant alone), 184 PTx (pancreas transplant alone), 254 KPTx (kidney-pancreas transplant recipients), and 1,796,186 Non-Tx (nontransplant) met inclusion criteria. KPTx experienced higher complication rates compared with Non-Tx (78.3 vs. 47.8%, p  < 0.01). Those with PTx incurred greater total hospital charge and LOS. On weighted multivariate analysis, KPTx was associated with an increased risk for developing any complication following CABG (OR 3.512, p  < 0.01) and emergency CABG (3.707, p  < 0.01). This risk was even higher at transplant centers (CABG OR 4.302, p  < 0.01; emergency CABG OR 10.072, p  < 0.001). KTx was associated with increased in-hospital mortality following emergency CABG, while PTx and KPTx had no mortality to analyze. KPTx experienced a significantly higher risk of complications compared with the general population after undergoing CABG, in both transplant and nontransplant centers. These outcomes should be considered when providing perioperative care.     

Gastric Diffuse Large B-Cell Lymphoma: A Single-Center 9-Year Experience

Gastric diffuse large B cell lymphoma (DLBCL) represents the majority of all gastric lymphomas. We report a series of gastric DLBCL diagnosed and treated in a single center, between 2010 and 2018 (included). We retrospectively analyzed the population demographic features, treatment outcomes and survival. One-hundred-and-one patients were studied, 50.5% males and median age of 64 years [23–94]. Lugano staging was I in 16.8%, II1 in 20.8%, II2 in 10.9%, IIE in 13.9% and IV in 34.7% of cases. Twenty percent had Helicobacter pylori infection. R-CHOP-like therapy was used as first line in 96.9% of the patients. A complete response was achieved in 80% after first line therapy. At 3-years of follow-up (FU), 54% were in complete remission. The mean FU time was 73.6 months. Median overall survival and median progression free survival were not reached. We identified seven factors with negative impact in survival: age above 65 years-old (p < 0.01), ECOG 2–3 (p < 0.01), B symptoms (p = 0.001), bulky disease (p = 0.003), IPI 3–4 (p = 0.001), more than 3 treatment lines (p < 0.01), absence of response to first line treatment (p < 0.01). This study demonstrates that gastric DLBCL is a potentially curable disease with R-CHOP-like therapy, entailing long term survival and comparing well with other published series.     

Diabetes mellitus and its impact on mortality rate and outcome in pulmonary embolism

Aims/IntroductionIn patients with pulmonary embolism (PE), the impact of diabetes mellitus on patient profile and outcome is not well investigated.Material and MethodsThe German nationwide inpatient sample of the years 2005–2018 was analyzed. Hospitalized PE patients were stratified for diabetes, and the impact of diabetes on in‐hospital events was investigated.ResultsOverall, 1,174,196 PE patients (53.8% aged ≥70 years, 53.5% women) and, among these, 219,550 (18.7%) diabetes patients were included. In‐hospital mortality rate amounted to 15.8%, and was higher in diabetes patients than in non‐diabetes patients (19.8% vs 14.8%, P < 0.001). PE patients with diabetes had a higher prevalence of cardiovascular risk factors, comorbidities, right ventricular dysfunction (31.8% vs 27.7%, P < 0.001), prolonged in‐hospital stay (11.0 vs 9.0 days, P < 0.001) and higher rates of adverse in‐hospital events. Remarkably, diabetes was independently associated with increased in‐hospital mortality (odds ratio [OR] 1.21, 95% confidence interval [CI] 1.20–1.23, P < 0.001) when adjusted for age, sex and comorbidities. Within the observation period of 2005–2018, a relevant decrease of in‐hospital mortality in PE patients with diabetes was observed (25.5% to 16.8%). Systemic thrombolysis was more often administered to diabetes patients (OR 1.18, 95% CI 1.01–3.49, P < 0.001), and diabetes was associated with intracerebral (OR 1.19, 95% CI 1.12–1.26, P < 0.001), as well as gastrointestinal bleeding (OR 1.11, 95% CI 1.07–1.15, P < 0.001). Type 1 diabetes mellitus was shown to be a strong risk factor in PE patients for shock, right ventricular dysfunction, cardiopulmonary resuscitation and in‐hospital death (OR 1.75, 95% CI 1.61–1.90, P < 0.001).ConclusionsDespite the progress in diabetes treatments, diabetes is still associated with an unfavorable clinical patient profile and higher risk for adverse events, including substantially increased in‐hospital mortality in acute PE.     

Impact of Timing of Eptifibatide Administration on Preprocedural Infarct-Related Artery Patency in Acute STEMI Patients Undergoing Primary PCI

The appropriate timing of eptifibatide initiation for acute ST segment elevation myocardial infarction (STEMI) patients undergoing primary percutaneous coronary intervention (PCI) remains unclear. This study aimed to analyze the impact of timing of eptifibatide administration on infarct-related artery (IRA) patency in STEMI patients undergoing primary PCI. Acute STEMI patients who underwent primary PCI (n = 324) were enrolled in this retrospective study; 164 patients received eptifibatide bolus ≤ 30 minutes after emergency department (ED) admission (group A) and 160 patients received eptifibatide bolus > 30 minutes after ED admission (group B). The primary endpoint was preprocedural IRA patency. Most patients in group A (90%) and group B (89%) were late presenters (> 2 hours after symptom onset). The two groups had similar preprocedural thrombolysis in myocardial infarction 2 or 3 flow of the IRA (26 vs. 24%, p = not significant [NS]), similar creatine kinase-MB (CK-MB) levels at 8 hours after admission (339 vs. 281 U/L, p = NS), similar left ventricular ejection fraction (LVEF) (52 vs. 50%, p = NS), and similar 30-day mortality (2 vs. 7%, p = NS). Compared with group B, patients in group A had shorter door-to-device time (p < 0.001) and shorter procedural time (p = 0.004), without increased bleeding risk (13 vs. 18%, p = NS). Earlier intravenous administration of eptifibatide before primary PCI did not improve preprocedural IRA patency, CK-MB level at 8 hours after admission, LVEF and 30-day mortality compared with patients who received intravenous eptifibatide that was administered later.     

Manual Aspiration Thrombectomy in Acute Myocardial Infarction: A Clinical Experience

Multiple clinical studies have failed to establish the role of routine use of thrombectomy in ST-elevation myocardial infarction (STEMI) patients. There is a paucity of data on the impact of thrombectomy in unselected STEMI patients outside clinical trials. We sought to evaluate the clinical variables and outcomes associated with the performance of thrombectomy in STEMI patients. We retrospectively examined the clinical outcomes in all STEMI patients who underwent successful percutaneous intervention (PCI) at our center. Patients were divided into two groups, one with patients who underwent conventional PCI and another with patients who had thrombus aspiration in addition to conventional PCI. We compared the baseline clinical characteristics, laboratory investigations, re-infarction rates, and all-cause mortality. Total 477 consecutive STEMI patients were identified. Overall, 29% (139) of the patients underwent conventional PCI and 71% (338) of the patients were treated with aspiration thrombectomy and PCI. In addition to the presence of thrombus, patients with nonanterior infarction, and patients with hemodynamic instability requiring intra-aortic balloon pump support were more likely to undergo thrombectomy. Thrombectomy was associated with higher enzymatic infarction (creatine kinase: 2,796 [2,575] vs. 1,716 [1,662]; p < 0.0001; CK-MB: 210.6 [156.0] vs. 142.0 [121.9], p < 0.0001). However, thrombectomy was not associated with any difference in 30 day reinfarction rate (3.3 vs. 2.9%, p = 0.83), mortality (5.0 vs. 7.2%, p = 0.35), or composite of death and 30 day reinfarction (7.7 vs. 9.4%, p = 0.55). We observed that STEMI patients with anterior infarction and hemodynamic instability were more likely to undergo thrombectomy during primary PCI.     

Value of acoustic cardiography in the clinical diagnosis of coronary heart disease

BackgroundTo investigate the clinical value of acoustic cardiography in the diagnosis of coronary artery disease (CAD) and post‐percutaneous coronary intervention (PCI) early asymptomatic left ventricular systolic dysfunction.MethodsInpatients in the department of cardiology were included in the research (n = 315); including 180 patients with angina pectoris and 135 patients with acute anterior wall myocardial infarction after emergency PCI did not present with signs and symptoms of heart failure. Color Doppler echocardiography, brain natriuretic peptide, acoustic cardiography examination were performed. The patients were divided into four groups: non‐CAD group (n = 60), CAD group (n = 120), MIREF group (EF% < 50%, n = 75), and MINEF group (EF% ≥ 50%, n = 60).ResultsAcoustic cardiography parameters EMATc, systolic dysfunction index, S3 strength and S4 strength in the MIREF group were higher than those in MINEF group (p < .05), and the MINEF group was higher than CAD group (p < .05). S3 strength (area under the curve [AUC] 0.67, 95% CI 0.585–0.755, p < .001) and S4 strength (AUC 0.617, 95% CI 0.536–0.698, p = .011) are useful in the diagnosis of CAD. S3 strength (AUC 0.942, 95% CI 0.807–0.978, p < .001) was superior to other indicators in the diagnosis of early left ventricular systolic dysfunction after myocardial infarction.ConclusionS4 combined with STT standard change can improve the diagnosis of CAD. Acoustic cardiography can be used as a non‐invasive, rapid, effective, and simple method for the diagnosis of asymptomatic left ventricular systolic dysfunction in the early stage after myocardial infarction.     

The alterations of retinal vasculature detected on optical coherence tomography angiography associated with chronic obstructive pulmonary disease

ObjectivesThis study aimed to evaluate the retinal vasculature of the macula and optic disc in patients with chronic obstructive pulmonary disease (COPD) by optical coherence tomography angiography (OCTA).MethodsThe right eyes of 70 COPD patients and 71 healthy individuals were evaluated. These patients had moderate airflow limitation and mean PO₂ of 60 mmHg, and their average age was less than 60 years. Superficial and deep capillary plexus vascular densities, foveal avascular zone (FAZ) width, and optic disc parameters were measured with OCTA. In addition, the correlation between the PO₂ level in COPD patients and superficial, deep, and peripapillary vascular densities and FAZ was examined in the study.ResultsThe COPD group had a significant decrease in the vascular density in the superficial (fovea [p = 0.019]; parafovea [p = 0.013]; and perifovea [p = 0.001]) and deep capillary plexus (fovea [p = 0.028]; parafovea [p = 0.005]; and perifovea [p = 0.002]). Also, the enlargement of the FAZ (p = 0.002) and a decrease in the peripapillary vascular density (p = 0.006) were observed in the COPD group. There was a positive correlation between PO₂ level and superficial, deep, and peripapillary vascular densities in COPD patients and a negative correlation with FAZ (r = 0.559–0.900).ConclusionHypercapnia, respiratory acidosis, and chronic hypoxia associated with COPD may affect the macula and optic nerve, resulting in a serious decrease in vascular density, and OCTA can be a very important tool in the follow‐up and treatment of these patients.     

Asthma,from mild to severe,is an independent prognostic factor for mild to severe Coronavirus disease 2019 (COVID‐19)

BackgroundChronic illnesses were reported to be poor prognostic factors associated with severe illness and mortality in Coronavirus disease 2019 (COVID‐19) infection. The association with asthma, however, is limited and controversial, especially for mild asthma.MethodsA territory wide retrospective study was conducted to investigate the association between asthma and the prognosis of COVID‐19. All patients with laboratory confirmed in Hong Kong for COVID‐19 from the 23 January to 30 September 2020 were included in the study. Severe diseases were defined as those who develop respiratory complications, systemic complications, and death.ResultsAmong the 4498 patients included in the analysis, 165 had asthma, with 141 having mild asthma. Patients with asthma were significantly more likely to require invasive mechanical ventilation (incidence = 17.0% odds ratio [OR] = 4.765, p < 0.001), oxygen therapy (incidence = 39.4%, OR = 3.291, p < 0.001), intensive care unit admission (incidence = 21.2%, OR = 3.625, p < 0.001), and systemic steroid treatment (incidence = 34.5%, OR = 4.178, p < 0.001) and develop shock (incidence = 16.4%, OR = 4.061, p < 0.001), acute kidney injury (incidence = 6.1%, OR = 3.281, p = 0.033), and secondary bacterial infection (incidence = 56.4%, OR = 2.256, p < 0.001). They also had significantly longer length of stay. Similar findings were also found in patients with asthma of the Global Initiative for Asthma (GINA) steps 1 and 2 upon subgroup analysis.ConclusionsAsthma, regardless of severity, is an independent prognostic factor for COVID‐19 and is associated with more severe disease with respiratory and systemic complications.
