Abstract Late recovery of left ventricular function in patients with non-severe ischemic mitral regurgitation and multivessel disease qualified to cardiosurgery treatment. Purpose In patients (pts) after myocardial infarction (MI) with chronic left ventricle (LV) dysfunction, the presence and degree of ischemic mitral regurgitation (IMR) are predominantly related to LV remodelling and mitral valvular deformation. The aim of this study was to compare functional recovery (LVFR) as well as reverse remodelling of the left ventricle (LVRR) in pts with non-severe IMR qualified for cardiosurgical treatment - coronary artery bypass grafting alone (CABGa) or CABG with mitral repair (CABGmr in the 12-month follow-up. Materials and methods A total of 100 pts (mean age 64,4 ± 7,9 years) after MI, eligible for CABG, were included in a prospective study. Echo and clinical assessment were performed before and 12-months after surgery. Pts were referred for CABG a(gr.1; n = 74) or CABGmr (gr.2; n = 26) based on clinical assessment, 2D echo at rest and exercise and myocardial viability assessment (low dose dobutamine - dbx). Effective regurgitation orifice area (EROA) was used for quantitative IMR assessment. An increase in EF≥ 5% (ΔEF) from baseline value was considered as LVFR. A decrease in LV end-systolic volume > 15% from baseline value was considered as LVRR. Multivariable logistic regression analysis was used to identify the strongest factors of lack of LVFR and LVRR. Results An LVFR was observed, at late control, in 35 (49%) of pts in the CABGa group and in 11 (48%) of pts in CABGmr group (p = 0,948). LVRR was observed in 41 (56%) of pts in the CABGa group and in 16 (70%) of pts in CABGmr group 12 months follow-up (p = 0,5). In pts with LVFR, there was a lower incidence of at least moderate IMR at follow-up (ΔEF dbx≥5% vs ΔEFdbx < 5%:11% vs 30% pts; p = 0,05). Multivariable logistic regression analysis revealed that in both CABGa and CABGmr group only preoperative age and EF changes during stress echo remained the independent predictors of the lack of LVFR in 12 months follow-up (table 1). Conclusions 1. LVFR and LVRR were reported in most of the pts in both analyzed groups. 2. Preoperative assessment of changes EF during dbx (ΔEFdbx)can be used to identify pts with IMR at increased risk of lack of improvement in LV function and risk of residual IMRin 12-month f-up after surgery. Parameters Odds ratio (OR) Odds ratio (OR) p CABGa vs CABGmr 0,644 0,215 - 1,927 0,432 Age (increase by every 5 years) 1,11 1,039 - 1,879 0,003 ΔEF dbx (increase by every 5%) 0,21 0,096 - 0,46 <0,001 Table 1.

Background: In acute ischemic stroke (AIS) patients due to intracranial atherosclerosis-related occlusions (ICAS-O), despite successful reperfusion with mechanical thrombectomy (MT), unexpected early reocclusion sometimes occurs and worsens clinical outcome. We investigated prevalence, outcomes, and predictors of early reocclusion within 48 hours of MT in AIS due to ICAS-O. Methods: In 557 consecutive AIS patients who underwent MT from January, 2016 to March, 2019 in two stroke centers, 71 patients due to ICAS-O were retrospectively evaluated. We divided them into two groups: patients with early reocclusion and those without. Clinical and angiographical findings and outcomes were compared between the 2 groups. Multivariable logistic regression analysis was used to investigate predictors of early reocclusion after MT. Results: Of 71 patients (aged 72 ± 10 years; 23 women; median NIHSS score, 15), early reocclusion was observed in 11 (15%). The first procedure for recanalization was stent retriever in 25 patients (35%), Penumbra system in 25 patients (35%), and balloon angioplasty in 21 patients (30%). Of these, 63 patients (88%) received rescue therapy (balloon angioplasty, 50; intracranial stenting, 13). In the early reocclusion group, more number of intraprocedural reocclusion (median [IQR], 3 [2-3] vs. 1 [0-1], p < 0.001), a higher rate of remaining stenosis on the final angiography (67.6 ± 5.9% vs 57.3 ± 15.9%, p = 0.044), and a higher rate of procedure-related adverse events (27% vs 5%, p = 0.043) were observed compared to the other group. On logistic regression analysis, a total number of intraprocedural reocclusion was independently associated with early reocclusion (odds ratio, 31.4; 95% confidence interval, 2.6-375.2). Early reocclusion was related to a low rate of favorable outcome at 90 days (modified Rankin Scale ≤ 2, 9% vs 54%, p = 0.007). Conclusions: In AIS patients due to ICAS-O, early reocclusion within 48 hours was not rare and associated with unfavorable outcome. Patients with repeated intraprocedural reocclusion are at high risk for early reocclusion; they might need follow-up angiographical assessment and intensive antithrombotic treatment.

Background: With this study, we sought to identify patient characteristics associated with clopidogrel prescription and its relationship with in-hospital adverse events in an unselected cohort of ACSs patients. Materials and Methods: We studied all consecutive patients admitted at our institution for ACSs from 2012 to 2014. Patients were divided into two groups based on clopidogrel or novel P2Y12 inhibitors (prasugrel or ticagrelor) prescription and the relationship between clopidogrel use and patient clinical characteristics and in-hospital adverse events was evaluated using logistic regression analysis. Results: The population median age was 68 years (57–77 year) and clopidogrel was prescribed in 230 patients (46%). Patients characteristics associated with clopidogrel prescription were older age, female sex, non-ST-elevation ACS diagnosis, the presence of diabetes mellitus and anemia, worse renal and left ventricular functions and a higher Killip class. Patients on clopidogrel demonstrated a significantly higher incidence of in-hospital mortality (4.8%) than prasugrel and ticagrelor-treated patients (0.4%), while a nonstatistically significant trend emerged considering bleeding events. However, on multivariable logistic regression analysis female sex, the presence of anemia and Killip class were the only variables independently associated with in-hospital death. Conclusion: Patients treated with clopidogrel showed a higher in-hospital mortality. However, clinical variables associated with its use identify a population at high risk for adverse events and this seems to play a major role for the higher in-hospital mortality observed in clopidogrel-treated patients.

Ischemic mitral regurgitation (IMR) is a common complication, which is accompanied by myocardial infarction, causing heart failure and leading to poor prognosis. Although several surgical techniques have been reported, certain surgical methods have not been established for treating IMR. We report a successful case of left ventricular posterior wall plication through a left atriotomy over the mitral valve for IMR in a patient who experienced cardiac shock and could not be weaned off mechanical support. Posterior wall plication changed the left ventricle from a spherical to an oval shape, restored the position of papillary muscles and posterior wall, improved leaflet tethering, and prevented further remodeling of the left ventricle. This method may be useful for treating IMR and improve patients’ prognosis.

Background The World Health Organization (WHO) has pointed out that urban taxi drivers and their passengers are at higher risk of transmitting coronavirus disease 19 (COVID-19) due to frequent contact among many people. Facemask wearing is one of the preventive measures recommended to control the transmission of the virus. A lack of evidence of the proportion of facemask wearing among taxi drivers and associated factors in Ethiopia, including Dessie City and Kombolcha Town, hinders the design of targeted interventions to advocate for facemask use. This study was designed to address this gap. Methods A cross-sectional study was conducted among 417 taxi drivers in Dessie City and Kombolcha Town from July to August, 2020. The study participants were selected using a simple random sampling technique after proportionally allocating the sample size from the total number of taxi drivers working in Dessie City and Kombolcha Town. The data were collected by trained data collectors using a structured questionnaire and an on-the-spot observational checklist. The collected data were checked, coded and entered to EpiData version 4.6 and exported to Statistical Package for Social Sciences (SPSS) version 25.0 for data cleaning and analysis. Bivariate (Crude Odds Ratio [COR]) and multivariable (Adjusted Odds Ratio [AOR]) logistic regression analyses were employed using 95% CI (confidence interval). From bivariate logistic regression analysis, variables with p-value < 0.250 were retained into multivariable logistic regression analysis. Then, from the multivariable analysis, variables with p-value < 0.050 were declared as factors significantly associated with facemask wearing among taxi drivers in Dessie City and Kombolcha Town. Main findings The proportion of taxi drivers who wore a facemask was 54.68% [95%CI: 50.10–59.7%]. The majority (58.3%) of drivers were using cloth facemasks, followed by N95 facemasks (24.5%) and surgical facemasks (17.3%). Out of the total 417 taxi drivers, more than two-thirds (69.8%) of them had a good knowledge about COVID-19 and 67.6% of taxi drivers had a positive attitude towards taking precautions against transmission of COVID-19. Three-fourths (74.1%) of the taxi drivers believed that wearing a facemask could prevent COVID-19. More than half (52.5%) felt discomfort when wearing a facemask. Almost three-fourths (72.2%) of taxi drivers felt that the presence of local government pressure helped them to wear a facemask. We found that marital status [AOR = 3.14, 95%CI: 1.97–5.01], fear of the disease [AOR = 2.1, 95%CI: 1.28–3.47], belief in the effectiveness of a facemask [AOR = 5.6, 95%CI: 3.1–10.16] and feeling government pressure [AOR = 3.6, 95%CI: 2.16–6.13] were factors significantly associated with wearing a facemask. Conclusion We found that the proportion of facemask wearers among taxi drivers was relatively low in Dessie City and Kombolcha Town. In order to increase that number, government bodies should work aggressively to encourage more taxi drivers to wear a facemask. We also recommend that government and non-government organizations work very closely together to implement strategies that promote facemask use, including increasing the availability of inexpensive facemasks, and monitoring and controlling facemask use.

Serum uric acid (SUA) is associated with the severity and prognosis of systolic heart failure. We investigated the potential association between SUA and cardiac diastolic dysfunction among total of 744 cardiac patients (202 women and 542 men) who had preserved left ventricular ejection fraction. Presence of diastolic dysfunction was assessed by echocardiographic data, plasma B-type natriuretic peptide concentration, and left ventricular hypertrophy. Univariate analysis showed that the prevalence of diastolic dysfunction increased with increasing SUA value in women, but not in men. When sex-nonspecific SUA quartiles were used, multivariate logistic regression analysis, among female patients who were not taking uric acid lowering medication, showed that the third (SUA, 5.7–6.4 mg) and the fourth (SUA, ≥6.5 mg/dl) SUA quartiles were associated with diastolic dysfunction with an odds ratio of 3.25 ( P < 0.05) and 8.06 ( P < 0.001), respectively, when compared with the first SUA quartile (≤4.7 mg/dl). When sex-specific SUA quartiles were used among these population, multivariate logistic regression analysis showed that the fourth SUA quartile (≥5.7 mg/dl) was associated with diastolic dysfunction with an odds ratio of 5.34 ( P < 0.05) when compared with the first SUA quartile (≤4.1 mg/dl). By contrast, the relationship between SUA and diastolic dysfunction was not significant in men, irrespective of which of the sex-nonspecific or sex-specific SUA quartiles were used. These data indicated that among cardiac patients with preserved ejection fraction, SUA was significantly associated with diastolic dysfunction in women but not in men.

Abstract Background Limited data are available on the clinical significance of lactate clearance (LC) in patients with cardiogenic shock (CS). This study investigated the prognostic role of LC in CS patients. Methods We analyzed data from 628 patients in the RESCUE registry, a multicenter, observational cohort enrolled between January 2014 and December 2018. Univariable logistic regression analysis was performed to determine the prognostic implications of 24 h LC, and then patients were divided into two groups according to the cut-off value of 24 h LC (high lactate clearance [HLC] group vs. low lactate clearance [LLC] group). The primary outcome was in-hospital mortality. We also assessed all-cause mortality at 12 month follow-up and compared the prognostic performance of 24 h LC according to initial serum lactate level. Results In the univariable logistic regression analysis, 24 h LC was associated with in-hospital mortality (odds ratio 0.989, 95% confidence interval [CI] 0.985–0.993, p < 0.001), and the cut-off value for the LC of the study population was 64%. The HLC group (initial 24 h LC ≥ 64%, n = 333) had a significantly lower incidence of in-hospital death than the LLC group (n = 295) (25.5% in the HLC group vs. 42.7% in the LLC group, p < 0.001). During 12 months of follow-up, the cumulative incidence of all-cause death was significantly lower in the HLC group than in the LLC group (33.0% vs. 48.8%; hazard ratio 0.55; 95% CI 0.42–0.70; p < 0.001). In subgroup analysis, 24 h LC predicted in-hospital mortality better in patients with initial serum lactate > 5 mmol/L than in those with serum lactate ≤ 5 mmol/L (c-statistics of initial serum lactate > 5 mmol/L = 0.782 vs. c-statistics of initial serum lactate ≤ 5 mmol/L = 0.660, p = 0.011). Conclusions Higher LC during the early phase of CS was associated with reduced risk of in-hospital and 12 month all-cause mortalities. Patients with LC ≥ 64% during the 24 h after CS onset could expect a favorable prognosis, especially those with an initial serum lactate > 5 mmol/L.

Abstract Purpose The aim of this study was to investigate the clinical impact and post-procedural development of tricuspid regurgitation (TR) in patients undergoing the MitraClip procedure for severe mitral regurgitation. Methods In this present multicentre study, we included 940 patients undergoing MitraClip implantation for symptomatic mitral regurgitation from August 2010 to September 2018. Patients were categorized according to concomitant TR (none or mild vs moderate vs severe) and the prognostic impact of TR on 1-year mortality was evaluated. Moreover, in 377 patients, we assessed 3-months echocardiographic controls to further analyse the post-procedural development of TR. Results At baseline, concomitant TR was graded none/mild in 393 (42%), moderate in 316 (34%), and severe in 231 (25%) patients. During 1-year follow-up, 141 of 940 (15%) patients died. According to mild/none, moderate and severe TR, mortality rates were 13%, 12%, and 23%, respectively, revealing a higher prevalence of death in patients with severe TR (p=0.001). Kaplan-Meier analysis and log-rank test confirmed inferior survival rates for patients with severe TR (p=0.001), while there were no significant difference in survival rates between patients with none/mild vs moderate TR (p=0.561). Regarding 1-year mortality, multivariate cox regression analysis, revealed an odds ratio of 1.739 (1.024–2.953; p=0.041), associated with severe TR. After 3-months follow-up, echocardiography in 377 patients showed following TR grade distributions: 44% none/mild, 37% moderate and 19% severe TR. In 100 patients (27%), TR improved by one or more grades, while 64 patients (17%) showed a TR worsening. In patients with severe TR at baseline, 42 of 91 (46%) patients showed a reduction in TR of one or more grades. Patients with severe TR at baseline, who showed a TR improvement during 3-months follow-up, had lower rates of 1-year mortality (p=0.025). For these patients, in regression analysis, right atrial area was revealed as only predictor of TR improvement after MitraClip procedure [odds ratio 0.958 (0.918–0.999); p=0.046]. Conclusion One-fourth of patients undergoing MitraClip procedure for mitral regurgitation had concomitant severe tricuspid regurgitation which was predictive for worse prognosis. Post-procedural TR improvement of one or more grades was frequent in these patients and was associated with higher survival-rates. Funding Acknowledgement Type of funding source: None

Abstract Introduction More than two-thirds of the pregnant women in Africa have at least one antenatal care contact with a health care provider. However, to achieve the full life-saving potential that antenatal care promises for women and babies, four visits providing essential evidence-based interventions – a package often called focused antenatal care are required. Hence, identifying the factors associated with dropout of maternal health care utilization would have meaningful implications. The study aimed to assess antenatal care dropout and associated factors among mothers delivering in the public health facilities of Dire Dawa town, Ethiopia. Methods Facility-based cross-sectional study was conducted from January 1 to 30, 2020. Proportionate sampling and simple random sampling techniques were used to select 230 women. Data were collected using a structured and pretested interview administered questionnaire during delivery. The data were entered into Epidata version 3.1 and analyzed using SPSS version 20. A binary logistic regression model with a 95 % confidence interval was used to analyze the results. Bivariable analysis (COR [crude odds ratio]) and multivariable analysis (AOR [adjusted odds ratio]) was used to analyze the results. From the bivariable analysis, variables with a p-value < 0.25 were entered into the multivariable logistic regression analysis. From the multivariable logistic regression analysis, variables with a significance level of p-value < 0.05 were taken as factors independently associated with ANC dropout. Result The proportion of antenatal care dropouts was 86 (37.4 %) (95 % CI: 31.3–43.9). In logistic regression analyses, those who had no past antenatal care follow up were more likely to have ANC dropout (AOR = 7.89; 95 % CI: 2.109–29.498) and those who had no professional advice were more likely to have antenatal care dropout (AOR = 4.64 95 % CI: 1.246–17.254). Conclusions This study indicates that a high number of women had antenatal care dropout. Having no past ANC follow-up and professional advice were the major factors of ANC service utilization dropout. Hence, giving more information during the ANC visit is important to reduce the dropout rate from the maternity continuum of care.

For ABO-incompatible liver transplantation (ABO-i LT), therapeutic plasma exchange (TPE) is performed preoperatively to reduce the isoagglutinin titer of anti-ABO blood type antibodies. We evaluated whether perioperative high isoagglutinin titer is associated with postoperative risk of acute kidney injury (AKI). In 130 cases of ABO-i LT, we collected immunoglobulin (Ig) G and Ig M isoagglutinin titers of baseline, pre-LT, and postoperative peak values. These values were compared between the patients with and without postoperative AKI. Multivariable logistic regression analysis was used to evaluate the association between perioperative isoagglutinin titers and postoperative AKI. Clinical and graft-related outcomes were compared between high and low baseline and postoperative peak isoagglutinin groups. The incidence of AKI was 42.3%. Preoperative baseline and postoperative peak isoagglutinin titers of both Ig M and Ig G were significantly higher in the patients with AKI than those without AKI. Multivariable logistic regression analysis showed that preoperative baseline and postoperative peak Ig M isoagglutinin titers were significantly associated with the risk of AKI (baseline: odds ratio 1.06, 95% confidence interval 1.02 to 1.09; postoperative peak: odds ratio 1.08, 95% confidence interval 1.04 to 1.13). Cubic spline function curves show a positive relationship between the baseline and postoperative peak isoagglutinin titers and the risk of AKI. Clinical outcomes other than AKI were not significantly different according to the baseline and postoperative peak isoagglutinin titers. Preoperative high initial and postoperative peak Ig M isoagglutinin titers were significantly associated with the development of AKI. As the causal relationship between high isoagglutinin titers and risk of AKI is unclear, the high baseline and postoperative isoagglutinin titers could be used simply as a warning sign for the risk of AKI after liver transplantation.
