Electrocardiographic approach strategies in patients with Parkinson disease treated with deep brain stimulation.

Deep brain stimulation (DBS) is an interdisciplinary and reversible therapy that uses high-frequency electrical stimulation to correct aberrant neural pathways in motor and cognitive neurological disorders. However, the high frequency of the waves used in DBS can interfere with electrical recording devices (e.g., electrocardiogram, electroencephalogram, cardiac monitor), creating artifacts that hinder their interpretation. The compatibility of DBS with these devices varies and depends on factors such as the underlying disease and the configuration of the neurostimulator. In emergencies where obtaining an electrocardiogram is crucial, the need for more consensus on reducing electrical artifacts in patients with DBS becomes a significant challenge. Various strategies have been proposed to attenuate the artifact generated by DBS, such as changing the DBS configuration from monopolar to bipolar, temporarily deactivating DBS during electrocardiographic recording, applying frequency filters both lower and higher than those used by DBS, and using non-standard leads. However, the inexperience of medical personnel, variability in DBS models, or the lack of a controller at the time of approach limit the application of these strategies. Current evidence on their reproducibility and efficacy is limited. Due to the growing elderly population and the rising utilization of DBS, it is imperative to create electrocardiographic methods that are easily accessible and reproducible for general physicians and emergency services.

Long-Term Outcomes of Pharmacoinvasive Strategy Versus Primary Percutaneous Coronary Intervention in ST-Elevation Myocardial Infarction: A Study from Mexico City.

Although primary percutaneous coronary intervention (pPCI) is the treatment of choice in ST-elevation myocardial infarction (STEMI), challenges may arise in accessing this intervention for certain geodemographic groups. Pharmacoinvasive strategy (PIs) has demonstrated comparable outcomes when delays in pPCI are anticipated, but real-world data on long-term outcomes are limited. The aim of the present study was to compare long-term outcomes among real-world patients with STEMI who underwent either PIs or pPCI. This was a prospective registry including patients with STEMI who received reperfusion during the first 12 hours from symptom onset. The primary objective was cardiovascular mortality at 12 months according to the reperfusion strategy (pPCI vs PIs) and major cardiovascular events (cardiogenic shock, recurrent myocardial infarction, and congestive heart failure), and Bleeding Academic Research Consortium type 3 to 5 bleeding events were also evaluated. A total of 799 patients with STEMI were included; 49.1% underwent pPCI and 50.9% received PIs. Patients in the PIs group presented with more heart failure on admission (Killip-Kimbal >I 48.1 vs 39.7, p = 0.02) and had a lower proportion of pre-existing heart failure (0.2% vs 1.8%, p = 0.02) and atrial fibrillation (0.25% vs 1.2%, p = 0.02). No statistically significant difference was observed in cardiovascular mortality at the 12-month follow-up (hazard ratio for PIs 0.74, 95% confidence interval 0.42 to 1.30, log-rank p = 0.30) according to the reperfusion strategy used. The composite of major cardiovascular events (hazard ratio for PIs 0.98, 95% confidence interval 0.75 to 1.29, p = 0.92) and Bleeding Academic Research Consortium type 3 to 5 bleeding rates were also comparable. A low socioeconomic status, Killip-Kimball >2, age >60 years, and admission creatinine >2.0 mg/100 ml were predictors of the composite end point after multivariate analysis. In conclusion, this prospective real-world registry provides additional support that long-term major cardiovascular outcomes and bleeding are not different between patients who underwent PIs versus primary PCI.

Real-World Evaluation of a Pharmacoinvasive Strategy for STEMI in Latin America: A Cost-Effective Approach with Short-Term Benefits.

Purpose: While pharmacoinvasive strategy (PI) is a safe and effective approach whenever access to primary percutaneous intervention (pPCI) is limited, data on each strategy's economic cost and impact on in-hospital stay are scarce. The objective is to compare the cost-effectiveness of a PI with that of pPCI for the treatment of ST-elevation myocardial infarction (STEMI) in a Latin-American country. Patients and Methods: A total of 1747 patients were included, of whom 470 (26.9%) received PI, 433 (24.7%) pPCI, and 844 (48.3%) NR. The study's primary outcome was the incremental cost-effectiveness ratio (ICER) for PI compared with those for pPCI and non-reperfused (NR), calculated for 30-day major cardiovascular events (MACE), 30-day mortality, and length of stay. Results: For PI, the ICER estimates for MACE showed a decrease of $-35.81/per 1% (95 confidence interval, -114.73 to 64.81) compared with pPCI and a decrease of $-271.60/per 1% (95% CI, -1086.10 to -144.93) compared with NR. Also, in mortality, PI had an ICER decrease of $-129.50 (95% CI, -810.57, 455.06) compared to pPCI and $-165.27 (-224.06, -123.52) with NR. Finally, length of stay had an ICER reduction of -765.99 (-4020.68, 3141.65) and -283.40 (-304.95, -252.76) compared to pPCI and NR, respectively. Conclusion: The findings of this study suggest that PI may be a more efficient treatment approach for STEMI in regions where access to pPCI is limited or where patient and system delays are expected.

Analysis of immortal-time effect in post-infarction ventricular septal defect.

Introduction: Time-fixed analyses have traditionally been utilized to examine outcomes in post-infarction ventricular septal defect (VSD). The aims of this study were to: (1) analyze the relationship between VSD closure/non-closure and mortality; (2) assess the presence of immortal-time bias. Material and methods: In this retrospective cohort study, patients with ST-elevation myocardial infarction (STEMI) complicated by VSD. Time-fixed and time-dependent Cox regression methodologies were employed. Results: The study included 80 patients: surgical closure (n = 26), transcatheter closure (n = 20), or conservative management alone (n = 34). At presentation, patients without VSD closure exhibited high-risk clinical characteristics, had the shortest median time intervals from STEMI onset to VSD development (4.0, 4.0, and 2.0 days, respectively; P = 0.03) and from STEMI symptom onset to hospital arrival (6.0, 5.0, and 0.8 days, respectively; P < 0.0001). The median time from STEMI onset to closure was 22.0 days (P = 0.14). In-hospital mortality rate was higher among patients who did not undergo defect closure (50%, 35%, and 88.2%, respectively; P < 0.0001). Closure of the defect using a fixed-time method was associated with lower in-hospital mortality (HR = 0.13, 95% CI 0.05-0.31, P < 0.0001, and HR 0.13, 95% CI 0.04-0.36, P < 0.0001, for surgery and transcatheter closure, respectively). However, when employing a time-varying method, this association was not observed (HR = 0.95, 95% CI 0.45-1.98, P = 0.90, and HR 0.88, 95% CI 0.41-1.87, P = 0.74, for surgery and transcatheter closure, respectively). These findings suggest the presence of an immortal-time bias. Conclusions: This study highlights that using a fixed-time analytic approach in post-infarction VSD can result in immortal-time bias. Researchers should consider employing time-dependent methodologies.

Invasive Phenoprofiling of Acute-Myocardial-Infarction-Related Cardiogenic Shock.

BACKGROUND: Studies had previously identified three cardiogenic shock (CS) phenotypes (cardiac-only, cardiorenal, and cardiometabolic). Therefore, we aimed to understand better the hemodynamic profiles of these phenotypes in acute myocardial infarction-CS (AMI-CS) using pulmonary artery catheter (PAC) data to better understand the AMI-CS heterogeneity. METHODS: We analyzed the PAC data of 309 patients with AMI-CS. The patients were classified by SCAI shock stage, congestion profile, and phenotype. In addition, 24 h hemodynamic PAC data were obtained. RESULTS: We identified three AMI-CS phenotypes: cardiac-only (43.7%), cardiorenal (32.0%), and cardiometabolic (24.3%). The cardiometabolic phenotype had the highest mortality rate (70.7%), followed by the cardiorenal (52.5%) and cardiac-only (33.3%) phenotypes, with significant differences (p < 0.001). Right atrial pressure (p = 0.001) and pulmonary capillary wedge pressure (p = 0.01) were higher in the cardiometabolic and cardiorenal phenotypes. Cardiac output, index, power, power index, and cardiac power index normalized by right atrial pressure and left-ventricular stroke work index were lower in the cardiorenal and cardiometabolic than in the cardiac-only phenotypes. We found a hazard ratio (HR) of 2.1 for the cardiorenal and 3.3 for cardiometabolic versus the cardiac-only phenotypes (p < 0.001). Also, multi-organ failure, acute kidney injury, and ventricular tachycardia/fibrillation had a significant HR. Multivariate analysis revealed that CS phenotypes retained significance (p < 0.001) when adjusted for the Society for Cardiovascular Angiography & Interventions score (p = 0.011) and ∆congestion (p = 0.028). These scores independently predicted mortality. CONCLUSIONS: Accurate patient prognosis and treatment strategies are crucial, and phenotyping in AMI-CS can aid in this effort. PAC profiling can provide valuable prognostic information and help design new trials involving AMI-CS.

COMPARISON OF THE PREDICTIVE PERFORMANCE OF CARDIOGENIC SHOCK SCORES IN A REAL-WORLD LATIN AMERICA COUNTRY.

ABSTRACT: Background : Mortality in cardiogenic shock (CS) is up to 40%, and although risk scores have been proposed to stratify and assess mortality in CS, they have been shown to have inconsistent performance. The purpose was to compare CS prognostic scores and describe their performance in a real-world Latin American country. Methods : We included 872 patients with CS. The Society for Cardiovascular Angiography and Interventions (SCAI), CARDSHOCK, IABP-Shock II, Cardiogenic Shock Score, age-lactate-creatinine score, Get-With-The-Guidelines Heart Failure score, and Acute Decompensated Heart Failure National Registry scores were calculated. Decision curve analyses were performed to evaluate the net benefit of the different scoring systems. Logistic and Cox regression analyses were applied to construct area under the curve (AUC) statistics, this last one against time using the Inverse Probability of Censoring Weighting method, for in-hospital mortality prediction. Results: When logistic regression was applied, the scores had a moderate-good performance in the overall cohort that was higher AUC in the CARDSHOCK ( c = 0.666). In acute myocardial infarction-related CS (AMI-CS), CARDSHOCK still is the highest AUC (0.68). In non-AMI-CS only SCAI (0.668), CARDSHOCK (0.533), and IABP-SHOCK II (0.636) had statistically significant values. When analyzed over time, significant differences arose in the AUC, suggesting that a time-sensitive component influenced the prediction of mortality. The highest AUC was for the CARDSHOCK score (0.658), followed by SCAI (0.622). In AMI-CS-related, the highest AUC was for the CARDSHOCK score (0.671). In non-AMI-CS, SCAI was the best (0.642). Conclusions : Clinical scores show a time-sensitive AUC, suggesting that performance could be influenced by time and the type of CS. Understanding the temporal influence on the scores could provide a better prediction and be a valuable tool in CS.

Dynamic Invasive Hemodynamic Congestion Profile Impacts Acute Myocardial Infarction Complicated by Cardiogenic Shock Outcomes: A Real-World Single-Center Study.

BACKGROUND: Cardiogenic shock (CS) commonly complicates the management of acute myocardial infarction (AMI), and it results in high mortality rates. Pulmonary artery catheter (PAC) monitoring can be valuable for personalizing critical-care interventions. We hypothesized that patients with AMI-CS experiencing persistent congestion measures during the first 24 hours of the PAC installment would exhibit worse in-hospital survival rates. METHODS AND RESULTS: We studied 295 patients with AMI-CS between January 2006 and December 2021. The first 24-hour PAC-derived hemodynamic measures were divided by the congestion profiling and the proposed 2022 Cardiovascular Angiography and Interventions (SCAI) classification. Biventricular congestion was the most common profile and was associated with the highest patient mortality rates at all time points (mean 56.6%). A persistent congestive profile was associated with increased mortality rates (hazard ratio [HR] = 1.85; P = 0.002) compared with patients who achieved decongestive profiles. Patients with SCAI stages D/E had higher levels of right atrial pressure (RAP): 14-15 mmHg) and pulmonary capillary wedge pressure (PCWP): 18-20 mmHg) compared with stage C (RAP, 10-11 mmHg, mean difference 3-5 mmHg; P < 0.001; PCWP 14-17 mmHg; mean difference 1.56-4 mmHg; P = 0.011). In SCAI stages D/E, the pulmonary artery pulsatility index (0.8-1.19) was lower than in those with grade C (1.29-1.63; mean difference 0.21-0.73; P < 0.001). CONCLUSIONS: Continuous congestion profiling using the SCAI classification matched the grade of hemodynamic severity and the increased risk of in-hospital death. Early decongestion appears to be an important prognostic and therapeutic goal in patients with AMI-CS and warrants further study.

Application of the SCAI classification to admission of patients with cardiogenic shock: Analysis of a tertiary care center in a middle-income country.

AIMS: The Society of Cardiovascular Angiography and Interventions (SCAI) shock stages have been applied and validated in high-income countries with access to advanced therapies. We applied the SCAI scheme at the time of admission in order to improve the risk stratification for 30-day mortality in a retrospective cohort of patients with STEMI in a middle-income country hospital at admission. METHODS: This is a retrospective cohort study, we analyzed 7,143 ST-segment elevation myocardial infarction (STEMI) patients. At admission, patients were stratified by the SCAI shock stages. Multivariate analysis was used to assess the association between SCAI shock stages to 30-day mortality. RESULTS: The distribution of the patients across SCAI shock stages was 82.2%, 9.3%, 1.2%, 1.5%, and 0.8% to A, B, C, D, and E, respectively. Patients with SCAI stages C, D, and E were more likely to have high-risk features. There was a stepwise significant increase in unadjusted 30-day mortality across the SCAI shock stages (6.3%, 8.4%, 62.4%, 75.2% and 88.3% for A, B, C, D and E, respectively; P < 0.0001, C-statistic, 0.64). A trend toward a lower 30-day survival probability was observed in the patients with advanced CS (30.3, 15.4%, and 8.3%, SCAI shock stages C, D, and E, respectively, Log-rank P-value <0.0001). After multivariable adjustment, SCAI shock stages C, D, and E were independently associated with an increased risk of 30-day death (hazard ratio 1.42 [P = 0.02], 2.30 [P<0.0001], and 3.44 [P<0.0001], respectively). CONCLUSION: The SCAI shock stages applied in patients con STEMI at the time of admission, is a useful tool for risk stratification in patients across the full spectrum of CS and is a predictor of 30-day mortality.

[Los niveles de mediadores prorresolutivos no corresponden con los de mediadores inflamatorios en enfermedades isquémicas coronarias].

BACKGROUND: Inflammation can be grouped into three phases: proinflammatory, anti-inflammatory, and resolution. The latter, mainly attributed to lipid mediators, is the most recently described, and has been studied little in coronary ischemic diseases. OBJECTIVE: To evaluate 1) if acute coronary syndromes (ACS) manifest different circulating levels of resolution mediators compared with stable angina (SA); 2) if their concentrations are related to those of pro and anti-inflammatory mediators; and 3) if such concentrations are associated with the severity of the disease and the damage produced. METHOD: LTB4, RvD1, LXA4, ET-1, MMP-2, MMP-9, TIMP-1, IL-1ß, IL-6, IL-8 and IL-10 were measured in serum. The GRACE score was established as parameter of gravity, and LVEF as a damage parameter. RESULTS: Thirty patients with SA, 37 with NEST-ACS, 38 with STEMI, and 10 individuals with non-cardiogenic chest pain were included. Patients with coronary artery disease showed elevated levels of inflammatory cytokines and low levels of resolution mediators. CONCLUSIONS: The low resolution response even in patients with acute coronary disease suggests an inability to repair damage. Testing this hypothesis would have the potential to suggest new therapies for the management of chronic cardiovascular inflammation.

ANTECEDENTES: La inflamación puede agruparse en tres fases: proinflamatoria, antiinflamatoria y de resolución. Esta última, principalmente atribuida a mediadores lipídicos, es la de más reciente descripción y se ha estudiado poco en las enfermedades isquémicas coronarias. OBJETIVOS: Evaluar 1) si los síndromes coronarios agudos (SICA) manifiestan niveles circulantes distintos de mediadores de resolución comparados con la angina estable (AE); 2) si sus concentraciones se relacionan con las de mediadores proinflamatorios y antiinflamatorios; y 3) si dichas concentraciones se asocian con la gravedad de la enfermedad y el daño producido. MÉTODO: Se midieron LTB4, RvD1, LXA4, ET-1, MMP-2, MMP-9, TIMP-1, IL-1ß, IL-6, IL-8 e IL-10 en suero. Se establecieron la puntuación GRACE como parámetro de gravedad y la fracción de eyección del ventrículo izquierdo (FEVI) como parámetro de daño. RESULTADOS: Se incluyeron 30 pacientes con AE, 37 con SICA sin elevación del segmento ST (SICA-SEST), 38 con Infarto agudo del miocardio con elevación del segmetno ST(IAM-CEST) y 10 con dolor torácico no cardiogénico. Los pacientes con enfermedad coronaria mostraron niveles elevados de citocinas inflamatorias y bajos de mediadores de resolución. CONCLUSIONES: La escasa respuesta de resolución aun en pacientes con enfermedad coronaria aguda sugiere una incapacidad para reparar daños. Probar esta hipótesis tendría el potencial de sugerir nuevas terapias para el manejo de la inflamación cardiovascular crónica.

Serum of Patients with Psoriasis Modulates the Production of MMP-9 and TIMP-1 in Cells of Monocytic Lineage.

Psoriasis is triggered by several stimuli that share a systemic production of interferon (IFN)-γ and other inflammatory mediators, which are key to regulate the production of matrix metalloproteinase (MMP)-9 and its inhibitor (TIMP)-1 by cells of monocytic lineage. This study evaluates the effect of the sera of 55 patients with psoriasis and 41 non-psoriatic individuals on the production of MMP-9 and TIMP-1 in cultured monocytes from a single healthy blood donor and in U937 cells. The effect of IFN-γ stimulation was also evaluated. Serum and supernatant concentrations of IFN-γ, MMP-9, and TIMP-1 were measured by enzyme-linked immunoassays, and the MMP-9/TIMP-1 ratios were calculated. In monocytes, incubation with psoriasis' sera increased the production of MMP-9 and TIMP-1 in comparison with both baseline and monocytes incubated with non-psoriatic sera. Although the MMP-9/TIMP-1 ratio was significantly higher compared to the baseline, no differences between groups were observed. In contrast, IFN-γ stimulation in monocytes previously exposed to psoriasis' sera increased MMP-9 levels and decreased TIMP-1 levels, whereas stimulation in monocytes exposed to non-psoriatic sera did not further modify the levels of MMP-9 or TIMP-1. Consequently, the MMP-9/TIMP-1 ratio in cells exposed to psoriatic serum was significantly higher than in cells exposed to non-psoriatic sera (24.5 versus 16.7; P < 0.05). Similar results were observed in U937 cells. Therefore, our results suggest that soluble mediators in psoriatic sera may enhance the proteolytic phenotype of monocytes when stimulated with IFN-γ, which supports the existence of a primed state in the inflammatory cells of patients with psoriasis.

Acute coronary syndrome and acute kidney injury: role of inflammation in worsening renal function.

BACKGROUND: Acute Kidney Injury (AKI), a common complication of acute coronary syndromes (ACS), is associated with higher mortality and longer hospital stays. The role of cytokines and other mediators is unknown in AKI induced by an ACS (ACS-AKI), leading to several unanswered questions. The worsening of renal function is usually seen as a dichotomous phenomenon instead of a dynamic change, so evaluating changes of the renal function in time may provide valuable information in the ACS-AKI setting. The aim of this study was to explore inflammatory factors associated to de novo kidney injury induced by de novo cardiac injury secondary to ACS. METHODS: One hundred four consecutive patients with ACS were initially included on the time of admission to the Coronary Unit of the Instituto Nacional de Cardiología in Mexico City, from February to May 2016, before any invasive procedure, imaging study, diuretic or anti-platelet therapy. White blood count, hemoglobin, NT-ProBNP, troponin I, C-reactive protein, albumin, glucose, Na+, K+, blood urea nitrogen (BUN), total cholesterol, HDL, LDL, triglycerides, creatinine (Cr), endothelin-1 (ET-1), leukotriene-B4, matrix metalloproteinase-2 and -9, tissue inhibitor of metalloproteinases-1, resolvin-D1 (RvD1), lipoxin-A4 (LXA4), interleukin-1ß, -6, -8, and -10 were measured. We finally enrolled 78 patients, and subsequently we identified 15 patients with ACS-AKI. Correlations were obtained by a Spearman rank test. Low-rank regression, splines regressions, and also protein-protein/chemical interactions and pathways analyses networks were performed. RESULTS: Positive correlations of ΔCr were found with BUN, admission Cr, GRACE score, IL-1ß, IL-6, NT-ProBNP and age, and negative correlations with systolic blood pressure, mean-BP, diastolic-BP and LxA4. In the regression analyses IL-10 and RvD1 had positive non-linear associations with ΔCr. ET-1 had also a positive association. Significant non-linear associations were seen with NT-proBNP, admission Cr, BUN, Na+, K+, WBC, age, body mass index, GRACE, SBP, mean-BP and Hb. CONCLUSION: Inflammation and its components play an important role in the worsening of renal function in ACS. IL-10, ET-1, IL-1ß, TnI, RvD1 and LxA4 represent mediators that might be associated with ACS-AKI. IL-6, ET-1, NT-ProBNP might represent crossroads for several physiopathological pathways involved in "de novo cardiac injury leading to de novo kidney injury".

Las cardiopatías congénitas en el municipio Marianao, La Habana. Resultados de 10 años / Congenital cardiopathies in Marianao municipality, Havana: 10 years results

En este estudio se revisaron las 152 cardiopatías diagnos¬ticadas en el municipio Marianao entre los años 2002 y 2011, detectadas tanto prenatal como postnatalmente. Su frecuencia es similar a la reportada por otros autores. Al analizar la etiología hubo marcado predominio de las de origen multifactorial. Pocas mujeres refirieron consumo de ácido fólico preconcepcional. La mayoría de las mujeres que tuvieron hijos afectados fueron clasificadas como de bajo riesgo genético. En los casos de detección postnatal, que correspondieron a defectos leves, la edad materna se comportó de forma similar al resto de las gestantes que tu¬vieron hijos sanos, pero en los defectos severos que tuvie¬ron diagnóstico prenatal hubo marcada asociación con las edades reproductivas extremas…(AU)

Aneurisma de la aorta ascendente en el feto: reporte de un caso / Ascending aorta aneurysm in the fetus: a report of one case

Se presenta el caso de una gestante que en el ultrasonido de pesquisaje realizado en su área de salud se sospechó la presencia de dilatación aórtica fetal importante que fue confirmado en nuestro servicio por estudio ecocardiográfico realizado a las 23 semanas. La paciente recibió asesoramiento cardiogenético y posteriormente solicitó la interrupción del embarazo. El examen morfológico evidenció un aneurisma de la aorta al cual se encontraba asociado una coartación de la aorta circunscrita. Se analizan las posibles causas de dilatación aórtica como signo de sospecha de cardiopatías congénitas. Es el primer caso de su tipo reportado en Cuba(AU)

A case of pregnancy is reported to have a significant aortic dilatation detected by the ultrasonographic study during the second three months of pregnancy. The presence of an aneurysm in the ascendant aorta is confirmed in the study carried out at the 23 weeks of pregnancy. The patient decided not to continue the pregnancy after the cardio–genetic counselling. The necropsy exam evidenced the great aneurismatic dilatation as well as the presence of a coarctation of the associated aorta. The possible causes of aortic dilatation are commented as a sign of congenital heart disease. This is the first reported case in Cuba(AU)
