Persistent left superior vena cava as an incidental finding in the introduction of a transient pacemaker: A case report / Vena cava superior izquierda persistente como hallazgo incidental en la introducción de un marcapasos transitorio: informe de un caso

The persistent left superior vena cava is the most common venous anomaly in the systemic drainage in adults and tends to be asymptomatic. The persistent left superior vena cava causes rhythm disorders such as tachyarrhythmias or bradyarrhythmias. We report a case of persistent left superior vena cava diagnosed in a 53-year-old female patient admitted due to an acute coronary syndrome associated with unstable bradycardia. A transvenous peacemaker impressed the left atrium; therefore, a transthoracic echocardiogram was required to diagnose persistent left superior vena cava. The patient needed management with percutaneous intervention; she had an adequate evolution and subsequent discharge from the intensive care unit

La vena cava superior izquierda persistente es la anomalía venosa más frecuente en el drenaje sistémico en adultos; tiende a ser asintomática, pero causa trastornos del ritmo como taquiarritmias o bradiarritmias. Se presenta un caso de vena cava superior izquierda persistente diagnosticada en una paciente de 53 años hospitalizada por un síndrome coronario agudo asociado a bradicardia inestable. Un marcapasos transvenoso dejó una impresión en la aurícula izquierda, por lo que se requirió un ecocardiograma transtorácico para diagnosticar la vena cava superior izquierda persistente. La paciente necesitó una intervención percutánea con una adecuada evolución y se le dio el alta de la unidad de cuidados intensivos.

Ácidos grasos omega-3 y función endotelial en pacientes con síndrome coronario agudo / Omega-3 fatty acids and endothelial function in patients with acute coronary syndrome

Las enfermedades cardiovasculares son la principal causa de muerte a nivel mundial, manifestándose principalmente como enfermedad isquémica coronaria. El pronóstico y desenlace del Síndrome Coronario Agudo (SCA) depende en gran proporción de la disfunción endotelial asociado a este cuadro. Objetivo:Evaluar el efecto de los ácidos grasos omega­3, sobre la función endotelial en el Síndrome Coronario Agudo (SCA). Métodos: Se realizó estudio con 16 pacientes con síndrome coronario agudo (SCA) tratados con Omega-3 a dosis de 3 gramos/día+Terapia Convencional (O3+Tc) durante 30 días. Se les realizó a las 12 horas del ingreso y los a 30 días, perfil lipídico, proteína C reactiva ultrasensible (PCRus), Endotelina 1 (ET-1), y Péptido Natriurético cerebral (NTproBNP). Resultados: Durante 4 semanas de seguimiento, el uso de 3 gramos/día de ácidos grasos omega-3, añadido a la terapia convencional en el Síndrome Coronario Agudo, mostró una reducción significativa de la concentración plasmática de NTproBNP (p = 0,000), PCRus (p =0,000) y triglicéridos (p = 0,004). Conclusión: Tres gramos al día de ácidos grasos omega-3 contribuye a la reducción de la concentración plasmática de Triglicéridos y NTproBNP en pacientes con síndrome coronario agudo(AU)

Mainly as coronary ischemic disease. the prognosis and outcome of Acute Coronary Syndrome (ACS) depend largely on the endothelial dysfunction associated with this condition. Objective: To evaluate the effect of omega-3 fatty acids on endothelial function in Acute Coronary Syndrome (ACS). Method: A study was conducted with 16 patients with acute coronary syndrome (ACS) treated with Omega-3 at a dose of 3 grams/day+Conventional erapy (O3+Tc) for 30 days. Lipid profile, ultrasensitive C-reactive protein (usCRP), Endothelin 1 (ET-1), and Brain Natriuretic Peptide (NTproBNP) were performed 12 hours aer admission and 30 days later. Results: During 4 weeks of follow-up, the use of 3 grams/day of omega-3 fatty acids, added to conventional therapy in Acute Coronary Syndrome, showed a significant reduction in the plasma concentration of NTproBNP (p = 0.000), hsCRP (p =0.000) and Triglycerides (p = 0.004). Conclusion: three grams a day of omega-3 fatty acids contributes to the reduction of the plasmatic concentration of Triglycerides and NTproBNP in patients with acute coronary syndrome(AU)

Influence of Neuropeptide Y and Neuropeptide Y 2 Receptor Variants in Acute Coronary Syndrome

Abstract Background The neuropeptide Y (NPY) is one of the most abundant neurotransmitters in the nervous system. NPY acts as a potent stimulator of angiogenesis, inflammation, and adipogenesis, through the NPY 2 receptor (NPY2R). Changes in the NPY signaling pathway have been linked to Acute Coronary Syndrome (ACS). Objectives The purpose of this study is to determine the association between variants in the NPY and NPY2R genes, as well as the severity of acute coronary syndrome (ACS). Methods Approximately 221 ACS patients and 278 healthy controls were selected for this study. Four variants in NPY and two variants in NPY2R genes were genotyped using Taqman allelic discrimination and sequencing. The Chi-square and Fisher's exact tests were used to verify the genotype frequencies. The logistic regression analyses were used for the evaluation of the studied variables. Haplotype analysis was used to evaluate the linkage disequilibrium (LD) between the variants (p<0.05). Results An association of NPY c.20T>C variant was found with the ACS group when compared to the healthy group. In the analysis between variants and risk factors in the ACS group, NPY c.84G>A was associated with hypertension. The analysis between TIMI risk showed a significance for NPY c.20T>C between the low and intermediate/high TIMI risk groups. In the haplotype analysis, strong linkage disequilibrium (LD) was found between the variants NPY c.150G>A and NPY c.-485T>C. Conclusion The NPY c.20T>C variant appears to contribute to the development of ACS. The NPY2R c.-1116A>G variant may contribute to the early development of ACS and the NPY c.84G>A variant appears to contribute to the development of hypertension. In addition, the NPY c.20T>C is associated with a protective effect in ACS severity.

Validation of the Grace Risk Score to Predict In-Hospital and 6-Month Post-Discharge Mortality in Patients with Acute Coronary Syndrome

Abstract Background The wide range of clinical presentations of acute coronary syndrome (ACS) makes it indispensible to use tools for risk stratification and for appropriate risks management; thus, the use of prognosis scores is recommended in the immediat clinical decision-making. Objective To validate the Global Registry of Acute Coronary Events (GRACE) score as a predictor of in-hospital and 6-month post-discharge mortality in a population diagnosed with ACS. Methods This is a prospective cohort study of consecutive patients diagnosed with ACS between May and December 2018. GRACE scores were calculated, as well as their predictive value for in-hospital and 6-month post-discharge mortality. The validity of the model was assessed by two techniques: discriminative power using the area under the receiver operating characteristic curve (AUC) and goodness-of-fit, using the Hosmer-Lemeshow (HL) test, at the 5% level of significance. Results A total of 160 patients were included, mean age 64 (±10.9) years; of which 60% were men. The risk model showed to have satisfactory ability to predict both in-hospital mortality, with an area under the curve (AUC) of 0.76 (95% confidence interval [CI], 0.57-0.95; p = 0.014), and 6-month post-discharge mortality, with AUC of 0.78 (95%CI, 0.62-0.94), p = 0.002. The HL test indicated good-fit for both models of the GRACE score. Conclusion In this study, the GRACE risk score for predicting mortality was appropriately validated in patients with ACS, with good discriminative power and goodness-of-fit. The results suggest that the GRACE score is appropriate for clinical use in our setting.

Text Messages to Promote Secondary Prevention after Acute Coronary Syndrome (IMPACS trial)

Abstract Background Short message service (SMS) to promote healthcare improves the control of cardiovascular risk factors, but there is a lack of evidence in low and middle-income countries, particularly after acute coronary syndromes (ACS). Objective This study aims to evaluate whether the use of SMS increases risk factor control after hospital discharge for ACS. Methods IMPACS is a 2-arm randomized trial with 180 patients hospitalized due to ACS at a tertiary hospital in Brazil. Eligible patients were randomized (1:1) to an SMS intervention (G1) or standard care (G2) upon hospital discharge. The primary endpoint was set to achieve 4 or 5 points in a risk factor control score, consisting of a cluster of 5 modifiable risk factors: LDL-C <70mg/dL, blood pressure (BP) <140/90mmHg, regular exercise (≥5 days/week, 30 minutes/session), nonsmoker status, and body mass index (BMI) <25 kg/m2] at 6 months. Secondary outcomes were components of the primary outcome plus rehospitalization, cardiovascular death, and death from any cause. Results are designated as significant if p<0.05. Results From randomized patients, 147 were included in the final analysis. Mean age was 58 (51-64) years, 74% males. The primary outcome was achieved by 12 (16.2%) patients in G1 and 15 (20.8%) in G2 (OR=0.73, 95%CI 0.32-1.70, p=0.47). Secondary outcomes were also similar: LDL-C<70 mg/dl (p=0.33), BP<140/90 mmHg (p=0.32), non-smoker (p=0.74), regular exercise (p=0.97), BMI (p=0.71), and rehospitalization (p=0.06). Death from any cause occurred in three participants (2%), including one cardiovascular death in each group. Conclusion SMS intervention did not significantly improve cardiovascular risk factor control when compared to standard care in patients discharged after ACS in Brazil.

Association between Deep Subcutaneous Adipose Tissue Estimated by DAAT Index and Dietary Intake in Patients with Acute Coronary Syndrome

Abstract Background: Abdominal obesity has been associated with cardiovascular disease and may be modulated by dietary intake. The deep abdominal subcutaneous adipose tissue (dSAT) is a body fat compartment that can be estimated by using mathematical formulas. Objectives: To evaluate the association between dSAT estimated by the Deep-Abdominal-Adipose-Tissue (DAAT) index and dietary intake in patients with acute coronary syndrome (ACS). Methods: This is a cross-sectional study conducted with patients ≥ 18 years of age admitted to a tertiary hospital. Sociodemographic, clinical, and anthropometric (body weight [kg], height [m], waist, hip and neck circumferences [cm]) data were evaluated. A food frequency questionnaire was applied to identify each patient's nutrient intake. The DAAT index was calculated according to specific formulas for men and women. Possible association between food intake and the DAAT index was evaluated by multiple linear regression. The level of significance adopted was 0.05. Results: This study evaluated 138 patients, with a mean age of 61.2±10.8 years. Prevalence of obesity was 29.4% in men and 37.7% in women. Regarding waist circumference, 83% of the women showed values considered to be very high. The DAAT index was significantly higher in men when compared to woman (P < 0.0001) and proved to be positively correlated with proteins (r= 0.22, P= 0.01) and monounsaturated fatty acid (r= 0.18, P= 0.04) intake in the entire sample. After adjustment for sex, alcohol consumption, and levels of physical activity, the DAAT index was associated with the female sex (B= −129.84, P <0.001) and a sedentary lifestyle (B= 57.99, P <0.001). Conclusion: dSAT estimated by the DAAT index was not associated with dietary intake in patients with ACS.

Níveis mais Baixos de Fetuína-A Sérica estão Associados a um Maior Risco de Mortalidade em Dez Anos em Pacientes com Infarto do Miocárdio por Supradesnivelamento do Segmento ST / Lower Serum Fetuin-A Levels are Associated with a Higher Ten-Year Mortality Risk in Patients with ST-Elevation Myocardial Infarction

Resumo Fundamento A fetuína-A é um fator anti-inflamatório e anticalcificação envolvido no curso da doença arterial coronariana (DAC). Em alinhamento com essas funções, investigou-se a fetuína-A como marcador de risco cardiovascular em vários estudos. Porém, a associação entre a fetuína-A e o prognóstico dos pacientes com DAC ainda é controversa. Objetivos O presente estudo foi conduzido para identificar a associação entre o nível de fetuína-A sérica e doença cardiovascular (DCV) de longo prazo e a mortalidade global por infarto do agudo do miocárdio por supradesnivelamento do segmento ST (STEMI). Métodos Foram cadastrados no estudo cento e oitenta pacientes consecutivos com STEMI. A população do estudo foi dividida em subgrupos (mais baixo, ≤288 µg/ml; e mais alto, >288 µg/ml) de acordo com a mediana do nível de fetuína-A. Dados de acompanhamento clínico foram obtidos por contato telefônico anual com pacientes ou familiares. As causas das mortes também foram confirmadas pelo banco de dados de saúde nacional. P-valores bilaterais <0,05 foram considerados estatisticamente significativos. Resultados Durante um acompanhamento médio de 10 anos, foram registradas 71 mortes, das quais 62 foram devidas a DCV. Identificou-se um índice de mortalidade global e por DCV significativamente mais alto no grupo com nível de fetuína-A mais baixo que no grupo com nível de fetuína-A mais alto (44% versus 24%, p= 0,005; 48% versus 31%, p= 0,022, respectivamente). Nas análises de risco proporcionais por regressão de Cox, detectou-se que a fetuína-A era um preditor independente de mortalidade global e por DCV. Conclusões A baixa concentração de fetuína-A está associada ao prognóstico de longo prazo ruim pós-STEMI, independentemente de fatores de risco cardiovascular tradicionais. Nossos achados fortaleceram estudos prévios demonstrando consistentemente o papel determinante dos mediadores anti-inflamatórios em síndromes coronárias agudas.

Abstract Background Fetuin-A is an anti-inflammatory and anti-calcification factor involved in the course of coronary artery disease (CAD). In line with these functions, fetuin-A has been investigated as a cardiovascular risk marker in many studies. However, the association between fetuin-A and the prognosis of CAD patients is still controversial. Objectives The present study was conducted to identify the association between serum fetuin-A level and long-term cardiovascular disease (CVD) and all-cause mortality of ST-elevation acute myocardial infarction (STEMI). Methods One hundred eigthy consecutive patients with STEMI were enrolled in the study. The study population was divided into subgroups (lower, ≤288 µg/ml; and higher, >288 µg/ml) according to the median fetuin-A level. Clinical follow-up data was obtained by annual contact with the patients or family members by telephone. The causes of death were also confirmed by the national health database. Two-sided p-values<0.05 were considered statistically significant. Results During a median follow-up of 10 years, 71 deaths were recorded , 62 of whom died from CVD. Both CVD and all-cause mortality were found to be significantly higher in the lower fetuin-A group than the higher fetuin-A group (44% vs 24%, p= 0.005; 48% vs 31%, p= 0.022, respectively). In Cox regression proportional hazard analyses, fetuin-A was found to be an independent predictor of CVD and all-cause mortality. Conclusions Low fetuin-A concentration is associated with a poor long-term prognosis after STEMI, regardless of the traditional cardiovascular risk factors. Our findings have strengthened previous studies that consistently demonstrate the determining role of anti-inflammatory mediators in acute coronary syndromes.

ABSTRACT Objective: To analyze the incidence, risk factors, and associations of clinical outcomes for contrast-induced acute kidney injury (CI-AKI) in patients with acute coronary syndrome (ACS) after coronary angioplasty. Method: Prospective cohort of 182 patients followed for three months after undergoing angioplasty, from July 2020 to June 2021. The analyzed variables were sociodemographic, clinical, and those related to the procedure. Results: The incidence of CI-AKI was 35.7% (n = 65) and was associated with old age, diabetes mellitus, and chronic kidney disease (p = 0.004, p < 0.001, and p = 0.009, respectively). Out of the 17 patients who died within 90 days, 76.5% had CI-AKI (n = 13), the odds ratio between death and CI-AKI was approximately 7.2 times (95% confidence interval (CI), [2.41;26.36]; p = 0.001). The decrease of one unit in the patient's baseline hemoglobin showed a 6.5% increase for CI-AKI (95% CI, [−0.089; −0.040]; p < 0.0001). Conclusion: CI-AKI is prevalent in patients with ACS after angioplasty and is related to diabetes mellitus and chronic kidney disease, showing high mortality rates.

Multimorbidity in elderly patients with acute coronary syndrome: insights from BleeMACS registry / 中华心血管病杂志

Objective: To assess the prevalence, pattern and outcome of multimorbidity in elderly patients with acute coronary syndrome (ACS). Methods: Secondary analysis was performed based on the data from the BleeMACS registry, which was conducted between 2003 and 2014. We stratified elderly patients (≥65 years) according to their multimorbidity. Multimorbidity was defined as two or more chronic diseases in the same individual. Kaplan-Meier methods were used to estimate 1 year event rates for each endpoint, and comparisons between the study groups were performed using the log-rank test. The primary endpoint was net adverse clinical events (NACE), which is a composite of all-cause mortality, myocardial infarction, or bleeding. Results: Of 7 120 evaluable patients, 6 391 (89.8%) were with morbidity (1 594 with 1, 2 156 with 2, and 2 641 with ≥3 morbidity). Patients with morbidity were older, percent of female sex and non-ST-elevation acute coronary syndromes and implantation rate with drug-eluting stents and blood creatine level were higher compared to patients without morbidity. Compared with the patients without morbidity, the proportion of participants with oral anticoagulant increased in proportion to increased number of morbidities (5.8% vs. 6.4% with 1 morbidity, 7.3% with 2 morbidities, 9.0% with ≥3 morbidities, P trend<0.01) and the proportion of participants with clopidogrel prescription decreased in proportion to increased number of morbidity (91.9% vs. 89.7% with 1 morbidity, 87.9% with 2 morbidities, 88.6% with ≥3 morbidities, P trend = 0.01). During 1 year follow-up, compared with those with no morbidity, the hazard ratio (HR) and 95% confidence interval (CI) of risk of NACE for those with 1, 2, and ≥ 3 morbidities was 1.18 (0.86-1.64), 1.49 (1.10-2.02), and 2.74 (2.06-3.66), respectively (P < 0.01). Multimorbidity was not associated with an increased risk of bleeding of various organs (P>0.05). Conclusion: Multimorbidity is common in elderly patients with ACS. These patients might benefit from coordinated and integrated multimorbidity management by multidisciplinary teams.

Risk factors for potential drug-drug interactions of statins in patients with acute coronary syndrome

Abstract The aim of our study was to assess risk factors for potential drug-drug interactions (pDDIs) of statins across different phases of treatment of acute coronary syndrome (ACS) patients: from the point of first medical contact to the coronary angiography (first phase), after coronary angiography to the last day of hospitalization (second phase) and at discharge from hospital (third phase). This was a post hoc analysis of the data collected during the retrospective observational cohort study conducted at the Clinic for Cardiology of the Clinical Centre Kragujevac, Serbia. Patients prescribed statins were identified from the original study population: 156, 240 and 236 patients for the first, second and third phases, respectively. At least one statin pDDI was present in 113 (72.4%), 161 (67.1%) and 139 (58.9%) patients in the first, second and third phases, respectively. Heart failure, arrhythmias after ACS, CRP, triglycerides, length of hospitalization, number of prescribed drugs, antiarrhythmic drugs, and clopidogrel seem to increase the risk of statin pDDIs in at least one treatment phase. Physicians should be vigilant to the possibility of statin pDDIs in ACS patients who have factors that may increase their rate.
