RESUMEN
BACKGROUND: Atrial fibrillation (AF) is the most common complication after cardiac surgery. The pathogenesis of postoperative atrial fibrillation (POAF) is multifactorial and one of the known factors is inflammation. Platelet mass index (PMI) is an indicator of platelet activation and a better inflammatory marker than mean platelet volume (MPV). In this retrospective study, we investigated the relationship between POAF and PMI. METHODS: The study included 848 consecutive patients (655 male and 193 female) who had elective isolated coronary artery by-pass grafting (CABG) or combined CABG and valvular surgery. Platelet count and MPV were measured from preoperative blood samples to calculate PMI. Post-operative atrial fibrillation was defined as irregular and fibrillatory P waves occurring 48-96â¯h after cardiac surgery and lasting at least 30â¯s. The PMI values in patients who developed POAF were compared with those in patients who did not develop POAF. RESULTS: Patients who developed POAF had higher PMI values (2549.3⯱ 1077.1) when compared with patients in sinus rhythm (2248.1⯱ 683.4; pâ¯< 0.01). In multivariate regression analysis, age (OR: 1.05; 95% CI: 1.02-1.09; pâ¯= 0.01), left atrial diameter (OR: 1.05; 95% CI: 1.03-1.09; pâ¯= 0.02), hs-CRP (OR: 1.09; 95%CI: 1.05-1.13; pâ¯< 0.01), EuroSCORE II (OR: 1.27; 95% CI: 1.14-1.41; pâ¯< 0.01), and PMI (OR: 1.01; 95% CI: 1.001-1.02; pâ¯< 0.01) were independent predictors of POAF. In ROC analysis, PMIâ¯≥ 2286 predicted POAF development with a sensitivity of 69% and a specificity of 58% (AUC: 0.66; pâ¯< 0.01) CONCLUSION: A significant relationship was found between preoperatively calculated PMI and POAF. We showed that PMI may be used to predict patients who are at high risk of developing POAF.

OBJECTIVE: The aim of the present study was to investigate the association between the mean corrected thrombolysis in myocardial frame count and major adverse cardiovascular events in patients with the coronary slow-flow phenomenon. METHODS: A total of 98 patients with coronary slow-flow phenomenon who met inclusion cri- teria from 2015 to 2020 were retrospectively included in the analysis. The patients were ranked according to their mean corrected thrombolysis in myocardial frame count values and were divided into quartiles based on those. Group 1 consisted of patients who had a mean corrected thrombolysis in myocardial frame count value >36.68 (third quartile), while group 2 consisted of patients who had a mean corrected thrombolysis in myocardial frame count value ≤36.68 (first quartile+second quartile). Mortality and non-fatal cardiovascular complications were compared between the groups. RESULTS: Mean follow-up duration was 3.93 ± 1.50 years. Recurrent chest pain and major adverse cardiovascular events increased in group 1 compared to group 2 (P ≤ .001, P ≤ .001, respectively). Hypertension (odds ratio 2.627, P=.033), hyperlipidemia (odds ratio 2.469, P = .028) and mean corrected thrombolysis in myocardial frame count (odds ratio 1.106, P = .002) were independent predictors of recurrent chest pain according to Cox regression analysis. Although older age (odds ratio 1.125, P=.011), hypertension (odds ratio 6.081, P=.026), hyperlipidemia (odds ratio 12.308, P = 0.019), and mean corrected thrombolysis in myocardial frame count (odds ratio 1.476, P = .001) were found to be significantly related with major adverse cardiovascular events in patients with coronary slow-flow phenomenon, only mean corrected thrombolysis in myocardial frame count (odds ratio 1.161, P = .021) was an indepen- dent predictor of major adverse cardiovascular events in Cox regression analysis. CONCLUSION: Higher mean corrected thrombolysis in myocardial frame count could predict major adverse cardiovascular events in patients with the coronary slow-flow phenomenon.

BACKGROUND: Despite the high proportion of octogenarians with acute pulmonary embolism, there is little information indicating the optimal management strategy, mainly therapeutic measures, such as lytic therapy. OBJECTIVES: The number of elderly patients diagnosed with acute pulmonary embolism increases constantly. However, the role of thrombolytic treatment is not clearly defined among octogenarians. Our objective is to evaluate the effectiveness of lytic therapy in octogenarian patients diagnosed with pulmonary embolism. METHODS: One hundred and forty eight subjects (70.3% women, n=104) aged more than eighty years were included in the study. The patients were divided in two groups: thrombolytic versus non-thrombolytic treatment. In-hospital mortality rates and bleeding events were defined as study outcomes. P-value <0.05 was considered as statistical significance. RESULTS: In-hospital mortality decreased significantly in the thrombolytic group compared to the non-thrombolytic group (10.5% vs. 24.2% p=0.03). Minor bleeding events were more common in the arm that received thrombolytic treatment, but major hemorrhage did not differ between the groups (35.1% vs. 13.2%, p<0.01; 7% vs. 5.5% p=0.71, respectively). High PESI score (OR: 1.03 95%CI; 1.01-1.04 p<0.01), thrombolytic therapy (OR: 0.15 95%CI; 0.01-0.25, p< 0.01) and high troponin levels (OR: 1.20 95%CI; 1.01-1.43, p=0.03) were independently associated with in-hospital mortality rates in the multivariate regression analysis. CONCLUSION: Thrombolytic therapy was associated with reduced in-hospital mortality at the expense of increased overall bleeding complications in octogenarians.
FUNDAMENTO: Apesar da grande proporção de octogenários com embolia pulmonar aguda, há pouca informação indicando a estratégia de manejo ideal, especialmente medidas terapêuticas, como a terapia lítica. OBJETIVOS: O número de pacientes idosos diagnosticados com embolia pulmonar aguda aumenta constantemente. Porém, o papel do tratamento trombolítico não está claramente definido entre os octogenários. Nosso objetivo é avaliar a efetividade da terapia lítica em pacientes octogenários diagnosticados com embolia pulmonar. MÉTODOS: Cento e quarenta e oito indivíduos (70,3% de mulheres, n=104) com mais de 80 anos foram incluídos no estudo. Os pacientes foram divididos em dois grupos: tratamento trombolítico versus não-trombolítico. As taxas de mortalidade hospitalar e episódios de sangramento foram definidos como desfechos do estudo. Valor de p <0,05 foi considerado como estatisticamente significativo. RESULTADOS: A mortalidade hospitalar reduziu significativamente no grupo trombolítico em comparação ao não-trombolítico (10,5% vs. 24,2%; p=0,03). Episódios de sangramento menores foram mais comuns no braço que recebeu o tratamento trombolítico, mas grandes hemorragias não diferiram entre os grupos (35,1% vs. 13,2%, p<0,01; 7% vs. 5,5% p=0,71, respectivamente). O escore de PESI alto (OR: 1,03 IC95%; 1,01-1,04 p<0,01), a terapia trombolítica (OR: 0,15 IC95%; 0,01-0,25, p< 0,01) e níveis altos de troponina (OR: 1,20 IC95%; 1,01-1,43, p=0,03) estiveram independentemente associados a taxas de mortalidade hospitalar na análise de regressão multivariada. CONCLUSÃO: A terapia trombolítica esteve associada à mortalidade hospitalar reduzida em detrimento do aumento geral das complicações de sangramento em octogenários.

OBJECTIVE: The effect of malnutrition in patients with ST segment elevation myocardial infarction (STEMI) is not fully understood. In this study, we tried to investigate the prognostic consequence of the Controlling Nutritional Status (CONUT) score in patients with STEMI. METHODS: In this study, we evaluated the CONUT scores of 1,028 patients with STEMI and examined its relationship with major adverse cardiovascular events (MACE) (all-cause mortality, myocardial reinfarction, and vessel revascularization) during a period of 19.9±10.3 months. Patients with CONUT score ≥5 were defined as severely malnourished. Predictors of MACE were assessed by Cox regression analysis, and p<0.05 was considered to indicate statistical significance. RESULTS: MACE was observed in a total of 147 (14.3%) patients. MACE was more frequent in the group with a higher CONUT score (33.3% vs. 10.9%, p<0.001). CONUT score ≥5 was an independent predictor of MACE in the Cox regression analysis (hazard ratio=2.50, 95% confidence interval: 1.61-3.90, p<0.001). Low ejection fraction, Killip class ≥3 at presentation, thrombolysis in myocardial infarction flow grade <3 after intervention, left main artery involvement, and low hemoglobin levels were other independent predictors of MACE in the long-term follow-up. Kaplan-Meier curves showed decreased MACE free survival rates in the high CONUT score group at a mean 19.9±10.3 months' follow-up duration (log-rank p<0.01). CONCLUSION: Malnutrition was strongly associated with poor outcomes in patients with STEMI treated using primary percutaneous coronary intervention.

OBJECTIVES: Patients with postoperative atrial fibrillation (POAF) have increased risk of both short- and long-term mortality and morbidity; therefore, prediction of POAF is crucial in the preoperative period of the patients undergoing coronary artery bypass graft surgery. Electrocardiography (ECG) is the simplest and cost-effective tool in the preoperative workup of the patients for the prediction of POAF. A newly defined ECG parameter P wave peak time (PWPT) has been shown as a marker of atrial fibrillation development in non-surgical patients and we investigated its role in patients undergoing cardiac surgery. METHOD: A total of 327 patients undergoing isolated or combined cardiac surgery were involved and the primary endpoint was defined as the development of POAF. The study population was divided into two groups based on the presence or absence of POAF. Groups were compared for both standard P wave parameters and for PWPT on surface ECG. The predictors of POAF were assessed by multivariate regression analysis. RESULTS: The frequency of POAF was 20.4% (n = 67). P wave peak time in leads D2 (65.1 ± 11.8 vs 57.2 ± 10, p < 0.01) and V1 (57.8 ± 18 vs 44.8 ± 12.3, p < 0.01) were longer in patients with POAF. In multivariate regression analysis, PWPT in leads DII and V1 were independent predictors of POAF (OR: 1.11, 95%CI: 1.02-1.21, p = 0.01, OR: 1.06, 95%CI: 1.00-1.13, p = 0.03 respectively). CONCLUSION: PWPT in leads DII and V1 can predict the development of POAF in patients undergoing cardiac surgery.

OBJECTIVE: Apelin is a novel adipocytokine with a significant role in ischemia/reperfusion injury that is synthesized and secreted in myocardial cells and coronary endothelium. There is debate on its value for the diagnosis and prognosis of myocardial infarction. We aimed to investigate plasma apelin level in patients with acute ST segment elevation (STEMI) and non-ST segment elevation (NSTEMI) myocardial infarction and its relationship with left ventricular function and prognostic parameters. METHODS: Forty-one patients with STEMI, 21 patients with NSTEMI and 10 patients as control group with normal coronary angiograms were included. Plasma apelin level at presentation was investigated regarding its relationship with other diagnostic and prognostic parameters. RESULTS: Apelin level was significantly higher in acute myocardial infarction (0.31 ± 0.56 ng/mL) compared to control group (0.08 ± 0.05 ng/mL) (p < 0.01). Likewise, it was found to be significantly higher in STEMI group (0.45 ± 0.73 ng/mL) compared to control group (0.08 ± 0.05 ng/mL) (p < 0.01). Although apelin was higher in NSTEMI group (0.13 ± 0.10 ng/mL) compared to control group (0.08 ± 0.05 ng/mL), this difference was not statistically significant (p > 0.05). No correlation was found between apelin and NT-proBNP, hsCRP, troponin, ejection fraction (EF) and Killip score (p > 0.05). A positive correlation was found between apelin and TIMI, GRACE and Gensini scores (p < 0.05). Only GRACE score was found to be correlated with apelin in MI groups. CONCLUSION: Apelin level was found to be high in acute myocardial infarction. With its inotropic and vasodilator effects, apelin was thought to have a protective role against severe ischemia.
RESUMEN
BACKGROUND: Digoxin treatment has come under scrutiny in recent years after reports from several studies that it is associated with increased mortality in patients with atrial fibrillation (AF). The clinical effects of digoxin on mortality were closely related to serum digoxin concentrations (SDC) in these studies. In the present work, we evaluated the role of the SAMe-TT2R2 and modified SAMe-TT2R2 scores in predicting the therapeutic range of digoxin therapy. METHODS: Medical records from our institution were screened for patients who were under digoxin treatment between 2008 and 2018. A total of 2418 patients for whom SDC were recorded were included in the study. An SDC of <0.5 or >1.2â¯ng/ml was defined as being out of the therapeutic range (oTR). RESULTS: In multivariable regression analyses, abnormal body mass index (odds ratio [OR]: 1.59, 95% confidence interval [CI]: 1.29-1.95, pâ¯< 0.01), white blood cell count (OR: 1.12, 95% CI: 1.01-1.27, pâ¯< 0.01), and the modified SAMe-TT2R2 score (OR: 4.19 95% CI: 3.71-4.72, pâ¯< 0.01) were determined to be independent predictors of oTR. A modified SAMe-TT2R2 score greater than 3 predicted oTR with a sensitivity of 86% and a specificity of 65% (AUC: 0.825, pâ¯< 0.01). CONCLUSION: Digoxin is still widely used in the treatment of heart failure and AF despite concerns about the increased risk of mortality when levels are oTR. In the present study, the modified SAMe-TT2R2 score was found to be an independent predictor of oTR. This score may aid clinicians in identifying patients who are more likely to benefit from digoxin therapy.

BACKGROUND: Right ventricular stroke work index is a useful but invasively measured parameter that can be used to predict right heart failure following continuous-flow left ventricular assist device implantation. Right ventricular contraction pressure index is a novel parameter that was developed to measure right ventricular stroke work index with echocardiography. We aimed to investigate the clinical usefulness of right ventricular contraction pressure index to predict short-term mortality and right heart failure in patients who underwent continuous-flow left ventricular assist device implantation. METHODS: A total of 49 patients who participated in institutional advanced heart failure registry and underwent continuous-flow left ventricular assist device implantation with a bridge-to-candidacy indication were analyzed retrospectively. Right ventricular contraction pressure index was calculated using offline measurements. Demographic, clinical and outcome data were obtained from the registry data. Patients were grouped according to right ventricular contraction pressure index quartiles. RESULTS: Patients within the lowest right ventricular contraction pressure index quartile had a trend toward higher short-term mortality (46.2%, p = 0.056) and combined short-term mortality and definitive right heart failure (53.8%, p = 0.054) at 15th day postoperatively. Similarly, short-term survival or survival free of definite right heart failure were significantly lower in the lowest right ventricular contraction pressure index quartile (log-rank p = 0.045 and log-rank p = 0.03, respectively). In a proportional hazards model that included echocardiographic parameters, right ventricular contraction pressure index was an independent predictor for short-term mortality (odds ratio: 6.777, 95% confidence interval: 1.118-41.098, p = 0.037), but not for combined short-term mortality and definite right heart failure. No such associations were found for long-term mortality. Right ventricular contraction pressure index had a statistically significant correlation with invasively measured pulmonary capillary wedge pressure, pulmonary vascular resistance, mean pulmonary pressure, and right ventricular stroke work index. CONCLUSION: Right ventricular contraction pressure index was found as a useful parameter for determining short-term postoperative mortality in patients undergoing continuous-flow left ventricular assist device implantation.

We retrospectively analyzed short- and long-term outcomes of patients who received bailout tirofiban during primary percutaneous intervention (pPCI). A total of 2681patients who underwent pPCI between 2009 and 2014 were analyzed; 1331 (49.6%) out of 2681 patients received bailout tirofiban. Using propensity score matching, 2100 patients (1050 patient received bail-out tirofiban) with similar preprocedural characteristics were identified. Patients who received bailout tirofiban had a significantly higher incidence of acute stent thrombosis, myocardial infarction, and major cardiac or cerebrovascular events during the in-hospital period. There were numerically fewer deaths in the bailout tirofiban group in the unmatched cohort (1.7% vs 2.5%, P = .118). In the matched cohort, in-hospital mortality was significantly lower (1.1% vs 2.4%, P = .03), and survival at 12 and 60 months were higher (96.9% vs 95.2%, P = .056 for 12 months and 95.1% vs 92.0%, P = .01 for 60 months) in the bailout tirofiban group. After multivariate adjustment, bailout tirofiban was associated with a lower mortality at 12 months (odds ratio [OR]: 0.554, 95% confidence interval [CI], 0.349-0.880, P = .012) and 60 months (OR: 0.595, 95% CI, 0.413-0.859, P = .006). In conclusion, bailout tirofiban strategy during pPCI is associated with a lower short- and long-term mortality, although in-hospital complications were more frequent.

OBJECTIVE: The aim of the present study was to evaluate in-hospital and long-term outcomes of ST-segment elevation myocardial infarction (STEMI) survivors who experienced out-of-hospital cardiac arrest (OHCA) and underwent primary percutaneous coronary intervention (PCI) at a high-volume center within the STEMI network. METHODS: The records of 2681 consecutive STEMI patients who underwent primary PCI between January 2009 and December 2014 at a single center in the STEMI network were retrospectively analyzed. Patients with STEMI complicated by OHCA were compared with a reference group of STEMI patients who did not experience OHCA. RESULTS: Compared with STEMI survivors without OHCA (n=2587, 96.5%), the frequency of anterior myocardial infarction, duration of hospitalization, rate of in-hospital major adverse cardiovascular and cerebrovascular events, and the incidence of ischemic cerebrovascular disease and major bleeding during in-hospital follow-up were significantly greater in those with OHCA (n=94, 3.5%). The distribution of age and gender was similar between the 2 groups. The primary PCI success rate was high and was similar in both groups. In-hospital mortality was significantly higher (18.1% vs. 1.5%; p<0.001) and survival at the 12th and 60th months was lower (74.5% vs. 96.5%; p<0.001 and 71.3% vs. 93.7%; p<0.001) in STEMI survivors with OHCA. OHCA was an independent predictor for in-hospital mortality (Odds ratio [OR]: 3.413; 95% confidence interval [CI]: 1.534-7.597; p=0.003) and all-cause mortality at 60 months (OR: 3.285; 95% CI: 2.020-5.340; p<0.001). CONCLUSION: Mortality was high in patients with STEMI complicated by OHCA, even though PCI was performed with the same success rate seen in patients without OHCA.

OBJECTIVE: The present study is an investigation of the association between high on-treatment platelet reactivity to clopidogrel (HTPRC) and hepatosteatosis in patients who had elective stent implantation due to coronary artery disease. METHODS: A total of 190 consecutive patients who underwent an elective coronary stent implantation due to coronary artery disease were prospectively enrolled in the study. Eligible patients were given a 300 mg loading dose of clopidogrel before percutaneous coronary intervention. All of the patients underwent an ultrasound assessment for fatty liver. The patients were divided into 2 groups according to the detection of HTPRC: patients with HTPRC and patients without HTPRC. RESULTS: HTPRC was present in 54.2% (103 of 190 patients) of the total study population. The age and body mass index data were similar between the 2 groups. In all, 111 (58.6%) patients had hepatosteatosis. The HTPRC ratio was statistically higher in female patients (p=0.032). Hepatosteatosis was significantly greater in patients with HTPRC (p<0.001); 84 (81.6%) patients with HTPRC had hepatosteatosis (p=0.001). There was also a statistically significant association between the hepatosteatosis grade and HTPRC (p<0.001). The percentage of HTPRC was greater in patients with ≥grade 2 hepatosteatosis than grade 1 (p<0.001). Logistic regression analysis indicated that hepatosteatosis (odds ratio: 9.403, 95% confidence interval: 4.519-19.566; p<0.001), fasting blood glucose, and hypertension were independent predictors of HTPRC. CONCLUSION: To the best of our knowledge, this is the first study to demonstrate a relationship between hepatosteatosis and HTPRC.

Masses on the interatrial septum are usually caused by myxomas or thrombi within a patent foramen ovale. We report a 53-year-old male patient with a hollow mass within the left atrium that was incidentally found during a routine transthoracic echocardiography. Further investigation of the mass with transesophageal two- and three-dimensional echocardiography has revealed that the mass was a localized aneurysm of a patent foramen ovale tunnel. While aneurysms of interatrial septum are relatively common in normal population, to the best of our knowledge, present case is the first report of a localized aneursym of a patent foramen ovale tunnel.

BACKGROUND: Temporary transvenous pacemaker implantation is an important and critical procedure for emergency physicians. Traditionally, temporary pacemakers are inserted by electrocardiography (ECG) guidance in the emergency department because fluoroscopy at the bedside in an unstable patient can be limited by time and equipment availability. However, in the presence of atrial septal defect, ventricular septal defect, and patent foramen ovale, the pacemaker lead can be implanted inadvertently into the left ventricle or directly into the coronary sinus instead of right ventricle. Regular pacemaker rhythm can be achieved despite inadvertent implantation of the pacemaker lead into the left ventricle, leading to ignorance of the possibility of lead malposition. CASE REPORT: A 65-year-old female patient with hemodynamic instability and complete atrioventricular block underwent temporary pacemaker implantation via right jugular vein with ECG guidance at the emergency department. Approximately 12 h after implantation, it was noticed that the ECG revealed right bundle branch block (RBBB)-type paced QRS complexes. Diagnostic workup revealed that the lead was inadvertently located in the left ventricular apex. This case illustrates the importance of careful scrutiny of the 12-lead ECG and imaging clues in identifying lead malposition in the emergency department. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Because inadvertent left ventricle endocardial pacing carries a high risk for systemic embolization, it is important to determine whether an RBBB pattern induced by ventricular pacing is the result of a malpositioned lead or uncomplicated transvenous right ventricular pacing.

Artifacts are by-products of ultrasound imaging that may cause confusion or misdiagnosis if not interpreted correctly. There are, however, several disorders where a specific pattern of artifacts can aid in diagnosis, especially when the object in question cannot be visualized directly. In this manuscript, we report two patients with reverberation and shadow artifacts originating from the housing and the propeller of a continuous-flow intra-pericardial left ventricular assist device. Visualization of the artifacts required modified transthoracic views, so these artifacts should not pose a diagnostic challenge during a routine echocardiographic evaluation. However, we consider that shadow artifacts might be used to evaluate pump thrombosis in patients with intra-pericardial assist devices.
