RESUMEN

Objective: Despite improvements in the technology of catheter ablation of atrial fibrillation (AF), recurrences are still a major problem, even after a successful procedure. The uric acid/albumin ratio (UAR), which is an inexpensive and simple laboratory parameter, has recently been introduced in the literature as a predictor of adverse cardiovascular events. Hence, we aimed to investigate the relationship between the UAR and AF recurrence after catheter ablation. Methods: A total of 170 patients who underwent successful catheter ablation for AF were included. The primary outcome was the late recurrence after treatment. The recurrence (+) and recurrence (−) groups were compared for clinical, laboratory and procedural characteristics as well as the predictors of recurrence assessed by regression analysis. Results: In our study population, 53 (26%) patients developed AF recurrence after catheter ablation. Mean UAR was higher in the recurrence (+) group compared to recurrence (−) group (2.4 ± 0.9 vs. 1.8 ± 0.7, p < 0.01). In multivariable regression analysis, left atrial diameter (HR: 1.08, 95% CI: 1.01−1.16, p = 0.01) and UAR (HR:1.36, 95% CI: 1.06−1.75, p = 0.01) were found to be independent predictors of recurrence. In ROC analysis, the UAR > 1.67 predicted recurrence with a sensitivity of 77% and a specificity of 57% (AUC 0.68, p < 0.01). Conclusion: For the first time in the literature, the UAR were found to be correlated independently with AF recurrence after catheter ablation.

RESUMEN

BACKGROUND: Although aortic valve replacement (AVR) when successfully performed boasts low mortality rates in selected patients, prosthesis-patient mismatch (PPM) can be found in the majority of these individuals. Limited research is available supporting the benefit of two-dimensional speckle tracking echocardiography (2D-STE) in patients with severe PPM. This study sought to assess myocardial strain using 2D-STE to determine the relationship between subclinical left ventricular (LV) dysfunction and aortic PPM in patients undergoing AVR with preserved LV ejection fraction. MATERIAL AND METHODS: We retrospectively examined all consecutive patients with isolated AVR who presented to our center from 2005 to 2018. The data of 1086 patients were analyzed. Severe PPM was defined as an indexed effective orifice area of 0.65 cm2/m2 or less. As a result of the detailed assessment, 54 patients meeting the eligibility criteria were included in the study. Baseline data were collected and compared between the two groups of patients with severe PPM (n = 27) and those with normofunctional aortic prosthesis valve as a control group (n = 27). All patients underwent baseline echocardiography. Global longitudinal strain (GLS) and global circumferential strain (GCS) were evaluated by 2D-STE. RESULTS: When compared with controls, patients with severe PPM had significantly decreased GLS (18.6 ± 2.9 vs. 21.4 ± 2.1; p < 0.01) and GCS (17.2 ± 3.6 vs. 21.7 ± 2.1; p < 0.01) values. CONCLUSION: In addition to standard clinical and echocardiographic parameters, GLS and GCS suggest subclinical dysfunction and have incremental value in patients with severe PPM.

RESUMEN

BACKGROUND: An increase in short-term mortality can be found among older patients with hemodynamically stable acute pulmonary embolism (APE) who have signs of right ventricular (RV) dysfunction. AIMS: This study was designed to assess whether any difference exists among clinical, laboratory, electrocardiography and echocardiography parameters between older and younger patients diagnosed with APE. METHODS: The study sample included a total of 635 patients with confirmed APE who were divided into two groups of older (65 years and older) and younger (younger than 65 years) individuals. Comparisons were performed between these groups in terms of clinical, predisposing factors and laboratory, electrocardiographic and echocardiographic parameters. RESULTS: Analyses of 295 (46.4%) older and 340 (53.6%) younger patients diagnosed with APE were performed. Female sex, Pulmonary Embolism Severity Index score and baseline creatinine levels were higher in the older group. Also, the frequency of atrial fibrillation, RV outflow tract parasternal long-axis proximal diameter, RV end-diastolic diameter (RV-EDD) basal (apical four-chamber) and RV systolic pressure were significantly greater in older patients with APE. A total of 30 (4.7%) deaths were observed during the in-hospital period [21 (7.1%) older vs 9 (2.6%) younger patients; p < 0.01]. In the multivariate logistic regression analysis, age, white blood cell count (WBC), left ventricular ejection fraction (LVEF), RV-EDD basal and tricuspid annular plane systolic excursion (TAPSE) of less than 16 mm were found to be independently associated with in-hospital mortality. CONCLUSION: Older patients might experience greater rates of RV dilatation, RV dysfunction and atrial fibrillation during APE. In addition to age; elevated WBC, low LVEF, increased RV-EDD basal and TAPSE of less than 16 mm were independent predictors of mortality among study population.

RESUMEN

OBJECTIVES: Contrast-induced acute kidney injury (CI-AKI) is a life-threatening complication that leads to comorbidities and prolonged hospital stay lengths in the setting of peripheral interventions. The presence of some CI-AKI risk factors has already been investigated. In this study, we evaluated the predictors of CI-AKI after carotid artery stenting. METHODS: A total of 389 patients with 50% to 99% carotid artery stenosis who underwent carotid artery stenting were included in this study. Patients were grouped according to CI-AKI status. RESULTS: CI-AKI developed in 26 (6.6%) patients. Age, baseline creatinine level, neutrophil-to-lymphocyte ratio and platelet-to-lymphocyte ratio were higher and estimated glomerular filtration rate, haemoglobin and lymphocyte count were lower in CI-AKI patients. In the multivariate regression analysis, the neutrophil-to-lymphocyte ratio triggered a 1.39- to 2.63-fold increase in the risk of CI-AKI onset (p < 0.001). CONCLUSIONS: The neutrophil-to-lymphocyte ratio may be a significant predictor of CI-AKI in patients with carotid artery stenting and higher neutrophil-to-lymphocyte ratio values may be independently associated with CI-AKI.

RESUMEN

BACKGROUND: i ne prognostic relevance of hematological parameters in cardiovascular diseases has been well demonstrated. The purpose of the present study is to investigate the association between the hematological parameters, particularly neutrophil to lymphocyte ratio (NLR), and outcomes of aortic dissection (AD). METHODS: Two hundred patients diagnosed with AD were retrospectively recruited and compared with 76 subjects with ascending aortic dilatation (AAD) and 92 subjects with normal aortic diameters. The independent relation between hematological parameters and in-hospital mortality was analyzed by regression analysis. RESULTS: The NLR was significantly higher in the AD group compared to the AAD and control groups (median 8.83 [8.13] vs. median 1.95 [1.10] vs. median 1.71 [0.77], respectively; p = 0.01). The NLR was higher in the deceased (n = 57) compared to the surviving patients (n = 143) (median 10.37 [10.86] vs. median 7.84 [8.17]; p = 0.01). Receiver operating curve (ROC) analysis revealed that a NLR measurement higher than > 8.78 predicted in-hospital mortality for patients with acute aortic dissection with a sensitivity of 67.4% and a specificity of 57.2% (AUC: 0.672; p = 0.01). In multivariate logistic regression analysis, increased aortic diameter, acute dissection, and increased levels of NLR remained as the independent markers of in-hospital mortality within the study population. CONCLUSIONS: In patients with AD, NLR levels were increased compared to patients with AAD and controls and were independently associated with in-hospital mortality. This finding implicates that admission hematological parameters may have clinical importance in evaluating the mortality risk in patients with AD.

RESUMEN

BACKGROUND: The biochemical analysis of pericardial fluid for differentiating transudate from exudate is often ordered and interpreted according to the criteria extrapolated from pleural effusions. However, the validity of this discrimination when applied to pericardial effusion is under question. METHODS: Patients who underwent pericardiocentesis between January 2004 and February 2014 were identified. Among them, 216 had essential medical records available and constituted the study population. The parameters specifically analyzed were the following: lactate dehydrogenase, total protein and glucose concentrations in both pericardial fluid and serum; pericardial fluid/serum ratios of lactate dehydrogenase and total protein content; and pH and specific gravity of pericardial fluid. RESULTS: Eighty-one percent of pericardial effusions were classified as exudate according to Light's criteria. Both exudate and transudate fluid characteristics were possible for all etiological causes except for tuberculosis in which all were exudates. Although multiple cutoff points for all parameters were tested, significant overlap between different causes persisted (all having an area under the receiver operating characteristic curve of < 0.7). Thus, a reasonable accuracy to differentiate one cause from another could not be achieved. CONCLUSIONS: Although often ordered, the biochemical analysis of pericardial fluid has almost no diagnostic value to distinguish among causes of pericardial effusion in contemporary medicine.

RESUMEN

BACKGROUND: Efficacy of intravenous (IV) volume expansion in preventing contrast-induced acute kidney injury (CI-AKI) is well known. However, the role of oral hydration has not been well established. The aim of this work was to evaluate the efficacy of oral hydration in preventing CI-AKI. METHODS: We prospectively randomized 225 patients undergoing coronary angiography and/or percutaneous coronary intervention in either oral hydration or IV hydration groups. Patients who have at least one of the high-risk factors for developing CI-AKI (advanced age, type 2 diabetes mellitus, anemia, hyperuricemia, a history of cardiac failure or systolic dysfunction) were included in the study. All patients had normal renal function or stage 1-2 chronic kidney disease. Patients in the oral hydration group were encouraged to drink unrestricted amounts of fluids freely whereas isotonic saline infusion was performed by the standard protocol in the IV hydration group. RESULTS: CI-AKI occurred in 8/116 patients (6.9%) in the oral hydration group and 8/109 patients (7.3%) in the IV hydration group (p = 0.89). There was also no statistically significant difference between the two groups when different CI-AKI definitions were taken into account. CONCLUSION: Oral hydration is as effective as IV hydration in preventing CI-AKI in patients with normal kidney function or stage 1-2 chronic kidney disease, and who also have at least one of the other high-risk factors for developing CI-AKI.

RESUMEN

OBJECTIVE: This study aims to assess the predictive value of the Systemic Immune Inflammation Index (SII) in determining in-stent restenosis (ISR) likelihood in patients with acute coronary syndrome (ACS) who have undergone percutaneous coronary intervention (PCI). METHODS: The study enrolled 903 ACS patients undergoing PCI, categorized into ISR (+) and ISR (-) groups based on control coronary angiography results. Demographic, clinical, laboratory, and angiographic-procedural characteristics were systematically compared. RESULTS: The ISR (+) group encompassed 264 individuals (29.2%), while the ISR (-) group comprised 639 individuals (70.8%). Patients had a mean age of 55.8 ±â€…10.2 years, with 69% being male. The ISR (+) group had higher diabetes and smoking prevalence and notably larger stent dimensions. Lab parameters showed significantly elevated creatinine, total cholesterol, red cell distribution width, white blood cell and neutrophil counts, SII index and C-reactive protein (CRP) in the ISR (+) group, while lymphocyte levels were lower. Binary logistic regression identified stent diameter (odds ratio [OR]: 0.598, 95% confidence interval [CI]: 0.383-0.935; P  = 0.024), stent length (OR: 1.166, 95% CI: 1.132-1.200; P  < 0.001), creatinine (OR: 0.366, 95% CI: 0.166-0.771; P  = 0.003), CRP (OR: 1.075, 95% CI: 1.042-1.110; P  = 0.031), and SII index (OR: 1.014, 95% CI: 1.001-1.023; P  < 0.001) as independent ISR predictors. CONCLUSION: The SII index exhibits potential as a predictive marker for ISR in ACS patients post-PCI, indicating systemic inflammation and heightened restenosis risk. Integrating the SII index into risk models could identify high-risk patients for targeted interventions.

RESUMEN

The patients with ST-elevation myocardial infarction are primarily managed with percutaneous coronary intervention (PCI) or thrombolysis. It is well accepted that rescue PCI should be implemented in case of unsuccessful thrombolysis. However, the reverse, rescue thrombolysis, that is, administering of thrombolytic therapy in a patient in whom primary PCI fails, is not well defined. There are no available data about rescue thrombolysis so far. We represent a 43-year-old male patient with Buerger disease (thromboangiitis obliterans) who was admitted to our emergency department for cardiac shock related to inferior and right ventricular ST-elevation myocardial infarction. He was found to have occlusion of both right coronary artery and left anterior descending artery and managed with rescue thrombolysis. It was subsequently recognized that he had concurrent stroke caused by posterior cerebral artery (PCA) occlusion and improved with thrombolysis. It is reported for the first time that rescue thrombolysis has been put into practice and yielded great result after unsuccessful primary PCI.

RESUMEN

Patients with severe aortic regurgitation frequently present with angina pectoris. The exact pathophysiology for angina in aortic regurgitation is not clear. Left ventricular hypertrophy and myocardial blood supply-demand mismatch have been the suggested mechanisms to explain ischemia. However, no conclusive clinical study exists to define the incidence of ischemia in patients with severe aortic regurgitation and normal coronary arteries. We, therefore, investigated the frequency of myocardial ischemia in relation to left ventricular hypertrophy or dilatation in patients with severe aortic regurgitation and normal coronary arteries. We reviewed the medical records of all patients (n = 311) with aortic valve replacement due to aortic regurgitation between 2007 and 2010. We selected subjects with normal coronary arteries (n =182) for the study purpose, and we identified 35 patients who underwent myocardial perfusion scintigraphy prior to the coronary angiography (19 female and 16 male subjects; age 45.0 ± 8.9 years). Left ventricular hypertrophy and dilatation were detected in 9 (26%) and 5 (14%) patients, respectively. Myocardial perfusion scintigraphy showed evidence of ischemia in 10 (29%) patients with normal coronary arteries. The presence of ischemia did not relate to the presence of left ventricular hypertrophy and/or dilatation. As a potential mechanism, aortic regurgitation causes backflow of blood from the aorta into the left ventricle, hence disturbs coronary flow dynamics. In conclusion, myocardial ischemia is common (nearly one-third) among patients with severe aortic regurgitation even in the absence of coronary obstruction, left ventricular hypertrophy and/or dilatation.

RESUMEN

INTRODUCTION: In patients who have undergone interventional cardiac procedures, the risk of bleeding is higher than in patients who received conservative treatment due to multiple medications and comorbidities. AIM: This study aimed to evaluate the usefulness of the age, creatinine and ejection fraction (ACEF) score for predicting bleeding events and to compare short- and long-term clinical outcomes according to the ACEF score in patients with ST-elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention (pPCI) with bail-out tirofiban therapy (BOTT). MATERIAL AND METHODS: A total of 2,543 patients were included and divided into three groups according to the following ACEF score tertiles: T1 (ACEFlow ≤ 1.033), T2 (1.033 < ACEFmid ≤ 1.371), and T3 (ACEFhigh > 1.371). The main outcomes measured were the incidence rates of relevant bleeding events and mortality within 30 days and 3 years after the procedure. RESULTS: A total of 73 (2.9%) patients had Bleeding Academic Research Consortium bleeding events of grades 3, 4 or 5 and 104 (4%) patients died in a 30-day period. The ACEF score was effective at predicting 30-day bleeding (area under the receiver operating characteristic curve (AUC): 0.658, 95% confidence interval (CI): 0.579-0.737; p < 0.001), 30-day mortality (AUC = 0.701, 95% CI: 0.649-0.753; p < 0.001) and 3-year mortality (AUC = 0.778, 95% CI: 0.748-0.807; p < 0.001) events. Considering the ACEF score tertiles, T3 patients presented greater 30-day bleeding (1.6%, 2.8% and 4.1%; odds ratio (OR) = 2.56, 95% CI: 1.37-4.80), 30-day mortality (1.7%, 3.5% and 7.1%; OR = 4.53, 95% CI: 2.51-8.18) and 3-year mortality (6.4%, 11% and 19.8%; hazard ratio = 3.56, 95% CI: 2.58-4.91) risks. CONCLUSIONS: The ACEF score is a user-friendly tool with excellent predictive value for bleeding events and mortality in patients undergoing pPCI with BOTT.

RESUMEN

This study evaluated the impact of the baseline estimated glomerular filtration rate (eGFR) on clinical and angiographic outcomes and long-term in-stent restenosis (ISR) rates in patients undergoing elective carotid artery stenting (CAS) procedures. Consecutive patients who underwent CAS were retrospectively enrolled (n = 456). At the end of 3 years of follow-up, patients who had died or were lost follow-up were excluded from the study and a final analysis was performed using data from the remaining 405 patients. The study population (n = 405) was divided into 3 tertiles based on the tertile values of the eGFR level (T1, T2, and T3); then, clinical and procedural characteristics and 3-year ISR rates were compared between the groups. An ISR of 50% was detected in 49 (12%) surviving patients. The 3-year ISR was higher among patients with the lowest eGFR values (T1) by 3.7 times (95% CI: 2.01-11.38) than that among patients with the highest eGFR values (T3). These significant relationships persisted following adjustment for confounders. A lower baseline eGFR level was significantly associated with an increased ISR rate. Decreased renal function may be a predictor of ISR after CAS using first-generation stents.

RESUMEN

BACKGROUND: Despite the important role of some haematological parameters in tendency to thrombosis is known, their relationship with long-term stent thrombosis (ST) remains unclear. AIMS: This study aimed to investigate the association between the mean platelet volume (MPV) to platelet count (PC) ratio and long-term ST and mortality in patients with ST-segment-elevation myocardial infarction (STEMI) treated successfully by primary percutaneous coronary intervention (pPCI). METHODS: In a retrospective cohort study, according to their baseline MPV/PC ratios, 3667 consecutive STEMI patients undergoing pPCI were divided into three groups: tertile 1 (T1) (n = 1222, 0.357 ≥ MPV/PC ≥ 0.043), tertile 2 (T2) (n = 1222, 0.033 < MPV/PC < 0.043) and tertile 3 (T3) (n = 1223, 0.009 ≤ MPV/PC ≤ 0.032). Patients were followed up with for 5 years, focusing on ST and all-cause mortality outcomes. RESULTS: Patients with T1 displayed a greater 5-year ST rate, including a 2.76-fold greater (95% confidence interval 1.68-10.33) rate than that of patients with T3, who had the lowest rates and were used as the reference group. Meanwhile, the 5-year mortality rate was similarly higher among patients with T1 by 1.72 times (95% confidence interval 1.33-2.22) relative to that among patients with T3. These significant relationships persisted even after adjustment for all confounders. CONCLUSION: We found that higher MPV/PC ratios were associated with long-term ST and mortality. The MPV/PC ratio may constitute both a rapid and an easily obtainable parameter for identifying reliably high-risk patients who have undergone pPCI.

RESUMEN

In this study, we investigated the contribution of vitamin K epoxide reductase (VKORC1) and cytochrome P450 2C9 (CYP2C9) genotypes, age, and body surface area (BSA) on warfarin dose requirements and in an adult Turkish population. Blood samples were collected from 100 Turkish patients with stable warfarin dose requirements and an international normalized ratio (INR) of the prothrombin time within the therapeutic range. Genetic analyses for CYP2C9 genotypes (*2 and *3 alleles) and VKORC1 -1639 G>A polymorphism were performed and venous INR determined. The mean warfarin daily dose requirement was higher in CYP2C9 homozygous wild-type patients, compared to those with the variant *3 allele (P < 0.05), similar to those with the variant *2 allele (P > 0.05) and highest in patients with the VKORC1 -1639 GG genotype compared to those with the GA genotype and the AA genotype (P < 0.01). The time to therapeutic INR was longer in CYP2C9 homozygous wild-type patients compared with those with the variant *2 and *3 alleles (P < 0.01), and longer in patients with the VKORC1 (position -1639) GG genotype compared with those with the GA genotype and the AA genotype (P < 0.01). The multivariate regression model including the variables of age (R (2) = 4.4%), BSA (R (2) = 27.4%), CYP2C9 (R (2) = 8.1%), and VKORC1 genotype (R (2) = 34.1%) produced the best model for estimating warfarin dose (R (2) = 60.4%). VKORC1 genotype and CYP2C9 polymorphism affect daily dose requirements and time to therapeutic INR in Turkish patients receiving warfarin for anticoagulation.

RESUMEN

Myocardial noncompaction of the ventricular myocardium is a rare congenital cardiomyopathy characterized by excessively protrusive trabeculae and deep trabecular recesses in one or more segments of the ventricle. A 37-year-old male patient with prominent kyphoscoliosis presented with dyspnea. Transthoracic echocardiography showed trabeculations and deep intratrabecular recesses along the ventricular cavity in the apical and lateral segments of the left ventricle. Color Doppler imaging showed blood flow in these recesses. Diameters of the left ventricle and atrium were increased, with global hypokinesis of the left ventricle (ejection fraction 30%). Severe aortic valve stenosis was noted. Pulmonary function test showed moderate restriction. Due to high perioperative mortality, the patient was scheduled to medical treatment.

RESUMEN

BACKGROUND: It is difficult to determine left ventricular systolic performance in patients with severe mitral regurgitation (MR) since left ventricular ejection fraction (EF) could be preserved until the end stages of the disease. Myocardial efficiency (MEf) describes the amount of external work (EW) done by the left ventricle per unit of oxygen consumed (mVO2). In the present study, we aimed to investigate MEf in patients with asymptomatic severe MR using a novel echocardiographic method. METHODS: A total of 27 patients with severe asymptomatic MR and 26 healthy volunteers were included in this cross-sectional study. EW was measured using stroke volume and blood pressure, while mVO2 was estimated using double product and left ventricular mass. RESULTS: There were no differences between the groups with regards to EF (66% ± 5% vs. 69% ± 7%), while MEf was significantly reduced in patients with severe MR (25% ± 11% vs. 44% ± 12%, p < 0.001). This difference was maintained even after adjustment for age, gender and body surface area (adjusted x̅: 0.44, 95% CI: 0.39-0.49 for controls and adjusted x̅: 0.24, 95% CI: 0.19-0.29 for patients with severe MR). Further analysis showed that this reduction was due to an increase in total mVO2 in the severe MR group. MEf of thepatients who were both on ß-blockers and angiotensin converting enzyme inhibitors/angiotensin receptor blockers were higher than those who were not on any drugs, but this difference was not statistically significant (32% ± 15% vs. 23% ± 9%, p = 0.41). CONCLUSIONS: MEf was significantly lower in patients with asymptomatic severe MR and preserved EF.

RESUMEN

BACKGROUND AND AIM: The purpose of this study was to evaluate both the predictive value of metabolic syndrome (MS) on no-reflow phenomenon and 30-day clinical outcomes on patients undergoing primary percutaneous coronary intervention (PCI) for acute ST-elevation myocardial infarction (STEMI). METHODS AND RESULTS: One hundred and twelve consecutive patients (mean age 57+/-11 years, 94 male) with acute STEMI treated with primary PCI were analysed prospectively. Sum of ST-segment elevation was obtained immediately before and 60 min after the restoration of TIMI-3 flow. The difference between two measurements was accepted as the amount of ST-segment resolution and was expressed as summation operatorSTR. summation operatorSTR<50% was accepted as ECG sign of no-reflow phenomenon. Metabolic syndrome was defined based on Adult Treatment Panel-III criteria. The no-reflow was found in 22.3% of the entire group and was significantly higher in patients with MS than those without MS (43.7% vs. 13.7%, p<0.001). There was no significant difference in no-reflow between patients who had both MS and diabetes mellitus (DM) and patients who had MS but not DM (42.5% vs. 50%, respectively; p>0.05). CONCLUSION: The presence of MS may play an important role in the occurrence of no- reflow in STEMI treated with primary PCI.

RESUMEN

Left main coronary artery originating from the right coronary artery (RCA) is a rare anomaly. A 52-year-old male patient was submitted to catheterization laboratory for primary percutaneous coronary angioplasty with a diagnosis of acute anterior myocardial infarction. He had several risk factors including smoking, hypertension, and type 2 diabetes mellitus. Selective right coronary angiography showed an eccentric 85% stenosis at the mid-segment of the RCA, and the left main coronary artery originating from the right aortic sinus. The proximal segment of the left main coronary artery was completely occluded with thrombus and there was severe stenosis (95%) at the bifurcation of the left anterior descending artery with the circumflex artery. A metal stent was implanted in the stenotic segment of the left main coronary artery. The patient was discharged on the seventh day of stent implantation without any complications. Coronary artery bypass grafting was planned for stenotic lesions in the RCA and at the bifurcation of the left anterior descending artery with the circumflex artery.

RESUMEN

BACKGROUND: CHA2DS2-VASc score has been validated in risk prediction for stroke and thromboembolism in patients with atrial fibrillation (AF). Association of CHA2DS2-VASc score with higher risk of venous thromboembolism and pulmonary embolism (PE) has also been shown. In this study, we investigated the long-term prognostic value of CHA2DS2-VASc score in patients with acute pulmonary embolism (APE). METHODS: Consecutive patients with APE presenting to our emergency department were retrospectively recruited. Patients with AF and who died secondary to causes other than PE were excluded from the study. The CHA2DS2-VASc score and pulmonary embolism severity index (PESI) were calculated. RESULTS: Two hundred seventy seven participants were included in the study. The mortality rate was 18.7%. Twenty-two cases died within 30 days, and 30 cases died during the follow-up period (median: 13 months). The mean CHA2DS2-VASc score was significantly higher in dead patients compared to survivors (3.61 ± 1.35 vs 1.95 ± 1.52, P < .01). In multivariate regression analysis, systolic pulmonary artery pressure (hazard ratio [HR]: 1.03, 95% confidence interval [CI]: 1.01-1.06, P = .02), PESI score (HR: 1.010, 95% CI: 1.004-1.017, P < .01), and CHA2DS2-VASc score (HR: 1.67, 95% CI: 1.19-2.16, P < .01) were found to be independently correlated with mortality. The patients whose CHA2DS2-VASc score was between 1 and 3 had 5.67 times and patients whose CHA2DS2-VASc score was ≥4 had 16.8 times higher risk of mortality compared to patients with CHA2DS2-VASc score = 0. CONCLUSION: Patients with higher CHA2DS2-VASc scores had higher rates of mortality after APE.

RESUMEN

BACKGROUND: The presence of Q waves at presentation with a first acute ST-segment elevation myocardial infarction (STEMI) reflects a more advanced stage of the infarction. Resolution of ST-segment elevation indicating successful myocyte reperfusion may differ according to how far the infarction process has progressed. The Selvester QRS score measures infarct size. The purpose of this study was to evaluate the predictive value of QRS score on ST-segment resolution and 30-day clinical outcomes in patients with acute STEMI undergoing primary percutaneous coronary intervention (PCI). METHODS: We conducted a prospective cohort study in 112 consecutive patients (mean age 57 +/- 11 years, 94 men, 18 women) with first acute STEMI of <12-hour onset who underwent successful (TIMI-3 flow) primary PCI. The Selvester QRS score was estimated on the first electrocardiogram (ECG) after hospital admission. Sum of ST-segment elevation amount in millimeters was obtained immediately before angioplasty and 60 minutes after the restoration of TIMI-3 flow. The difference between 2 measurements was accepted as the amount of ST-segment resolution and expressed as summation sigmaSTR. summation sigmaSTR <50% was accepted as ECG sign of no-reflow phenomenon. Follow-up to 30-day was performed. RESULTS: The no-reflow phenomenon was more often observed in patients with high QRS score (> or = 4) than in those with low QRS score (34.4% and 6.3%, P < .001). Thirty-day composite major adverse cardiac event (MACE) rate was 14% in patients with high QRS score versus 0% in low QRS score group (P = .007). After adjusting for baseline characteristics, high QRS score remained a strong independent predictor of no-reflow (OR 4.1, 95% CI 1.5-10.7, P = .005) and MACE (OR 1.8, 95% CI 1.1-2.9, P = .011). CONCLUSIONS: The presence of high QRS score is an independent predictor of incomplete ST recovery and 30-day MACE in STEMI treated with primary PCI.
