RESUMO
BACKGROUND: Guidelines for the diagnosis and management of atrial fibrillation (AF) are frequently published and updated, reflecting the rapid evolution in AF pathogenesis and treatment modalities. SUMMARY: Recently, 2 important guidelines for the diagnosis and management of atrial AF have been published by the European Society of Cardiology (ESC), and Canadian Cardiovascular Society (CCS). Although the evidence-based recommendations and statements are quite similar, there are some important differences between the ESC and CCS guidelines for AF. Herein, we compared the current recommendations and highlighted the differences from the most recent guidelines for AF. Key Messages: Specifically, key differences can be observed in methods evaluating the recommendations; classifications and the definitions; the symptom score used to guide management decisions, longitudinal patient assessment, and structured characterization; the stroke risk stratification algorithm used to determine indications for oral anticoagulation therapy; the role of acetylsalicylic acid in stroke prevention in AF; the antithrombotic regimens that are employed in the setting of chronic coronary syndromes, acute coronary syndromes, and percutaneous coronary intervention; the target heart rate for rate control; and the algorithms for integrated or holistic management of AF. Differences are observed, particularly when the quality of evidence is moderate or low. More research and randomized controlled studies on major gaps identified in current guidelines will further clarify and modify our future management strategies in AF.

OBJECTIVE: Fingertip-reactive hyperemia-peripheral artery tonometry (RH-PAT) is an emerging novel noninvasive method for evaluating endothelial function. We aimed to evaluate endothelial function with fingertip-reactive hyperemia by RH-PAT in symptomatic patients undergoing elective coronary angiography and to assess the relationship between the degree of endothelial dysfunction (ED) and the presence and the severity of coronary artery disease (CAD). SUBJECTS AND METHODS: We assessed 92 patients. Before coronary angiography, endothelial function was measured by RH-PAT and reactive hyperemia index (RHI) was obtained. For each patient, the Gensini score was calculated according to the coronary angiographic findings to evaluate the severity of CAD. RESULTS: In CAD (+) group, RHI (1.35 ± 0.57 vs. 1.74 ± 0.46, p = 0.001) mean values were lower than CAD (-) group. In multivariate logistic regression analysis, age, high-density lipoprotein, and RHI were found to be independent parameters predicting the presence of CAD. In multivariate linear regression analysis, RHI was found to be an independent predictor associated with the severity of CAD. In receiver operating characteristic curve analysis, RHI achieved an area under the curve of 0.763 (95% confidence interval 0.663-0.846, p = 0.001) for the ability to predict the presence of CAD. A cut-off value of 1.49 for an RHI predicted the presence of CAD with a sensitivity of 75% and a specificity of 72.9%. CONCLUSION: RH-PAT is an objective and highly reproducible test with superior diagnostic accuracy for the evaluation of ED. We found significant correlations between ED and the presence and the severity of CAD.

Aim Increasing evidence suggests that autonomic dysfunction may be involved in the etiology of white coat hypertension (WCH). The aim of this study was to evaluate cardiac autonomic function by using heart rate recovery (HRR) indices in patients with WCH classified according to their circadian rhythm type of blood pressure (BP).Material and methods This cross-sectional study included 120 participants over the age of 18 yrs, including 50 patients diagnosed with WCH and 70 healthy controls with normal in- and out-of-office BP and without any known disease. Circadian rhythm types, i.e., dippers and non-dippers, were identified using ambulatory BP monitoring. The HRR indices were calculated by subtracting the 1st-minute (HRR1), 2nd-minute (HRR2), and 3rd-minute (HRR3) heart rates from the maximal heart rate recorded during stress testing.Results The lesser decline in nighttime BP (6.4±2.14 and 13.3±2.2 mmHg, respectively; p<0.001) and the smaller mean HRR1 (25.5±3.0 and 30.3±3.1 beatsâ/âmin, respectively; p<0.001) were evident in WCH non-dippers compared to WCH dippers. Linear regression analysis showed that HRR1 (ß±SE=0.43±0.11; p<0.001) and diastolic BP at maximum exercise (ß±SE=0.14±0.07; p=0.040) are independent risk factors for the blunted decline in nighttime BP.Conclusion Delayed recovery of heart rate after an exercise stress test is associated with non-dipper type of circadian rhythm of BP. This was more pronounced in WCH patients, and these patients are at risk of autonomic dysfunction.

Echocardiography is the most helpful diagnostic modality in cardiogenic shock, the management of which still remains challenging despite advances in therapeutic options. The presence of cardiogenic shock portends high mortality rates. Therefore, rapid recognition, identification of the underlying cause, and evaluation of the severity of hemodynamic dysfunction are vital for correct management. Whether the cause of shock is unknown, suspected, or established, echocardiography is utilized in its diagnosis and management as well as to monitor progress. It is recommended as the modality of first choice. No other investigative bedside tool can offer comparable diagnostic capability, allowing for exact targeting of the underlying cardiac and hemodynamic problems. Echocardiography can promptly provide an impression of the etiology of shock and the potential line of treatment. Normal left ventricular and right ventricular systolic function, normal cardiac chamber dimensions, absence of any significant valvular pathology, and absence of any pericardial effusion virtually rule out a cardiac cause of shock. This review discusses the role of echocardiography as a decision-making tool in the evaluation and management of cardiogenic shock.

BACKGROUND: Angiotensin receptor neprilysin inhibitors (ARNI; sacubitril/valsartan combination) decrease morbidity and mortality in heart failure with reduced ejection fraction (HFrEF). Increased Pwave duration and Pwave dispersion (Pd) reflect prolongation of atrial conduction and correlate with atrial fibrillation. Here, we aimed to assess the effects of switching from valsartan to ARNI treatment on the basis of Pwave indices. METHODS: A total of 28 patients with HFrEF (mean age, 64.8⯱ 10.6 years; 18 males, 78.6% ischemic etiology) were included. All patients had New York Heart Association functional class II-III, left ventricular ejection fraction ≤35%, and had been switched from valsartan to ARNI treatment. Standard 12-lead electrocardiograms from patients on valsartan treatment and electrocardiograms 1 month after ARNI treatment were analyzed; heart rate, maximum Pwave duration (Pmax), minimum Pwave duration (Pmin), and Pd were calculated. Minnesota Living with Heart Failure Questionnaire (MLWHFQ) scores and Nterminal pro-brain natriuretic peptide (NT-proBNP) values were recorded. RESULTS: The Pmax (135.6⯱ 32.1â¯ms vs. 116.1⯱ 14.1â¯ms, pâ¯= 0.041) and Pd (33.6⯱ 7.9 vs. 28.6⯱ 5.3, pâ¯= 0.006) values were significantly reduced after ARNI treatment. Furthermore, ARNI treatment was associated with an improvement in MLWHFQ scores (31.2⯱ 6.2â¯ms vs. 23.2⯱ 7.0â¯ms, pâ¯< 0.001) and with a reduction in NT-proBNP values (1827.3⯱ 1287.3â¯pg/ml vs. 1074.4⯱ 692.3â¯pg/ml, pâ¯< 0.001). There were moderately positive correlations between the reduction in Pd and the improvement in MLWHFQ scores (râ¯= 0.408, pâ¯= 0.031) and the reduction in NT-proBNP values (râ¯= 0.499, pâ¯= 0.007) CONCLUSION: Switching to ARNI treatment alters Pd and Pmax favorably in patients with HFrEF. The reduction in atrial inhomogeneous conduction assessed by Pd was correlated with clinical improvement and reduced NT-proBNP levels in patients with HFrEF.

PURPOSE OF REVIEW: Percutaneous coronary intervention (PCI) is a commonly used treatment option in coronary artery disease (CAD). Reduced major adverse cardiovascular events (MACE) in those randomized to PCI compared to optimal medical therapy have been demonstrated only if it is performed for physiologically significant coronary lesions. Despite data demonstrating improved outcomes primarily in stable CAD and then acute settings, physiology-guided PCI remains underutilized. This review summarizes the evidence and commonly used methods for physiologic assessment of coronary stenosis. RECENT FINDINGS: Fractional flow reserve (FFR) is the gold standard for the analysis of lesion severity. Its use is limited by the need for adenosine, which adds time, complexity, and potential adverse effects. Non-hyperemic instantaneous wave-free ratio-guided revascularization and quantitative flow reserve ratio assessment both have shown safety and effectiveness with improved patient outcomes. Coronary physiological assessment solves the ambiguity of coronary angiography. Detecting physiologically significant stenoses is crucial to decide which lesion needs to be treated. Technological advances have led to the development of new assessment indices in addition to FFR.

BACKGROUND: Lead exposure causes a wide range of vascular diseases through oxidative stress, sympathetic hyperactivity and impairment in nitric oxide bioavailability. In this study, the association between the effects of lead exposure on left ventricular diastolic indices and erectile function were assessed. METHODS: A total of 94 lead-exposed workers without known cardiovascular diseases or risk factors and 30 healthy subjects were enrolled. Systolic and diastolic functions were measured using transthoracic echocardiography. All participants were non-smokers. The International Index of Erectile Function Questionnaire (IIEF-5) was used to diagnose and grade erectile dysfunction (ED). Echocardiographic parameters, IIEF-5 score and blood lead level (BLL) were analyzed. RESULTS: The mean age and median BLL were 32.3 ± 6.4 years and 19 µg/dL in the workers, respectively. Sixty-five (69.1%) workers and 9 control subjects (30%) had ED. The IIEF-5 score was lower in the workers (17.0 ± 6.1) than in the controls (22.7 ± 2.1). In the workers, E and e' waves and E/A ratio were lower, and A wave, E/e' ratio, and left atrial volume index (LAVI) were higher than in the controls. Additionally, BLL was correlated with IIEF-5 score, e' wave, and E/e' ratio. IIEF-5 score was correlated with e' wave, E/e' ratio and LAVI. BLL was an independent risk factor for a decreased e' wave and IIEF-5 score and increased E/e' ratio in the lead-exposed workers. CONCLUSIONS: Impairment of diastolic and erectile functions, despite a younger age and in the absence of accompanying risk factors, was correlated with increased BLL.
RESUMO
BACKGROUND: Copeptin is widely used as a predictor of an adverse prognosis in many clinical conditions. Reduced antegrade coronary flow in an infarct-related artery (IRA) is associated with adverse clinical outcomes in patients with ST-segment elevation myocardial infarction (STEMI). The aim of this study was to investigate whether copeptin level on admission was associated with IRA patency in STEMI patients. METHODS: A total of 88 patients were enrolled into the study and divided into two groups according to TIMI flow grade in the IRA before primary percutaneous coronary intervention. RESULTS: White blood cell count (p = 0.015), neutrophils (p = 0.047), N-terminal pro-brain natriuretic peptide (NTproBNP) (p < 0.001), copeptin (p < 0.001) and peak troponin I (p = 0.001) were significantly higher in the occluded IRA group with a significantly lower serum sodium level (p < 0.001). Age- and gender-adjusted multivariate analysis revealed that copeptin (OR = 1.970; p = 0.001), peak troponin I (1.055; p = 0.005) and NTproBNP (OR = 1.003; p = 0.010) were independent predictors of an occluded IRA. A copeptin cut-off value of > 6.8 ng/mL was found to predict an occluded IRA with a sensitivity of 80% and specificity of 100% (area under the curve: 0.917; p < 0.001). Performance ranking of the biomarkers that could predict an occluded IRA showed copeptin > peak troponin I = NTproBNP. CONCLUSIONS: Copeptin levels were higher in the patients with an occluded IRA and STEMI. Higher levels of copeptin predicted an occluded IRA in the patients with STEMI who were admitted to the emergency department during the first three hours of chest pain.
RESUMO
PURPOSE: The objectives of this study were to: (i) evaluate endothelial function via fingertip reactive hyperemia peripheral arterial tonometry (RH-PAT) among heart failure (HF) patients receiving cardiac resynchronization therapy (CRT), (ii) assess the effects of CRT on RH-PAT score, and (iii) investigate whether RH-PAT score can identify CRT response. METHODS: A total of 63 patients (61.8 ± 10.3 years; 50 males; left ventricular (LV) ejection fraction 24.3 ± 3.9%) with HF who received CRT were enrolled. Endothelial function via RH-PAT was assessed 1 day before and 6 months after CRT. Minnesota Living with Heart Failure Questionnaire (MLWHFQ) was used to assess clinical improvements. CRT response was defined as a reduction in LV end-systolic volume ≥ 15% at 6 months. RESULTS: A RH-PAT score of < 1.7 signified a cut-off for endothelial dysfunction (ED). Baseline ED was observed among 43 (68.3%) patients and was more prevalent in responders (76.1% vs. 47.1%, p = 0.037). RH-PAT score improved 6 months after CRT (1.58 ± 0.35 vs. 1.71 ± 0.31, p = 0.012). A RH-PAT score of < 1.7 was a significant independent predictor of CRT response in multivariate logistic regression analysis (ß = 1.275, OR = 3.512, 95% CI = 1.231-11.477, p = 0.032). The severity of ED was an independent predictor of LV reverse remodeling (ß = -8.873, p = 0.015). Spearman's correlation analysis revealed moderate positive correlations between an improvement in RH-PAT (ΔRH-PAT) and LV reverse remodeling (r = 0.461, p = 0.001) and MLWHFQ score (r = 0.440, p = 0.001). CONCLUSIONS: ED detected via RH-PAT could predict the response to CRT. The RH-PAT score increased 6 months after CRT and was correlated with echocardiographic and clinical improvements.
RESUMO
AIMS: The aims of this study include (i) pursuing data-mining experiments on the Angiotensin II-Antagonist in Paroxysmal Atrial Fibrillation (ANTIPAF-AFNET 2) trial dataset containing atrial fibrillation (AF) burden scores of patients with many clinical parameters and (ii) revealing possible correlations between the estimated risk factors of AF and other clinical findings or measurements provided in the dataset. METHODS: Ranking Instances by Maximizing the Area under a Receiver Operating Characteristics (ROC) Curve (RIMARC) is used to determine the predictive weights (Pw) of baseline variables on the primary endpoint. Chi-square automatic interaction detector algorithm is performed for comparing the results of RIMARC. The primary endpoint of the ANTIPAF-AFNET 2 trial was the percentage of days with documented episodes of paroxysmal AF or with suspected persistent AF. RESULTS: By means of the RIMARC analysis algorithm, baseline SF-12 mental component score (Pw= 0.3597), age (Pw= 0.2865), blood urea nitrogen (BUN) (Pw= 0.2719), systolic blood pressure (Pw= 0.2240), and creatinine level (Pw= 0.1570) of the patients were found to be predictors of AF burden. Atrial fibrillation burden increases as baseline SF-12 mental component score gets lower; systolic blood pressure, BUN and creatinine levels become higher; and the patient gets older. The AF burden increased significantly at age >76. CONCLUSIONS: With the ANTIPAF-AFNET 2 dataset, the present data-mining analyses suggest that a baseline SF-12 mental component score, age, systolic blood pressure, BUN, and creatinine level of the patients are predictors of AF burden. Additional studies are necessary to understand the distinct kidney-specific pathophysiological pathways that contribute to AF burden.

AIMS: Data mining is the computational process to obtain information from a data set and transform it for further use. Herein, through data mining with supportive statistical analyses, we identified and consolidated variables of the Flecainide Short-Long (Flec-SL-AFNET 3) trial dataset that are associated with the primary outcome of the trial, recurrence of persistent atrial fibrillation (AF) or death. METHODS AND RESULTS: The 'Ranking Instances by Maximizing the Area under the ROC Curve' (RIMARC) algorithm was applied to build a classifier that can predict the primary outcome by using variables in the Flec-SL dataset. The primary outcome was time to persistent AF or death. The RIMARC algorithm calculated the predictive weights of each variable in the Flec-SL dataset for the primary outcome. Among the initial 21 parameters, 6 variables were identified by the RIMARC algorithm. In univariate Cox regression analysis of these variables, increased heart rate during AF and successful pharmacological conversion (PC) to sinus rhythm (SR) were found to be significant predictors. Multivariate Cox regression analysis revealed successful PC as the single relevant predictor of SR maintenance. The primary outcome risk was 3.14 times (95% CI:1.7-5.81) lower in those who had successful PC to SR than those who needed electrical cardioversion. CONCLUSIONS: Pharmacological conversion of persistent AF with flecainide without the need for electrical cardioversion is a powerful and independent predictor of maintenance of SR. A strategy of flecainide pretreatment for 48 h prior to planned electrical cardioversion may be a useful planning of a strategy of long-term rhythm control.

Nose bleeding is a common situation seen in otorhinolaryngological practices. One of the greatest risk factors in nose bleeding is the use of anticoagulant medicine. With the medicine developed in recent years, the risk of nose bleeding due to the frequent use of anticoagulant and antiagregant is gradually increasing.The purpose of this study is to determine the effects of especially new-generation anticoagulants on nose bleeding. In addition, the use and complications of new-generation anticoagulants and antiagregants have been compiled in light of information obtained from the literature.Three hundred forty patients whose follow-up is conducted by the cardiology department and who use oral antithrombocytic medicine have been included in the study. It has been determined that 15% of these patients use new-generation oral anticoagulants (Rivaroksaban, apiksaban, dabigatran, danaparoid) and the other patients are treated with conventional antithrombocytic treatment (Aspirin, Warfarin, Enoksaparin sodium). The rate of nose bleeding in patients who use classical anticoagulants has been observed to be 28%. In 30 of these patients who had nose bleeding, while cauterization and buffering by otorhinolaryngology specialists, major intervention has not been necessary for any of the patients. While bleeding has been observed in 26% of the patients who use new-generation anticoagulants, bleeding that required operational intervention has taken place in 2 patients. Bleedings have been stopped surgically through a large number of cauterization and buffering.While the new-generation anticoagulants cause lower rate of bleeding, it has been observed that controlling these bleedings is more difficult.

OBJECTIVE: To assess exercise heart rate recovery (HRR) indices in patients with systemic sclerosis (SSc) for an assessment of their cardiac autonomic function. SUBJECTS AND METHODS: Thirty-five patients with diffuse or limited SSc and 35 healthy controls were enrolled. All subjects underwent exercise testing and transthoracic echocardiography. The HRR indices were calculated by subtracting the first- (HRR1), second- (HRR2) and third-minute (HRR3) heart rates from the maximal heart rate. RESULTS: The SSc and control groups were similar in age (45.2 ± 11.6 vs. 43.9 ± 10.0 years), had identical gender ratios (31 female/4 male in both groups) and similar left ventricular ejection fraction (66.5 ± 5.1 vs. 67.7 ± 5.9%). The mean HRR1 (21.8 ± 4.4 vs. 27.7 ± 4.3 bpm, p = 0.001), HRR2 (43.8 ± 6.3 vs. 47.6 ± 4.4 bpm, p = 0.004) and HRR3 (58.8 ± 10.3 vs. 63.6 ± 7.3 bpm, p = 0.031) values were significantly lower in the SSc group than in the healthy controls. HRR indices were similar in the limited and diffuse SSc subgroups. CONCLUSIONS: The patients with SSc had lower HRR indices than normal subjects. Cardiac autonomic functions might be involved in SSc, even in patients without cardiac symptoms.

OBJECTIVES: Behçet's disease (BD) is a chronic, multisystemic disorder characterised by recurrent oral aphtous ulcers, genital ulcers and ocular inflammation. Vasculitis and thrombotic events are the most important causes of mortality. Vena cava thrombosis, pulmonary artery aneurysms, Budd-Chiari syndrome, peripheral artery aneurysms, dural sinus thrombosis and abdominal aorta aneurysms are the other less common vascular manifestations of BD. Cardiac involvement in BD is a rare and life-threatening complication. The aim of this study was to assess the clinical characteristics and outcome of patients with BD who have intracardiac thrombus. METHODS: The hospital files of BD patients followed by rheumatology clinics of four medical centres (Ankara University, Ege University, Hacettepe University and Eskisehir Osmangazi University Hospitals) were retrospectively evaluated. Data included patients' demographic and clinical features, laboratory findings and outcome. All patients fulfilled three or more of the International Study Group Criteria for BD. RESULTS: Twenty-two patients with intracardiac thrombus were evaluated. The mean age of patients with intracardiac thrombosis was 29.1 yrs (22-44) and there was a male predominance with a ratio of 20:2. Cardiac involvement was the first clinical manifestation of BD in 9 of the 22 patients. Initial symptoms of the patients were fever (n=18, 81%), dyspnea (n=9, 40%) chest pain (n=9, 40%) and haemoptysis (n=7, 31.8%). Sixteen patients (72%) had pulmonary arteritis and 10 (45%) patients had venous system lesions included deep vein, inferior vena cava and hepatic vein. Intra-cardiac thrombus were found only in the right cavities in 17 patients (77%), only in the left cavities in 2 patients (9%), and in both left and right cavities of the heart in 3 patients (13.6%). Once the cardiac lesion was diagnosed as a complication of BD, high dose (1mg/kg/d) prednisone (n=22, 100%) plus cyclophosphamide (n=18, 81%) or azathioprine (n=3, 13.6%) and warfarin (n=8, 36.3% (after the elimination of pulmonary aneurysm) therapy for anticoagulation was initiated. Four patients (18%) had high dose prednisone plus cyclophosphamide plus interferon-α (IFN-α) combination treatment and two patients (n=2, 9%) had high dose prednisone plus cyclophosphamide or plus azathioprine combination treatment. After treatment, the intra-cardiac thrombus disappeared in 13 cases and the size of the thrombus reduced in 7 cases. One patient died because of recurrent intra-cardiac thrombus and massive pulmonary arteritis in the emergency department. CONCLUSIONS: Intracardiac thrombus in BD is more common in young men. The right side of the heart is usually involved and cardiac involvement is often accompanied by pulmonary artery occlusion possibly due to pulmonary arteritis. Early and aggressive immunosuppressive and/or anticoagulation therapy are life-saving.
