RESUMO
BACKGROUND: The aim of this study was to provide insight into the real-life clinical presentation and outcomes of the elderly presenting with acute myocardial infarction from the Turkish Myocardial Infarction registry database. METHODS: TURKMI was a nationwide, multicenter, observational, 15-day snapshot registry conducted to address the management of acute myocardial infarction patients admitted to percutaneous intervention-capable hospitals. The present analysis included the comparison of consecutively enrolled acute myocardial infarction patients aged ≥75 and <75 years. RESULTS: Of the overall 1930 patients, 362 patients were aged ≥75 years. Elderly patients were more likely to have hypertension and renal failure and less likely to have hypercholesterolemia. Elderly patients were admitted to hospitals almost 1 hour later mainly due to a late call to emergency medical service. At discharge, medical therapies were significantly less prescribed to the elderly. The proportion of patients undergoing coronary angiography was significantly lower in elderly (81.8% vs. 96.4%, P < .001). Both in-hospital and 1-year mortality were significantly higher in elderly patients (9.1% vs. 2.7% and 22.7% vs. 5.8%, P < .001 respectively). The adjusted risk of 1-year mortality was 4-fold in elderly (hazard ratio and 95% CI 4.0 [2.9-5.6], P < .001). In multivariate analysis, every 5-beat/min increase in heart rate increased mortality by 7%. Higher heart rate and use of antiplatelet agents on admission were predictors of mortality in elderly. CONCLUSION: In real-life settings, elderly patients presenting with acute myocardial infarction are prone to prolonged total ischemic time and are subjected to less-intensive medical treatment and interventional approaches. Besides age, the increased heart rate could be the major determinant of mortality.

AIMS: The relationship between chronic kidney disease and development of heart failure is a well-known clinical entity. Systolic dyssynchrony index (SDI_16) is a new diagnostic tool for detection of subclinical left ventricular (LV) systolic dysfunction by using three-dimensional echocardiography (3DE). We aimed to investigate this parameter in patients with end-stage renal disease who were receiving hemodialysis and patients with renal transplant compared to healthy control subjects. MATERIAL AND METHODS: Forty-five hemodialysis patients, 45 patients with renal transplant and 45 age-sex matched healthy control subjects included in the study. All participants were evaluated with 3DE in the interdialytic phase for measurement of LV volumes, ejection fraction and SDI_16 parameter. RESULTS: Both LV diastolic and systolic volumes were significantly higher in hemodialysis group compared to renal transplant group and healthy controls, but this finding did not translate to a statistically significant difference for LVEF measurements between groups (58.71 ± 3.53 vs. 57.17 ± 2.97 vs. 59.23 ± 3.26, p = .16 for renal transplant and hemodialysis and healthy control groups, respectively). Mean value of SDI_16 parameters was significantly higher in hemodialysis group compared to renal transplant group (7.93 ± 2.50 vs. 3.72 ± 1.71, p < .001) and healthy controls (7.93 ± 2.50 vs. 3.00 ± .99, p < .001); whereas, it was similar between renal transplant group and control subjects (3.72 ± 1.71 vs. 3.00 ± .99, p = .10). CONCLUSION: SDI_16 was significantly higher in hemodialysis patients compared to patients with renal transplant and healthy controls.

OBJECTIVE: Although the prevalence and rate of myocardial infarction with non-obstructive coronary arteries (MINOCA) are higher in women than in men in previous cohorts, potential demographic and clinical differences between women who are diagnosed with MINOCA versus myocardial infarction with obstructive coronary arteries (MIOCA) have not been studied till date. In this study, we aimed to document these characteristics and to compare them between female patients with MINOCA and MIOCA. METHODS: The study was a subgroup analysis of the MINOCA-TR study. The study was a multi-center, observational cohort study that was conducted in Turkey between March 2018 and October 2018. In this study, 477 (29.3%) female patients who had been diagnosed with acute myocardial infarction were evaluated. RESULTS: Of these women, 49 (10.3%) were diagnosed with MINOCA (mean age 58.9±12.9 years) and 428 (89.7%) had a final diagnosis of MIOCA (mean age 67.4±11.8 years). The prevalence of hypertension, hyperlipidemia, and diabetes mellitus was significantly lower in the MINOCA group than in the MIOCA group. In addition, the MINOCA group had higher rates of recent flu history and non-ST elevation myocardial infarction (NSTEMI) presentation than the MIOCA group. There were significant clinical differences in patients with MINOCA in terms of sex. The female patients were older, had higher systolic blood pressures, and lower hemoglobin levels than male patients. CONCLUSION: The study revealed that the prevalence of traditional coronary artery disease risk factors was lower in female patients with MINOCA than in those who had final diagnosis of MIOCA.

OBJECTIVE: The D-SPIRIT registry is designed to investigate the safety and effectiveness of dabigatran etexilate in patients with atrial fibrillation in routine clinical practice. METHODS: D-SPIRIT is the first national, multicenter, prospective, observational, postmarketing registry that investigates the usage of dabigatran in real life. A total of 326 noveloral anticoagulant-eligible patients with atrial fibrillation who have been taking dabigatran etexilate therapy for stroke prevention at least 6 months from 9 different centers were enrolled into the registry. Patients were followed up for 2 years to evaluate the effectiveness and safety of the treatment. All adverse clinical events including bleeding, thromboembolic events, stroke, systemic embolism, transient ischemic attack, myocardial infarction, and all-cause death were recorded. RESULTS: The mean age was 71.1±9.6 years, and 57.4% of the study participants were female. The mean CHA2DS2-VASc (congestive heart failure, hypertension, age ≥75 years, diabetes mellitus, stroke or transient ischemic attack [TIA], vascular disease, age 65-74 years, sex category) score was 3.4±1.6. The cumulative adverse clinical events rate was 6.30% per year. The rate for embolic events including TIA, ischemic stroke, and peripheral embolism was 1.26% per year. The rate for major bleeding was 2.20% per year, and the mortality rate was 0.94% per year. CONCLUSION: This registry obtained an important overview of the current safety and effectiveness of the dabigatran etexilate in Turkey. Our results indicate similar rates of thromboembolic and bleeding events with pivotal phase 3 trial and other real-life registries. However, rate of undertreatment usage of dabigatran etexilate in real life was found to be considerable.

BACKGROUND: Atrial fibrillation (AF) prevalence in patients with acute myocardial infarction (MI) ranges from 3% to 25%. However demographic, clinical, and angiographic characteristics of AF patients who admitted with de novo MI are unclear. The aim of this study was to investigate the prevalence of patients presenting with de novo MI with AF. METHODS: The study was performed as a sub-study of the MINOCA-TR (Myocardial Infarction with Non-obstructive Coronary Arteries in Turkish Population) Registry, a multicenter, cross-sectional, observational, all-comer registry. MI patients without a known history of stable coronary artery disease and/or prior coronary revascularization were enrolled in the study. Patients were divided into AF and Non-AF groups according to presenting cardiac rhythm. RESULTS: A total of 1793 patients were screened and 1626 were included in the study. The mean age was 61.5 (12.5) years. 70.7% of patients were men. The prevalence of AF was 3.1% (51 patients). AF patients were older [73.4 (9.4) vs. 61.0 (12.4) years, p<0.001] than non-AF patients. The proportion of women to men in the AF group was also higher than in the non-AF group (43.1% vs. 28.7%, p=0.027). Only 1 out of every 5 AF patients (10 patients, 19.6%) was using oral anticoagulants (OAC). CONCLUSIONS: AF prevalence in patients presenting with de novo MI was lower than previous studies that issued on AF prevalence in MI cohorts. The majority of AF patients did not have any knowledge of their arrhythmia and were not undergoing OAC therapy at admission, emphasizing the vital role of successful diagnostic strategies, patient education, and implementations for guideline adaptation.
RESUMO
BACKGROUND: Cirrhotic cardiomyopathy (CCM) is a well-known entity. The aim of this study was to compare left atrial three-dimensional (3D) volume and P-wave dispersion (PWd) in patients with cirrhosis and a healthy population. The secondary purpose was to assess the left phasic volumes and reservoir functions with 3D echocardiography for the prediction of an increased risk of poor outcomes in patients with cirrhosis. METHODS: The study included 50 patients with cirrhosis and 43 healthy control subjects without atrial fibrillation. All patients were assessed with two-dimensional (2D), 3D, and tissue Doppler transthoracic echocardiography. The PWd was calculated using a 12-lead surface electrocardiogram (ECG). Cirrhotic patients were followed up for 2.5 years for the evaluation of poor outcomes and the development of atrial fibrillation. RESULTS: Patients with cirrhosis were observed to have significantly higher left atrial phasic volumes such as minimal left atrial volume (3D-LAVmin, P = 0.004) and indexed LAVmin (3D-LAVImin, P = 0.0001), and significantly decreased left atrial reservoir functions such as left atrial emptying volume (3D-LAEV, P = 0,001), left atrial ejection fraction (3D-LAEF, P = 0,001) on 3D echocardiography. PWd was determined to be significantly longer in the cirrhotic group compared with the control group (P = 0.003). In the 2.5-year follow-up period, poor outcomes occurred in 34 patients (22 patients died, six patients had liver transplantation, six patients developed atrial fibrillation/AHRE episodes). In Cox regression analysis, the MELD score (HR, 1.16 (1.06-1.26), P = 0.001) and 3D-LAVImin (HR, 0.95 (0.86-1.00), P = 0.040) were significantly associated with all-cause mortality. Cirrhotic patients with LAVImin of >15 ml/m2 were seen to have poor survival (long rank P = 0.033). CONCLUSION: The results of this study showed that patients with cirrhosis had higher left atrial volume, longer PWd and worse diastolic functions compared with the control group. Higher disease severity scores were associated with left atrial function and volume. In addition, left atrial volume measured with 3DE was a strong predictor of future adverse events, and minimal left atrial volumes had a higher prognostic value than any other left atrial function indices.

PURPOSE: The syndromes of myocardial infarction/myocardial ischemia with No Obstructive Coronary Artery Disease (MINOCA/INOCA) are seen more and more often. Endothelial dysfunction (ED) leading to ischemic events has been reported in many of these patients. We aimed to compare patients with MINOCA and INOCA regarding brachial artery flow-mediated endothelium-dependent vasodilation (flow-mediated dilation [FMD]) and plasma concentration of cardiotrophin-1 (CT-1). METHODS: We included 42 patients with MINOCA and 38 patients with INOCA. Endothelial function was assessed by measuring FMD% and nitroglycerin-mediated dilatation (NMD%) in the brachial artery. The plasma level of CT-1 was determined by solid-phase enzyme-linked immunosorbent assay. RESULTS: FMD% was significantly lower in MINOCA than in INOCA patients (6.45 ± 2.65 vs 8.94 ± 3.32, P < .001), without significant difference in NMD% (10.69 ± 3.19 vs 12.16 ± 3.69, P = .06). Plasma CT-1 levels were not significantly different: 40.1 pg/mL (22.5-102.1) vs 37.2 pg/mL (23.5-67.2), P = .53. CONCLUSION: Our results suggest worse ED in MINOCA than in INOCA patients, but demonstrated no difference in CT-1 levels between patients with stable and unstable ischemic heart disease and normal coronary arteries.

BACKGROUND: Transient ischemic attack (TIA) is a common neurovascular disorder associated with a higher risk of stroke within the first 24 h after the first event. Acute cerebral and arterial neuroimaging combined with long-term electrocardiography (ECG) monitoring have been proven to be useful in determining etiology. Cardio-embolism constitutes 20%-26% etiology of TIAs most of them with atrial fibrillation (AF). Investigation of AF after TIA is very important because oral anticoagulants can reduce the risk of subsequent stroke by two thirds. MATERIALS AND METHODS: The present study included 45 patients suffering from TIA with undetermined source according to the Trial of Org 10172 in Acute Stroke Treatment criteria; the control group (n = 45) was selected from the patients admitted to cardiology outpatient clinic with nonspecific complaints without cerebrovascular and/or cardiovascular disease. All patients underwent echocardiography and 24 h Holter ECG monitoring (HM). RESULTS: There was no significant difference between the patient group and the control group in terms of age and gender. Cholesterol, low-density lipoprotein and urea levels, left atrium diameters and the incidence of hypertension, coronary artery diseases, and AF were significantly higher in TIA group (P < 0.05). In the results of HM, there were six patients with AF in the study group, and in the control group, there was no patients with AF (P = 0.03). DISCUSSION AND CONCLUSION: In acute phase of TIA, 24 h HM is important for determining the etiology and selecting an appropriate treatment that can protect patients from subsequent strokes.
RESUMO
Transient contrast neurotoxicity is a rare but well-recognized complication of angiography that is due to neurotoxicity of the contrast agent. Patients with renal dysfunction may be inclined to develop contrast medium neurotoxicity due to delayed elimination of the contrast medium in renal metabolism. In this report, we present an unusual case of transient neurotoxicity in a patient with severe chronic kidney disease following percutaneous coronary intervention mimicking clinically and radiologically subarachnoid hemorrhage. The patient's clinical symptoms improved rapidly and fully recovered after hemodialysis and conservative treatment. We believe that performing early hemodialysis is an effective treatment to improve symptoms in end-stage renal disease patients with contrast-induced encephalopathy.
RESUMO
AIMS: Left bundle branch block (LBBB) causes a dyssynchronized contraction of left ventricle. This is a kind of regional wall-motion abnormality and measuring left ventricular ejection fraction (LVEF) by two-dimensional (2D) echocardiography could be less reliable in this particular condition. Our aim was to evaluate the role of dyssynchrony index (SDI), measured by three-dimensional (3D) echocardiography, in assessment of LVEF and left ventricular volumes accurately in patients with LBBB. METHODS AND RESULTS: In this case-control study, we included 52 of 64 enrolled participants (twelve participants with poor image quality were excluded) with LBBB and normal LVEF or nonischemic cardiomyopathy. Left ventricular ejection fraction (LVEF) and left ventricular volumes were assessed by 2D (modified Simpson's rule) and 3D (four beats full volume analysis) echocardiography and the impact of SDI on results were evaluated. In patients with SDI ≥6%, LVEF measurements were significantly different (46.00% [29.50-52.50] vs 37.60% [24.70-45.15], P < .001) between 2D and 3D echocardiography, respectively. In patients with SDI < 6%, there were no significant differences between two modalities in terms of LVEF measurements (54.50% [49.00-59.00] vs 54.25% [40.00-58.25], P = .193). LV diastolic volumes were not significantly different while systolic volumes were underestimated by 2D echocardiography, and this finding was more pronounced when SDI ≥ 6%. CONCLUSION: In patients with LBBB and high SDI (≥6%), LVEF values were overestimated and systolic volumes were underestimated by 2D echocardiography compared to 3D echocardiography.

OBJECTIVES: Blood pressure (BP) variability is associated with hypertensive (HT) target organ damage and cardiovascular events. The aim of this study was to investigate the relation between neutrophil to lymphocyte ratio (NLR) and BP variability in hypertensive and normotensive subjects. STUDY DESIGN: In this cross-sectional study, 150 subjects (63 male, mean age 52.1±5.2 years) were enrolled. In all patients, blood samples and 24-hour ambulatory blood pressure (BP) monitoring were obtained. According to 24-hour ambulatory BP results, participants were divided into four investigation categories. Group 1= Normotensive dipper (ND), Group 2= Normotensive non-dipper (NN), Group 3= HT dipper (HD), Group 4= HT non-dipper (HN). RESULTS: Highest NLR values were determined in the HN group (p=0.005 vs. ND, p=0.046 vs. NN and p<0.01 vs. HD). NLR values were similar among the ND, NN and HD groups (p>0.05, for all). NLR was correlated with night systolic blood pressure (SBP) (r=0.178, p=0.031), night diastolic blood pressure (DBP) (r=0.176, p=0.032) and BP variation rate (r=-0.246, p=0.003). Multiple linear regression analysis showed BP variation rate to be an independent predictor of high NLR value (ß=0.186, 95% CI=0.918-0.982, p=0.044). In ROC analysis, a level of NLR>2.7 predicted non-dipper HT with 83% sensitivity and 65% specificity (ROC area under curve: 0.653, 95% CI=0.565-0.741, p=0.001). CONCLUSION: In the present study, we found that NLR levels were significantly correlated with BP variability. The measurement of NLR may be used to indicate increased risk of HT-related adverse cardiovascular events.

Abnormal left ventricle (LV) geometric patterns are associated with an increased risk of vascular complications of hypertension (HT). The association between red-cell distribution width (RDW) and HT has been recently investigated; however, the relationship between abnormal LV geometric patterns and RDW has not been studied before. The aim of this study was to investigate the relationship between RDW and abnormal LV geometric patterns in patients with untreated essential HT. Measurements were obtained from 139 patients with untreated essential HT (mean age=51.3±16.3 years). Four different geometric patterns (NG, normal geometry; CR, concentric remodeling; EH, eccentric hypertrophy; CH, concentric hypertrophy) were determined according to the LV mass index (LVMI) and relative wall thickness (RWT). RDW, lipid parameters and other biochemical markers were measured in all patients. While the highest RDW values were detected in the CH group (P<0.05, for all), it was similar among the NG, CR and EH groups (P>0.05, for all). RDW was associated with age, LVMI and LV geometry in bivariate analysis (P<0.05, for all). In a receiver operating characteristic (ROC) curve analysis, a level of RDW>14.5 predicted CH with 81% sensitivity and 59% specificity. Age (beta=0.309, P=0.001), LV geometry type (beta=0.228, P=0.01) and RWT (beta=-0.278; P=0.25) were independent predictors of high RDW in multiple linear regression analysis. In conclusion, the highest RDW values were observed in the CH group in the untreated essential HT patients. RDW seems to be a useful tool for the prediction of end-organ damage in patients with untreated essential HT.

BACKGROUND: Recurrent pericardial effusion is often caused by pericardial metastases of extra-cardiac tumours. These effusions may be moderate to severe, leading to cardiac tamponade. The treatment is emergency pericardiocentesis but in spite of the initial success of that treatment, the effusions have high recurrence rates. Here we describe our experience of percutaneous balloon pericardiotomy (PBP) using the Inoue balloon for the management of three patients with malignant pericardial effusions secondary to lung cancer. METHODS: In our clinic, three patients with recurrent pericardial effusion secondary to lung cancer were treated with percutaneous pericardiotomy with an Inoue valvuloplasty balloon catheter through the subxiphoid approach. RESULTS: Successful drainage with balloon pericardiotomy was achieved in all patients without severe complications. In all cases, only one pericardial site was dilated at least three times. During the four to six months of follow up, there were no recurrences of the effusion or tamponade. All patients were still alive. CONCLUSIONS: In our experience, PBP with the Inoue balloon appears to be a simple and safe procedure with a high success rate. PBP is an effective method for the management of patients with recurrent, large, malignant pericardial effusions.

Coronary artery dissection is a rare complication after blunt chest trauma. Patients usually present with sudden death and the diagnosis is frequently missed. In this report, we present a case of a 46-year-old with a hyperacute anterior wall myocardial infarction after blunt chest trauma. Diagnostic coronary angiography showed total occlusion of the left anterior descending coronary artery (LAD) starting at the takeoff of the vessel from the left main coronary artery (LMCA). A bare-metal stent was immediately deployed at the proximal LAD and TIMI 3 flow was achieved; however post-procedural images revealed no satisfactory results. A proximal dissection and intraluminal thrombus extending to the LMCA was observed. Because of the proximity of the lesion to the LMCA, re-intervention was considered to be risky and urgent coronary artery bypass grafting (CABG) was planned. Coronary artery stenting is the advised treatment modality for coronary occlusion after blunt chest trauma. However, post-traumatic percutaneous coronary intervention was sometimes considered to be risky because of the anatomic features of the lesion. Timing is cardinal in achieving early reperfusion in the course of myocardial infarction after blunt chest trauma and CABG should be the preferred procedure for initial reperfusion treatment especially in proximal LAD dissections with subsequent thrombus formation leading to total occlusion of the artery.

AIMS: The aim is to research the relationship between the degree of depression-malnutrition and inadequate volume control. METHODS: The mean age of the 52 patients was 55+/-14.6 years. Malnutrition score [subjective global assessment (SGA)] and depression score [Taiwanese Depression Questionnaire (TDQ)] of each chronic hemodialysis (CHD) patient were calculated. Then an echocardiographic assessment was carried out with the same device 1 day before the second HD session of the week. The 24 h blood pressure monitoring was performed 1 day before the second HD session of the week. RESULTS: TDQ scores (TDQS) were >or=19 in 41 and <19 in 11 patients. TDQS was found to be significantly high in women (p=0.01) who were older than 40 years (p=0.03) and who have low family income (p=0.03). TDQS was found to be significantly correlated with HD duration (p=0.034), vena cava inferior collapse index (p=0.02), malnutrition score (p=0.011), residual renal function (ml/day) (p=0.03), level of albumin (p=0.0009), and iron (p=0.015). A positive correlation was detected between TDQS and the ratio of mean nighttime blood pressure/mean daytime blood pressure (p=0.005, r=0.394). Depression score was found to be significantly different between normal geometry and left ventricular hypertrophy (eLVH), concentric remodeling and eLVH, and concentric LVH and eLVH. CONCLUSIONS: The results show that lesser degrees of nocturnal dip and eLVH are associated with increased degrees of depression, implying that hypervolemia is strongly associated with depression and might be a component of strong relationships involving malnutrition, inflammation, and atherosclerosis in CHD patients.

BACKGROUND: The aim of this study is to investigate the relationship between the degree of malnutrition and inadequate volume control evidenced by echocardiography. METHODS: In this study 72 chronic hemodialysis patients were investigated in a cross-sectional manner. The malnutrition score was calculated using Subjective Global Assessment. M-mode echocardiography was performed in all patients. RESULTS: The highest malnutrition score (23.2 +/- 1.5 points) and lowest vena cava inferior collapse index (35 +/- 2%) were observed in the eccentric left ventricular hypertrophy group. The malnutrition index was found to be in positive relationship with the left atrium diameter and index, left ventricular mass and index, and left ventricular end-diastolic diameter. On the other hand, a negative correlation was detected with the vena cava inferior collapse index. When all parameters that were found to be related to malnutrition were assessed by multivariate analyses, a statistically significant relation was found between the left ventricular end-diastolic diameter and the malnutrition index. CONCLUSION: The results of our study show that the progressive worsening of the nutritional status follows a parallel course along with the deterioration in the echocardiographic parameters concerning hypervolemia. This in turn suggests that increasing degrees of malnutrition are associated with more profound derangements in the volume status. Volume excess might be a mechanism explaining the increased mortality and morbidity caused by malnutrition in hemodialysis patients. Owing to its cross-sectional design, this study cannot provide unequivocal evidence regarding the cause and effect relationship between volume overload and malnutrition in hemodialysis patients.

In this study, we investigated the effects of both 25 and 50 mg daily doses of rofecoxib on the endothelial functions of patients with coronary artery disease (CAD). For this purpose, 34 patients with documented severe CAD and who were under aspirin treatment (300 mg/day) were randomized to receive 4 weeks of treatment with a placebo (n = 10, group I), rofecoxib 25 mg/day (n = 12, group II), and rofecoxib 50 mg/day (n = 12, group III). Brachial artery vasodilator responses were measured in order to evaluate endothelial function. The percentage of change in endothelial-dependent vasodilation in groups I, II, and III were similar at the baseline level and showed no significant change after treatment (6.2+/-3.9% vs. 5.9+/-3.1% and 5.8+/-3.3% vs. 5.6+/-3.8% and 6.1+/-4.5% vs. 5.8+/-4.1%, respectively; P > 0.05). Compared with the baseline, endothelium-independent vasodilatation, as assessed by nitroglycerine (NTG), remained unchanged after the treatment period (11.2+/-6.9% vs. 10.3+/-7.1% and 11.2+/-6.3% vs. 9.9+/-5.1% and 9.5+/-4.9% and 8.8+/-4.6%, respectively; P> 0.05). Treatment with both doses also showed no significant effects on high-sensitivity C-reactive protein (hs-CRP) levels and resting arterial diameters (P > 0.05). In conclusion, 4 weeks of treatment with standard and high doses of rofecoxib showed no significant effects on either endothelial-dependent or independent vasodilator response or plasma hs-CRP levels in patients with severe CAD taking concomitant aspirin.
