RESUMEN
Pericardial cyst is a rare congenital anomaly that is usually diagnosed during evaluation for right-sided heart failure. We report a 50-year-old man with a primary diagnosis of ST-segment elevation myocardial infarction at admission, whose emergent angiography revealed a calcific mass close to right coronary artery. Further analysis of the mass with computed tomography and three-dimensional echocardiography revealed a giant pericardial cyst causing partial obstruction of superior vena cava. Unlike previous cases reported, the patient had no symptoms compatible with right-sided heart failure.

The relationship between epicardial adipose tissue (EAT) and coronary artery disease has been predominantly demonstrated in the last two decades. The aim of this study was to investigate the predictive value of EAT thickness on ST-segment resolution that reflects myocardial reperfusion in patients undergoing primary percutaneous coronary intervention (pPCI) for acute ST-segment elevation myocardial infarction (STEMI). The present study prospectively included 114 consecutive patients (mean age 54 ± 10 years, range 35-83, 15 women) with first acute STEMI who underwent successful pPCI. ST-segment resolution (ΔSTR) <70 % was accepted as ECG sign of no-reflow phenomenon. The EAT thickness was measured by two-dimensional echocardiography. EAT thickness was increased in patients with no-reflow (3.9 ± 1.7 vs. 5.4 ± 2, p = 0.001). EAT thickness was also found to be inversely correlated with ΔSTR (r = -0.414, p = 0.001). Multivariate logistic regression analysis demonstrated that EAT thickness independently predicted no-reflow (OR 1.43, 95 % CI 1.13-1.82, p = 0.003). Receiver operating characteristic curve analysis demonstrated good diagnostic accuracy for EAT thickness in predicting no-reflow [area under curve (AUC) = 0.72, 95 % CI 0.63-0.82, p < 0.001]. In conclusion, increased EAT thickness may play an important role in the prediction of no-reflow in STEMI treated with pPCI.

BACKGROUND: Management of aortic regurgitation depends on the assessment for severity. Echocardiography remains as the most widely available tool for evaluation of aortic regurgitation. In this manuscript, we describe a novel parameter, jet length/velocity ratio, for the diagnosis of severe aortic regurgitation. METHODS AND RESULTS: A total of 30 patients with aortic regurgitation were included to this study. Severity of aortic regurgitation was assessed with an aortic regurgitation index incorporating five echocardiographic parameters. Jet length/velocity ratio is calculated as the ratio of maximum jet penetrance to mean velocity of regurgitant flow. Jet length/velocity ratio was significantly higher in patients with severe aortic regurgitation (2.03 ± 0.53) compared to patients with less than severe aortic regurgitation (1.24 ± 0.32, P < 0.001). Correlation of jet length/velocity ratio with aortic regurgitation index was very good (r(2) = 0.86) and correlation coefficient was higher for jet length/velocity ratio compared to vena contracta, jet width/LVOT ratio and pressure half time. For a cutoff value of 1.61, jet length/velocity ratio had a sensitivity of 92% and specificity of 88%, with an AUC value of 0.955. CONCLUSIONS: Jet length/velocity ratio is a novel parameter that can be used to assess severity of chronic aortic regurgitation. Main limitation for usage of this novel parameter is jet impringement to left ventricular wall.

PURPOSE: Ventricular noncompaction/hypertrabeculation (NC/HT) is a rare form of congenital cardiomyopathy. We aimed to investigate the presence of serum tenascin-C (TN-C) in adult patients with NC/HT and evaluate its value. METHODS AND RESULTS: Serum TN-C levels were measured by ELISA in 50 NC/HT patients both with/without systolic dysfunction and in 23 normal controls. Systolic dysfunction was defined as ejection fraction (EF) ≤ 40. Mann-Whitney U-test and ROC curve analysis were done. Of 49 NC/HT patients, 24 (49%) patients had systolic dysfunction (mean age 36 ± 15) and 25 patients (51%) had normal systolic function (mean age 36 ± 17). The ages between groups were not different. The mean levels of serum TN-C in patients with or without systolic dysfunction were 26 ± 10 ng/mL and 26 ± 8 ng/mL respectively, compared to normal controls, 7 ± 2 ng/mL (P < 0.001). No significance was observed between 2 groups of NC/HT patients regarding TN-C levels (P = 0.8). The ROC curve analysis revealed that a TN-C value of 11.7 ng/mL identified patients with NC/HT with 100% sensitivity and specifity. CONCLUSION: High serum TN-C levels are present in adult NC/HT cardiomyopathy even when left ventricular systolic function remains normal. Also, serum TN-C levels could be regarded as a candidate biomarker in the diagnosis of NC/HT which needs to be tested in larger prospective studies.

BACKGROUND: Aortic dissection is an important cause of acute chest pain that should be rapidly diagnosed, as mortality increases with each hour this condition is left untreated. The diagnosis can be challenging, especially if concomitant myocardial infarction is present. Echocardiography is an important tool for the differential diagnosis. OBJECTIVES: To stress the importance of recognizing aortic regurgitation for the differentiation of myocardial infarction and aortic dissection. CASE REPORT: An 80-year-old woman was admitted to our hospital with chest pain that was diagnosed as inferior and lateral wall myocardial infarction based on electrocardiographic findings. The diagnosis was reevaluated when aortic regurgitation was detected on echocardiography. Closer inspection of the ascending aorta revealed a dissection flap as the cause of aortic regurgitation. CONCLUSION: Detection of aortic regurgitation in a patient with myocardial infarction and normal valves should prompt the search for a possible aortic dissection, whether or not the dissection flap can be visualized.

INTRODUCTION: Pulmonary vasculature is affected in patients with chronic pulmonary obstructive disease (COPD). As a result of increased pulmonary resistance, right ventricular morphology and function are altered in COPD patients. High altitude and related hypoxia causes pulmonary vasoconstriction, thereby affecting the right ventricle. We aimed to investigate the combined effects of COPD and altitude-related chronic hypoxia on right ventricular morphology and function. MATERIALS AND METHODS: Forty COPD patients living at high altitude (1768 m) and 41 COPD patients living at sea level were enrolled in the study. All participants were diagnosed as COPD by a pulmonary diseases specialist depending on symptoms, radiologic findings and pulmonary function test results. Detailed two-dimensional echocardiography was performed by a cardiologist at both study locations. RESULTS: Oxygen saturation and mean pulmonary artery pressure were higher in the high altitude group. Right ventricular end diastolic diameter, end systolic diameter, height and end systolic area were significantly higher in the high altitude group compared to the sea level group. Parameters of systolic function, including tricuspid annular systolic excursion, systolic velocity of tricuspid annulus and right ventricular isovolumic acceleration were similar between groups, while fractional area change was significantly higher in the sea level groups compared to the high altitude group. Indices of diastolic function and myocardial performance index were similar between groups. CONCLUSION: An increase in mean pulmonary artery pressure and right ventricular dimensions are observed in COPD patients living at high altitude. Despite this increase, systolic and diastolic functions of the right ventricle, as well as global right ventricular performance are similar in COPD patients living at high altitude and sea level. Altitude-related adaptation to chronic hypoxia could explain these findings.

OBJECTIVES: The relationship between markers of myocardial ischemia and severity of coronary artery disease (CAD) has been investigated in several studies. In this study, we examined the relationship between severity of CAD and heart-type fatty acid-binding protein (H-FABP), a new marker of ischemia in patients with non-ST-segment elevation acute coronary syndrome (ACS). STUDY DESIGN: This prospective study comprised 49 patients who were referred to the emergency room with a diagnosis of non-ST elevation myocardial infarction. Troponins, creatine kinase-MB, lactate dehydrogenase, and aspartate aminotransferase levels were measured quantitatively, while blood H-FABP levels were measured qualitatively in the 4th-8th hour from the onset of symptoms. All patients underwent coronary angiography within 72 hours after admission. Clinical and coronary angiographic characteristics of patients with positive and negative values of H-FABP were compared. Gensini and SYNTAX scores were used to determine the severity of CAD. RESULTS: There were no statistically significant differences in mean age, gender distribution, risk factors for CAD, ischemic changes on ECG, or Gensini and SYNTAX scores between the H-FABP-negative and -positive groups (p>0.05). The duration of chest pain in the H-FABP-positive group was significantly longer than in the negative group (p<0.001). Troponin, CK-MB, and AST levels as well as thrombolysis in myocardial infarction (TIMI) risk scores were found to be significantly higher in the H-FABP-positive group (p<0.05). CONCLUSION: H-FABP is a useful marker for the diagnosis and risk evaluation of patients with non-ST elevation ACS. However, it is insufficient in evaluating the severity of CAD.

INTRODUCTION: Chronic inflammation promotes aortic valve calcification. It is known that epicardial fat is a source of inflammation. The aim of this study was to investigate the relationship between epicardial fat thickness, cardiac conduction disorders and outcomes in patients undergoing transcatheter aortic valve implantation (TAVI). METHODS: During a three-year period, 45 patients with severe aortic stenosis who underwent TAVI were recruited to the study. Data were collected retrospectively. Epicardial fat was defined as the adipose tissue between the epicardium and the visceral pericardium. Mean epicardial fat thickness was determined by multi-slice computed tomography, which was performed before the procedure. RESULTS: The average thickness of epicardial fat was 13.06 ± 3.29 mm. This study failed to reveal a significant correlation between epicardial fat thickness and post-procedural left bundle branch block, right bundle branch block, paravalvular aortic regurgitation and pacemaker implantation rates (p > 0.05). CONCLUSIONS: The results of this study failed to show a significant relationship between epicardial fat thickness, cardiac conduction disorders and outcomes, however further studies with larger sample numbers are required to explore the relationship.

BACKGROUND: Conflicting datas exist regarding the outcomes of primary percutaneous coronary intervention (PCI) for ST-segment elevation myocardial infarction (STEMI) when the intervention is performed during night hours. METHODS AND RESULTS: 2,644 consecutive patients with STEMI (mean age 56.7 +/- 11.9, years, 2,188 male) undergoing primary PCI between October 2003 and March 2008 were retrospectively enrolled into this study (single high-volume center: >3,000 PCIs/year). Day time was defined according to intervention between 08:00 am and 06:00 pm and night as intervention time between 06:00 pm and 08:00 am. 1,141 patients (43.2%) were treated during the day and 1,503 (56.8%) at night. The baseline characteristics of both groups were similar except for more frequent hypertension (42.6 vs. 36.5%; P = 0.002), women (19.7 vs. 15.4%; P = 0.003), and old (> or =75 y) patients (9.6 vs. 7.4; P = 0.046) in the day time group. Compared with those treated during night time, day time patients had longer angina-reperfusion times (mean, 205 vs. 188 minutes, P = 0.016). Door-to-balloon times were similar (P = 0.87), and less than 90 minutes in both groups. There were no differences concerning clinical events and PCI success between the two groups. Hospital mortality was 6.1% during the day and 5.2% during the night (OR 0.98, 95% CI 0.7-1.36; P = 0.89). The median follow-up time was 21 months. The Kaplan-Meier survival plot for long-term cardiovascular death was not different for both groups (P = 0.78). In-hospital and long-term cardiovascular mortality was also similar in shock and nonshock subgroups. CONCLUSIONS: Primary PCI can be performed safely during the night at a high-volume PCI center with suitable and effective organization of cardiology department and catheterisation laboratory with 24 hours per day, 7 days per week onsite staffing.

OBJECTIVE: A predictive role of serum Pentraxin 3 (PTX3) for short-term adverse cardiovascular events including mortality in acute myocardial infarction (AMI) was reported in recent studies. The aim of the study was to investigate long-term prognostic significance of serum PTX3 in an AMI with 5-year follow-up period in this study. METHODS: In this prospective study, 140 patients, who were admitted to the emergency department between January 2011 and December 2011 with acute chest pain and/or dyspnea and diagnosed with AMI and 60 healthy controls were included. PTX3 levels were measured at admission by using an ELISA method. The study group was divided into tertiles on the basis of admission PTX3 values: the high-PTX3 group (≥4.27 ng/mL), the middle-PTX3 groups (4.27-1.63 ng/mL), and the low-PTX3 group (≤1.63 ng/mL). RESULTS: PTX3 level was significantly more greatly increased in the AMI group than in the controls (2.27±0.81 vs. 0.86±0.50 ng/mL, p<0.001). PTX3 level was found to be significantly positively correlated with TIMI score (r=0.368, p=0.037), high sensitive C-reactive protein (hsCRP) (r=0.452, p=0.024), pro-BNP (r=0.386, p=0.029), troponin I (r=0.417, p=<0.001), and GRACE score (r=0.355, p=0.045), and negatively correlated with HDL cholesterol (r=-0.203, p=0.016) and LVEF (r=-0.345, p=0.028). In multivariate analysis, PTX3 (OR=1.12, 95% CI 1.04-1.20; p=0.001) was a significant independent predictor of long-term cardiovascular mortality, after adjusting for other risk factors. CONCLUSION: PTX3 is a novel biomarker that may help to identify high risk individuals with AMI, who are potentially at risk of early major adverse cardiovascular events including mortality in the long-term period.

OBJECTIVE: The present study was designed to evaluate the characteristics of pulmonary hypertension (PH) and adult cardiology practice patterns for PH in our country. METHODS: We evaluated preliminary survey data of 1501 patients with PH (females, 69%; age, 44.8±5.45) from 20 adult cardiology centers (AdCCs). RESULTS: The average experience of AdCCs in diagnosing and treating patients with PH was 8.5±3.7 years. Pulmonary arterial hypertension (PAH) was the most frequent group (69%) followed by group 4 PH (19%), group 3 PH (8%), and combined pre- and post-capillary PH (4%). PAH associated with congenital heart disease (APAH-CHD) was the most frequent subgroup (47%) of PAH. Most of the patients' functional class (FC) at the time of diagnosis was III. The right heart catheterization (RHC) rate was 11.9±11.6 per month. Most frequently used vasoreactivity agent was intravenous adenosine (60%). All patients under targeted treatments were periodically for FC, six-minute walking test, and echo measures at 3-month intervals. AdCCs repeated RHC in case of clinical worsening (CW). The annual rate of hospitalization was 14.9±19.5. In-hospital use of intravenous iloprost reported from 16 AdCCs in CWs. Bosentan and ambrisentan, as monotreatment or combination treatment (CT), were noted in 845 and 28 patients, respectively, and inhaled iloprost, subcutaneous treprostinil, and intravenous epoprostenol were noted in 283, 30, and four patients, respectively. Bosentan was the first agent used for CT in all AdCCs and iloprost was the second. Routine use of antiaggregant, anticoagulant, and pneumococcal and influenza prophylaxis were restricted in only two AdCCs. CONCLUSION: Our nationwide data illustrate the current status of PH regarding clinical characteristics and practice patterns.

BACKGROUND: The Zwolle score (Zs) is a validated risk score used to identify low-risk patients with acute ST-elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention (PCI). The Syntax score (Ss) is an angiographic score that evaluates the complexity of coronary artery disease. AIM: We aimed to create a simple risk score by combining these two scores for risk stratification in patients with STEMI undergoing primary PCI. METHODS: 299 consecutive STEMI patients (mean age 57.4 ± 11.7 years, 240 men) who underwent primary PCI were prospectively enrolled into the present study. The study population was divided into tertiles based on admission Zs and Ss. A high Zs (> 3) and high Ss (> 24) were defined as values in the third tertiles. A low Zs and low Ss were defined as values in the lower two tertiles. Patients were then classified into four groups: high Zs and high Ss (HZsHSs, n = 26), high Zs and low Ss (HZsLSs, n = 29), low Zs and high Ss (LZsHSs, n = 48), and low Zs and low Ss (LZsLSs, n = 196). In-hospital cardiacoutcomes were then recorded. RESULTS: In-hospital cardiovascular mortality was higher in HZsHSs (50%) compared to the HZsLSs (27.5%), LZsHSs (0%), and LZsLSs (0.5%) groups. After adjustment for potentially confounding factors, HZsHSs (OR 77.6, 95% CI 6.69-113.1, p = 0.001), and HZsLSs (OR 28.9, 95% CI 2.77-56.2, p = 0.005) status, but not LZsHSs and LZsLSs status, remained independent predictors of in-hospital cardiovascular mortality. CONCLUSIONS: STEMI patients with HZsHSs represent the highest risk population for in-hospital cardiovascular mortality.

BACKGROUND: Resistin is a novel adipokine that is suggested to be involved in inflammatory conditions and atherosclerosis. AIM: To investigate the prognostic importance of resistin in acute myocardial infarction (AMI) patients. METHODS: Resistin levels were measured in a population of 132 patients with AMI, of whom 72 (54%) had a diagnosis of ST elevation myocardial infarction (STEMI), and 60 (46%) had non-ST elevation myocardial infarction (NSTEMI). Thirty-three consecutive subjects who were referred to elective coronary angiography due to chest pain evaluation with normal coronary angiograms served as controls. All patients were followed-up for the occurrence of major adverse cardiac events (MACE). RESULTS: There was a significant increase in serum resistin levels in patients with AMI compared to controls (3.71 ± 4.20 vs. 2.00 ± 1.05, p = 0.001, respectively). However, serum resistin levels were similar in patients with STEMI and NSTEMI. (4.26 ± 5.11 vs. 3.06 ± 2.64, p = 0.49, respectively). The patients with MACE had significantly higher levels of serum resistin levels compared to either the AMI or the control group (6.35 ± 5.47, p = 0.005, respectively). Logistic regression analysis revealed that resistin, left ventricular ejection fraction, and coronary artery bypass graft were independent predictors of MACE in AMI patients (OR = 1.11, 95% CI 1.01-1.22, p = 0.03 and OR = 3.84, 95% CI 1.26-11.71, p = 0.018, respectively). CONCLUSIONS: Serum resistin level was increased in patients with AMI and constituted a risk factor for MACE in this group.

We prospectively assessed the value of estimated glomerular filtration rate (eGFR) by the Modification of Diet in Renal Disease (MDRD) and Cockcroft-Gault (C-G) equations in predicting inhospital adverse outcomes after primary coronary intervention for acute ST-segment elevation myocardial infarction. We classified 647 patients into 3 categories according to eGFR, <60, 60 to 90, and >90 mL/min/1.73 m(2). The eGFRC-G classified 17 patients in the >90 mL/min/1.73 m(2) subgroup and 6 and 11 patients in the 60 to 90 and <60 mL/min/1.73 m(2) subgroups, respectively. In multivariate analysis, patients with eGFRC-G < 60 mL/min/1.73 m(2) had 19.5-fold (95% confidence interval [CI] 1.55-178) higher mortality risk and 5.48-fold (95% CI 1.75-24.21) higher major adverse cardiac events risk compared to patients with eGFRC-G >90 mL/min/1.73 m(2) (P = .01 and P = .01, respectively); the eGFRMDRD was not predictive. Although the MDRD equation more accurately estimates GFR in certain populations, the CG formula may be a better predictor of adverse events.

Ventricular hypertrabeculation/noncompaction is a morphologic and functional anomaly of myocardium characterized by prominent trabeculae accompanied by deep recessus. Dilated cardiomyopathy with left ventricular failure is observed in these patients, while the cause or pathophysiologic nature of this complication is not known. Anti-troponin antibodies are formed against circulating cardiac troponins after an acute coronary event or conditions associated with chronic myocyte necrosis, such as dilated cardiomyopathy. In present study, we aimed to investigate cardiac troponins and anti troponin autoantibodies in ventricular noncompaction/hypertrabeculation patients with/without reduced ejection fraction. A total of 50 patients with ventricular noncompaction and 23 healthy volunteers were included in this study. Noncompaction/hypertrabeculation was diagnosed with two-dimensional echocardiography using appropriate criteria. Depending on ejection fraction, patients were grouped into noncompaction with preserved EF (LVEF >50%, nâ=â24) and noncompaction with reduced EF (LVEF <35%, nâ=â26) groups. Troponin I, troponin T, anti-troponin I IgM and anti-troponin T IgM were measured with sandwich immunoassay method using a commercially available kit. Patients with noncompaction had significantly higher troponin I (28.98±9.21 ng/ml in NCNE group and 28.11±10.42 ng/ml in NCLE group), troponin T (22.17±6.97 pg/ml in NCNE group and 22.78±7.76 pg/ml in NCLE group) and antitroponin I IgM (1.92±0.43 µg/ml in NCNE group and 1.79±0.36 µg/ml in NCLE group) levels compared to control group, while antitroponin T IgM and IgG were only elevated in patients with noncompaction and reduced EF (15.81±6.52 µg/ml for IgM and 16.46±6.25 µg/ml for IgG). Elevated cardiac troponins and anti-troponin I autoantibodies were observed in patients with noncompaction preceding the decline in systolic function and could indicate ongoing myocardial damage in these patients.
