Acute myocardial infarction and polycythemia rubra vera: The double effect of treatment with hydroxyurea.

We report a case of acute myocardial infarction in a patient with polycythemia rubra vera, who has been treated with hydroxyurea. The patient presented with chest pain extending to both arms accompanied by nausea and sweating. Hemoglobin was 18.1 mg/dL, hematocrit 53.2%, white blood cells 9600/mm³, and platelets 745,000/mm³. The levels of specific cardiac injury markers were increased, troponin I increased to 110 ng/mL and creatine kinase-MB to 361 U/l, respectively. Electrocardiography showed sinus rhythm with ST-segment elevation in leads V2-6, D1, and aVL as well as ST depression in D2, D3 and aVF. Echocardiography demonstrated hypokinesis of the interventricular septum and lateral wall with mildly reduced left ventricle (LV) ejection fraction (EF≈45%). Coronary angiography revealed proximal-LAD subtotal occlusion and 80% mid-LAD stenosis with distal-LAD vasospasm. Percutaneous coronary intervention was performed with a drug-eluting stent in mid- and proximal-LAD. Hypercoagulable state of polycythemia rubra vera may be complicated with acute myocardial infarction, in addition to the vasospastic effect and endothelium lesions of hydroxyurea regardless its favorable effect as a standard therapy.

Large intercoronary communication between the right coronary artery and the left circumflex artery in a patient with late stent thrombosis: A case report.

Intercoronary communication (ICC) is a very rare coronary artery anomaly that connects directly 2 coronary arteries. This anastomosis is found between 2 nonobstructed coronary arteries with unidirectional or bidirectional blood flow. We report a case of a large ICC between the right coronary artery and the left circumflex artery in a patient with late stent thrombosis. The electrocardiogram showed ST-segment elevation in the anterior leads. The echocardiography investigation revealed hypokinesis in the proximal, medial and apical segments of the interventricular septum and anterior wall as well as the apex. During invasive coronary examination a large ICC between the left circumflex artery (LCx) and the right coronary artery (RCA) was found. Furthermore, coronary angiography demonstrated proximal occlusion (stent thrombosis) of the left anterior descending artery (LAD), prompting the utilization of percutaneous intervention with a drug-eluting stent. The presence of a large intercoronary communication is an exceedingly uncommon anomaly of the coronary arteries, which has the potential to induce myocardial ischemia. In individuals with obstructive coronary artery disease, this anomaly can further worsen the existing condition.

Association between apelin-12 and creatine kinase-MB, depending on success of reperfusion in STEMI patients.

BACKGROUND: Acute myocardial infarction is characterised by an imbalance in the supply and demand of oxygen in the heart. It requires urgent reperfusion, and poor outcomes are attributed to myocardial ischaemia-reperfusion injury. We aimed to evaluate the association between apelin-12 levels and creatine kinase-MB activity in predicting the effectiveness of reperfusion therapy in ST-segment elevation myocardial infarction (STEMI) patients. METHODS: In this study we included 72 patients with the following criteria: chest pain suggestive of myocardial ischaemia for at least 30 minutes, an electrocardiogram with ST-segment elevation (measured at the J-point) ≥ 2 mm in leads V2-V3 and/or ≥ 1 mm in the other leads, rise of specific biomarkers such as cardiac troponin and the MB fraction of creatine kinase (CK-MB), and those who underwent reperfusion therapy. Blood samples for the measurement of apelin-12 and creatine kinase-MB were collected 12 hours after the reperfusion therapy. RESULTS: In patients with thrombolysis in myocardial infarction (TIMI) flow grade ≤ 2, the median of the apelin-12 level was 1.80 ng/ml (0.46-9.20), and with TIMI flow 3, it was 5.76 ng/ml (1.14-15.2). Variability was observed in the apelin values (Mann-Whitney test) based on TIMI flow grade (p < 0.001), while no variability was observed for creatine kinase-MB (p < 0.18). The degree of association between apelin-12 and creatine kinase-MB levels was analysed with Pearson's correlation, enabling us to determine patients with successful reperfusion (determined as TIMI flow 3) (p < 0.004), and those with unsuccessful reperfusion (with TIMI flow ≤ 2) (p = 0.86). CONCLUSION: In STEMI patients undergoing reperfusion therapy, Apelin-12 level was associated with creatine kinase-MB activity according to the success of the reperfusion.

Primary percutaneous coronary intervention on split left coronary artery: Two case reports.

The split left coronary artery (LCA) is an anomaly of coronary arteries connection related to the aorta, presenting more often in patients who underwent invasive coronary angiography compared to coronary computed tomography angiography. Although this anomaly causes no hemodynamic impairment, failure to recognize may lead to incorrect diagnosis and prolonged procedures during acute myocardial infarction resulting in serious complications. We report 2 cases of split left coronary artery presenting with acute myocardial infarction who underwent primary percutaneous coronary interventions (pPCI) with excellent outcomes. In the both cases, electrocardiogram demonstrated ST-segment elevation and cardiac biomarkers were increased. Also, before coronary angiography in both patients echocardiographic examination was performed revealing hypokinesis who corresponded with the territory of occluded coronary arteries. During invasive further coronary examinations split left artery was found, besides the culprit lesion in the left anterior descending artery (LAD). Successful percutaneous stenting was performed on LAD achieving TIMI flow grade 3 in both cases. Prompt recognition of split LCA in the setting of acute myocardial infarction during pPCI, it is essential to achieve appropriate treatment and avoid potential clinical consequences.

Coronary to pulmonary artery fistula associated with significant coronary atherosclerosis and severe aortic valve stenosis: A Case Report.

Coronary artery fistulas are anomalous connections between one or two coronary arteries with either a cardiac chamber or any major blood vessels (coronary sinus, superior vena cava, pulmonary veins and pulmonary artery). It is rarely reported, occurring only in 0.1%-0.2% of patients who undergo coronary angiography. We report a very rare case where myocardial ischaemia may have resulted from the presence of coronary artery fistula, significant coronary artery stenosis and severe aortic valve stenosis. Transthoracic echocardiography showed severe aortic stenosis, while coronary angiography showed a tortuous coronary artery fistula originating from the proximal left anterior descending artery, with a single opening in the main pulmonary artery. Angiography also showed significant stenosis in the middle of the left anterior descending artery. Coronary artery fistula with concomitant significant coronary atherosclerosis and severe aortic stenosis requires optimal therapeutic planning.

Immature teratoma mimicking pulmonary stenosis: a case report.

BACKGROUND: Immature teratoma in a mediastinal location is a rare disease that might present as a valve pathology. Germ cell tumors with mediastinal locations account for up to 6% of immature teratoma cases. We present a case of an immature teratoma located primarily in the anterior mediastinum that manifested solely through symptoms of pulmonary stenosis. CASE PRESENTATION: We report a case of a 20-year-old white man with an immature teratoma who presented with progressive exertional dyspnea. During a cardiac examination, an ejection systolic murmur was observed, and echocardiography findings at an Emergency Centre revealed high velocity flow at the level of the pulmonary artery, indicating pulmonary stenosis. He was hospitalized in our Cardiology Department for further investigation. A chest X-ray revealed a mediastinal mass, and repeated echocardiography indicated the presence of a large mediastinal mass compressing his main pulmonary artery. Magnetic resonance imaging confirmed the tumor in the mediastinum, and a histopathological diagnosis of immature teratoma was established following biopsy. CONCLUSION: Immature teratoma causing cardiac-related complaints might shift the diagnosis toward cardiovascular diseases, thus requiring prompt examination by standard and sophisticated methods to clarify the diagnosis.

Impact of the National Population Register in Improving the Health Information System of Malignant Diseases in Kosova.

INTRODUCTION: Malignant diseases are serious socio-medical problem, being that they cause grave problems in terms of health, social and economic perspective to an individual, in particular, and society in general. A proper reporting and monitoring system enables adequate calculation of indicators and evidence based decision making. AIM: The study aims to examine the appearance of malignancies diagnosed and reported in Kosovo for a three years period: 2012, 2013, and 2014 by its modalities such as by the years of appearance, gender, age, and most frequent types of malignancies. MATERIAL AND METHODS: The study is a retrospective cohort research whereas source data we used are reports of malignant diseases from National Cancer Register (NCR) in the Health Information System (HIS) at the National Institute of Public Health of Kosova (NIPHK). RESULTS AND DISCUSSIONS: In Kosova during years 2012, 2013 and 2014 a total of 7437 cases of malignant diseases were reported; in 2012 were 31%, in 2013 were 24.3%, and during 2014 higher number of cases were reported, 3320 or 44.6%. During the reporting period, the appearance of malignant diseases in both sexes is about equal, with a light predominance of male cases with 50.8% (or 3780 cases), while by age group were represented with the elderly, from ages 50 to 79 years with 5111 cases or 68.8% of total malignancies. CONCLUSION: The highest number of malignant diseases was reported during year 2014 due to better reporting through HIS and NCR. Malignancies attacked both genders equally, whereas the most common types of malignancies were: melanoma and other malignant neoplasms of the skin, malignant diseases of the respiratory and intrathoracic organs, digestive tract, breast and female genital tract. The most affected the older ones.

Influence of apelin-12 on troponin levels and the rate of MACE in STEMI patients.

BACKGROUND: During acute myocardial infarction, phosphorylated TnI levels, Ca2+ sensitivity and ATPase activity are decreased in the myocardium, and the subsequent elevation in Ca2+ levels activates protease I (caplain I), leading to the proteolytic degradation of troponins. Concurrently, the levels of apelin and APJ expression are increased by limiting myocardial injury. METHODS: In this prospective observational study, 100 consecutive patients with ST-elevation acute myocardial infarction were included. Patients meeting the following criteria were included in our study: (1) continuous chest pain lasting for >30 min, (2) observation of ST-segment elevation of more than 2 mm in two adjacent leads by electrocardiography (ECG), (3) increased cardiac troponin I levels, and (4) patients who underwent reperfusion therapy. We evaluated the levels of apelin-12 and troponin I on the first and seventh days after reperfusion therapy in all patients. RESULTS: Apelin-12 was inversely correlated with troponin I levels (Spearman's correlation = -0.40) with a p value <0.001. There was variability in the apelin values on the seventh day (Kruskal-Wallis test) based on major adverse cardiac events (MACE) (p = 0.012). Using ROC curve analyses, a cut-off value of >2.2 for the association of apelin with MACE was determined, and the AUC was 0.71 (95% CI, 0.58-0.84). Survival analysis using the Kaplan-Meier method showed a lower rate of MACE among patients with apelin levels >2.2 (p = 0.002), and the ROC curve analysis showed a statistically significant difference in the area under the curve (p = 0.004). CONCLUSION: The influence of apelin levels on troponin levels in the acute phase of STEMI is inversely correlated, whereas in the non-acute phase, low apelin values were associated with a high rate of MACE.

Lower Body Weight in Men, an Epidemiological Predictor of Enlarged Left Atrium in Sinus Rhythm Patients with Dilated Heart.

BACKGROUND/AIMS: The source of thrombi in patients with dilated cardiomyopathy is not necessarily from the dilated left ventricle. Left atrium (LA) and left atrial appendage (LAA) might be in charge for relatively high rate of systemic embolizations in these patients. The main aim of our study was to identify epidemiological predictors in sinus rhythm patients with dilated heart for LA and LAA dilation and/or dysfunction. PATIENTS AND METHODS: This was a prospective cross-sectional study conducted from 2009 to 2014 in 101 sinus rhythm patients with dilated heart. We excluded patients with swallowing problems, acute myocardial infarction, atrial fibrillation/flutter, severe systolic dysfunction, mechanical valves, oral anticoagulation therapy, and/or patients with a history of stroke/systemic thromboembolic event. RESULTS: Mean patient age was 58.13 ± 12.66 years and 69.3% were men. Hypertension was encountered in 51% of our patients, 56% of them had a history of coronary artery disease, 30% had diabetes, 25% had dyslipidemia, 30% were smokers, whereas 10% were alcoholics. Mean LA dimensions resulted higher than reference values, whereas 86% of our patients had LAA dysfunction. Male gender was an independent predictor for LA diameter dilation (95% confidence interval [CI]: 1.765-9.078, P = 0.005), while lower body weight was a predictor for enlargement of LA area (95% CI: 0.044-0.351, P = 0.014) and LA volume (95% CI: 0.160-2.067, P = 0.024). CONCLUSION: Male patients with dilated cardiomyopathy at sinus rhythm with lower body weight tend to have larger LA and consequently might be at higher risk of developing atrial thrombus and its subsequent consequences.

PERICARDIAL FEATURES OF IN-HOSPITAL RHEUMATOLOGY PATIENTS: AN OBSERVATIONAL STUDY.

Rheumatic disorders can be associated with pericarditis, but severe forms of pericarditis are rare. The aim of this observational study was to evaluate pericardial features in patients with different rheumatic diseases. Thirty-five patients hospitalized at the Clinic of Rheumatology, University Clinical Center of Kosovo, from October 1 to October 21, 2014 were included in the study. Demographic data, history, laboratory, ECG, and echocardiography data, with special emphasis on the analysis of the pericardium, were obtained from each patient. Echocardiography was especially focused on the amount of pericardial fluid and pericardial thickness in the posterior wall of the heart. Mean patient age was 51.5 ± 13.8 years. 65.7% of the patients were women. Out of the patients that we analyzed, 88.6% had an inflammatory rheumatologic disease. 11.3% of the patients had mild symptoms, in 68.7% the symptoms were moderate, and in 20% severe. In all patients, pericardial hyperechogenicity was marked, with a mean pericardial thickness of 4.68 ± 1.66 mm. Pericardial effusion in a small amount was present in 57.1% of patients, with a mean pericardial fluid amount of 3.3 ± 1.9 mm. The severity of rheumatic disease had a positive and significant correlation with the presence of pericardial effusion (r= 0.29, p=0.04) and its amount (r= 0.28, p=0.05). The patients had not been aware of the pericardial involvement and did not have any clinical symptoms. In conclusion, in this short-term small observational study pericardial changes were a frequent finding in the rheumatology patients. In general, the pericarditis was subclinical and with small amounts of effusion. The disease activity of rheumatic disorders can be associated with pericarditis. Further studies with larger samples of patients and of longer duration are needed to further explore this issue.

Anomalous Origin of Left Circumflex Artery.

INTRODUCTION: The coronary anatomic variation of the left circumflex artery (LCx) is considered as the most common anatomic variation with a separate ostium from the right sinus, and very unusual variation as a proximal branch of right coronary artery (RCA). CASE REPORT: We report two cases, the first case is a 64-year-old man with chest pain and with history of hypertension, obesity, dyslipidemia and current smoker, and the second case is a 67-year-old who presented to the emergency department with chest pain and with a past medical history of arterial hypertension and type 2 diabetes mellitus. In the coronarography of the first case is detected an ectopic left circumflex coronary artery from the right coronary sinus with stenotic changes in RCA and LCx. The second case in the coronary angiography revealed an ectopic left circumflex coronary artery from the proximal part of the right coronary artery with stenotic changes in LAD, RCA and LCx. Based on guidelines for revascularization our patients successfully underwent treatment procedures. We present two cases that because of the atherosclerotic coronary artery disease leads to the need of coronarography find out the presence of coronary artery anomalies. CONCLUSION: During the coronarography we should think about coronary artery anomaly or missing artery knowing that type of these anomalies, considering that may be a contributing factor in the development of the atherosclerosis determines the method of the treatment.

Prevalence of left chamber cardiac thrombi in patients with dilated left ventricle at sinus rhythm: the role of transesophageal echocardiography.

BACKGROUND: Left atrial appendage (LAA) may be a source of thrombi in patients with dilated cardiomyopathy at sinus rhythm. The objectives of our study were to assess the prevalence of intracardiac left chamber thrombus and/or spontaneous echo contrast and to identify clinical and echocardiographic predictors for left ventricle (LV), left atrium (LA), and/or LAA thrombus formation, particularly as regard to LV, LA, and LAA size, in heart failure patients at sinus rhythm. METHODS: We included 45 patients with dilated cardiomyopathy of ischemic or idiopathic origin with mild to moderate systolic dysfunction, who were at sinus rhythm and without anticoagulation therapy. RESULTS: Mean left ventricular end diastolic diameter was 64.9 ± 6.1 mm, and mean LV ejection fraction was 39.9 ± 7.3%. LV thrombus was found in 13.3% of patients and LAA thrombus in 68. 9%. Left ventricular end diastolic diameter was correlated with LA volume (r = 0.59, p < 0.0001) and LV thrombus (r = 0.38, p = 0.005). LA volume was correlated with LAA maximal area (r = 0.34, p = 0.01), which was an independent predictor for LAA thrombus formation (p = 0.003). CONCLUSIONS: Dilation of left cardiac chambers offers a suitable terrain for thrombus formation. The high probability of LAA thrombosis should be kept in mind when designing the treatment strategy for patients with dilated cardiomyopathy at sinus rhythm.

Atrioventricular septal defect with common atrioventricular junction guarded by a common valve consisting of left atrioventricular trifoliate valve.

INTRODUCTION: Atrioventricular septal defect with common atrioventricular junction is a rare adult congenital cardiac syndrome. This occurrence with prolonged survival is exceptionally rare. CASE REPORT: We present the case of a patient who presented with this defect with common atrioventricular junction who survived to the age of 32. We describe a 32-year-old man with atrioventricular septal defect with common atrioventricular junction guarded by a common valve. His history, clinical course, and anatomic findings are discussed along with the factors which may have contributed to his longevity, which is unique in the medical literature. His management reflected the state of medical knowledge at the time when he presented, and although alternate approaches may have been utilized if the patient presented today. We discuss the findings, frequency, classifi cation, and management of congenital defects. Development of embryonic structure is altered by interaction between genetics and environmental factors toward a rare associated of congenital cardiac defects-complex congenital heart disease. CONCLUSION: This case demonstrates that patients with very complex congenital cardiac disease may survive to adulthood, presenting challenges in both medical and surgical treatment.

Left ventricular and left atrial thrombi in sinus rhythm patients with dilated ischemic cardiomyopathy.

INTRODUCTION: Ischemic dilated cardiomyopathy offers a favorable terrain for left ventricular (LV) thrombus formation; however, left artial appendage (LAA) may be an additional source of thrombi in patients with dilated heart. The main objectives of this study were to determine the prevalence of LV and LAA thrombi in patients with chronic ischemic dilated cardiomyopathy in sinus rhythm, as well as to reveal echocardiographic predictors for thrombus formation. METHODS: The study included 57 patients with chronic dilated ischemic cardiomyopathy in sinus rhythm, who were not under oral anticoagulation therapy. Exclusion criteria included patients with: swallowing problems, acute myocardial infarction, idiopathic and/or non-ischemic dilated cardiomyopathy, atrial fibrillation/flatter, severe systolic dysfunction. Transthoracic echocardiography and transesophageal echocardiography were obtained for each patient. RESULTS: Mean patient age was 62 +/- 10.5 years, mean LV end diastolic diameter was 67.2 +/- 5.8 mm, whereas mean LV ejection fraction (EF) was 37.1 +/- 4.3%. LV thrombus was detected in 11 (19.3%) patients; while 23 (40.3%) patients had LAA thrombus. In a multiple regression analysis LV size (p = 0.05) and lack of aspirin therapy (p = 0.02) showed to be independent LV thrombus predictors, whereas lower LV EF (p = 0.02) and larger LAA maximal area (p = 0.004) demonstrated to be independent predictors of LAA thrombus. CONCLUSIONS: We consider that our study sheds light to the high possibility of LAA thrombi formation in addition to LV thrombi in patients with chronic dilated ischemic cardiomyopathy in sinus rhythm. LV size, LV EF, LAA maximal area and lack of aspirin therapy are shown to be independent predictors of left heart chamber thrombi in this patient category.

Relationship of left ventricular size to left atrial and left atrial appendage size in sinus rhythm patients with dilated cardiomyopathy.

INTRODUCTION: Thromboembolic events are a frequent cause of mortality in patients with congestive heart failure. The aim of or study was to evaluate the relationship of left ventricular end diastolic diameter (LVEDD) to left atrial (LA) size and left atrial appendage (LAA) size in patients with dilated cardiomyopathy in sinus rhythm, as well as to determine the prevalence of thrombi in LV and LA /LAA. METHODS: This was a prospective cross-sectional study, conducted from December 2009 until December 2011. The study included 95 patients with dilated cardiomyopathy in sinus rhythm. Patients with swallowing problems, acute myocardial infarction, atrial fibrillation/flatter, severe systolic dysfunction, and/or patients who were taking oral anticoagulation therapy were excluded. RESULTS: Mean patient age was 58.6 ± 12.2 years and 68.4% were men. Mean LVEDD of our population was 66.5 ± 6.5 mm, while mean LA atrium, LA volume and LAA maximal area were 46 ± 5.1 mm, 87.2 ± 38.7 cm(3) and 4.7 ± 1.2 cm(2), respectively. LA diameter (p<0.001) and LAA maximal area (p=0.01) showed to be independent predictors of LV size. LV thrombus was detected in 13 (13.7%) patients, while LAA thrombus in 46 (48.4%) patients of our study population. CONCLUSIONS: In conclusion, dilated LV size is associated with enlarged LA and LAA size. On the other hand, dilation of LV, LA and LAA is related to high prevalence of left chamber cardiac thrombi.

Right bundle branch block as a marker for interatrial septal abnormalities.

BACKGROUND: Interatrial septal anomalies, which include atrial septal defect, patent foramen ovale, and atrial septal aneurysm, are common disorders among adult patients. Early detection of interatrial septal anomalies is important in order to prevent haemodynamic consequences and/or thromboembolic events. Electrocardiogram offers some clues that should serve as hints for detection of interatrial abnormalities. The aim of our study was to analyse the interatrial septum by transoesophageal echocardiography in patients with electrocardiogram signs of right bundle branch block and in those without right bundle branch block. METHODS AND RESULTS: In a prospective study, 87 adult patients were included, that is, 41 with electrocardiogram signs of right bundle branch block forming the first group and 46 without right bundle branch block forming the second group. Interatrial septal anomalies were present in 80.5% of the patients with right bundle branch block, with patent foramen ovale (39.02%) being the most prevalent disorder, followed by atrial septal aneurysm (21.9%) and atrial septal defect (19.5%). Interatrial septal abnormalities were significantly more frequent in the first group compared with the second group (80.5% versus 6.5%, p value less than 0.001). Independently, patent foramen ovale was significantly more prevalent in patients with right bundle branch block (39.02% versus 4.3%, p value less than 0.001), as were atrial septal aneurysm (21.9% versus 2.2%, p value equal 0.01) and atrial septal defect (19.5% versus 0%, p value equal 0.004). CONCLUSIONS: Right bundle branch block should serve as a valuable indicator to motivate a detailed search for interatrial septal abnormalities.

Association of interatrial septal abnormalities with cardiac impulse conduction disorders in adult patients: experience from a tertiary center in Kosovo.

INTERATRIAL SEPTAL DISORDERS, WHICH INCLUDE: atrial septal defect, patent foramen ovale and atrial septal aneurysm, are frequent congenital anomalies found in adult patients. Early detection of these anomalies is important to prevent their hemodynamic and/or thromboembolic consequences. The aims of this study were: to assess the association between impulse conduction disorders and anomalies of interatrial septum; to determine the prevalence of different types of interatrial septum abnormalities; to assess anatomic, hemodynamic, and clinical consequences of interatrial septal pathologies. Fifty-three adult patients with impulse conduction disorders and patients without ECG changes but with signs of interatrial septal abnormalities, who were referred to our center for echocardiography, were included in a prospective transesophageal echocardiography study. Interatrial septal anomalies were detected in around 85% of the examined patients. Patent foramen ovale was encountered in 32% of the patients, and in combination with atrial septal aneurysm in an additional 11.3% of cases. Atrial septal aneurysm and atrial septal defect were diagnosed with equal frequency in 20.7% of our study population. Impulse conduction disorders were significantly more suggestive of interatrial septal anomalies than clinical signs and symptoms observed in our patients (84.91% vs 30.19%, P=0.002). Right bundle branch block was the most frequent impulse conduction disorder, found in 41 (77.36%) cases. We conclude that interatrial septal anomalies are highly associated with impulse conduction disorders, particularly with right bundle branch block. Impulse conduction disorders are more indicative of interatrial septal abnormalities in earlier stages than can be understood from the patient's clinical condition.

The impact of acute myocardial infarction on left ventricular systolic function.

BACKGROUND: During acute myocardial infarction left ventricular systolic function is an important prognostic factor whose worsening is still frequent despite the therapeutic approach. We aimed to estimate the incidence of left ventricular systolic dysfunction among patients experiencing acute myocardial infarction. METHODS: The study involved 154 consecutive patients admitted at Coronary Care Unit. The study design was based upon the collection of patient histories, clinical examination and other complementary tests. RESULTS: In overall study population, predominantly with male gender, the incidence of left ventricle systolic dysfunction was 42.3%, which correlated with myocardial damage, electrocardiography changes, myocardial enzymes, and myocardial wall motion. CONCLUSIONS: Transthoracic Echocardiography represents a valuable tool and left ventricular ejection fraction should be evaluated in all patients experiencing acute myocardial infarction since the incidence of left ventricular dysfunction in patients with Acute Myocardial Infarction remains relatively high.

Limitations of CHADS2 scoring system in predicting stroke risk--need to change the age criteria.

INTRODUCTION: Atrial fibrillation (AF) is the most common arrhythmia with a strong association with age. The aim of this study was to evaluate the rate of stroke in relation to age and anticoagulation status based on CHADS2 risk criteria. METHODS: This study included all patients with non-valvular atrial fibrillation admitted to our clinic between 1/11/2007 and 1/11/2009, with minimum one year follow up for patients without stroke. We calculated risk based on CHADS2 (C-cardiac failure, H- hypertension, A-age >75 years, D-diabetes mellitus, S-stroke) point system and evaluated anticoagulation status at the moment of first occurrence of stroke. We observed the rate of stroke in different group age. RESULTS: The average of participants with AF was 67.9 +/- 10.3 years. Amongst 302 patients with non-valvular atrial fibrillation, 32.5% had been anticoagulated while 13.9% of experienced stroke. The stroke were more present in patients who used aspirin in age group 65-74 (22.5%, P = 0.014). The mean age of patients who experienced stroke were 67.2, SD +/- 10.8 vs. 71.6, SD +/- 5.1, P = 0.000. Of the patients with stroke from age group 65-74 years, 23 were in CHADS2 0-1 scoring system. CONCLUSION: The higher rate of stroke was in the 65-74 years age group, with CHADS2 scoring system 0-1, and without anticoagulation therapy. Therefore modification has to be considered for the CHADS2 scoring system to account the age as a risk factor for population in different regions.

Relationship of hypertensive retinopathy to thoracic aortic atherosclerosis in patients with severe arterial hypertension.

Arterial hypertension complicated with atherosclerosis presents the most common cause of death in hypertensive patients. Eyes suffer vascular damage as a result of high blood pressure (BP) and these changes can be detected by funduscopy, although its role has recently been questioned. The aims of this study were to assess the prevalence of atherosclerotic plaques and other disorders of thoracic aorta by transesophageal echocardiography (TEE) in patients with severe arterial hypertension of at least 1 year duration and to analyze the association between aortic atherosclerotic plaques and hypertensive retinopathy. This was a prospective TEE study conducted on 56 hypertensive patients from September 2008 to January 2010. Mean patient age was 62.8 ± 8.2 years and 67.86% of them were women. Aortic atherosclerotic plaques were found on 96.4% of patients, whereas hypertensive retinopathy was present on 94.6% of them. The mean thickness of maximal atherosclerotic plaque found on each patient was 4.3 ± 1.9 mm and 28.6% of patients had ulcerative plaques, while descending aorta was the most common location of the lesions. Grade 1 and 2 hypertensive retinopathy was diagnosed in 14.3% and 80.3% of patients, respectively. Hypertensive retinopathy correlated highly with aortic atherosclerotic score (r = 0.76, p < 0.0001), as it correlated significantly with aortic plaque thickness (r = 0.69, p < 0.0001). Application of funduscopy should be encouraged since it is a noninvasive procedure that provides a good window of retinal arterioles. Hypertensive retinopathy, even in mild forms, should serve as a marker of atherosclerosis elsewhere in the organism.
