- Abstract
Background: The main aim of this study was to detect the possible early effect of cardiac rehabilitation (CR) on left atrium (LA) and left ventricle (LV) function and relation to aortic stiffness in patients with acute myocardial infarction (AMI)., Methods: Fifty-four patients with AMI were enrolled in this study. Left atrial strain analysis was performed by two-dimensional speckle tracking echocardiography. The deceleration time (DT) was measured by pulsed-wave Doppler. The ratio of E/e' to LA peak strain was used to estimate the LA stiffness (Stiffnessstrain ) Aortic elasticity parameters were calculated using the formulas including aortic systolic and diastolic diameter with M-Mode echocardiography and blood pressure. Anterior wall aortic expansion velocity was measured by tissue Doppler imaging., Results: Left ventricle ejection fraction (EF) and LA functional parameters were significantly better in trained subjects. Also in training group, the LV diastolic functional parameters were better in CR group than the control group. Aortic elasticity parameters were better with CR., Conclusions: In patients with CR, an increase in LA strain was correlated with increase in aortic strain and improved aortic distensibility, likely indicating favorable LA and aortic interactions with exercise training., (© 2014, Wiley Periodicals, Inc.)

- Abstract
Introduction: P wave axis is one of the most practical clinical tool for evaluation of cardiovascular disease. The aim of our study was to evaluate the P wave axis in electrocardiogram (ECG), left atrial function and association between the disease activity score in patients with systemic lupus erythematosus (SLE)., Methods: Standard 12-lead surface ECGs were recorded by at a paper speed of 25 m/s and an amplifier gain of 10 mm/mV. The heart rate (HR), the duration of PR, QRS, QTd (dispersion), the axis of P wave were measured by ECG machine automatically., Results: The P wave axis was significantly increased in patients with SLE (49 ± 20 vs. 40 ± 18, P = 0.037) and the disease activity score was found positively correlated with P wave axis (r: 0.382, P = 0.011). The LA volume and the peak systolic strain of the left atrium (LA) were statistically different between the groups (P = 0.024 and P = 0.000). The parameters of the diastolic function; E/A and E/e' were better in the control group than the patients with SLE (1.1 ± 0.3 vs. 1.3 ± 0.3, P = 0.041 and 6.6 ± 2.8 vs. 5.4 ± 1.4, P = 0.036, respectively)., Conclusion: P wave axis was found significantly increased in patients with SLE and positively correlated with SELENA-SLEDAI score. As the risk score increases in patients with SLE, P wave axis changes which may predict the risk of all-cause and cardiovascular mortality.

- Abstract
In patients with mammary-coronary bypass grafts, the presence of a subclavian artery stenosis proximal to the internal mammary artery may result in a condition termed coronary-subclavian steal syndrome of which the incidence varies between 0.07-3.4% among those requiring coronary grafts. We reported a patient with a history of the coronary artery bypass graft who presented with typical angina pectoris at rest that was exacerbated by selective exercise of the left upper extremity in whom occlusion of the left subclavian artery was demonstrated in this patient by 3D reconstruction of computed tomography angiography, a reversal blood flow in the left internal mammary artery-left anterior descending artery graft by Doppler ultrasonography, and a coronary angiography.

- Abstract
Objectives: We aimed to observe the effect of cardiac rehabilitation (CR) on left ventricular diastolic function in patients with acute myocardial infarction (AMI) and revascularization by percutaneous coronary intervention (PCI)., Study Design: 82 patients were enrolled the study; 42 who were participating in a CR program, and 40 who did not maintain the program as a control group. Measurements of mitral inflow included the peak early filling (E-wave) and late diastolic filling (A-wave) velocities, the E/A ratio, deceleration time (DT) of early filling velocity and mitral A-wave duration. The early diastolic annular velocity has been expressed as e' with PW tissue Doppler imaging. The mitral inflow E velocity to tissue Doppler e' (E/e') was calculated and isovolumic relaxation time (IVRT) was measured. Measurements of pulmonary venous waveforms included peak systolic (S) velocity, peak anterograde diastolic (D) velocity and the time difference between the duration of the atrial reversal (Ar) and mitral A-wave duration (Ar-A)., Results: E/A and septal e' were better with the CR group than the control group. (p=0.048 vs p=0.006 respectively). The difference between E/e' measurements were not statistically significant (p=0.138). The left ventricular diastolic function of patients were partially improved with cardiac rehabilitation. There was no association between infarct-related artery (IRA) and diastolic functional measurements of the left ventricle in the individuals. Only hypertension was found significantly associated with E/A (p=0.000)., Conclusion: CR improves septal e' and E/A significantly in patients with AMI and revascularized successfully by PCI, especially in those with hypertension.

- Abstract
Objectives: The aim of this study was to assess whether NLR levels are associated with echocardiographic parameters, New York Heart Association (NYHA) functional class, or B- type natriuretic peptide (BNP) levels in patients with idiopathic dilated cardiomyopathy (DCM)., Design: Eighty-seven patients with idiopathic DCM were included prospectively from 2009 to 2014. Patients with acute decompensated heart failure and conditions that alter the total or differential white blood cell counts were excluded. Blood samples were collected before echocardiographic investigation on admission., Results: There was a statistically significant correlation between neutrophil/lymphocyte ratio (NLR) and NYHA functional class (r = 0.68, p < 0.001), BNP levels (r = 0.61, p < 0.001) and various echocardiographic parameters. NLR was significantly higher in patients in NYHA functional class III or IV (n = 39) than among those categorized as NYHA class I or II (n = 48), (3.3 ± 1.0 vs 2.1 ± 0.6; p < 0.001). The NLR cutoff value predicting severe chronic HF was 2.25 with 82% sensitivity and 65% specificity (p < 0.001). On multivariate linear regression analysis NLR (p = 0.025), left ventricular end-diastolic volume (p = 0.041) and left atrial volume index (LAVI) (p = 0.001) were found to be independent positive predictors of BNP levels., Conclusion: Neutrophil/Lymphocyte ratio is associated with the severity of chronic heart failure in patients with idiopathic DCM.

- Abstract
Background: The aim of our study was to investigate the P-wave dispersion from standard electrocardiograms (ECGs) in patients with acute myocardial infarction (AMI) after cardiac rehabilitation (CR) and determine its relation to arterial stiffness., Methods: This is a prospective study included 33 patients with AMI and successfully re-vascularized by percutaneous coronary intervention (PCI) underwent CR. Left ventricular ejection fraction (LVEF) was measured by biplane Simpson's method. Left atrium (LA) volume was calculated. The maximum and minimum durations of P-waves (Pmax and Pmin, respectively) were detected, and the difference between Pmax and Pmin was defined as P-wave dispersion (Pd = Pmax-Pmin). Aortic elasticity parameters were measured., Results: LVEF was better after CR. The systolic and diastolic blood pressures decreased after CR, these differences were statistically significant. With exercise training, LA volume decreased significantly. Pmax and Pd values were significantly shorter after the CR program. The maximum and minimum P-waves and P-wave dispersion after CR were 97 ± 6 ms, 53 ± 5 ms, and 44 ± 5 ms, respectively. Aortic strain and distensibility increased and aortic stiffness index was decreased significantly. Aortic stiffness index was 0.4 ± 0.2 versus 0.3 ± 0.2, P = 0.001. Aortic stiffness and left atrial volume showed a moderate positive correlation with P-wave dispersion (r = 0.52, P = 0.005; r = 0.64, P < 0.001, respectively)., Conclusion: This study showed decreased arterial stiffness indexes in AMI patient's participated CR, with a significant relationship between the electromechanical properties of the LA that may raise a question of the preventive effect of CR from atrial fibrillation and stroke in patients with acute myocardial infarction.

- Abstract
Coronary thromboembolism is a rare cause of acute coronary syndromes (ACS). The information regarding ACS in patients with prosthetic heart valves is scarce and based mainly on case reports. Although plaque rupture is the most common cause of acute myocardial infarction, coronary embolism (CE) is not a rare cause of acute myocardial infarction. There is no consensus regarding the treatment in such a situation. We present three cases of prosthetic valve thrombosis complicated with CE causing non-ST elevation ACS, who were successfully treated with thrombolytic therapy (TT). We administered low-dose (25 mg), slow-infusion (6 hours) tissue plasminogen activator (t-PA), which was shown to be safe and effective in our group in a large study. The patients benefited from TT with respect to the coronary flow, as shown by the lysis of thrombi in all three patients on coronary angiogram.

- Abstract
An effective anticoagulation is critical in pregnant patients with prosthetic heart valves. Inherited disorders may interfere with the coagulation cascade and may be associated with obstetrical complications as well as with prosthetic valve-derived complications. The patient in the present case had a history of recurrent prosthetic heart valve thrombosis (PHVT) despite an effective anticoagulation. She underwent a thrombolysis with low-dose prolonged infusion of tissue-type plasminogen activator for the management of her recurrrent prosthetic valve thrombosis. The genetic testing showed homozygous mutations of methylenetetrahydrofolate reductase (MTHFR) A 1298 C and heterozygous mutations of β-fibrinogen 455 G-A. Inherited disorders such as MTHFR A 1298 C and fibrinogen 455G/A polymorphisms may be involved in the pathogenesis of recurrent PHVT and/or pregnancy loss.

- Abstract
Infarction of the kidney is an uncommon condition that can result from obstruction or decrease of renal arterial flow. The diagnosis is often delayed because it can mimic many other pathologic states, including pyelonephritis, renal colic, acute abdomen, pancreatitis and more. A high index of suspicion is important for prompt diagnosis. We describe a 20-year-old man presented with abdominal and right flank pain and hematuria. A computed tomography scan with intravenous contrast showed partial infarction of right renal parenchyma and selective renal angiography showed complete occlusion of the right renal artery which was also supplied by an accessory renal artery. Electrocardiography showed normal sinus rhythm. Transthoracic and transesophageal echocardiographic findings were unremarkable except for mild spontaneous echo contrast (SEC) in the left atrial appendage. Subsequent 48-hour holter monitor revealed frequent premature atrial complexes and paroxysmal atrial fibrillation (PAF). Development of thromboembolic renal infarction was attributed to the presence of PAF and concurrent SEC in the left atrial appendage (LAA). Low molecular weight heparin(LMWH) was followed by oral anticoagulant and an electrophysiologic study was planned for the management of PAF after 4 weeks of anticoagulation.

- Abstract
Eustachian valve (EV) is a vestige of the valve of the inferior vena cava which directs the umbilical vein blood through open foramen ovale in fetal life. Following birth it gradually regresses, but it may persist in variable size, shape, and thickness as a functionless and benign structure. However, there are reports suggesting that persistent EV may not be completely innocent. It has been accused of being a predisposing cause of patent foramen ovale and paradoxical embolism and also interfering with transseptal interventional procedures. It may serve as a site of infective vegetations and be mistaken as a tumor or thrombus. In the present case, an octopus-like thrombus attached to the EV was delineated with the utility of two-dimensional and real time three-dimensional transesophageal echocardiography. EV was considered to play an essential role in preventing potential pulmonary embolism., (© 2013, Wiley Periodicals, Inc.)

- Abstract
Prosthetic valve thrombosis (PVT) is a life-threatening complication. Neutrophil/lymphocyte ratio (NLR) and platelet/lymphocyte ratio (PLR) have been studied as inflammatory biomarkers in atherosclerosis, but data regarding valvular disease are lacking. The study population included patients with mitral PVT (n = 152) versus control subjects (n = 164) with functional mitral prosthesis. Transesophageal echocardiography was performed to diagnose PVT. NLR and PLR were calculated using complete blood count. C-reactive protein (CRP) levels were also analyzed. Neutrophil and platelet levels did not differ between the groups (4.9 ± 2.0 vs 4.7 ± 1.5, p = 0.84 and 254.8 ± 89.7 vs 241.5 ± 62.8 p = 0.36, respectively), but lymphocyte levels were significantly lower in patients with PVT than the controls (1.8 ± 0.7 vs 2.2 ± 0.6, p <0.001). NLR, PLR, and CRP levels were significantly higher in patients with PVT than in controls (3.2 ± 2.1 vs 2.2 ± 0.8, p <0.001; 163 ± 77.5 vs 114.9 ± 37.3, p <0.001; and 1.97 ± 3.02 vs 1.02 ± 1.22, p = 0.01, respectively). A positive correlation was observed between NLR and PLR (r = 528, p <0.001). NLR level of >2.23, measured on admission, yielded an area under the curve value of 0.659 (95% confidence interval 0.582 to 0.736, sensitivity 66%, specificity 60%, p <0.001) and PLR level of >117.78 yielded an area under the curve value of 0.707 (95% confidence interval 0.636 to 0.777, sensitivity 70%, specificity 58%, p <0.001). Multivariate analysis showed that increased PLR and inadequate anticoagulation were independent predictors of thrombosis in patients with PVT. In conclusion, patients with PVT had increased NLR, PLR, and CRP levels compared with subjects with normofunctional prosthesis, and increased PLR was an independent predictor of mitral PVT., (Copyright © 2014 Elsevier Inc.
