ABSTRACT
BACKGROUND: Relation of plasma fibrinogen levels with extent, severity, and complexity of coronary artery disease (CAD) in patients with stable angina pectoris (SAP) has not been adequately investigated. The aim of this study was to evaluate whether plasma fibrinogen level is associated with coronary complexity, severity, and extent assessed by SYNTAX (Synergy between percutaneous coronary intervention with TAXUS and Cardiac Surgery) score (SS). METHODS: We enrolled 134 consecutive patients with SAP who underwent coronary angiography. Baseline serum fibrinogen levels were measured, and SS was calculated from the study population. The patients were classified into 3 groups by tertiles of SS (SS, control group = 0; intermediate group < 22; and high group ≥ 22). RESULTS: Plasma fibrinogen levels demonstrated a stepwise increase from control group to high SS group. There was a strong correlation between fibrinogen and the SS ( r = .535, P < .001). Area under the receivers operating characteristic curve of fibrinogen was 0.72 (95% confidence interval [CI] 0.61-0.82; < .001) for predicting a high SS. Fibrinogen value higher than 411 mg/dL has a sensitivity of 75% and a specificity of 64% in prediction of high SS. In multivariate analyses, plasma fibrinogen was observed to be an independent predictor for high SS in patients with stable CAD (odds ratio [OR] 1.01; 95% CI, 1.01-1.02; P < .001). CONCLUSION: Plasma fibrinogen is a readily measurable systemic inflammatory marker and is independently associated coronary severity and complexity in patients with CAD.

BACKGROUND AND OBJECTIVES: The aim of this study was to evaluate the association between the extent of coronary artery disease assessed by the Gensini score and/or the SYNTAX score and the significant carotid stenosis in patients undergoing coronary artery bypass grafting (CABG). SUBJECTS AND METHODS: A total of 225 patients who had carotid doppler ultrasonography prior to CABG were included retrospectively. Significant coronary artery disease was assumed as a lumen diameter stenosis of ≥50% in any of the major epicardial coronary arteries. The severity of carotid stenosis was determined by B-mode and duplex ultrasonography. Clinically significant carotid stenosis was defined as peak systolic velocity greater than 125 cm/s. RESULTS: The mean value of SYNTAX score and Gensini score was highest in patients allocated to significant carotid stenosis (22.98±7.32, p<0.001 and 77.40±32.35, p<0.001, respectively). The other risk factors for significant carotid stenosis were found to be male gender (p=0.029), carotid bruit (p<0.001), diabetes (p=0.021), left main disease (p=0.002), 3-vessel disease (p=0.008), chronic total coronary occlusion (p=0.001), and coronary artery calcification (p=0.001) in univariate analysis. However, only the Gensini score (odds ratio[OR]=1.030, p=0.004), carotid bruit (OR=0.068, p<0.001), and male gender (OR=0.190, p=0.003) were the independent predictors. The Gensini score cut off value predicting significant carotid stenosis was 50.5 with 77% sensitivity (p<0.001). CONCLUSION: The Gensini score may be used to identify patients at high risk for significant carotid stenosis prior to CABG.
ABSTRACT
BACKGROUND: Arrhythmogenic right ventricular dysplasia (ARVD) is characterized by the progressive replacement of ventricular myocytes with variable amounts of fibrous and adipose tissue. Several studies have suggested that speckle tracking echocardiographic (STE) parameters such as strain (S) and strain rate (SR) may prove useful in the early detection of right ventricular (RV) dysfunction. Therefore, the aim of this study was to evaluate RV myocardial function using the STE method in both asymptomatic and symptomatic patients with ARVD and to assess its potential role in the differential diagnosis of these two presentations. METHODS: We recruited 34 patients with ARVD. Seventeen patients were symptomatic, and seventeen were asymptomatic. RESULTS: The RV free wall global longitudinal S and SR were significantly lower in symptomatic patients with ARVD than in asymptomatic patients. According to a cutoff value of 1.35 per seconds for RV global SR, the sensitivity and specificity for predicting ARVD were 88% and 77%, respectively. According to a cutoff value of 17.3% for RV S, the sensitivity and specificity for predicting ARVD were 82% and 77%, respectively. CONCLUSION: In conclusion, we present strong evidence that STE-derived global S and SR in the RV free wall are decreased in symptomatic patients with ARVD compared with asymptomatic patients.

The fastest growing demographic group in Europe and America is the elderly, and significant mitral regurgitation is very prevalent in this population. At present, with mitral valve surgery in elderly individuals gaining greater acceptance worldwide, the question whether to repair or replace the valve remains controversial. Recent studies have demonstrated the safety, feasibility, and durability of repair over replacement in elderly patients. Herein, we report the case of an elderly patient who underwent surgical re-interventions on the mitral valve following an unsuccessful mitral valve repair procedure.

BACKGROUND: The goal of this study was to determine changes in left atrial (LA) function with two-dimensional speckle tracking echocardiography (2DSTE) and real-time full-volume three-dimensional echocardiography (RT3DE) after percutaneous mitral valve repair with the MitraClip system. Furthermore, we investigated whether baseline and/or changes in LA function after MitraClip repair had any impact on prognosis. METHODS: A total of 25 consecutive patients (age: 57±12 years, 76% male) with moderate-to-severe or severe mitral regurgitation (MR) were included. Patients underwent 2DSTE and RT3DE before the clip implantation and after the 12-month follow-up. Prognostic data were also recorded via the use of telephone calls and follow-up visits for 12 months after the procedure. RESULTS: Compared with the baseline, the LA reservoir strain (LA-Res) (7.66±4.3% vs 11.15±7.5%, P<.001) and LA contraction strain (LA-Pump) (4.64±4.3% vs 7.63±5.8%, P=.001) improved significantly after MitraClip repair; significant improvements were also seen in three-dimensional (3D) minimum LA volume index (LAV min) and maximum LA volume index (LAV max). On the other hand, conventional LA indices did not change. In total, eleven major adverse cardiac events (MACE) were observed at the 1-year follow-up. In univariate analyses, the preprocedural echocardiographic parameters that were associated with the MACE within 1 year after MitraClip repair were 3D-LAV min and LA-Res. Furthermore, these indices significantly correlated with improved functional parameters and MR reduction. CONCLUSION: In conclusion, a successful MitraClip procedure can reverse the process of LA remodeling within 12 months, and this can be detected by 2DSTE and RT3DE. Also, patients with preprocedural lower LA-Res and higher 3D-LAV min had the worst prognoses at the 1-year follow-up.

BACKGROUND: Right ventricular (RV) effects of long-term use of anabolic-androgenic steroids (AAS) are not clearly known. The aim of this study was to assess RV systolic functions by two-dimensional speckle tracking echocardiography (2DSTE) in AAS user and nonuser bodybuilders. METHODS: A total of 33 competitive male bodybuilders (15 AAS users, 18 AAS nonusers) were assessed. To assess RV systolic functions, all participants underwent standard two-dimensional and Doppler echocardiography, and 2DSTE. RESULTS: Interventricular septal thickness, left ventricle posterior wall thickness, relative wall thickness, and left ventricle mass index were significantly higher in AAS users than nonusers. While standard diastolic parameters were not statistically different between the groups, tissue Doppler parameters including RV E' and E'/A' were lower in AAS users than nonusers (10.1 ± 2.0 vs. 12.7 ± 2.1; P = 0.001, 1.1 ± 0.1 vs. 1.5 ± 0.4; P = 0.009, respectively). Tricuspid annular plane systolic excursion, RV fractional area change, and RV S' were in normal ranges. However, RV S' was found to be lower in users than nonusers (12.2 ± 2.2 vs. 14.6 ± 2.8, P = 0.011). RV free wall longitudinal strain and strain rate were decreased in AAS users in comparison with nonusers (-20.2 ± 3.1 vs. -23.3 ± 3.5; P = 0.012, -3.2 ± 0.1 vs. -3.4 ± 0.1; P = 0.022, respectively). In addition, there were good correlations between 2DSTE parameters and RV S', E', and E'/A'. CONCLUSION: Despite normal standard systolic echo parameters, peak systolic RV free wall strain and strain rate were reduced in AAS user bodybuilders in comparison with nonusers. Strain and strain rate by 2DSTE may be useful for early determination of subclinical RV dysfunction in AAS user bodybuilders.

OBJECTIVES: We aimed to investigate the relationship between the platelet-lymphocyte ratio (PLR) and coronary collateral circulation (CCC) in patients with stable angina pectoris (SAP) and chronic total occlusion (CTO). METHODS: A total of 294 patients with both SAP and CTO were classified according to their Rentrop collateral grades as either poor (Rentrop grades/0-1) or good (Rentrop grades/2-3). RESULTS: The PLR values were significantly higher in patients with poor CCC than in those with good CCC (156.8 + 30.7 vs 132.1 + 24.4, P < 0.001). In regression analysis, PLR (unit = 10) [odds ratio 1.48, 95% confidence interval (CI) 1.33 -1.65; P < 0.001] and high-sensitivity C-reactive protein were found to be the independent predictors of poor CCC. In receiver operator characteristic curve analysis, optimal cut-off value of PLR to predict poor CCC was found as 138.1, with 76% sensitivity and 65% specificity. CONCLUSION: PLR may be an important, simple, and cost effective tool predicting the degree of collateralization in patients with SAP and CTO.

BACKGROUND: The aim of this study was to assess whether epicardial fat thickness (EFT) is associated with the severity of heart failure in patients with nonischemic dilated cardiomyopathy (NICMP). METHODS: The study group was composed of 93 patients with NICMP and38 age- and sex-matched healty individuals as the control group. The EFT was identified during end-systole at the point on the free wall of the right ventricle. RESULTS: Patients with NICMP had significantly lower mean EFT than those in the control group (4.1 ± 0.8 vs. 6.1 ± 1.8 mm, P < 0.001). EFT was thinnest in patients with New York Heart Association (NYHA) functional class III or IV (3.5 ± 0.5, P < 0.001). There was a significant correlation between EFT, left ventricle EF (r = 0.540 P < 0.001), and B-type natriuretic peptide (BNP) (r = -0.695, P < 0.001) values in patients with NICMP. In addition, when EFT was corrected for BMI, EFT/BMI was lower in patients with NYHA functional class III-IV than patients with NYHA class I-II and control group (0.13 ± 0.01, 0.16 ± 0.02, 0.23 ± 0.04, respectively; P < 0.001). There was a significant correlation between EFT/BMI, left ventricle EF (r = 0.489, P < 0.001), and BNP (r = -0.549, P < 0.001) in patients with NICMP. In multivariate regression analysis, EFT (P = 0.009), BNP (P = 0.039), and left atrium volume index (P = 0.039) were independently associated with impaired functional status. CONCLUSION: Echocardiographic EFT is an inexpensive, simple, and readily available marker that may be used to asses the severity of chronic heart failure in patients with NICMP.

A 55-year-old man presented with the emergency department after having a short syncopal episode and angina during the exertion for 1 month. His initial electrocardiogram showed minimal ST-segment changes on precordial leads. While waiting for the laboratory tests, abruptly, the patient went into cardiopulmonary arrest. After a short resuscitation, a new electrocardiogram revealed ST-segment elevations in leads V1-3 and AVR, mimicking an anteroseptal myocardial infarction. Although, the angiography showed severe coronary artery disease, coronary flow was normal and main branches of pulmonary artery were almost fully occluded by large pulmonary emboli. Recombinant tissue plasminogen activator bolus (25 mg) was given 2 times at 5-minute intervals immediately into pulmonary artery by pig-tail catheter under the cardiopulmonary resuscitation. The patient had an excellent response to high-dose bolus thrombolytic therapy. We conclude that in the case of massive pulmonary embolism with small chance of resuscitation, the catheter-directed high-dose bolus injection of recombinant tissue plasminogen activator could enrich the therapeutical possibilities.

We investigated the effect of long-term supraphysiologic doses of anabolic androgenic steroids (AAS) on atrial electromechanical delay (AEMD) in male bodybuilders. We clearly demonstrated that long-term consumption of supraphysiologic doses of AAS is associated with higher values of inter- and intra-AEMD in healthy young bodybuilders.

ABSTRACT
Strain (S) and strain rate (SR) are known to be altered in diseases associated with right ventricular (RV) pressure/volume overload and RV myocardial dysfunction; however determinants of S/SR are incompletely understood. The aim of this study was to examine the effect of blood donation-mediated volume reduction on regional RV deformation in healthy young adults. Study population was composed of 61 consecutive healthy subjects who were volunteers for blood donation. All underwent standard echocardiography and two-dimensional S and SR imaging by speckle tracking before and after 450 mL blood donation. We found no change in RV lateral wall SR in all three segments. However, the S in the apical and mid segments of the RV lateral wall immediately decreased after blood donation [-26.2 ± 3.3 vs. -23.2 ± 3.3 % (p < 0.0001) and -28.2 ± 3.4 vs. -27.1 ± 3.2 % (p = 0.009), respectively], whereas no change was observed in the basal segment. Moreover, changes in systolic S on the apical segment of the RV lateral wall before and after blood donation were significantly correlated with the changes in the RV size [end-diastolic area index, r = - 0.369 (p = 0.003) and end-systolic area index, r = - 0.319 (p = 0.012)] and changes in the stroke volume index [r = - 0.436 (p < 0.001)]. Blood donation-mediated volume reduction in healthy subjects caused a regional difference in RV longitudinal deformation with the lower mid and apical S that was related to parameters of volume load severity. However, RV systolic SR was found to be resistant to the effects of volume depletion.

The influence of plasma adiponectin levels on myocardial contractile function has not been fully examined. We aimed to investigate the relationship between three-directional systolic function and plasma adiponectin levels in asymptomatic hypertensive patients using two- dimensional speckle-tracking echocardiography. The study population consisted of 78 patients with hypertension and 40 healthy controls. Longitudinal strain was significantly reduced in all patients, including those without LV hypertrophy (p=0.009). In multiple-regression analysis, plasma adiponectin levels (ß=-0.273, p=0.008) and LV mass index (ß=0.458, p<0.001) independently correlated with LV longitudinal strain. Decreased plasma adiponectin concentrations were associated with the progression of LV hypertrophy with impaired LV longitudinal systolic function.

We present a case of concomitant left ventricle (LV) to right atrial shunt (Gerbode-like defect) and anterior mitral leaflet perforation in a 32-year-old male after aortic valve replacement for infective endocarditis of bicuspid aortic valve. This case emphasises that intra-operative transesophageal echocardiography is a sine qua non for valvular surgical procedures.
