    ABSTRACT: BACKGROUND: There are few prospective data available for establishing a standard diuretic administration regimen for patients with acute decompensated heart failure (ADHF). We aimed to assess the safety and efficacy of three regimens of furosemide administration in patients with ADHF with regard to diuresis, renal functions, and in-hospital outcomes. METHODS: A total of 43 patients who presented with ADHF were randomized into three groups: (a) continuous infusion (cIV) of 160 mg furosemide for 16 h/day (n = 15); (b) bolus injections (bI) of 80 mg furosemide twice a day (n = 14); (c) and administration of 160 mg furosemide plus hypertonic saline solution (HSS) as an infusion for 30 min once a day (n = 14). All regimens were continued for 48 h. Study endpoints were negative fluid balance assessed by loss of body weight, change in the serum creatinine (baseline to 48 h and baseline to compensated state), and length of hospitalization. RESULTS: There was no significant difference in the mean change in serum creatinine level at the end of 48 h between groups (p = 0.08). There was also no significant difference among groups regarding loss of body weight (p = 0.66). A significantly shorter hospitalization was observed in patients treated with HSS compared with the other groups (cIV group 6.6 ± 3.4 days vs. bI group 7.9 ± 4.1 days vs. HSS group 3.7 ± 1.3 days; p < 0.01). CONCLUSION: All three furosemide regimens have similar renal safety and efficacy measures. However, administration of furosemide plus HSS may be the preferred diuretic strategy because of its shorter hospital stay.

    ABSTRACT: Our aim was to investigate body composition changes, epicardial adipose tissue thickness (EATT), serum omentin-1 levels, and the relationship among them along with some atherosclerosis markers in overt hypothyroidism. Twenty-eight newly diagnosed overt hypothyroid patients were evaluated before and after 6 months of thyroid hormone replacement therapy (THRT) and compared to the healthy subjects in this prospective longitudinal study. Body compositions were measured with dual-energy X-ray absorptiometry, and EATT was measured by echocardiography. Carotid intima-media thickness (c-IMT), flow-mediated dilatation (FMD), thyroid hormone levels, lipid parameters, high sensitive c-reactive protein, homocysteine, and omentin-1 levels were measured in all subjects. Body weight and lean body mass were higher in patients with hypothyroidism compared to euthyroid state after THRT (p = 0.012, 0.034, respectively). EATT was higher in patients with hypothyroidism than the control group (p < 0.001) and decreased with THRT (p = 0.012) but still remained higher than the control group (p < 0.001). Free T4 levels were found to be an independent factor to predict EATT (p < 0.001). In hypothyroid state, omentin-1 levels were lower than controls (p = 0.037) but increased in 6 months with THRT (p = 0.001). The c-IMT was higher, and FMD was lower in hypothyroidism compared to euthyroid state and control group (p < 0.05). Increasing lean body mass, but not adipose tissue mass, was found to be responsible for weight gain in hypothyroidism. The increased amount of EATT and decreased omentin-1 levels can contribute to the development of atherosclerosis in addition to other factors in hypothyroidism.

    ABSTRACT: Hypertension, non-dipper blood pressure (BP) pattern and decrease in daily urine output have been associated with left ventricular hypertrophy (LVH) in peritoneal dialysis (PD) patients. However, there is lack of data regarding the impact of different PD regimens on these factors. We aimed to investigate the impact of circadian rhythm of BP on LVH in end-stage renal disease patients using automated peritoneal dialysis (APD) or continuous ambulatory peritoneal dialysis (CAPD) modalities. Twenty APD (7 men, 13 women) and 28 CAPD (16 men, 12 women) patients were included into the study. 24-h ambulatory blood pressure monitoring (ABPM) and transthoracic echocardiography besides routine blood examinations were performed. Two groups were compared with each other for ABPM measurements, BP loads, dipping patterns, left ventricular mass index (LVMI) and daily urine output. Mean systolic and diastolic BP measurements, BP loads, LVMI, residual renal function (RRF) and percentage of non-dippers were found to be similar for the two groups. There were positive correlations of LVMI with BP measurements and BP loads. LVMI was found to be significantly higher in diastolic non-dippers compared to dippers (140.4 ± 35.3 vs 114.5 ± 29.7, respectively, P = 0.02). RRF and BP were found to be independent predictors of LVMI. Non-dipping BP pattern was a frequent finding among all PD patients without an inter-group difference. Additionally, higher BP measurements, decrease in daily urine output and non-dipper diastolic BP pattern were associated with LVMI. In order to avoid LVH, besides correction of anemia and volume control, circadian BP variability and diastolic dipping should also be taken into consideration in PD patients.

    ABSTRACT: Background Fragmented QRS (fQRS) is an indicator of nonhomogeneous ventricular activity caused by myocardial fibrosis. Aortic stenosis (AS) is known to be a cause of myocardial fibrosis. We aimed to investigate the relationship of fQRS with severity of AS, echocardiographic, and electrocardiographic findings, and development of atrial fibrillation and manifest heart failure in AS patients.Methods One hundred four patients with moderate and severe AS were recruited for the study. Patients with mitral or tricuspid stenosis, previous myocardial infarction, segmental wall motion abnormality or left ventricular ejection fraction (LVEF) below 50% and patients with complete-incomplete BBB and pacemaker rhythm were excluded.ResultsMean age of the patients was 69 ± 14.8 and 73.1% had fQRS. Patients with fQRS had lower LVEF, higher mean QRS duration, intrinsic deflection, Cornell voltage, Romhilt-Estes Score, systolic pulmonary artery pressure, mean and peak systolic transaortic gradients and left atrium diameter. Manifest heart failure was more frequent in patients with fQRS. In stepwise multivariate logistic regression analyze, manifest heart failure, peak systolic transaortic gradient, LVEF, intrinsic deflection, strain pattern and Cornell voltage were independently associated with fQRS. Strain pattern and fQRS were found as independent predictors of severe AS.ConclusionsfQRS is independently associated with the severity of AS while traditional LVH criteria, except strain pattern, are not. fQRS may be better than traditional ECG criteria of LVH and echocardiographic LVH as an indicator of myocardial fibrosis in AS. Thus, fQRS may have a role in determining the severity and prognosis of AS.

    ABSTRACT: Chronic volume overload, hypertension and left ventricular hypertrophy are major risk factors contributing to the high mortality rate in peritoneal dialysis (PD) patients. In this study, we aimed to determine the impact of blood pressure measurements and volume status determined by bioelectrical impedance analysis (BIA) measurements over left ventricular hypertrophy (LVH) in PD patients. Thirty-one prevalent PD patients were enrolled. Patients with a documented cardiovascular disease and uncontrolled hypertension were excluded. BIA and transthoracic echocardiography were performed in all patients All measurements were taken with the empty abdominal cavity. Routine laboratory parameters were also assessed in all patients. Extracellular water (ECW) in liters and ECW/total body water (TBW) ratio were used for determining volume status. Mean age of the patients was 43.9 ± 15.4 years, and mean PD duration was 39.5 ± 29.6 months. Mean ECW/TBW ratio was 44.3 %. Left ventricular mass index (LVMI) was 134.3 ± 34.9 g/m(2). Fifty-eight percent of patients had LVH. Mean LVMI was negatively correlated with daily urine volume (r -0.568, p 0.001) and weekly Kt/V (r -0.393, p 0.029); positively correlated with daily ultrafiltration (r +0.585, p 0.001) and office systolic (r +0.500, p 0.004) and diastolic (r +0.459, p 0.009) blood pressures. In linear regression analysis, daily urine volume (B -0.426, p 0.002) mean diastolic blood pressure (B 0.550, p <0.001), ECW/TBW ratio (B 0.313, p 0.02) and waist circumference (B 0.304, p 0.016) were independent risk factors for LVH. We want to underline that, besides maintaining residual renal function, strict blood pressure control, particularly diastolic blood pressure, and avoiding hypervolemia and abdominal obesity should be main clinical goals in follow-up of PD patients in order to prevent LVH progression.

    ABSTRACT: Introduction: The significant improvement in life expectancy resulted in an increasingly older population in almost all regions of the world, which necessitated adequate knowledge and therapeutic measures involving the problems of the elderly. Cardiovascular system as well as other organs is greatly affected by aging. Therefore, optimal cut-off values are required to distinguish physiologic changes from pathologic processes. Currently, there is not enough echocardiographic information regarding aging-associated changes in the octogenarian population. We aimed to characterize echocardiographic measures of structure and function among a group of healthy octogenarians. Material and Methods: We screened approximately 350 octogenarians, residing in nursing homes, during a 3-year period. Subjects with history of atherosclerotic heart disease, previous myocardial infarction, atrial fibrillation, hypertension, diabetes mellitus, permanent pacemaker, obesity (BMI >=30 kg/m2), known thyroid disorders, chronic systemic disorders, and current smoking were excluded. We identified 60 subjects, 20 of whom were also excluded due to moderate-severe valve disease, segmental/global kinesis abnormalities, pulmonary hypertension, and poor acoustic window. Therefore, we included 40 healthy subjects at 80 to 89 years age (mean age 83.8 ± 2.8), including 27 females (%67.5) and 13 (% 32.5) males. Healthy was defined as being able to do daily activities without any help, medication and symptoms. Our subjects had Class I functional capacity according to New York Heart Association. The subjects underwent standard echocardiographic and tissue Doppler imaging according to guidelines of the American Society of Echocardiography (ASE). All measurements were indexed by dividing to body surface area (BSA) for standardization. Results: Left ventricular mass, posterior wall thickness, right ventricular diameter, tricuspid E/A ratio and septal e’ wave velocity were significantly higher in men, which lost significance after adjusting for BSA. Moreover, mild global left and right ventricular dysfunction including a prominent diastolic counterpart however with normal ejection fraction was revealed using conventional and tissue Doppler techniques. Lastly, we checked our results with the current reference values of the ASE and observed the following differences: ventricular septum, relative wall thickness, left ventricular mass and mass index values were above ASE reference range, posterior wall measurements were close to upper range. On the contrary, left ventricular diameters and volumes were below ASE reference range (Table 1). Discussion: We examined echocardiographic measures of structure and function of the heart among a group of healthy octogenarians. Moreover, we obtained reference range, mean and 95% confidence interval values derived from conventional and tissue Doppler examination specific to this age group.

    ABSTRACT: Currently, there is not enough echocardiographic information regarding aging-associated changes in the octogenarian population. We aimed to characterize echocardiographic measures of structure and function among a group of healthy octogenarians. Approximately 350 octogenarians, residing in nursing homes, were screened in Ankara, Turkey. According to inclusion criteria, 40 octogenarians were enrolled. These subjects underwent conventional and tissue Doppler echocardiography according to the guidelines of the American Society of Echocardiography (ASE). The population was also separated into various groups according to gender, body mass index (BMI, <25 vs. 25-29.9), and blood pressure (<80/120 mmHg vs. 80-89/120-139 mmHg). All measurements were indexed by dividing to body surface area (BSA) for standardization. Left ventricular mass (LVM), posterior wall thickness, right ventricular diameter, tricuspid E/A ratio, and septal e'-wave velocity were significantly higher in men, which lost significance after adjusting for BSA. There was no significant difference between groups formed by BMI and blood pressure. Moreover, mild global left and right ventricular dysfunction including a prominent diastolic counterpart, however, with normal ejection fraction was revealed using conventional and tissue Doppler techniques. Finally, we checked our results with the current reference values of the ASE and observed the following differences: ventricular septum, relative wall thickness, LVM, and mass index values were above ASE reference range, posterior wall measurements were close to upper range. On the contrary, left ventricular diameters and volumes were below ASE reference range. We described echocardiographic measures of structure and function in a group of healthy octogenarians.

    ABSTRACT: Background: The data about cardiovascular changes in patients with asymptomatic primary hyperparathyroidism (PHPT) are scarce. Aim: The aim of this study is to compare cardiac structure and functions in patients with asymptomatic PHPT and controls by using tissue Doppler echocardiography. Subjects and Methods: Thirty-eight patients with asymptomatic PHPT and 31 sex- and age matched with similar cardiac risk factors controls were evaluated. Results: There was no significant difference in ejection fraction (EF) between the patients and the controls [64±5.95 vs. 62±3.25 %; (p=0.094)]. Left ventricular mass index (LVMI) was significantly higher in the patients than the controls [105.96 (66.45-167.24) vs. 93.79 (64.25-139.25) g/m2; p=0.014]. There was significant correlation between LVMI and serum calcium (Ca) (r=0.240, p<0.005). Myocardial performance index (MPI) was significantly higher in the patients compared to controls [0.49 (0.35-0.60) vs. 0.39 (0.33-0.62); p<0.001]. There was positive correlation between the MPI and serum Ca levels (r=0.505, p<0.001), PTH levels (r=0.464, p<0.001) and LVMI (r=0.270, p<0.005). When the normotensive patients and controls were evaluated, the difference between the groups remained statistically significance considering LVMI and MPI [109 (66.45-167.24) g/m2 vs 94.17 (64.25-75.10) g/m2 p=0.03; and 0.49 (0.35-0.60) vs 0.39 (0.33-0.62) p<0.01 respectively]. There were significant correlations between MPI and Ca (r=0.566, p<0.001), PTH (r=0.472, p<0.001). Conclusions: Our study results showed that cardiac morphology and diastolic functions are altered in the patients with asymptomatic PHPT. High serum PTH and Ca levels may have an impact on these cardiovascular changes. Whether these subtle cardiovascular changes would affect cardiac systolic functions and mortality in patients with asymptomatic PHPT should be investigated in further prospective studies.

    ABSTRACT: Many studies have shown that bilirubin may protect against atherosclerosis. In the present study, we assess the association between serum total bilirubin levels and the severity of coronary artery disease (CAD) assessed by angiography and the Syntax score. Patients from our center, who visited the center for a coronary angiography, from January 2008 to January 2011, were eligible for this analysis. Serum bilirubin levels and other blood parameters in at least 12-h fasting states were determined. The patients were divided into tertiles according to their Syntax score. A total of 299 patients were registered for the study. The total bilirubin levels in the low Syntax score group were significantly higher than those of the other groups. After multiple logistic regression analysis, serum bilirubin levels (odds ratio=0.155, 95% confidence interval, 0.039-0.62, P=0.008) were identified as independent correlates of a high Syntax score. Serum bilirubin levels were independently and inversely associated with the severity of disease in patients with stable CAD. Serum total bilirubin level may be useful as a marker of the severity of CAD.

    ABSTRACT: In this study, we aimed to evaluate the relationship between TIMI myocardial perfusion (TMP) grade, as an indicator of myocardial reperfusion, and fragmented QRS (fQRS) in standard 12-lead electrocardiogram. Also, we evaluate fQRS is an additional indicator of myocardial reperfusion. One hundred patients admitted with first STEMI to Coronary Intensive Care Unit and who were used thrombolytic therapy was included in this retrospective study. Standard 12-lead electrocardiogram records of patients simultaneous with coronary angiography (second day) were assessed and analysed for the presence of fQRS. Also, coronary angiography images were analyzed to identify the infarct related artery, TIMI grade of infarct related artery and TMP grade of infarct related artery. The patients with fQRS demonstrated a significantly lower TMP grade, TIMI grade and ejection fraction compared with the non-fQRS patients (P = 0.004, P = 0.003, P = 0.02 respectively). The patients with inadequate myocardial reperfusion demonstrated a significantly higher fQRS compared with the adequate myocardial reperfusion patients. (56.9% versus 23.5%, P = 0.002 respectively). On correlation analysis, there was a significant negative correlation between fQRS and left ventricular ejection fraction (r = -232, P = 0.02) TMP grade and adequate myocardial reperfusion (TMP 3) showed significant negative correlation with fQRS (r = -0.370, P = 0.000; r = -0.318, P = 0.001 respectively). Presence of fragmented QRS in STEMI patients was associated with inadequate myocardial reperfusion and it can be used as a simple, noninvasive parameter to evaluate myocardial reperfusion.

    ABSTRACT: In this study, we aimed to investigate endothelial functions in primary Sjögren syndrome. Thirty-five patients with primary Sjögren syndrome and 20 age and sex-matched healthy volunteers were recruited to the present study. Flow mediated dilatation of brachial artery and carotid intima-media thickness were measured in the study population. Carotid intima-media thickness values were similar between groups (0.50 +/- 0.10, 0.53 +/- 0.08, p > 0.05). Flow mediated dilatation of the brachial artery was disrupted in the primary Sjögren syndrome group (7% vs 12%, p = 0.002). There is endothelial dysfunction in patients with primary Sjögren syndrome, although they had comparable carotid intima-media thickness with the healthy control group.

    ABSTRACT: Purpose: In this study we aimed to investigate myocardial function and atrial electromechanical properties by conventional and tissue doppler echocardiography in patients with primary Sjögren syndrome. Methods: Forty patients with Sjögren syndrome (SS) and 25 age- and sex-matched healthy volunteers were enrolled in the study. Using transthoracic echocardiography, myocardial performance index and atrial electromechanical properties were measured. Results: Basal characteristics were similar between two groups. Myocardial performance index values were disturbed in patients with Sjögren syndrome (0.41 vs. 0.32, p < 0.01). There was significant intraatrial (16.4±6.4, 5.0±4.5, p < 0.01) and interatrial (30.6±10.1, 15.4±5.9, p < 0.01) electromechanical delay in this patient group. Conclusion: Myocardial function is disturbed and there is significant atrial electromechanical delay in patients with primary SS. This study is the first to show altered myocardial function and atrial electromechanical properties in primary SS.

    ABSTRACT: Background: Oxidative stress seems to play an important role in the pathophysiology of essential hypertension. We aimed to examine serum MDA, NO, 8-OHdG, ADMA, NT, CoQ10 and TAC as biomarkers of oxidative stress in dipper and non-dipper hypertensive patients. Methods: Eighteen dipper hypertensives, 20 non-dipper hypertensives and 22 healthy control subjects were included in the study. Clinical assessment and ambulatory blood pressure monitoring were performed in patients. Serum MDA, TAC and NO levels were measured by using spectrophotometric methods. CoQ10 levels were measured by HPLC method. 8-OHdG, ADMA and NT were quantitated by ELISA methods. Results: MDA levels were significantly higher in dipper and non-dipper groups compared to controls (p<0.05 and p<0.01, respectively). TAC levels were found at low level in patients dipper and non-dipper patients compared to control group (p<0.01). Higher ADMA and NT levels but lower CoQ10 levels were found in non-dipper group compared to healthy controls (p<0.01, p<0.05, and p<0.05, respectively). ADMA levels were found higher in non-dipper group than those of dipper group (p<0.01). Discussion: Increased ADMA, NT levels and decreased CoQ10 levels in non-dipper hypertensive patients might indicate more severe oxidative stres compared with dipper hypertensive patients, which plays an important role in the development of cardiovascular diseases. Increased MDA and reduced TAC levels might be considered as prospective prognostic markers of the development of cardiovascular diseases in dipper and non-dipper hypertensive patients.

    ABSTRACT: Three factor VII (FVII) promoter haplotypes are associated with stratified plasma FVII levels. To our knowledge, this is the first study examining the distribution of FVII gene polymorphism and levels in Turkish population. The study population was classified into 3 groups according to the absence of coronary arterial disease and presence or absence of a history of myocardial infarction. It was found that the levels of FVII coagulant activity (FVIIc) were higher in the event group than that of the other groups. Participants with high FVIIc levels were found to have 2-fold increased risk for myocardial infarction. The alleles at the FVII loci in all cases are similar. In conclusion, our results indicate that FVIIc levels have an important predictive role in cardiovascular events. The distribution of FVII gene polymorphisms in the Turkish population shows significant differences when compared with European populations.

    ABSTRACT: The purpose of this study was to evaluate whether a association exits among overweight and obesity and left ventricular systolic and diastolic functions in patients admitted with first ST-elevation myocardial infarction (STEMI). The present study was performed on 451 consecutive patients diagnosed with first STEMI (376 men, 75 women; mean age 56.1 ± 10.8 years). The patients were classified into three groups based on their body mass index (BMI) as normal weight (BMI < 25 kg/m2), overweight (BMI: 25-29.9 kg/m2) and obese (BMI > 30 kg/m2). Echocardiographic features were evaluated and compared among the three groups. Mitral annulus E velocities were higher in obese individuals than normal weight group (p < 0.01). In contrast, mitral A velocities were lower (p =0.03); consequently, E\A and E'\A' ratios were lower (both p = 0.01) in the obese group with respect to normal weight group. When the correction of entire variations existing among the groups were performed using multivariate linear regressions analyses, it turned out that BMI was independently associated with E/A (β = -0.19, p = 0.044) and with E'/A' (β = -0.016, p = 0.021). Ejection fraction, wall motion score index and myocardial S velocities were comparable among the study groups (p > 0.05). These results suggest that while obesity has no adverse effect on the left ventricular systolic function, it has unfavorable consequences on the left ventricular diastolic function in the patients with first STEMI. In contrast, no unfavorable effects of overweight on the left ventricular systolic and diastolic function were detected.

    ABSTRACT: Carotid intima media thickness (CIMT) and carotid plaques (CP) were shown to be independent predictors of mortality in end-stage renal disease (ESRD) patients. In this study, the authors aimed to compare the two dialysis modalities for CIMT and CP presence (CPP). ESRD patients who had been on the same renal replacement therapy for at least 24 months were selected. CIMT, CPP, known risk factors, and laboratory parameters for atherosclerosis were determined for each patient. A total of 77 hemodialysis (HD) patients (68% male, 47.6±17.0 years), 61 continuous ambulatory peritoneal dialysis (CAPD) patients (51% male, 45.3±13.9 years), and 36 age- and sex-matched controls (61% male, 43.3±10.6 years) were included. The mean CIMT (m-CIMT) were 0.99±0.24, 0.86±0.22, and 0.60±0.13 mm in the HD, CAPD, and control groups, respectively (HD vs. CAPD, P=0.001; HD vs. control, P<0.001; and CAPD vs. control, P<0.001). The CPP occurred more frequently in the HD group compared to the CAPD group (64% vs. 39%, respectively, P=0.004). The backward linear and logistic regression analysis of potential confounders revealed that both m-CIMT and CPP was independently associated with dialysis type (beta=0.249, P=0.008; and odds ratio [OR]=4.11, 95% CI, 1.72 to 6.73, P=0.015, respectively). The authors have shown that dialysis type may be an independent predictor of m-CIMT and CPP in long-term ESRD patients.

    ABSTRACT: We aimed to investigate the relationship between plasma asymmetric dimethylarginine (ADMA) levels and heart rate variability (HRV) in diabetic patients. The study included 100 patients (44 men, 56 women) with type 2 diabetes mellitus. The patients were divided into two groups based on the use of oral antidiabetics (n=67; mean age 54.6±7.8 years) or insulin (n=33; mean age 51.6±8.8 years). Plasma ADMA levels were measured and HRV parameters were calculated from 24-hour Holter EKG recordings. The findings were compared with those of a control group consisting of 42 nondiabetic individuals (mean age 52.8±6.2 years). Compared to the control group, plasma ADMA levels were significantly higher (p=0.007) and all HRV parameters were significantly reduced in both diabetic groups. However, ADMA levels and HRV parameters were similar in the two diabetic groups (p>0.05). Correlation analysis showed no significant relationship between plasma ADMA levels and HRV parameters. Our findings show that plasma ADMA levels are increased and HRV is reduced in diabetic patients, indicating that these patients have both endothelial dysfunction and autonomic dysfunction, but plasma ADMA levels cannot be used to evaluate autonomic dysfunction.
