Geriatric nutritional risk index is a predictor of recurrent percutaneous coronary intervention in patients with non-ST segment elevation myocardial infarction.

Aim To investigate the relationship between malnutrition and follow-up cardiovascular (CV) events in non-ST-segment elevation myocardial infarction (NSTEMI).Material and methods A retrospective study was performed on 298 patients with NSTEMI. The baseline geriatric nutritionalrisk index (GNRI) was calculated at the first visit. The patients were divided into three groups accordingto the GNRI: >98, no-risk; 92 to ≤98, low risk; 82 to <92, moderate to high (MTH) risk. The studyendpoint was a composite of follow-up CV events, including all-cause mortality, non-valvular atrialfibrillation (NVAF), hospitalizations, and need for repeat percutaneous coronary intervention (PCI).Results Follow-up data showed that MTH risk group had significantly higher incidence of repeat PCI and all-cause mortality compared to other groups (p<0.001). However, follow-up hospitalizations and NVAFwere similar between groups (p>0.05). The mean GNRI was 84.6 in patients needing repeat PCI and99.8 in patients who did not require repeat PCI (p<0.001). Kaplan Meier survival analysis showed thatpatients with MTH risk had significantly poorer survival (p<0.001). According to multivariate Coxregression analysis, theMTH risk group (hazard ratio=5.372) was associated with increased mortality.Conclusion GNRI value may have a potential role for the prediction of repeat PCI in patients with NSTEMI.

Elabela as a novel marker: Well-correlated with WIfI amputation risk score in lower extremity arterial disease patients.

OBJECTIVE: Worldwide, over 200 million people are diagnosed with lower extremity arterial disease (LEAD). LEAD significantly increases the risk of death and amputation of the lower limb. A new classification system (WIfI) has been proposed to initially assess all patients with ischemic rest pain or wounds and also predicts 1-year amputation risk. Elabela is a bioactive peptide and a part of the apelinergic system, which has beneficial effects on body fluid homeostasis and cardiovascular health. We aimed to investigate serum Elabela levels in LEAD. METHODS: A total of 119 subjects were enrolled in this cross-sectional study, 60 of whom were in the LEAD group and 59 in the control group. All participants underwent physical examination and routine biochemical tests, including serum Elabela levels. Additionally, the LEAD group was divided into subgroups according to the Rutherford classification, ankle-brachial index (ABI) values, and WIfI risk scores. RESULTS: Serum low-density lipoprotein, Elabela, and high-sensitivity C-reactive protein (Hs-CRP) levels were statistically higher in the LEAD group (p=0.002, p<0.001, and p<0.001, respectively). In the Rutherford classification, as the stage increased, Elabela and Hs-CRP levels increased similarly (p<0.001). Elabela levels were statistically found to be positively correlated with Hs-CRP and WIfI amputation score but negatively correlated with ABI (p<0.001). CONCLUSION: Serum Elabela level, which is known to be increased in inflammatory processes, has the potential in predicting low extremity arterial obstruction and WIfI amputation risk in LEAD patients.

Assessment of subclinical left ventricular dysfunction with speckle-tracking echocardiography in hyperthyroid and euthyroid Graves' disease and its correlation with serum TIMP-1.

BACKGROUND: Graves' disease has a multitude of effects on the cardiovascular system. In the detection of subclinical left ventricular dysfunction, speckle-tracking echocardiography is more useful than conventional echocardiography. The aim of the present study was to compare the longitudinal global strain values and venous blood concentration of (tissue inhibitor of metalloproteinase-1) TIMP-1, a regulator of the extracellular matrix, among hyperthyroid patients with Graves' disease, euthyroid patients with Graves' disease and healthy control subjects. MATERIALS AND METHODS: The study enrolled 40 hyperthyroid patients with newly diagnosed Graves' disease, 40 patients with Graves' disease who were euthyroid for at least 6 months and 40 control subjects with normal thyroid function. Participants underwent conventional echocardiography and speckle-tracking echocardiography to obtain segmental and global longitudinal strain values. In addition, the serum TIMP-1 value was assessed in the venous blood samples of the participants. RESULTS: The hyperthyroid Graves' patients showed greater serum TIMP-1 levels versus the control group and the euthyroid Graves' group. Compared to the control group, the TIMP-1 level was also significantly higher in the euthyroid Graves' group. Lower GLS (global longitudinal strain) average and GLS2C, GLS3C, GLS4C values were observed in both the hyperthyroid and euthyroid Graves' patients compared to the control group. The euthyroid Graves' patients and hyperthyroid Graves' patients had similar GLS values. The serum TIMP-1 level was negatively correlated with global strain values. CONCLUSION: Graves' disease coexists with impaired segmental and global longitudinal strain and increased TIMP-1 levels. This coexistence seems to be independent of serum thyroid hormone levels.

Effect of new oral anticoagulants on platelet indices in non-valvular atrial fibrillation patients.

New-generation oral anticoagulants (NOACs) are now preferred as a first-line treatment in the management of atrial fibrillation for prevention of thromboembolic complications. Mean platelet volume (MPV), one of the indicators of increased platelet activity, is also associated with an increased stroke risk in atrial fibrillation patients. The aim of this study was to evaluate changes in MPV, platelet distribution width (PDW) and plateletcrit following use of NOACs. The study included 116 patients with non-valvular atrial fibrillation without previous NOAC use. Complete blood counts, biochemical analyses and echocardiography were performed for all patients. No significant differences were observed in MPV or other platelet indices at 6 months compared to baseline. Our results indicate that MPV and other platelet indices are not affected by NOAC use in non-valvular atrial fibrillation patients.

Transcatheter Treatment of a Symptomatic Giant Iliac Artery Aneurysm with a BeGraft Peripheral Stent in a 2-Year-Old Child.

A 2-year-old girl presented with severe abdominal pain due to a giant iliac artery aneurysm. We embolized the internal iliac artery with microcoils and then eliminated the aneurysmal sac using a BeGraft peripheral stent without any complications. To the best of our knowledge, there are no previous reports of a transcatheter giant iliac artery intervention.

Investigation of leukocyte RHO/ROCK gene expressions in patients with non-valvular atrial fibrillation.

Atrial fibrillation (AF) is an arrhythmia caused by disorganized electrical activity in the atria, and it is an important cause of mortality and morbidity. There is a limited data about Rho/Rho-kinase (ROCK) pathway contribute to AF development. The aim of the present study was to elucidate leukocyte RHO/ROCK gene expressions in patients with non-valvular AF (NVAF). A total of 37 NVAF patients and 47 age and sex-matched controls were included in this study. mRNA was extracted from leukocytes, and real-time polymerase chain reaction was used for gene expression analysis. A marked increase in ROCK1 and ROCK2 gene expressions in patients with NVAF was observed (P<0.0001). The present study detected significant elevations in RHOBTB2, RND3 (RHOE), RHOC, RHOG, RHOH, RAC3, RHOB, RHOD, RHOV, RHOBTB1, RND2, RND1 and RHOJ gene expressions (P<0.01). However, there were marked decreases in CDC42, RAC2, and RHOQ gene expressions in patients with NVAF. No significant modifications were seen in the other Rho GTPase proteins RHOA, RAC1, RHOF, RHOU and RHOBTB3. To the best of our knowledge, the present study is the first to provide data that gene expression of leukocyte RHO/ROCK may contribute to the NVAF pathogenesis through activated leukocytes, which promotes the immune or inflammatory cascade.

Evaluation of subclinical left ventricular dysfunction in overweight people with 3D speckle-tracking echocardiography.

OBJECTIVE: Obesity is associated with cardiovascular risk factors and is a major predictor of cardiovascular disease and mortality. This global burden affects myocardial function by inducing structural and functional alterations. Although subclinical left ventricular (LV) dysfunction is known in obese subjects, there is not sufficient information about overweight people. The aim of the present study was to evaluate subclinical LV dysfunction in overweight people with three-dimensional speckle-tracking echocardiography (3D-STE). METHODS: One hundred eighteen consecutive patients between 18 and 80 years old were enrolled into the study. Patients were divided into three groups according to body mass index (BMI): normal (BMI: 18.5-24.9 kg/m2) (n=35), overweight (BMI: 25-29.9 kg/m2) (n=43), and obese (BMI ≥30 kg/m2) (n=40). 3D-STE was performed, and global longitudinal strain (GLS), global circumferential strain (GCS), global radial strain (GRS), and global area strain (GAS) were measured. 3D-STE results were compared between the groups. RESULTS: The mean age of the patients was 60.97+-8.94 years, and 55.1% of the patient population were male. Mean GCS was -13.5, GLS was -11.9, GRS was 32.3, and GAS was -22. As BMI increased, GCS and all other strain parameters were significantly worse [p<0.001 (normal-overweight), p<0.001 (normal-obese), and p<0.001 (overweight-obese) for GCS, GLS, GRS, and GAS]. A positive linear correlation was observed between BMI and all measured strain parameters (r=0.673, p<0.001 for BMI and GCS). CONCLUSION: 3D-STE is a non-invasive parameter to detect subclinical LV dysfunction, and global strain values are significantly correlated with BMI. Subclinical LV dysfunction was detected in overweight people in addition to obese subjects.

Left atrial appendage 2D-strain assessed by transesophageal echocardiography is associated with thromboembolic risk in patients with atrial fibrillation.

OBJECTIVE: The aim of this study was to determine the relationship of left atrial appendage (LAA) mechanics assessed using 2-dimensional (2D)-strain analysis of the gray scale images obtained during transesophageal echocardiography (TEE) to the conventional LAA functional parameters, CHA2DS2-VASc score, and the presence of spontaneous echo contrast (SEC) and/or LAA thrombus in patients with non-valvular atrial fibrillation (AF). METHODS: The study included 126 patients with AF and 30 controls with a sinus rhythm who were referred for TEE. The global, medial, lateral and apical LAA longitudinal 2D-strain of all patients and the CHA2DS2-VASc score of AF patients were evaluated. RESULTS: The global, medial, lateral, and apical LAA longitudinal 2D-strain results of AF patients were significantly lower than those of the controls and revealed moderate but significant correlations with LAA flow velocity and LAA area change. Patients with a CHA2DS2-VASc score of 0 or 1 had the highest LAA 2D-strain values and the results revealed that the LAAemptying velocity and LAA lateral and medial 2D-strain values were independent correlates of CHA2DS2-VASc score. SEC was detected in 84 patients, of whom, 42 had dense SEC and 27 had thrombus in the LAA. Multivariate analysis indicated that LAA emptying velocity, LAA area change, and LAA medial 2D-strain were independently associated with the presence of dense SEC/thrombus. In ROC analysis, cut-off values for global, medial, apical, and lateral 2D-strain for the presence of dense SEC/ thrombus were 6.0% p=0.011), 8.0% (p=0.032), 6.0% (p=0.033), and 5.4% (p=0.004), respectively. CONCLUSION: Global and regional LAA mechanics were significantly related to conventional LAA functional parameters and to the presence of LAA-dense SEC/thrombus in patients with AF and may be useful as complementary data for estimating future thromboembolism.

Effects of Dust Storms and Climatological Factors on Mortality and Morbidity of Cardiovascular Diseases Admitted to ED.

OBJECTIVE: This study was designed to investigate the effects of Desert Dust Storms and Climatological Factors on Mortality and Morbidity of Cardiovascular Diseases admitted to emergency department in Gaziantep. METHOD: Hospital records, obtained between September 01, 2009 and January 31, 2014, from four state hospitals in Gaziantep, Turkey, were compared to meteorological and climatological data. Statistical analysis was performed by Statistical Package for the Social Science (SPSS) for windows version 24.0. RESULTS: 168,467 patients were included in this study. 83% of the patients had chest pain and 17% of patients had cardiac failure (CF). An increase in inpatient hospitalization due to CF was observed and corresponded to the duration of dust storms measured by number of days. However, there was no significant increase in emergency department (ED) presentations. There was no significant association of cardiac related mortality and coinciding presence of a dust storm or higher recorded temperature. The association of increases in temperature levels and the presence of dust storms with "acute coronary syndrome- (ACS-) related emergency service presentations, inpatient hospitalization, and mortality" were statistically significant. The relationship between the increase in PM10 levels due to causes unrelated to dust storms and the outpatient application, admission, and mortality due to heart failure was not significant. The increase in particle matter 10 (PM) levels due to causes outside the dust storm caused a significant increase in outpatient application, hospitalization, and mortality originated from ACS. CONCLUSION: Increased number of dust storms resulted in a higher prevalence of mortality due to ACS while mortality due to heart failure remained unchanged. Admission, hospitalization, and mortality due to chest pain both dependent and independent of ACS were increased by the presence of dust storms, PM10 elevation, and maximum temperature.

Prediction of subtle left ventricular systolic dysfunction in homozygous and heterozygous familial hypercholesterolemia: Genetic analyses and speckle tracking echocardiography study.

BACKGROUND AND AIMS: Few studies have shown the direct effect of familial hypercholesterolemia (FH) on myocardial systolic function. Studies focused on heterozygote FH patients but not homozygote ones, and they did not perform genetic analyses. We aimed to evaluate all types of patients with FH using the potentially more sensitive speckle tracking echocardiography (STE) technique to identify early left ventricular (LV) dysfunction. METHODS: Genetic analyses of patients with FH were conducted for LDL-receptor, PCSK9, and ApoB100. Nine homozygote, two compound heterozygote, and 82 heterozygote FH patients and 85 healthy subjects were prospectively studied. Longitudinal and circumferential strain measurements and conventional echocardiography findings were obtained. RESULTS: LV ejection fractions were similar for all (homozygote, heterozygote, and control) groups. The LV average longitudinal strain (aLS) and average circumferential strain (aCS) levels were significantly reduced in the homozygote and heterozygote groups when compared with the controls (for aLS, P = .008 (<.001); for aCS, P =< .001). A significant inverse correlation was found between LDL-C levels and LS (P < .001, r = .728) and CS (P < .001, r = .642) for all FH patients. CONCLUSIONS: This study demonstrates the potential of using systolic strain values obtained using 2D STE for determining lipotoxicity in the myocardium owing to hypercholesterolemia. Our study found that cardiac functions of homozygote patients who had the highest cholesterol levels were disrupted at very early ages. Therefore, starting lipid reduction treatment and early reverse LV remodelling therapy at early ages may be beneficial for high-risk patients.
