Hyponatremia and takotsubo syndrome: a review of pathogenetic and clinical implications.

Hyponatremia is a common electrolyte abnormality with important prognostic and therapeutic implications. It might exert detrimental effects on various organ systems including the central nervous system (CNS), bone, and heart along with its potential association with poor quality of life. These adverse effects might be largely mediated through a variety of mechanisms including osmotic stress, dysfunctional transmembrane exchangers, and enhanced oxidative stress.Interestingly, hyponatremia might also have an important association with takotsubo syndrome (TTS) that has been universally considered as a reversible form of cardiomyopathy usually emerging in response to various stressors. In this context, severe hyponatremia was previously reported to serve as a direct trigger of TTS evolution largely through its potential impact on CNS and heart. However, pathogenetic and clinical implications of hyponatremia still need to be thoroughly evaluated in patients with TTS. This paper aims to analyze the clinical features of published cases with TTS primarily triggered by hyponatremia and also aims to discuss the association between hyponatremia and TTS from a broader perspective.

Differential Anxiety Responses in Acute Myocardial Infarction vs. COVID-19 Pneumonia Patients.

Background and Objectives: Amidst the COVID-19 pandemic, concerns about the psychological impact of disease-related anxiety on public health have risen. This study aims to compare general and death anxiety levels between acute coronary artery syndrome and COVID-19 pneumonia patients. Materials and Methods: A cross-sectional study of 132 individuals, including acute myocardial infarction (MI), COVID-19 pneumonia patients, and healthy volunteers from Trakya University Hospital (Turkey), was analyzed. Validated scales like the Beck Anxiety Inventory (BAI), Coronavirus Anxiety Scale Short Form, and Thorson-Powell Death Anxiety Scale (TPDAS) were employed. Demographic data such as age, gender, income levels, employment status, presence of a close relative with COVID-19, and whether participants followed COVID-19-related news were collected and compared across groups with significance level of 0.05 set for all analyses. Results: Among 41 COVID-19, 41 MI, and 50 healthy subjects, the pneumonia group showed highest COVID-19 anxiety (p = 0.01) and BAI scores (p = 0.008). Both COVID-19 and MI patients had significantly higher BAI and TPDAS scores compared to healthy controls (p < 0.001). Factors like female gender (p = 0.004), low education (p = 0.003), current employment (p = 0.008), and low income (p = 0.002) correlated with higher BAI scores. Low income (p = 0.001) and COVID-19 news exposure (p = 0.002) correlated with higher TPDAS scores. Males and married patients had lower anxiety scores (p = 0.008). High income, education, and employment reduced anxiety levels (p = 0.008). TPDAS scores decreased with higher income (p = 0.001), but increased in the MI group (p = 0.002) with COVID-19 news exposure. The multivariate linear regression analysis found that MI and COVID-19 pneumonia were associated with TPDAS; female gender, university education, and COVID-19 pneumonia with the Beck scale; and COVID-19 pneumonia with anxiety scores on the COVID-19 Anxiety scale. Conclusions: This research showcases differing anxiety patterns between illnesses such as MI and COVID-19 pneumonia amidst the pandemic, emphasizing the amplifying influence of media coverage on death-related anxieties. It underscores the imperative of targeted interventions and socioeconomic considerations in managing psychological consequences and formulating responsive public health strategies.

The Effect of SGLT2 Inhibitors on the Development of Contrast-Induced Nephropathy in Diabetic Patients with Non-ST Segment Elevation Myocardial Infarction.

Background and Objectives: Percutaneous procedures using contrast agents are modern diagnosis and treatment methods for cardiovascular diseases. Contrast use may cause nephropathy, especially in diabetic patients. SGLT2 inhibitors have strong cardioprotective and renal protective effects. In our study, we investigated the effectiveness of this drug group in preventing the development of Contrast-Induced Nephropathy (CIN). Materials and Methods: The results of 312 diabetic patients who underwent CAG were analyzed. The study group included 104 DM patients using SGLT2 and the control group did not use SGLT2. These groups were compared with each other in terms of clinical, demographic, and laboratory parameters. Results: The groups were similar characteristics. However, post-CAG creatinine values compared with before the procedure, the development of CIN was observed to be significantly less in the group using SGLT2 inhibitor (p = 0.03). When the results of the multivariate analysis were examined, it was seen that the use of SGLT2 inhibitors significantly reduced the risk of CIN (odds ratio (OR): 0.41, 95% confidence interval (CI): 0,142-0.966, p = 0.004). Conclusions: Our study showed that SGLT2 inhibitors may be protective against the development of CIN, especially in patients with comorbid conditions such as diabetes.

Systemic Immune-Inflammation Index: A Novel Predictor of Coronary Thrombus Burden in Patients with Non-ST Acute Coronary Syndrome.

Background and Objectives: Excessive coronary thrombus burden is known to cause an increase in mortality and major adverse cardiac events (MACEs) in NSTE-ACS (non-ST acute coronary syndrome) patients. We investigated the association between the systemic immune-inflammation index (SII) and coronary thrombus burden in patients with non-ST segment elevation myocardial infarction (NSTEMI) who underwent coronary angiography and percutaneous coronary intervention (PCI). Materials and Methods: A total of 389 patients with the diagnosis of NSTEMI participated in our study. Coronary thrombus burden was classified in the TIMI (thrombolysis in myocardial infarction) thrombus grade scale and patients were divided into two groups: a TIMI thrombus grade 0-1 group (n = 209, 157 males) and a TIMI thrombus grade 2-6 group (n = 180, 118 males). Demographics, angiographic lesion images, coronary thrombus burden, clinical risk factors, laboratory parameters, and SII score were compared between the two groups. Results: The high thrombus burden patient group had a higher neutrophil count, WBC count, platelet count, and systemic immune-inflammation index (SII) (p < 0.001). The receiver operating characteristic (ROC) curve analysis showed that at a cutoff of 1103, the value of SII manifested 74.4% sensitivity and 74.6% specificity for detecting a high coronary thrombus burden. Conclusions: Our study showed that the SII levels at hospital admission were independently associated with high coronary thrombus with NSTEMI.

Cardiac Biomarkers in the Setting of Asthma Exacerbations: a Review of Clinical Implications and Practical Considerations.

PURPOSE OF REVIEW: The present paper aims to highlight clinical implications of elevated cardiac biomarkers and associated myocardial dysfunction in a variety of cardiac and non-cardiac scenarios in patients with an asthma exacerbation, and to propose a basic algorithm for cardiovascular evaluation and triage (and hence, for further management) of these patients primarily based on evaluation of cardiac biomarkers along with basic diagnostic modalities and specific cardiac symptoms in the hospital setting. RECENT FINDINGS: Elevation of cardiac biomarkers in the setting of an asthma exacerbation mostly signifies a new-onset subclinical myocardial dysfunction/injury generally associated with certain asthma-related factors including acute hypoxemia and bronchodilator therapy, and usually has a limited prognostic value in these patients. On the other hand, elevation of these biomarkers in patients with an asthma exacerbation might also denote a variety of certain life-threatening cardiac or non-cardiac conditions associated with significant myocardial dysfunction (acute coronary syndromes (ACSs), sepsis, etc.) that might be masked by the rampant course of the asthma exacerbation, and hence, might possibly go undetected potentially aggravating the prognosis in a portion of these patients. In patients with an asthma exacerbation, it seems imperative to timely diagnose and manage emerging diverse clinical conditions particularly through the guidance of cardiac biomarkers and associated myocardial dysfunction patterns in an effort to improve overall prognosis in these patients.

The etiology and age-related properties of patients with delirium in coronary intensive care unit and its effects on inhospital and follow up prognosis.

Background and purpose: Delirium is a syndrome frequently encountered in intensive care and associated with a poor prognosis. Intensive care delirium is mostly based on general and palliative intensive care data in the literature. In this study, we aimed to investigate the incidence of delirium in coronary intensive care unit (CICU), related factors, its relationship with inhospital and follow up prognosis, incidence of age-related delirium and its effect on outcomes. Methods: This study was conducted with patients hospitalized in CICU of a tertiary university hospital between 01 August 2017 and 01 August 2018. Files of all patients were examined in details, and demographic, clinic and laboratory parameters were recorded. Patients confirmed with psychiatry consultation were included in the groups of patients who developed delirium. Patients were divided into groups with and without delirium developed, and baseline features, inhospital and follow up prognoses were investigated. In addition, patients were divided into four groups as <65 years old, 65-75 yo, 75-84 yo and> 85 yo, and the incidence of delirium, related factors and prognoses were compared among these groups. Results: A total of 1108 patients (mean age: 64.4 ± 13.9 years; 66% men) who were followed in the intensive care unit with variable indications were included in the study. Of all patients 11.1% developed delirium in the CICU. Patients who developed delirium were older, comorbidities were more frequent, and these patients showed increased inflammation findings, and significant increase in inhospital mortality compared to those who did not develop delirium (p<0.05). At median 9-month follow up period, rehospitalization, reinfarction, cognitive dysfunction, initiation of psychiatric therapy and mortality were significantly higher in the delirium group (p<0.05). When patients who developed delirium were divided into four groups by age and analyzed, incidence of delirium and mortality rate in delirium group were significantly increased by age (p<0.05). Conclusion: Development of delirium in coronary intensive care unit is associated with increased inhospital and follow up morbidity and mortality. Delirium is more commonly seen in geriatric patients and those with comorbidity, and is associated with a poorer prognosis. High-risk patients should be more carefully monitored for the risk of delirium.

The effect of thyroid functions on contrast-induced nephropathy in patients undergoing coronary angiography and percutaneous coronary intervention.

OBJECTIVE: To investigate the effects of thyroidism on the development of contrast-induced nephropathy in patients undergoing coronary angiography and percutaneous coronary intervention. METHODS: The prospective, observational study was conducted at Trakya University Faculty of Medicine, Edirne, Turkey, from October 1, 2016, to October 1, 201 7, and comprised patients with hypothyroidism, hyperthyroidism and euthyroid patients. Thyroid and renal functions were evaluated from blood samples taken before the procedure. The definition of contrast-induced nephropathy included absolute (0.5 mg/dL) or relative increase (25%) in serum creatinine 48-72 h after exposure to a contrast agent compared with baseline serum creatinine values. SPSS 10 was used for data analysis. RESULTS: Of the 162 patients, 58(35.8%) had hypothyroidism, 47(29%) hyperthyroidism and 57(35.2%) euthyroid. Contrast-induced nephropathy was significantly higher in hypothyroid and hyperthyroid subjects compared to euthyroid group (p<0.001 each). Univariate analysis showed contrast volume, procedure, albumin value, hypothyroidism and hyperthyroidism to be independent predictors of contrast-induced nephropathy (p<0.05 each), but multivariate analysis only showed hypothyroidism and the hyperthyroidism as the independent predictors (p<0.01 each). CONCLUSIONS: Contrast-induced nephropathy rate was increased in patients with malfunctioning thyroid, Hypothyroidism and hyperthyroidism were found to be independent predictors of contrast-induced nephropathy.

The Inflammation-Based Glasgow Prognostic Score as a Prognostic Factor in Patients with Intensive Cardiovascular Care Unit.

Background: The Glasgow prognostic score (GPS), which is obtained from a combination of C-reactive protein (CRP) and serum albumin level, predicts poor prognoses in many cancer types. Systemic inflammation also plays an important role in pathogenesis of cardiovascular diseases. In this study, we aimed to investigate the effect of inflammation-based GPS on in-hospital and long-term outcomes in patients hospitalized in intensive cardiovascular care unit (ICCU). Methods: A total of 1004 consecutive patients admitted to ICCU were included in the study, and patients were divided into three groups based on albumin and CRP values as GPS 0, 1, and 2. Patients' demographic, clinic, and laboratory findings were recorded. In-hospital and one-year mortality rates were compared between groups. Results: Mortality occurred in 109 (10.8%) patients in in-hospital period, 82 (8.1%) patients during follow-up period, and thus, cumulative mortality occurred in 191 (19.0%) patients. Patients with a high GPS score had a higher rate of comorbidities and represented increased inflammatory evidence. In the multivariate regression model there was independent association with in-hospital mortality in GPS 1 patients compared to GPS 0 patients (Odds ratio, (OR); 5.52, 95% CI: 1.2⁻16.91, p = 0.025) and in GPS 2 patients compared to GPS 0 patients (OR; 7.01, 95% CI: 1.39⁻35.15, p = 0.018). A higher GPS score was also associated with a prolonged ICCU and hospital stay, and increased re-hospitalization in the follow-up period. Conclusion: Inflammation based GPS is a practical tool in the prediction of worse prognosis both in in-hospital and one-year follow-up periods in ICCU patients.

Cardiac Magnetic Resonance Imaging and Transthoracic Echocardiography: Investigation of Concordance between the Two Methods for Measurement of the Cardiac Chamber.

Background and objectives: Cardiac magnetic resonance (CMR) imaging is the gold standard method for the detection of ventricular volumes and myocardial edema/scar. Transthoracic echocardiography (TTE) imaging is primarily used in the evaluation of cardiac functions and chamber dimensions. This study aims to investigate whether the chamber diameter measurements are concordant with each other in the same patient group who underwent TTE and CMR. Materials and Methods: The study included 41 patients who underwent TTE and CMR imaging. Ventricular and atrial diameter measurements from TTE-derived standard parasternal long axis and apical four-chamber views and CMR-derived three- and four-chamber views were recorded. The concordance between the two methods was compared using intra-class correlation coefficients (ICC) and Bland-Altman plots. Results: Of the patients, 25 (61%) were male and the mean age was 48.12 ± 16.79. The mean ICC for LVDD between CMR observers was 0.957 (95% CI: 0.918-0.978), while the mean ICC between CMR and TTE measurements were 0.849 (95% CI: 0.709-0.922) and 0.836 (95% CI: 0.684-0.915), respectively. The mean ICC for the right ventricle between CMR observers was 0.985 (95% CI: 0.971-0.992), while the mean ICC between CMR and TTE measurements were 0.869 (95% CI: 0.755-0.930) and 0.892 (95% CI: 0.799-0.942), respectively. Passing-Bablok Regression and Bland-Altman plots indicated high concordance between the two methods. Conclusions: TTE and CMR indicated high concordance in chamber diameter measurements for which the CMR should be considered in patients for whom optimal evaluation with TTE could not be performed due to their limitations.

The Relationship between Diffusion-Weighted Magnetic Resonance Imaging Lesions and 24-Hour Rhythm Holter Findings in Patients with Cryptogenic Stroke.

BACKGROUND AND OBJECTIVES: Cranial magnetic resonance imaging findings of patients considered to be cryptogenic stroke may be useful in determining the clinical and prognostic significance of arrhythmias, such as atrial premature beats and atrial run attacks, that are frequently encountered in rhythm Holter analysis. This study was conducted to investigate the relationship between short atrial runs and frequent premature atrial contractions detected in Holter monitors and infarct distributions in cranial magnetic resonance imaging of patients diagnosed with cryptogenic stroke. MATERIALS AND METHODS: We enrolled the patients with acute ischemic stroke whose etiology were undetermined. We divided the patients in two groups according to diffusion-weighted magnetic resonance imaging as single or multiple vascular territory acute infarcts. The demographic, clinical, laboratory, echocardiographic, and rhythm Holter analyses were compared. RESULTS: The study investigated 106 patients diagnosed with cryptogenic stroke. Acute cerebral infarctions were detected in 31% of the investigated patients in multiple territories and in 69% in a single territory. In multivariate logistic regression analysis, the total premature atrial contraction count (OR = 1.002, 95% CI: 1.001⁻1.004, p = 0.001) and short atrial run count (OR = 1.086, 95% CI: 1.021⁻1.155, p = 0.008) were found as independent variables that could distinguish between infarctions in a single or in multiple vascular territories. CONCLUSIONS: Rhythm Holter monitoring of patients with infarcts detected in multiple vascular territories showed significantly higher premature atrial contractions and short atrial run attacks. More effort should be devoted to the identification of cardioembolic etiology in cryptogenic stroke patients with concurrent acute infarcts in the multiple vascular territories of the brain.

The Effect of Thyroid Stimulating Hormone Level Within the Reference Range on In-Hospital and Short-Term Prognosis in Acute Coronary Syndrome Patients.

Background and objectives: Despite being within the normal reference range, changes in thyroid stimulating hormone (TSH) levels have negative effects on the cardiovascular system. The majority of patients admitted to hospital with acute coronary syndrome (ACS) are euthyroid. The aim of this study was to investigate the effect of TSH level on the prognosis of in-hospital and follow-up periods of euthyroid ACS patients. Materials and Methods: A total of 629 patients with acute coronary syndrome without thyroid dysfunction were included in the study. TSH levels of patients were 0.3-5.33 uIU/mL. Patients were divided into three TSH tertiles: TSH level between (1) 0.3 uIU/mL and <0.90 uIU/mL (n = 209), (2) 0.90 uIU/mL and <1.60 uIU/mL (n = 210), and (3) 1.60 uIU/mL and 5.33 uIU/mL (n = 210). Demographic, clinical laboratory, and angiographic characteristics were compared between groups in terms of in-hospital and follow-up prognosis. Results: Mean age was 63.42 ± 12.5, and 73.9% were male. There was significant difference between tertiles in terms of TSH level at admission (p < 0.001), the severity of coronary artery disease (p = 0.024), in-hospital mortality (p < 0.001), in-hospital major hemorrhage (p = 0.005), total adverse clinical event (p = 0.03), follow-up mortality (p = 0.022), and total mortality (p < 0.001). In multivariate logistic regression analysis, the high-normal TSH tertile was found to be cumulative mortality increasing factor (OR = 6.307, 95%; CI: 1.769-22.480; p = 0.005) during the 6-month follow-up period after hospitalization and discharge. Conclusions: High-normal TSH tertile during hospital admission in euthyroid ACS patients is an independent predictor of total mortality during the 6-month follow-up period after hospitalization and discharge.

[Levels of awareness of occupational and general cardiovascular risk factors among metal industry employees]. / Metal sektörü çalisanlarinin mesleki ve genel kardiyovasküler risk faktörleri bilgi düzeyleri.

OBJECTIVE: Long-term exposure to physical, chemical, ergonomic and psychosocial environmental factors may lead to occupational cardiovascular disease in metal industry employees. This study aimed to determine levels of knowledge levels regarding occupational and cardiovascular risk factors among metal industry employees. METHODS: The study was conducted between 2nd and 6th June 2014 with the participation of 82 employees. All were working in a medium-sized workplace in the metal industry. Data were collected by means of a questionnaire, which included socio-demographic characteristics and occupational cardiovascular risk factors, and a scale developed by Arikan et al. to measure awareness levels of risk factors for cardiovascular diseases (CARRF-KL). RESULTS: The mean age of employees was 39.97±8.44. Of the participants, 58.5% stated that they had knowledge on cardiac disease risk factors. The mean CARRF-KL score was found to be 18.65±4.04. The percentage of employees stating that they had no knowledge on the occupational risks for such diseases was 79.3%, while 19.5% stated that job stress caused cardiac diseases. One individual (1.2%) stated that one of the chemical solvents used in the working environment was a risk factor. CONCLUSION: Although awareness among metal industry employees of cardiovascular risk factors was above average, it was determined that they do not have adequate information on occupational risk factors. Prolonged and unprotected levels exposure to environmental factors constitute a risk for cardiovascular disease. This information is important for the development of preventive cardiology.

Comparison of subclinical left and right ventricular systolic dysfunction in non-dipper and dipper hypertensives: impact of isovolumic acceleration.

UNLABELLED: Abstract Objectives: To evaluate subclinical left ventricular and right ventricular systolic impairment in dipper and non-dipper hypertensives by using isovolumic acceleration. METHODS: About 45 normotensive healthy volunteers (20 men, mean age 43 ± 9 years), 45 dipper (27 men, mean age 45 ± 9 years) and 45 non-dipper (25 men, 47 ± 7 years) hypertensives were enrolled. Isovolumic acceleration was measured by dividing the peak myocardial isovolumic contraction velocity by isovolumic acceleration time. RESULTS: Non-dippers indicated lower left ventricular (2.2 ± 0.4 m/s(2) versus 2.8 ± 1.0 m/s(2), p < 0.01) and right ventricular isovolumic acceleration values (2.8 ± 0.8 m/s(2) versus 3.5 ± 1.0 m/s(2), p = 0.012) compared with dippers. Left ventricular mass index (p = 0.001), interventricular septal thickness (p = 0.002) and myocardial performance index (p < 0.001) were negatively correlated with left ventricular isovolumic acceleration. Left ventricular septal thickness (p = 0.002), mass index (p = 0.001) and right ventricular myocardial performance index (p < 0.001) were negatively correlated with right ventricular isovolumic acceleration. CONCLUSION: The present study demonstrates that non-dipper hypertensives have increased left and right ventricular subclinical systolic dysfunction compared with dippers. Isovolumic acceleration is the only echocardiographic parameter in predicting this subtle impairment.

The REDUCED (a RandomisED stUdy Comparing standard systemic anticoagulation thErapy to low Dose intracoronary anticoagulation therapy for elective percutaneous coronary intervention) trial. A novel pharmacologic regime for elective percutaneous coronary intervention.

AIM: This study tried to determine the efficacy and safety of low-dose intracoronary unfractionated heparin (UFH) in elective percutaneous coronary intervention (PCI). METHODS: Two-hundred patients who underwent elective PCI of an uncomplicated lesion were included into the study. The patients were assigned to either a control group (70-100 IU/kg intravenous UFH) or a low-dose intracoronary UFH (1,000 IU intracoronary UFH) group. RESULTS: At 30 days, the primary end point (composite of death, myocardial infarction, or urgent target vessel revascularization) was similar in both groups [intracoronary UFH group, 1.0%; control group, 2.0%; odds ratio; 0.49 (95% CI: 0.04 - 5.54), P = 0.56]. Post-procedural myocardial injury (according to CK-MB, P = 0.91; according to Tn I, P = 0.81) and bleeding events (based on TIMI criteria, P = 0.33; based on STEEPLE criteria, P = 0.20) were similar in the control and intracoronary groups. The primary end point at 6 months was also similar between the two groups (P = 0.33). Moreover, the health care cost at 30 days of follow-up was lower in the intracoronary group than in the control group (1,016 ± 54 $/patient vs 1,110 ± 102 $/patient, P < 0.001). CONCLUSION: This pilot study suggests that elective PCI could be safely performed with low-dose intracoronary UFH in the treatment of uncomplicated lesions and at a lower cost as compared to standard systemic anticoagulation.These results should be confirmed by further studies.

A Novel Potential Biomarker for Predicting the Development of Septic Embolism in Patients with Infective Endocarditis: Systemic Coagulation Inflammation Index.

OBJECTIVE: Early diagnosis of septic emboli is crucial to prevent the associated morbidity and mortality. This study aimed to examine the relationship between the systemic coagulation inflammation index (SCII) and septic embolism in patients with infective endocarditis (IE). METHODS: We retrospectively analyzed the data of 167 IE patients treated at our tertiary care hospital between January 2007 and January 2023. We collected information on symptoms, comorbidities, predisposing valve diseases, prosthetic valves, devices, history of injectable drug use, blood culture results, echocardiographic findings, and complications. The SCII index was calculated using the formula: [platelet count (PLT) × fibrinogen level (g/L) / white blood cell count (WBC)]. RESULTS: The mean age of the patients was 61 years, with rheumatic valve disease being the most common predisposing factor. The most common etiologic microorganism was Staphylococcus species. Septic embolism developed in 25.7% of the patients, with the cerebral system being the most commonly affected (46.5%). The SCII was identified as an independent marker for the development of septic embolism. Receiver operating characteristic (ROC) curve analysis confirmed that an optimal SCII value of 59.8 predicted septic emboli with a sensitivity of 65.1% and a specificity of 59.6% (area under the ROC curve: 0.649 [95% confidence interval (CI): 0.556 - 0.743], P = 0.004). CONCLUSION: This study demonstrates that high SCII levels are an independent predictor for the development of septic embolism in patients with IE.

The importance of speckle tracking echocardiography in the evaluation of cardiac functions in patients with rheumatoid arthritis.

Objectives: In this study, we aimed to analyze the layer-specific strain values obtained by speckle tracking echocardiography (STE) method in the determination of subclinical cardiac dysfunction in rheumatoid arthritis (RA) patients. Patients and methods: Between February 2019 and October 2019, a total of 63 female RA patients (mean age: 51.82±6.07 years; range, 40 and 65 years) who had a confirmed diagnosis were included. Thirty-one age-matched female healthy individuals (mean age: 50.71±5.37 years; range, 40 and 65 years) were selected as the control group. The patients were divided into three groups according to the duration of disease as <5 years, 5-10 years and >10 years. The Disease Activity Score in 28 joint - C-reactive protein (CRP) was used to determine disease activation. The standard assessment included complete serum CRP, anti-cyclic citrullinated peptide, rheumatoid factor, N-terminal pro B-type natriuretic peptide (NT-proBNP), and homocysteine. Global longitudinal strain (GLS) analysis was performed with STE. Results: The NT-proBNP values were found to be higher in RA patients compared to the control group (p=0.044). In terms of conventional echocardiographic parameters, a significant difference between E/A and E/E' ratios was observed (p<0.001 and p=0.015). Endocardium, transmural, and epicardium GLS values obtained by STE were found to be lower in RA patients (p<0.05). The left ventricular (LV) GLS values worsened, as the duration of disease increased (p<0.05). There was a significant correlation between RA disease activity and LV GLS values, showing that increasing levels of disease activity was associated with worse LV GLS (r=0.583, p<0.01 and r=0.681, p<0.01 and r=0.689, p<0.01 for endocardium, transmural and epicardium, respectively). Conclusion: Our study results suggest that the layer-specific GLS values obtained by STE decrease in RA patients.

Which aerobic exercise is more effective in Parkinson's patients? Cycle ergometer versus body weight-supported treadmill.

Objectives: The study aimed to evaluate the effects of aerobic exercise applied with bodyweight-supported treadmill (BWSTT) or cycle ergometer (CE) in Parkinson's patients. Patients and methods: In the prospective single-blind study, 38 Parkinson's patients with Hoehn-Yahr Stage 1-3 were randomized into the CE and BWSTT groups between May 2019 and March 2020. Evaluations before and after six weeks of treatment included a six-min walking test with a software device as the primary outcome and functional balance tests (Tinetti balance and gait test, one-leg stance balance test) as secondary outcomes. Both groups received 40 min of aerobic exercise three days per week with conventional rehabilitation and various methods. CE and BWSTT groups were created. The aerobic exercise program was designed based on treatment recommendations for Parkinson's patients of the American College of Sports Medicine (CE test, with the Karvonen formula, 40-60% reserve). Posttreatment and pretreatment evaluations were compared within and between groups. Results: The six-week aerobic exercise program was completed by 16 participants (9 males, 7 females; mean age: 65.9±8.1; range, 47 to 78 years) in the CE group and 15 participants (9 males, 6 females; mean age: 62.5±7.5; range, 49 to 79 years) in the BWSTT group. The demographic characteristics of the patients were similar. Primary and secondary outcomes were significantly different after treatment than before treatment in both groups. There were no significant differences between the groups in outcomes. Conclusion: The results showed that both methods are effective and not superior to each other. Aerobic exercise programs led by experienced clinicians can benefit patients.

Hypertension and Occupational Health: A General Overview and Expert Consensus Suggestions.

Hypertension is a common public health issue, and its incidene increases parallel to age. It is inevitable that certain occupational conditions may pose risks for high blood pressure or cause difficulties in managing blood pressure. Working under specific circumstances may compromise the safety of individuals with hypertension and potentially others. Therefore, it is crucial to implement activities that enhance awareness of hypertension, to ensure regular periodic examinations, and to establish necessary precautions in the workplace for the health of employees and the public. Given the limited resources offering guidance on hypertension in the context of occupational health, the authors of this paper, who hail from different disciplines, have prepared a set of consensus-based suggestions.

TyG index as a predictor of spontaneous coronary artery dissection in young women.

OBJECTIVE: Spontaneous coronary artery dissection (SCAD) is a rare but potentially life-threatening pathology and cases are especially seen in women under 50 years of age and with relatively fewer cardiovascular risk factors. Although risk factors facilitating the development of SCAD have been defined in the literature, modifiable risk factors remain unclear. In this study, it was aimed to investigate the relationship between the triglyceride glucose index (TyG) and the development of SCAD in the population of young women. METHODS: The results of 281 patients were analyzed and compared with each other in terms of clinical, demographic, laboratory parameters, and coronary angiography results. RESULTS: The mean age was 45 years and all of them were female. When the groups were compared, the TyG and inflammatory parameters were higher in the SCAD group (p < 0.001). When these two groups with low cardiovascular risk factors were compared in logistic regression analysis, high TyG was found to be an independent predictor of SCAD development in young women (p < 0.001). CONCLUSION: As a result, our study shows that the development of these non-atherosclerotic conditions can be predicted by simple biochemical tests in young women with low atherosclerotic cardiovascular risk factors.

Comparison of Myocardial Perfusion Scintigraphy and Coronary Angiography Results in Breast Cancer Patients Treated with Radiotherapy.

Breast cancer is the most common type of malignancy in women and radiotherapy (RT) is an important part of treatment. Although it reduces cancer recurrence, it has been shown to cause accerelerated athnerosclerosis. This study aimed to compare the results of myocardial perfusion scintigraphy (MPS) for ischemia investigation with coronary angiography (CAG) findings and to investigate the effect of RT on the development of coronary artery disease in breast cancer patients who underwent RT. The results of 660 patients were analyzed and compared with each other in terms of clinical, demographic, laboratory parameters and MPS results. The mean age was 57.5 years and all of them were female. When the groups were compared, the Gensini score and marking of the left anterior descending artery (LAD) area as ischemic area localization were found more, but angiographically, the rate of severe stenosis in the area indicated by MPS was found to be lower in the RT group (p < 0.001). While the sensitivity of MPS in the RT group was 67.5% and non-RT group was 88.5% (p < 0.001), the result of our study shows that the sensitivity of the MPS test is significantly lower in the patient group receiving RT.
