Left atrial function index and left atrial electromechanical functions in anxiety disorders.

BACKGROUND: There is a close linkage between anxiety disorders (ADs), and development of cardiovascular disease (CVD) and atrial fibrillation (AF). We aimed to investigate left atrial function index (LAFI) and its components, LA mechanical functions and atrial conduction times in AD patients and age- and gender-matched control group patients for the first time in the literature. METHODS: A total of 48 AD patients and 33 healthy subjects were enrolled to the study prospectively. Echocardiographic parameters including two-dimensional conventional echocardiography, diastolic functions, LA mechanical functions, LAFI, atrial conduction times and atrial electromechanical delay (AEMD) were calculated. RESULTS: The velocity-time integral of the LV outflow tract (LVOT-VTI), LAFI and LA conduit volume were significantly lower in AD patients. Atrial electromechanical coupling as established from lateral mitral annulus (PA lateral) was significantly higher in AD group than control group. Inter-AEMD and left intra-AEMD were also higher in AD group compared to control group. Age, gender, body surface area (BSA), conduit volume, LVOT-VTI and LAFI were significant factors associated with AD in univariate analysis. However, only BSA and LVOT-VTI (Odds ratio [OR]: 0.79, 95 CI%: 0.66-0.95, p = 0.013) were independently associated with AD in multivariate analysis. Age, gender, conduit volume and LAFI (OR: 0.25, 95 CI%: 0.03-2.12, p = 0.204) were not found to be independent associates of AD. CONCLUSION: LAFI is impaired in patients suffering from AD compared to their age- and gender-matched counterparts but this impairment originates from lower levels of LVOT-VTI calculations in AD patients. Thus, LVOT-VTI, but not LAFI, is independently associated with AD.

The Effect of Septoplasty on Endothelial Function in Patients With Marked Nasal Septal Deviation.

BACKGROUND: It is known that nasal septal deviation (NSD) has negative effects on the cardiovascular system, but the possible pathophysiological mechanisms of these effects still need to be explained. The aim of this study was to investigate the endothelial dysfunction (ED) caused by NSD and the effects of septoplasty on it. METHODS: The study included 40 patients between the ages of 18 to 50 years with a marked NSD indication for septoplasty and 40 healthy age-and gender-matched individuals. Nasal obstruction symptom evaluation scale was used to evaluate the severity of nasal obstruction and the effectiveness of septoplasty. All participants underwent detailed cardiac examination and ultrasonographic measurement of flow-mediated dilatation (FMD). The same cardiac evaluations and nasal obstruction symptom evaluation scale assessments were repeated in the patient group at the postoperative 3rd month. RESULTS: The mean FMD value in the control group was significantly higher than preoperative FMD in the patient group (9.1 ±â€Š2.9 versus 7.6 ±â€Š2.4, P  = 0.024). In the patient group, preoperative and postoperative FMD values were measured as 7.6 ±â€Š2.4 and 9.0 ±â€Š2.7, respectively, and there was a significant difference between them (P = 0.032). There was no significant difference in FMD values between the control group and postoperative patient group (P = 0.925). CONCLUSIONS: This study shows that NSD can cause ED, which is a precursor of atherosclerosis, and that successful septoplasty can improve ED.

Noninvasive assessment of subclinical atherosclerosis in patients with rosacea.

BACKGROUND: Rosacea is a chronic, inflammatory cutaneous disorder that is characterized by remissions and relapses that commonly occur in patients over the age of 30 years. There have been many studies in literature evaluating the relationship between cardiovascular disease and psoriasis, which is a chronic inflammatory disease; however, there have been very few studies to date evaluating the relationship between rosacea and cardiovascular disease risk. METHODS: The study included 52 consecutive rosacea patients and 52 healthy controls matched for age, gender and Body Mass Index. Demographic data, anthropometric measurements, lipid parameters, C-reactive protein (CRP), epicardial fat thickness (EFT) and carotid intima-media thickness (CIMT) were recorded. RESULTS: The main finding of the present study is the significantly higher EFT (P˂0.001) and CIMT (P˂0.001) values identified in patients with rosacea than in the control group and CRP (P=0.004), total cholesterol (P=0.003) and low-density lipoprotein (P=0.004) levels were also significantly higher in the rosacea group. EFT was significantly correlated with CIMT in the rosacea group (P=0.041). Total cholesterol (OR=1.032, P=0.017), CIMT (OR=7.391, P˂0.001) and EFT (OR=3.959, P=0.036) were independently associated with rosacea. CONCLUSIONS: Clinicians should be aware of the risk of cardiovascular disease when presenting with conditions involving persistent subclinical inflammation, as in the case of rosacea. EFT and CIMT measurements, which are noninvasive, easily accessible and cheap, can be useful to determine cardiovascular risk in rosacea patients.

[Evaluation of the relationship between erectile dysfunction and epicardial fat tissue thickness and carotid intima-media thickness in patients with newly diagnosed hypertension]. / Yeni tani konmus hipertansiyonu olan hastalarda erektil disfonksiyon ile epikardiyal yag dokusu kalinligi ve karotis intima-media kalinligi arasindaki iliskinin degerlendirilmesi.

OBJECTIVE: This study is an investigation of the relationship between erectile dysfunction and epicardial adipose tissue and carotid intima-media thickness, which are indicators of endothelial dysfunction and subclinical atherosclerosis, in patients with newly diagnosed hypertension. METHODS: The epicardial adipose tissue and carotid intima-media thickness of 101 male patients with newly diagnosed hypertension were measured using echocardiography between May 1, 2018 and May 31, 2019. Evaluation of erectile dysfunction was performed using the 5-item version of the International Index of Erectile Function (IIEF-5) in a face-to-face interview in the urology outpatient clinic. The data of patients with and without erectile dysfunction were compared. RESULTS: There was a significant relationship between the presence and severity of erectile dysfunction and epicardial fat tissue and carotid intima-media thickness in patients with newly diagnosed hypertension. Left ventricular diastolic function was found to be more impaired in patients with erectile dysfunction. CONCLUSION: Erectile dysfunction was determined to be related to increased epicardial fat tissue and carotid intima-media thicknesses in patients with newly-diagnosed hypertension.

The relation of endocan and galectin-3 with ST-segment resolution in patients with ST-segment elevation myocardial infarction.

BACKGROUND: ST-segment elevation myocardial infarction (STEMI) remains a leading cause of morbidity and mortality around the world. In patients with STEMI undergoing primary percutaneous coronary intervention (PPCI), electrocardiographic measures of ST-segment resolution (STR) may give information about the myocardial perfusion and poor prognosis. OBJECTIVES: To investigate the relation of endocan and galectin-3 levels with STR in STEMI patients. MATERIAL AND METHODS: In this cross-sectional study, 98 consecutive patients undergoing PPCI for STEMI were enrolled. Synergy between percutaneous coronary intervention with taxus and cardiac surgery (SYNTAX) scores were recorded. Electrocardiograms were assessed at baseline and 60 min after PPCI. According to STR levels, patients undergoing PPCI (n = 98) were divided into complete STR group (≥70%, n = 53) and incomplete STR group (<70%, n = 45). RESULTS: Serum glucose, total cholesterol, low-density lipoprotein cholesterol, SYNTAX score, endocan and galectin-3 levels were significantly higher and ejection fraction was significantly lower in the incomplete STR (<70%) group (p < 0.05 for all). Body mass index (BMI) (p = 0.046) and galectin-3 (p = 0.037) were independently associated with the SYNTAX score. Endocan (p = 0.044) and galectin-3 (p = 0.017) were independent predictors of incomplete STR. CONCLUSIONS: In patients with STEMI, the levels of endocan and galectin-3 may be helpful in identifying patients with a higher risk of insufficient myocardial perfusion and worse clinical outcome after PPCI.

The heart rate recovery is impaired in participants with premature ejaculation.

Premature ejaculation (PE) is one of the most common sexual disorders in men. Excessive activity of the sympathetic nervous system is considered as one of the pathological mechanisms of PE. Heart rate recovery (HRR) is a noninvasive and easily applicable method for evaluating autonomic functions. We aimed to investigate the relationship between PE and HRR. This cross-sectional study included 42 consecutive patients with lifelong PE and 98 healthy volunteers. All participants underwent stress tests according to age-dependent target heart rates outlined in the Bruce protocol. When the maximal heart rate was reached in the stress test, intensive exercise was terminated and electrocardiographic records were obtained for 3 min in the cool-down period. The HRR indices were calculated by subtracting the heart rate at first, second and third minutes from the maximal HR. The two groups were similar in terms of age, body mass index, serum glucose and lipid parameters. HRR indices were significantly lower in the PE group compared with the control group (p < .05 for all). Common factors that affect equilibrium of sympathetic and parasympathetic nervous systems may be involved in the PE and abnormal HRR etiopathogenesis. The cause-and-effect relationship can be more clearly demonstrated with large-scale, prospective studies.

Acute effects of electronic cigarette smoking on ventricular repolarization in adults.

BACKGROUND: Electronic cigarette (e-cigarette) use is constantly increasing. However, the association between e-cigarette use and ventricular arrhythmia is unknown. Thus, in this study, we aimed to evaluate the markers of ventricular repolarization such as QT interval, corrected QT (QTc), QT dispersion (QTd), peak-to-end interval of the T wave (Tp-e), corrected Tp-e and Tp-e/QT ratios in e-cigarette users. METHODS: The study population consisted 36 e-cigarette users and 40 healthy subjects. Ventricular repolarization parameters were obtained from 12-lead resting electrocardiogram. Ventricular repolarization parameters of the groups were compared. RESULTS: Basal demographic and laboratory data were similar in both groups. According to the electrocardiographic parameters, the Tp-e interval, corrected Tp-e, and Tp-e/QT ratio were significantly higher in individuals using e-cigarettes than in control subjects [74.9±6.4 milliseconds (ms) vs. 80.1±4.1ms, <0.001; 82.9±7.5 ms vs. 87.8±6.3 ms, p=0.003; 0.20±0.01 vs. 0.21±0.01, p=0.002; respectively]. CONCLUSION: This is the first study to show the disruption of ventricular repolarization properties in e-cigarette users. E-cigarette use in terms of public health leads to augmentation of transmural dispersion of repolarization, which may be potential indicator of ventricular arrhythmogenesis.

The Nonalcoholic Fatty Liver Disease Fibrosis Score Is Related to Epicardial Fat Thickness and Complexity of Coronary Artery Disease.

Nonalcoholic fatty liver disease (NAFLD) is a hepatic manifestation of the metabolic syndrome and is associated with cardiovascular disease (CVD). The NAFLD Fibrosis Score (NFS) is an index used for the detection of liver fibrosis. We investigated the relationship between NFS and complexity of coronary artery disease (CAD). In this cross-sectional study, 109 patients with CAD and 50 patients without CAD were enrolled. Demographic data, laboratory parameters, epicardial fat thickness (EFT), NFS, and Synergy between percutaneous coronary intervention with Taxus and cardiac surgery (SYNTAX) score were recorded. Waist circumference, fasting glucose, low-density lipoprotein cholesterol (LDL-C), EFT, and NFS were significantly higher in the CAD group (P < .05). High-density lipoprotein cholesterol (HDL-C) and ejection fraction were significantly lower in the CAD group (P < .05). The SYNTAX score was positively correlated with fasting glucose, LDL-C, EFT, and NFS and negatively correlated with HDL-C (P < .05). The NFS was positively correlated with EFT (P = .019). Multivariate linear regression analysis revealed that NFS (P = .012), EFT (P < .001), and LDL-C (P = .001) were independently associated with the SYNTAX score. In conclusion, NFS, as a marker of NAFLD, could identify patients at higher risk of CVD.

Increased epicardial fat thickness and carotid intima-media thickness in migraine patients.

BACKGROUND: Migraine is a common and debilitating neurological disorder characterized with episodic attacks. Epicardial fat is metabolically active and is an important predictor of metabolic and vascular diseases. We aimed to examine whether the echocardiographic measurement of epicardial fat thickness (EFT) and carotid intima-media thickness (CIMT) is increased in patients with episodic migraine (EM). METHODS: We studied 96 volunteers, including 48 patients with EM (mean age 40.10 ± 10 years, 41 female patients) and 48 healthy subjects (mean age 42.69 ± 10 years, gender is the same). All necessary biochemical parameters were analyzed; subsequently, EFT and CIMT were measured in all subjects. The migraine characteristics of the patients were questioned in detail. RESULTS: The patients with EM had a significantly higher EFT than the control group (5.34 ± 1.02 vs. 4.41 ± 0.68; P < 0.001) and CIMT was also found to be high (median 6.70 vs. 5.60; P < 0.001). Furthermore, there was a positive correlation between EFT and duration of disease and monthly frequency (r = 0.730; P < 0.001). EFT was significantly correlated with CIMT in the migraineurs (P < 0.001). As an optimal cut-off point, a high-risk EFT value of 5.54 mm was determined to predict EM, with 58.3% sensitivity and 96.8% specificity. CONCLUSION: We found that EFT and CIMT were significantly higher in EM patients than in healthy individuals. Increased EFT may be a new risk factor in migraine patients especially in patients with increased pain frequency.

Vitamin D, vitamin D binding protein, vitamin D receptor levels and cardiac dysautonomia in patients with multiple sclerosis: a cross-sectional study / Vitamina D, proteína de ligação à vitamina D, níveis de receptores de vitamina D e disautonomia cardíaca em pacientes com esclerose múltipla: um estudo transversal

ABSTRACT Vitamin D is a pleiotropic steroid hormone that modulates the autonomic balance. Its deficiency has been described as an environmental risk factor for multiple sclerosis (MS). The aim of this study was to investigate the serum levels of vitamin D, vitamin D binding protein (VDBP) and vitamin D receptors (VDR) and to evaluate cardiac dysautonomia in MS patients due to bidirectional interaction between vitamin D and the autonomic nervous system. Methods: The current cross-sectional study was conducted on 26 patients with relapsing-remitting MS and on 24 healthy controls. Twenty-four-hour ambulatory blood pressure variability (BPV) was calculated and the participants were evaluated for orthostatic hypotension and supine hypertension. Serum levels of vitamin D, VDBP and VDR were measured. Results: The mean serum vitamin D level was significantly lower in MS patients than in controls (p = 0.044); however there was no significant difference in terms of VDR and VDBP levels between the groups. Supine hypertension and orthostatic hypotension were significant and the 24-hour systolic BPV was significantly decreased in patients with MS (p < 0.05) compared to controls. No correlation was found between vitamin D, VDBP and VDR with supine hypertension, orthostatic hypotension and systolic BPV values (p > 0.05). Also, there was a negative correlation between VDBP and the EDSS (p = 0.039, r = −0.406). Conclusion: There was no correlation between orthostatic hypotension, supine hypertension and systolic BPV values and serum vitamin D, VDBP and VDR in MS patients. Future prospective studies with large number of patients may help us to better understand the relationship between vitamin D and the autonomic nervous system.

RESUMO A vitamina D é um hormônio esteroide pleiotrópico que modula o equilíbrio autonômico. Sua deficiência tem sido descrita como fator de risco ambiental para esclerose múltipla (EM). O objetivo deste estudo foi investigar os níveis séricos de vitamina D, proteína de ligação à vitamina D (VDBP) e receptor de vitamina D (VDR) e avaliar a disautonomia cardíaca em pacientes com EM devida à interação bidirecional entre vitamina D e sistema nervoso autônomo. Métodos: O presente estudo transversal foi realizado em 26 pacientes com EM remitente-recorrente e em 24 controles saudáveis. A variabilidade da pressão arterial ambulatorial (BPV) por 24 horas foi calculada e os participantes foram avaliados quanto à hipotensão ortostática e hipertensão supina. Os níveis séricos de vitamina D, VDBP e VDR foram medidos. Resultados: O nível sérico médio de vitamina D foi significativamente menor nos pacientes com EM do que nos controles (p = 0,044); no entanto, não houve diferença significativa em termos de níveis de VDR e VDBP entre os grupos. Hipertensão supina e hipotensão ortostática foram significativas e a BPV sistólica de 24 horas diminuiu significativamente em pacientes com EM (p < 0,05) em comparação aos controles. Não foi encontrada correlação entre vitamina D, VDBP e VDR com hipertensão supina, hipotensão ortostática e BPV sistólica (p > 0,05). Também houve correlação negativa entre VDBP e EDSS (p = 0,039, r = −0,406). Conclusão: Não houve correlação entre hipotensão ortostática, hipertensão supina e valores de BPV sistólica e vitamina D sérica, VDBP e VDR em pacientes com EM. Futuros estudos prospectivos com grande número de pacientes podem nos ajudar a entender melhor a relação entre vitamina D e sistema nervoso autônomo.

Aortic Stiffness Index And Carotid Intima-Media Thickness Are Independently Associated With The Presence Of Microalbuminuria In Patients With Type 2 Diabetes Mellitus.

PURPOSE: Microalbuminuria is a premature and widely used indicator of diabetic nephropathy and is reported to be related with a higher cardiovascular risk in diabetic patients. We aimed to examine whether the echocardiographic parameters, such as epicardial fat thickness (EFT), carotid intima-media thickness (CIMT) and aortic stiffness index (ASI) are associated with microalbuminuria in patients with diabetes mellitus type 2 (T2DM). PATIENTS AND METHODS: A total of 272 consecutive patients were enrolled and after the exclusion criteria, the data of 180 patients with T2DM were used in this cross-sectional study. Patients were divided into two groups: 82 patients with microalbuminuria and 98 patients without microalbuminuria (normoalbuminuria). The laboratory results and echocardiographic EFT, CIMT and ASI parameters were noted. RESULTS: Compared with the normoalbuminuria group, EFT, CIMT and ASI were significantly higher in the microalbuminuria group (p<0.05 for all). In logistic regression analysis; CIMT (OR: 3.15, p=0.024) and ASI (OR: 4.19, p=0.016) were independently associated with microalbuminuria in patients with T2DM. CONCLUSION: In addition to CIMT, as a novel finding, ASI which is an indicator for the elastic properties of the aortic root was independently associated with microalbuminuria. CIMT and ASI measurement by echocardiography may be helpful in identifying the accompanying factors in the development of nephropathy.

The association between high-grade varicocele and endothelial dysfunction.

Varicocele is determined as dilatation of veins in the pampiniform plexus of the spermatic cord. Although various factors have been implicated in the pathophysiology of varicocele, the underlying aetiological cause is not fully understood. Endothelial dysfunction is a precursor of vascular pathologies that may develop gradually and a substantial inducer in atherosclerosis aetiology. Brachial artery flow-mediated dilatation (FMD) measurement with sensitive brachial artery ultrasonography for assessing endothelial function is the most common noninvasive method. Similarly, carotid intima-media thickness (CIMT), measured using noninvasive ultrasonographic methods, is a tool for evaluating subclinical atherosclerosis and gives information on early changes in the vessel wall structure. Totally, 128 patients met the criteria were evaluated in this study. FMD was significantly lower in the varicocele group compared with the control group (9.16 ± 3.34 vs.7.96 ± 1.88, p = .013). CIMT measurements were similar between the groups (p = .091). Multivariate logistic regression revealed that FMD was independently associated with varicocele [odds ratio (OR): 0.814; 95% confidence interval (CI): 0.697-0.950; p = .009]. We suggest that endothelial dysfunction may have a role in the varicocele. Therefore, we recommend that every patient with symptomatic varicocele should be evaluated and followed up regularly for cardiovascular pathologies.

Relationship of serum calprotectin, angiopoietin­1, and angiopoietin­2 levels with coronary collateral circulation in patients with stable coronary artery disease.

BACKGROUND: In patients with chronic stable coronary artery disease (CAD), well­developed coronary collateral circulation (CCC) is known to reduce long­term mortality. AIMS: The objective of this study was to determine the relationship of serum calprotectin (S100A8 / S100A9), angiopoietin­1 (Ang­1) and angiopoietin­2 (Ang­2) concentrations with CCC in patients with stable CAD. METHODS: This prospective cross­sectional study included 147 patients with stable angina pectoris. The Cohen-Rentrop classification was used to assess CCC. Patients were divided into 2 groups: with poor CCC (Cohen-Rentrop score, 0-1; n = 79) and with good CCC (Cohen-Rentrop score, 2-3; n = 68). Serum calprotectin, Ang­1, and Ang­2 concentrations were compated between groups. RESULTS: Compared with the group with good CCC, serum calprotectin and Ang­1 levels were higher (P <0.01 and P <0.001, respectively), while serum Ang­2 levels were lower (P <0.01) in the poor­CCC group. C­reactive protein levels showed a moderate positive correlation with calprotectin levels (r = 0.359; P <0.001). In a multivariate regression analysis, only calprotectin (P <0.05) and Ang­1 (P <0.05) were found to be independent predictors of good and poor CCC. CONCLUSIONS: Our study showed that Ang­2 levels were lower, while serum calprotectin and Ang­1 levels were higher, in patients with stable CAD and poor CCC regardless of the complexity and severity of coronary arteriosclerosis. If these results are confirmed in future studies, calprotectin may be considered a useful biomarker for guiding anti­ischemic treatment.

Evaluation of Tp-e interval, Tp-e/QT ratio, and Tp-e/QTc ratio in patients with Behçet's disease.

OBJECTIVE: Behçet's disease (BD), a multisystemic inflammatory disorder, has been associated with a number of cardiovascular dysfunctions, including ventricular arrhythmias and sudden cardiac death. The mechanism of increased ventricular arrhythmias in BD remains uncertain. The aim of the present study was to assess the ventricular repolarization by using the Tp-e interval, Tp-e/QT ratio, and Tp-e/QTc ratio as candidate markers of ventricular arrhythmias in patients with BD. METHODS: A total of 42 patients (mean age: 42.71±10.99 years) with BD and 50 sex- and age-matched healthy volunteers (mean age: 39.24±11.32 years) as the control group were evaluated. The risk of ventricular arrhythmia was evaluated by calculating the electrocardiographic, the Tp-e interval, and the QT, QTc, Tp e/QT, and Tp-e/QTc ratios. RESULTS: QTmax (p=0.005), QTcmax (p=0.015), QTmin (p=0.011), and QTcmin (p=0.024) were statistically significantly higher in the BD group than in the control group. The Tp-e, cTp-e, Tp-e/QT, and Tp-e/QTc ratios were also significantly higher in patients with BD than in the control group (80.26±4.55 and 74.74±6.47, respectively, p<0.001; 88.23±6.36 and 82.68±7.81, respectively, p<0.001; 0.21±0.01 and 0.20±0.01, respectively, p=0.008; and 0.19±0.01 and 0.18±0.01, respectively, p=0.01). Positive correlations were found between Tp-e/QTc ratio and disease duration (r=0.382, p=0.013). CONCLUSION: Our study showed that the Tp-e interval, Tp-e/QT ratio, and Tp-e/QTc ratio, which are evaluated electrocardiographically in patients with BD, have been prolonged compared with normal healthy individuals. A positive correlation was determined between disease duration and Tp-e/QTc ratio. These results may be indicative of an early subclinical cardiac involvement in patients with BD, considering the duration of the disease. Therefore, these patients should be more closely screened for ventricular arrhythmias.

Correlation of Resting Heart Rate with the Severity and Complexity of Coronary Artery Disease: A Single-Center Retrospective Study.

BACKGROUND: We aimed to explore the association between resting heart rate (RHR) and the severity and complexity of atherosclerosis in coronary artery disease (CAD). METHODS: Clinical and laboratory data of 388 patients who underwent coronary angiography were evaluated retrospectively. SYNTAX and Gensini scores were calculated based on angiographic findings. These scores which indicate the severity of atherosclerosis was calculated for all the patients. Patients were divided into three main groups according to RHR. Group 1 composed of patients with RHR ≤70 (n = 217), group 2 composed of patients with RHR between 70 and 89 (n = 133), and group 3 composed of patients with RHR ≥90 beats per min (bpm) (n = 38). Gensini and SYNTAX score values of the three study groups were compared. Also, Gensini score was tested for whether it showed a positive correlation with RHR and SYNTAX scores. RESULTS: All patients had an average age of 61.3 years, and the mean for RHR was 72 bpm. Mean Gensini score in the general CAD population was 24.4 ± 22.5, and mean SYNTAX score was 13.6 ± 8.1 points. The Gensini and Syntax score values of the group 3 were significantly higher than that of the other two groups (59.8 ± 31.2, P < 0.001 and 26.0 ± 6.5, P < 0.001, respectively). There was a significant correlation with Gensini score and RHR, SYNTAX score, C-reactive protein (CRP), and left ventricular ejection fraction [(r = 0.725, P < 0.001), (r = 0.680, P < 0.001), (r = 0.543, P < 0.001), (r = -0.224, P < 0.001), respectively]. CONCLUSIONS: RHR is an effective easily available marker for the assessment of severity and complexity of CAD.

Electrocardiographic changes in right ventricular metastatic cardiac tumor mimicking acute ST elevation myocardial infarction: A case of misdiagnosis.

INTRODUCTION: In patients with ST elevation myocardial infarction (STEMI), minimizing the reperfusion time is the goal of therapy worldwide. However, the differential diagnosis is critical and when a patient is encountered with chest pain and ST elevation, STEMI should not be the only diagnosis considered. By detailed history and focused physical examination, it is possible to avoid a mistaken diagnosis. CASE PRESENTATION: In this report, we present a case of a male patient with tongue cancer and accompanying myocardial metastasis that causes electrocardiographic changes, who was initially misdiagnosed with ST elevation myocardial infarction. CONCLUSION: Here, we reported a case of metastatic cancer in the heart which was initially diagnosed as acute myocardial infarction. Echocardiography, computed tomography and magnetic resonance imaging of the heart were used accordingly to confirm the myocardial metastasis.

Vitamin D, vitamin D binding protein, vitamin D receptor levels and cardiac dysautonomia in patients with multiple sclerosis: a cross-sectional study.

OBJECTIVES: Vitamin D is a pleiotropic steroid hormone that modulates the autonomic balance. Its deficiency has been described as an environmental risk factor for multiple sclerosis (MS). The aim of this study was to investigate the serum levels of vitamin D, vitamin D binding protein (VDBP) and vitamin D receptors (VDR) and to evaluate cardiac dysautonomia in MS patients due to bidirectional interaction between vitamin D and the autonomic nervous system. METHODS: The current cross-sectional study was conducted on 26 patients with relapsing-remitting MS and on 24 healthy controls. Twenty-four-hour ambulatory blood pressure variability (BPV) was calculated and the participants were evaluated for orthostatic hypotension and supine hypertension. Serum levels of vitamin D, VDBP and VDR were measured. RESULTS: The mean serum vitamin D level was significantly lower in MS patients than in controls (p = 0.044); however there was no significant difference in terms of VDR and VDBP levels between the groups. Supine hypertension and orthostatic hypotension were significant and the 24-hour systolic BPV was significantly decreased in patients with MS (p < 0.05) compared to controls. No correlation was found between vitamin D, VDBP and VDR with supine hypertension, orthostatic hypotension and systolic BPV values (p > 0.05). Also, there was a negative correlation between VDBP and the EDSS (p = 0.039, r = -0.406). CONCLUSION: There was no correlation between orthostatic hypotension, supine hypertension and systolic BPV values and serum vitamin D, VDBP and VDR in MS patients. Future prospective studies with large number of patients may help us to better understand the relationship between vitamin D and the autonomic nervous system.
