RESUMO
Ramadan interferes with circadian rhythms mainly by disturbing the routine patterns of feeding and smoking. The objective of this study was to investigate the circadian pattern of ST elevation acute myocardial infarction (STEMI) during the month of Ramadan. We studied consecutive STEMI patients 1 month before and after Ramadan (non-Ramadan group-NRG) and during Ramadan (Ramadan group-RG). The RG group was also divided into two groups, based on whether they chose to fast: fasting (FG) and non-fasting group (NFG). The time of STEMI onset was compared. A total of 742 consecutive STEMI patients were classified into 4 groups by 6 h intervals according to time-of-day at symptom onset. No consistent circadian variation in the onset of STEMI was observed both between the RG (P = .938) and NRG (P = .766) or between the FG (P = .232) and NFG (P = .523). When analyzed for subgroups of the study sample, neither smoking nor diabetes showed circadian rhythm. There was a trend towards a delay from symptom onset to hospital presentation, particularly at evening hours in the RG compared with the control group. In conclusion, there was no significant difference in STEMI onset time, but the time from symptom onset to hospital admission was significantly delayed during Ramadan.

BACKGROUND: 25-hydroxy vitamin D (25OHD) deficiency is associated with cardiovascular disease and poor physical performance. OBJECTIVE: To assign the effect of 25OHD level on cardiac rehabilitation (CR) in patients with coronary artery disease (CAD). METHODS: One-hundred-thirty-five patients with CAD who underwent a CR programme were enrolled in this retrospective study. Patients were divided into two-group according to 25OHD level (Group 1: < 20 ng/dl; Group 2: ⩾ 20 ng/dl). All patients received CR for 30 sessions. Each participant performed 40 minutes of aerobic exercise with a cycloergometer followed by muscle strengthening exercises. The patients were evaluated before and after CR by a pulmonary function test (PFT) and a cardiopulmonary exercise test (CPET). RESULTS: There were 77 (57%) patients in Group 1 and 58 patients (43%) in Group 2. Demographic characteristics between the groups were similar. Pre- and post-rehabilitation CPET parameters were lower in Group 1 (p< 0.05). Both groups had significant improvement in CPET (p< 0.05). Post-rehabilitation PFT parameters (FEV1, FVC) were higher in Group 2 (p< 0.05). There was a positive correlation between the 25OHD-level and the CPET-PFT parameters (p< 0.05). CONCLUSION: 25OHD deficiency in patients with CAD reduces the response to CR. It also affects respiratory function according to the FEV1, FVC parameters. In patients scheduled for CR, 25OHD-levels should be evaluated, and any deficiency corrected.

BACKGROUND: The Appropriateness of Aspirin Use in Medical Outpatients: A Multicenter, Observational Study trial has been the largest study ever conducted among patients in Turkey regarding aspirin treatment. In the subgroup analysis of the hypertensive group of the Appropriateness of Aspirin Use in Medical Outpatients: A Multicenter, Observational Study trial, we aimed to evaluate the physicians' adherence to current guidelines regarding their aspirin treatment preferences. METHODS: The Appropriateness of Aspirin Use in Medical Outpatients: A Multicenter, Observational Study trial is a cross-sectional and multicenter study conducted among 5007 consecutive patients aged ≥18 years. The study population consisted of outpatients on aspirin treatment (80-300 mg). The patient data were obtained from 30 different cardiology clinics of 14 cities from all over Turkey. In this subgroup analysis, patients were divided into 2 groups: the hypertensive group (n=3467, 69.3%) and the group without hypertension (n=1540, 30.7%) according to the 2018 European Society of Cardiology/ European Society of Hypertension Guidelines for the Management of Arterial Hypertension. RESULTS: Aspirin use for primary prevention was higher in patients with hypertension compared to patients without hypertension [328 (21.3%); 1046 (30.2%); P < .001]. Treatment with a dose of 150 mg aspirin (n=172, 5%) was mostly preferred by internists for hypertensive patients (n =226, 6.5%); however, a daily dose of 80-100 mg aspirin therapy (n=1457, 94.6%) was mostly prescribed by cardiologists (n=1347, 87.5%) for patients without hypertension. CONCLUSION: Aspirin was found to be used commonly among patients with hypertension for primary prevention despite the current European Society of Cardiology Arterial Hypertension Guideline not recommending aspirin for primary prevention in patients with hypertension.

BACKGROUND: Indications and appropriateness of aspirin use have not been well investigated in Turkey. AIMS: To investigate the prescription patterns and appropriateness of aspirin in a real-world clinical setting. STUDY DESIGN: Cross-sectional study. METHODS: The Appropriateness of Aspirin Use in Medical Outpatients: A Multicenter, Observational Study (ASSOS) is a cross-sectional and multicenter study that included 5007 consecutive patients aged 18 or over who presented to 30 different cardiology outpatient clinics from 14 cities throughout Turkey. Only patients using aspirin (80-325 mg) were included. The study population was divided into 2 groups regarding the use of aspirin: primary prevention (PP) group and secondary prevention (SP) group. The indication of aspirin use was evaluated following the 2016 European Society of Cardiology (ESC) and the 2016 United States Preventative Services Task Force (USPTF) guidelines in the PP group. RESULTS: A total of 5007 patients (mean age 62.15 ± 11.05, 39% female) were enrolled. The PP group included 1132 (22.6%) patients, and the SP group included 3875 (77.4%) patients. Of the 1132 patients, inappropriate use of aspirin was determined in 100% of the patients according to the ESC guidelines, and 71% of the patients according to the USPTF guidelines. Multivariate logistic regression analysis showed age OR: 0.98 CI (0.97-0.99) P = .037, smoking OR: 0.60 CI (0.44-0.82) P = .001, heart failure OR: 2.11 CI (1.14-3.92) P = .017, hypertension OR: 0.51 CI (0.36-0.74) P < .001, diabetes mellitus OR: 0.34 CI (0.25-0.47) P < .001, oral anticoagulant use OR: 3.01 CI (1.10-8.25) P = .032, and female sex OR: 2.73 CI (1.96-3.80) P < .001 were independent predictors of inappropriate aspirin use in PP patients. CONCLUSION: Although there are considerable differences between the USPTF and the ESC guidelines with respect to recommendations for aspirin use in PP, inappropriate use of aspirin in Turkey is frequent in real-world practice for both guidelines. Besides, heart failure, oral anticoagulant use, and the female sex of the patients were independent predictors of inappropriate use of aspirin.

OBJECTIVE: Epicardial adipose tissue (EAT) is a cardiometabolic risk factor, and its possible relationship with hypertension has been previously reported. Microalbuminuria (MA) is associated with target-organ damage, especially in patients with hypertension with left ventricular hypertrophy (LVH) and suggest endothelial dysfunction. This study aimed to investigate the relationship between echocardiographic EAT thickness and presence of MA in patients with hypertension. METHODS: A total of 297 newly diagnosed hypertension patients who applied to the outpatient clinic were enrolled consecutively in this study. Patients were divided into two groups regarding the presence of LVH in echocardiography. An age and gender matched control group was set including 156 healthy patients without HT. All subjects underwent transthoracic echocardiography for the measurement of EAT thickness. Spot urine samples were collected for the assessment of MA. RESULTS: In hypertensive patients with LVH, the EAT thicknesses (6.6 ± 1.8 vs 5.3 ± 1.5 vs 5.1 ± 1.3, p < .001; respectively) and prevalence of MA (41.2 vs 20.1 vs 3.2%; p < .001 respectively) were significantly higher than the other two groups. In hypertensive patiens without LVH, no relationship was found between the presence of MA and EAT thickness. In multivariate regression analyses, EAT thickness (OR: 3.141, 95%CI: 2.425-6.123, p < .001) and left ventricular mass index (OR: 1.339, 95%CI: 1.145-2.143, p = .003) were determined as independent predictors for MA development in hypertensive patients with LVH. CONCLUSION: Measurement of EAT thickness may help to identify high-risk hypertensive patients for target-organ damage especially among patients with LVH.

BACKGROUND: Interatrial block (IAB), defined as a conduction delay between the right and left atrium, is manifested on the electrocardiogram as a prolonged P-wave duration. Large number of studies recently have been published regarding the prevalence of IAB and its associations with the risk of atrial fibrillation and ischemic stroke. Cardiovascular diseases are the leading causes of mortality in chronic kidney disease (CKD). In this study, we aimed to investigate echocardiographic predictors of IAB in patients with severe CKD. METHODS: This study enrolled a total of 155 patients [male: 95 (61.3%), mean age: 56.3 ± 12.8 years] with severe CKD (glomerular filtration rate < 30 mL/min). All patients were evaluated by electrocardiography and transthoracic echocardiography. IAB was defined as P wave duration of ≥ 120 ms on electrocardiography. RESULTS: Electrocardiography revealed IAB in 54 patients. The baseline demographic characteristics of the patients were similar in both groups with and without IAB. Left atrial diameter (LAD), left ventricular end-systolic and end-diastolic diameters, interventricular septal thickness, posterior wall thickness, left ventricular mass, left ventricular mass index (LVMI), and the prevalence of left ventricular hypertrophy were found to be significantly increased in patients with IAB. Increased LAD (OR = 1.119; 95% CI 1.019-1.228; p = 0.019) and LVMI (OR = 1.036; 95% CI 1.003-1.070; p = 0.031) were found to be independent predictors of IAB. CONCLUSION: A significant association exists between the presence of IAB and echocardiographic parameters related to left ventricular hypertrophy and left atrial dilatation. Presence of IAB may be an additional and easy diagnostic marker for risk stratification of patients with severe CKD.

Objective: Fragmented QRS (fQRS) detected on a 12-lead electrocardiogram (ECG) has been demonstrated to be a marker of myocardial fibrosis. Intercellular adhesion molecule-1 (ICAM-1) is a protein which plays an important role in fibro-inflammatory processes. In this study, we aimed to investigate the relationship between ICAM-1 levels and the presence of fQRS in hypertensive patients.Methods: Ninety consecutive patients who were diagnosed with hypertension were included in the study. ECG and transthoracic echocardiography were performed to all patients. fQRS was defined as additional R' wave or notching/splitting of S wave in two contiguous ECG leads. Serum ICAM-1 levels were measured using the enzyme-linked immunosorbent assay method. Patients were divided into two groups according to the presence of fQRS.Results: A total of 90 patients (female, 65%; mean age: 54.6 ± 8.5 years) were included in the study. fQRS was detected on ECG recordings of 47 (52.2%) patients. The demographic characteristics were similar between the groups. Left atrial diameter (p = .003), interventricular septal thickness (p = .013), posterior wall thickness (p = .01), left ventricular mass (p = .002), left ventricular mass index (p < .001), left ventricular hypertrophy (p = .001), and ICAM-1 levels (p < .001) were found to be significantly increased in fQRS(+) group. In multivariate analysis, only high ICAM-1 level was observed to be an independent predictor for the presence of fQRS (odds ratio: 1.029; 95%Confidence Interval: 1.013-1.045, p < .001).Conclusion: A significant association exists between serum ICAM-1 levels and the presence of fQRS in hypertensive patients. The presence of fQRS may be used as an indicator of inflammation in hypertensive patients.

PURPOSE: Cardiovascular complications have been reported to be the main cause of mortality in patients with end-stage renal disease (ESRD). Although left ventricular hypertrophy is the most common clinical presentation of cardiac remodeling, cardiovascular complications may also include disturbances of the heart conduction system. The R wave peak time (RWPT) has been previously associated with left ventricular hypertrophy and myocardial ischemia. In this study, we aimed to investigate the relationship between RWPT and echocardiographic parameters in patients with ESRD. METHODS: This study enrolled 66 patients (29 females, age 57.2 ± 12.8 years) with ESRD, and 72 controls (37 females, age 55.3 ± 10.1 years) with similar risk factors. All patients underwent electrocardiography and transthoracic echocardiography. The RWPT was defined as the interval between the onset of the QRS complex and the peak of the R or R' wave. RESULTS: There was no significant difference in terms of clinical and demographic parameters between ESRD patients and controls. Left ventricular ejection fraction was similar between the groups. However, left atrial diameter, interventricular septal thickness, posterior wall thickness, left ventricular mass (LVM) and left ventricular mass index (LVMI) were significantly higher in patients with ESRD. Among electrocardiographic parameters, P wave and QRS complex durations and RWPT were significantly higher in patients with ESRD. Prolonged RWPT, increased LVM and LVMI were identified as associates of ESRD. Furthermore, RWPT correlated well with LVM and LVMI. CONCLUSION: The present study demonstrated that RWPT prolonged significantly in patients with ESRD. Furthermore, prolonged RWPT has been associated with increased LVM and LVMI.

BACKGROUND: Ventricular arrhythmias (VAs) are frequent in hypertensive patients. Myocardial fibrosis is one of the components of left ventricular hypertrophy secondary to hypertension. Fragmented QRS (fQRS) on electrocardiography (ECG) has been shown to be a marker of myocardial fibrosis. In this study, we aimed to investigate the association between fQRS and complex VAs in patients with essential hypertension. METHODS: Two hundreds consecutive patients who were diagnosed with hypertension were included in the study. The control group consisted of 153 age and sex matched healthy individuals. ECG and transthoracic echocardiography were performed to all patients. fQRS was defined as additional R' wave or notching/splitting of S wave in two contiguous ECG leads. All patients underwent 24-hour Holter monitoring and VAs were classified using Lown's scoring system. Lown class ≥3 VAs were considered as complex VAs. RESULTS: There was no significant difference with respect to age (52⯱â¯8 vs 52⯱â¯6 years, pâ¯=â¯0.836) and gender distribution (female: 64% vs 63%, pâ¯=â¯0.907) between the groups. As compared to the healthy individuals, prevalence of fQRS (67% vs 9.2%, pâ¯<â¯0.001) and complex VAs (19% vs 0%, pâ¯<â¯0.001) were significantly higher in patients with hypertension. Furthermore, complex VAs (25.4% vs 6.1%, pâ¯=â¯0.001) were significantly higher in hypertensive patients with fQRS. In multiple logistic regression analysis, left ventricular ejection fraction (OR: 1.11, 95%CI: 1.025 to 1.183; pâ¯=â¯0.006), left ventricular mass index (OR: 1.04, 95%CI: 1.021 to 1.107; pâ¯=â¯0.001) and presence of fQRS (OR: 5.605, 95%CI: 1.427 to 22.019; pâ¯=â¯0.014) were independent predictors for complex VAs. CONCLUSION: The presence of fQRS may be associated with complex VAs in patients with essential hypertension. Therefore, fQRS may be used in risk stratification of complex VAs and sudden cardiac death especially in hypertensive patients with left ventricular hypertrophy.

BACKGROUND: Epicardial adipose tissue (EAT) is a cardiometabolic risk factor, and its possible relationship with hypertension has been reported previously. Fragmented QRS (fQRS) detected on electrocardiography (ECG) has been demonstrated to be a marker of myocardial fibrosis. In this study, we aimed to investigate the relationship between the thickness of EAT, and presence of fQRS in hypertensive patients. METHODS: Consecutive patients who were diagnosed with hypertension were included in the study. ECG and transthoracic echocardiography (TTE) were performed to all patients. fQRS was defined as additional R' wave or notching/splitting of S wave in two contiguous ECG leads. Thickness of EAT was measured by TTE. RESULTS: This study enrolled 69 hypertensive patients with fQRS on ECG and 45 hypertensive patients without fQRS as the control group. Age (P = .869), and gender distribution (P = .751) were similar in both groups. Left atrial diameter (P = .012), interventricular septal thickness (P < .001), posterior wall thickness (P < .001), left ventricular ejection fraction (P = .009), left ventricular mass (P = .006), left ventricular mass index (P = .014), left ventricular hypertrophy (P = .003), and EAT thickness (P < .001) were found to be significantly increased in patients with fQRS. In multivariate analysis, among these variables only EAT was observed to be an independent predictor of fQRS (odds ratio:3.306 [95% confidence interval, 0.030-0.118], P = .001). CONCLUSION: A significant association exists between the presence of fQRS and EAT thickness in hypertensive patients. The presence of fQRS, just as EAT thickness, may be used as a cardiometabolic risk factor in hypertensive patients.

BACKGROUND: Current evidence indicates that vascular calcification plays an essential role in the development of cardiovascular diseases in end-stage renal disease (ESRD) patients. Arterial stiffness is a marker of increased cardiovascular risk in various populations. The aim of this study is to evaluate the elastic properties of ascending aorta in patients with ESRD. METHODS: This single-center study enrolled 96 patients (45 females, age: 57.2 ± 12.8 years) with ESRD and 96 healthy controls (52 females, age: 55.3 ± 10.1 years). Aortic pressures and aortic elastic parameters including aortic strain, aortic distensibility, aortic stiffness index, and aortic compliance were calculated using accepted formulae. RESULTS: The hemodynamic parameters including aortic pulse pressure, aortic mean pressure, aortic fractional pulse pressure, and aortic pulsatility index were significantly higher in patients with ESRD. Systolic and diastolic aortic diameters were similar between the groups. However, pulsatile aortic diameter change, aortic strain, aortic distensibility, and aortic compliance were significantly lower, whereas aortic stiffness index was significantly higher in ESRD group. CONCLUSIONS: The results demonstrated that a significant difference was present in terms of aortic blood pressures between patients with ESRD and controls. In addition, the elastic properties of ascending aorta were decreased in patients with ESRD.
RESUMO
BACKGROUND: Previous studies have demonstrated that homocysteine and asymmetric dimethyl arginine (ADMA) levels were strongly associated with cardiovascular diseases including coronary artery disease. The aim of this study was to investigate the role of plasma homocysteine and ADMA levels in the pathogenesis of coronary slow flow (CSF) phenomenon. METHODS: Twenty-three patients with CSF and 25 controls with normal coronary flow were included in this study. The quantitative measurement of coronary blood flow was performed using the thrombolysis in myocardial infarction frame count method. Plasma homocysteine and ADMA levels were determined using enzymatic assays from venous blood samples. RESULTS: The patients with CSF had significantly higher plasma homocysteine levels than controls (16.2 ± 7.6 vs. 12.2 ± 2.2 µM/L; p = 0.023). The uric acid levels were significantly higher in CSF group than controls (5.4 ± 1.1 vs. 4.6 ± 0.9 mg/dl; p = 0.011). Plasma ADMA levels were also higher in the CSF group; however, this was not statistically significant (0.6 ± 0.1 vs. 0.5 ± 0.2 µM/L; p = 0.475). CONCLUSIONS: Increased homocysteine and uric acid levels may play an important role in the pathogenesis of CSF. Further large scale studies are required to determine the relationship between ADMA levels and CSF.
RESUMO
INTRODUCTION: Impaired coronary microcirculation, inflammation, and endothelial dysfunction were reported etiological factors for microvascular angina (MVA). Recently, increased epicardial adipose tissue (EAT) thickness has been associated with hypertension, metabolic syndrome, and coronary artery disease in general population. In this study, we aimed to evaluate the EAT thickness in patients with MVA. METHODS: This study enrolled 200 patients (83 males; mean age: 55.4 ± 8.2 years) who have been diagnosed with MVA and 200 controls (89 males; mean age: 54.4 ± 8.5 years). All patients underwent transthoracic echocardiography, and EAT thickness was measured from a parasternal long-axis view as the hypoechoic space on the right ventricular free wall. RESULTS: The mean EAT thickness was significantly higher in MVA patients than the controls (5.5 ± 1.1 vs. 4.9 ± 0.7 mm; p < 0.001). Multiple logistic regression analysis showed that increased EAT thickness was an independent predictor of MVA (OR = 1.183, 95% CI = 1.063-1.489; p = 0.023). In receiver operating characteristic curve analyses, EAT thickness above 5.3 mm predicted MVA with a sentivity of 68% and a specificity of 63% (AUC = 0.711, 95% CI = 0.659-0.762; p < 0.001). CONCLUSIONS: The EAT thickness was observed significantly higher in MVA patients as compared to controls. Increased EAT thickness may be associated with mechanisms that play a major role in the pathogenesis of MVA.
RESUMO
OBJECTIVE: The aim of this study was to describe the current status of aspirin use and the demographic characteristics of patients on aspirin for primary and secondary prevention of cardiovascular diseases. METHODS: The Appropriateness of Aspirin Use in Medical Outpatients: A Multicenter, Observational Study (ASSOS) trial was a multicenter, cross-sectional, and observational study conducted in Turkey. The study was planned to include 5000 patients from 14 cities in Turkey. The data were collected at one visit, and the current clinical practice regarding aspirin use was evaluated (ClinicalTrials.gov number NCT03387384). RESULTS: The study enrolled all consecutive patients who were admitted to the outpatient cardiology clinics from March 2018 until June 2018. Patients should be at least 18 years old, have signed written informed consent, and on aspirin (80-325 mg) therapy within the last 30 days. Cardiologists from the hospital participates in the study. Patients were divided into 2 categories according to presence or absence of atherosclerotic cardiovascular disease, namely secondary prevention group and primary prevention group, respectively. The appropriate use of aspirin in the primary and secondary prevention groups was assessed according to the European Society of Cardiology guidelines and US Preventive Services Task Force. The patients' gastrointestinal bleeding risk factors and colorectal cancer risk were evaluated. CONCLUSION: The ASSOS registry will be the most comprehensive and largest study in Turkey evaluating the appropriateness of aspirin use. The results of this study help understand the potential misuse of aspirin in a real-world setting.

PURPOSE: Cardiovascular diseases are the leading causes of mortality in chronic kidney disease. Spondin-2 (SP-2), an intrinsic cardio-protective factor, prevents maladaptive remodeling. We aimed to determine the relation between serum SP-2 levels and cardiac morphology along with inflammatory parameters in hemodialysis (HD) patients. METHOD: The study comprised a total of 95 patients (61 females) receiving HD treatment three times a week for at least 6 months, and a control group consisting of age and gender matched 62 subjects (34 females). SP-2 levels were determined by ELISA. Echocardiography, 24-h ambulatory blood pressure monitoring, and carotid artery intima-media thickness (CIMT) measurement were performed in all subjects. The relation of serum SP-2 levels with CIMT, echocardiographic parameters, CRP, and absolute neutrophil-to-lymphocyte count ratio (NLR) was evaluated by correlation analysis. RESULTS: SP-2 levels were found to be significantly higher in the HD group than the control group (16.660 [8.719-20.938] vs. 3.988 [2.702-8.042] ng/L; P < 0.001). CIMT, CRP, and NLR were also higher in HD group (P < 0.005, P < 0.001, and P < 0.001, respectively). Significantly positive correlation was found between SP-2 and left ventricular mass, left ventricular mass index, CRP, and NLR, but no correlation was determined between SP-2 and CIMT. SP-2 was not statistically significant variable for the determination of LVH in univariate logistic regression analysis [Wald = 2.375; OR (95% CI) = 1.000 (0.999-1.000), P = 0.123]. CONCLUSION: Serum SP-2 levels were higher in HD patients compared to the population with normal renal functions. The results suggest that SP-2, an uremic toxin, might be effective over a complex pathway in the inflammatory process and in the pathogenesis of cardiovascular diseases of patients under HD treatment.

Cardiovascular diseases are the leading causes of mortality in patients with chronic kidney disease. Nitric oxide has a critical role in both endothelial dysfunction and the atherosclerosis process. We aimed to investigate the relationships between serum asymmetric dimethyl arginine (ADMA), LOX-1, and Apelin-13 levels, which are known to act over nitric oxide with endothelial dysfunction and cardiac morphology as well as with each other in hemodialysis patients. The study comprised a total of 120 patients (53 females and 67 males) receiving hemodialysis three times a week for at least 6 months and an age-gender matched control group (55 females and 58 males). Serum ADMA, LOX-1, and Apelin-13 levels were measured using the ELISA technique. Echocardiography, 24-h blood pressure monitoring by the Holter and carotid artery intima-media thickness (CIMT) measurement was performed on all of the included subjects. The associations between serum ADMA, LOX-1, and Apelin-13 levels with CIMT, echocardiographic parameters [left ventricular mass (LVM) and left ventricular mass index (LVMI)], and inflammatory markers [high sensitive C-reactive protein (hsCRP) and neutrophil lymphocyte ratio (NLR)] were evaluated by correlation analysis. Serum ADMA, Apelin-13, and LOX-1 levels were significantly higher in the hemodialysis group than the controls (P < 0.001, P < 0.001, and P < 0.001, respectively). CIMT, hsCRP, and NLR levels were also significantly higher in the hemodialysis group (P < 0.05, P < 0.001, P < 0.001, respectively). Significant correlations were observed among the serum ADMA, Apelin-13, and LOX-1 levels. Moreover, notably positive correlations were found between these three biochemical markers and LVM, LVMI, hsCRP, and CIMT. Serum ADMA, Apelin-13, and LOX-1 levels can be indicators not only for the inflammatory process but also for the pathogenesis of cardiovascular diseases in hemodialysis patients.

PURPOSE: Mindin was associated with diabetic nephropathy, podocyte injury, colitis, allergic asthma, liver ischaemia and reperpusion injury and ischaemic brain injury. On the other hand, it was reported as a protective factor against obesity, cardiac hypertrophy, fibrosis and remodelling. Fragmented QRS complexes (fQRS) are markers of altered ventricular depolarisation owing to a prior myocardial scar and fibrosis. In this study, we aimed to investigate mindin levels in hypertensive patients with left ventricular hypertrophy and fQRS on electrocardiography. METHODS: This observational case-control study enrolled 70 (36 female) hypertensive patients with fQRS and 38 (23 female) hypertensive control patients. All patients were evaluated by transthoracic echocardiography. Mindin levels were measured by the enzyme-linked immunosorbent assay (ELISA). Clinical, echocardiographic and laboratory data were compared between patient and control groups. RESULTS: There was no significant difference between patient and control groups in terms of clinical, echocardiographic and routine laboratory parameters. The mindin levels were significantly higher in the patient group than controls (11.3 (7.21-19.31) vs 4.15 (2.86-6.34); p < .001). Multiple logistic regression analyses defined increased mindin levels as an independent predictor for the presence of fQRS (Odds ratio: 1.733; p = .034). Mindin levels >6.74 predicted the presence of fQRS with a sensitifity of 84.3% and specificity of 79.9% on receiver operating characteristic (ROC) curve analysis (The area under the curve:0.889; Confidence Interval: 0.827-0.951; p < .001). CONCLUSION: Mindin expressin is upregulated in hypertensive patients with fQRS complexes. In contrary to previous studies, increased mindin levels may be associated with myocardial fibrosis.

Interrupted aorta is a very rare heart defect in which there is a gap between the ascending and the descending thoracic aorta. It is usually associated with other cardiac anomalies, including ventricular septal defect, ductus arteriosus, and truncus arteriosus. Severe cases present with serious complications such as hypertension, heart failure, or intracranial hemorrhage. Neurological complications are very rare form of presentation and commonly associated with intracranial aneurysms. We have reported a case of interrupted aorta who presented with transient ischemic attack due to thrombus formation in the interrupted segment of the aorta.

Coronary pseudoaneurysms (CPAs) are rare complications developed after percutaneous coronary interventions. They may cause stent thrombosis, distal embolization, and coronary rupture leading to cardiac tamponade. Therefore, high-risk CPA should be promptly treated after diagnosis. They can be managed with percutaneous or surgical intervention. Herein, we aimed to present a patient who developed CPA 3 weeks after percutaneous coronary intervention and successfully treated with percutaneous intervention using a covered stent.
