Abstract
BACKGROUND Hypertrophic cardiomyopathy is a common genetic heart disease and up to 40%-60% of patients have mutations in cardiac sarcomere protein genes. This genetic diagnosis study aimed to detect pathogenic or likely pathogenic sarcomeric and non-sarcomeric gene mutations and to confirm a final molecular diagnosis in patients diagnosed with hypertrophic cardiomyopathy. METHODS A total of 392 patients with hypertrophic cardiomyopathy were included in this nationwide multicenter study conducted at 23 centers across Türkiye. All samples were analyzed with a 17-gene hypertrophic cardiomyopathy panel using next-generation sequencing technology. The gene panel includes ACTC1, DES, FLNC, GLA, LAMP2, MYBPC3, MYH7, MYL2, MYL3, PLN, PRKAG2, PTPN11, TNNC1, TNNI3, TNNT2, TPM1, and TTR genes. RESULTS The next-generation sequencing panel identified positive genetic variants (variants of unknown significance, likely pathogenic or pathogenic) in 12 genes for 121 of 392 samples, including sarcomeric gene mutations in 30.4% (119/392) of samples tested, galactosidase alpha variants in 0.5% (2/392) of samples and TTR variant in 0.025% (1/392). The likely pathogenic or pathogenic variants identified in 69 (57.0%) of 121 positive samples yielded a confirmed molecular diagnosis. The diagnostic yield was 17.1% (15.8% for hypertrophic cardiomyopathy variants) for hypertrophic cardiomyopathy and hypertrophic cardiomyopathy phenocopies and 0.5% for Fabry disease. CONCLUSIONS Our study showed that the distribution of genetic mutations, the prevalence of Fabry disease, and TTR amyloidosis in the Turkish population diagnosed with hypertrophic cardiomyopathy were similar to the other populations, but the percentage of sarcomeric gene mutations was slightly lower.

Long-Term Prognosis of Patients with Heart Failure: Follow-Up Results of Journey HF-TR Study Population. Anatol J Cardiol 2023; 27:26-33. [PMID: 36680444 PMCID: PMC9893707 DOI: 10.14744/anatoljcardiol.2022.2171] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/27/2022] [Accepted: 10/21/2022] [Indexed: 01/21/2023] Open
Abstract
BACKGROUND Despite advances in therapeutic management of patients with heart failure, there is still an increasing morbidity and mortality all over the world. In this study, we aimed to present the 3-year follow-up outcomes of patients included in the Journey HF-TR study in 2016 that has evaluated the clinical characteristics and management of patients with acute heart failure admitted to the hospital and present a national registry data. METHODS The study was designed retrospectively between November 2016 and December 2019. Patient data included in the previously published Journey HF-TR study were used. Among 1606 patients, 1484 patients were included due to dropout of 122 patients due to inhospital death and due to exclusion of 173 due to incomplete data. The study included 1311 patients. Age, gender, concomitant chronic conditions, precipitating factors, New York Heart Association, and left ventricular ejection fraction factors were adjusted in the Cox regression analysis. RESULTS During the 3-year follow-up period, the ratio of hospitalization and mortality was 70.5% and 52.1%, respectively. Common causes of mortality were acute decompensation of heart failure and acute coronary syndrome. Angiotensin receptor blockers, betablockers, statin, and sacubitril/valsartan were found to reduce mortality. Hospitalization due to acute decompensated heart failure, acute coronary syndrome, lung diseases, oncological diseases, and cerebrovascular diseases was associated with the increased risk of mortality. Implantation of cardiac devices also reduced the mortality. CONCLUSIONS Despite advances in therapeutic management of patients with heart failure, our study demonstrated that the long-term mortality still is high. Much more efforts are needed to improve the inhospital and long-term survival of patients with chronic heart failure.

Abstract
OBJECTIVE While severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) primarily affects lung tissue, it may cause direct or indirect damage to the cardiovascular system, and permanent damage may occur. Arterial stiffness is an early indicator of cardiovascular disease risk. The aim of our study was to establish the potential effects of SARS-CoV-2 on the vascular system evaluated by transthoracic echocardiographic examination. SUBJECTS AND METHODS This study compared arterial stiffness between the survivors of COVID-19 and those without a history of COVID-19 infection. The difference in aortic diameter was examined using echocardiography. RESULTS The study included 50 patients who survived COVID-19 in the last 3-6 months and 50 age- and gender-matched healthy volunteers. In surviving COVID-19 patients, aortic diastolic diameter in cm ([3.1 ± 0.2] vs. [2.9 ± 0.1], p < 0.001), pulse pressure (PP) ([43.02 ± 14.05] vs. [35.74 ± 9.86], p = 0.004), aortic distensibility ([5.61 ± 3.57] vs. [8.31 ± 3.82], p < 0.001), aortic strain ([10.56 ± 4.91] vs. [13.88 ± 5.86], p = 0.003), PP/stroke volume index ([1.25 ± 0.47] vs. [0.98 ± 0.28], p = 0.001), and aortic stiffness index ([2.82 ± 0.47] vs. [2.46 ± 0.45], p < 0.001) were statistically significant compared to the control group. CONCLUSION SARS-CoV-2 may cause reduced or impaired aortic elasticity parameters linked to impaired arterial wall function in COVID-19 survivors compared with controls.

Abstract
OBJECTIVE In this study, we aimed to analyze the TURKMI registry to identify the factors associated with delays from symptom onset to treatment that would be the focus of improvement efforts in patients with acute myocardial infarction (AMI) in Turkey. METHODS The TURKMI study is a nation-wide registry that was conducted in 50 centers capable of 24/7 primary percutaneous coronary intervention (PCI). All consecutive patients (n=1930) with AMI admitted to coronary care units within 48 hours of symptom onset were prospectively enrolled during a predefined 2-week period between November 1, 2018, and November 16, 2018. All the patients were examined in detail with regard to the time elapsed at each step from symptom onset to initiation of treatment, including door-to-balloon time (D2B) and total ischemic time (TIT). RESULTS After excluding patients who suffered an AMI within the hospital (2.6%), the analysis was conducted for 1879 patients. Most of the patients (49.5%) arrived by self-transport, 11.8% by emergency medical service (EMS) ambulance, and 38.6% were transferred from another EMS without PCI capability. The median time delay from symptom-onset to EMS call was 52.5 (15-180) min and from EMS call to EMS arrival 15 (10-20) min. In ST-segment elevation myocardial infarction (STEMI), the median D2B time was 36.5 (25-63) min, and median TIT was 195 (115-330) min. TIT was significantly prolonged from 151 (90-285) min to 250 (165-372) min in patients transferred from non-PCI centers. The major significant factors associated with time delay were patient-related delay and the mode of hospital arrival, both in STEMI and non-STEMI. CONCLUSION The baseline evaluation of the TURKMI study revealed that an important proportion of patients presenting with AMI within 48 hours of symptom onset reach the PCI treatment center later than the time proposed in the guidelines, and the use of EMS for admission to hospital is extremely low in Turkey. Patient-related factors and the mode of hospital admission were the major factors associated with the time delay to treatment.

Abstract
The albumin to globulin ratio (AGR) is used as a prognostic marker in acute ischemic cardiovascular events. We investigated whether serum AGR, fibrinogen, and fibrinogen to albumin ratio (FAR) are related to the presence and severity of coronary artery disease (CAD). Patients who underwent coronary angiography procedures were analyzed retrospectively. The severity of CAD was assessed by the Gensini score. The study population (3031 patients; 1071 females and 1960 males) was divided into 3 tertiles based on AGR values. Gensini score, lipid levels, diabetes mellitus (DM), hypertension (HT), age, and fibrinogen level were higher in the low AGR group. Pearson correlation analysis showed that AGR (r = -0.068, P < .001) was negatively and fibrinogen (r = 0.187, P < .001) was positively correlated with the Gensini score. Male gender, HT, smoking, DM, age, high triglyceride (TG) level, low-density lipoprotein cholesterol (LDL-C) >160 mg/dL, estimated glomerular filtration rate (eGFR) <60 mL/min, and fibrinogen level >3.5 g/L were independent predictors of CAD. Male gender, age, eGFR, DM, LDL-C, TG, and FAR had an independent positive relation to the Gensini score. In conclusion, similar to traditional risk factors, plasma fibrinogen and albumin levels showed a close relation with the presence and severity of CAD.

Abstract
Peripheral artery disease affects nearly a quarter billion of the world's population, and it is one of the most important causes of decreased quality of life. Primary peripheral slow flow without significant stenosis in peripheral arteries has not been previously reported in the literature. In this case report, we present a slow flow phenomenon that extended from the right external iliac artery to the distal peripheral bed observed during peripheral angiography in a patient who exhibited pain and claudication in the right lower extremity after walking 50 m. Medical treatment provided symptomatic improvement in coronary slow flow and led to a decrease in claudication. Future randomised controlled studies conducted on patients with suspected peripheral slow flow phenomenon would increase our knowledge on both the aetiology and treatment of this condition.

Abstract
Objective: Impairment in left ventricular (LV) function due to excessive ventricular extrasystoles (VESs) occurs during long-time follow-up. Speckle tracking echocardiography (STE) has been shown to be superior to conventional methods for evaluating cardiac functions. We aimed to use STE for early detection of LV dysfunction in patients with apparently normal hearts who have frequent VESs. Methods: Fifty-five patients with frequent VESs were identified according to the Lown classification (Grade 2; unifocal more than 30 times in 1 h). Subjects aged 22-60 years with frequent VESs that had been detected for at least 1 year were included in the study according to the inclusion criteria. Forty-five subjects with similar demographic characteristics, but without VESs, were included as the control group. All participants were evaluated by STE. Results: Fifty-five patients with frequent VESs (mean age 47 years, range 22-60 years; 42.2% male) and 45 control subjects (mean age 46 years, range 22–60 years; 37.8% male) were enrolled in the study. Global LV longitudinal strain (GLS) was decreased in patients with frequent VESs (-18.41±3.37 and -21.82±2.43; p<0.001). In addition, global LV circumferential strain was decreased in patients with frequent VESs (-16.83±6.06, -20.51±6.02; p<0.001). The frequency and exposure time of VESs were negatively correlated with GLS (r=-0.398, p<0.001; r=-0.191, p=0.001, respectively). Conclusion: STE revealed that LV functions were decreased in patients with VESs. This deterioration increased with the frequency and exposure time of VESs. Impairment of LV function due to excessive VESs occurs during long-time follow-up. STE may be used for early detection of LV dysfunction.

Abstract
In this study, we have compared scintigraphic and echocardiographic data in order to investigate whether increased septal perfusion represents asymmetrical septal hypertrophy (ASH), which is a symptom followed in the scintigraphy of myocardial perfusion. The study consists of a total of 186 patients (120 females and 66 males with an average age of 59.45 ± 11.54 years) who had normal myocardial perfusion scintigraphy and echocardiography examinations. Statistical comparison of septal wall thickness measurements obtained from echocardiography and septal-to-lateral wall ratios (S/L ratio) was performed scintigraphically. Left ventricular mass values were obtained as both scintigraphic and echocardiographic data and their correlations were evaluated in order to assess the presence of left ventricular hypertrophy (LVH). In statistical analyses, the values of interventricular septal thickness in diastole (IVSd), left ventricle posterior wall thickness in diastole (LVPWd), left ventricle mass (LVM), and left ventricle mass index (LVMI) were found to be significantly higher in group 2 (S/L ratio >1) compared to group 1 (S/L ratio <1). In addition, S/L ratio is significantly correlated with echocardiographic IVSd, LVPWd, LVM, LVMI, and scintigraphic LVM (rest) values. Furthermore, echocardiographic LVM and LVMI values were significantly correlated with LVM and LVMI values obtained from scintigraphy. It should be known that increased S/L ratio that can be monitored during scintigraphic studies can be an indicator of septal hypertrophy and/or LVH, however, further examination and close follow-ups should be performed in necessary cases.

Abstract
Objective This study was designed to assess right ventricular systolic and diastolic function and its relationship with grade of hepatosteatosis (HS) in non-alcoholic fatty liver disease (NAFLD) patients using conventional and tissue Doppler echocardiography. Methods NAFLD was diagnosed in 32 individuals (15 males, 17 females; 59% were grade I HS, 41% grade II–III HS) by means of ultrasonography. Twenty-two individuals, whose ultrasonography data did not show HS, comprised the control group (11 males, 11 females) and were included in the study. Right ventricular systolic and diastolic function and their relationship with grade of HS were assessed by conventional and tissue Doppler echocardiography. Additionally, right ventricular global function was assessed by myocardial performance index (MPI). Results When compared by conventional echocardiographic parameters, there were no significant differences between the two groups. With tissue Doppler parameters, the tricuspid annulus peak early diastolic velocity and ratio of early-tolate diastolic velocity were lower in the patients than in the controls (p = 0.03, p = 0.02, respectively). The isovolumetric relaxation time and MPI were significantly higher (p < 0.001, p < 0.001, respectively) in the patient group. HS grade was positively correlated with right ventricular isovolumetric relaxation time and MPI index (r = 0.295, p = 0.03, r = 0.641, p < 0.001, respectively). Conclusion These results show that right ventricular diastolic dysfunction (RVDD) in patients with NAFLD and degree of HS was associated with RVDD.

Abstract
OBJECTIVES Patients with inflammatory bowel disease (IBD) have high cardiovascular morbidity, and, in general, epicardial adipose tissue thickness is related to atherosclerotic vascular disease. This study aimed to investigate the association between epicardial adipose tissue thickness and carotid intima-media thickness as markers of early atherosclerosis in patients with IBD. METHODS The study comprised 47 patients with IBD (25 with Crohn disease and 22 with ulcerative colitis) and 35 control participants. In all individuals, epicardial adipose tissue and carotid intima-media thickness values were measured by sonography. RESULTS The mean age ± SD of the 47 patients with IBD was 42.3 ± 11.2 years, versus 41.4 ± 10.1 years for the control group. The epicardial adipose tissue thickness was higher in both the Crohn disease and ulcerative colitis groups compared to the control group (P < .001), but not the carotid intima-media thickness (P = .695 and .917, respectively). There was a strong positive correlation between the carotid intima-media and epicardial adipose tissue thickness values in the Crohn disease and ulcerative colitis groups (r = 0.757; 95% confidence interval, 0.711-0.901; r = 0.786; 95% confidence interval, 0.364-0.615; both P < .001). However, there was no significant difference between the patients who were in the active and inactive disease periods in both groups in terms of carotid intima-media and epicardial adipose tissue thickness values. CONCLUSIONS Our findings suggest that epicardial adipose tissue thickness might be a marker for detection of early atherosclerosis in patients with IBD. There was a strong positive correlation between carotid intima-media thickness and epicardial adipose tissue thickness values in the patients with IBD. However, there was no correlation between IBD activity and carotid intima-media or epicardial adipose tissue thickness.

Abstract
Background Polycystic ovary syndrome (PCOS) is one of the most common endocrine disorders of women during the reproductive period. Cardiovascular risk factors are more frequent in patients with PCOS. We aimed to investigate the P-wave dispersion (Pd), inter- and intra-atrial conduction time and mechanical functions of the left atrium (LA) in patients with PCOS. Methods Forty-eight patients with PCOS and 38 normal healthy women were enrolled in this study. A 12-lead surface electrocardiogram was used to evaluate Pd. Left ventricular (LV) functions were measured using conventional and tissue Doppler imaging (TDI) methods. Inter- and intra-atrial conduction times were measured by TDI. LA volumes were measured echocardiographically with the biplane area–length method from the apical four-chamber view. Results Heart rate (82.02 ± 13.15 vs 74.24 ± 11.02 bpm, p = 0.014) and Pd were significantly increased in the PCOS patients [27 ± 5 vs 24 ± 6 ms, p = 0.035]. Transmitral E/A ratio was significantly lower in the PCOS patients than in the controls (1.5 ± 0.3 vs 1.7 ± 0.4 m/s, p = 0.023). Passive emptying volume (12.54 ± 4.39 vs 15.28 ± 3.85 ml/m2, p = 0.004) and passive emptying fraction [54.4 (21–69) vs 59.1% (28–74), p = 0.008] were significantly decreased in PCOS patients. Total emptying volume was significantly decreased (17.9 ± 5.49 vs 20.67 ± 4.29 ml/m2, p = 0.018) in PCOS patients. Interatrial (19 ± 7.4 vs 15 ± 6.4 ms, p = 0.035) and intra-atrial [8.5 (1–19) vs 5 ms (1–20), p = 0.026] electromechanical delays were found to be significantly higher in PCOS patients. Conclusion This study showed that patients with PCOS had increased inter- and intra-atrial conduction delays, and decreased LA passive emptying volumes and fractions.

Abstract
Recent studies have shown that there is a relationship between some inflammatory and biochemical markers derived from complete blood count (CBC) such as neutrophil/lymphocyte (N/L) ratio, platelet/lymphocyte (P/L) ratio, platelet distribution width (PDW), red blood cell distribution width (RDW), and coronary artery disease (CAD). The aim of this study was to determine N/L ratio, P/L ratio, PDW values, and RDW values, which are associated with myocardial perfusion in patients diagnosed with CAD. This study included 262 patients (149 with myocardial ischemia/infarction and 113 with normal myocardial perfusion) undergoing myocardial perfusion scintigraphy (MPS) with CBC within 90 days of MPS. Myocardial perfusion parameters such as summed stress score and summed difference score (SDS) were compared with N/L ratio, P/L ratio, PDW values, and RDW values. Neutrophil counts and N/L ratios were significantly higher in patients diagnosed with myocardial ischemia and/or infarct. However, there was no statistically significant relationship between myocardial perfusion abnormalities and P/L ratio, PDW values, and RDW values. This study showed that N/L ratio is related to myocardial ischemia/infarction and correlated to left ventricular ejection fraction (LVEF).

Abstract
Pregnancy-induced hypertension (PIHT) increases both maternal and neonatal mortality and morbidity in pregnant women. We sought to investigate the electrocardiographic findings in pregnant women with PIHT. Seventeen pregnant women (29.4 ± 5 years) with PIHT and 24 pregnant women (27.3 ± 6.1 years) with normal blood pressure (control group) were included in the study. A 12-lead surface electrocardiogram was used to evaluate the electrocardiographic parameters. Pregnant women with PIHT had higher blood pressure (p = 0.001). The Tp-e interval was longer in PIHT pregnant women at 83.5 ± 7.8 ms versus 75.8 ± 8.4 ms in the control group (p = 0.007). The Tp-e/QTc ratio was higher in pregnant women with PIHT than that in healthy controls (0.19 ± 0.02 vs. 0.18 ± 0.02, respectively). This study demonstrated that Pd, QTd and the P wave durations were similar in the PIHT pregnant women and control group, but the Tp-e and Tp-e/QTc ratio were higher in pregnant women with PIHT than in normotensive pregnant women.

Abstract
OBJECTIVE Paradoxical septal motion (PSM) can cause confusion in the assessment of ventricular function with scintigraphy even in the absence of ventricular septal damage and ischemia. Fragmented QRS (fQRS) is associated with various cardiac disorders. In this study, we aimed to determine the correlation between paradoxical septal motion and fQRS after coronary artery bypass grafting (CABG). METHODS We retrospectively reviewed the hospital records showing scintigraphic images and electrocardiograms (ECG) of the patients who had undergone CABG. The patients were classified based on the evaluation of motion and thickening of the septal wall. The patients with regular thickening of the septal wall and abnormal motion were classified as PSM (+) group. The patients with normal motion and thickening of the septal wall were classified as PSM (-) group. fQRS complexes are defined as various RSR patterns either with or without Q-waves on a 12-lead resting ECG. RESULTS PSM was found to be more common in fQRS patients (p < 0.001). PSM was seen in 91.4 % of cases with fQRS and in 79.8 % of cases without fQRS. No significant differences were found in the phase analysis parameters. A correlation was found between septal wall motion values and the presence of fQRS (r = 0.197, p = 0.012). CONCLUSION fQRS was associated with PSM. fQRS may cause PSM in patients with CABG without left bundle branch block due to a conduction defect. PSM and fQRS are predictive of cardiac mortality. Patients diagnosed with PSM and fQRS, should be monitored closely.

Abstract
OBJECTIVES Uric acid (UA) is a strong marker of cardiovascular disease. Therefore, we aimed to determine the relationship between serum UA levels and cardiovascular events in patients in the early period of their acute myocardial infarction. STUDY DESIGN This retrospective study included 586 consecutive patients with ST-elevated myocardial infarction (STEMI) who were admitted to the hospital between March 2010 and February 2012. The study population was divided into two groups; the first group included hyperuricemic patients (n=107; uric acid level >6 mg/dl in women and >7 mg/dl in men), and the second group included patients with normal UA level (n=479). Multivariate analysis was used to demonstrate the predictive value of UA levels in groups. RESULTS Patients in the hyperuricemic group were older (median 66 years vs. 60 years, p=0.001), and the ratio of female patients was higher (35.5% vs. 16.9%, p=0.001). Patients with hyperuricemia had a significantly higher incidence of in-hospital cardiovascular mortality than the normal group (15.9% vs. 3.1%, p<0.001). Advanced heart failure (class ≥ 3) was more frequent among hyperuricemic patients (17.8% vs. 8.8%, p=0.006). Age ≥ 70 years, chest pain duration >6 hours and hyperuricemia (hazard ratio (HR): 1.83, 95% confidence interval: 1.02-3.27; p=0.041) were found to be independent predictors of advanced heart failure. Hyperuricemia was found to be an independent predictor of in-hospital cardiovascular mortality in multivariate analyses (HR: 5.32, 95% confidence interval: 2.46-11.49; p=0.001). CONCLUSION This study showed that a high serum UA level is an independent predictor of cardiovascular mortality and morbidity during the in-hospital period of STEMI.

Predictive value of elevated neutrophil-lymphocyte ratio for left ventricular systolic dysfunction in patients with non ST-elevated acute coronary syndrome. Pak J Med Sci 2015; 31:159-63. [PMID: 25878635 PMCID: PMC4386178 DOI: 10.12669/pjms.311.5967] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/03/2014] [Revised: 09/17/2014] [Accepted: 09/27/2014] [Indexed: 12/23/2022] Open
Abstract
Objective: We aimed to study the predictive value of the neutrophil-lymphocyte ratio (NLR) for left ventricular systolic dysfunction (LVSD) in patients with non ST-elevated acute coronary syndrome (NST-ACS). Methods: A total of 405 patients (mean age 62 years and 75% male) with NST-ACS were included in the study. The study population was divided into tertiles based on admission NLR values. The low, medium and high tertiles defined as NLR≤1.81 (n=135), 1.81<NLR≤3.2 (n=135) and NLR>3.2 (n=135), respectively. Results: The patients in the high NLR group were older (p<0.001), have higher rate of diabetes mellitus (p=0.028) and non-ST elevated myocardial infarction (NSTEMI) (p<0.001) and have lower left ventricular ejection fraction (LVEF) (p<0.001). Baseline WBC (p=0.02) and neutrophil (p<0.001) levels and NLR (p<0.001) were significantly higher, baseline hemoglobin (p=0.044), hematocrit (p=0.019) and lymphocyte (p<0.001) levels were significantly lower in the high NLR group. NLR was negatively correlated with LVEF in correlation analysis. An NLR >3.2 and age ≥70 were found to be an independent predictor of systolic dysfunction in multivariate analyses. Conclusion: An NLR >3.2 is a useful predictor for LVSD in patients with NST-ACS. The practice of using an NLR count on admission may be useful for identifying high-risk patients and their associated treatment methods.

Abstract
BACKGROUND Iatrogenic acute dissection of the ascending aorta following coronary angiography and percutaneous intervention is rare. This complication, if not managed urgently, can have critical results. CASE REPORT We present the case of a 70 year-old woman who was treated by primary percutaneous coronary intervention (PCI) of the right coronary artery (RCA) for acute inferior myocardial infarction; however, the procedure was complicated by anterograde dissection of the RCA with a simultaneous retrograde propagation to the proximal part of the ascending aorta. Successful stenting of the entry point was able to heal the RCA and restrict the retrograde propagation to the ascending aorta. The aortic dissection was monitored by means of computerised tomography and the dissection repaired itself spontaneously within a day. CONCLUSION Treatment of the aorta coronary dissection (ACD) by urgent osteal stenting is a less invasive treatment compared with surgical treatment in appropriate cases. We demonstrated that immediate osteal stenting should be performed in ACD.

Abstract
BACKGROUND Fragmented QRS (fQRS) complexes on 12-lead electrocardiography (ECG) have been reported to be predictors of cardiac events and all-cause mortality in coronary artery disease (CAD). AIM To investigate the relationship between fQRS complexes and SYNTAX and Gensini scores in patients with acute coronary syndrome (ACS). METHODS A total of 302 patients (223 men and 79 women) with ACS (133 ST elevated myocardial infarction [STEMI], 107 non-STEMI [NSTEMI], and 62 unstable angina pectoris [USAP]) were evaluated retrospectively in this study. An fQRS pattern was found in 70 patients (fQRS group) but was not found in 232 patients (non-fQRS group). SYNTAX score > 22 and Gensini score > 20 were defined as high SYNTAX and Gensini scores. The relationship between the presence of fQRS on 12-lead ECG and SYNTAX and Gensini scores was assessed. RESULTS SYNTAX score (p < 0.001), Gensini score (p < 0.001), NYHA class (p < 0.001), QRS duration (p < 0.001), number of disease vessels (p = 0.003), and high sensitive troponin T levels (p = 0.026) were significantly higher in the fQRS group. The number of fQRS leads (HR 5.79, 95% CI 2.78-12.06, p < 0.001, HR 3.41, 95% CI 1.32-8.78, p = 0.016, respectively) was found to be an independent predictor of high SYNTAX score and high Gensini score in multivariate analysis. CONCLUSIONS The number of fQRS leads on 12-lead ECG on admission is associated with the severity and complexity of CAD in patients with ACS.

Abstract
Objective: The prognostic value of the Global Registry of Acute Coronary Events (GRACE) risk score (GRS) and the Thrombolysis In Myocardial Infarction (TIMI) risk index (TRI) has been reported in coronary artery disease (CAD) patients. We aimed to evaluate the relationship between the GRS, TRI, and severity of CAD evaluated by SYNTAX score (SS) in patients with acute coronary syndrome (ACS). Methods: Patients with ACS who were admitted to the coronary care unit of our institution were retrospectively evaluated in this study. A total of 287 patients with ACS [154 non-ST elevated ACS (NSTE-ACS), 133 ST elevated myocardial infarction (STEMI)] were included in the study. The GRS and TRI were calculated on admission using specified variables. The severity of CAD was evaluated using the SS. The patients were divided into low (GRS<109)-, intermediate (GRS 109-140)-, and high (GRS>140)-risk groups and group 1 (TRI<17), group 2 (TRI 17-26), and group 3 (TRI>26) according to GRS and TRI scores. A Pearson correlation analysis was used for the relation between GRS, TRI, and SS. Results: Patients with a history of coronary artery bypass surgery, those who had missing data for calculating the GRS and TRI, and those whose systolic blood pressure (SBP) was more than 180 mm Hg or whose diastolic blood pressure (DBP) was more than 110 mm Hg were excluded from the study. Were excluded from the study. There were significant differences in mean age (p<0.001), heart rate (p<0.001), SS (p<0.001), TRI (p<0.001), rate of NSTE-ACS (p<0.001), and STEMI (p<0.001) in all patients between the risk groups. There was a positive significant correlation between the GRS and the SS (r=0.427, p<0.001), but there were no significant correlation between the TRI and SS (r=0.121, p=0.135). The area under the ROC curve value for GRS was 0.65 (95% CI: 0.56-0.74, p=0.001) in the prediction of severity of CAD. Conclusion: The GRS is more associated with SS than TRI in predicting the severity of CAD in patients with ACS.

Abstract
OBJECTIVE The liver is an important organ for various aspects of glucose metabolism, including glucose uptake, storage, and synthesis. It is a major organ in the metabolic process with perfusion provided by both the portal vein and hepatic artery. In diabetic patients organ perfusion is reduced and this is linked to atherosclerosis, and as a result complications occur. In this study, we aimed to evaluate liver perfusion by scintigraphic methods in diabetic patients. DESIGN AND PATIENTS We retrospectively investigated 1,100 myocardial perfusion scintigraphies taken between January 2011 and December 2012 at Canakkale Onsekiz Mart University Medical Faculty Nuclear Medicine Department. A total of 66 patients who were diagnosed with diabetes mellitus and had myocardial perfusion scintigraphies were included in the study. The control subjects included 127 patients without diabetes mellitus who were chosen at random. Patients with chronic liver disease were not included in the study. The values from liver regions of interest (liver-ROI) rates and heart regions of interest (heart-ROI) rates were compared between the patients and controls. RESULTS Patients were grouped according to the presence of diabetes. In the diabetes mellitus group, the liver-ROI average was lower (p = 0.66) than in the controls. In the control group, the average liver-ROI/heart-ROI ratios were higher than the ratio in the diabetes mellitus group (p = 0.019). Multivariate variance analysis showed that the diabetes mellitus liver-ROI/heart-ROI ratio was independent of other risk factors (p = 0.003; F: 9.6). Powered by Editorial Manager(®) and ProduXion Manager(®) from Aries Systems Corporation. CONCLUSIONS This study shows that liver perfusion in diabetic patients is reduced compared with those without diabetes. Prospective studies with larger patient groups are required.

Abstract
OBJECTIVE Hepcidin is an acute-phase reactant produced in the liver displaying intrinsic antimicrobial activity. There are few studies about hepcidin considered to be acute and chronic inflammatory marker in acute coronary syndromes patients. We investigated in our study whether the level of hepcidin has increased in the acute phase of non-ST elevation myocardial infarction patients (NSTEMI) known as acute inflammatory aggravation of chronic atherosclerotic process. METHODS Seventy patients with NSTEMI and twenty healthy people were recruited as controls in this observational cross-sectional study. Serum hepcidin levels were determined by ELISA, and troponin levels were measured by standard laboratory methods. Levels of hepcidin and troponin were measured at admission and 6 hours later. Mean values of continuous variables were compared between groups using the Student t-test or Mann-Whitney U test, according to whether normally distributed or not, as tested by the Kolmogorov-Smirnov test. Serum troponin and hepcidin levels measured at admission and after 6th hours were compared using paired t-test. RESULTS Hepcidin level was similar between NSTEMI and controls at admission (24.55±32.13, 23.67±33.62 ng/mL, p>0.05, respectively). Also, serum hepcidin levels did not change significantly from baseline in blood samples taken after 6 hour from admission in NSTEMI patients (24.55±32.13 ng/mL, 29.75±31.48 ng/mL, p=0.62, respectively). However, serum troponin levels were increased significantly compared to baseline (0.29±3.56, 2.92±7.2 ng/mL, p<0.01). CONCLUSION Our findings suggest that hepcidin could not be use as a marker of myocardial necrosis in acute phase such as troponin in patients with NSTEMI.

Abstract
Platelet activation plays a pivotal role in acute coronary syndrome (ACS). We investigated the relationship between platelet distribution width (PDW) and severity of coronary artery disease (CAD) in patients with ACS. A total of 502 patients with ACS were enrolled. High (n = 151) and low PDW (n = 351) groups were defined as patients having values in the third tertile (>17%) and lower 2 tertiles (≤17%). There were significantly higher Gensini score (44 [10-168] vs. 36 [2-132], P < .001), and neutrophil-lymphocyte ratio (3.1 [0.8-12.4] vs. .2.5 [0.3-13], P = .012) and baseline platelet counts were significantly lower (220 [61-623] vs. 233 [79-644] 10(3)/mm3, P = .022) in the high PDW group. The variables PDW >17%, diabetes mellitus, and myocardial infarction were found to be associated with high Gensini score (odds ratio [OR]: 1.91, 95% confidence interval [CI]: 1.27-2.88, P = .002; OR: 2.85, 95% CI: 1.91-4.25, P < .001; OR: 2.67, 95% CI:1.74-4.1, P < .001, respectively). An increased PDW (>17%) is associated with severity of CAD in patients with ACS.

Abstract
OBJECTIVE In this study we aimed to investigate the relationship between lipocalin-2 (LCN2) levels and cardiovascular risk in patients with polycystic ovary syndrome (PCOS). STUDY DESIGN Fifty patients with PCOS and 44 healthy women as controls were enrolled in the study. Laboratory and echocardiographic examinations were performed between the second and fifth days of the menstrual cycle. Serum LCN2 levels were measured with an enzyme-linked immunosorbent assay (ELISA) method. RESULTS Serum LCN2 levels were significantly lower in PCOS patients (75.8 [51.4-131.2] ng/ml vs. 85.3 [56.7-138.5] ng/ml, p=0.038). Carotid intima-media thickness (CIMT) was increased in patients with PCOS compared to controls (0.61±0.13mm vs. 0.50±0.07mm, p=0.001). Aortic strain was lower in patients with PCOS. Aortic stiffness (β index) was significantly increased and distensibility was decreased in PCOS patients compared to control subjects. Serum LCN2 levels and the presence of PCOS were associated with CIMT in Spearman correlation analysis (p=0.05 and p<0.001) in all participants. There was no statistically significant relationship between LCN2 levels and CIMT in patients with PCOS (p=0.238). CONCLUSION In the present study, we found that LCN2 levels were low in women with PCOS. Although our patients with PCOS had elevated cardiac risk, there was no correlation between LCN2 levels and early findings of atherosclerosis.

Abstract
BACKGROUND Ventricular ectopic beats (VEBs) are usually considered a benign condition that can be managed with conservative measures. Heart rate variability (HRV), which is one of the most important methods for assessing autonomic activity, is a noninvasive, quantitative method of analyzing autonomic effects on the heart. We aimed to investigate the risk of arrhythmia in patients with VEBs and without cardiovascular disease by using HRV parameters. METHODS Patients with frequent VEBs (more than 30 times in 1 hour, according to the Lown classification) were identified. Identified patients were evaluated by 24-hour ECG recording. Our study included 43 patients with frequent VEBs and 43 controls. RESULTS General characteristics of the study population were similar. The LF (low frequency)/HF (high frequency) ratio was significantly higher in the frequent VEBs group than in the control group (P < 0.001). The rate of paroxysmal atrial fibrillation (PAF) was higher in the frequent VEB group than in the control group (P = 0.003). The number of VEBs was correlated with LF/HF ratio and PAF (r = 0.339, P = 0.001 and r = 0.294, P = 0.006, respectively). CONCLUSIONS Our study showed that the sympathetic nervous system is dominant in young patients with VEBs and without significant comorbidities. There is a higher risk of atrial fibrillation in patients with VEBs and they should be monitored closely for atrial fibrillation.

Objective: Red cell distribution width (RDW) has been reported to be a predictor of cardiac events in coronary artery disease (CAD). Here, we hypothesized that RDW level on admission would be predictive of adverse outcomes in non-ST elevation acute coronary syndrome (NST-ACS). Methods: In total, 202 patients with NST-ACS (159 males and 43 females) were retrospectively analyzed. The patients were divided into two groups based on the 50th percentile of admission RDW levels. A high RDW group (n=100) was defined as those patients having RDW levels of >14.0. The relationship between RDW and primary endpoint (cardiovascular death), secondary endpoints [(reinfarction, repeat target vessel revascularization-percutaneous/surgical)], and major adverse cardiac events (MACE) were assessed. The median follow-up time was 18 (13-24) months. Results: The patients in the high RDW group were older (62.9 vs. 57.5, p=0.001). Multivessel disease, low-density lipoprotein, creatinine, platelet, CK-MB, troponin I, and RDW were higher (p=0.047, p=0.003, p=0.012, p=0.012, p=0.017, p<0.001, respectively), and gender (male/female), ejection fraction, and hemoglobin levels were lower (p=0.021, p=0.04, p=0.016, respectively) in the high RDW group. Cardiovascular death and MACE were higher in the high RDW group (16% vs. 4.9%, p=0.01, 52% vs. 31.4%, p=0.003, respectively). By multiple regression analysis in 202 patients, age >65 and RDW >14.0% on admission were found to be powerful independent predictors of cardiovascular mortality (OR: 4.5, 95% CI: 1.5-13.1, p=0.005, OR: 3.0, 95% CI: 1.0-8.9, p=0.039, respectively). Conclusion: A high RDW level on admission is associated with increased long-term mortality in patients with NST-ACS.

Assessment of left-atrial strain parameters in patients with frequent ventricular ectopic beats without structural heart disease. Int J Cardiovasc Imaging 2014; 30:1027-36. [PMID: 24752954 DOI: 10.1007/s10554-014-0423-y] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/18/2014] [Accepted: 04/11/2014] [Indexed: 11/26/2022]
Abstract
Ventricular ectopic beats (VEBs) are often encountered in daily clinical practice. Clinical significance of VEBs seen in patients without structural cardiovascular diseases is controversial. We aimed to investigate the effects of VEBs on left atrium (LA) function using speckle tracking echocardiography with LA strain parameters. Patients with frequent VEBs (more than 30 times in 1 h, according to the Lown classification) were identified. Identified patients were evaluated by speckle tracking methods. There were 40 patients with frequent VEBs and 40 controls in our study. The general characteristics were similar of the study population. The LA global longitudinal strain parameters were significantly different. Global Peak atrial longitudinal strain (PALS) (38.39 ± 7.93 vs. 44.15 ± 6.71, p = 0.001) and peak atrial contraction strain (PACS) (16.37 ± 4.58 vs. 20.49 ± 3.65, p = 0.000) were revealed significantly lower in the VEBs group. Time to peak longitudinal strain (TPLS) was found significantly longer in the VEBs group [485.5 (352-641) vs. 435 (339-516.5) p = 0.000]. Number of VEBS was correlated with TPLS (r = 0.499, p = 0.000). PALS and PACS were negatively correlated with number of VEBs (r = -0.348, p = 0.002 and r = -0.444, p = 0.000, respectively). We described that in this study, The LA functions are affected by VEBs adversely. This deterioration is increasing as the number of VEBs.

Abstract
Background Platelet-to-lymphocyte ratio (PLR) is a new prognostic marker in coronary artery disease. We aimed to evaluate the relationship between PLR and in-hospital mortality in patients with ST-elevated acute myocardial infarction (AMI). Material/Methods The present study included 636 patients with ST-elevated AMI. The study population was divided into tertiles based on their admission PLR. Patients having values in the third tertile was defined as the high PLR group (n=212) and those having values in the lower 2 tertiles were defined as the low PLR group (n=424). Results Risk factors of coronary artery disease and treatments administered during the in-hospital period were similar between the groups. Male patient ratio was found to be lower in the high PLR group (73% vs. 82.8%, p=0.004). In-hospital mortality was increased in the high PLR group when compared to the low PLR group (12.7% vs. 5.9%, p=0.004). The PLR >144 was found to be an independent predictor of in-hospital cardiovascular mortality (HR: 2.16, 95% CI: 1.16–4.0, p=0.014). Conclusions This study showed that PLR is an independent predictor of cardiovascular mortality in patients with ST-elevated AMI.

Abstract
Objective The prognostic value of a high platelet-lymphocyte ratio (PLR) has been reported in patients with non-ST elevated myocardial infarction (NSTEMI) and different oncologic disorders. We aimed to evaluate the predictive value of the PLR for left ventricular systolic dysfunction (LVSD) in patients with non-ST elevated acute coronary syndrome (NST-ACS). Methods A total of 220 patients with NST-ACS were included in the study. The study population was divided into tertiles based on admission PLR values. High (n=73) and low PLR (n=147) groups were defined as patients having values in the third tertile (>135.6) and lower 2 tertiles (≤135.6), respectively. Left ventricular dysfunction was defined as ejection fraction ≤40%, and related variables were evaluated by backward conditional binary logistic regression analysis. Results The patients in the high PLR group were older (p<0.001) and had a higher rate of previous myocardial infarction and NSTEMI (p=0.046, p=0.013, respectively). There were significantly more coronary arteries narrowed (p=0.001) and lower left ventricular ejection fraction (p<0.001) in the high PLR group. Baseline platelet levels were significantly higher (p<0.001) and triglyceride and lymphocyte levels were significantly lower (p=0.009 and p<0.001, respectively) in the high PLR group. PLR >135.6 was found to be an independent predictor of systolic dysfunction in the multivariate analyses (ß: 0.306, 95% confidence interval: 0.151-0.619; p=0.001). Conclusion A high PLR is a strong and independent predictor for LVSD in patients with NST-ACS.

Abstract
OBJECTIVE Endothelial dysfunction is an independent risk factor for cardiovascular events. We aimed to investigate the relationship between endothelial dysfunction and gestational diabetes mellitus and impaired glucose tolerance. METHODS Pregnant women who had impaired glucose metabolism in the 75-g oral glucose tolerance test (OGTT) and their age- and body mass index-matched controls were included in the study and assessed for flow-mediated vasodilatation to evaluate endothelial dysfunction. RESULTS A total of 51 patients participated in the study. There were 20 patients in the control group, 13 in the impaired glucose tolerance group and 18 in the gestational diabetes mellitus group. Flow-mediated vasodilatation measured at the 60th and 120th seconds were significantly lower in the impaired glucose tolerance and gestational diabetes mellitus groups than in the control group (8.5 ± 5.7 and 8.9 ± 6.5 versus 14.9 ± 9.0, p=0.022 and 6.2 ± 6.7 and 5.2 ± 5.0 versus 12.0 ± 8.3, p=0.011, respectively). CONCLUSIONS Patients with gestational diabetes mellitus and impaired glucose tolerance have impaired endothelial dysfunction. Delivery might have protective effects on endothelial functions. The significance of impaired endothelial dysfunction for pregnant women must be investigated, and if needed, lifestyle changes might be suggested, according to the determined importance of the endothelial dysfunction.

Abstract
Objective: In this study, we aimed to demonstrate whether the presence of fragmented QRS (fQRS) is associated with the frequency of premature ventricular contractions (PVCs). Methods: We retrospectively analyzed 282 cases by 24-hour Holter monitorings (HMs) between August 2012 and February 2013. Firstly, the patients were divided into 2 groups with respect to presence of fQRS and then divided into 3 groups with respect to frequency of PVCs as Group 1: seldom PVC (<120 PVCs/day), Group 2: moderate-frequency PVC (120-720 PVCs/day), and Group 3: frequent PVC (>720 PVCs/day). We investigated the predictors of frequent PVCs by using multinomial logistic regression analysis. Results: Ninety-eight patients had fQRS. There was no difference between the 2 groups with respect to body mass index, gender, hypertension, and diabetes mellitus. Patients with fQRS were older (54.9±15.6 vs. 47.0±16.3, p<0.001) and had more family history of coronary artery disease (25% vs. 13%, p=0.012). Patients with fQRS was more likely to be on aspirin therapy (28.6% vs. 10.4%, p<0.001) and have a larger left atrium diameter (33.5±5.7 vs. 30.4±5.8, p=0.001). Presence of fQRS was significantly associated with the frequency of PVCs (for frequent PVC 27.7% vs. 7.6%, p<0.001; for moderate-frequency PVC 18.4% vs. 11.4%, p=0.012); 26.2% of Group 1 (n=202) had fQRS, 46.2% of Group 2 (n=39) had fQRS, and 65.9% of Group 3 (n=41) had fQRS. In the multinomial regression analysis, only age (odds ratio: 4.24, 95% confidence interval 2.08-8.64, p=0.001) and fQRS (odds ratio: 2.11, 95% confidence interval 1.00-4.45, p=0.05) were predictors of frequent PVCs. Conclusion: This study demonstrated that the presence of fQRS is associated with frequent PVCs in patients without overt structural heart disease.

Abstract
Background Red cell distribution width (RDW) and fragmented QRS (fQRS) complexes have also been reported to be predictors of cardiac events and all-cause mortality in coronary artery disease (CAD). We aimed to investigate the association of serum red cell distribution width (RDW) levels and fQRS in patients with non-ST elevated acute coronary syndrome (NST-ACS). Material/Methods We retrospectively evaluated a total of 251 patients (191 men and 60 women) with NST-ACS. The NST-ACS consisted of unstable angina (UA) and non-ST elevated myocardial infarction (NSTEMI). The fQRS pattern was defined as the presence of an additional R’ or crochetage wave, notching in the nadir of the S wave or fragmentation of the RS or QS complexes in 2 contiguous leads corresponding to a major coronary artery territory. The relationships between the RDW and fQRS were assessed. Results The patients in the fQRS group were older, left ventricular ejection fraction (LVEF) levels were significantly lower, and baseline RDW and troponin levels were significantly higher than in the group without fQRS. There were positive correlations between age, number of coronary arteries narrowed, and RDW, and negative correlations between triglyceride, LVEF, and RDW in study patients. There were positive correlations between number of fQRS leads, age, and RDW, and negative correlations between triglyceride, LVEF, and RDW in NSTEMI patients. Conclusions Our results indicate that an elevated RDW values is associated with fQRS in NST-ACS. Elevated RDW values and fQRS together may be useful for identifying NSTEMI patients in NST-ACS.

Abstract
Background We examined the effects of ACE, PAI-1 and eNOS gene polymorphisms on endothelial function. The genes are related to atherosclerosis and endothelial dysfunction in coronary slow flow (CSF). Methods Thirty-three patients with angiographically proven CSF and 48 subjects with normal coronary flow were enrolled in this study. Coronary flow patterns were determined by the thrombolysis in myocardial infarction (TIMI) frame count method. Endothelial function was assessed in the brachial artery by endothelium-dependent flow-mediated dilatation (FMD). PAI-1 4G/5G, eNOS T-786C and ACE I/D polymorphisms were determined by polymerase chain reaction (PCR) amplification. Results No difference was found between the groups regarding age, heart rate and blood pressure. Males were more prevalent among patients with CSF than control subjects (58.8 vs 29.8%, p = 0.009). Mean TIMI frame counts were significantly higher in CSF patients (24.2 ± 4.0 vs 13.1 ± 2.5 fpm, p = 0.001). FMD was significantly lower in CSF patients than in the controls (4.9 ± 6.6 vs 7.9 ± 5.6%, p = 0.029). TIMI frame count and FMD were found to be negatively correlated in a correlation analysis (r = –0.269, p = 0.015). PAI-1 4G/5G, eNOS T-786C and ACE I/D polymorphisms were similar in the two groups. Conclusions This study showed that endothelial function was impaired in patients with CSF. PAI-1, ACE and eNOS polymorphisms were not related to CSF in our study population.

Abstract
OBJECTIVE Prior studies have demonstrated the relationship between cardiovascular diseases and fragmented QRS (fQRS). fQRS was also associated with ventricular arrhythmias. Our objective was to find out the relationship between fQRS and paroxysmal atrial fibrillation (PAF). METHOD A total of 301 patients without overt structural heart disease were prospectively included in the study. Patients were divided in to 2 groups according to presence of fQRS. Multivariate logistic regression analysis was used to assess the predictive value of fQRS for predicting PAF. RESULTS One hundred and three patients had fQRS. Patients with fQRS were older (53±16.8 vs 45.3±17.2, p<0.001), with larger left atrium (LA) (33.2±5.9 vs 30.1±5.9 mm, p=0.001), with thicker interventricular septum (IVS) (10.2±1.9 vs 9.5±2.3 mm, p=0.032), more diabetic (19.8 vs 10.6%, p=0.029) and have more PAF episodes (22.3 vs 4.1%, p<0.001) in comparison with patients without fQRS. fQRS was an independent predictor of detecting PAF episode (odds ratio, 9.69; 95% confidence interval, 2.46-38.15, p=0.001). Hypertension and diabetes mellitus were also predictive. CONCLUSION The presence of fQRS independently predicted PAF episodes in holter monitoring (HM). Further studies are needed to clarify the clinical implications of this finding.

Abstract
OBJECTIVE To investigate intercellular adhesion molecule-1 (ICAM1) and angiotensinogen (AGT) gene polymorphisms, as related to atherosclerosis and endothelial dysfunction, in coronary slow flow (CSF). SUBJECTS AND METHODS The participants in this study were 48 patients with CSF and 67 patients with normal coronary flow as controls. The K469E polymorphism of ICAM1 (rs5498) and the T207M polymorphism of AGT (rs4762) were determined using the polymerase chain reaction amplification method. RESULTS Baseline demographic parameters were similar in both groups. The mean thrombolysis in myocardial infarction frame count was significantly higher in patients with CSF (23.8 ± 5.1) compared to the controls (13.3 ± 2.6, p < 0.001). A significant association was found between the ICAM1 K allele and CSF (OR: 1.96, 95% CI: 1.15-3.35, p = 0.013). There was no difference in the frequency of AGT T207M genotypes in the patients with CSF and the control subjects. CONCLUSION This study showed that K469E polymorphisms of ICAM1 that play a role in atherosclerotic pathogenesis are related to CSF.
