WOS: 000509346000005 PubMed: 31568270 Objectives In this study, we evaluated and compared the level of myocardial ischaemia caused by cardiac syndrome X (CSX) and coronary slow flow (CSF) with single photon emission computed tomography myocardial perfusion imaging (SPECT-MPI), and determined if changes in the level of myocardial ischaemia exist in CSF and CSX cases according to thrombolysis in myocardial infarction frame count (TFC). Materials and methods The study population consisted of 66 patients with CSF and 78 angiographically normal patients (36 of them with CSX and 42 of them healthy controls). The coronary flow rates of all patients were documented using TFC. Subsequently, all patients were evaluated with SPECT-MPI and categorized into the following groups according to their results: patients with CSF, patients with CSX, and patients with normal coronary arteries. Finally, we investigated whether a relationship existed between the SPECT-MPI and TFC results from these three groups. Results All ischaemia scores for MPI were significantly higher in the CSF group than in the CSX and control groups (P < 0.05). TFC was significantly associated with the severity of ischaemia in the CSF patients. There was a significant positive correlation between the summon difference score (SDS) and mean TFC value (P < 0.05) as well as between the SDS and each individual coronary TFC value in the CSF patients (P < 0.05). The number of vessels involved in CSF was positively correlated with the SDS. Conclusion CSF is associated with more severe myocardial ischaemia than CSX. The level of myocardial ischaemia on SPECT-MPI was correlated with the TFC and the number of affected coronary vessels in patients with CSF. These results suggest that CSF is a more serious clinical entity than CSX, and that the clinical severity of CSF appears to increase as the coronary flow rate decreases.

WOS: 000460493900011 PubMed: 30621931 Background: Recent studies have demonstrated that right ventricular (RV) dysfunction and increased pulmonary artery pressure may be frequent in patients with upper airway obstruction. In this study, we evaluated atrial conduction delays in patients with upper airway obstruction secondary to nasal septum deviation (NSD). Methods: A total of 32 patients with upper airway obstruction secondary to NSD undergoing a septoplasty procedure were enrolled in this study. Preoperative electrocardiography and transthoracic echocardiography were performed in all patients who underwent surgery. The mean pulmonary artery pressure (mPAP) and atrial conduction time (ACT) were recorded before and 6 months after the surgical procedures. Results: The PAP was significantly lower postoperatively than preoperatively (20.75 +/- 4.83 vs. 24.68 +/- 5.26; P < 0.001). The postoperative Electromechanical Delay of Mitral septal wall (EMD-MS) value was significantly lower than that preoperatively (46.20 +/- 8.5 vs. 40.5 +/- 9.9; P < 0.001). The postoperative Electromechanical Delay of Mitral lateral wall (EMD-ML) value decreased significantly compared to the preoperative period (46.3 +/- 7.4 vs. 40.6 +/- 9.3; P < 0.001). The postoperative Electromechanical Delay of Tricuspit lateral wall (EMD-TL) value was significantly lower than that preoperatively (43.8 +/- 7.0 vs. 38.1 +/- 9.1; P < 0.001). There was no significant change in pre- or postoperative measurements of inter- and intra-atrial conduction delays. Conclusions: We demonstrated that upper airway obstruction secondary to NSD causes a significant increase in mPAP and a significant delay in ACT, which improved after nasal septoplasty. According to these results, we conclude that upper airway obstruction may be an important risk factor for pulmonary arterial hypertension, RV dysfunction, and atrial arrhythmias, especially in unoperated cases.

In the current study, we evaluated the predictors of in-hospital mortality of STEMI complicated with CS. Methods In this retrospective study, we evaluated the predictive value of baseline characteristics, angiographic, echocardiographic and laboratory parameters on in-hospital mortality of 319 patients with STEMI complicated with CS who were treated with primary percutaneous coronary intervention. Patients were divided into two groups consisting of survivors and non-survivors during their index hospitalisation period. Results The mortality rate was found to be 61.3% in the study population. At multivariate analysis after adjustment for the parameters detected in univariate analysis, chronic renal failure, Thrombolysis In Myocardial Infarction (TIMI) post percutaneous coronary intervention (PCI)

Background: Inflammatory mechanisms play an important role in both atherosclerosis and stroke. There are several inflammatory peripheral blood count markers associated with carotid artery stenosis degree, symptomatic carotid artery lesions and carotid artery stent restenosis that reported in previous studies. However, the prognostic role of the blood cell counts and their ratios in predicting in-hospital and long-term outcomes in patients undergoing carotid artery stenting (CAS) has not been comprehensively investigated. Systemic immune-inflammation index (SII) proved its' efficiency in patients with solid tumors and its' role was rarely examined in cardiovascular disorders and stroke. The current study evaluated the effect of this novel risk index on in-hospital and long-term outcomes in a large patient population who underwent CAS. Method: A total of 732 patients with carotid artery stenosis who underwent CAS were enrolled to the study. SII was calculated using the following formula: neutrophil-to-lymphocyte ratio pound total platelet count in the peripheral blood (per mm3) and the patients were stratified accordingly: T1, T2 and T3. In-hospital and 5-year outcomes were compared between the tertiles of SII. Results: During the hospitalization, major stroke, ipsilateral stoke, myocardial infarction, death and major adverse cardiovascular events (MACE) rates were significantly higher in high SII level (T3) compared to SII levels (T1 and 2). In longterm outcomes, ipsilateral stroke, major stroke, transient ischemic attack, death, and MACE were significantly higher in the patients with higher SII level (T3). The 5-year Kaplan-Meier overall survival for T1, T2, and T3 were 97.5%, 96.7% and 86.0% respectively. In-hospital and 5-year regression analyses demonstrated that high SII was independently associated with MACE and mortality. Conclusion: SII was independently associated with in-hospital and long-term clinical outcomes in patients undergoing CAS. Immune and inflammation status, as assessed easily and quickly using SII, has a good discriminative value in these patients. WOS:000686903400007 2-s2.0-85109196298 PubMed: 34242858

Objective: In this study, we aimed to determine the predictive value of the CHA2DS2VASc score for acute stent thrombosis in patients with an ST elevation myocardial infarction treated with a primary percutaneous coronary intervention (pPCI). Methods: This was a retrospective study conducted among 3,460 consecutive patients with STEMI who underwent a pPCI. The stent thrombosis was considered a definite or confirmed event in the presence of symptoms suggestive of acute coronary syndrome and angiographic confirmation of stent thrombosis based on the diagnostic guidelines of the Academic Research Consortium. The stent thrombosis was classified as acute if it developed within 24 h. Results: The mean CHA2DS2VASc score was 3.29 ± 1.73 in the stent thrombosis group, whereas it was 2.06 ± 1.14 in the control group (p < 0.001). In multivariable logistic regression analysis, CHA2DS2VASc scores ≥ 4 were independently associat ed with acute stent thrombosis (OR = 1.64; 95% CI 1.54–1.71, p < 0.001). In a receiver operating characteristic curve ana­lysis, the best cut-off value for the CHA2DS2VASc score was ≥4, with 60% sensitivity and 73% specificity. Of note, pa tients with a CHA2DS2VASc score of 4 had a 4.3 times higher risk of acute stent thrombosis compared to those with a CHA2DS2VASc score of 1. Conclusions: The CHA2DS2VASc score may be a significant independent predictor of acute stent thrombosis in patients with STEMI treated with a pPCI. Therefore, the CHA2DS2VASc score may be used to assess the risk of acute stent thrombosis in patients with STEMI following a pPCI.

Keskin, Muhammed/0000-0002-4938-0097; Cinar, Tufan/0000-0001-8188-5020 WOS: 000458270500009 PubMed: 30109454 In anterior ST-segment elevation myocardial infarction (STEMI), attention paid mainly to the left ventricle. The predictive significance of right ventricular (RV) dysfunction in patients with anterior STEMI has been frequently neglected. In this study, we evaluated the prognostic effect of RV dysfunction on in-hospital and long-term outcomes in patients with first anterior STEMI. A total of 350 patients without known coronary artery disease with first anterior STEMI and treated with primary percutaneous coronary intervention were prospectively enrolled in this study. In-hospital and long-term outcomes were compared between two groups of with or without RV dysfunction. In-hospital mortality was significantly higher in the RV dysfunction group (26.7% vs. 1.6%, P

Keskin, Muhammed/0000-0002-4938-0097; kaya, adnan/0000-0002-9225-8353 WOS: 000453470000010 PubMed: 29962233 We evaluated the effect of serum potassium (K) deviation on in-hospital and long-term clinical outcomes in patients with ST-segment elevation myocardial infarction who were normokalemic at admission. A total of 2773 patients with an admission serum K level of 3.5 to 4.5 mEq/L were retrospectively analyzed. The patients were categorized into 3 groups according to their K deviation: normokalemia-to-hypokalemia, normokalemia-to-normokalemia, and normokalemia-to-hyperkalemia. In-hospital mortality, long-term mortality, and ventricular arrhythmias rates were compared among the groups. In a hierarchical multivariable regression analysis, the in-hospital mortality risk was higher in normokalemia-to-hypokalemia (odds ratio [OR] 3.03; 95% confidence interval [CI], 1.72-6.82) and normokalemia-to-hyperkalemia groups (OR 2.81; 95% CI, 1.93-4.48) compared with the normokalemia-to-normokalemia group. In a Cox regression analysis, long-term mortality risk was also higher in normokalemia-to-hypokalemia (hazard ratio [HR] 3.78; 95% CI, 2.07-7.17) and normokalemia-to-hyperkalemia groups (HR, 2.97; 95% CI, 2.10-4.19) compared with the normokalemia-to-normokalemia group. Ventricular arrhythmia risk was also higher in normokalemia-to-hypokalemia group (OR 2.98; 95% CI, 1.41-5.75) compared with normokalemia-to-normokalemia group. The current study showed an increased in-hospital ventricular arrhythmia and mortality and long-term mortality rates with the deviation of serum K levels from normal ranges.

Guvenc, Tolga Sinan/0000-0002-6738-266X; Keskin, Muhammed/0000-0002-4938-0097 WOS: 000415210400031 PubMed: 28575813 Background: Thrombolysis in Myocardial Infarction (TIMI) risk index (TRI) was recently evaluated in patients with acute myocardial infarction and found as an important prognostic index. In the current study, we evaluated the prognostic value of TRI in patients with moderate-high and high risk pulmonary embolism (PE) who were treated with thrombolytic agents. Methods: We retrospectively evaluated the in-hospital and long-term(4-year) prognostic impact of TRI in a total number of 456 patients with moderate-high and high risk PE. Patients were stratified by quartiles (Q) of admission TRI. Results: In-hospital analysis revealed significantly higher rates of in-hospital death for patients with TRI in Q4. After adjustment for confounding baseline variables, TRI in Q4 was associated with 2.8-fold hazard of in-hospital death. Upon multivariate analysis, admission TRI in Q4 vs. Q1-3 was associated with 3.1 fold hazard of 4-year mortality rate. Conclusion: TRI in Q4, as compared to Q1-3, was significantly predictive of short term and long-term outcomes in PE patients who treated with thrombolytic agents. Our data suggest TRI to be an independent, feasible, and cost effective tool for rapid risk stratification in moderate-high and high risk PE patients who treated with thrombolytic agents.

Gungor, Baris/0000-0002-8883-117X WOS: 000408984000010 PubMed: 28752145 OBJECTIVE: Red cell distribution width (RDW) and neutrophil to lymphocyte ratio (NLR) have been found to be associated with non-valvular atrial fibrillation (AF) and cardiovascular diseases. However, correlation of these parameters with presence of left atrial (LA) thrombus and/or spontaneous echo contrast (SEC) in patients with non-valvular AF has not been clarified. This study was an investigation of correlation of RDW, NLR, and clinical risk factors with LA thrombus and dense SEC in patients with non-valvular AF in the Turkish population. METHODS: The demographic, laboratory, and echocardiographic properties of 619 non-valvular AF patients who underwent transesophageal echocardiography (TEE) examination before direct current cardioversion (DCCV) or AF ablation treatment were retrospectively investigated. Complete blood count (CBC) and biochemical parameters were studied 6 to 12 hours before TEE examination. Left atrial stasis (LAS) markers were noted as presence of left atrial/left atrial appendage (LA/LAA) thrombus or dense spontaneous echo contrast (DSEC). RESULTS: Total of 325 (52%) patients with LAS were compared with 294 patients (48%) without LAS. In the LAS group, there were 274 (84%) patients with LA/LAA thrombus and 51 (16%) patients with DSEC. LAS (+) group, values for RDW (14.85 +/- 1.48 vs. 13.77 +/- 1.30; p6 months, and international normalized ratio

Ozde, Cem/0000-0001-8846-9185 WOS: 000514249400013 PubMed: 31812229 Energy drinks (EDs) are widely consumed by adolescents and young adults. Almost all kinds of arrhythmias have been reported following EDs consumption, most of which is atrial fibrillation (AF). Atrial conduction time prolongation and heterogeneous sinusal impulses propagation to the atriums are the key electrophysiological mechanisms leading AF. We aimed to evaluate the acute effects of Red Bull ED ingestion on atrial electromechanical conduction times in healthy young adults. After a 12-hour fasting, 54 healthy young adults consumed 330 mL of Red Bull ED. Atrial electromechanical coupling (PA), intra-atrial electromechanical delay (intra-AEMD), and interatrial electromechanical delay (inter-AEMD) were measured at baseline and 2-hour after Red Bull ED ingestion by echocardiographic tissue-Doppler imaging (TDI) method. PA-lateral (49.7 +/- 11.2 vs 54.1 +/- 11.0 msn, p = 0.001) and PA-septal (40.8 +/- 9.1 vs 43.7 +/- 10.5 msn, p = 0.032) times were statistically significantly prolonged after Red Bull ED ingestion. There was also a statistically significant increase in the duration of inter-AEMD (14.4 +/- 10.6 vs 18.1 +/- 8.5 msn, p = 0.010) after ED ingestion. It was showed that even a single can of ED can acutely increase atrial electromechanical conduction times in young adults. These findings may be the cause of ED-associated AF. (C) 2019 Elsevier Inc.

Background The aim of this study was to investigate the association of plasma osmolality with all-cause mortality in ST-segment elevation myocardial infarction (STEMI) patients treated with a primary percutaneous coronary intervention. Methods This study included 3748 patients (mean age 58.3±11.8 years, men 81%) with STEMI treated with primary percutaneous coronary intervention. The following formula was used to measure the plasma osmolality at admission: osmolality=1.86×sodium (mmol/l)+glucose (mg/dl)/18+BUN (mg/dl)/2.8+9. Results The patients were followed up for a mean period of 22±10 months. Patients with higher plasma osmolality had 3.7 times higher in-hospital (95% confidence interval: 2.7-5.1) and 3.2 times higher long-term (95% confidence interval: 2.5-4.1) all-cause mortality rates than patients with lower plasma osmolality. Conclusion Plasma osmolality was found to be a predictor of both in-hospital and long-term all-cause mortality. Hence, plasma osmolality can be used to detect high-risk patients in STEMI.

Background The aim of this study was to investigate the association of the coronary thrombus burden with all-cause mortality and major adverse cardiac events (MACE) in ST-segment elevation myocardial infarction (STEMI) patients treated with 'in-cath lab' (downstream) high-dose bolus tirofiban. Methods This study included 2452 patients with STEMI treated with a primary percutaneous coronary intervention. All glycoprotein IIb/IIIa receptor inhibitor (GPI) (tirofiban) infusions were started in the catheterization laboratory according to the coronary thrombus burden; tirofiban was not administered to patients who did not have coronary thrombus burden. All patients with small, moderate, or large thrombus burden received tirofiban therapy. The primary study endpoint was the incidence of all-cause mortality. The secondary study endpoints were major bleeding and MACE, which included all-cause death, nonfatal acute coronary syndrome, and target lesion revascularization. Results The patients were followed up for a mean period of 28.3±10.4 months. The groups showed similar in-hospital and long-term event rates (MACE, major bleeding, and all-cause mortality). The 3-year Kaplan-Meier overall survivals for no thrombus, small thrombus, moderate thrombus, and large thrombus were 91.9, 92.6, 92.3, and 89.5%, respectively. Conclusion Despite the fact that the large coronary thrombus was found to be a predictor of MACE and mortality in many previous studies, we found that the large thrombus was not associated with MACE or in-hospital mortality or long-term mortality. This can be an effect of downstream GPI therapy. We suggest the use of downstream GPI therapy for STEMI patients with large coronary thrombus without an increased risk of bleeding.

Current studies evaluating the effect of serum potassium levels on mortality in patients with ST elevation myocardial infarction (STEMI) are lacking. We analyzed retrospectively 3760 patients diagnosed with STEMI. Mean serum potassium levels were categorized accordingly

Background: Atrial fibrillation (AF) is a common complication of ST-segment elevation myocardial infarction (STEMI), and AF might require anticoagulant treatment in some conditions. Study Question: There are no clear recommendations about vitamin K antagonist (VKA) use in patients with STEMI who complicated with new-onset transient AF. In this study, we examined the association of concomitant use of VKA and dual antiplatelet therapy (DAPT) with clinical outcomes of this patient population. Study Design: A total of 4086 patients with STEMI who underwent primary percutaneous coronary intervention retrospectively investigated. Among these patients, a total of 286 patients who developed new-onset transient AF during hospitalization were enrolled. VKA group consisted of 116 patients treated with warfarin, aspirin, and clopidogrel, and DAPT group consisted of 170 patients treated with aspirin and clopidogrel. Measures and Outcomes: One-year mortality, ischemic stroke, major, and minor bleeding were determined as clinical outcomes. Results: Although VKA group had proportionally lower mortality (17.2% vs. 20.0%) and ischemic stroke (7.8% vs. 11.8%) compared with DAPT group, the differences did not reach to statistical significance, whereas the 1-year major bleeding had higher rates at VKA group and that had 3.5-times higher major bleeding than DAPT group. This relationship was persisted after multivariable analysis (hazard ratio = 3.37, 95% CI, 1.76-10.04, P = 0.012). Conclusions: There is not a widely accepted treatment algorithm in patients with STEMI who complicated with new-onset AF in clinical guidelines. The current study indicated that transient form of new-onset AF might not require long-term VKA. Besides, addition of VKA to DAPT therapy may increase the rates of major and minor bleeding.

WOS: 000446494100008 PubMed: 30024398 Clomiphene citrate is a drug that stimulates ovulation and is commonly used in cases of female infertility. Generally, it is recognized as a safe agent for ovulation induction, but rarely, it is associated with life-threatening conditions. A 36-year-old woman who had been prescribed clomiphene citrate for infertility was admitted to the emergency department for chest pain lasting for 2 hours. She had no history of smoking, and she did not have any cardiac risk factor for myocardial infarction (MI). An electrocardiogram performed on admission revealed ST-elevation in the precordial leads. She was taken to the catheter laboratory for ST-elevation myocardial infarction, and the coronary angiography revealed total occlusion of the midportion of the left anterior descending artery (LAD) with a heavy thrombus burden. The circumflex and right coronary arteries were normal. After balloon dilatation, a 2.75x15-mm drug eluting stent was implanted in the mid part of the LAD. The patient had an uncomplicated recovery. Before discharge, echocardiography revealed apical akinesis; anterior and lateral hypokinesis; and an ejection fraction of 45% with mild mitral regurgitation. Although clomiphene citrate is a relatively safe drug for ovarian stimulation, it has been associated with serious side effects, such as MI. Physicians should be aware of the potential risks of clomiphene citrate, especially in patients with risk factors for coronary artery disease.

kaya, adnan/0000-0002-9225-8353 WOS: 000489002900007 PubMed: 30179288 Background Bronchial asthma may lead to pulmonary hypertension, right ventricular (RV) dysfunction, and cor pulmonale due to elevated afterload on the RV later in life. The aim of this study was to determine whether serum N-terminal pro-B-type natriuretic peptide (NT-proBNP) might serve as a biomarker for detecting subclinical RV dysfunction using echocardiography during the early stages of bronchial asthma. Methods Sixty-eight pediatric patients with asthma (asthma group) and 69 age- and sex-matched healthy children (control group) were enrolled. The study was conducted in a tertiary woman and child diseases education and research hospital from January 2013 to December 2013. RV function (2-D and tissue-Doppler echocardiography), pulmonary function (spirometry) and serum NT-proBNP concentration were evaluated. Results Mean age was 10.5 +/- 2.8 years in the asthma group and 10.2 +/- 2.7 years in the control group (P = 0.522). RV diastolic function was significantly decreased in the asthma group (ratio of tricuspid lateral annular early diastolic peak velocity to tricuspid lateral annular late diastolic peak velocity [E '/A '], 1.29 +/- 0.68 vs 1.74 +/- 0.89, P = 0.001). RV myocardial performance index was significantly higher in the asthma group than in the control group (0.28 +/- 0.06 vs 0.24 +/- 0.07, respectively; P = 0.003). Finally, serum NT-proBNP concentration was significantly higher in the asthma group than in the control group (292.3 +/- 142.2 pg/mL vs 208.2 +/- 70.1 pg/mL, respectively; P = 0.003). Conclusion Increased serum NT-proBNP is associated with subclinical RV dysfunction in asthmatic children. RV function is significantly affected in children with bronchial asthma.

Guvenc, Tolga Sinan/0000-0002-6738-266X; Keskin, Muhammed/0000-0002-4938-0097 WOS: 000459619200005 PubMed: 29475415 Background: The prognostic value of thrombolysis in myocardial infarction (TIMI) risk index (TRI) has been reported in patients with coronary artery disease. In this study, we evaluated the additional prognostic value of blood urea nitrogen (BUN) level to the TRI in patients with ST-segment elevation myocardial infarction (STEMI). Methods: We evaluated the in-hospital and long-term (3-year) prognostic value of modified TRI (mTRI) in patients with STEMI. The mTRI is calculated using the following equation; mTRI = (TRI x BUN)/10. Patients were stratified into 5 groups according to 20-point increments of mTRI. Results: The patients with higher mTRI had significantly higher in-hospital and long-term mortality. The risk for in-hospital and long-term mortality was highest for those within the Q5 (36.8 and 42.3%, respectively) and it was significantly higher than all the other groups (p < .001 for both). Conclusions: In this study, the prognostic value of TRI has been augmented by multiplication of TRI with BUN/10. Therefore, we present a pilot study of association of mTRI with overall STEMI patients.

Background Early diagnosis and identification of high-risk non-ST elevation myocardial infarction (NSTEMI) is an important issue. Fragmented QRS (fQRS) complexes are defined as various RSR’ patterns on 12-lead resting electrocardiography (ECG). Previous studies revealed that fQRS is related with increased ventricular arrhythmias and cardiovascular mortality. The relation between fQRS and mortality in acute coronary syndromes, mitral valve disease severity and structural heart disease has been shown in different studies. The aim of this study was to investigate relation between fQRS and long-term cardiovascular mortality in NSTEMI patients. Methods Patients who admitted to our emergency unit and diagnosed NSTEMI between 2012 and 2013, 433 patients were included prospectively. fQRS complexes determined in 85 patients. Patients were divided into two groups according to fQRS existence. All patients evaluated for their clinical, laboratory, electrocardiographic, and echocardiographic characteristics. Angiographic features of 315 patients who underwent coronary angiography was also recorded. In-hospital, 30-day and 12-month mortality was compared between these groups. Results Demographic characteristics and cardiovascular risk factors were similar in both groups except hyperlipidemia. GRACE risk score was higher in patients with fQRS and positively correlated with existence of fQRS. In hospital and 30-days mortality were similar but late mortality was higher in fQRS group. Predictors of late mortality were found to be age, heart rate, male sex in addition to fQRS. CONCLUSION We found a relation between fQRS and late mortality. Fragmented QRS may be seen as a cautionary signal for extensive myocardial damage and thereby increased long-term mortality for patients with NSTEMI.

Acute dyspnea is a major complaint of patients admitted to cardiology and emergency departments (ED). Acute dyspnea can be life-threatening, and is seen in cases of asthma, pulmonary embolism, acute heart failure and myocardial infarction. The present case is that of a 32-year-old man admitted to the ED with orthopnea position and agitation. Physical examination, electrocardiogram (ECG), transthoracic echocardiogram (TTE), contrast-enhanced computed tomography (CECT) of thorax and coronary angiography (CAG) helped to rule out chest disease pathologies such as pneuomo-thorax, pulmonary embolism and coronary artery disease, but were not enough to make an appropriate diagnosis in this case. Because of high pretest probability of aortic dissection, transesophageal echocardiography (TEE) was performed and a diagnosis of Stanford type A dissection closing left main coronary artery (LMCA) ostia from beat to beat was made.

WOS: 000433094100005 PubMed ID: 29607427 OBJECTIVE: This study aimed to determine the relationship between the diameter of coronary artery stents and age, gender, diabetes mellitus (DM), left ventricular ejection fraction (LVEF), renal dysfunction, and the clinical presentation of myocardial ischemia in the cohort of patients with implanted stents in coronary arteries with severe stenotic lesions. METHODS: This study included 2256 patients (mean age, 59.3 +/- 10.9 years; men, 62%) who underwent percutaneous coronary intervention (PCI). The clinical status of the patients at presentation was subcategorized as follows: ST-segment elevation myocardial infarction, non-ST segment elevation myocardial infarction, unstable angina pectoris, and stable angina pectoris. The diameters, without any type or brand differentiation, were divided into two groups as follows: Group I, which included 2.5-and 2.75-mm-diameter stents, and Group II, which included >= 3-mm-diameter stents. RESULTS: The type of procedure, including primary PCI, early invasive strategy, and elective stenting, was not found to be a significant factor affecting the diameter of coronary artery stents. Univariate and multivariate analyses revealed a relationship between the diameter of coronary artery stents and age, gender, DM, and LVEF. CONCLUSION: This study demonstrated that the diameter of coronary artery stents was independently associated with gender, age, a history of DM, and moderate-to-severe systolic left ventricular dysfunction.

Background: Atrial fibrillation is the most common clinically significant arrhythmia. It is now established that atrial high-rate episodes are highly correlated with atrial fibrillation. Aims: To investigate the relation between diastolic electrocardiographic parameters and subclinical atrial fibrillation detected by cardiac implantable electronic devices. Study Design: Ccross-sectional study. Methods: A total of 203 patients who had a dual-chamber, rate-modulated pacing pacemaker implanted due to sinus node dysfunction were prospectively enrolled in this study. Atrial high-rate episodes were defined as any lasting more than 5 min with an atrial rate of ≥220 beats per minute during the previous year. Patient groups were categorized on the basis of pacemaker interrogation as the absence of atrial high-rate episodes [atrial high-rate episodes (-)] and the presence of atrial high-rate episodes [atrial high-rate episodes (+)]. Episodes related to atrial over sensing were excluded. Twelve-lead surface electrocardiography was independently analyzed by two experienced readers for the measurement of diastolic electrocardiography parameters. Results: Among 203 patients (mean age: 67.5±9.1, 60.1% male), 51 (25.1%) with atrial high-rate episodes were defined as group 1 and 152 (74.9%) without atrial high-rate episodes were defined as group 2. Both groups were similar in terms of demographic characteristics and cardiovascular risk factors. Tend-Q and Tend-P were significantly longer in group 2. PQ interval was statistically longer in group 1. Corrected QT interval was significantly longer in group 1. Diastolic electrocardiography index, heart rate and PQ and QT intervals were the only independent predictors of atrial high-rate episodes in patients with dual pacemakers in multivariate analysis. Conclusion: Abnormal diastolic electrocardiography parameters are powerful predisposing factors for the initiation of incident atrial fibrillation. Diastolic electrocardiography parameters and a novel diastolic index predict atrial high-rate episodes. Evaluating these parameters enables clinicians to identify patients who are at high risk and who may benefit from prophylactic treatment.

Guvenc, Tolga Sinan/0000-0002-6738-266X; Keskin, Muhammed/0000-0002-4938-0097 WOS: 000405144700024 PubMed: 28479168 Left ventricular diastolic dysfunction (LVDD) has been relatively less studied than other cardiac changes during pregnancy. Previous studies revealed a mild diastolic deterioration during pregnancy. However, these studies did not evaluate the long-term effect of parity on left ventricular diastolic function. A comprehensive study evaluating the long-term effect of parity on diastolic function is required. A total of 710 women with various number of parity were evaluated through echocardiography to reveal the status of diastolic function. Echo cardiographic parameters were compared among the women by parity number and categorized accordingly: none, 0 to 4 and 4< parity (grand multiparous). In nulliparous group, 19 women (23.2%) had grade 1 LVDD, and only 2 women (2.4%) had grade 2 LVDD. In women with a parity number of 0 to 4, 209 women (38.3%) had grade 1 LVDD, and only 17 women (3.1%) had grade 2 LVDD. In grand multiparous group, only 2 women (2.4%) did not have LVDD, and 12 women (14.6%) had grade 2 LVDD. None of the subjects had grade 3 or grade 4 LVDD. According to hierarchical logistic regression analysis, any grade of LVDD and grade 2 LVDD had the highest rates at parity category of > 4 parity and that had 21 and 5.8 times higher than nulliparous group, respectively. In conclusion, according to the present study, grand multiparity but not multiparity, severely deteriorates left ventricular diastolic function. Further studies are warranted to evaluate the risk of gradual diastolic dysfunction after each pregnancy. (C) 2017 Elsevier Inc. All rights reserved.

Background: Concomitant thyroid and heart disease are frequently encountered in clinical practice. There are many studies evaluating thyroid function in acute and critical conditions. Information on thyroid dysfunction in ST-segment elevation myocardial infarction (STEMI) is limited; its correlation with short and long-term outcome is not fully known. Methods: Four hundred and fifty seven patients diagnosed with STEMI in our emergency department were included in the study. Patients were divided into two groups: patients with normal thyroid function (euthyroid) and patients with thyroid dysfunction. STEMI was diagnosed with 12 derivation surface electrocardiogram. Thyroid hormone levels (TSH, free T3 and free T4) were measured. Patients with other acute coronary syndromes and endocrine pathologies except diabetes mellitus were excluded. Two patient groups were compared in terms of in-hospital and long-term outcome. Results: Out of 457, 72 (15%) patients with thyroid dysfunction were detected. The other patients were euthyroid and constituted the control group. In-hospital cardiogenic shock (15% vs. 3% in the control group; p < 0.01) and death (7% vs. 1% in the control group; p < 0.01) were more frequently observed in the thyroid dysfunction group. In the subgroup analysis, it was observed that patients with sick euthyroid syndrome have the poorest outcome. Other markers for poor outcome were anemia and renal failure. Conclusions: Thyroid dysfunction, particularly sick euthyroid syndrome, was found to be related to in-hospital and long term mortality in patients with STEMI undergoing primary percutaneous intervention.

Background The effectiveness of primary percutaneous coronary intervention (PCI) in ST segment elevation myocardial infarction (STEMI) is well established. The clinical variables associated with poor prognosis in patients with STEMI have been extensively investigated. Right coronary artery (RCA) has two anatomical variations detected on coronary angiography namely C-shaped and sigma shaped RCA. The clinical importance of the shape of RCA in patients with STEMI has not been investigated before. Purpose To investigate the prognostic value of RCA shape in patients with inferior STEMI treated with primary PCI. Methods Angiographic data of patients with inferior STEMI who were treated with primary PCI were retrospectively recruited. The differentiation of sigma and C-shaped RCAs was shown using single-frame angiograms, obtained during end-diastole of cardiac cycle in the left anterior oblique projection at 25° to 35° with no cranio-caudal angulation. Cardiovascular events at 30-days and on follow up were obtained through review of hospital records and telephone contact with the patient or the patient's relatives. Patients with C-shaped RCAs served as the control group. Results A total number of 824 patients with inferior STEMI who were treated with primary PCI for RCA were included. Sigma shaped RCA was observed in 15.1% of the subjects. In the sigma shaped RCA group, the door-to-balloon times were longer (32.5 ± 5.1 vs. 27.8 ± 4.6 min; P = 0.01) and TIMI 3 flow restoration rates were lower (76.8% vs. 94.1%; p=0.01) compared to the controls. Mean SYNTAX scores were significantly higher in patients with sigma shaped RCA. Four patients (3.2%) in the sigma shaped RCA group and 23 patients (3.3%) in the control group died by day 30. The incidence of stent thrombosis, recurrent MI, and target lesion revascularization, were similar between the groups. During the follow-up (mean 37.6 ± 13.4 months) 15 patients (12.3%) from the sigma shaped RCA group and 28 (4.1%) patients from the control group died (P = 0.01). The incidence of recurrent MI (27.2% vs. 13.7%; P = 0.01) and major adverse cardiovascular events (29.7% vs. 16.3%; P = 0.01) were significantly higher in the sigma shaped RCA group. In multivariate analysis, age, Killip class of >1, the presence of sigma shaped RCA, post PCI TIMI flow

Recently, the presence of left ventricular clefts has been identified frequently with the advancement of cardiac imaging modalities such as cardiac magnetic resonance imaging and computed tomography. Here we report a rare case of left ventricular cleft that was incidentally diagnosed with the ECG changes that imitated the presence of LMCA stenosis and diagnosed by transthoracic echocardiography in a patient with autosomal dominant polycytic kidney disease.

Cardiac resynchronization therapy with an implantable cardioverter-defibrillator (CRT-D) is the preferred treatment for patients with severe heart failure, dyssynchrony, and an increased risk of sudden cardiac death or for primary ventricular arrhythmia survivors. Rarely, left ventricular epicardial pacing can induce ventricular tachyarrhythmia rather than a beneficial effect. We describe an ischemic cardiomyopathy patient who underwent CRT-D therapy and developed sustained torsades de pointes (TdP) immediately after switching to biventricular pacing (BVP) mode. Here, TdP possibly developed owing to the change in the dispersion of repolarization of the left ventricle myocardium. The diagnosis and management of BVP-induced ventricular arrhythmia is discussed.

The aim of the present study was to investigate the effect of adjunctive TA during PPCI on clinical outcomes in patients with ST-segment elevation myocardial infarction (STEMI) and a large thrombus. We assessed the effect of adjunctive TA on in-hospital and 3-year clinical outcomes in 627 patients with STEMI and a large thrombus in the native coronary artery. The cumulative 3-year incidence of all-cause death was not significantly different between the 2 groups (91.5% vs 89.0%, log-rank test p = 0.347). After adjusting for confounders, the risk of all-cause death in the TA group was not significantly lower than that in the non-TA group (hazard ratio 1.11, 95% confidence interval 0.60 to 3.54, p = 0.674). The adjusted risks of target lesion revascularization, nonfatal acute myocardial infarction, and stent thrombosis were also not significantly different between the 2 groups. In conclusion, adjunctive TA during PPCI was not associated with better in-hospital and 3-year all-cause deaths in patients with STEMI and a large coronary artery thrombus. (C) 2017 Elsevier Inc.

Recent studies have implied a prognostic value of the prognostic nutritional index (PNI) in colorectal surgeries and postoperative septic complications. The present study aimed to evaluate the prognostic value of PNI in ST-segment elevation myocardial infarction (STEMI) patients. Methods and results: We evaluated the in-hospital and long-term (3 years) prognostic impact of PNI on 1823 patients with STEMI undergoing primary percutaneous coronary intervention. Patients with lower PNI had significantly higher in-hospital and long-term mortality and major adverse cardiac events. After adjustment for all confounders, the in-hospital mortality rates were 7.9 times higher at the lower PNI level (95% CI: 5.0-15.8) than those at the higher PNI level. The long-term mortality rates were also 6.4 times higher at the lower PNI level (95% CI: 4.4-12.4) than those at the higher PNI level. Conclusion: The present study demonstrated that the PNI, calculated based on the serum albumin level and lymphocyte count, is an independent prognostic factor for mortality in patients with STEMI.

Summary– Anticoagulation with warfarin is the main treatment of intracardiac thrombus. While novel oral anticoagulants (NOACs) have been approved by the US Food and Drug Administration (FDA) for stroke prevention in patients with nonvalvular atrial fibrillation (AF), they are not indicated for resolution of intracardiac thrombus. The case of a 60-year-old woman with left ventricular (LV) thrombus secondary to hypertrophic cardiomyopathy and AF is described in the present report. Indications for oral anticoagulation were AF and LV thrombus. Thrombus was dissolved after 1 month of apixaban treatment. To the best of our knowledge, this is the first report that describes the resolution of LV thrombus with apixaban treatment in a patient with hypertrophic cardiomyopathy.

Thromboangitis obliterans (TAO), also known as Buerger’s disease (BD), is a non-atherosclerotic, segmental, inflammatory, episodic, non-destructive, thrombotic, and occlusive disease of unknown origin compromising small to medium-sized distal arteries, veins, and nerves (1). Intravenous iloprost (2), intermittent pneumatic compression (3), bosentan (4), and cilostazol (5) are used or experimental medical therapies for TAO, for all that smoking cessation is the sole definitive therapy. Surgical revascularization is usually not preferred because of high involvement of distal segments of vessels. Endovascular revascularization could be an option for patients with bad distal vasculature. Case Report

Objective: This study attempted to fill the gaps in evidence related to response to clopidogrel treatment in the Turkish population. The study aimed to determine the prevalence, associated risk factors, and clinical outcomes of high on-treatment platelet reactivity (HTPR) of clopidogrel in patients undergoing percutaneous coronary intervention (PCI) in a tertiary cardiovascular hospital in Turkey. Methods: In this prospective studied a total of 1.238 patients undergoing PCI were included in the present study. Blood samples were analyzed using a Multiplate analyzer. All patients were examined in the outpatient clinics at the end of the first and sixth months for recording drug therapy compliance and study endpoints. Results: Among the study population, 324 (30.2%) patients were found to have HTPR (mean age 58.03±11.88 years, 71.7% men). The incidence of HTPR was higher amongst females than amongst males (38.3% vs. 27%, p=0.010). Hypertension and diabetes mellitus were more frequently observed in the HTPR group (57.7% vs. 48.7%, p=0.004; 35% vs. 29.1%, p=0.040, respectively). When the recorded data were analyzed using multinomial regression analysis, hypertension, hemoglobin level, platelet, lymphocyte, and eosinophil count were independently associated with HTPR. Conclusion: On the basis of the results obtained from our study, we conclude that 30.2% of the Turkish population has HTPR. Our results also led us to believe that hypertension is an associated risk factor and decreased hemoglobin level as well as increased platelet counts are laboratory parameters that are strongly associated with the presence of HTPR. However, no differences were observed with regard to cardiovascular mortality and stent thrombosis. (Anatol J Cardiol 2016; 16: 967-73)

Fabry disease is the second most common inherited (X-linked recessive) lysosomal storage disease associated with multiple organ involvement. Cardiac involvement of Fabry disease varies. Successful radiofrequency ablation of a Fabry disease patient with Wolff-Parkinson- White syndrome and left ventricular noncompaction is described in the present report.

WOS: 000461045000001 PubMed: 30857397 Inflammation has been implicated in the pathogenesis of endothelial dysfunction, atherosclerosis, and microvascular coronary dysfunction. In this context, it is thought that fibrinogen, high-sensitive C-reactive protein (hsCRP), and albumin may be associated with the pathogenesis of coronary slow flow (CSF). We aimed to evaluate the ratios of fibrinogen-to-albumin and hsCRP-to-albumin in patients with CSF compared to patients with angiographically normal coronary arteries and stable coronary artery disease (CAD). In all, 65 patients with CSF, 65 patients with newly diagnosed stable CAD, and 65 control participants with angiographically normal coronary arteries were included. The coronary flow rates of all patients were determined by the Thrombolysis in Myocardial Infarction frame count method. Fibrinogen, hsCRP, and albumin levels were analyzed in all patients, and the fibrinogen-to-albumin and hsCRP-to-albumin ratios were calculated. The baseline characteristics of the 3 groups were similar. The plasma albumin level was significantly lower, whereas the fibrinogen and the hsCRP levels were significantly higher, in the CSF and CAD groups compared to the controls. The fibrinogen-to-albumin and hsCRP-to-albumin ratios were significantly higher in both the CSF and the CAD groups compared to the control group. The hsCRP-to-albumin ratio was positively correlated with the mean Thrombolysis in Myocardial Infarction frame count in the whole study population. According to the receiver-operating characteristic analysis, the efficacies of the fibrinogen-to-albumin and hsCRP-to-albumin ratios in predicting CSF were significant. The fibrinogen-to-albumin and hsCRP-to-albumin ratios, which were increased by a reciprocal change, suggest that inflammation may play a role in the pathogenesis of CSF.

Objectives: Previous studies have shown the association between various hematological parameters and cardiovascular diseases, and their prognostic value. In this study, we compared red cell distribution width (RDW), neutrophil lymphocyte ratio (NLR) and mean platelet volume (MPV) measurements among patients with poor coronary collateral circulation (CCC) and well-developed CCC. Study design: 326 patients with stable coronary artery disease (CAD) were evaluated retrospectively. CCC was graded by using the Rentrop classification. The poor CCC group included patients with Rentrop 0-1 CCC, and the good CCC group included Rentrop 2-3 CCC. Results: There were 171 subjects (84% male; mean age 56.6+-10.4 years) in the poor CCC group, and 155 subjects (89% male; mean age 57.6+-9.7 years) in the good CCC group. The total number of vessels with >95% stenosis (1.1+-0.5 vs. 1.0+-0.4; p=0.64) and Gensini scores (84.4+-38.8 vs. 83.3+-37.4; p=0.83) was not higher in the poor CCC group compared to the good CCC group. RDW was significantly higher in the poor CCC group compared to the good CCC group (14.19+-1.36% vs. 13.89+-1.19%; p=0.04). In multivariate logistic regression analysis, elevated levels of RDW and LDL were found to be independent predictors of poor CCC (OR 1.73, 95% CI: 1.30-2.29, p=0.01 and OR 1.01 95% CI 1.002-1.02; p=0.02, respectively). Conclusion: In the present study, poor CCC was found to be independently correlated with RDW, but not with any other hematological parameters in patients with stable CAD.

Behçet's disease (BD) is a multisystem vasculitis that may involve vessels of all sizes. Acute coronary syndrome (ACS) due to secondary involvement of BD is rare and its management less clear. In this case, a 29-year-old man admitted to the emergency room with ongoing chest pain was interned to the coronary care unit with a diagnosis of ACS. The patient had been diagnosed 1 year before with BD and had been without regular follow-up, despite the suggested use of cholchium. An immediate coronary angiography revealed a fresh thrombus image in the proximal segment of the right coronary artery (RCA), an aneurysm of the left anterior descending artery (LAD) at proximal segment, and a hemodynamically significant lesion following the aneurysm. Intervention was ended because of normal flow (TIMI III) of distal RCA. An intravenous infusion of glycoprotein IIb/ IIIa receptor inhibitor (tirofiban) was administered, and a control angiography showed dissolution of a thrombus in RCA, but enlarged aneurysm of LAD and a new aneurysm in RCA.
