The relationship between QRS-T angle and left ventricular global longitudinal strain in prehypertensive patients.

BACKGROUND AND AIM: This study aims to examine the relationship between the QRS-T angle (QRS-Ta) detected on electrocardiography and left ventricular global longitudinal strain (LV-GLS) calculated on echocardiography in prehypertensive patients. MATERIALS AND METHODS: A total of 300 patients were included in our study, and the median value of QRS-Ta of the entire population was 27.The patients were divided into two groups (supramedian 148 patients, inframedian 152 patients) according to the median value. Statistical analysis was performed between the two groups. RESULTS: LV-GLS was lower in the supramedian QRS-Ta group [20 (16-26) vs. 21 (16-27); p < 0.001]. A statistical difference was found between the two groups in age (p < 0.001), BMI (p < 0.001), Hs-troponin I (p < 0.001), aortic velocity (p = 0.023) and TAPSE (p = 0.005) parameters except for LV-GLS.The correlation between QRS-Ta and LV-GLS was determined by Spearman's correlation test (p < 0.001).In the multivariable logistic regression analysis model, LV-GLS (OR: 0.365, 95%CI 0.171-0.780, p = 0.009) was one of the independent predictors for increased QRS-Ta. Others were determined as age (p < 0.001) and TAPSE (p = 0.015). CONCLUSIONS: In this study, a strong relationship was found between QRS-Ta, which is easily calculated by ECG, and LV-GLS, which is an advanced echocardiographic examination, in prehypertensive patients.

Clinical outcomes of the Myval transcatheter heart valve system in patients with severe aortic valve stenosis: a two-year follow-up observational study.

Introduction: Limited data exist on long-term follow-up of severe aortic stenosis (SAS) patients who have undergone transcatheter aortic valve implantation (TAVI) with a new generation, balloon expandable Myval transcatheter heart valve (THV). Thus, we sought to investigate the performance and 2-year clinical outcome of the Myval THV system based on Valve Academic Research Consortium-3 (VARC-3) criteria. Material and methods: A multi-centre, registry-based, observational study was conducted, which included 207 consecutive degenerative SAS patients, from Turkey (n = 128), Italy (n = 58), and Greece (n = 21) (mean [standard deviation] 81 (7) years, 94 [45%] men; 73% NYHA III or IV; EuroSCORE II 5.2% [2.4%]); all patients underwent TAVI with Myval. Patients were followed up at 1 year and 2 years after implantation. Clinical and procedural outcomes were defined according to VARC-3 criteria. Results: Technical success was observed in 204 (99%), device success was observed in 189 (91%), early safety was observed in 161 (78%), and clinical efficacy was observed in 163 (79%) patients. The 30-day death rate was 7.7%; of these, 3.4% were due to cardiovascular reasons. All-cause and cardiovascular mortality rates were 9.7% and 4.3% at 1-year follow-up, and 17.4% and 9.7% at 2-year follow-up, respectively. Incidence of ≥ moderate paravalvular leak (PVL) at 30 days, 1 year and 2 years of follow-up were 3.4%, 4.3% and 4.8%. A total of 11.1% of patients required a permanent pacemaker implantation (PPI) at 30 days after implantation, while the cumulative rate of PPI at 2 years was 12.1%. Conclusions: In this cohort of patients with SAS, the Myval was found to be safe and effective in up to 2 years of follow-up.

Can HALP score predict post-contrast acute kidney injury and 6-year mortality in patients undergoing endovascular abdominal aneurysm repair?

BACKGROUND: The aim of this study is to investigate the relationship between HALP score and post-contrast acute kidney injury (PC-AKI) and average 6-year mortality in patients undergoing endovascular abdominal aortic aneurysm repair (EVAR). METHODS: 125 patients who underwent EVAR between January 2015 and December 2020 were included in our study. HALP score was calculated with the formula "hemoglobin × albumin × lymphocyte count/platelet count." In the first phase of the study, two groups were developed: those who developed PC-AKI and those who did not. In the second stage, statistical analysis was performed by creating two groups: average 6-year mortality and survivors group. RESULTS: HALP score was found to be lower in the PC-AKI group [26.12 (14-61.54) versus 40.53 (7.22-103.61); p < .001]. Low HALP score was found to be both a dependent and independent predictor of the development of PC-AKI (p = .019). HALP score was also found to be lower in the mortality group compared to the survivors [28.97 (12.6-103.61) versus 40.81 (7.22-99) p = .004]. Low HALP score was found to be only a dependent predictor of mortality. The development of PC-AKI was found to be an independent predictor of mortality (p = .042). CONCLUSIONS: The HALP score, which can be calculated with a simple formula, can be used to predict PC-AKI and medium-long-term mortality in EVAR patients.

Non-Alcoholic Fatty Pancreas Disease is Associated with SYNTAX Score in Acute Coronary Syndrome.

Background: Evidence that individuals with excess fat in the pancreas have an increased risk of cardiovascular disease has been growing recently. Risk evaluation in acute coronary syndrome (ACS) patients plays a crucial role for both prognosis prediction and decision-making. Aim: The main aim of this study was to investigate the relationship between non-alcoholic fatty pancreas disease (NAFPD) and the complexity and severity of coronary artery disease as assessed using the SYNTAX score (SXscore) in ACS patients. Methods: A total of 99 consecutive patients with a first-time diagnosis of ACS were recruited. NAFPD was evaluated using transabdominal ultrasonography (TUS). SXscore was calculated using the SXscore algorithm. Results: The patients with NAFPD had a significantly higher SXscore than those without NAFPD (12.3 ± 6.4 and 8.2 ± 4.3, p < 0.001). Univariable analysis showed that hypertension (p = 0.033) and presence of NAFPD (p = 0.001) were associated with increased SXscore. Moreover, multivariable analysis showed that the presence of NAFPD (p = 0.002) was associated with increased SXscore. Conclusions: NAFPD is easily detected by TUS. The presence of NAFPD in ACS patients may be a warning signal of complexity and severity of coronary artery disease.

Abnormal Circadian Blood Pressure Variation is Associated with SYNTAX Scores in Hospitalized Patients with Acute Coronary Syndrome. / A Variação Anormal da Pressão Arterial Circadiana está Associada aos Escores SYNTAX em Pacientes Hospitalizados com Síndrome Coronariana Aguda.

BACKGROUND: Blunted nocturnal blood pressure (BP) reduction, referred to as non-dipper hypertension, is a strong predictor of cardiovascular morbidity and mortality. OBJECTIVES: This study aimed to investigate the relationship between non-dipper hypertension and the severity and complexity of coronary artery disease using SYNTAX score in hospitalized patients with acute coronary syndrome. METHODS: A total of 306 consecutive patients with acute coronary syndrome were screened. Patients who were clinically stable and admitted to the intermediate intensive care unit at least 24 hours after angiography and/or successful revascularization. After the exclusion criteria, 141 patients (34 female and 107 male; mean age 61 ± 11 years) were included. Non-dipper hypertension has been defined as a 0% to 10% decrease in average systolic BP at nighttime compared to daytime, measured at hourly intervals using the same automatic BP measuring device on bedside monitors (Vismo PVM-2701; Nihon Kohden Corp., Tokyo, Japan). SYNTAX score was calculated with an online calculator. The independent predictors of SYNTAX score were assessed using multivariable logistic regression analysis. P < 0.05 was considered statistically significant. RESULTS: The patients with non-dipper hypertension had higher SYNTAX score than the patients with dipper hypertension (11.12 ± 6.41 versus 6.74 ± 6.45, p < 0.0001). In a multivariable logistic regression model, non-dipper hypertension status (odds ratio: 5.159; 95% confidence interval: 2.246 to 11.852, p < 0.001), sex (p = 0.012) and low-density lipoprotein cholesterol (p = 0.008) emerged as independent predictors of high SYNTAX score. CONCLUSIONS: The results of our study provide a possible additional mechanism linking abnormal circadian BP profile with coronary artery disease severity and complexity in patients with acute coronary syndrome.

FUNDAMENTO: Menor redução da pressão arterial (PA) noturna, conhecida como hipertensão não-dipper, é um forte preditor de morbimortalidade cardiovascular. OBJETIVOS: Este estudo visou investigar a relação entre a hipertensão não-dipper e a gravidade e complexidade da doença arterial coronariana usando o escore SYNTAX em pacientes hospitalizados com síndrome coronariana aguda. MÉTODOS: Foram selecionados 306 pacientes consecutivos com síndrome coronariana aguda. Pacientes clinicamente estáveis internados na unidade de terapia intensiva intermediária pelo menos 24 horas após a angiografia e/ou revascularização bem sucedida. Após os critérios de exclusão, foram incluídos 141 pacientes (34 mulheres e 107 homens; idade média 61 ± 11 anos). A hipertensão não-dipper foi definida como uma queda de 0% a 10% na PA sistólica média durante a noite em comparação com o dia, medida em intervalos de 1 hora, usando o mesmo dispositivo automático de medição de PA em monitores de beira de leito (Vismo PVM-2701; Nihon Kohden Corp., Tóquio, Japão). O escore SYNTAX foi calculado com uma calculadora online. Os preditores independentes do escore SYNTAX foram avaliados por meio de análise de regressão logística multivariada. P < 0,05 foi considerado estatisticamente significativo. RESULTADOS: Os pacientes com hipertensão não-dipper apresentaram escore SYNTAX maior do que os pacientes com hipertensão dipper (11,12 ± 6,41 versus 6,74 ± 6,45, p < 0,0001). Em um modelo de regressão logística multivariável, o status de hipertensão não dipper (odds ratio: 5,159; intervalo de confiança de 95%: 2,246 a 11,852, p < 0,001), sexo (p = 0,012) e colesterol de lipoproteína de baixa densidade (p = 0,008) emergiram como preditores independentes de alto escore SYNTAX. CONCLUSÕES: Os resultados do nosso estudo fornecem um possível mecanismo adicional ligando o perfil anormal da PA circadiana à gravidade e à complexidade da doença arterial coronariana em pacientes com síndrome coronariana aguda.

The Association Between Cardio-Ankle Vascular Index and Primary Idiopathic Complete Atrioventricular Block in an Elderly Population.

The most common cause of complete atrioventricular block (CAVB) is age-related fibrotic degeneration and is referred to as primary idiopathic complete atrioventricular block (iCAVB). This study aims to investigate the relationship between iCAVB and arterial stiffness using the cardio-ankle vascular index (CAVI).In this study, of 205 CAVB patients, 41 patients with iCAVB implanted with a dual-chamber permanent pacemaker and 40 age- and gender-matched controls were studied. Arterial stiffness was assessed by a VaSera VS-1000 CAVI instrument. The CAVI values of patients with iCAVB were significantly higher compared with the controls (9.63 ± 1.42 vs 8.57 ± 1.12, P < .001). Idiopathic complete atrioventricular block frequency was higher among patients with abnormal CAVI values than those with borderline and normal CAVI (P = .04). In multivariate analysis, only CAVI was an independent predictor of iCAVB after adjusting for other relevant factors (odds ratio, 2.575; 95% CI [1.390-4.770]; P = .003). The present study demonstrated that CAVI, as a marker of arterial stiffness, was increased among elderly patients with iCAVB. Thus, we provide a possible additional mechanism linking easily measured CAVI with iCAVB.

First experiences with a new balloon-expandable Myval transcatheter aortic valve: a preliminary study.

BACKGROUND: In the present article, we present our first experiences with a new type of balloon-expandable Myval valve (Meril Life Sciences, Gujarat, India). MATERIALS AND METHODS: A total of 25 consecutive patients who underwent transcatheter aortic valve implantation (TAVI) from June 2020 to November 2020 were included in the study. RESULTS: The mean age of the study population was 83 (75-87) years; 17 (68%) were female, and 20 (80%) had hypertension. The Society of Thoracic Surgeons (STS) score of the group was 5.4% ± 3.5%. TAVI was performed via the transfemoral route on all patients. In 19 (76%) cases, we started the procedure without predilation. In two (10.5%) cases performed without predilation, the prosthesis did not pass the native valve. We had to implant the valve from the descending aorta in one (4%) patient. We used Prostar XL (Abbott Vascular, Santa Clara, CA, USA) for six (24%) patients and ProGlide (Abbott Vascular) for 19 (76%) patients for vascular closure. Two (8%) in-hospital deaths occurred in our study but there were no deaths in the 30-day and 90-day follow-up. Vascular complications were observed in one (4%) patient. None of the patients in our study had severe paravalvular leak (PVL), while two (8%) patients had moderate PVL. A permanent pacemaker (PPM) was required in two (8%) patients for the indication of complete atrioventricular block. The mean hospital stay for the whole group was 4 (3-7) days. CONCLUSION: Based on our experiences, the new balloon-expandable valve Myval is easy to use, efficient, and has only a few negligible drawbacks such as the need for predilation of the sheath. While shaft flexibility may have advantages in some situations including in very tortuous arteries, it may cause some difficulties in alignment of the valves.

Left ventricular global longitudinal strain in low cardiac risk outpatients who recently recovered from coronavirus disease 2019.

The cardiac sequelae of coronavirus disease 2019 (COVID-19), a worldwide global pandemic, are still uncertain, particularly in the asymptomatic, low cardiac risk outpatient population. This study aims to evaluate the asymptomatic, low cardiac risk out-patient population who recently recovered from COVID-19, using 2-D left ventricular-global longitudinal strain (LV-GLS) proven to be capable of detecting subclinical myocardial injury. Out of 305 COVID-19 positive patients, 70 asymptomatic out-patients were determined as the study group and 70 age and sex-matched healthy adults as the control group. The echocardiographic examination was performed with the Philips IE33 system, and LV-GLS was measured using commercially available software QLAB 9 (cardiac motion quantification; Philips Medical Systems). The absolute value of LV-GLS ≤ 18 did deem to be impaired LV-GLS. The absolute value of LV-GLS was statistically significantly lower in the COVID-19 group than in healthy controls (19.17 ± 2.65 vs. 20.07 ± 2.19, p = 0.03). The correlation between having recovered from COVID-19 and impaired LV-GLS (≤18) did detect with the Pearson correlation test (p = 0.02). Having recovered from COVID-19 was found as a predictor for detecting impaired LV-GLS (≤18) in the multivariable logistic regression analysis (odds ratio, 0.133 (0.038-0.461); 95% CI, p = 0.001). This study suggests that COVID-19 may cause subclinical LV dysfunction detected by LV-GLS during early recovery even in a population of patients at low cardiac risk, asymptomatic, and recovered with home quarantine. The study findings indicate that the long-term cardiovascular follow-up of these patients may be more important than thought.

Abdominal Aortic Intima-Media Thickness Predicts Coronary Artery Disease Severity in Patients With Stable Angina Pectoris: A Prospective Study.

Accurately identifying coronary artery disease (CAD) is the key element in guiding the work-up of patients with suspected angina. Thickening of the arterial wall is a hallmark of atherosclerosis. Therefore, the main purpose of this study was to determine whether abdominal aortic intima-media thickness (AAIMT), which is the earliest zone of atherosclerotic manifestations, has a predictive value in CAD severity. A total of 255 consecutive patients who were referred for invasive coronary angiography due to suspected stable angina pectoris were prospectively included in the study. B-mode ultrasonography was used to determine AAIMT before coronary angiography. Coronary artery disease severity was assessed with the SYNTAX score (SS). A history of hypertension, age, dyslipidemia, and higher AAIMT (odds ratio: 2.570; 95%CI 1.831-3.608; P < .001) were independent predictors of intermediate or high SS. An AAIMT <1.3 mm had a negative predictive value of 98% for the presence of intermediate or high SS and 83% for obstructive CAD. In conclusion, AAIMT showed a significant and independent predictive value for intermediate or high SS. Therefore, AAIMT may be a noninvasive and useful tool for decision-making by cardiologists (eg, to use a more invasive approach).

Relation between fragmented QRS complex and cardio-ankle vascular index in asymptomatic subjects.

OBJECTIVES: Stiffness of large arteries has been related to cardiovascular mortality. Cardio-ankle vascular index (CAVI) is a novel marker of arterial stiffness. Herein, we aimed to study the relationship between fragmented QRS (fQRS) in electrocardiogram and CAVI. METHODS: Asymptomatic patients with fQRS and without fQRS were enrolled in the study consecutively. The fQRS complexes were analyzed in the 12-lead electrocardiogram. Arterial stiffness was assessed by using cardio ankle vascular index (CAVI). It was measured by a VaSera VS-1000 CAVI instrument. RESULTS: CAVI values of the patients with fQRS was significantly higher compared to those without fQRS (8.625 (7.9-9.2) versus 6.65 (6.7-8.4) p < .001). In a univariate analysis, it was revealed that there was a significant correlation between increased CAVI and fQRS, age, and epicardial fat thickness. Multiple binary logistic regression analysis revealed that age [95% confidence interval (CI): 1,068-1.214, p < .001] and fQRS [95% (CI): 1.766-23.117, p: 0.005] were the independent determinants of increased CAVI values. CONCLUSIONS: ECG is a widely and readily available, inexpensive, reproducible technique that can be examined by almost every physician. fQRS values in electrocardiogram may provide a significant predictive value for arterial stiffness in asymptomatic subjects.

Relation of p - wave dispersion with presystolic a - wave and aortic valve sclerosis in asymptomatic subjects.

BACKGROUND: P-wave duration and P-wave dispersion (PWD) are thought to be the surrogate marker of devoloping atrial fibrillation (AF). The main purpose of present study was to investigate the association between presystolic wave (PSW), aortic valve sclerosis, and PWD. PATIENTS AND METHODS: Patients with sinus rhythm admitted to the cardiology outpatient clinic were consecutively enrolled. Maximum (Pmax) and minimum (Pmin) P-wave duration and PWD were measured. Echocardiography was used to assess the aortic valve morphology and presence of PSW. The patients were divided into two groups according to presence or absence of AVSc and PSW. RESULTS: A total of 100 patients were enrolled consecutively. Patients with both PSW and AVSc had higher PWD values compared with those without PSW (42 ± 15 vs 65 ± 20) and AVSc (52 ± 21 vs 69 ± 19). The patients were categorized on the basis of median PWD values. According to univariate analysis, there was significant association between PWD and presence of PSW (P: .004), presence of AVS (P: .011), hypertension (P: .01) interventricular septal thickness (IVST) (P: .026), and posterior wall thickness (PWT) (P: .022). Multivariate logistic regression analyses demonstrated presence of PSW (95% confidence interval (1.058-6.505, P: .037) as an independent determinant of PWD. CONCLUSION: Assessment of presystolic A-wave on echocardiography examination may provide important information regarding the atrial conduction velocities that is a electrophysiological cause of AF. While there was a significant association between AVSc and PWD in univariate analysis, this significance disappeared in multivariate analysis.

Association Between C-Reactive Protein to Albumin Ratio and Left Ventricular Thrombus Formation Following Acute Anterior Myocardial Infarction.

Left ventricular thrombus (LVT) is associated with inflammatory response in survivors with anterior ST-elevation myocardial infarction (STEMI). The C-reactive protein to albumin ratio (CAR) has been proposed as a marker of inflammation. However, there is a lack of data with respect to the role of CAR in LVT development. We investigated the relationship between CAR and LVT development in patients with anterior STEMI treated percutaneously; 955 consecutive patients were enrolled and LVT was observed in 126 (13.2%) patients. Clinical, demographic, and laboratory parameters were recorded. The CAR was significantly higher in patients with LVT (12.6 [8.6-16.1] vs 18.1 [11.5-23], P < .001). Other independent predictors for LVT development were lower ejection fraction, the presence of left ventricular apical aneurysm, proximal left anterior descending lesion location, glycoprotein IIb/IIIa inhibitors treatment, >1 diseased arteries, higher total protein level, neutrophil count, and peak creatine kinase myocardial band activity. In conclusion, the CAR may be useful as a simple tool for predicting LVT development among survivors of anterior STEMI.

Anterior Tragal Crease Is Associated With SYNTAX Score in Non-ST-Segment Elevation Myocardial Infarction.

The main aim of this study was to investigate the relation between anterior tragal crease (ATC) and coronary artery lesion complexity and severity assessed using the SYNTAX score (SXscore) in patients with non-ST-segment elevation myocardial infarction (NSTEMI). A total of 121 patients with a first-time diagnosis of NSTEMI were consecutively enrolled. ATC was defined as ≥1 crease that was close to the tragus and descended anteriorly. SXscore was calculated using the SXscore algorithm. The SXscore was higher in the ATC-positive group than in the ATC-negative group (11.85 ± 8.20 vs 7.52 ± 6.38, P = .003). In the univariate analysis, hemoglobin (male: 11.7-17.4 g/dL, female: 11.7-16.1 g/dL; P = .006), diabetes mellitus (P = .031), current smoking (P = .022), and presence of ATC (P = .022) were significantly associated with increased SXscore. Multivariate analysis revealed ATC (95% confidence interval [CI]: 1.313-7.800, P = .011), current smoking (95% CI: 2.034-13.893, P = .001), and hemoglobin (95% CI: 0.433-0.822, P = .002) as independent determinants of increased SXscore. Anterior tragal crease is easily detected by physical examination. Presence of ATC in patients with NSTEMI may be a warning signal of complexity and severity of coronary artery disease (CAD).

Be aware of misdiagnosis tied to COVID-19 focusing: a case report of abciximab-induced alveolar haemorrhage thought to be SARS-CoV-2 in a patient with ST-segment elevation myocardial infarction.

BACKGROUND: Early diagnosis of diffuse alveolar haemorrhage (DAH) can be extremely difficult, as the common clinical picture is often attributed to more common clinical conditions. High degree of suspicion is key to diagnosis which can be much more difficult during the coronavirus disease 2019 (COVID-19) pandemic. CASE SUMMARY: A 61-year-old man with inferolateral ST-segment elevation myocardial infarction treated by a stent to the left circumflex artery and intravenous abciximab treatment was started for the high thrombus burden. Two hours later, the patient developed dyspnoea and hypoxaemia. Chest examination revealed diffuse rales over both lung fields. Chest X-ray revealed bilateral diffuse alveolar infiltrates, while the echocardiography was normal. Chest computed tomography (CT) was performed and the 'crazy paving appearance', which is the typical radiological finding of COVID-19, was reported. The patient was considered to be suspected of COVID-19 and was transferred to a quarantine unit. Real-time reverse transcriptase-polymerase chain reaction (RT-PCR) test was obtained and azithromycin and hydroxychloroquine were initiated. 48 h later, 2.6 mmol/L reduction was observed in haemoglobin levels and haemoptysis was developed. After the second negative RT-PCR with an interval of 24 h, CT was repeated and the patient was diagnosed to have abciximab-induced DAH. The patient was later followed up conventionally and discharged after two weeks without additional complications. DISCUSSION: DAH and COVID-19 might share common clinical and radiological findings during examination. The physicians must be aware of the high motivation of the COVID-19 pandemic which can lead to misdiagnosis by overlooking other important clinical conditions.

Presystolic Wave is Associated with Subclinical Left Ventricular Dysfunction Assessed by Myocardial Performance Index in Type 2 Diabetes Mellitus.

BACKGROUND: Myocardial performance index (MPI), demonstrates both systolic and diastolic functions of the left ventricle. Presystolic wave (PSW) is frequently detected on Doppler examination of the left ventricular outflow tract and possible mechanism of PSW is impaired LV compliance and left ventricular stiffness. OBJECTIVE: To investigate the relationship between PSW and MPI in type 2 diabetic patients. METHOD: A total of 129 type 2 diabetic patients were included in this study. Patients were divided into two groups according to the presence of PSW on Doppler echocardiography. There were 90 patients (38 male, mean age 57.77 ± 10.91 years) in the PSW-positive group and 39 patients (13 male; mean age: 55.31 ± 11.29 years) in the PSW-negative group. The p values of < 0.05 were considered statistically significant. RESULTS: MPI was higher in PSW- positive group (0.63 ± 0.17vs 0.52 ± 0.13, p < 0.001). In addition, subclinical left ventricle dysfunction (LVD) was higher in the PSW- positive group (p = 0.029). Univariate analysis showed that the presence of PSW associated with abnormal MPI (p = 0.031). Pearson correlation analysis showed that PSW velocity correlated with MPI (r: 0.286, p = 0.006). CONCLUSION: Presence of the PSW on Doppler examination was associated with subclinical LV dysfunction in patients with DM type 2. This easy-to-perform echocardiographic parameter may be related to subclinical LVD among patients with type 2 DM.

The value of syntax score to predict new-onset atrial fibrillation in patients with acute coronary syndrome.

BACKGROUND AND AIM: New-onset atrial fibrillation (NOAF) has been associated with poor outcome in patients with acute coronary syndromes (ACS). Also, Syntax score (SS) is a scoring system that is derived from angiographic images and is associated with long-term mortality and major adverse cardiac events. In this study, we aimed to assess the relationship between SS and NOAF with known predictors of atrial fibrillation. METHODS: In a prospective, single-center, cross-sectional study, 692 patients who were diagnosed with coronary artery disease for the first time were enrolled consecutively. NOAF was defined as atrial fibrillation, which was documented after hospital admission. SS was calculated by a computer software. Multivariable logistic regression analyzes were used to detect the relationship between variables and NOAF. RESULTS: New-onset atrial fibrillation was detected in 82 patients (11.8%). Patients with NOAF had higher SS (22, interquartile range 18.3-25.1, vs. 12, interquartile range 7-19.5, p < 0.001). According to multivariable logistic regression analysis for NOAF, SS were independently and significantly associated (OR, 1.103; 95% confidence interval, 1.047-1.163; p < 0.001). Other independent predictors of NOAF were TIMI flow <3, C reactive protein, left ventricular ejection fraction, left atrial volume index and E/E' ratio. The optimal cut-off value for SS was 18 for the development of NOAF with 82% sensitivity and 68% specificity (area under the curve: 0.795, 95% confidence interval 0.749-0.841, p < 0.001). CONCLUSION: Syntax score may be helpful to identify for patients who would develop atrial fibrillation in the setting of ACS.

Presystolic wave is associated with carotid intima media thickness.

INTRODUCTION: Carotid intima media thickness (CIMT), a direct marker of atherosclerosis, has emerged as a promising means for cardiovascular risk evaluation. Presystolic wave (PSW) is commonly detected by the Doppler interrogation of the left ventricular outflow tract (LVOT). It is thought to be a result of a stiff left ventricle and impaired LV compliance. Herein, we aimed to investigate a possible association between carotid intima media thickness, an atherosclerotic marker, and PSW. METHOD: We prospectively enrolled 282 patients divided into two groups based on the presence of PSW: 221 (89F; mean age: 49.3 ± 11.5 years) had PSW on Doppler examination while 61 patients (32F; mean age: 46.4 ± 10.3 years) did not. Both groups were compared with respect to demographic, clinical properties, and CIMT. RESULTS: Both groups had comparable age, body mass index, and diabetes mellitus, hypertension, dyslipidemia, smoking, and family history for coronary heart disease. PSW-positive group had significantly higher CIMT (PSW-positive: 0.59 ± 0.22 mm vs PSW-negative: 0.42 ± 0.11 mm; P < 0.001) than PSW-negative group. Multivariate analysis showed that the independent predictors of increased CIMT were age (95% CI; 1.044-1.101, P < 0.001), dyslipidemia (95% CI; 0.147-0.664, P = 0.002), and the presence of PSW (95% CI; 2.168-7.836, P < 0.001).Correlation analysis showed that PSW velocity is correlated with increased CIMT in PSW-positive group (r: 0.418, P < 0.001). CONCLUSION: Assessment of PSW on TTE is easy and feasible method. Presence of PSW and increased PSW velocity on TTE might provide information that we should be careful in terms of subclinical atherosclerosis.
