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.

Is HFJV a better alternative ventilation technique for percutaneous dilatational tracheostomy? A randomized trial.

BACKGROUND: High-frequency jet ventilation (HFJV) has been used for the treatment of tracheal lesions, airway surgery, and treatment of secondary lesions after tracheostomy for many years however, reports on the use of HFJV during percutaneous dilatational tracheostomy (PDT) are limited. This study compares the use of traditional method, ventilation with laryngeal mask airway (LMA), and HFJV through endotracheal tube (ETT) with respect to the duration of PDT procedure and complications. METHODS: Seventy-five patients were randomized into one of the three groups with computer-generated random numbers: Group ETT (N.=25), group LMA (N.=25), and group HFJV (n=25). Demographic data, duration of PDT, complications such as ETT cuff puncture and tube transaction, accidental extubation, difficult cannula insertion, bleeding, desaturation during the procedure, arterial blood gases immediately before and after the procedure have been recorded. RESULTS: Mean time for successful PDT in group ETT was 5.9±1.35 minutes, in group LMA 4.96±0.78 minutes, and 3.88±0.78 minutes in group HFJV. PDT duration was shorter in the LMA group than in the ETT group (P<0.05). In the HFJV group, the PDT duration was shorter than the LMA group (P<0.05) and the ETT group (P<0.001). In terms of the total number of complications, significantly fewer complications were observed in the HFJV group compared with group ETT and group LMA. CONCLUSIONS: HFJV may be a more effective alternative method for airway management during PDT, facilitating and reducing the duration of the intervention.

Comparison of cervical spine motion during intubation with a C­MAC D­Blade® and an LMA Fastrach®.

BACKGROUND: This prospective randomized study compared cervical motion during intubation with a C­MAC D­Blade® and with a laryngeal mask airway LMA Fastrach®. MATERIAL AND METHODS: The participants in this study were 52 ASA I-III patients aged 18-70 years and assigned for elective cervical discectomy. The patients were randomly selected for intubation with a C­MAC D­Blade® (group V) or an LMA Fastrach® laryngeal airway (group F). Both groups received the same induction of anaesthesia. The first lateral view was X­rayed while the head and neck were in a neutral supine position and the second exposure was taken during the passage of the endotracheal tube through the vocal cords for group V and during the advance of the endotracheal tube for group F. The occiput-C1 (C0-C1), C1-C2 and C2-5 angles were measured. The angle formed by the line between the occipital protuberance and anterior process of the foramen magnum and the line between the central point of C1 spinous process and the anterior process of the foramen magnum was defined as angle A. The differences between the angles were calculated. Overall intubation success and first-pass success (success at the first attempt) were recorded. RESULTS: The change in angulations between C0-C1 during intubation was significantly lower in group F than in group V (2.780 ± 2.10 vs. 6.040 ± 4.10, p = 0.007). Before intubation, angle A was 14.40 ± 3.90 in group V and 13.80 ± 3.70 in group F (p = 0.627). During intubation, angle A was significantly smaller for group V than for group F (9.10 ± 2.40 vs. 10.70 ± 2.90, p = 0.04). The number of successful intubations were significantly higher in group V (100% of intubations were successful on the first attempt for group V, vs. 80% for group F, p = 0.023). CONCLUSION: Intubation with both a C­MAC D­Blade and a Fastrach LMA resulted in cervical motion but within safe ranges. Intubation with a C-mac D blade might be preferred because the Fastrach LMA may result in more failed intubation attempts in patients with cervical spine disorders.

Multislice/multidetector-row computed tomography findings of a rare coronary anomaly: the first septal perforator branch originating from the left main coronary artery.

Multislice/multidetector-row computed tomography (MDCT) is now widely used for noninvasive assessment of coronary arteries, and it may sometimes reveal coronary anomalies. Detection of such anomalies may be relevant both during follow-up and for planning cardiac or coronary surgical/interventional procedures. These anomalies may be missed unless carefully sought. In this paper, we present the MDCT images of a first septal perforator branch originating from the left main coronary artery, which represents an extremely rare coronary anomaly. To the best of our knowledge, this is the first case in the literature where MDCT images are presented.

Oral mask ventilation is more effective than face mask ventilation after nasal surgery.

OBJECTIVE: To evaluate and compare the face mask (FM) and oral mask (OM) ventilation techniques during anesthesia emergence regarding tidal volume, leak volume, and difficult mask ventilation (DMV) incidence. DESIGN: Prospective, randomized, crossover study. SETTING: Operating room, training and research hospital. SUBJECTS: American Society of Anesthesiologists physical status I and II adult patients scheduled for nasal surgery. INTERVENTIONS: Patients in group FM-OM received FM ventilation first, followed by OM ventilation, and patients in group OM-FM received OM ventilation first, followed by FM ventilation, with spontaneous ventilation after deep extubation. The FM ventilation was applied with the 1-handed EC-clamp technique. The OM was placed only over the mouth, and the 1-handed EC-clamp technique was used again. A child's size FM was used for the OM ventilation technique, the mask was rotated, and the inferior part of the mask was placed toward the nose. MEASUREMENTS: The leak volume (MVleak), mean airway pressure (Pmean), and expired tidal volume (TVe) were assessed with each mask technique for 3 consecutive breaths. A mask ventilation grade ≥3 was considered DMV. MAIN RESULTS: DMV occurred more frequently during FM ventilation (75% with FM vs 8% with OM). In the FM-first sequence, the mean TVe was 249±61mL with the FM and 455±35mL with the OM (P=.0001), whereas in the OM-first sequence, it was 276±81mL with the FM and 409±37mL with the OM (P=.0001). Regardless of the order used, the OM technique significantly decreased the MVleak and increased the TVe when compared to the FM technique. CONCLUSION: During anesthesia emergence after nasal surgery the OM may offer an effective ventilation method as it decreases the incidence of DMV and the gas leak around the mask and provides higher tidal volume delivery compared with FM ventilation.

Spinal anaesthesia with hyperbaric prilocaine in day-case perianal surgery: randomised controlled trial.

BACKGROUND: The local anaesthetics used in day-case spinal anaesthesia should provide short recovery times. We aimed to compare hyperbaric prilocaine and bupivacaine in terms of sensory block resolution and time to home readiness in day-case spinal anaesthesia. MeTHODS: Fifty patients undergoing perianal surgery were randomized into two groups. The bupivacaine-fentanyl group (Group B) received 7.5 mg, 0.5% hyperbaric bupivacaine + 20 µg fentanyl in total 1.9 mL. The prilocaine-fentanyl group (Group P) received 30 mg, 0.5% hyperbaric prilocaine + 20 µg fentanyl in the same volume. RESULTS: Time to L1 block and maximum block was shorter in Group P than in Group B (Group P 4.6 ± 1.3 min versus Group B 5.9 ± 01.9 min, P = 0.017, and Group P 13.2 ± 7.5 min versus Group B 15.3 ± 6.6 min, P = 0.04). The time to L1 regression and S3 regression of the sensorial block was significantly shorter in Group P than in Group B (45.7 ± 21.9 min versus 59.7 ± 20.9 min, P = 0.024, and 133.8 ± 41.4 min versus 200.4 ± 64.8 min, P < 0.001). The mean time to home readiness was shorter for Group P than for Group B (155 ± 100.2 min versus 207.2 ± 62.7 min (P < 0.001)). CONCLUSION: Day-case spinal anaesthesia with hyperbaric prilocaine + fentanyl is superior to hyperbaric bupivacaine in terms of earlier sensory block resolution and home readiness and the surgical conditions are comparable for perianal surgery.

Pseudoexfoliation syndrome and coronary artery ectasia.

AIMS: To determine whether pseudoexfoliation syndrome is associated with coronary artery ectasia or not. METHODS: This cross-sectional study was undertaken at Bulent Ecevit University's Ophthalmology Department with the participation of the Cardiology Department. Eighty consecutive patients who underwent coronary angiography and were classified into two groups-those diagnosed with a normal coronary artery (n=40) and those diagnosed with coronary artery ectasia (n=40)-were included in the study. Pseudoexfoliation was diagnosed if typical exfoliation material was found to be present on the anterior surface of the lens, the iris, or at the pupillary border on slit-lamp examination. Age, sex, presence of pseudoexfoliation material, hypertension, diabetes mellitus, hyperlipidemia rates, cigarette smoking history, and family history of coronary artery disease were compared between the two groups. The continuous variables were compared by using the independent sample t-test or the Mann-Whitney U-test, and the categorical variables were compared using Pearson's χ(2)-test or Fisher's Exact χ(2)-test for the two groups. RESULTS: There was no difference in demographic data of both groups. The presence of pseudoexfoliation material was more common in patients with coronary ectasia compared with controls [(n=21 (52.5%) vs n=8 (20%), P=0.005)]. In all patients, there was a higher glaucoma rate in the patients with pseudoexfoliation syndrome [n=7 (24.1%), 6 CAE (+), 1 CAE (-)] than in the normal patients [n=2 (3.9%), 2 CAE (-)] (P=0.010). CONCLUSIONS: In this study, we found a possible association of pseudoexfoliation and coronary artery ectasia. Coronary artery ectasia patients had higher prevalence of pseudoexfoliation.

Plateletcrit. A platelet marker associated with saphenous vein graft disease.

BACKGROUND: Saphenous vein graft disease (SVGD) after by-pass surgery is an important cause of morbidity and mortality for patients with coronary artery disease. Comprehensive evaluation of biochemical and hematological parameters associated with this problem is limited. Plateletcrit (PCT) provides complete information on total platelet mass, but it has not been previously studied. In this study, we examined the relationship between SVGD and platelet parameters such as PCT, mean platelet volume, platelet count, and platelet distribution. METHODS: We retrospectively analyzed 14,398 patients who underwent coronary angiography between February 2006 and August 2012. Records from 893 patients with previous coronary artery by-pass graft operation were re-evaluated. A total of 251 cases were divided into two groups (127 patients receiving a saphenous vein graft; 124 patients diagnosed with SVGD) and hematological and biochemical parameters were compared. RESULTS: There were no significant differences in clinical characteristics between the two groups except that the SVGD group had a higher median time from surgery to coronary angiography than the patent saphenous vein graft group [7 years (2-16) vs. 5 years (2-15), p < 0.001]. The SVGD groups also had significantly higher median PCT, mean platelet volume, platelet count, uric acid level, and red blood cell distribution width. The cut-off value for PCT was found to be 0.188 for predicting SVGD, with an 80.65 % sensitivity and 81.1 % specificity. CONCLUSION: Plateletcrit has an important predictive value for SVGD, and it could be used as a marker for anti-platelet therapy to prevent graft atherosclerosis in patients undergoing by-pass surgery.

Framingham risk score and severity of coronary artery disease.

OBJECTIVES: Coronary artery disease (CAD) is a leading cause of morbidity and mortality worldwide. Easy-to-perform and reliable parameters are needed to predict the presence and severity of CAD and to implement efficient diagnostic and therapeutic modalities. We aimed to examine whether the Framingham risk scoring system can be used for this purpose. METHODS: A total of 222 patients (96 women, 126 men; mean age, 59.1 ± 11.9 years) who underwent coronary angiography were enrolled in the study. Presence of > %50 stenosis in a coronary artery was assessed as critical CAD. The Framingham risk score (FRS) was calculated for each patient. CAD severity was assessed by the Gensini score. The relationship between the FRS and the Gensini score was analyzed by correlation and regression analyses. RESULTS: The mean Gensini score was 18.9 ± 25.8, the median Gensini score was 7.5 (0-172), the mean FRS was 7.7 ± 4.2, and the median FRS was 7 (0-21). Correlation analysis revealed a significant relationship between FRS and Gensini score (r = 0.432, p < 0.0001). This relationship was confirmed by linear regression analysis (ß = 0.341, p < 0.0001). A cut-off level of 7.5 for FRS predicted severe CAD with a sensitivity of 68 % and a specificity of 73.6 % (ROC area under curve: 0.776, 95 % CI: 0.706-0.845, PPV: 78.1 %, NPV: 62.3 %, p < 0.0001). CONCLUSION: Our work suggests that the FRS system is a simple and feasible method that can be used for prediction of CAD severity. As the sample size was small in our study, further large-scale studies are needed on this subject to draw solid conclusions.

The dose-dependent neuroprotective effect of alpha-lipoic acid in experimental spinal cord injury.

BACKGROUND AND PURPOSE: Free radical production after spinal cord injury (SCI) plays an important role in secondary damage. The aim of this study was to investigate neuroprotective effects of the powerful antioxidant alpha-lipoic acid (ALA) in a spinal cord clip compression injury model. MATERIAL AND METHODS: Fifty-six Sprague-Dawley rats, weighing between 210 and 300 g, were randomly divided into seven groups. Spinal cord injury was performed by an aneurysm clip placed extradurally at the level of T9. Group 1 (sham) received laminectomy only. Group 2 (control) received SCI; Group 3 received 30 mg/kg of methylprednisolone sodium succinate (MPSS); Groups 4, 5, 6 and 7 received ALA at doses of 50, 100, 150, 200 mg/kg, respectively, via the intraperitoneal route immediately after SCI. The rats were neurologically tested 24 hours after trauma. Spinal cord samples from injury sites were harvested for measurement of lipid peroxidation products and histopathological evaluation. RESULTS: Spinal cord malonyldialdehyde levels of rats in treatment groups decreased after administration of ALA. The difference between the trauma group and groups receiving MPSS-ALA was statistically significant. The difference between the ALA (50, 100, 150 mg/kg) and MPSS groups was insignificant. Group 7 (ALA 200 mg/kg) was excluded from the study because of the possible toxic effect. Alpha lipoic acid and MPSS had similar effects on spinal cord injury in terms of lipid peroxidation, neurological recovery and histopathological changes. CONCLUSIONS: Alpha lipoic acid at a dose range of 50-150 mg/ kg is as effective as MPSS (30 mg/kg) in neuroprotection after SCI. Further, more detailed experimental studies are needed to determine the effects of ALA on the detrimental results of secondary SCI before its use in humans.

A multicenter study on experience of 13 tertiary hospitals in Turkey in patients with infective endocarditis.

OBJECTIVE: The aim of this retrospective multicenter study was to investigate the clinical manifestations, microbiological profile, echocardiographic findings and management strategies of infective endocarditis (IE) in Turkey. METHODS: The study population consisted of 248 Turkish patients with IE treated at 13 major hospitals in Turkey from 2005 to 2012 retrospectively. All hospitals are tertiary referral centers, which receive patients from surrounding hospitals. Data were collected from the medical files of all patients hospitalized with IE diagnosed according to modified Duke Criteria. RESULTS: One hundred thirty seven of the patients were males. Native valves were involved in 158 patients while in 75 participants there was prosthetic valve endocarditis. Vegetations were detected in 223 patients (89%) and 52 patients had multiple vegetations. Mitral valve was the most common site of vegetation (43%). The most common valvular pathology was mitral regurgitation. The most common predisposing factor was rheumatic valvular disease (28%). Positive culture rate was 65%. Staphylococci were the most frequent causative microorganisms isolated (29%) followed by enterococci (11%). In-hospital mortality rate was 33%. CONCLUSIONS: Compared to IE in developed countries younger age, higher prevalence of rheumatic heart disease, more frequent enterococci infection and higher rates of culture negativity were other important aspects of IE epidemiology in Turkey.

[Cardiac device related infective endocarditis; analysis of 15 cases]. / Kardiyak cihazlara bagli olarak gelisen enfektif endokardit; 15 olgunun analizi.

OBJECTIVES: We aimed to investigate the demographic and clinical characteristics, echocardiographic and microbiologic features, and outcomes of patients with permanent pacemaker (PM) and implantable cardioverter-defibrillator (ICD) endocarditis in this study. STUDY DESIGN: The study population consisted of 15 patients with permanent PM and ICD endocarditis. Data on demographics, medications, clinical procedures, microbiology, echocardiography, surgery, and outcome were collected. RESULTS: The mean age of the patients was 57 ± 16. Seven patients (47%) were female. Of the 15 permanent PM and ICD endocarditis patients, 5 died during hospital follow-up (33%). Four patients (27%) experienced a pulmonary embolism. Culture-negative endocarditis was seen in 5 cases (33%). Staphylococci were the most common causative organisms (60%). Three patients had undergone surgical treatment (20%). CONCLUSION: Cardiac device-related endocarditis remain a rare but potentially fatal complication of device implantation.

Aortic elastic properties : effects of carvedilol versus nebivolol.

OBJECTIVES: The aim of this study was to compare the effects of the new generation ß-blocker anti-hypertensive drugs carvedilol and nebivolol on aortic elastic properties which are important indicators of hypertension-related morbidity and mortality. METHODS: A total of 50 patients who had been diagnosed with stage 1 hypertension according to the Joint National Committee (JNC) VII criteria and who had not received any anti-hypertensive treatment were enrolled in this study. Patients were randomized to receive either 25 mg/day carvedilol (n=25) or 5 mg/day nebivolol (n=25) for 3 months at the beginning of the study. Three patients (1 in the carvedilol group, 2 in the nebivolol group) who did not attend 3 month follow-up measurements were excluded from the study. The study was completed with 47 patients (25 women; mean age: 49 ± 9 years). The aortic elastic parameters such as aortic strain (AS), aortic distensibility (AD), and aortic stiffness index (ASI) were measured by echocardiography. RESULTS: Carvedilol and nebivolol provided a similar decline in both systolic and diastolic blood pressures (-12/-7 mmHg, p<0.0001 and -12/-7 mmHg, p=0.002, respectively). Both carvedilol and nebivolol induced a significant decrease in heart rate (-15 bpm, p<0.0001, -17 bpm, p<0.0001, respectively). Even though the heart rate at the end of the treatment was lower for the nebivolol group, the rate of decrease of heart rates between carvedilol and nebivolol groups was not statistically significant (p=0.074). Both groups demonstrated improvements in the diastolic functions of the left ventricle where certain values showed more improvement for the nebivolol group. Both groups showed improvements in AS and AD rates compared to basal rates; however, these improvements were not statistically significant. Although the improvement rates in AS, AD, and ASI were higher in the nebivolol group compared to the carvedilol group, the differences were not statistically significant (p=0.091, p=0.095, p=0.259, respectively). CONCLUSION: Both carvedilol and nebivolol induced a decrease in blood pressure and heart rate and showed an improvement in left ventricular diastolic functions. It was observed that both drugs did not cause deterioration in the aortic elastic properties but a slight improvement was seen. However, this improvement was not statistically significant. The improvement was more explicit in the nebivolol group. It may be concluded that nebivolol is slightly superior to carvedilol in reducing heart rate and improving left ventricular diastolic functions. However, further long-term studies with larger sample sizes should be performed in order to better define the effects of both drugs.

Persistent left superior vena cava, absence of the innominate vein, and upper sinus venosus defect : a rare anomaly detected using bubbles.

Superior vena cava anomalies are rare malformations that are typically seen with other congenital cardiac defects. Although a persistent left superior vena cava is the most common anomaly of the systemic venous return in the thorax, its combination with an upper sinus venosus defect and absence of the innominate vein is extremely rare. Here, we report a patient diagnosed with these anomalies based on a bubble study and confirmed with magnetic resonance imaging.

Tirofiban in Takotsubo cardiomyopathy. Atypical broken heart syndrome with extremely fast recovery: a case report.

Takotsubo cardiomyopathy, also known as broken heart syndrome, is similar to acute coronary syndrome. The absence of significant stenosis on coronary angiography and spontaneous improvement of ventricular akinesia are very important features that distinguish this syndrome from acute coronary syndromes. Despite the fact that ST segment elevations are typically encountered, atypical presentation without ECG changes should be kept in mind. We herein report the case of a 61-year-old woman who presented with mid-apical left ventricular akinesia resolving within 24 h.

Assessment of left ventricular systolic and diastolic dyssynchrony with tissue Doppler echocardiography in patients with heart failure and narrow QRS complex.

AIM: Cardiac dyssynchrony is a well known entity in patients with wide QRS complex (>120 ms). Dyssynchrony may also cause ventricular dysfunction in heart failure patients with narrow QRS complexes. In the study, the presence and extent of cardiac dyssynchrony were investigated in patients with heart failure both with narrow and wide QRS complexes using tissue Doppler echocardiography (TDE). METHODS: Forty-nine patients with heart failure, were included to the study. The first group of 30 patients with a QRS duration of <120 ms (23M; mean age, 64±10.1 years) and the second group consisted of 19 patients with a QRS duration of >120 ms (12M; mean age, 65±11.6 years). In order to examine cardiac synchronization, TDE was performed. Systolic and diastolic intraventricular dyssynchrony and interventricular dyssynchrony were calculated. In order to define systolic and diastolic dyssynchrony, intraventricular delay was accepted as >60 ms, and interventricular delay was accepted as >40 ms. RESULTS: Left ventricular systolic dyssynchrony was detected in 18 patients (60%) within the narrow QRS group and in 18 patients (94%) within the wide QRS group. Interventricular dyssynchrony was detected in 17 patients (56%) within the narrow QRS group and in 18 patients (94%) within the wide QRS group. For systolic dyssynchrony, correlations existed between intraventricular delay and QRS duration (r=0.48), left ventricular end diastolic diameter (r=0.62), left ventricular end systolic diameter (r=0.61), and EF (r=-0.63). Similarly, correlations existed between interventricular delay and QRS duration (r=0.58), left ventricular end diastolic diameter (r=0.65), left ventricle end systolic diameter (r=0.64), and EF (r=-0.64). CONCLUSION: The present study suggested that systolic or diastolic dyssynchrony exists despite normal levels of QRS duration.

Effects of impaired fasting glucose on aortic elasticity.

The pathophysiology of atherosclerosis development in patients with diabetes mellitus (DM) is similar to that in nondiabetics. However, atherosclerosis develops earlier and runs a rapid course in patients with diabetes. Aortic stiffness, strain and distensibility are the parameters used to assess an increase in arterial stiffness and can be measured by invasive and non-invasive methods.Aortic elastic properties were compared among patients with normal oral glucose tolerance test but impaired fasting glucose and healthy individuals. The study group consisted of 50 subjects with impaired fasting glucose who had no known risk factors for atherosclerosis. The control group was composed of the same number of volunteers.It was found that aortic strain and distensibility were reduced (8.78±4.3 vs. 10.65±2.6 p<0.01 and 4.1±2.1 vs. 5.1±1.7 p<0.01 respectively) and aortic stiffness index was significantly increased (6.9±3.2 vs. 5.01±1.6, p<0.0001) in patients with impaired fasting glucose compared to those in the control group.It was demonstrated that aortic elasticity was impaired in those with impaired fasting glucose, which indicates that these patients should be kept under close follow-up for cardiovascular events.
