Background: The association between the presence of diagonal earlobe crease (ELC) and coronary artery disease (CAD) still remains controversial. Objective: The aim of this study was to evaluate the association between bilateral ELC and CAD. Methods: 415 patients were examined for the presence or absence of bilateral ELC, angiographic evidence of CAD and coronary risk factors. The patients were divided into 2 groups according to angiographic evidence of CAD. Results: Bilateral ELC was significantly and positively correlated with CAD, hypertension, age, male gender, cigarette smoking and family history of CAD. The ELC was an independent variable for CAD. The observed sensitivity, specificity, positive predictive value and negative predictive value of the bilateral ELC for the diagnosis of CAD were in the following order: 51.3, 84.8, 89.4 and 41.2%. Conclusion: The presence of bilateral ELC was significantly associated with CAD and coronary risk factors. The bilateral ELC was an important dermatological indicator of CAD, and it might be a useful diagnostic tool in the clinical examination of patients.

Background/Aims: The Mehran risk score (MS) was adopted to predict the development of contrast-induced nephropathy (CIN) and includes clinical and procedural variables. In this study, we aimed to evaluate the value of MS in the prediction of CIN development after transcatheter aortic valve implantation (TAVI). Methods: Ninety-three patients (47 females; mean age, 77.2 ± 7.6 years) who underwent aortic valve replacement with TAVI for severe aortic stenosis in our center between June 2013 and November 2014 were included in the study. Patients were categorized into four risk groups based on MS: low (≤5), moderate (6-10), high (11-15), and very high (≥16). Results: CIN was recorded in 24 patients after TAVI (25.8%). The amount of contrast medium was significantly higher in the CIN+ group (p = 0.029), and total mortality was higher in the CIN+ group than in the CIN- group (20.1 vs. 2.9%, respectively; p = 0.024). In univariate analysis, diabetes mellitus, coronary artery disease, ejection fraction, baseline creatinine, baseline glomerular filtration rate, contrast medium volume, and MS were found to be significant risk factors for CIN (p < 0.05 for all). The receiver operating characteristic analysis of the significant variables in multivariate regression analysis revealed that the cutoff MS to predict the development of CIN was 13.0 (area under the curve, 0.654; 95% confidence interval, 0.495-0.758; sensitivity, 62%; specificity, 68%). Conclusion: MS is a predictor of CIN development after TAVI. We think that the use of MS in clinical practice may decrease renal complications after TAVI.

Background/Aim: Transcatheter aortic valve implantation (TAVI) is a method which is increasingly applied in severe aortic stenosis treatment. The development of contrast-induced nephropathy (CIN) after TAVI increases morbidity and mortality rates. Within the scope of this study, the importance of the contrast medium volume to glomerular filtration rate (CV/GFR) ratio in determining the development of CIN and the amount of CV that could be applied was evaluated. Methods: Seventy-two patients (aged 78.6 ± 11.6 years; 38 females) who underwent aortic valve replacement with the TAVI method between June 2013 and August 2014 were included in the study. CIN was defined as an absolute increase in serum creatinine of >0.5 mg/dl or a relative increase of >25% within 48-72 h after TAVI. CIN+ and CIN- patients were classified into two groups. The χ² test, t test, Mann-Whitney U test, ROC analysis, and univariate and multivariate regression analyses were applied for statistical analyses. Results: CIN was detected in 16 patients (22%) in our study. Baseline creatinine, baseline GFR, the Mehran risk score, CV, and the CV/GFR ratio were determined as the predictive factors of CIN development. A CV/GFR ratio of 3.9 was specified to predict CIN development with 71% sensitivity and 80% specificity. Conclusion: After TAVI, CIN may develop due to various reasons. In patients to whom TAVI was applied, the CV/GFR ratio may be a guideline helping to prevent the development of renal pathologies. The amount of contrast medium that can be given to a patient can be calculated in terms of baseline GFR.

The aim of this study was to evaluate and compare systolic blood pressure recovery and heart rate recovery (HRR) values obtained at various time intervals after maximal graded exercise treadmill testing between patients with metabolic syndrome (MS) and the controls without MS. To our knowledge, this is the first study indicating systolic blood pressure recovery (SBPR) impairment and its relations to HRR and other variables in this group of patients.The study population included 110 patients with MS (67 men, 43 women; mean age: 46 ± 9 years) and 110 control subjects who did not meet the criteria for MS (58 men, 52 women; mean age: 44 ± 10 years). All patients were selected from nonobese, apparently healthy sedentary individuals who had the ability to perform maximum exercise testing. SBPR was assessed by calculating the ratio of systolic blood pressure (SBP) obtained in the third minute of the recovery period to either the peak-exercise SBP or the SBP in the first minute of the recovery period after graded exercise testing. HRR values were calculated by subtracting the HR at the first, second, third, fourth, and fifth minutes of the recovery period from the HR reached at peak exercise.There was no significant difference found between the 2 groups with respect to age and sex distribution. As expected, patients with MS had higher waist circumference, fasting plasma glucose and serum triglyceride, and lower high-density lipoprotein cholesterol compared with control subjects. All HRR values calculated in the first, second, third, fourth, and fifth minutes were significantly detected lower in the MS group compared with the control group (HRR 1st: 32 ± 10 vs 36 ± 11; P = 0.009; HRR 2nd: 47 ± 10 vs 51 ± 11; P = 0.02; HRR 3rd: 53 ± 11 vs 58 ± 12; P = 0.001; HRR 4th: 57 ± 11 vs 64 ± 12; P < 0.001; HRR 5th: 60 ± 16 vs 69 ± 15; P < 0.001). In addition, calculated mean values for SBPR1 and SBPR2 were >1 in patients with MS (1.01 ± 0.2 vs 0.91 ± 0.1 and 1.01 ± 0.1 vs 0.94 ± 0.1) and these were statistically significant compared with the control group (P < 0.001 and P = 0.002, respectively). The existence of MS was found to be the only parameter that was independently and positively related to SBPR values in the study population.Our findings suggest that only the existence of MS itself, not the presence of any MS components, is independently associated with SBPRs. We are of the opinion that significantly impaired SBPR values, in addition to the decreased HRR values observed in this group of patients, such as those with MS, may especially help identify patients with potentially increased cardiovascular risk despite normal exercise stress testing findings.

BackgroundGRACE risk score (GS) is a scoring system which has a prognostic significance in patients with non-ST segment elevation myocardial infarction (non-STEMI).ObjectiveThe present study aimed to determine whether end-systolic or end-diastolic epicardial fat thickness (EFT) is more closely associated with high-risk non-STEMI patients according to the GS.MethodsWe evaluated 207 patients who had non-STEMI beginning from October 2012 to February 2013, and 162 of them were included in the study (115 males, mean age: 66.6 ± 12.8 years). End-systolic and end-diastolic EFTs were measured with echocardiographic methods. Patients with high in-hospital GS were categorized as the H-GS group (in hospital GS > 140), while other patients were categorized as the low-to-moderate risk group (LM-GS).ResultsSystolic and diastolic blood pressures of H-GS patients were lower than those of LM-GS patients, and the average heart rate was higher in this group. End-systolic EFT and end-diastolic EFT were significantly higher in the H-GS group. The echocardiographic assessment of right and left ventricles showed significantly decreased ejection fraction in both ventricles in the H-GS group. The highest correlation was found between GS and end-diastolic EFT (r = 0.438).ConclusionEnd-systolic and end-diastolic EFTs were found to be increased in the H-GS group. However, end-diastolic EFT and GS had better correlation than end-systolic EFT and GS.

The clinical effect of intracoronary thrombus aspiration during percutaneous coronary intervention in patients with unstable angina pectoris is unknown. In this study, we aimed to assess how thrombus aspiration during percutaneous coronary intervention affects in-hospital and 30-month mortality and complications in patients with unstable angina pectoris.We undertook an observational cohort study of 645 consecutive unstable angina pectoris patients who had performed percutaneous coronary intervention from February 2011 to March 2013. Before intervention, 159 patients who had culprit lesion with thrombus were randomly assigned to group 1 (thrombus aspiration group) and group 2 (stand-alone percutaneous coronary intervention group). All patients were followed-up 30 months until August 2015.Thrombus aspiration was performed in 64 patients (46%) whose cardiac markers (ie, creatinine kinase [CK-MB] mass and troponin T) were significantly lower after percutaneous coronary intervention than in those of group 2 (CK-MB mass: 3.80 ± 1.11 vs 4.23 ± 0.89, P = 0.012; troponin T: 0.012 ± 0.014 vs 0.018 ± 0.008, P = 0.002). Left ventricular ejection fraction at 6, 12, and 24 months postintervention was significantly higher in the group 1. During a mean follow-up period of 28.87 ± 6.28 months, mortality rates were 6.3% in the group 1 versus 12.9% in the group 2. Thrombus aspiration was also associated with significantly less long-term mortality in unstable angina pectoris patients (adjusted HR: 4.61, 95% CI: 1.16–18.21, P = 0.029).Thrombus aspiration in the context of unstable angina pectoris is associated with a limited elevation in cardiac enzymes during intervention that minimises microembolization and significantly improves both of epicardial flow and myocardial perfusion, as shown by angiographic TIMI flow grade and frame count. Thrombus aspiration during percutaneous coronary intervention in unstable angina pectoris patients has better survival over a 30-month follow-up period.

Neurofibromatosis is an autosomal dominant multi-system genetic disorder. Extra-cardiac vascular manifestations of neurofibromatosis have been previously described in many reports. However, coronary arterial involvements have been rarely described. A 17-year-old girl with neurofibromatosis presented to our institute with subacute myocardial infarction. Coronary angiogram revealed an aneurysm with thrombus in the left anterior descending artery.

Coronary artery perforation (CAP) is a rare but feared complication of percutaneous coronary intervention. With the advent of new devices and technologies, interventionalists attempt more complex lesions, including more calcified or tortuous vessels and chronic total occlusions, which increases the incidence of CAP. A short literature review, in addition to four cases of CAP, is presented in this report.
