Carotid Intima Media Thickness and Its Association With Total Bilirubin Levels in Patients With Coronary Artery Ectasia.

Atherosclerosis plays an important role in the etiopathogenesis of coronary artery ectasia (CAE). The relationship between total bilirubin (TBil) and carotid intima media thickness (cIMT) in patients with CAE has not been fully investigated. Hence, we evaluated the relationship between TBil levels and cIMT in 142 consecutive eligible patients with CAE, newly diagnosed coronary artery disease (CAD), and normal coronary arteries. There were no significant differences in TBil (P = .772) and cIMT (P = .791) between the CAE and CAD groups. Bilirubin levels were significantly lower in both CAE and CAD groups compared to the controls (P < .01). The cIMT was significantly higher in both CAE and CAD groups compared to control participants (P < .01). A negative correlation between cIMT and TBil was found in all the groups (P < .01, r = .354). We show for the first time that patients with CAE and CAD have lower TBil and greater cIMT compared to controls with normal coronary angiograms.

An unusual complication during alcohol septal ablation: severe left anterior descending artery vasospasm causing cardiac arrest: a case report and review of the literature.

BACKGROUND: Septal reduction therapy can be considered along the lines of hypertrophic obstructive cardiomyopathy patients who have drug-refractory symptoms. This can be applied either surgical myectomy or either alcohol septal ablation (ASA). Alcohol septal ablation has been performed successfully since the first announcement of ASA in 1995. CASE SUMMARY: We present a case report of coronary artery vasospasm that occurred in the left anterior descending artery (LAD) during ASA. We performed ASA via first septal artery. Two cubic centimetre of 99% ethanol was slowly injected and 10 min later balloon was withdrawn. Then the patient felt severe chest pain; his systolic blood pressure went down quickly and fibrillated. We started the cardiopulmonary resuscitation (CPR). After CPR, the rhythm was achieved total 4 min later cardiac arrest but blood pressure was low. Emergent coronary angiography showed that coronary spasm caused severe occlusion in the LAD segment just after the first septal artery and impaired coronary flow nearly totally in the LAD just after septal artery. At that time, we decided to implant a stent due to the patient's serious condition and a 3.5 × 18 mm drug-eluting stent was implanted. We performed control angiography to patient 3 days later of the procedure and LAD flow was TIMI 3. DISCUSSION: The causes of LAD occlusion are alcohol leakage, dissection, and vasospasm. It is important to detect the correct reason for appropriate treatment. Alcohol leakage impairs and causes coronary flow disruption; this can cause ventricular wall motion abnormalities. In our case, there was severe spasm in the LAD coronary artery and LAD flow was severely impaired. On echocardiogram, there was no myocardial wall motion abnormality. So alcohol leakage was ruled out. Left anterior descending artery image was not typical dissection. As a result of these findings, we concluded that the cause of LAD occlusion was coronary artery vasospasm.

Relationship between the extent of coronary artery disease and in-stent restenosis in patients with acute ST-segment elevation myocardial infarction undergoing primary percutaneous coronary intervention.

OBJECTIVE: The pathophysiological mechanism of in-stent restenosis (ISR) is different from atherosclerosis of native coronary arteries. The aim of this study was to evaluate the relationship between ISR and the extent of coronary artery disease (CAD), and to identify other risk factors associated with ISR in ST-segment elevation myocardial infarction (STEMI) patients. METHODS: A total of 372 consecutive patients presenting with first acute STEMI who were successfully treated with primary percutaneous coronary intervention within 12 hours from the onset of symptoms and who had an angiographic follow-up at 3 months were included in the study. The extent of CAD was calculated using the Gensini score. RESULTS: The incidence of ISR observed in our group of patients was 23.4% (n=87). The mean Gensini score was significantly higher in patients with ISR when compared with group without restenosis (69 [range: 51-90] vs 42 [range: 32-61]; p<0.001). The presence of diabetes mellitus, left ventricular ejection fraction (LVEF), and low-density lipoprotein cholesterol (LDL-C) level differed significantly between the 2 groups (p<0.05 for all). Stent diameter and stent length were found to be significantly different between the ISR group and the no-restenosis group (p<0.05 for both). In multivariate logistic regression analysis, the Gensini score, stent diameter, stent length, LVEF, and LDLC were independently associated with ISR. CONCLUSION: Despite the differences in the underlying pathophysiological mechanism of ISR and native coronary atherosclerosis, patients with a greater extent of CAD should be considered candidates for future stent restenosis.

Relação entre o Escore de Gensini e Mortalidade Intra-Hospitalar em Pacientes com Infarto do Miocárdio com Supradesnivelamento do Segmento ST / The Relationship Between Gensini Score and In-Hospital Mortality in Patients with ST-Segment Elevation Myocardial Infarction

Fundamento: Até o momento, diversos escores de risco baseados em pacientes foram estabelecidos para a predição de mortalidade em pacientes com infarto do miocárdio com supradesnivelamento do segmento ST (IAMCSST). O escore de Gensini foi originalmente desenvolvido para quantificar a gravidade de doença arterial coronariana (DAC). Objetivos: Avaliar a associação entre a gravidade de DAC avaliada pelo escore de Gensini e mortalidade intra-hospitalar em pacientes com IAMCSST submetidos à intervenção coronária percutânea primária (ICP-P). Métodos: Foram incluídos 539 pacientes com IAMCSST, submetidos à ICP-P dentro das primeiras 12 horas do início dos sintomas. A gravidade da DAC foi expressa como a soma do escore de Gensini para cada lesão. Variáveis demográficas, anamnese e características clínicas dos pacientes, bem como eventos hospitalares significativos, foram obtidos de relatórios médicos. Resultados: Dos 539 pacientes, 416 (77,2%) eram do sexo masculino, e a idade média era 59,14 ± 12,68 anos. A taxa de mortalidade intra-hospitalar foi de 5,4% (29 pacientes, 16 homens). A taxa de mortalidade foi de 10,5% em pacientes do sexo feminino e 3,8% em pacientes do sexo masculino (P=0,004). Os escores de Gensini médios mostraram-se significativamente diferentes na comparação entre pacientes que sobreviveram (54,54 ± 26,34) e aqueles que foram a óbito (80,17 ± 26,51) (P = 0,001). O modelo de análise multivariada de regressão de Cox de risco proporcional revelou que o escore de Gensini (P = 0,037), o sexo feminino (P = 0,039), níveis séricos de ureia (P = 0,041), níveis de ácido úrico (P = 0,008) e FEVE (P = 0,001) estavam independentemente associados à mortalidade intra-hospitalar em pacientes com IAMCSST submetidos à ICP-P. Conclusões: O escore de Gensini está independentemente associado à mortalidade intra-hospitalar em pacientes com IAMCSST tratados com ICP-P. Portanto, o escore pode ter um papel importante na estratificação de risco de pacientes com IAMCSST

Background: To date, several validated patient-based risk scores have been established to predict mortality and morbidity in patients presenting with ST-segment elevation myocardial infarction (STEMI). The Gensini score was originally developed to quantify the severity of coronary artery disease (CAD). Objectives: We intend to assess the association between severity of CAD assessed by Gensini score and in-hospital mortality in patients with STEMI undergoing primary percutaneous coronary intervention (P-PCI). Methods: A total of 539 patients presenting with acute STEMI, who underwent P-PCI within the first 12 hours from the onset of symptoms, were included. The severity of CAD was expressed as the sum of the Gensini scores for each lesion. Patients' demographic variables, medical histories and clinical features, as well as in hospital major adverse events were obtained from the medical reports. Results: Of these 539 patients, 416 (77.2%) were male and mean age was 59.14 ± 12.68 years. In-hospital mortality rate was 5.4% (29 patients; 16 men). Mortality rate was 10.5% in female patients and 3.8% in males (P = 0.004). Mean Gensini scores were significantly different in the comparison between patients who survived (54.54 ± 26.34) and those who died (80.17 ± 26.51) (P = 0.001). The multivariable Cox proportional hazards regression analysis model revealed that the Gensini score (P = 0.037), female gender (P = 0.039), serum urea levels (P = 0.041), uric acid levels (P = 0.008) and LVEF (P = 0.001) were independently associated with in-hospital mortality in patients with STEMI undergoing P-PCI. Conclusion: The Gensini score is independently associated with in-hospital mortality in STEMI patients treated with P-PCI. Therefore, it might play an important role in risk stratification of STEMI patients

The Relation Between No-Reflow Phenomenon and Complete Blood Count Parameters.

The no-reflow (NR) phenomenon represents an acute reduction in coronary blood flow without coronary vessel obstruction, coronary vessel dissection, spasm, or thrombosis. No reflow is an important complication among patients with acute ST-segment elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention (pPCI). The complete blood count (CBC) is one of the most frequently ordered laboratory tests in clinical practice. Various studies have evaluated the performance of CBC parameters to predict disease severity and mortality risk. Automated cell counters are routinely available in many clinical laboratories and can be used to determine red blood cell distrubiton width (RDW), platetecrit, platelet count, and and some ratios like the neutrophil-lymphocyte ratio and RDW-platelet ratio. These hematological markers have been reported to be independent predictors of impaired angiographic reperfusion and long-term mortality among patients with STEMI undergoing pPCI. In this context, we reviewed the role of admission CBC parameters for the prediction of NR in patients with STEMI undergoing pPCI.

The Relationship Between Plasma Whole Blood Viscosity and Cardiovascular Events in Patients With Chronic Kidney Disease.

BACKGROUND: Plasma levels of estimated whole blood viscosity (eWBV) have been increased by endothelial inflammation. Because there were no consistent data for assessing the eWBV levels for prediction of cardiovascular event (CVE) in patients with chronic kidney disease (CKD). We aimed to investigate the relationship between plasma eWBV levels and CVEs in patients with CKD. MATERIALS AND METHODS: We conducted a prospective, cross-sectional, long-term follow-up study, assessing the relationship between plasma eWBV levels and CVE (either fatal or nonfatal) in patients with newly diagnosed CKD. We also evaluated estimated glomerular filtration rate (eGFR), pentraxin 3 (PTX3), high-sensitivity C-reactive protein (hsCRP), and flow-mediated dilatation (FMD). RESULTS: Study patients were divided into 2 groups: patients with CVE and patients without CVE. The eWBV levels were higher in patients with CVE. Additionally, PTX3 and hsCRP were higher, and FMD and eGFR were lower in patients with CVE compared to those without CVE. According to the Cox regression analysis, WBV, plasma asymmetric dimethylarginine levels, FMD, hsCRP, eGFR, systolic blood pressure, calcium, and history of diabetes were independent predictors of CVEs in patients with CKD. Kaplan Meier survival curves were generated to establish the impact of the WBV on the cumulative survival of the cohort. Patients with eWBV values higher than 5.2 centipoise (cP) had lower survival rates when compared to patients with eWBV values lower than 5.2 cP (log rank = 4.49 df = 1 P = .034). CONCLUSION: In conclusion, plasma eWBV levels may increase the presence of lower eGFR and affect CVE in patients with CKD independent of classical and unconventional risk factors.

The relation between monocyte to HDL ratio and no-reflow phenomenon in the patients with acute ST-segment elevation myocardial infarction.

BACKGROUND: No-reflow phenomenon is a prognostic value in ST-segment elevation myocardial infarction (STEMI). Monocyte to high density lipoprotein ratio (MHR) has recently emerged as a marker of inflammation and oxidative stress in the cardiovascular disease. PURPOSE: In this study, we aimed to investigate the relation between MHR and no-reflow phenomenon in patients with STEMI undergoing primary percutaneous coronary intervention (pPCI). MATERIAL AND METHODS: A total of 600 patients with STEMI (470 men; mean age, 62 ± 12 years) admitted within 12 hours from symptom onset were included into this study. Patients were classified into 2 groups based on postintervention Thrombolysis in Myocardial Infarction (TIMI) flow grade: no-reflow-TIMI flow grade 0, 1, or 2 (group 1); angiographic success-TIMI flow grade 3 (group 2). RESULTS: According to admission whole-blood cell count results, the patients in the no-reflow group had significantly higher monocyte count and MHR values when compared with those of the reflow patients. After multivariate backward logistic regression, MHR remained independent predictors of no reflow after pPCI. Adjusted odds ratios were calculated as 1.09 for MHR (P< .001; confidence interval [CI], 1.07-1.12). Receiver operating characteristic curve analysis suggested that the optimum MHR level cutoff point for patients with no-reflow was 22.5, with a sensitivity and specificity of 70.2% and 73.3%, respectively (area under curve, 0.768; 95% CI, 0.725-0.811). CONCLUSION: In conclusion, MHR levels are one of the independent predictors of no reflow in patients with STEMI after pPCI.

Late embolization of the atrial septal occluder device into the abdominal aorta.

Although early device embolization is a well-known complication of percutaneous atrial septal defect (ASD) closure, late device embolization is rarely encountered and information about management of it are very limited. Herein, we reported a case of late ASD device embolization into the abdominal aorta at the level of the superior mesenteric artery, 8 months after percutaneous closure.

Behçet's disease and risk of vascular events.

PURPOSE OF REVIEW: We discuss the relationship between several factors and the risk of vascular events in patients with Behçet's disease. RECENT FINDINGS: Behçet's disease, a systemic, chronic relapsing vasculitis, is mainly seen in the Mediterranean area and is typically characterized by recurrent oro-genital ulcers, ocular inflammation, and skin manifestations, including articular, vascular, gastroenteric, and neurological involvement. It is a chronic inflammatory disease with relapses and remissions. The prognosis varies. Behçet's disease can cause venous or arterial lesions. Vascular involvement contributes to the mortality and morbidity associated with Behçet's disease. SUMMARY: The cause of thrombosis or vascular events in Behçet's disease remains incompletely understood; several factors have been studied with conflicting results. Vasculitis is considered to underlie several clinical manifestations of Behçet's disease.
