A missing coronary guidewire mimicking aortic dissection-a case report.

Background: A retained coronary guidewire following coronary angiography is an extremely rare complication. We present a case of a retained coronary guidewire from a percutaneous coronary intervention done 2 years ago. Case summary: An 80-year-old asymptomatic man with a history of ischemic heart disease and moderate aortic stenosis presented to the echocardiography lab for routine follow-up. Transthoracic echocardiography showed Moderate aortic stenosis and a suspected linear echogenic structure in the ascending aorta. trans-esophageal echocardiography was performed to reveal a mobile and linear echogenic structure originating from the sinuses of Valsalva/Sinotubular junction and extending to the ascending aorta. An electrocardiogram gated cardiac computed tomography was performed and showed A linear well-defined structure originating from the ostium of the left main coronary artery and extending to the ascending aorta-a coronary guidewire from an earlier procedure. A second look at the last invasive coronary angiography record demonstrated the same finding. A multidisciplinary heart team discussion was obtained and concluded that the risk of surgical or endovascular intervention outweighed the potential benefit. The patient was discharged home for a close clinical and echocardiographic follow-up. Discussion: A retained coronary guidewire is a rare complication that operators should be aware of. Management should be case-specific depending on clinical presentation.

Cardiac Tamponade in Patients Treated with Direct Oral Anticoagulants.

BACKGROUND: Direct oral anticoagulants (DOACs) are the treatment of choice for patients with non-valvular atrial fibrillation; however, bleeding risk remains significant. We reported a single-center experience with 11 patients who presented with hemorrhagic cardiac tamponade while treated with DOACs. OBJECTIVES: To evaluate the characteristics and clinical outcomes of patients under DOACs with cardiac tamponade. METHODS: We retrospectively identified 11 patients treated with DOACs admitted with pericardial tamponade in our cardiology unit during 2018-2021. RESULTS: The mean age was 84 ± 4 years; 7 males. Atrial fibrillation was the indication for anticoagulation in all cases. DOACs included apixaban (8 patients), dabigatran (2 patients), and rivaroxaban (1 patient). Urgent pericardiocentesis via a subxiphoid approach under echocardiography guidance was successfully performed in 10 patients. One patient was treated with urgent surgical drainage with a pericardial window. Reversal of anticoagulation using prothrombin complex concentrate and idarucizumab was given before the procedure to 6 patients treated with apixaban and one patient treated with dabigatran. One patient, initially treated with urgent pericardiocentesis, underwent pericardial window surgery due to re-accumulation of blood in the pericardium. The pericardial fluid analysis demonstrated hemopericardium. Cytology tests were negative for malignant cells in all cases. Discharge diagnoses regarding the cause of hemopericardium included pericarditis (3 patients) and idiopathic (8 patients). Medical therapy included non-steroidal anti-inflammatory drugs (1 patient), colchicine (3 patients), and steroids (3 patients). No patient died during hospitalization. CONCLUSIONS: Hemorrhagic cardiac tamponade is a rare complication of DOACs. We found good short-term prognosis following pericardiocentesis.

Relation of Intake of Saturated Fat to Atherosclerotic Risk Factors, Health Behaviors, Coronary Atherosclerosis, and All-Cause Mortality Among Patients Who Underwent Coronary Artery Calcium Scanning.

Although very brief questionnaires are commonly used to assess physical activity, an analogous approach for assessing diet quality within clinical practice has not been developed. Thus, we undertook an exploratory study to evaluate the association between a single-item questionnaire regarding dietary quality and patient risk profiles, lifestyle habits, lipid values, coronary artery calcium (CAC) scores and mortality. We assessed 15,368 patients who underwent CAC scanning, followed for a median of 12.1 years for all-cause mortality. Diet quality was assessed according to a single-item question regarding self-reported adherence to a low saturated fat diet (0 = never, 10 = always), with patients categorized into 4 dietary groups based on their response, ranging from low to very high saturated fat intake. We observed a significant stepwise association between reported saturated fat intake and smoking, exercise activity, obesity, and serum cholesterol, low density lipoprotein, and triglyceride values. Following adjustment for age and risk factors, patients reporting very high saturated fat intake had an elevated hazard ratio for mortality versus low saturated fat intake: 1.22 (95% confidence interval 1.04 to 1.44). The hazard ratio was no longer significant after further adjustment for exercise activity. Upon division of patients according to baseline CAC, a stepwise relationship was noted between increasing saturated fat intake and mortality among patients with CAC scores ≥400 (p = 0.002). Thus, within our cohort, just a single-item exploratory questionnaire regarding very high saturated fat intake revealed stepwise associations with health behaviors and cardiac risk factors, suggesting the basis for further development of a practical dietary questionnaire for clinical purposes.

Non-coronary cardiac calcifications and outcomes in patients with heart failure.

BACKGROUND: Calcium deposits on heart valves are considered a local manifestation of atherosclerosis and are associated with poor cardiovascular outcomes. The clinical significance of cardiac calcifications among heart failure (HF) patients, as assessed by echocardiography, is unknown. This study evaluated associations of cardiac calcifications with mortality and hospital admissions in this specific population. METHODS: Medical records of all patients who initiated ambulatory surveillance at our HF clinic during 2011-2018 were reviewed. Calcifications in the aortic valve, aortic root, or the mitral valve were evaluated. Patients with moderate to severe regurgitation or stenosis of the aortic or mitral valves were excluded. The primary endpoint was the composite of long-term all-cause mortality and HF hospitalizations. Secondary endpoints were long-term all-cause mortality and more than one hospitalization due to HF. RESULTS: This retrospective study included 814 patients (mean age 70.9 ± 13 years, 63.2% male). Of the total cohort, 350 (43%) had no cardiac calcifications and 464 (57%) had at least 1 calcified site. Considering the patients with no calcification as the reference group yielded a higher adjusted odds ratios for the composite endpoint, all-cause death, and recurrent HF hospitalizations, among patients with any cardiac calcification (OR = 1.68, 95%CI = 1.1-2.5, p = 0.01, OR=1.61, 95%CI = 1.1-2.3, p < 0.01, and OR = 1.50, 95%CI = 1.1-2.2, p < 0.01, respectively). CONCLUSIONS: We found an independent association between cardiac calcifications and the risk of death and HF hospitalizations among ambulatory HF patients. Cardiac calcifications evaluated during routine echocardiography may contribute to the risk stratification of patients with HF.

Simultaneous Tc-99m PYP/Tl-201 dual-isotope SPECT myocardial imaging in patients with suspected cardiac amyloidosis.

INTRODUCTION: Assessment of myocardial uptake of Tc-99m-pyrophosphate (Tc-99m PYP) is pivotal in distinguishing transthyretin-associated cardiac amyloidosis (ATTR) from light chain amyloid (AL). It is often difficult to differentiate myocardial uptake from blood pool radioactivity with planar imaging or SPECT. We studied whether simultaneous dual-isotope Tc-99m PYP/Tl-201 SPECT improves assessment of Tc-99m PYP uptake compared to single-isotope SPECT. METHODS: Simultaneous Tc-99m PYP/Tl-201 dual-isotope SPECT was acquired in 112 patients studied for possible cardiac amyloidosis. Visual interpretation was performed by two observers on single-isotope followed by dual-isotope SPECT. Heart-to-contralateral lung ratio (H/CL) of myocardial counts quantified by single-isotope and dual-isotope SPECT was compared between ATTR, AL, and no amyloidosis groups. RESULTS: In 112 patients (39 ATTR and 26 AL patients, and 47 no amyloidosis), a lower proportion of no amyloidosis and AL patients were classified visually as equivocal with dual-isotope SPECT compared to single-isotope SPECT (2% vs 19%, P = 0.02 and 8% vs 35%, P = 0.04, respectively). H/CL measurements with single-isotope and dual-isotope were lower in AL and no amyloidosis patients vs ATTR patients (P < 0.05). Interobserver agreement of visual assessment was improved with dual-isotope SPECT (P = 0.03). AUCs for detection of ATTR by visual assessment and H/CL quantification were higher with dual-isotope (0.94 and 0.95, respectively) compared to single-isotope SPECT (0.84, P = 0.001 and 0.92, P = 0.02). CONCLUSION: Tc-99m PYP/Tl-201 SPECT improves visual differentiation of ATTR and AL amyloidosis compared to single-isotope SPECT. Visual assessment and H/CL quantitation with dual-isotope SPECT provide similar discrimination between patients with ATTR and AL amyloidosis.

Olfactory impairment in patients with the fibromyalgia syndrome and systemic sclerosis.

Patients with autoimmune diseases often present with olfactory impairment. The aim of the study was to assess the olfactory functions of female patients with fibromyalgia (FM) compared with patients with systemic sclerosis (SSc) and with healthy female controls. Olfactory functions were assessed in 24 patients with FM, 20 patients with SSc and 21 age-matched healthy controls. The sense of smell was evaluated using the Sniffin' Sticks test including the three stages of smell: threshold, discrimination, and identification (TDI) of the different odors. The severity of fibromyalgia was assessed using the fibromyalgia impact questionnaire (FIQ). The short form 36 (SF-36) questionnaire was also completed in order to seek a relationship between the patients perception of quality of life and the different aspects of the smell sense. Depression was evaluated in both FM and SSc patients utilizing the Beck depression inventory-II (BDI-II) questionnaire. Patients with FM had significantly lower TDI smell scores compared with both SSc patients and healthy controls (p < 0.005, One-Way ANOVA). Hyposmia (defined as TDI scores below 30) were observed in 14 of 24 (42 %) patients with FM compared to 3 of 20 (15 %) patients with SSc and 1 of the healthy controls (4.3 %) (p < 0.02). FM patients had significantly lower thresholds of smell compared to both healthy controls and patients with SSc (p < 0.001), whereas for patients with SSc only the ability to discriminate between odors was impaired (p < 0.006). We could not detect any statistical correlation between smell abilities and clinical manifestation of SSc or the FIQ and SF-36 scores among FM patients. However the correlation between depression, defined by the BDI-II score, and the sense of smell differed between patients with FM and patients with SSc. As only among SSc patients a lower sense of smell correlated with a higher BDI-II score (p = 0.02). Our findings suggest that there is a decrease in the sense of smell both in FM and SSc patients compared with healthy controls. However these impairments differ between patients group and might represent different mechanisms that affect the sense of smell.

No male predominance in offspring of women with rheumatoid arthritis or systemic lupus erythematosus.

To assess the proportion of male versus female offspring of women diagnosed with SLE or RA, disorders in which female predominance is well known and PsA a disease in which female dominance is less established. The study population encompassed all females aged 16-46, who were members of the Maccabi Health Services (MHS) throughout the period of 2000-2011 and had at least one pregnancy. Data were retrieved from the computerized database of MHS, a 2-million enrollee health maintenance organization operating in Israel. The database was also used to collect data on patients with RA, SLE, and PsA. A total of 182,073 women had at least one indication of pregnancy during the study period. Among them, 546, 270, and 170 were diagnosed with RA, SLE, and PsA, respectively. The proportion of live-born males in 380,472 offspring of women free of these diseases was 51.5 % (95 % CI 51.4-51.7 %). The proportion (95 % CIs) of male offspring born to mothers diagnosed with of RA, SLE, and PsA were 46.3 % (42.3-50.3 %), 51.8 % (46.6-57.0 %), and 50.6 % (42.8-58.5 %), respectively. Our findings support the primary contribution of the hormonal phenotype rather than the genetic phenotype on autoimmunity. Neither patients with SLE or RA differ from the general population by the sex of their offspring.

Role of defibrillation threshold testing during implantable cardioverter-defibrillator placement: data from the Israeli ICD Registry.

BACKGROUND: Defibrillation threshold (DFT) testing during placement of an implantable cardioverter-defibrillator (ICD) has been considered mandatory. Accumulating data suggest a more limited role for DFT. OBJECTIVE: The purpose of this study was to compare the outcome of ICD recipients who underwent DFT testing compared with those who did not. METHODS: In this prospective cohort analysis of patients who received an ICD between July 2010 and March 2013, we compared patients who underwent DFT testing and those who did not. Primary end-points were death and malignant ventricular arrhythmias. Secondary end-points included the composite end-points and inappropriate ICD discharges. RESULTS: Of the 3596 patients in the registry, 614 patients (17%) underwent DFT testing during ICD placement vs 2982 (83%) who did not. Variables associated with ICD testing were implantation for secondary prevention (relative risk [RR] 1.87), prior ventricular arrhythmias (RR 1.81), use of antiarrhythmic medication (RR 1.59), and sinus rhythm (RR 2.05). Factors predisposing against testing were cardiac resynchronization therapy defibrillator implantation (RR 0.56) and concomitant diuretic use (RR 0.71). ICD testing was not associated with 1-year mortality (5.3% vs 5.1%, P = .74), delivery of appropriate shocks (8.6% vs 5.6%, P = .16), combined outcomes of ventricular arrhythmias and death (12.9% vs 11.3%, P = .45), or inappropriate ICD discharges (3.9% vs 2.1%, P = .2) compared to no DFT testing. CONCLUSION: No significant differences in the incidence of mortality, malignant ventricular arrhythmias, or inappropriate ICD discharges were observed between patients who underwent DFT testing compared to those who did not. Our results may support avoiding DFT testing during ICD placement, but this requires confirmation by additional prospective studies.

Vitamin D inflammatory cytokines and coronary events: a comprehensive review.

Myocardial infarction (MI) is the most common cause of cardiac injury in the Western world. Cardiac injury activates innate immune mechanisms initiating an inflammatory reaction. Inflammatory cytokines and vascular cell adhesion molecules (VCAM) promote adhesive interactions between leukocytes and endothelial cells, resulting in the transmigration of inflammatory cells into the site of injury. Low vitamin D levels are associated with higher prevalence of cardiovascular risk factors and a higher risk of MI. In this paper, we examine the effects of short-term vitamin D supplementation on inflammatory cytokine levels after an acute coronary syndrome. We recruited patients arriving to the hospital with an acute MI. All patients received optimal medical therapy and underwent a coronary catheterization. Half of the patients were randomly selected and treated with a daily supplement of vitamin D (4,000 IU) for 5 days. A short course of treatment with vitamin D effectively attenuated the increase in circulating levels of inflammatory cytokines after an acute coronary event. Control group patients had increased cytokine and cellular adhesion molecules serum concentrations after 5 days, while the vitamin D-treated group had an attenuated elevation or a reduction of these parameters. There were significant differences in VCAM-1 levels, C-reactive protein, and interleukin-6. There were trends toward significance in interleukin-8 levels. There were no significant differences in circulating levels of intercellular adhesion molecule 1, E-selectin, vascular endothelial growth factor, and tumor necrosis factor-α. These findings provide information on the anti-inflammatory effects of vitamin D on the vascular system and suggest mechanisms that mediate some of its cardioprotective properties. There is place for further studies involving prolonged vitamin D treatment in patients suffering from ischemic heart disease.

Association of fibromyalgia characteristics in patients with non-metastatic breast cancer and the protective role of resilience.

Cancer patients often complain about weakness, fatigue, and pain. The aim of this study was to assess the features of the fibromyalgia syndrome (FMS) characteristics in patients with non-metastatic breast cancer. The study group included 40 women whose age ranged from 40 to 70 years with Stages 0-3 breast cancer. The control group included 40 healthy women matched by age. A diagnosis of FMS was established based on medical history, physical examination, and the Fibromyalgia Impact Questionnaire (FIQ). Pain measures and functional factors were evaluated by the Brief Pain Inventory and the Sheehan Questionnaire. Resilience was assessed by Antanovsky's Sense of Coherence Questionnaire. Psychiatric disturbances were tested by the MINI Questionnaire and Hamilton questionnaires for depression and anxiety. The prevalence of chronic pain was higher in the study group. Statistically significant differences were also found between the group regarding pain, fatigue, and functional measures. The prevalence of depressive or anxious mood, measured by the Hamilton questionnaires, was strongly related to FMS characteristics reflected by FIQ scores (r = 0.79 between FIQ and the Hamilton Depression Index and r = 0.75 between FIQ and the Hamilton Anxiety Scale). The sense of coherence measure for these patients demonstrated an inverse correlation with pain, fatigue, and functional capability. Women with breast cancer tend to develop chronic widespread pain syndromes more often than do healthy women.

Effects of tobacco smoke on immunity, inflammation and autoimmunity.

Smoking is a central factor in many pathological conditions. Its role in neoplasm, lung and cardiovascular diseases has been well established for years. However it is less acknowledged the cigarette smoking affects both the innate and adoptive immune arms. Cigarette smoke was shown to augment the production of numerous pro-inflammatory cytokines such as TNF-alpha, IL-1, IL-6, IL-8 GM-CSF and to decrease the levels of anti-inflammatory cytokines such as IL-10. Tobacco smoke via multiple mechanisms leads to elevated IgE concentrations and to the subsequent development of atopic diseases and asthma. Cigarette smoke has also been shown activate in many ways macrophage and dendritic cell activity. While it is better evident how cigarette smoke evokes airway diseases more mechanisms are being revealed linking this social hazard to autoimmune disorders, for instance via the production of antibodies recognizing citrullinated proteins in rheumatoid arthritis or by the elevation of anti-dsDNA titers in systemic lupus erythematosus. The current review underlines the importance of smoking prevention and eradication not only in respiratory disorders but also in autoimmune conditions as well.

Screening for common neurologic diseases among Israeli adolescents.

Neurologic disorders are the common causes of morbidity among adolescents. The estimated prevalence of common neurologic disorders relies on relatively small samples. We aimed to identify the prevalence of common neurologic disorders among Israeli adolescents. In Israel, all 17-year-old Israeli nationals are required to undergo a health-screening examination at the Israel Defense Forces recruiting office. Neurology specialists evaluate and classify suspected neurologic disorders. The findings included a high prevalence of neurologic morbidity among the 94 805 adolescents (61.5% males and 39.5% females) examined in 2001. The most prevalent diagnoses were headaches and learning disorders. The frequency of chronic headache in this study was relatively low. A significant difference in morbidity patterns between male and female adolescents was noted. Overall, we found that the prevalence of chronic, frequent headaches among adolescents is much lower than that reported previously. Headache, learning disability, epilepsy, and infectious or traumatic head injury were the most common diagnoses.

Pneumatosis intestinalis presenting in autoimmune diseases: a report of three patients.

Pneumatosis intestinalis (PI) is an uncommon condition characterized by the presence of gas within the wall of the gastrointestinal tract. PI is a physical or imaging finding that is the result of an underlying pathological process or a disease. This finding may present in diverse conditions, such as obstructive pulmonary disease and intestinal disease, including obstruction, inflammation, or ischemia. PI has also been reported in different autoimmune conditions, especially in systemic sclerosis and rarely with systemic lupus erythematosus. In this report we present PI occurring in three patients with different autoimmune conditions and review the literature.

The role of infections in the immunopathogensis of systemic sclerosis--evidence from serological studies.

Infections are believed to often play a role in the immunopathogenesis of autoimmune disorders; such is the case in systemic sclerosis (SSc). In order to evaluate the potential role infections may have on the pathogenesis of SSc, we assessed serological reactivity against various infectious agents in patients with SSc and compared them with healthy controls. Serological samples obtained from 80 patients with SSc were compared with 296 compatible healthy controls. Both groups were of European origin. All samples were tested for the presence of antibodies directed against hepatitis B virus, hepatitis C virus, toxoplasmosis, rubella, CMV, EBV, and Treponema pallidum. We applied Bio-Rad commercial and experimental kits to assess most antigens and ELISA assays to complete the panel. Patients with SSc had elevated IgM and IgG against Toxoplasma gondii and against CMV. Higher titers were also detected against the hepatitis B virus core protein (recombinant HBc antigen) using MONOLISA anti-HBc Plus commercial kit (Bio-Rad). A significantly higher rate of IgM antibodies against the capsid antigen of the EBV was detected in SSc patients compared with healthy controls, as well. These data demonstrate that antibodies against CMV, HBV, and toxoplasmosis were detected more often in patients with SSc. This association implies that infectious agents may have a role in disease pathogenesis and expression.
