Lipoprotein-Associated Phospholipase A2 Bound on High-Density Lipoprotein Is Associated With Lower Risk for Cardiac Death in Stable Coronary Artery Disease Patients A 3-Year Follow-Up
ObjectivesThe aim of this study was to examine the prognostic value of lipoprotein-associated phospholipase A2 (Lp-PLA2) associated with high-density lipoprotein (HDL) (HDL-Lp-PLA2) in patients with stable coronary artery disease (CAD).BackgroundLp-PLA2 is a novel risk factor for cardiovascular disease. It has been postulated that the role of Lp-PLA2 in atherosclerosis may depend on the type of lipoprotein with which it is associated.MethodsTotal plasma Lp-PLA2 and HDL-Lp-PLA2 mass and activity, lipids, and C-reactive protein were measured in 524 consecutive patients with stable CAD who were followed for a median of 34 months. The primary endpoint was cardiac death, and the secondary endpoint was hospitalization for acute coronary syndromes, myocardial revascularization, arrhythmic event, or stroke.ResultsFollow-up data were obtained from 477 patients. One hundred twenty-three patients (25.8%) presented with cardiovascular events (24 cardiac deaths, 47 acute coronary syndromes, 28 revascularizations, 22 arrhythmic events, and 2 strokes). Total plasma Lp-PLA2 mass and activity were predictors of cardiac death (hazard ratio [HR]: 1.013; 95% confidence interval [CI]: 1.005 to 1.021; p = 0.002; and HR: 1.040; 95% CI: 1.005 to 1.076; p = 0.025, respectively) after adjustment for traditional risk factors for CAD. In contrast, HDL-Lp-PLA2 mass and activity were associated with lower risk for cardiac death (HR: 0.972; 95% CI: 0.952 to 0.993; p = 0.010; and HR: 0.689; 95% CI: 0.496 to 0.957; p = 0.026, respectively) after adjustment for traditional risk factors for CAD.ConclusionsTotal plasma Lp-PLA2 is a predictor of cardiac death, while HDL-Lp-PLA2 is associated with lower risk for cardiac death in patients with stable CAD, independently of other traditional cardiovascular risk factors
A case-control validation of Type D personality in Greek patients with stable coronary heart disease
BACKGROUND: Type D personality has been associated with a variety of emotional and social difficulties as well as with poor prognosis in patients with established coronary heart disease (CHD). We examined the psychometric properties and validity of the Type D Scale-14 (DS14) and the prevalence of Type D personality among Greek patients with CHD while taking into account demographic; clinical, such as diabetes mellitus, hypertension, and hypercholesterolemia; as well as psychological variables such as depression, anxiety, and psychological stress. METHODS: Ninety-six patients with stable coronary heart disease and 80 healthy participants from the general population completed the Greek version of the DS14 and the Hospital Anxiety and Depression Scale (HADS). RESULTS: Cronbach's α coefficient for the negative affectivity (NA) and social inhibition (SI) subscales was 0.83 and 0.72 for the CHD and 0.88 and 0.76 for the control group, respectively. Internal-structural validity was assessed by a factor analysis (two-factor solution), and the factor structure of the original DS14 was replicated. Using the standardized cutoff point of NA ≥10 and SI ≥10, instead of the median scores, in order to have compatible results with the majority of studies, the prevalence of Type D personality was 51% for the CHD patients and 13% for the control group. Higher NA and SI were connected with higher anxiety, depression, and total psychological stress. Finally, more patients with CHD and Type D personality than those without were diagnosed with type 2 diabetes; however, no differences were observed in hypertension or hypercholesterolemia. CONCLUSIONS: These results indicate that the Type D construct is reliable and valid in a Greek population. The prevalence of Type D personality was higher in patients with stable coronary heart disease than in people from the general population. The DS14 subscales were positively correlated with higher anxiety, depression, and total psychological stress. Regarding other CHD risk factors, only diabetes mellitus was found more frequently in CHD patients with Type D personality
European Society of Cardiology: Cardiovascular Disease Statistics 2017
Background: The European Society of Cardiology (ESC) Atlas has been compiled by the European Heart Agency to document cardiovascular disease (CVD) statistics of the 56 ESC member countries. A major aim of this 2017 data presentation has been to compare high income and middle income ESC member countries, in order to identify inequalities in disease burden, outcomes and service provision. Methods: The Atlas utilizes a variety of data sources, including the World Health Organization, the Institute for Health Metrics and Evaluation, and the World Bank to document risk factors, prevalence and mortality of cardiovascular disease and national economic indicators. It also includes novel ESC sponsored survey data of health infrastructure and cardiovascular service provision provided by the national societies of the ESC member countries. Data presentation is descriptive with no attempt to attach statistical significance to differences observed in stratified analyses. Results: Important differences were identified between the high income and middle income member countries of the ESC with regard to CVD risk factors, disease incidence and mortality. For both women and men, the age-standardised prevalence of hypertension was lower in high income countries (18.3% and 27.3%) compared with middle income countries (23.5% and 30.3%). Smoking prevalence in men (not women) was also lower (26% vs 41.3%), and together these inequalities are likely to have contributed to the higher CVD mortality in middle income countries. Declines in CVD mortality have seen cancer becoming a more common cause of death in a number of high income member countries, but in middle income countries declines in CVD mortality have been less consistent where CVD remains the leading cause of death. Inequalities in CVD mortality are emphasised by the smaller contribution they make to potential years of life lost in high income compared with middle income countries both for women (13% vs. 23%) and men (20% vs. 27%). The downward mortality trends for CVD may, however, be threatened by the emerging obesity epidemic that is seeing rates of diabetes increasing across all ESC member countries. Survey data from the National Cardiac Societies (n=41) showed that rates of cardiac catheterization and coronary artery bypass surgery, as well as the number of specialist centres required to deliver them, were greatest in the high income member countries of the ESC. The Atlas confirmed that these ESC member countries, where the facilities for the contemporary treatment of coronary disease were best developed, were often those in which declines in coronary mortality have been most pronounced. Economic resources were not the only driver for delivery of equitable cardiovascular healthcare, as some middle income ESC member countries reported rates for interventional procedures and device implantations that matched or exceeded the rates in wealthier member countries. Conclusion: In documenting national CVD statistics, the Atlas provides valuable insights into the inequalities in risk factors, healthcare delivery and outcomes of CVD across ESC member countries. The availability of these data will underpin the ESC’s ambitious mission “to reduce the burden of cardiovascular disease” not only in its member countries, but also in nation states around the world
The prognostic significance of atrial arrhytmias recorded early after cardioversion for atrial fibrillation

Laparoscopic sleeve gastrectomy in morbidly obese patients. Technique and short term results
Objective : To evaluate the efficacy of Laparoscopic Sleeve Gastrectomy
(LSG) as a definitive procedure for morbidly obese patients. Design :
This constitutes a prospective study carried out in a tertiary care
private hospital and included 15 morbidly obese patients who underwent
LSG. The operation was performed through two 12 mm and two 5 mm ports,
using the Endo-GIA stapler to create a lesser curve gastric tube over a
36-Fr bougie. Results : Operative time, complication rates, hospital
length of stay, Body Mass Index (BMI), % of Excess Weight Loss (EWL)
and appetite were evaluated. There were six females and nine males, aged
(mean +/- SD) 40.5 +/- 10.5 yrs and preoperative BMI 47.8 +/- 7.5
kg/m(2). The operative time was 147.7 +/- 43.2 min. There was one
conversion to open surgery and one gastric leak with haemorrhage that
led to gastric tube stenosis, ultimately requiring revision surgery. All
patients, except these two, were discharged on the 2nd postoperative day
after an upper GI series and the initiation of a clear liquid diet. At
the follow-up (7.5 +/- 4.4 months post operatively), the % EWL was 35.7
+/- 10.1. Eight patients who received regular postoperative dietician
counselling at follow-up did better than the others who did not (% EWL
40.4 +/- 3.8 vs 30.2 +/- 4.1, respectively). All patients reported
significant loss of appetite. Conclusions : Although the number of
patients is relatively small, the data of this study indicate that
laparoscopic sleeve gastrectomy is effective in weight reduction, being
an acceptable surgical option for morbidly obese patients. A higher
number of patients and longer follow-up period will be necessary to
evaluate long-term efficacy
Evaluation of the medication process in pediatric patients: a meta-analysis
OBJECTIVE: to meta-analyze studies that have assessed the medication errors rate in pediatric patients during prescribing, dispensing, and drug administration. SOURCES: searches were performed in the PubMed, Cochrane Library, and Trip databases, selecting articles published in English from 2001 to 2010. SUMMARY OF THE FINDINGS: a total of 25 original studies that met inclusion criteria were selected, which referred to pediatric inpatients or pediatric patients in emergency departments aged 0-16 years, and assessed the frequency of medication errors in the stages of prescribing, dispensing, and drug administration. CONCLUSIONS: the combined medication error rate for prescribing errors to medication orders was 0.175 (95% Confidence Interval: [CI] 0.108-0.270), the rate of prescribing errors to total medication errors was 0.342 (95% CI: 0.146-0.611), that of dispensing errors to total medication errors was 0.065 (95% CI: 0.026-0.154), and that ofadministration errors to total medication errors was 0.316 (95% CI: 0.148-0.550). Furthermore, the combined medication error rate for administration errors to drug administrations was 0.209 (95% CI: 0.152-0.281). Medication errors constitute a reality in healthcare services. The medication process is significantly prone to errors, especially during prescription and drug administration. Implementation of medication error reduction strategies is required in order to increase the safety and quality of pediatric healthcare
Cardiovascular Hypertensive Crisis: Recent Evidence and Review of the Literature
Despite the high prevalence of hypertension (HTN), only a small
proportion of the hypertensive patients will ultimately develop
hypertensive crisis. In fact, some patients with hypertensive crisis do
not report a history of HTN or previous use of antihypertensive
medication. The majority of the patients with hypertensive crisis often
report non-specific symptoms, whereas heart-related symptoms (dyspnea,
chest pain, arrhythmias, and syncope) are less common. Hypertensive
crises can be divided into hypertensive emergencies or hypertensive
urgencies according to the presence or absence of acute target organ
damage, respectively. This differentiation is an extremely useful
classification in clinical practice since a different management is
needed, which in turn has a significant effect on the morbidity and
mortality of these patients. Therefore, it is very crucial for the
physician in the emergency department to identify the hypertensive
emergencies and to manage them through blood pressure lowering
medications in order to avoid further target organ damage or
deterioration. The aim of this narrative review is to summarize the
recent evidence in an effort to improve the awareness, recognition, risk
stratification, and treatment of hypertensive crisis in patients
referred to the emergency department
Low-Dose Dobutamine Stress Echocardiography for the Early Detection of Pulmonary Arterial Hypertension in Selected Patients with Systemic Sclerosis Whose Resting Echocardiography Is Non-Diagnostic for Pulmonary Hypertension
Background: Dobutamine stress echocardiography (DSE) has limited
application in systemic sclerosis (SSc). We examined DSE usefulness in
revealing pulmonary arterial hypertension (PAH) in selected SSc patients
whose resting echocardiography for pulmonary hypertension (PH) was
non-diagnostic. Methods: Forty SSc patients underwent right heart
catheterization (RHC) and, simultaneously, low-dose DSE (incremental
doses up to 20 mu g/kg/min). Inclusion criteria were: preserved left and
right ventricular (RV) function (tricuspid annulus plane systolic
excursion [TAPSE] >= 16 mm and tissue Doppler imaging-derived systolic
velocity of tricuspid annulus [RVS’] > 10 cm/s), normal pulmonary
function tests, and baseline maximal tricuspid regurgitation (TR)
velocity of 2.7-3.2 m/s. Results: Of 36 patients who completed DSE,
resting RHC diagnosed PAH in 12 patients (33.3%). At 20 mu g/kg/min,
patients with PAH had higher TR velocity, higher pulmonary arterial
pressure measured by RHC, and lower RV inotropic response compared with
patients without PAH. A cut-off value of maximal TR velocity >3.1 m/s
had a sensitivity of 80%, a specificity of 84.2%, and an accuracy of
82.4% for the detection of PAH. Conclusions: Low-dose DSE has a
satisfactory diagnostic accuracy for the early detection of PAH in
highly selected SSc patients whose baseline echocardiographic
measurements for PH lie in the gray zone
