    Cardiac failure, such as myocardial infarction (MI), is one of the most serious causes of mortality worldwide. MI is the sign of cardiac cell damage as a result of decreased blood oxygen level, which causes some morphological changes in the form of 12-lead electrocardiogram (ECG) waves including T-wave, Q-wave, and ST-segment. The main goal of this study is to represent vectorcardiography (VCG) as a complementary diagnostic tool of the ECG method to discriminate the various type of MI from normal cases. The system proposed in this study was analysed on the Physikalisch-Technische Bundesanstalt diagnostic ECG database and a recorded signal database for 80 MI and 52 healthy cases. Each record consists of 15 ECG and VCG signals. In this study, tridimensional morphological features were applied to the classification and regression tree (CART) and the feedforward neural network classifier. To classify MI cases from healthy control cases of our recorded database, classification and regression tree achieved the same results when VCG features or ECG features were applied with an accuracy of 99.4, a sensitivity of 100, and a specificity of 98.7. Further, by using VCG Octant features with this current method, anterior-MI and inferior-MI were separated with an accuracy of 98.9, a sensitivity of 98, and a specificity of 100. The outcomes prove that the VCG features performed more accurately than ECG features in MI localisation

    Background: We sought to estimate the prevalence of diabetes mellitus (DM) and pre-DM and their associated factors among a sample of the Iranian urban population between 2017 and 2019. Methods: The present investigation is a sub-study on the HAMRAH cohort study, a longitudinal population-based cohort study to assess the 10-year risk of cardiovascular diseases and their related risk factors in the adult population of the Iranian capital, Tehran. Via a multistage cluster randomized sampling method, 2123 adults aged between 30 and 75 years who had no history of cardiovascular diseases were selected for the study. With the aid of the 2010 American Diabetes Association criteria for the definition of DM and pre-DM, age and sex-specific prevalence rates were estimated. Results: The estimated overall prevalence of DM was 14.3 (95 CI: 13.1�15.8): 10.4 known DM (95 CI: 9.1�11.8) and 4 newly diagnosed DM (95 CI: 3.1�5.1). Pre-DM was detected in about 29.2 of the study participants (95 CI: 22.9�36.3). Our logistic regression analysis revealed that increasing age, higher systolic blood pressure, higher levels of triglycerides, and lower levels of high-density lipoprotein were significantly associated with DM. Conclusions: DM and pre-DM follow a notable incremental pattern among the Iranian urban population. This finding underscores the significance of the need to improve prevention and screening strategies in the Iranian urban population. © 2021 Primary Care Diabetes Europ

    Purpose: High mortality and a limited performance of valvular surgery are typical features of infective endocarditis (IE) in octogenarians, even though surgical treatment is a major determinant of a successful outcome in IE. Methods: Data from the prospective multicentre ESC EORP EURO-ENDO registry were used to assess the prognostic role of valvular surgery depending on age. Results: As compared to < 80 yo patients, ≥ 80 yo had lower rates of theoretical indication for valvular surgery (49.1% vs. 60.3%, p < 0.001), of surgery performed (37.0% vs. 75.5%, p < 0.001), and a higher in-hospital (25.9% vs. 15.8%, p < 0.001) and 1-year mortality (41.3% vs. 22.2%, p < 0.001). By multivariable analysis, age per se was not predictive of 1-year mortality, but lack of surgical procedures when indicated was strongly predictive (HR 2.98 [2.43–3.66]). By propensity analysis, 304 ≥ 80 yo were matched to 608 < 80 yo patients. Propensity analysis confirmed the lower rate of indication for valvular surgery (51.3% vs. 57.2%, p = 0.031) and of surgery performed (35.3% vs. 68.4%, p < 0.0001) in ≥ 80 yo. Overall mortality remained higher in ≥ 80 yo (in-hospital: HR 1.50[1.06–2.13], p = 0.0210; 1-yr: HR 1.58[1.21–2.05], p = 0.0006), but was not different from that of < 80 yo among those who had surgery (in-hospital: 19.7% vs. 20.0%, p = 0.4236; 1-year: 27.3% vs. 25.5%, p = 0.7176). Conclusion: Although mortality rates are consistently higher in ≥ 80 yo patients than in < 80 yo patients in the general population, mortality of surgery in ≥ 80 yo is similar to < 80 yo after matching patients. These results confirm the importance of a better recognition of surgical indication and of an increased performance of surgery in ≥ 80 yo patients

    Characteristics, management, and outcomes of patients with left-sided infective endocarditis complicated by heart failure: a substudy of the ESC-EORP EURO-ENDO (European infective endocarditis) registry

    Aims: To evaluate the current management and survival of patients with left-sided infective endocarditis (IE) complicated by congestive heart failure (CHF) in the ESC-EORP European Endocarditis (EURO-ENDO) registry. Methods and results: Among the 3116 patients enrolled in this prospective registry, 2449 (mean age: 60years, 69% male) with left-sided (native or prosthetic) IE were included in this study. Patients with CHF (n = 698, 28.5%) were older, with more comorbidity and more severe valvular damage (mitro-aortic involvement, vegetations >10 mm and severe regurgitation/new prosthesis dehiscence) than those without CHF (all p ≤ 0.019). Patients with CHF experienced higher 30-day and 1-year mortality than those without (20.5% vs. 9.0% and 36.1% vs. 19.3%, respectively) and CHF remained strongly associated with 30-day (odds ratio[OR] 2.37, 95% confidence interval [CI] [1.73-3.24; p < 0.001) and 1-year mortality (hazard ratio [HR] 1.69, 95% CI 1.39-2.05; p < 0.001) after adjustment for established outcome predictors, including early surgery, or after propensity matching for age, sex, and comorbidity (n = 618 [88.5%] for each group, both p < 0.001). Early surgery, performed on 49% of these patients with IE complicated by CHF, remained associated with a substantial reduction in 30-day mortality following multivariable analysis, after adjustment for age, sex, Charlson comorbidity index, cerebrovascular accident, Staphylococcus aureus IE, streptococcal IE, uncontrolled infection, vegetation size >10 mm, severe valvular regurgitation and/or new prosthetic dehiscence, perivalvular complication, and prosthetic IE (OR 0.22, 95% CI 0.12-0.38; p < 0.001) and in 1-year mortality (HR 0.29, 95% CI 0.20-0.41; p < 0.001). Conclusion: Congestive heart failure is common in left-sided IE and is associated with older age, greater comorbidity, more advanced lesions, and markedly higher 30-day and 1-year mortality. Early surgery is strongly associated with lower mortality but is performed on only approximately half of patients with CHF, mainly because of a surgical risk considered prohibitive

    Aims: The EURO-ENDO registry aimed to study the management and outcomes of patients with infective endocarditis (IE). Methods and results: Prospective cohort of 3116 adult patients (2470 from Europe, 646 from non-ESC countries), admitted to 156 hospitals in 40 countries between January 2016 and March 2018 with a diagnosis of IE based on ESC 2015 diagnostic criteria. Clinical, biological, microbiological, and imaging [echocardiography, computed tomography (CT) scan, 18F-fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG PET/CT)] data were collected. Infective endocarditis was native (NVE) in 1764 (56.6%) patients, prosthetic (PVIE) in 939 (30.1%), and device-related (CDRIE) in 308 (9.9%). Infective endocarditis was community-acquired in 2046 (65.66%) patients. Microorganisms involved were staphylococci in 1085 (44.1%) patients, oral streptococci in 304 (12.3%), enterococci in 390 (15.8%), and Streptococcus gallolyticus in 162 (6.6%). 18F-fluorodeoxyglucose positron emission tomography/computed tomography was performed in 518 (16.6%) patients and presented with cardiac uptake (major criterion) in 222 (42.9%) patients, with a better sensitivity in PVIE (66.8%) than in NVE (28.0%) and CDRIE (16.3%). Embolic events occurred in 20.6% of patients, and were significantly associated with tricuspid or pulmonary IE, presence of a vegetation and Staphylococcus aureus IE. According to ESC guidelines, cardiac surgery was indicated in 2160 (69.3%) patients, but finally performed in only 1596 (73.9%) of them. In-hospital death occurred in 532 (17.1%) patients and was more frequent in PVIE. Independent predictors of mortality were Charlson index, creatinine > 2 mg/dL, congestive heart failure, vegetation length > 10 mm, cerebral complications, abscess, and failure to undertake surgery when indicated. Conclusion: Infective endocarditis is still a life-threatening disease with frequent lethal outcome despite profound changes in its clinical, microbiological, imaging, and therapeutic profiles

    International audienceAims - Infective endocarditis (IE) is a life-threatening disease associated with high mortality and morbidity worldwide. We sought to determine how socioeconomic factors might influence its epidemiology, clinical presentation, investigation and management, and outcome, in a large international multicentre registry. Methods and results - The EurObservational Programme (EORP) of the European Society of Cardiology EURO-ENDO (European Infective Endocarditis) registry comprises a prospective cohort of 3113 adult patients admitted for IE in 156 hospitals in 40 countries between January 2016 and March 2018. Patients were separated in three groups, according to World Bank economic stratification [group 1: high income (75.6%); group 2: upper-middle income (15.4%); group 3: lower-middle income (9.1%)]. Group 3 patients were younger [median age (interquartile range, IQR): group 1, 66 (53-75) years; group 2, 57 (41-68) years; group 3, 33 (26-43) years; P < 0.001] with a higher frequency of smokers, intravenous drug use, and human immunodeficiency virus infection (all P < 0.001) and presented later [median (IQR) days since symptom onset: group 1, 12 (3-35); group 2, 19 (6-54); group 3, 31 (12-62); P < 0.001] with a higher likelihood of developing congestive heart failure (13.6%, 11.1%, and 22.6%, respectively; P < 0.001) and persistent fever (9.8%, 14.2%, and 27.9%, respectively; P < 0.001). Among 2157 (69.3%) patients with theoretical indication for cardiac surgery, surgery was performed less frequently in group 3 patients (75.5%, 76.8%, and 51.3%, respectively; P < 0.001), who also demonstrated the highest mortality (15.0%, 23.0%, and 23.7%, respectively; P < 0.001). Conclusion - Socioeconomic factors influence the clinical profile of patients presenting with IE across the world. Despite younger age, patients from the poorest countries presented with more frequent complications and higher mortality associated with delayed diagnosis and lower use of surgery
