Abstract Background Beneficial effects of overweight and obesity on mortality after acute myocardial infarction (AMI) have been described as “Body Mass Index (BMI) paradox”. However, the effects of BMI is still on debate. We analyzed the association between BMI and 1-year major cardiocerebrovascular events (MACCE) after AMI. Methods and findings Among 13,104 AMI patients registered in an Institute of Health in Korea between November 2011 and December 2015, 10,568 patients who eligible for this study were classified into 3 groups according to BMI (Group I; <22 kg/m2, 22 ≤ Group II <26 kg/m2, Group III; ≥26 kg/m2). The primary end point was a composite of cardiac death (CD), myocardial infarction (MI), target vessel revascularization (TVR), and cerebrovascular events at 1 year. Over the median follow-up of 12 months, the composite of primary end point occurred more frequently in the Group I patients than in the Group III patients (primary endpoint: adjusted hazard ratio [aHR], 1.290; 95% confidence interval [CI] 1.024 to 1.625, p=0.031). Especially, cardiac death in MACCE components played a major role in this effect (aHR, 1.548; 95% confidence interval [CI] 1.128 to 2.124, p=0.007). Conclusions Higher BMI appeared to be good prognostic factor on 1-year MACCE after AMI. This result suggests that higher BMI or obesity might confer a protective advantage over the life-quality after AMI.

Background: Body mass index (BMI) is a critical determinant of mortality after acute myocardial infarction (AMI), and higher BMI is associated with survival benefit in patients with renal impairment. However, there are no studies investigating the interactive effects of BMI and renal function on mortality risk after AMI occurrence.Methods: We enrolled 12,647 AMI patients from Korea Acute Myocardial Infarction Registry between November 2011 and December 2015. Patients were categorized based on estimated Glomerular Filtration Rate (eGFR) and BMI. The primary endpoint was all-cause mortality after AMI treatment.Results: Within each renal function category, the absolute mortality rate was decreased in patients with higher BMI. However, the adjusted hazard ratio (HR) of all-cause mortality for higher BMI was decreased as renal function worsened [adjusted HR (95% confidence interval) at BMI ≥ 25 kg/m2: 0.63 (0.41–0.99), 0.76 (0.59–0.97), and 0.84 (0.65–1.08) for patients with eGFR ≥ 90, 90–45, and <45 mL/min/1.73 m2, respectively]. There was a significant interaction between BMI and renal function (P for interaction = 0.010). The protective effect of higher BMI was preserved against non-cardiac death and it was also decreased with lowering eGFR in competing risks models [adjusted HR at BMI ≥25 kg/m2: 0.38 (0.18–0.83), 0.76 (0.59–0.97), and 0.84 (0.65–1.08) for patients with eGFR ≥ 90, 90–45, and <45 mL/min/1.73 m2, respectively; P for interaction = 0.03]. However, renal function did not significantly affect the association between BMI and risk of cardiac death (P for interaction = 0.20).Conclusions: The effect of BMI on the mortality risk after AMI was dependent on renal function. The association between greater BMI and survival benefit was weakened as renal function was decreased. In addition, the negative effect of renal function on the BMI – mortality association was pronounced in the non-cardiac death.

Background: Periodontal disease has been reported to play a causative role in acute myocardial infarction (AMI), which may add to the various risk factors associated with coronary heart disease. The objective of the present study was to investigate the presence of Prevotella intermedia – an established periodontal pathogen – in subgingival plaque samples of chronic periodontitis and AMI patients in order to identify a possible association, and to evaluate the susceptibility of Prevotella intermedia to nine antimicrobial agents. Methods: After undergoing screening for eligibility, a total of 50 subjects were included in the present study. Twenty patients were diagnosed with AMI and generalized chronic periodontitis (Group I), 20 patients were diagnosed with only AMI (Group II), and 10 subjects were healthy controls (Group III). The isolated Prevotella intermedia strains were tested for susceptibility to bacitracin, chloramphenicol, penicillin G, polymyxin, gentamycin, neomycin, tetracycline, cefotaxime, and cefoxitin using an antibiotic zonescale to determine minimum inhibitory concentrations (MICs). Results: Periodontal pathogens were identified by phenotypic and enzymatic methods. The mean bacterial load of Prevotella intermedia species was higher in Group I compared to Group II and Group III. It was also found that pencillin G, gentamycin, neomycin, tetracycline, cefotaxime, and cefoxitin inhibited 90% of Prevotella intermedia, whereas bacitracin, chloramphenicol, and polymyxin inhibited 80% of Prevotella intermedia. Thus, only 10% of Prevotella intermedia were resistant to these antibiotics. Conclusion: The present study confirms that Prevotella intermedia is associated with chronic periodontitis and AMI.

Abstract We immunochemically measured lactate dehydrogenase isoenzyme 1 (LD-1), calculated LD-1/LD ratios (% LD-1) for 122 specimens from 60 patients, and compared the results with those for the conventional cardiac profile and other findings such as clinical presentation and electrocardiogram. Results for LD-1 and % LD-1 could be classified into three groups: group I, with LD-1 less than 64 U/L; group II, with LD-1 greater than 64 U/L and % LD-1 between 17 and 37%; and group III, with LD-1 greater than 64 U/L and 5 LD-1 greater than 38%. These three groups correlated closely and consistently with three patients of cardiac profile, i.e., those of no acute myocardial infarct, myocardial ischemia, and acute myocardial infarct, respectively.

Introduction. An important reserve that provides adaptation processes in the immunoregulation system is the possibility of its various subsystems to redistribute structural and functional relationships between them. The approach from the perspective of systemic multivariate analysis will allow us to determine the main functional relationships that arise or are violated at different periods of traumatic disease in patients with an increased body mass index (IBMI) during polytrauma in the immune response as a whole. Aim. The aim of this study was to analyze the functional state of the immunological protection system for traumatic disease in patients with IBMI. Materials and methods The integral indicators of immunogenesis were determined using a systematic multivariate analysis on the basis of a dynamic study of 1344 complex immunograms in 224 patients with IBMI with polytrauma and a different initial value of BMI. Patients were divided into 3 groups: group I - 88 patients with BMI of up to 29.9 (26.1 ± 3.1); group II - 84 patients with BMI of up to 30.0 - 39.9 (35.2 ± 3.8 ), group III - 52 patients with BMI > 40.0 (46.2 ± 5.8). The study was conducted on the 1st, 3rd, 7th, 14th, 30th and 360th days from the moment of receiving a polytrauma. Results. In the functional state of the immune system as a whole, certain regularities were identified in patients with IBMI with polytrauma: impairment of immunoreactive processes was prolonged for 1 year or more from the time of polytrauma, regardless of BMI, their nature is regular and unidirectional, have periods of decline and increase in activity; the degree of damage, the ability of compensatory possibilities and the ability to restore them depending on BMI, since the initial deviations of the integral indicator are almost identical in all groups of patients; the immune mechanisms at all times are most determined by the state of the cell link and complement system for patients of I and III groups. Moreover, the development mechanism of secondary post-traumatic immunodeficiency, which is associated with the inclusion of extended T-suppression and a decrease in IgA concentration for more than 14 days, depends on BMI; a clear cooperation of cellular and humoral relationships, which is aimed at compensating for its consequences, was determined in patients of group II as well as active participation in the immune reactions of HLA-DR + lymphocytes as a delicate adaptation mechanism. The development of functional instability of the system occurred mainly due to the T-cell link a year after the case of polytrauma. Conclusion. Our analysis made it possible to prove objectively on mathematical models that traumatic disease is a long process. Clinical and pathogenetic aspects of immune disorders are beyond question and provide the basis for the application of the proposed treatment algorithms and changes in stereotypes regarding the treatment approach as a whole.
