RESUMO

Introduction: The accumulation of visceral abdominal tissue (VAT) seems to be a hallmark feature of abdominal obesity and substantially contributes to metabolic abnormalities. There are numerous factors that make the body-mass index (BMI) a suboptimal measure of adiposity. The visceral adiposity index (VAI) may be considered a simple surrogate marker of visceral adipose tissue dysfunction. However, the evidence comparing general to visceral adiposity in CAD is scarce. Therefore, we have set out to investigate visceral adiposity in relation to general adiposity in patients with stable CAD. Material and methods: A total of 204 patients with stable CAD hospitalized in the Department of Medicine and the Department of Geriatrics entered the study. Based on the VAI-defined adipose tissue dysfunction (ATD) types, the study population (N = 204) was divided into four groups: (1) no ATD (N = 66), (2) mild ATD (N = 50), (3) moderate ATD (N = 48), and (4) severe ATD (N = 40). Nutritional status was assessed using the Controlling Nutritional Status (CONUT) score. Results: Patients with moderate and severe ATD were the youngest (median 67 years), yet their metabolic age was the oldest (median 80 and 84 years, respectively). CONUT scores were similar across all four study groups. The VAI had only a modest positive correlation with BMI (r = 0.59 p < 0.01) and body adiposity index (BAI) (r = 0.40 p < 0.01). There was no correlation between VAI and CONUT scores. There was high variability in the distribution of BMI-defined weight categories across all four types of ATD. A total of 75% of patients with normal nutritional status had some form of ATD, and one-third of patients with moderate or severe malnutrition did not have any ATD (p = 0.008). In contrast, 55-60% of patients with mild, moderate, or severe ATD had normal nutritional status (p = 0.008). ROC analysis demonstrated that BMI and BAI have poor predictive value in determining no ATD. Both BMI (AUC 0.78 p < 0.0001) and BAI (AUC 0.66 p = 0.003) had strong predictive value for determining severe ATD (the difference between AUC 0.12 being p = 0.0002). However, BMI predicted mild ATD and severe ATD better than BAI. Conclusions: ATD and malnutrition were common in patients with CAD. Notably, this study has shown a high rate of misclassification of visceral ATD via BMI and BAI. In addition, we demonstrated that the majority of patients with normal nutritional status had some form of ATD and as much as one-third of patients with moderate or severe malnutrition did not have any ATD. These findings have important clinical ramifications for everyday practice regarding the line between health and disease in the context of malnutrition in terms of body composition and visceral ATD, which are significant for developing an accurate definition of the standards for the intensity of clinical interventions.

RESUMO

An 83-year-old man with a history of permanent atrial fibrillation (AF) anticoagulated by dabigatran 150 b.i.d., type 2 diabetes mellitus, and hypertension was admitted to the hospital with a diagnosis of ST-elevation myocardial infarction (STEMI). The patient was loaded with 300 mg of aspirin p.o., 5000 IU of unfractionated heparin i.v. and 600 mg of clopidogrel and was transferred to the catheterization laboratory. Coronary angiography demonstrated left anterior descending artery (LAD) occlusion. During the LAD angioplasty a dissection of a distal part of the LAD and the blood extravasation to the pericardium occurred (Figure 1 A). Idarucizumab 2 × 2.5 g i.v. was administered and the inflated balloon maintained at the site of coronary perforation. About 10 min after the end of idarucizumab infusion, the balloon was deflated and the patient presented with clinical symptoms of cardiac tamponade such as blood pressure decrease and tachycardia. The echocardiographic assessment revealed up to 16 mm accumulation of pericardial fluid (Figure 2 A). Immediately the covered stent was implanted (Papyrus, Biotronik) and the pericardiocentesis was carried out. 320 ml of blood was finally drained. Control contrast injection revealed a covered perforating zone with no contrast extravasation (Figure 1 B). The echocardiographic control revealed pericardial effusion less than 5 mm (Figure 2 B). The patient was stable with a blood pressure of 130/80 mm Hg, a heart rate of 100-130/min (AF), and without chest pain. No significant reduction in the red blood cell count was observed. Antiplatelet therapy was given consisting of aspirin and clopidogrel. In the following days enoxaparin was introduced and finally changed to dabigatran 110 mg b.i.d.

RESUMO

BACKGROUND AND AIMS: Body-mass index (BMI) is a popular method implemented to define weight status. However, describing obesity by BMI may result in inaccurate assessment of adiposity. The Body Adiposity Index (BAI) is intended to be a directly validated method of estimating body fat percentage. We set out to compare body weight status assessment by BMI and BAI in a cohort of elderly patients with stable coronary artery disease (CAD). METHODS: A total of 169 patients with stable CAD were enrolled in an out-patient cardiology clinic. The National Research Council (US) Committee on Diet and Health classification was used for individuals older than 65 years as underweight BMI < 24 kg/m2, normal weight BMI 24-29 kg/m2, overweight BMI 29-35 kg/m2, and obesity BMI > 35 kg/m2. In case of BAI, we used sex- and age-specific classification of weight status. In addition, body fat was estimated by bioelectrical impedance analysis (BImpA). RESULTS: Only 72 out of 169 patients (42.6%) had concordant classification of weight status by both BMI and BAI. The majority of the patients had their weight status either underestimated or overestimated. There were strong positive correlations between BMI and BImpA (FAT%) (R = 0.78 p < 0.001); BAI and BImpA (FAT%) (R = 0.79 p < 0.001); and BMI and BAI (R = 0.67 p < 0.001). BMI tended to overestimate the rate of underweight, normal weight or overweight, meanwhile underestimating the rate of obesity. Third, BMI exhibited an average positive bias of 14.4% compared to the reference method (BImpA), whereas BAI exhibited an average negative bias of -8.3% compared to the reference method (BImpA). Multivariate logistic regression identified independent predictors of discordance in assessing weight status by BMI and BAI: BImpA (FAT%) odds ratio (OR) 1.29, total body water (%) OR 1.61, fat mass index OR 2.62, and Controlling Nutritional Status (CONUT) score OR 1.25. CONCLUSIONS: There is substantial rate of misclassification of weight status between BMI and BAI. These findings have significant implications for clinical practice as the boundary between health and disease in malnutrition is crucial to accurately define criteria for intervention. Perhaps BMI cut-offs for classifying weight status in the elderly should be revisited.

RESUMO

BACKGROUND: No previous study has investigated the association between gamma glutamyltransferase (GGT) and vitamin D in patients with stable coronary artery disease (CAD). We investigated the cross-sectional associations between vitamin D status as assessed by serum 25(OH)D and GGT. METHODS: 169 patients were enrolled. Study population was divided into three groups: 1: 25(OH)D < 10 ng/mL (n = 59); 2: 25(OH)D 10-20 ng/mL (n = 82), and 3: 25(OH)D > 20 ng/mL (n = 28). Based on a cut-off GGT value identified in ROC analysis, we also divided the study population to compare the following groups: GGT ≤19 (n = 66) and GGT >19 (n = 103). RESULTS: GGT activity was the highest in vitamin D severely deficient patients and the lowest in vitamin D insufficient patients. GGT was inversely correlated with 25(OH)D concentrations (R = -0.23; p = 0.002). The receiver operating characteristics curve identified the discrimination threshold of GGT of >19 U/L in predicting vitamin D deficiency. Higher leukocyte and neutrophil counts and lower 25(OH)D concentration were found in patients with GGT > 19 U/L. CONCLUSIONS: We identified an interaction between declining 25(OH)D levels and rising GGT levels with increasing age, which resulted in an unfavorable 25(OH)D-to-GGT ratio in stable CAD patients. These results suggest that these changes might further contribute to a high cardiovascular risk in the elderly.

RESUMO

INTRODUCTION: There is a paucity of real­world registries concerning patients with chronic coronary syndromes (CCS). OBJECTIVES: We aimed to assess the long­term outcomes of patients with CCS and after coronary angiography performed in accordance with the treatment strategy. PATIENTS AND METHODS: The analysis involved 11 021 patients treated in a single center between 2006 and 2016 who were enrolled into the ongoing PRESAGE registry. Based on the results of coronary angiography and the treatment strategy adopted, patients were classified into 4 groups: with nonsignificant lesions (n = 3637), undergoing percutaneous coronary intervention (n = 4678), undergoing coronary artery bypass grafting (CABG; n = 997), and receiving conservative treatment (notwithstanding significant lesions on an angiogram; n = 1709). All­cause death, assessed in every study group at 1-, 3-, and 5­year follow­up, was regarded as the primary outcome measure. RESULTS: The mean (SD) age of the study patients was 64.6 (9.5) years, and women constituted 35% of the cohort. Patients treated conservatively were the oldest (mean [SD] age, 64.9 [9.3] years) in the group and showed the highest prevalence of previous myocardial infarction (50.5%), CABG (31.8%), diabetes (40.3%), chronic total occlusion (65.5%), and left ventricular ejection fraction below 35% (24.4%). Death from any cause in patients with nonsignificant lesions, undergoing percutaneous coronary intervention, undergoing CABG, and receiving conservative treatment occurred 5 years following the index hospitalization in 11.2%, 16.2%, 9.7%, and 21% of those patients, respectively. CONCLUSIONS: The PRESAGE registry provides valuable information about the clinical characteristics and long­term outcomes of patients with CCS. The population of CCS patients is heterogeneous, and long­term prognosis is also varied. The poorest characteristics and outcomes were reported in patients with significant lesions and ineligible for revascularization procedures.

RESUMO

There is little published data on the association of platelet function and 25(OH)D concentration. We investigated the associations between mean platelet volume (MPV) and 25(OH)D concentration in patients with stable coronary artery disease. Study population was divided into three groups: group 1-25(OH)D < 10 ng/mL (N = 22), group 2-25(OH)D 10-20 ng/mL (N = 42), and group 3-25(OH)D > 20 ng/mL (N = 14). Study groups shared similar demographics. MPV values were the highest in group 1, moderate in group 2, and the lowest in group 3 (11.1 vs 10.4 vs 9.8 fL P < 0.001). There was a negative correlation between MPV and 25(OH)D (R = - 0.38, P = 0.001). ROC analysis demonstrated a moderate predictive value (AUC 0.70) in identifying the discrimination thresholds of MPV (> 10.5 fL) for vitamin D deficiency and a weak predictive value (AUC 0.65) in identifying the discrimination thresholds of 25(OH)D concentration (≤ 15.5 ng/mL) for the presence of large platelets (MPV over the upper limit of normal). In conclusion, even though the effect of vitamin D on platelet size and function is probably multifactorial, our study provides further evidence linking vitamin D to thrombosis and hemostasis. Platelets are another potential element through which vitamin D deficiency could exert adverse cardiovascular outcomes.

RESUMO

Few reports have analyzed the effect of pentraxin 3 (PTX3) on platelets and their activation. We explored the association between plasma PTX3 and platelet indices. Forty-nine patients with stable coronary artery disease (CAD) were enrolled. Based on median PTX3, the study population was divided into group 1 (n = 25; PTX3 ≤ 0.98 ng/mL) and group 2 (n = 24; PTX3 > 0.98 ng/mL). Platelet indices investigated included mean platelet volume (MPV), platelet distribution width (PDW), platelets and large cell ratio (P-LCR), MPV to platelet count ratio (MPV/PC), platelet to lymphocyte ratio (PLR), and MPV to lymphocyte ratio (MPVLR). Patients with lower PTX3 had a higher lymphocyte count. Platelet count was similar in both groups. Notwithstanding, patients with higher PTX3 concentrations had elevated MPV (8.3 vs 10.0 fL; P < .001) and PDW (9.4 vs 12.4 fL; P < .001). However, the MPV/PC ratio was similar in both groups. Thromboinflammatory biomarkers (PLR, MPVLR) were also elevated in group 2. Pentraxin 3showed a strong, positive correlation with MPV ( r = .75, P < .01) and PDW ( r = .80, P < .01), and weak to moderate correlation with MPVLR. In conclusion, PTX3 is associated with larger platelet size as assessed by platelet volume indices. There is a strong correlation between plasma PTX3 level and MPV and PDW.

RESUMO

AIMS: Diabetes mellitus (DM) is one of the most frequently detected conditions in multimorbid disease clusters. Platelet activation is one of the key mechanisms underlying atherothrombosis in acute myocardial infarction. Available data link mean platelet volume (MPV) to poor prognosis not only in cardiovascular and non-cardiovascular disease. Given the lack of research data on the association between disease clusters and MPV, we have set out to investigate the link between multimorbidity and MPV in diabetic patients with acute myocardial infarction. METHODS: A total of 277 patients with DM and STEMI undergoing primary percutaneous coronary intervention were enrolled. Based on the number of comorbidities the study population was divided into two groups: group 1 (N = 58) with ≤ 1 comorbidity and group 2 (N = 219) with ≥ 2 comorbidities. A subanalysis was performed within the multimorbidity group: group 2A with two or three comorbidities (N = 156) and group 2B with at least four comorbidities (N = 63). RESULTS: In the study population, 15.9% of patients had one comorbidity, and 22.0, 34.3, and 22.7% of patients had two, three, or at least four comorbid conditions, respectively. Both MPV and PDW were elevated in multimorbid patients (9.3 vs 10.8 fl and 9.5 vs 10.3 fl, respectively). The highest platelet volume indices were observed in patients with at least four comorbid conditions. There was a moderate positive correlation between MPV and the total number of comorbidities, the number of CVD comorbidities, and the number of non-CVD comorbidities. CONCLUSIONS: These findings indicate that multimorbidity is associated with an increase in platelet volume indices. MPV values increased with the increasing number of comorbid conditions. Importantly, MPV values were elevated in some, but not all CVD and non-CVD conditions.

RESUMO

Introduction: There is an increasing body of evidence on the clinical importance of multimorbidity, which is defined as the coexistence of two or more chronic conditions. Type 2 diabetes (T2DM) is one of the most frequent chronic conditions. Most adults with type 2 diabetes have at least 1 coexisting chronic condition and approximately 40% have 3 or more. Prior studies have suggested that cardiovascular (CVD) and non-CVD comorbid conditions yield worse outcomes in patients hospitalized with ST-elevation myocardial infarction (STEMI). It is unclear, however, the extent to which multimorbidity has a cumulative effect on long-term risk. Therefore we have set out to determine the prognostic value of multiple comorbidity on long-term outcomes in this population of patients. Methods: A total of 277 patients with T2DM and STEMI undergoing primary percutaneous coronary intervention (PCI) were enrolled. Based on the number of comorbidities the study population was divided into two groups: group 1 (N=58) with ≤ 1 comorbidity and group 2 (N=219) with ≥ 2 comorbidities. Results: Comorbid conditions were prevalent among study participants (Figure 1). The median number of comorbidities was three. 15.9% of patients had one comorbidity and 22.0%, 34.3%, and 22.7% of patients had two, three or at least four comorbid conditions respectively. A majority of patients had at least one CVD comorbidity (6.1% of patients had none), whereas 53.1% of patients did not have any non-CVD comorbidity. During hospitalization 3 out of 58 patients (5.2%) died in group 1 and 25 of 219 patients (11.4%) died in group 2. The number of comorbid conditions was not an independent predictor of in-hospital death. During 12-month follow-up, 5 of 58 patients (8.6%) and 42 of 219 patients (19.9%) died, respectively in group 1 and 2 (P=0.05). The number of comorbid conditions proved in ROC analysis that for 12-month mortality, the prognostic value was modest, but for 12-month acute coronary syndromes the prognostic value was good. Increase in the number of comorbid conditions by one was associated with a 15% increase in the relative risk of 12-month mortality and a 41% increase in the relative risk of 12-month acute coronary syndromes (ACS). Conclusions: Comorbid conditions are highly prevalent among these groups of patients. Majority of patients have at least 2 other cardiovascular comorbidities and one or two non-cardiovascular comorbidities. In terms of long-term follow-up, multimorbidity was associated with worse outcomes. The risk of both long-term mortality and ACS increased with the increasing number of comorbidities. In summary, our findings highlight the importance of indentifying patients with multimorbidity. This, in turn, could allow for provision of better care to these high-risk and complex group of patients.

RESUMO

AIM: There has been a rise in contrast-induced acute kidney injury (CI-AKI). We examined the role of platelet-to-lymphocyte ratio (PLR) in predicting CI-AKI episodes in patients with myocardial infarction (MI) and diabetes. METHODS: A total of 719 patients with diabetes and MI were enrolled. Study population was divided into: group 1 (n = 615) without CI-AKI and group 2 (n = 104) with CI-AKI. RESULTS: Patients with CI-AKI had higher in-hospital mortality and a longer in-hospital stay. Median PLR was higher in patients with CI-AKI. Receiver operating characteristic analysis indicated PLR to be a good predictive tool in assessing the risk of CI-AKI. PLR was an independent predictor of CI-AKI (OR: 1.22; p < 0.0001). CONCLUSION: These results suggest potential role for PLR as a biomarker of CI-AKI among diabetic patients with MI who undergo percutaneous coronary intervention.

RESUMO

Trimetazidine (TMZ) exhibits metabolic and cardioprotective effects. The aim of this study was to assess the effects of TMZ on interleukin-2 (IL-2) and interleukin-8 (IL-8) serum concentrations in 156 patients with stable coronary artery disease. They underwent a treadmill exercise test (TET) before and after 3 months of TMZ treatment. IL-2 and IL-8 concentrations were determined before and after each TET. Before treatment, TET did not influence IL-2 concentrations, whereas IL-8 concentrations increased. TMZ treatment led to a decrease in IL-2 concentrations before TET, as well as it prevented the increase of IL-8 following the second TET. Obtained results confirmed the improvement in TET performance during TMZ treatment and they revealed a significant influence of TMZ on IL-2 and IL-8 concentrations both before and after TET. These changes may reflect potential anti-inflammatory effects of TMZ.

RESUMO

AIM: We investigated prognostic value of novel simplified thrombo-inflammatory score (sTIPS) in patients with ST-elevation myocardial infarction (STEMI) and diabetes mellitus. METHODS: A total of 465 patients with diabetes mellitus and STEMI were included in the study. Based on admission cut-off values for predicting in-hospital mortality of white blood cell count (>13.4 × 103/mm3) and mean platelet volume-to-platelet count ratio (>0.06), the patients were assigned 0 point for having the lower value of each variable and 1 point for having the upper value of each variable. sTIPS was calculated as the sum of these two variables. RESULTS: Kaplan-Meier curves demonstrated that higher sTIPS categories were associated with higher in-hospital and 12-month mortality. One-point increment in the score was associated with 51% increase in the risk of in-hospital death and 89% increase in the risk of long term. CONCLUSION: sTIPS is useful in predicting worse immediate and long-term outcomes following STEMI.

RESUMO

AIMS: TIMI risk score and GRACE risk model are widely available and accepted scores for risk assessment in STEMI patients and include predictors of poor outcomes. CHA2DS2-VASc is a validated score for predicting embolic/stroke risk in patients with non-valvular atrial fibrillation. Its components contribute to the worse prognosis following myocardial infarction. The advantage of the CHA2DS2-VASc score in comparison with other risk scores is that it provides a comprehensive, fast, and simple method for physicians in risk evaluation that requires no calculators or computers. Therefore, we have set out to examine the prognostic significance of CHA2DS2-VASc score following STEMI in diabetic patients without AF. METHODS: A total of 472 patients with diabetes mellitus and STEMI undergoing primary PCI were enrolled. Based on the estimated CHA2DS2-VASc score, the study population was divided into three groups: group 1 (N = 111) with a moderate CHA2DS2-VASc score of 2 or 3; group 2 (N = 257) with a high CHA2DS2-VASc score of 4 or 5; and group 3 (N = 104) with a very high CHA2DS2-VASc score of 6 or higher. RESULTS: In diabetic patients with STEMI, the median of CHA2DS2-VASc score was 4 (interquartile range 3-5). In-hospital mortality rate was similar across three groups. CHA2DS2-VASc score was not a risk factor of in-hospital mortality. ROC analysis revealed good diagnostic value of CHA2DS2-VASc score in predicting long-term mortality (AUC 0.62 95 % CI 0.57-0.66 P = 0.0003) and stroke (AUC 0.75 95 % CI 0.71-0.79 P = 0.0003), but no value in predicting long-term myocardial infarction. CHA2DS2-VASc score was an independent predictor of 12-month mortality and stroke. One-point increment in CHA2DS2-VASc score was associated with an increase in the risk of 12-month death by 24 % and for 12-month stroke by 101 %. CONCLUSIONS: In diabetic patients with STEMI and no previous AF, median CHA2DS2-VASc score was high (4 points) and predicted 12-month death and stroke. However, it failed to predict in-hospital death and 12-month MI. CHA2DS2-VASc score had a similar discrimination performance in predicting 12-month mortality as TIMI risk score and a better discrimination performance in predicting 12-month stroke than TIMI risk score. Thus, it can serve as an additive tool in identifying high-risk patients that require aggressive management.

RESUMO

INTRODUCTION: Platelet activation and hyperreactivity plays a pivotal role in developing intravascular thrombus in ST elevation myocardial infarction (STEMI). Mean platelet volume (MPV), which is readily available in clinical settings, has been linked to poor prognosis following STEMI. Recently, platelet-to-lymphocyte ratio (PLR) has emerged as a new marker of worse outcomes linking inflammation and thrombosis. We investigated the prognostic significance of the new marker, MPVLR, in diabetic patients with STEMI undergoing percutaneous coronary intervention (PCI). METHODS: A total of 623 patients with diabetes mellitus and STEMI undergoing primary PCI were enrolled and divided based on the median MPVLR on admission into two groups: group 1 (N=266) with an MPVLR ≤4.46 and group 2 (N=257) with an MPVLR >4,46. RESULTS: Despite similar clinical features patients with elevated MPVLR (group 2) had worse angiographic characteristic suggestive of a higher thrombus burden. In-hospital and one-year mortality was higher in group 2. ROC analysis revealed moderate diagnostic value in predicting in-hospital mortality (adjusted HR 1.13; 95% CI 1.04-1.23; P=0.003; MPVLR cut-off >6.13) similar to that of PLR a good diagnostic value in predicting long-term mortality (adjusted HR 1.52; 95% CI 1.42-1.63; P<0.0001; MPVLR cut-off >5.88) better than that of PLR. MPVLR remained an independent risk factor of early and late mortality. CONCLUSIONS: To the best of our knowledge, this is the first ever study that has investigated MPVLR. Despite similar clinical characteristics, patients with elevated MPVLR had worse angiographic features which may indicate a greater thrombus burden. Elevated MPVLR is an independent risk factor of early and late mortality following STEMI. In addition, it has similar value to PLR in predicting in-hospital mortality, and a better value than PLR in predicting long-term mortality.
