Monocyte to high-density lipoprotein ratio as a new prognostic marker in patients with STEMI undergoing primary percutaneous coronary intervention

BACKGROUND Monocyte count to high-density lipoprotein ratio (MHR) has recently emerged as an indicator of inflammation and oxidative stress in the literature. We aimed to investigate the prognostic value of MHR in patients with ST-segment elevation myocardial infarction treated with primary percutaneous coronary intervention (PCI). METHODS A total of 513 patients who were hospitalized with diagnosis of acute ST-segment elevation myocardial infarction and treated with primary PCI were retrospectively enrolled in the study. Demographic and clinical data, admission laboratory parameters, and MHR values were recorded. Inhospital major adverse cardiac events (MACE) and mortality were reported as the clinical outcomes. RESULTS Twenty-six patients (5%) died, and MACE was observed in 86 patients (17%) during hospital follow-up. Patients were categorized in 3 groups according to tertiles of admission MHR. The rates of inhospital mortality and MACE were significantly higher in tertile 3 group compared to tertile 1 group (10% vs 1%, 27% vs 11%; P < .01 and P < .01). In multivariate regression analysis, age, sex, presence of Killip 3 or 4, left ventricular ejection fraction, troponin I, C-reactive protein, and increased MHR levels (odds ratio, 1.03; 95% confidence interval, 1.01-1.05; P < .01) independently predicted inhospital mortality; age, presence of Killip 3 or 4, troponin I, and increased MHR levels (odds ratio, 1.02; 95% confidence interval, 1.01-1.04; P < .01) independently predicted MACE. CONCLUSION Admission MHR values were found to be independently correlated with inhospital MACE and mortality after primary PCI.

CHA2DS2-VASc Score is a Predictor of No-Reflow in Patients With ST-Segment Elevation Myocardial Infarction Who Underwent Primary Percutaneous Intervention.

Thrombosis and distal embolization play crucial role in the etiology of no-reflow. CHA2DS2-VASc score is used to estimate the risk of thromboembolism in patients with atrial fibrillation. We tested the hypothesis that CHA2DS2-VASc can predict no-reflow among patients who underwent primary percutaneous coronary intervention (PCI). A total number of 2375 consecutive patients with ST-segment elevation myocardial infarction were assessed for the study. Patients were divided into 2 groups as no-reflow (n = 111) and control (n = 1670) groups according to post-PCI no-reflow status. CHA2DS2-VASc scores were calculated for all patients. CHA2DS2-VASc scores were significantly higher in the no-reflow group compared to the control group. After a multivariate regression analysis, CHA2DS2-VASc score remained as an independent predictor (odds ratio: 1.58, 95% confidence interval: 1.33-1,88, P < .001) of no-reflow. Receiver–operating characteristics analysis revealed the cutoff value of CHA2DS2-VASc score ≥2 as a predictor of no-reflow with a sensitivity of 66% and a specificity of 59%. Moreover, in-hospital mortality was also associated with significantly higher CHA2DS2-VASc scores. In conclusion, CHA2DS2-VASc score is associated with higher risk of no-reflow and in-hospital mortality rates in patients who underwent primary PCI.

The neutrophil-to-lymphocyte ratio is associated with bare-metal stent restenosis in STEMI patients treated with primary PCI.

BackgroundThe clinical importance of complete blood count (CBC) parameters such as the neutrophil-to-lymphocyte ratio (NLR) has been shown in cardiovascular diseases. Stent restenosis (SR) is a major adverse event after stent implantation. In this study, we aimed to investigate the correlation of CBC parameters with SR rates after primary percutaneous coronary intervention (PCI). MethodsPatients who had undergone primary PCI for ST-segment elevation myocardial infarction (STEMI) and control angiography during follow-up were retrospectively recruited. Patients were categorized according to admission NLR tertiles, and clinical, hematological, and angiographic data were compared. ResultsA total of 404 patients (207 patients with SR and 197 patients without SR) were included in the study. Patients were categorized into three groups according to the tertiles of admission NLRs; the NLR was less than 3.38 in tertile 1 (n=134), between 3.38 and 6.26 in tertile 2 (n=135), and greater than 6.26 in tertile 3 (n=135). During a follow-up period of a median of 14 months (minimum 6 months, maximum 60 months) SR developed in 80 patients of tertile 3 (59%), 74 patients of tertile 2 (55%), and 53 patients of tertile 1 (40%), which were significantly different (P=0.01). According to multivariate Cox regression analysis, male sex, stent length (odds ratio 1.04, 95% confidence interval 1.01–1.06, P=0.01), admission NLRs (odds ratio 1.13, 95% confidence interval 1.08–1.19, P=0.01), and white blood cell and neutrophil counts remained the independent predictors of SR in the study population. Other CBC parameters and admission C-reactive protein, creatinine, and fasting glucose levels were not independently correlated with SR. On receiver operating curve analysis, admission NLRs higher than 3.84 were found to predict SR with a sensitivity of 73.4% and a specificity of 50.8% (area under the curve 0.604, P=0.01). ConclusionHigh NLR levels, white blood cell counts, and neutrophil counts at admission are independently correlated with SR after primary PCI.

Association of admission serum laboratory parameters with new-onset atrial fibrillation after a primary percutaneous coronary intervention.

ObjectivesNew-onset atrial fibrillation (NOAF) during hospitalization is considered a frequent complication associated with worse outcomes in the setting of ST-segment elevation myocardial infarction (STEMI). We aimed to investigate the association of admission serum laboratory parameters, neutrophil to lymphocyte ratio (NLR), and monocyte to high-density lipoprotein ratio (MHR) with NOAF in STEMI patients treated with a primary percutaneous coronary intervention (PCI). Patients and methodsA total of 621 patients who were hospitalized with a diagnosis of STEMI and treated with primary PCI were retrospectively enrolled in the study. NOAF during index hospitalization and overall mortality were reported as the clinical outcomes. ResultsIn our study population, 40 (6.4%) patients developed NOAF during index hospitalization. Monocyte counts, mean platelet volume (MPV), red cell distribution width (RDW), NLR, MHR, C-reactive protein (CRP), creatinine, glucose, and uric acid levels were higher in the NOAF+ group compared with the NOAF− group. In multivariate regression analysis, age, left-ventricular ejection fraction, left atrial volumes, admission heart rate, multivessel disease, increased levels of CRP, MPV, RDW, uric acid, NLR, and MHR independently predicted NOAF. In addition, NOAF was found to be an independent predictor of overall mortality in the study population. ConclusionFor the first time in the literature, admission serum levels of MPV, RDW, uric acid, NLR, and MHR were found to be correlated independently with NOAF after primary PCI.

Assessment of Prognostic Value of Neutrophil to Lymphocyte Ratio and Platelet to Lymphocyte Ratio in Patients with Pulmonary Embolism.

BACKGROUND Acute pulmonary embolism is a serious medical condition that has a substantial global impact. Inflammation plays a role in the pathophysiology and prognosis of acute pulmonary embolism (APE). The aim of the present study was to investigate the prognostic value of admission parameters for complete blood count (CBC) in APE. METHODS A total of 203 patients who were hospitalized with diagnosed APE were retrospectively enrolled in the study. Clinical data, PESI scores, admission CBC parameters, neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) were all recorded. The clinical outcomes of study subjects were determined by the reported patient 30-day mortality and long-term mortality. RESULTS During a median follow-up period of 20 months [interquantile range 17], 34 subjects in the study population (17%) died. NLR and PLR levels were significantly higher in patients who died within the 30 days (n = 14) [9.9 (5.5) vs. 4.5 (4.1), p = 0.01 and 280 (74) vs. 135 (75), p = 0.01, respectively] and during the long-term follow-up (n = 20) [8.4 (2.9) vs. 4.1 (3.8), p = 0.01 and 153 (117) vs. 133 (73), p = 0.03, respectively] when compared to the patients that survived. In Cox regression analysis, age, systolic blood pressure, systolic pulmonary arterial pressure, PESI scores (HR 1.02 95%CI 1.01-1.04, p = 0.01), elevated levels of NLR (HR 1.13 95%CI 1.04-1.23, p = 0.01) and PLR (HR 1.002 95%CI 1.001-1.004, p = 0.01) were independently correlated with total mortality. CONCLUSIONS Admission NLR and PLR may have prognostic value in patients with APE.

Association of Serum Cholesterol Levels with Short-term Mortality in Patients with Acute Pulmonary Embolism

BACKGROUND Serum cholesterols play an important role in pathophysiology and prognosis of acute thrombotic diseases. The aim of the present study was to investigate the prognostic value of serum lipid parameters in acute pulmonary embolism (APE). METHODS From January 2008 to January 2014 a total of 275 patients who were hospitalised with a diagnosis of APE were retrospectively screened. Clinical data, laboratory parameters, serum cholesterol levels were recorded and pulmonary embolism severity index (PESI) scores were calculated. Mortality rate at 30 days was investigated as the clinical outcome. RESULTS In our study population, 24 patients (8.7%) died within 30 days. Serum total cholesterol, LDL-C, HDL-C and triglyceride levels were significantly lower in deceased patients when compared to the survived patients (3.1 ± 0.6 vs. 4.7 ± 1.2 mmol/L, p < 0.01; 1.8 ± 0.9 vs. 2.9 ± 0.9 mmol/L, p < 0.01; 0.9 ± 0.3 vs. 1.2 ± 0.3 mmol/L, p < 0.01; 1.4 ± 0.7 vs. 1.7 ± 0.6 mmol/L, p = 0.04, respectively). In multivariate regression analysis; PESI scores (OR: 1.06 95% CI: 1.01-1.11, p < 0.01), right ventricular diameter (OR: 11.31 95% CI: 3.25-52.64, p < 0.01), total cholesterol (OR: 1.09 95% CI: 1.02-1.17, p < 0.01), LDL-C (OR: 1.06 95% CI: 1.01-1.12, p = 0.02), HDL-C (OR: 1.21 95% CI: 1.04-1.41, p < 0.01) and triglyceride (OR: 1.03 95% CI: 1.01-1.05, p < 0.01) levels were independently correlated with mortality. CONCLUSIONS Serum total cholesterol, LDL-C, HDL-C and triglyceride levels, obtained within the first 24hours of hospital admission, may have prognostic value in patients with APE.

Relationship between Neutrophil-to-Lymphocyte Ratio and Left Ventricular Free Wall Rupture in Acute Myocardial Infarction

Objectives: This study aimed to evaluate the relationship between the neutrophil-to-lymphocyte (N/L) ratio and left ventricular free wall rupture (LVFWR) in patients with ST elevation myocardial infarction (STEMI). Previous studies showed a correlation between increased levels of inflammatory markers and adverse cardiovascular events. The role of inflammation markers, particularly the N/L ratio, in mechanical complications after myocardial infarction has not been studied. Methods: Retrospectively, we compared the N/L ratio values of 23 patients with STEMI complicated by LVFWR with 214 STEMI patients without this complication. The diagnosis of rupture was confirmed by echocardiography in each case. Results: Neutrophil counts [median 8.5 × 103/µl, interquartile range (IQR) 6.4, vs. 7.8 × 103/µl, IQR 4.7, p = 0.02] and the N/L ratio (5.66, IQR 4.17, vs. 4.1, IQR 3.93, p = 0.01) were significantly higher in the LVFWR group. In receiver operating characteristic analysis, an N/L ratio above 3.7 predicted LVFWR with a sensitivity of 82.6% and a specificity of 46.9% (area under the curve = 0.654, p = 0.016). In multivariate regression analysis, age, hypertension, increased creatinine levels and increased N/L ratio (odds ratio = 1.61, 95% confidence interval = 1.15-2.23, p = 0.01) were found to be independent predictors of LVFWR. Conclusions: In our study, the N/L ratio was found to be independently correlated with the risk of LVFWR.

Anxiety, Depression, and General Psychological Distress in Patients with Coronary Slow Flow.

Background The relationship between psychiatric illness and heart disease has been frequently discussed in the literature. The aim of the present study was to investigate the relationship between anxiety, depression and overall psychological distress, and coronary slow flow (CSF). Methods In total, 44 patients with CSF and a control group of 50 patients with normal coronary arteries (NCA) were prospectively recruited. Clinical data, admission laboratory parameters, and echocardiographic and angiographic characteristics were recorded. Symptom Checklist 90 Revised (SCL-90-R), Beck Depression Inventory (BDI), and Beck Anxiety Inventory (BAI) scales were administered to each patient. Results The groups were comparable with respect to age, sex, and atherosclerotic risk factors. In the CSF group, BAI score, BDI score, and general symptom index were significantly higher than controls (13 [18.7] vs. 7.5 [7], p = 0.01; 11 [14.7] vs. 6.5 [7], p = 0.01; 1.76 [0.81] vs. 1.1[0.24], p = 0.01; respectively). Patients with CSF in more than one vessel had the highest test scores. In univariate correlation analysis, mean thrombolysis in myocardial infarction (TIMI) frame counts were positively correlated with BAI (r = 0.56, p = 0.01), BDI (r = 0.47, p = 0.01), and general symptom index (r = 0.65, p = 0.01). The psychiatric tests were not correlated with risk factors for atherosclerosis. Conclusion Our study revealed higher rates of depression, anxiety, and overall psychological distress in patients with CSF. This conclusion warrants further studies.
