The Effect of Computerized Wobble Board and Core Stabilization Exercises on Balance Performance and Exercise Capacity in Patients With Heart Failure: A Randomized Controlled Trial.

OBJECTIVE: To investigate the effects of computerized wobble board exercise training (CWBET) and core stabilization exercise training (CSET) on balance performance, and exercise capacity in patients with heart failure (HF). DESING: Single-blind randomized controlled prospective study. SETTING: Cardiology department of a local university hospital. PARTICIPANTS: Fifty-one patients with HF with reduced ejection fraction, whose clinical status and medication had been stable for the previous 3 months, were included (N=51). Nine patients could not complete the follow-up period due to personal reasons. No patient experienced any adverse events during exercise training. INTERVENTIONS: Patients were randomized to CWBET, CSET, and control group. CWBET and CSET groups participated in their own exercise programs, 3 days a week for 8 weeks. The control group received no exercise program. MAIN OUTCOME MEASURES: All patients were evaluated at baseline and after 8 weeks. Postural stability, static and functional balance, and exercise capacity were evaluated with the Sensamove Balance Test Pro with Miniboard, the one-leg stance test (OLS), the Berg Balance Scale (BBS), and the six-minute walk distance (6MWD), respectively. Core stabilization and health-related quality of life (HRQOL) were assessed with OCTOcore app, and Minnesota Living with Heart Failure Questionnaire, respectively. RESULTS: A mixed model repeated-measures ANOVA revealed significant group × time interaction effect for static postural stability performance (P<.001, ηp2=0.472), vertical (P<.001, ηp2=0.513), horizontal performance (P<.001, ηp2=0.467), OLS (P<.001, ηp2=0.474), BBS (P<.001, ηp2=0.440) scores, 6MWD (P<.001, ηp2=0.706), and HRQOL. Post hoc analysis revealed CWBET and CSET groups had similar improvements balance performance, exercise capacity, and HRQOL and both groups significantly improved compared with control group (P<.001). Core stabilization was significantly improved only in CSET group after 8 weeks. CONCLUSION: CWBET and CSET programs were equally effective and safe for improving balance performance and exercise capacity in patients with HF.

The association between ABO blood groups and TASC II classification in patients with peripheral artery disease.

OBJECTIVE: The aim of this study was to investigate the association between blood groups and severity of peripheral artery disease (PAD) using TASC II classification. METHODS: The patients who were diagnosed with PAD were retrospectively analyzed. The patients with 50% or more stenosis in the aorto-iliac or femoro-popliteal region detected by conventional or CT angiography were included in the study. These patients were divided into TASC II A, B, C, and D groups considering the severity of PAD. All patients' blood groups were recorded and compared between TASC II groups. RESULTS: While 38% of the study population was O blood group, 61% were non-O group. On the other hand, 90% of the entire study population were RH positive and 10% were RH negative. Non-O blood ratio was found to be significantly higher in patients with higher TASC II groups. (TASC IIA 51.6% vs. TASC IIB 57.9% vs. TASC IIC 61.3% vs. TASC IID 76.6%, p< .001) However, the frequencies of Rh types were similar in all groups. Multiple logistic regression analysis was applied for determining the predictors of severity and complexity of PAD (TASC II C and TASC II D lesions). CONCLUSIONS: Our study results revealed a clear association between ABO blood groups and severity of peripheral arterial disease. Non-O blood group was found to be the independent predictor of severe and complex PAD.

A New Insight Into Pathophysiological Mechanism of Abdominal Aortic Aneurysm With Novel Parameters Salusin-ß and Arterial Stiffness.

BACKGROUND: Abdominal aortic aneurysm (AAA) has risk factors similar to those of atherosclerosis. Salusin-ß and arterial stiffness are novel parameters that have been shown to predict atherosclerosis and related cardiovascular disorders. However, their predictive value for detecting AAA remains unclear. METHODS: Forty-eight patients with AAA and 47 age- and sex-matched participants without AAA were enrolled in the study. Arterial stiffness parameters were obtained via an oscillometric Mobil-O-Graph PWA Monitor device (IEM GmbH) with integrated ARCSolver software (Australian Institute of Technology). Plasma salusin-ß levels were analyzed using an enzyme-linked immunosorbent assay reagent kit (Abbkine, Inc). The measured salusin-ß levels and arterial stiffness parameters of the AAA and control groups were compared. RESULTS: Salusin-ß levels were significantly lower in patients with AAA (P = .014). There was a significant negative correlation between salusin-ß levels and abdominal aorta diameter. No significant difference was detected between AAA and control groups in terms of arterial stiffness parameters (P > .05). In backward multiple regression analysis, the presence of AAA, platelet count, and augmentation index were found to be independent predictors of salusin-ß levels (P = .006 and P = .023, respectively). CONCLUSION: Arterial stiffness parameters were not found to be associated with AAA. Contrary to previous results regarding atherosclerosis and related cardiovascular disorders, salusin-ß levels were found to be lower in patients with AAA. Although AAA is thought to have similar risk factors as atherosclerosis, the exact pathophysiologic mechanism remains unclear.

Well-Developed Coronary Collateral Circulation Is Associated With Higher Thrombus Burden in the Setting of ST-Segment Elevation Myocardial Infarction.

BACKGROUND: This study investigated the relationship between coronary collateral circulation (CCC) and intracoronary thrombus burden in patients undergoing primary percutaneous coronary intervention for ST-segment elevation myocardial infarction (STEMI). CCC and thrombus burden are predictive of clinical outcomes in patients with STEMI. METHODS: Patients with STEMI undergoing primary percutaneous coronary intervention were enrolled (n = 172). CCC was graded according to the Cohen-Rentrop classification. Patients were classified as insufficient (grade 0 or 1, n = 134) or well-developed (grade 2 or 3; n = 38) CCC. The Thrombolysis in Myocardial Infarction scale was used to evaluate intra-coronary thrombus burden. The low-thrombus-burden group comprised those with grades 0 to 2, and the high-thrombus-burden group comprised those with grades 3 or 4. RESULTS: Right coronary artery infarcts had a 13.830-fold higher chance of having well-developed CCC than did left anterior descending artery infarcts (P < .001). Circumflex artery infarcts had a 7.904-fold higher chance of well-developed CCC than did left anterior descending artery infarcts (P = .016). High thrombus burden was associated with a 4.393-fold higher chance for well-developed CCC than was low thrombus burden (P = .030). Low albumin levels were related to a greater chance of having well-developed CCC (P = .046). CONCLUSION: Patients with well-developed CCC have higher thrombus burden than do those with insufficient CCC. Because well-developed CCC is an indicator of more severe underlying lesions, we speculate that patients with severe lesions are more prone to experience more complicated STEMI with high thrombus burden.

Triphasic mitral flow pattern may indicate subclinical left ventricular systolic dysfunction.

PURPOSE: In this study, the presence and severity of left ventricular (LV) systolic dysfunction were investigated by speckle tracking echocardiography (STE) technique in patients with mitral triphasic mitral flow pattern (TMFP). The aim of the study was to evaluate the possible role of TMFP in the ethiopathogenesis of congestive heart failure. METHODS AND RESULTS: A total of 45 patients who were diagnosed with TMFP and 30 age- and gender-matched healthy volunteers were included in the study. The mean age in the study and control groups was 64 ± 12 and 62 ± 11 (P = .642), respectively. When echocardiographic parameters were evaluated, LV ejection fraction was found to be 63% ± 14 and 64 ± 12 (P = .745), in the study and control groups, respectively. LV end-diastolic and systolic diameters and LV mass index were also similar (P < .05). When LV diastolic parameters were compared, diastolic dysfunction was detected in 38 (84.4%) patients in the study population and 13 patients (43.3%) in the control group (P < .001). When STE findings were evaluated, both global longitidunal strain and global circumferential strain were significantly lower in the TMFP group when compared to controls (18.3 ± 1.7 vs 21.5 ± 1.5, P < .001 and 17.9 ± 1.6 vs 21.3 ± 2.1, P < .001, respectively). CONCLUSION: TMFP results in LV systolic dysfunction. Therefore, these patients may develop congestive heart failure in the long term. It will be rational that the patients with TMFP should be followed up more closely in terms of preventing manifest heart failure symptoms.

The prognostic value of altitude in patients with heart failure with reduced ejection fraction.

OBJECTIVE: It is well known that the altitude may affect the cardiovascular system. However, there were a few data related to the effect of altitude on the adverse outcome in patients with heart failure with reduced ejection fraction (HFREF). The aim of the present study was to investigate the role of intermediate high altitude on the major adverse cardiovascular outcome in patients with HFREF. METHODS: Patients with HFREF admitted to the outpatient clinics at the first center at sea level and the second center at 1890 m were prospectively enrolled in the study. HFREF was defined as symptoms/signs of heart failure and left ventricular ejection fraction <40%. The major adverse cardiac outcome (MACE) was defined as all-cause death, stroke, and re-hospitalization due to heart failure. The median follow-up period of the study population was 27 months. RESULTS: The study included 320 (58.55% male, mean age 65.7±11.2 years) patients. The incidence of all-cause death was 8.5%, stroke 6.1%, re-hospitalization due to decompensated heart failure 34.3%, and MACE 48.9%. In Kaplan-Meier analysis, patients with HFREF living at high altitude had more MACE (71.1% vs. 25.3%, log rank p=0.005) and presented with more stroke (11.3% vs. 2.1%, log rank p=0.001) and re-hospitalization due to heart failure (65.1% vs. 20.1%, log rank p<0.001) rates than those at low altitude in the follow-up; however, the rate of all-cause death was similar (9.4% vs. 8.1%, log rank p=0.245). CONCLUSION: In the present study, we demonstrated that the intermediate high altitude is the independent predictor of MACE in patients with HFREF. High altitude may be considered as a risk factor in decompensating heart failure.

Association between fragmented QRS complexes and left ventricular dysfunction in healthy smokers.

OBJECTIVE: Smoking is a known risk factor for cardiovascular diseases and may cause myocardial damage independently of coronary artery disease. Fragmented QRS (fQRS) is an important marker of myocardial fibrosis, while speckle-tracking echocardiography is a method used to show subclinical left ventricle dysfunction. METHODS: Our study included 230 healthy individuals aged 18-40 years. The patients included were separated into two groups: those smokers (n = 130) and non-smokers (n = 100). After that healthy smokers group were divided into two groups: those with fQRS (n = 24) and those without (n = 106). In both groups, the arithmetic mean of three images was used to obtain the left ventricle global longitudinal strain (LV-GLS). The E/SRe ratio was also calculated and analyzed. RESULTS: There were significant differences between the smokers and non-smokers in terms of, E/SRe (55.7 ± 17.9 vs 50.3 ± 14.8; P = 0.015), LV-GLS (23.1 ± 1.9 vs 24.0 ± 1.7; P = 0.001), and fQRS (18.5% vs 6%; P = 0.005). As a result of subgroup analysis, pack-year history was higher in the fQRS positive group (16.7 ± 3.7 vs 11.2 ± 3.7, P < 0.001). While a negative correlation was observed between pack-year history and LV-GLS (r = -0.678, P < 0.001), there was a positive correlation between pack-year history and E/SRe (r = 0.730, P < 0.001). CONCLUSION: In conclusion, our study demonstrated that fQRS is a parameter that can be used to determine left ventricle subclinical systolic and diastolic dysfunction in smokers, and that left ventricle dysfunction is related to the duration and intensity of smoking.

The presence of fragmented QRS is associated with increased epicardial adipose tissue and subclinical myocardial dysfunction in healthy individuals.

AIM: The aim of this study was to measure epicardial adipose tissue (EAT) and to assess left ventricular (LV) systolic and diastolic function in a healthy population grouped according to the presence of fragmented QRS (fQRS). METHODS: In this prospective case-control study, the study population consisted of 308 healthy individuals who were divided into two groups according to the existence of fQRS: 180 fQRS(+) individuals (with fQRS), and 128 age- and gender-matched fQRS(-) individuals (without fQRS). These individuals were assessed for EAT thickness and subclinical myocardial dysfunction using transthoracic echocardiography including strain imaging. RESULTS: The baseline clinical characteristics were similar between groups. EAT thickness was significantly increased in fQRS(+) individuals (0.59 vs. 0.44 mm, p<0.001). LV global longitudinal strain, reflecting systolic function (19.62±3.05 vs. 20.95±2.36, p<0.001) and E/A ratio, reflecting diastolic function (0.95±0.30 vs. 1.10±0.37, p<0.001), were decreased, revealing subclinical myocardial dysfunction, in fQRS(+) individuals. CONCLUSIONS: The presence of fQRS on the admission ECG is associated with increased EAT and pronounced subclinical LV systolic and diastolic dysfunction in a healthy population. Further studies with larger patient groups are needed to clarify the exact pathophysiological mechanisms underlying these findings in healthy populations.

Usefulness of admission red blood cell distribution width as a predictor of severity of acute pulmonary embolism.

BACKGROUND: Previous researches have represented a considerable relation between acute pulmonary embolism (PE) and red blood cell distribution width (RDW). To the authors' knowledge no research has been informed in subjects with PE severity. Pulmonary arterial obstruction index (PAOI) is associated with the severity of acute PE. OBJECTIVES: In our investigation, we purposed to assess the relation between PAOI and RDW and the benefit of these factors in the detection of PE severity. METHODS: We retrospectively investigated the demographic information, probability of clinical scores, laboratory parameters, serum D-dimer levels, and echocardiographic findings of systolic pulmonary artery pressure (PAP) in Acute PE individuals who were diagnosed by computed tomography of pulmonary arterial angiography. Right ventricular dysfunction (RVD) on CT was assessed by calculating the right ventricular/left ventricular (RV/LV) diameter ratios on transverse (RV/LVtrans). RESULTS: The information of 131 patients with acute PE and 51 (64.6%) female and 28 (35.4%) male healthy control were evaluated. Acute PE group's RDW values were higher than control subjects (P < .0001). RDW (%) level was remarkable higher in patients with massive PE than in patients with nonmassive PE. There were statistically considerable differences in terms of PAOI and systolic pulmonary arterial pressure (sPAP) between nonmassive and massive PE patients (P < .0001 for all). CONCLUSIONS: PAOI was correlated with PE severity, D-dimer level, sPAP and clinical probability scores. PAOI was correlated with RDW levels. RDW levels, an inexpensive and easily measurable laboratory factor, were considerable associated with the severity and presence of PE.

Prediction of no-reflow and major adverse cardiovascular events with a new scoring system in STEMI patients.

BACKGROUND: No-reflow is associated with a poor prognosis in STEMI patients. There are many factors and mechanisms that contribute to the development of no-reflow, including age, reperfusion time, a high thrombus burden, Killip class, long stent use, ejection fraction ≤40, and a high Syntax score. In this study, we aimed to evaluate the parameters associated with no-reflow prediction by creating a new scoring system. METHODS: The study included 515 consecutive STEMI patients who underwent PCI; 632 STEMI patients who had undergone PCI in another center were included in the external validation of the scoring system. The correlations between 1-year major adverse cardiac events and low/high risk score were assessed. RESULTS: In this study, seven independent variables were used to build a risk score for predicting no-reflow. The predictors of no-reflow are age, EF ≤40, SS ≥22, stent length ≥20, thrombus grade ≥4, Killip class ≥3, and pain-balloon time ≥4 h. In the derivation group, the optimal threshold score for predicting no-reflow was >10, with a 75% sensitivity and 77.7% specificity (Area under the curve (AUC) = 0.809, 95%CI: 0.772-0.842, P < 0.001). In the validation group, AUC was 0.793 (95%CI: 0.760-0.824, P < 0.001). CONCLUSION: This new score, which can be calculated in STEMI patients before PCI and used to predict no-reflow in STEMI patients, may help physicians to estimate the development of no-reflow in the pre-PCI period.

Fragmented QRS complexes are associated with left ventricular dysfunction in patients with type-2 diabetes mellitus: a two-dimensional speckle tracking echocardiography study.

Background: Heart failure may develop independently of coronary artery disease in diabetes mellitus (DM) patients. Fragmented QRS (fQRS) is a marker of myocardial fibrosis or scar tissue and is related to an increase in cardiovascular adverse events. In this study, we examined the utility of speckle tracking echocardiography (STE) in assessing LV function in DM patients with fQRS. Methods and Results: The current study included 178 consecutive patients diagnosed with type-2 DM. The patients included were separated into two groups: those with (n = 50) and without (n = 128) fQRS. The two groups were compared by obtaining LV strain values with STE. Statistically significant differences were also identified between fQRS(-) and fQRS (+) groups with respect to Lv-GLS (p < .001), maxLAVI (p = .020), minLAVI (p < .001), E velocity (p < .001), Em velocity (0.002), E/Em ratio (<0.001) SRe (p < .001), SRe/SRa ratio (p < .001), SRivr (p < .001) and E/SRivr ratio (p < .001). In the multiple linear regression analysis, fQRS (ß = -2.077, p = .002) and DM duration (ß = -0.216, p = .021) were identified as independent predictors of Lv-GLS. However, fQRS (ß = 4.557, p = .001) and minLAVI (ß = -2.198, p = .031) were also found to be independent predictors of E/SRivr. We also performed multiple logistic regression analysis and identified Lv-GLS (ß = -0.557, p = .001), minLAVI (ß = -0.769, p = .001), E/Em ratio (ß = 0.650, p = .001) and E/SRivr (ß = 0.105, p = .001) as independent predictors of fQRS. Conclusions: The results of this study revealed that subclinical LV dysfunction was more common in diabetic patients with fQRS. Therefore, determination of fQRS could be an indicator of the diabetic CMP in patients with DM.

The effects of treatment in patients with childhood asthma on the elastic properties of the aorta.

INTRODUCTION: The study aimed to investigate the effects of treatment in patients with childhood asthma on the elastic properties of the aorta and cardiovascular risk. METHODS: The study was performed in 66 paediatric patients diagnosed with bronchial asthma (BA). All patients were administered the ß2 agonist, salbutamol, for seven days, followed by one month of montelukast and six months of inhaled steroid treatment. All patients underwent conventional transthoracic echocardiographic imaging before and after treatment. Aortic elasticity parameters were considered to be the markers of aortic function. RESULTS: Aortic elasticity parameters, including aortic strain (15.2 ± 4.8 and 18.8 ± 9.5%, p = 0.043), aortic distensibility (7.26 ± 4.71 and 9.53 ± 3.50 cm2/dyn, p = 0.010) and aortic stiffness index (3.2 ± 0.6 and 2.8 ± 0.5, p = 0.045 showed significant post-treatment improvement when compared to pre-treatment values. Tricuspid annular plane systolic excursion (TAPSE) was also observed to improve after treatment (1.81 ± 0.38 and 1.98 ± 0.43, p = 0.049). CONCLUSION: The study demonstrated that when provided at appropriate doses, medications used in BA may result in an improvement in aortic stiffness.

Effects of levodopa therapy on global left ventricular systolic function in patients with Parkinson disease.

OBJECTIVES: Since levodopa was identified as an efficient therapeutic option in Parkinson disease (PD), great success has been achieved in the course and treatment of the disease. However, L­dopa-related side effects limit the therapeutic use in some patients. The aim of this study was to evaluate the effects of L­dopa therapy on left ventricular global systolic function via speckle tracking method. METHODS: In this study, 55 patients with PD under L­dopa/dopa decarboxylase inhibitor therapy were compared with 30 age- and sex-matched control subjects. Conventional transthoracic echocardiography was performed in the left lateral position by two experienced operators in accordance with generally accepted guidelines. Left ventricular systolic function was analyzed by speckle tracking method using global longitudinal strain (GLS) and global circumferential strain (GCS) imaging. RESULTS: Adequate echocardiographic imaging for the evaluation of global longitudinal strain and global circumferential strain could be achieved in 55 of the patients. LVEF (left ventricular ejection fraction), GLS and GCS values were found to be similar between the patients with PD under L­dopa therapy and the control group (62 ± 3.5 % vs 61 ± 4 %, p < 0.05; -19.46 ± 2.3 vs -19.4 ± 3.2, p < 0.05; and -18.60 ± 3.5 vs -18.22 ± 3.2, p < 0.05 respectively.) CONCLUSION: Levodopa therapy has no unfavorable effect on left ventricular systolic function in patients with PD.

Stenting of Variant Left Carotid Artery Using Brachial Artery Approach in a Patient with Unusual Type of Bovine Aortic Arch.

Bovine aortic arch is the most frequently encountered variation in human aortic arch branching. A 63-year-old Asian male presented with symptomatic severe stenosis of left carotid artery originating from the brachiocephalic trunk. Selective engagement to the left carotid artery was unsuccessful using transfemoral approach. We reported on a successful left carotid artery stenting case using right brachial artery approach in a bovine aortic arch. This paper is worthy of reporting in terms of guiding physicians for interventional procedures in these types of challenging cases.

Evaluation of cardiovascular risk in patients with Parkinson disease under levodopa treatment.

BACKGROUND: Levodopa is the indispensable choice of medial therapy in patients with Parkinson disease (PD). Since L-dopa treatment was shown to increase serum homocysteine levels, a well-known risk factor for cardiovascular disorders, the patients with PD under L-dopa treatment will be at increased risk for future cardiovascular events. The objective of this study is to evaluate cardiovascular risk in patients with PD under levodopa treatment. METHODS: The study population consisted of 65 patients with idiopathic PD under L-dopa treatment. The control group included 32 age and gender matched individuals who had no cognitive decline. Echocardiographic measurements, serum homocysteine levels and elastic parameters of the aorta were compared between the patients with PD and controls. RESULTS: As an expected feature of L-dopa therapy, the Parkinson group had significantly higher homocystein levels (15.1 ± 3.9 µmol/L vs. 11.5 ± 3.2 µmol/L, P = 0.02). Aortic distensibility was significantly lower in the patients with PD when compared to controls (4.8 ± 1.5 dyn/cm(2) vs. 6.2 ± 1.9 dyn/cm(2), P = 0.016). Additionally, the patients with PD had higher aortic strain and aortic stiffness index (13.4% ± 6.4% vs. 7.4% ± 3.6%, P < 0.001 and 7.3 ± 1.5 vs. 4.9 ± 1.9, P < 0.001 respectively). Furthermore, serum homocysteine levels were found to be positively correlated with aortic stiffness index and there was a negative correlation between aortic distensibility and levels of serum homocysteine (r = 0.674, P < 0.001; r = -0.602, P < 0.001, respectively). CONCLUSIONS: The patients with PD under L-dopa treatment have increased aortic stiffness and impaired diastolic function compared to healthy individuals. Elevated serum homocysteine levels may be a possible pathophysiological mechanism.

The preventive role of the posterior pericardial window in the development of late cardiac tamponade following heart valve surgery.

OBJECTIVES: It is reported that creating a window from the posterior pericardium into the left pleural cavity during coronary bypass surgeries reduces postoperative late cardiac tamponades. Although late tamponades are more common after heart valve surgeries, this procedure is not generally performed. The present study investigated whether creating a window has a preventive effect on the formation of late cardiac tamponade after heart valve surgeries. METHODS: The study was conducted on all patients (n = 262) in whom one or more valves were replaced and who fulfilled the study criteria between January 2010 and October 2014 in one centre. We began to create a posterior pericardial window in all valvular patients from March 2012. One hundred and thirty-five patients operated on before this date (Non-Window Group) and 127 patients after this date (Window Group) were compared for the development of late cardiac tamponade. RESULTS: There were no differences between the groups in terms of preoperative and intraoperative characteristics. Late pericardial tamponade was not observed in any patients from the Window Group, whereas it occurred in 7 (5.2%) patients from the Non-Window Group (P = 0.015). Three patients died in total; all 3 were from the Non-Window Group. One of the mortalities was associated with tamponade. CONCLUSIONS: Creating a pericardial window may reduce late cardiac tamponade events/episodes, which may be a fatal complication in valve patients. We recommend performing this procedure by allocating some time during the surgical procedure in order to avoid tamponade.

The Prognostic Impact of In-Hospital Change in Mean Platelet Volume in Patients With Non-ST-Segment Elevation Myocardial Infarction.

It is unclear whether changes in mean platelet volume (MPV) are associated with total mortality in acute coronary syndromes. We investigated whether the change in MPV predicts total mortality in patients with non-ST-segment elevation myocardial infarction (NSTEMI). We retrospectively analyzed 419 consecutive patients (19 patients were excluded). The remaining patients were categorized as survivors (n = 351) or nonsurvivors (n = 49). Measurements of MPV were performed at admission and after 24 hours. The difference between the 2 measurements was considered as the MPV change (ΔMPV). The end point of the study was total mortality at 1-year follow-up. During the follow-up, there were 49 deaths (12.2%). Admission MPV was comparable in the 2 groups. However, both MPV (9.6 ± 1.4 fL vs 9.2 ± 1.0 fL, P = .044) and ΔMPV (0.40 [0.10-0.70] fL vs 0.70 [0.40-1.20] fL, P < .001) at the first 24 hours were higher in nonsurvivors than survivors. In multivariate analysis, ΔMPV was an independent predictor of total mortality (odds ratio: 1.84, 95% confidence interval: 1.28-2.65, P = .001). An early increase in MPV after admission was independently associated with total mortality in patients with NSTEMI. Such patients may need more effective antiplatelet therapy.

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.
