Heart Rate Recovery Is Impaired in Patients with Inflammatory Bowel Diseases.

OBJECTIVE: In this study we aimed to investigate heart rate recovery (HRR) in patients with inflammatory bowel disease (IBD). SUBJECTS AND METHODS: A total of 40 patients with IBD and 30 healthy controls were included in this study. A treadmill stress test was performed in all the patients to calculate the HRR index based on the age-specific maximum heart rate. The HRR indices were calculated as follows: HRR1, 2, 3, 4, 5 = heart rate at peak exercise - heart rate at 1, 2, 3, 4, and 5 min. The independent samples t test was used to compare HRR indices between the patient and control groups. The Pearson correlation coefficient was used to examine the association between the duration of IBD and the HRR indices. Multivariate regression analysis was carried out to identify predictors of impaired HRR in patients with IBD. RESULTS: HRR indices at various time intervals were significantly lower in the patients with IBD than in the controls: HRR1 (1.18 ± 8 vs. 31 ± 7, p < 0.001), HRR2 (36 ± 12 vs. 51 ± 8, p < 0.001), HRR3 (46 ± 12 vs. 62 ± 11, p < 0.001), HRR4 (54 ± 7 vs. 65 ± 8, p < 0.001), and HRR5 (55 ± 13 vs. 71 ± 15, p < 0.001). Mean duration of IBD was 7.8 ± 3.6 years. In addition, there was a significant negative correlation between disease duration and HRR at the first minute (r = -0.704, p < 0.001). Multivariate logistic regression analysis showed that symptom duration (OR: 1.742, 95% CI: 1.148-2.636, p = 0.009) was an independent predictor of impaired HRR in patients with IBD. CONCLUSION: In this study, the data showed that the HRR was impaired in patients with IBDs. Hence, given the prognostic value of the test, patients with IBD should be monitored for future cardiovascular events.

Association of Left Atrial Spontaneous Echo Contrast to Uric Acid in Patients with Mitral Stenosis.

OBJECTIVES: Spontaneous echo contrast (SEC) is the presence of smoke-like echoes with a characteristic swirling motion of the blood in echocardiography. Previous clinical studies have shown that SEC is a risk factor for left atrial thrombus formation and a predictor of potential systemic embolism originating from the heart. There is an association between uric acid and prothrombotic state. Therefore, we aimed to investigate the role of uric acid in SEC in patients with mitral stenosis (MS). METHODS: A total of 85 consecutive patients with MS were enrolled in the study. Patients were divided into two groups according to whether SEC was present in the left atrium. RESULTS: There were 41 patients (mean age 46.4 ± 11.4 and 68% female) in the SEC(-) group and 44 patients (mean age 45.7 ± 7.2 and 64% female) in the SEC(+) group. High sensitive C-reactive protein (hs-CRP) levels were significantly higher in the SEC(+) group than in the SEC(-) group (9.5 ± 4.2 vs. 4.7 ± 2.2 mg/L, P < 0.001). Uric acid was also significantly higher in the SEC (+) group (6.3 ± 1.4 vs. 4.5 ± 1.3 mg/dL, P < 0.001). In receiver operating characteristics curve analysis, uric acid >5.2 mg/dL had a 73% sensitivity and 76% specificity in predicting SEC in patients with MS. At multivariate analysis, uric acid (OR 3.919, 95% CI 1.911-8.035; P < 0.002) was an independent risk factor for SEC in patients with MS. CONCLUSION: Uric acid is independently associated with SEC in patients with MS. Our findings suggest that this inexpensive, universally available marker may be a useful biomarker for the stratification of risk in patients with MS.

Neutrophil to lymphocyte ratio predicts SYNTAX score in patients with non-ST segment elevation myocardial infarction.

In this study we aimed to investigate whether there is an association between the neutrophil to lymphocyte ratio (NLR) and severity of coronary artery disease (CAD) in patients with non-ST segment elevation myocardial infarction (NSTEMI) using the SYNTAX score (SXscore). A total of 414 patients with NSTEMI who underwent coronary angiography were enrolled in the study. NLR was measured for all patients at presentation. The study population was then divided into 3 tertiles based on the SYNTAX trial results.(1)) The low syntax group (n = 329) was defined as those with an SXscore ≤ 22, the intermediate syntax group (n = 58) was defined as an SXscore ≥ 23 and < 33, and the high syntax group (n = 27) as those with an SXscore ≥ 33. NLR was significantly lower in patients with a low SXscore compared to patients with an intermediate SXscore or high SXscore (3.7 ± 4 to 4.6 ± 2 and 7.9 ± 4, P < 0.001). Linear regression analysis revealed that NLR (coefficientß = 0.380, 95%CI: 1.165-1.917, P < 0.001) was significantly associated with the SXscore in patients with NSTEMI. Our results indicate that NLR is independently associated with the severity of CAD in patients with NSTEMI.

Association of red blood cell distribution width levels with severity of coronary artery disease in patients with non-ST elevation myocardial infarction.

OBJECTIVES: The aim of this study was to evaluate the association of the levels of red blood cell distribution width (RDW) with the severity of atherosclerosis and to determine whether or not the RDW level on admission is an independent predictor of all-cause mortality in patients with non-ST elevation myocardial infarction (NSTEMI). MATERIALS AND METHODS: A total of 335 consecutive patients with NSTEMI were enrolled in this study. The patients were divided into high (n = 105) and low (n = 230) SYNTAX groups. The high SYNTAX group was defined as patients with a value in the third tertile (SYNTAX score, SXscore ≥12), while the low SYNTAX group was defined as those with a value in the lower 2 tertiles (SXscore <12). The high RDW group (n = 152) was defined as patients with RDW >14.25% and the low RDW group (n = 183) as those with RDW ≤14.25%. All-cause mortality was followed up to 38 months. RESULTS: The mean follow-up period was 18 ± 11 months. The RDW levels of patients were significantly higher in the high SYNTAX group than in the low SYNTAX group (15.2 ± 1.8 vs. 14.2 ± 1.2, p < 0.001). Pearson's coefficients were used to determine the degree of association between RDW levels and SXscore and also between RDW levels and high-sensitivity C-reactive protein. There was a significant correlation between RDW levels and SXscore (r = 0.460, p < 0.001). Also, there was a significant correlation between RDW levels and high-sensitivity C-reactive protein (r = 0.180, p = 0.001). All-cause mortality rate was not significantly different between the high and low RDW groups (log-rank, p = 0.621). CONCLUSION: RDW levels were independently associated with high SXscore but were not associated with long-term mortality in NSTEMI patients.

Heart rate recovery is impaired in patients with psoriasis.

OBJECTIVE: The aim of this study was to investigate the relationship between psoriasis and heart rate recovery (HRR) index. PATIENTS AND METHODS: A total of 50 patients with a diagnosis of psoriasis and 32 healthy volunteers were included in the study. In all patients, a stress test was performed to calculate the HRR index in a manner which aimed to reach the age-specific maximum heart rate. HRR indices were calculated in all patients and controls. RESULTS: HRR (beats/minute) indices after the 1st (HRR1, 26 ± 10 vs. 33 ± 8, p = 0.002), 2nd (44 ± 11 vs. 50 ± 6, p = 0.002), 3rd (51 ± 7 vs. 63 ± 8, p < 0.001), 4th (54 ± 7 vs. 65 ± 8, p < 0.001) and 5th (57 ± 8 vs. 70 ± 10, p < 0.001) minutes of the recovery period were significantly lower in the psoriasis group compared to healthy controls. In addition, HRR1 was significantly correlated with duration of psoriasis (r = 0.541, p < 0.001) and psoriasis area and severity index score (r = 0.511, p < 0.001). CONCLUSION: HRR was lower in patients with psoriasis. Given the prognostic value of this test, patients with psoriasis might be at risk for future cardiovascular events and cardiovascular mortality.

No relevant association between coronary artery ectasia and mean platelet volume, gamma-glutamyltransferase and uric acid levels.

OBJECTIVES: In this study, we aimed to investigate whether there is an association between mean platelet volume (MPV), gamma-glutamyltransferase (GGT) and uric acid and coronary artery ectasia (CAE) in a large patient population. STUDY DESIGN: A total of 406 patients (245 male, 161 female; mean age: 55±9 years) were selected retrospectively as the study population from among 3265 individuals who underwent coronary angiography between August 2011 and December 2012. Information regarding blood tests of the patients obtained during hospitalization was extracted from the institute electronic database. RESULTS: MPV, GGT and uric acid levels were significantly higher in subjects with stenotic coronary artery disease (CAD) and in subjects with both CAD and CAE compared with subjects with isolated CAE and subjects with normal coronary arteries (NCA). There were no significant differences between the isolated CAE and NCA groups in terms of MPV (8.6±1.2 fL vs. 8.6±1.1, respectively, p=0.993), serum GGT (33±15 U/L vs. 30±15 U/L, respectively, p=0.723) and uric acid levels (5.4±1.6 mg/dl vs. 5.2±1.7 mg/dl, respectively, p=0.845). CONCLUSION: Unlike previous studies, our study failed to demonstrate any association between CAE and MPV, uric acid and GGT levels.

Increased plasminogen activator inhibitor-1 levels in patients with isolated coronary artery ectasia.

Isolated coronary artery ectasia (ICAE) is defined as the ectasia of the coronary arteries without concomitant coronary artery stenosis. The etiology and the clinical course of ICAE are still not clear. Increased levels of plasminogen activator inhibitor-1 (PAI-1) inhibit vasa vasorum, leading to diminished vessel wall supply and thus contributes to aortic aneurysm expansion. Whether the same process has role in coronary artery ectasia is not known. The aim of this study is to investigate the association between PAI-1 and coronary artery ectasia in patients without concomitant obstructive coronary artery disease. Among 2830 patients who underwent coronary angiography between March 2010 and 2011, 55 patients (40 male, 15 female, mean age 60 ± 8 years) with ICAE, formed our study group. 27 patients with similar patient characteristics, with angiographically proven normal coronary arteries, were enrolled as the control group. The basal characteristics were similar between two groups. PAI-1 levels were statistically higher in the ICAE group compared to the control group (104.13 ± 56.65 and 63.39 ± 35.01 ng/dl, respectively) (P = 0.008). A significant positive correlation between CAE and PAI-1 (r = 0.358, P = 0.007) was also demonstrated. Serum high sensitive C reactive protein (hsCRP) levels did not differ between two groups (P > 0.05). The plasma PAI-1 levels were significantly higher in ICAE patients compared to normal coronary artery group. Increased PAI-1 levels may diminish vasa vasorum by antiangiogenic activity leading to coronary ectasia.

Electrocardiographic findings of acute organophosphate poisoning.

In this study, we evaluated 85 patients who presented to our Emergency Department with organophosphate (OP) poisoning and discuss their associated electrocardiographic (ECG) abnormalities. Over a period of 3 years, 85 patients with OP poisoning were included in this retrospective study. ECG analysis included the rate, rhythm, ST-T abnormalities, conduction defects, and measurement of PR and QT intervals. The mean age was 32.2 +/- 14.9 years. Sixty percent of the patients were female. The mean corrected QT interval (QTc interval) was 0.435 +/- 0.052 s. Prolongation of the QTc interval (55.5%) was the most common ECG abnormality, followed by sinus tachycardia (31.8%). Elevation of the ST segment and low amplitude T waves were seen in 15 cases (17.6%). Patients with OP poisoning might reveal ECG abnormalities such as QTc interval prolongation or non-specific ST-T changes. QTc interval prolongation cannot be used as a unique predictive factor in determining short-term prognosis in OP poisoning. We found no clear relation between OP poisoning-related malignant ventricular dysrhythmia and QTc interval.

High levels of oxidative stress in patients with advanced lung cancer.

BACKGROUND AND OBJECTIVE: The aim of this study was to investigate oxidative stress status in different stages and histological types of lung cancer. METHODS: Forty-nine lung cancer patients, who had not received any therapy, and 20 healthy subjects were chosen for the study. Lung cancer patients were divided into those with early stage or advanced stage disease. The tumour type was adenocarcinoma in 24 patients, squamous cell carcinoma in 21 and large cell carcinoma in four. We measured serum nitrite, nitrate, ascorbic acid, retinol, beta-carotene and ceruloplasmin levels, and whole-blood malondialdehyde, reduced glutathione levels and catalase activity in patients with non-small cell lung carcinoma and healthy subjects. RESULTS: Statistically significant differences between the patient group and the control group were detected for all biochemical parameters. Mean malondialdehyde, nitrite, nitrate and ceruloplasmin levels and catalase activity were significantly higher in the group with advanced stage disease than in the control group. Mean beta-carotene, ascorbic acid and reduced glutathione levels were significantly lower in the group with advanced stage disease than in the control group. Mean malondialdehyde and nitrite levels were significantly higher in the patients with squamous cell carcinoma than in those with adenocarcinoma, and mean malondialdehyde level was also significantly higher in patients with squamous cell carcinoma than in those with large cell carcinoma. CONCLUSIONS: These results suggest that with advancing stage of lung cancer, the levels of oxidative stress increase, while levels of antioxidant molecules decrease. Patients with squamous cell carcinoma have higher oxidative stress as reflected by higher levels of malondialdehyde and nitrite.

Evaluation of myocardial perfusion and function by gated SPECT in patients with Behçet's disease.

BACKGROUND: Behçet's disease (BD) is a systemic multi-system vasculitis that can have a wide range of effects on the cardiovascular system. OBJECTIVE: To determine the existence of myocardial perfusion defects caused by coronary microvascular dysfunction in BD and to evaluate coronary arterial distribution and left ventricular systolic function by gated single-photon emission computed tomography (SPECT). METHODS: The study population consisted of 23 (15 men and 8 women) patients with BD and 20 healthy controls (12 men and 8 women). Technetium-99m methoxyisobutylisonitrile (Tc-99m MIBI) gated SPECT studies were performed at stress and rest in a 2-day protocol. Stress and rest left ventricular ejection fraction (LVEF) were calculated. Using non-gated SPECT images myocardial perfusion scores [summed stress score (SSS), summed rest score (SRS), summed difference score (SDS), and fix defect score (FDS)] and perfusion defect extent as percentage (stress, rest ischemic, and fix %LV) were determined. Using gated SPECT images, wall motion score indices (stress wall motion score indices and rest wall motion score indices) were calculated. Coronary angiography (CAG) was applied to patients with abnormal myocardial perfusion scintigraphy (MPS). RESULTS: The mean ages of the BD and control groups were 39.3 +/- 10.6 years and 36.2 +/- 8.3 years, respectively. No statistically significant differences were observed between the two groups regarding clinical features and cardiologic findings. Abnormal MPS was found in 13 (56.5%) of the BD patients; 3 patients had non-transmural infarcts and 10 patients reversible perfusion defects. Reversible perfusion defects were also found in two controls (10.0%). When the two groups were compared regarding the gated SPECT findings, differences were determined in the following parameters; SSS, SRS, SDS, FDS, stress and rest LVEF, stress and rest %LV, and stress and rest WMSI. In the BD group, when gated SPECT results were compared between those with and without abnormal MPS, differences were determined in SSS, SRS, SDS, FDS, stress and rest %LV, and stress and rest WMSI. Epicardial coronary arteries were normal in CAG. CONCLUSIONS: Myocardial perfusion and function are disturbed owing to influenced coronary microvascularity in BD, and CAG is frequently observed to be normal. Gated SPECT is a non-invasive reliable method that simultaneously evaluates the existence, extent and severity of myocardial ischemia or infarction and the wall movements in cardio-Behçet.

Effect of diphenhydramine on myocardial injury caused by organophosphate poisoning.

BACKGROUND: The aim of this experimental study was to investigate whether diphenhydramine could prevent or diminish myocardial injury caused by organophosphate poisoning as defined by histologic findings and cardiac troponin I (cTnI) levels. METHODS: Twenty-four Sprague-Dawley rats were divided into equal three groups. Group 1 did not receive any agent during the experiment. Group 2 received 0.8 g/kg fenthion subcutaneously followed by normal saline (3 ml/kg) intramuscularly 30 minutes later. Group 3 received 0.8 g/kg fenthion subcutaneously, followed by diphenhydramine 30 mg/kg (in 3 ml/kg) intramuscularly 30 minutes later. All rats underwent laparotomy and thoracotomy while under anesthesia at 24 hours. RESULTS: Treatment with diphenhydramine significantly decreased the blood cTnI levels. Additionally, diphenhydramine significantly reduced myocardial injury, including edema, inflammation, vacuolization and necrosis, as determined by pathologic scoring. CONCLUSION: Organophosphate poisoning can cause myocardial injury as determined by measurement of I cTnI levels. Our study demonstrates that this injury can be attenutated by the administration of diphenydramine.

Arterial stiffness and dipper/nondipper blood pressure status in women with preeclampsia.

INTRODUCTION: The aim of this study was to investigate the clinical relevance of dipper status in women with preeclampsia by comparing arterial stiffness index (SI) values, and dipper and nondipper status. METHODS: A total of 60 pregnant women in their third trimester were enrolled in the study. SI values were measured using a digital photoplethysmographic method (Pulse Trace System, Micro Medical Ltd., Gillingham, Kent, UK). Twenty-four-hour ambulatory blood pressure was measured by a SpaceLabs 90217 oscillometric device (SpaceLabs Inc., Redmond, WA, USA). Systolic blood pressure (SBP), diastolic blood pressure (DBP), mean arterial pressure (MAP), and pulse pressure (PP) were recorded. Those preeclamptic women whose mean nighttime blood pressure measurements were at least 10% lower compared with mean daytime measurements were classified as dipper status, and those with a decrease of less than 10% were classified as nondipper status. RESULTS: Seventeen women were preeclamptic with a dipper status, 13 women had nondipper status preeclampsia, and 30 women were normotensive. SI values were significantly higher in preeclamptic women compared with normotensive women (8.8+/-1.2 m/s vs. 5.9+/-0.8 m/s, P<0.001), but SI values of preeclamptic women with dipper status and preeclamptic women with nondipper status did not differ significantly from each other (P=0.485). CONCLUSION: There was no significant difference in SI values between the dipper and nondipper preeclamptic groups. These results indicate that dipper and nondipper measurements may not be suitable for clinical follow-up of preeclamptic women.

Carotid hemodynamic parameters in hemodialysis patients.

BACKGROUND: Atherosclerotic vascular disease is a major cause of morbidity and mortality for patients with end-stage renal disease on maintenance hemodialysis. Early atherosclerotic changes of the arterial wall can be evaluated by intima-media thickness (IMT), presence and structure of plaques and parameters of vascular resistance. The aim of the present study has been to investigate the relationship between carotid IMT and pulsatility index (PI) or resistive index (RI) values in hemodialysis patients. METHODS: We studied 36 hemodialysis patients (21 female, 15 male; median age 39.5 years, IQR 33.0-54.7 years) and 38 healthy volunteers (20 women, 18 men; median age 41.0 years IQR 32.5-53.5 years). All subjects underwent ultrasonography of common carotid artery, with determination of IMT, PI and RI. RESULTS: Bilateral and mean carotid IMT were found to be significantly higher in hemodialysis patients than in the control group (P<0.0001). Right and left carotid artery RI values were determined to be lower in hemodialysis patients than in the control group (P=0.007 for both). Similarly, right and left carotid PI values were also determined significantly lower in the hemodialysis group (P=0.005 and P=0.004, respectively). There was a moderate negative correlation between the right carotid IMT and right PI (r=-0.258, P=0.026). CONCLUSIONS: In contrast to previous studies in patients with diabetes, hypertension or cerebrovascular disease, PI and RI values decrease when IMT increases in hemodialysis patients. This finding may be a result of peripheral vasodilatation secondary to anemia in hemodialysis patients.

Congenital coronary artery fistula as a cause of angina pectoris.

Coronary arteriovenous fistula is an uncommon anomaly, representing an incidental finding in 0.1% to 0.2% of coronary angiograms. A 46-year-old man presented with a five-month history of palpitation and atypical stabbing chest pain on exertion and/or at rest. The electrocardiogram showed normal sinus rhythm, incomplete right bundle branch block with normal axis, and borderline left atrial abnormality. Echocardiography showed normal left ventricular function, mild left ventricular hypertrophy, moderate left atrial enlargement with mild mitral insufficiency, and moderate right atrial enlargement with mild-moderate tricuspid valve regurgitation. During exercise test, frequent ventricular ectopic beats were noted and the patient complained of atypical chest pain. Scintigraphy showed an ischemic defect in the inferior wall of the left ventricle. On coronary angiography, the right coronary artery and left anterior descending artery were normal, but the circumflex coronary artery was connected to the pulmonary artery through a congenital fistula. The patient refused any further intervention for fistula closure.

A case of acute myocardial infarction due to indirect lightning strike.

Lightning strike is a natural phenomenon with potentially devastating effects and represents one of the leading causes of cardiac arrest and death from environmental phenomena. Almost every organ system may be impaired as lightning passes through the human body preferring the pathways that the lowest resistance between the contact points. Lightning can also have widespread effects on the cardiovascular system, producing extensive catecholamine release or autonomic stimulation. The victim may develop hypertension, tachycardia, nonspecific electrocardiographic changes (including prolongation of the QT interval and transient T-wave inversion), and myocardial necrosis with release of creatine phosphokinase-MB fraction. We present the case of a 13-year-old boy with acute myocardial infarction secondary to an indirect lightning strike.

Relationship between serum 25-hydroxyvitamin D levels and the SYNTAX score in patients with acute coronary syndrome.

OBJECTIVE: The extent of severity and complexity of coronary artery disease (CAD) in patients presenting with ST-segment elevation myocardial infarction (STEMI) and non-STEMI (NSTEMI) and possible correlations between serum 25-hydroxyvitamin D (25(OH)D) have not yet been adequately studied. We evaluated the relationship between 25(OH)D levels and the burden of CAD as assessed by the SYNTAX score (SXscore) in patients with acute coronary syndrome (ACS) including STEMI and NSTEMI. METHODS: After exclusion, a total of 113 patients who were admitted to our hospital due to ACS and who were referred for undergoing coronary angiography were prospectively included. Their mean age was 63.3±18.5 years, and 80.5% of them were men. In total, 44.2% of the patients had NSTEMI and the remaining had STEMI. Blood samples were drawn at admission to evaluate serum 25(OH)D levels. CAD severity was assessed using the SXscore. Patients were classified as having low (SXscore ≤22) or high (SXscore >22) SXscores. Pearson's and Spearman's correlation coefficients were used to examine the relationship between serum 25(OH)D levels and the SXscore. RESULTS: 25(OH)D levels were significantly lower in the group with a high SXscore than in the group with a low SXscore (21.0±8.0 vs. 16.7±6.8, p=0.005). Correlation analysis showed a significant correlation between 25(OH)D levels and the SXscore. Multiple linear regression (MLR) analysis was used to determine the significance of the relationship between the SXscore and 25(OH)D, parathyroid hormone, and C-reactive protein levels and eGFR. MLR analysis revealed that only 25(OH)D levels (coefficient beta, -0.217, p=0.029) was significantly associated with the severity of CAD. CONCLUSION: The present study showed that serum 25(OH)D levels were significantly lower in patients with STEMI/NSTEMI and that low serum 25(OH)D levels were significantly correlated with CAD severity and extent.

The Relationship Between High-Sensitivity C-Reactive Protein Levels and Left Ventricular Hypertrophy in Patients With Newly Diagnosed Hypertension.

The authors aimed to evaluate the relationship between high-sensitivity C-reactive protein (hs-CRP) and presence of left ventricular hypertrophy and diastolic dysfunction in patients with hypertension. A total of 95 newly diagnosed hypertensive patients (mean age, 54±10 years) and 20 controls were included in this study. Patients were divided into four groups according to relative wall thickness as normal, concentric remodeling, concentric, and eccentric hypertrophy. hs-CRP was measured in all patients and serum hs-CRP level was shown to be increased in patients with hypertension compared with controls (0.57 mg/dL vs 0.25 mg/dL, respectively; P<.001). The hs-CRP level was highest in patients with concentric hypertrophy. When compared with controls, serum hs-CRP level was significantly higher in patients with concentric remodeling (0.61±0.3 mg/dL vs 0.43±0.5 mg/dL, P<.030) and concentric hypertrophy (0.69±0.3 mg/dL vs 0.43±0.5 mg/dL, P<.032). The present study shows that serum hs-CRP is significantly associated with left ventricular diastolic function and concentric hypertrophy in patients with hypertension.

Non alcoholic steatohepatitis is associated with subclinical impairment in left ventricular function measured by speckle tracking echocardiography.

OBJECTIVE: Nonalcoholic steatohepatitis (NASH) is a part of histological spectrum of nonalcoholic fatty liver disease (NAFLD). Higher incidence of cardiovascular mortality has been reported in studies including patients with NAFLD. Impaired myocardial function can be detected by a novel echocardiographic method called speckle tracking echocardiography (STE) when conventional methods were normal. METHODS: Twenty-eight biopsy-proven NASH patients (mean age 41.6 ± 9.8, 16 male) without hypertension and diabetes mellitus were included in study. All patients underwent transthoracic echocardiography. Offline analyses of images was performed and strain (S), strain rate (SR) parameters compared between NASH patients and controls. Statistical analysis were done by independent samples t test between groups and a multiple linear regression model was used to identify the statistical significance of relationships between selected variables. RESULTS: R(SR-S) values were similar but R(S), R(SR-E), R(SR-E/A) values were significantly lower and R(SR-A) was higher in the NASH patients. There were no significant differences in CS, C(SR-S), C(SR-E), C(SR-A) and C(SR-E/A) values among the two groups. The most impressive results were obtained from longitudinal strain and strain rate parameters. LS, L(SR-S), L(SR-E), L(SR-A), values were significantly lower in NASH group when compared with healty controls. Linear regression analysis showed that RS and LS was not associated with diastolic blood pressure, total cholesterol and LDL cholesterol. CONCLUSION: The LV longitudinal and radial systolic functions may be deteriorated in patients with NASH even in the absence of apparent decrease in the LV ejection fraction. STE may be useful in detecting preclinical LV impairment in patients with NASH.

Acute Effects of Intracoronary Tirofiban on No-Reflow Phenomena in Patients With ST-Segment Elevated Myocardial Infarction Undergoing Primary Percutaneous Coronary Intervention.

We evaluated the acute effect of intracoronary administration of tirofiban on no-reflow phenomenon in patients with ST-segment elevated myocardial infarction undergoing primary percutaneous coronary intervention. Consecutive patients (n = 162) were randomized into 2 groups based on whether intracoronary tirofiban was administered. After the administration of intracoronary tirofiban, thrombolysis in myocardial infarction (TIMI) flow grade significantly increased (P < .001) and successful reperfusion was achieved in 26 (32%) patients. In the placebo group, however, after the administration of intracoronary placebo the TIMI flow grade did not change (P = .070), and successful reperfusion was achieved only in 8 (10%) patients. In-hospital major adverse cardiac events (MACE) were significantly lower in the tirofiban group (36% vs 19%, P = .013). Intracoronary administration of tirofiban significantly improves TIMI flow grade and is associated with a lower in-hospital rate of MACE.
