Cardiovascular outcomes of complex bifurcation lesions following double kissing crush or nano-crush techniques: The multicenter EVOLUTE-CRUSH V study.

BACKGROUND: Double kissing crush (DKC) and nano-crush (NC) techniques are frequently used, but the comparison for both techniques is still lacking. The goal of this multicenter study was to retrospectively assess the midterm clinical results of DKC and NC stenting in patients with complex bifurcation lesions (CBLs). METHODS: A total of 324 consecutive patients [male: 245 (75.6%), mean age: 60.73 ± 10.21 years] who underwent bifurcation percutaneous coronary intervention between January 2019 and May 2023 were included. The primary endpoint defined as the major cardiovascular events (MACE) included cardiac death, target vessel myocardial infarction (TVMI), or clinically driven target lesion revascularization (TLR). Inverse probability weighting (IPW) was performed to reduce treatment selection bias. This is the first report comparing the clinical outcomes of DKC and NC stenting in patients with CBL. RESULTS: The initial revascularization strategy was DKC in 216 (66.7%) cases and NC in 108 (33.3%) patients. SYNTAX scores [25.5 ± 6.73 vs. 23.32 ± 6.22, p = 0.005] were notably higher in the NC group than the DKC group. The procedure time (76.98 ± 25.1 vs. 57.5 ± 22.99 min, p = 0.001) was notably higher in the DKC group. The incidence of MACE (18.5 vs. 9.7%, p = 0.025), clinically driven TLR (14.8 vs. 6%, p = 0.009), and TVMI (10.2 vs. 4.2%, p = 0.048) were notably higher in the NC group than in the DKC group. The midterm MACE rate in the overall population notably differed between the NC group and the DKC group (adjusted HR (IPW): 2.712, [95% CI: 1.407-5.228], p = 0.003). CONCLUSION: In patients with CBLs, applying the DKC technique for bifurcation treatment had better ischemia-driven outcomes than the NC technique.

The association between CHA2DS2-VASc score and erectile dysfunction: a cross-sectional study.

PURPOSE: This study aims to assess the association between CHA2DS2-VASc score and erectile dysfunction in patients who were admitted to cardiology outpatient clinics. MATERIALS AND METHODS: One hundred and two male patients who were admitted to the cardiology outpatient clinic were included to the study. Erectile dysfunction was evaluated in the urology outpatient clinic in the same hospital and scored using Turkish Version of The International Index of Erectile Function. CHA2DS2-VASc score was calculated for every patient using the current associated guidelines. RESULTS: There was a negative correlation between The International Index of Erectile Function score and CHA2DS2-VASc score, age, hypertension, heart failure, diabetes mellitus, stroke respectively. Smoking and dislipidemia were not correlated with The International Index of Erectile Function score (p>0.05). CONCLUSION: CHA2DS2-VASc score can be used to detect Erectile dysfunction in patients who are admitted to the cardiology outpatient clinics.

Impaired aortic elastic properties in young females with migraine.

UNLABELLED: Migraine is a common health problem affecting women more commonly. It has been associated with an increased risk for cardiovascular events. In this study, we investigated whether aortic elastic properties is altered in migraineurs with low cardiovascular risk compared with healthy controls, in order to elicit further evidence on tentative association between migraine and increased risk of cardiovascular disease. METHODS: Forty-three migraine patients with low CVD risk were enrolled to the study. Thirty-three volunteers, with a similar age and sex distribution served as a control group. Following parameters of the aortic elasticity were calculated: aortic strain, aortic stiffness (beta) index and aortic distensibility. RESULTS: Aortic strain was not statistically different between the study and control group. However, aortic distensibility and beta index were significantly impaired in patients with migraine compared to control subjects DISCUSSION: The elastic properties of the aorta in migreineurs may be different from normal by using easily available echocardiographic methods. This information may be a clue for clarification of cardiovascular system involvement in migraine.

A rare cause of chest pain mimicking myocardial infarction.

We present a patient who underwent endoscopic retrograde cholangiopancreatography procedure for bile duct stone removal and sphincterotomy. Upon completion of the procedure, the patient experienced severe chest pain. Because myocardial infarction was the likely diagnosis, we immediately performed a coronary angiography, which identified severe coronary lesions without any total occlusion. Being skeptical of the possible cause, we searched for alternative causes and interestingly found pneumothorax, pneumomediastinum, and retro-intra-abdominal free air. This rare complication is particularly important for a cardiologist because they should be aware of such a complication, and correlation with the symptoms and coronary lesions should always be made.

The role of electrocardiography in evaluation of severity of chronic obstructive pulmonary disease in daily clinical practice.

INTRODUCTION: Chronic obstructive pulmonary disease (COPD) is the fourth leading cause of chronic morbidity and mortality. Bronchial obstruction and increased pulmonary vascular resistance impairs right atrial functions. In this study, we aimed to investigate the effect of bronchial obstruction on p wave axis in patients with COPD and usefulness of electrocardiography (ECG) in the evaluation of the severity of COPD. PATIENTS AND METHODS: Ninety five patients (64 male and 31 female) included to the study. Patients were in sinus rhythm, with normal ejection fraction and heart chamber sizes. Their respiratory function tests and 12 lead electrocardiograms were obtained at same day. Correlations with severity of COPD and ECG findings including p wave axis, p wave duration, QRS axis, QRS duration were studied. RESULTS: The mean age was 58 ± 12 years. Their mean p wave axis was 62 ± 18 degrees. In this study, p wave axis has demonstrated significant positive correlations with stages of COPD and QRS axis but significant negative correlations with FEV1, FEF, BMI and QRS duration. P wave axis increases with increasing stages of COPD. CONCLUSION: Verticalization of the frontal p wave axis may be an early finding of worsening of COPD before occurrences of other ECG changes of hypertrophy and enlargement of right heart chambers such as p pulmonale. Verticalization of the frontal p wave axis reflecting right atrial electrical activity and right heart strain may be a useful parameter for quick estimation of the severity of COPD in an out-patient cared.

Serum uric acid level is associated with cardiac hypertrophy in renal transplant recipients.

BACKGROUND: Serum uric acid (UA) level as a significant and independent risk factor for cardiovascular disease, and the link between this marker and left ventricular hypertrophy (LVH) in renal transplant recipients remains to be clarified. METHODS: A total of 141 renal transplant recipients (83 men), between ages of 18 and 69 (mean age 37 ± 11), were included in this single center study. In addition to demographic, clinical, and laboratory parameters, serum UA concentrations were evaluated. LVH was determined by two-dimensional and M-mode echocardiography. RESULTS: Serum UA levels were significantly higher (6.14 ± 1.15 mg/dL) in patients with LVH (n = 54) when compared to patients (n = 87) who did not have this abnormality (5.29 ± 1.43 mg/dL) (p = 0.006). Serum UA levels were significantly correlated with septal wall thickness, LV posterior wall thickness, LV mass index (LVMI), and pulmonary arterial pressure. Multiple linear regression analysis revealed that UA predicted LVMI (r(2) = 0.150, ß = 0.369, p = 0.001). However, serum creatinine (ß = 0.060, p = 0.593) and age (ß = 0.146, p = 0.175) were not predictors of LVMI. CONCLUSION: High serum UA levels are associated with LVH in renal transplant recipients, which underlines the importance of treating hyperuricemia.

Cytotoxic T lymphocyte antigen-4 (CTLA-4) A49G polymorphism and autoimmune blood diseases.

OBJECTIVE: The cytotoxic T lymphocyte associated antigen-4 (CTLA-4) is expressed on T lymphocytes, and inhibits the T-cell responses. In animal models, it has been shown that complete CTLA-4 deficiency was lethal due to massive infiltration of tissues by polyclonally proliferating lymphocytes. CTLA-4 A49G polymorphism, which has been suggested to reduce the inhibitory function of the CTLA-4 molecule, was found to be associated with various autoimmune diseases in recent studies. METHODS: In this study, we evaluated the frequency of CTLA-4 A49G polymorphism in 46 patients with autoimmune hemolytic anemia (AIHA), 62 patients with immune thrombocytopenic purpura (ITP), and 150 healthy individuals. RESULTS: Allele frequencies and genotype distributions were similar in both ITP and AIHA patients compared to healthy individuals. In subgroup analysis, however, we found that in chronic lymphocytic leukemia (CLL) patients with AIHA (n=4), all patients had CTLA-4 A49G polymorphism (3 had AG, 1 had GG). There was no significant statistical association between G allele and systemic lupus erythematosus (SLE) or AIHA. CONCLUSION: These data suggest that CTLA-4 A49G polymorphism does not contribute to the pathogenesis of lymphoproliferative diseases itself, nor does it increase the risk of autoimmune complications in patients with lymphoproliferative disease.

Neutrophil to lymphocyte ratio and platelet to lymphocyte ratio are associated with cryptogenic stroke in patients with patent foramen ovale.

INTRODUCTION: Although most ischaemic strokes are due to cardioembolism, about 25-40% of strokes are cryptogenic. Patent foramen ovale has been associated with cryptogenic stroke; however, the precise mechanism of this association has not been demonstrated. The aim of this study was to evaluate the association between inflammatory markers and cryptogenic stroke in patients with patent foramen ovale. MATERIAL AND METHODS: We included 206 patients with patent foramen ovale. Ninety-four (45.63%) out of 206 patients had had stroke, and 112 (54.37%) had not had stroke. The ratio of the total neutrophil count to the total lymphocyte count was defined as the neutrophil to lymphocyte ratio, and the ratio of the absolute platelet count to the absolute lymphocyte count was determined as the platelet to lymphocyte count. RESULTS: The neutrophil to lymphocyte ratio was significantly higher in patients who had stroke than in those who did not (2.41 ±1.69 vs. 2.19 ±1.74, p = 0.047). Although the platelet to lymphocyte count was also higher in patients who had had stroke than in those who had not, it was not statistically significant (120.94 ±55.45 vs. 118.01 ±52.21, p = 0.729). 1.62 was the cut-off value for neutrophil to lymphocyte ratio to be associated with stroke with 73.4% sensitivity and 45.05% specificity (p = 0.042). CONCLUSIONS: This study demonstrated that elevated neutrophil to lymphocyte ratio and platelet to lymphocyte count could be associated with cryptogenic stroke in patients with patent foramen ovale.

The association of neutrophil to lymphocyte ratio and TIMI frame count in primary percutaneous coronary intervention.

BACKGROUND: This study was sought to evaluate the relationship between admission neutrophil lymphocyte ratio (NLR) and estimated coronary flow by the TIMI frame count (TFC) method in patients with ST-segment elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention (PPCI). METHODS: TFC of 262 consecutive STEMI patients were evaluated after PPCI. Admission NLR were calculated and TFC was determined after PPCI. According to admission NLR value, patients were divided in to two groups. NLR levels higher than 3.5 were defined "higher NLR" whereas lower than 3.5 were accepted as "lower NLR". RESULTS: TFC was significantly higher in patients with higher NLR (56.6±41.1 vs. 37.9±36.1, P<0.001). No-reflow phenomenon was more frequent in higher NLR group compared to lower NLR group (10.1% vs. 5.2%, P=0.001). In multivariate linear regression analysis admission NLR was an independent predictor of high TIMI frame count (B=2.24 95 % CI (1.17-3.31), P<0.001). CONCLUSIONS: Our findings suggest that admission NLR predicts coronary blood flow in means of TFC.

Serum Presepsin Levels Are Not Elevated in Patients with Controlled Hypertension.

INTRODUCTION: Hypertension (HT) is a common serious condition associated with cardiovascular morbidity and mortality. The pathogenesis of HT is multifactorial and has been widely investigated. Besides the vascular, hormonal, and neurological factors, inflammation plays a crucial role in HT. Many inflammatory markers such as C-reactive protein, cytokines, and adhesion molecules have been studied in HT, which supported the role of inflammation in the pathogenesis of HT. Presepsin (PSP) is a novel biomarker of inflammation. Therefore, the potential relationship between PSP and HT was investigated in this study. METHODS: Forty-eight patients with controlled HT and 48 controls without HT were included in our study. Besides routine clinical and laboratory data, PSP levels were measured in peripheral venous blood samples from all the participants. RESULTS: PSP levels were significantly lower in patients with HT than in controls (144.98 ± 75.98 versus 176.67 ± 48.12 pg/mL, p = 0.011). PSP levels were positively correlated with hsCRP among both the patient and the control groups (p = 0.015 and p = 0.009, resp.). However, PSP levels were not correlated with WBC among both groups (p = 0.09 and p = 0.67, resp.). CONCLUSIONS: PSP levels are not elevated in patients with well-controlled HT compared to controls. This result may be associated with anti-inflammatory effects of antihypertensive medicines.

The Association Between α1-Antitrypsin and Coronary Artery Ectasia.

Coronary artery ectasia (CAE) is associated with coronary artery disease (CAD). The underlying pathophysiology of CAE is not fully understood. α1-antitrypsin (A1AT) plays a role in the tissue protease system, and AAT-1 deficiency (A1ATD) has been shown to be related to CAD. We compared A1AT serum levels in patients with and without CAE to determine the association between A1AT levels and the extent of ectasia using the Markis score. We included 50 patients (38 males) with isolated CAE and 46 patients (28 males) with normal coronary arteries after coronary angiography. The levels of A1AT were measured by nephelometry. The median A1AT levels were lower in patients with isolated CAE than in the control group (1.27 ng/mL [range: 1.07-1.37 ng/mL] vs 1.43 ng/mL [range: 1.27-1.59 ng/mL]; P < .001). According to the Markis classification, the extent of CAE was not correlated with A1AT levels ( P = .41). Our results demonstrate an inverse relationship between serum A1AT levels and CAE. α1-antitrypsin is fundamental for the stability and integrity of the arterial wall. Lack of elastase inhibition in cases of A1ATD may contribute to ectasia formation by facilitating proteolysis and weakening the arterial wall.

Usefulness of the uric acid and CHA2DS2-VASc score in prediction of left atrial thrombosis in patients with mitral stenosis and sinus rhythm.

BACKGROUND: The risk of thrombus formation in the left atrium is known to be very high in patients with both mitral stenosis (MS) and atrial fibrillation (AF). However, that risk should not be ignored in patients with MS in sinus rhythm (SR). The aim of this study was to determine the clinical, echocardiographic, and biochemical factors that could have a determining role in the formation of a left atrial (LA) thrombus in patients with MS in SR. METHOD: A total of 207 consecutive patients with MS who underwent both transthoracic echocardiography (TTE) and transesophageal echocardiography (TEE) for diagnosis or to investigate the presence of a thrombus in the LA and appendage were enrolled in this study. RESULTS: LA thrombus was detected in 21 of 207 patients. CHA2DS2-VASc score was not found to be a predictor of LA thrombosis in patients with MS in SR, despite the higher CHA2DS2-VASc scores observed in those patients. The mitral valve area and mitral valve gradient were not predictive of LA thrombus development; however, LA anteroposterior diameter (LAAPD) was found to be a predictor of LA thrombosis. Levels of high sensitivity-C-reactive protein and uric acid were higher in the patients with LA thrombosis, but only uric acid was found to be a predictor of LA thrombosis in multivariate analysis. CONCLUSIONS: A larger LAAPD and an elevated serum uric acid level were found to be independent predictors of LA thrombosis in patients with MS in SR.

Evaluation of lipoprotein-associated phosholipase A2 and plaque burden/composition in young adults.

OBJECTIVE: The total burden of subclinical coronary atherosclerosis is significant in young adults. Serum lipoprotein-associated phospholipase A2 (Lp-PLA2) is an established predictor of morbidity and mortality because of cardiovascular disease. The aim of the present investigation was to evaluate the relationship between subclinical coronary atherosclerosis and serum Lp-PLA2 concentrations in a population of young adults. PATIENTS AND METHODS: A total of 261 individuals younger than 45 years of age who had undergone coronary computed tomography angiography were evaluated. The study group included 101 patients in whom coronary computed tomography angiography detected subclinical coronary atherosclerosis; the control group included 160 sex-matched and age-matched healthy control patients. RESULTS: Serum Lp-PLA2 levels were increased significantly in the study group patients compared with the control patients (15.42±11.88 vs. 8.06±4.32 ng/ml, P<0.001). Furthermore, a positive correlation was identified between the Lp-PLA2 levels and the total number of plaques and diseased arteries (r=0.495, P<0.001, and r=0.621, P<0.001, respectively). The presence of mixed plaque composition was also correlated with the Lp-PLA2 levels (r=0.657, P<0.001). Multivariate regression analysis identified four independently significant predictors of subclinical coronary atherosclerosis: high-sensitivity C-reactive protein levels, tobacco use, uric acid levels, and serum Lp-PLA2 levels. CONCLUSION: The presence of subclinical coronary atherosclerosis is associated independently with Lp-PLA2, and it has potential utility as a novel indicator of cardiovascular disease risk in the young adult population.

A comparative analysis of leukocyte and leukocyte subtype counts among isolated systolic hypertensive, systo-diastolic hypertensive, and non-hypertensive patients.

BACKGROUND: Isolated systolic hypertension (ISHT) is a subtype of hypertension (HT) that often exhibits wide pulse pressure, and pulse pressure has a strong predictive value for future adverse cardiovascular events. Previous studies have shown the effects of leukocyte count on the prognosis of ischaemic heart disease and HT. AIM: Thus, in this cross-sectional study, we analysed the relationship between leukocyte counts and subtypes in HT and non-HT groups. METHODS: The study population consisted of 960 consecutive patients who were admitted to the outpatient clinic of our hospital. After ambulatory blood pressure values were assessed, the participants were divided into three groups: ISHT (n = 98), systo-diastolic hypertensives (SDHT, n = 405), and non-hypertensives (non-HT, n = 457). RESULTS: The subjects in the ISHT group were older than those in the SDHT and non-HT groups (64 ± 10, 53 ± 12, and 52 ± 13, respectively; p < 0.001). The leukocyte and neutrophil counts and neutrophil/lymphocyte (NL) ratios were significantly different in all groups. In subgroup analysis, the leukocyte count, neutrophil count, and N/L ratio were higher in the ISHT and SDHT groups than in the non-HT group (p < 0.001 for all). The leukocyte count, neutrophil count, and N/L ratio were significantly higher in the ISHT group than in the SDHT group (p = 0.023, p = 0.007, p = 0.010, respectively). Neutrophil count (p = 0.012; OR = 1.229, 95% CI 1.046-1.444) was an independent risk factor for ISHT in multivariate logistic regression analysis. CONCLUSIONS: The leukocyte and neutrophil counts and N/L ratios were higher in the ISHT group than in the SDHT and non-HT groups. High neutrophil count was an independent predictor of ISHT.

Comparison of different strategies of ivabradine premedication for heart rate reduction before coronary computed tomography angiography.

OBJECTIVE: The aim of this study was to assess the effectiveness and safety of different strategies of ivabradine therapy by comparing the effects on heart rate (HR), blood pressure (BP), and image quality of coronary CT angiography (CTA). METHODS: A total of 192 consecutive patients were randomly assigned to 3 groups of oral premedication with ivabradine 15 mg (single dose), 10 mg (single dose), and 5 mg twice daily for 5 days, prospectively. Patients using HR-lowering drugs and patients with ß-blockade contraindication were excluded. The target HR was 65 beats/min. In addition 5 to 10 mg of intravenous metoprolol was administered to the patients at the CT unit, if required. The systolic and diastolic blood BP values and the HRs were recorded. Image quality was assessed for 8 of 15 coronary segments with a 4-point grading scale. Results were compared with the Kruskal-Wallis test, one-way ANOVA, and χ2 test. RESULTS: Reductions in mean HR after the treatment were 18 ± 6, 14 ± 4, and 17 ± 7 beats/min for groups 1, 2, and 3, respectively. With the total additional therapies, 81.3%, 67.2%, and 84.3% of the patients achieved HR < 65 beats/min in groups 1, 2, and 3, respectively. The mean BP values before coronary CTA were not significantly changed except for patients in group 2. Unacceptable (score 0) image quality was obtained in only 4.5%, 10.2%, and 4.2% of all the coronary segments, in groups 1, 2, and 3, respectively. CONCLUSIONS: Our study indicates that coronary CTA with premedication with oral ivabradine in all 3 strategies is safe and effective in reducing HR, in particular with a ß-blockade combination. All 3 ivabradine regimes may be an alternative strategy for HR lowering in patients undergoing coronary CTA. Ivabradine 15 mg (single dose) and ivabradine 5 mg twice daily for 5 days are superior to the ivabradine 10-mg single-dose regime for HR lowering without adjunctive intravenous ß-blocker usage.

The role of the neutrophil/lymphocyte ratio in patients with rheumatic mitral stenosis as an indicator of spontaneous echocardiographic contrast.

BACKGROUND: Although it has declined in developed countries, mitral valve stenosis is problematic in developing countries; its main cause is rheumatic fever. In patients with rheumatic mitral stenosis (RMS), ongoing chronic inflammation may resultin the progression of valvular damage and the formation of spontaneous echocardiographic contrast (SEC). AIM: We investigated the role of the neutrophil/lymphocyte ratio (NLR) as an indicator of ongoing inflammation and independentpredictive risk factor for SEC in RMS patients. METHODS: A total of 112 patients (mean age 46 ± 10.6; 73.2% female) with RMS who underwent both transthoracic echocardiography and transoesophageal echocardiography were enrolled; the control group comprised 100 healthy volunteers (mean age 44 ± 9.1; 62% female). Patients were divided into two subgroups according to the formation of SEC in the left atrium and appendage. Haematological and biochemical indices were measured in all patients and controls. RESULT: NLR was higher in the patients than controls (2.6 ± 1.15 vs. 1.71 ± 0.53, p < 0.001). In addition, it was higher in the SEC-positive group (mean age 47 ± 10.3; 68.4% female) compared to the SEC-negative group (mean age 44 ± 10.7; 78.2% female; 3.21 ± 1.25 vs. 1.97 ± 0.55, p < 0.001). In multivariate analysis, NLR (odds ratio [OR] 20.602, 95% confidence interval [CI] 4.678­90.731; p < 0.001) and left atrial diameter (OR 5.966, 95% CI 2.166­16.429; p = 0.01) were found tobe independent predictors of SEC in RMS patients. CONCLUSIONS: RMS patients exhibit on-going inflammation; NLR is a good marker of this. The formation of SEC is associated with inflammation and NLR is an independent predictive risk factor for SEC.

The association between CHA2DS2-VASc score and erectile dysfunction: a cross-sectional study

ABSTRACT Purpose: This study aims to assess the association between CHA2DS2-VASc score and erectile dysfunction in patients who were admitted to cardiology outpatient clinics. Materials and methods: One hundred and two male patients who were admitted to the cardiology outpatient clinic were included to the study. Erectile dysfunction was evaluated in the urology outpatient clinic in the same hospital and scored using Turkish Version of The International Index of Erectile Function. CHA2DS2-VASc score was calculated for every patient using the current associated guidelines. Results: There was a negative correlation between The International Index of Erectile Function score and CHA2DS2-VASc score, age, hypertension, heart failure, diabetes mellitus, stroke respectively. Smoking and dislipidemia were not correlated with The International Index of Erectile Function score (p>0.05). Conclusion: CHA2DS2-VASc score can be used to detect Erectile dysfunction in patients who are admitted to the cardiology outpatient clinics.

The relationship between γ-glutamyl transferase levels and the clinical outcomes in patients with ST-segment elevation myocardial infarction undergoing primary percutaneous coronary intervention.

OBJECTIVES: Serum γ-glutamyl transferase (GGT) activity has been shown to be related to the development of atherosclerosis and cardiovascular events. The aim of this study was to evaluate the prognostic value of GGT in patients with ST-segment elevation myocardial infarction (STEMI) undergoing a primary percutaneous coronary intervention (PCI). PATIENTS AND METHODS: A total of 683 consecutive patients with STEMI who underwent primary PCI were evaluated. The study population was divided into tertiles on the basis of admission GGT values. A high GGT (n=221) was defined as a value in the upper third tertile (GGT>37) and a low GGT (n=462) was defined as any value in the lower two tertiles (GGT≤37). The mean follow-up time was 29 months. RESULTS: The in-hospital mortality rate was significantly higher in patients in the high GGT group (7.2 vs. 1.7%, P<0.001), as was the rate of adverse outcomes in patients with high GGT levels. In multivariate analyses, a significant association was found between high GGT levels and adjusted risk of in-hospital cardiovascular mortality (odds ratio=8.6, 95% confidence interval: 2.3-32.4, P=0.001). In a receiver operating characteristic curve analysis, a GGT value greater than 37 was identified as an effective cutoff point in STEMI for in-hospital cardiovascular mortality (area under curve=0.71, 95% confidence interval: 0.59-0.82, P<0.001). There were no differences in the long-term adverse outcome rates between the two groups. CONCLUSION: GGT is a readily available clinical laboratory value associated with in-hospital adverse outcomes in patients with STEMI who undergo primary PCI. However, there was no association with long-term mortality.

Admission hyperglycemia and TIMI frame count in primary percutaneous coronary intervention.

We evaluated the relationship between admission blood glucose levels and estimated coronary flow by the thrombolysis in myocardial infarction (TIMI) frame count (TFC) method in patients with ST-segment elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention (pPCI). The TFC of 121 consecutive patients with STEMI were evaluated after pPCI. Patients with admission glucose levels > 198 mg/dL (11 mmol/L) were defined as hyperglycemic. Hyperglycemia was observed in 36 (29.8%) patients. The TFC was significantly higher in patients with hyperglycemia (70.75 [10-96] vs 56.87 [8-100], P = .04). No-reflow frequency was higher in the hyperglycemia group (44.4% vs 23.5%, P = .02). In multivariate linear regression analysis admission glucose was an independent predictor of high TFC (B = 0.21, P = .02). Our findings suggest that admission blood glucose is a predictor of TFC which reflects coronary blood flow.

Effects of arteriovenous fistula on clinical, laboratory and echocardiographic findings in renal allograft recipients.

PURPOSE: Left ventricular hypertrophy (LVH) is frequently observed in patients with end-stage renal disease and renal allograft recipients, and is an independent and strong predictor of morbidity and mortality. Presence of a patent arteriovenous fistula (AVF) after renal transplantation may contribute to the persistent LVH. We investigated the clinical, laboratory, and echocardiographic findings in patients with renal transplants with or without AVF. METHODS: A total of 130 renal transplant recipients were included in this study: 60 hemodialysis patients whose fistulas were still functional, 49 hemodialysis patients whose fistulas were spontaneous stopped or closed, and 21 peritoneal dialysis patients who had never had fistulas created. Laboratory parameters were measured and echocardiographic measurements were performed. RESULTS: There were no significant differences regarding smoking status, blood pressures, or NT-proBNP, hs-CRP, iPTH, and TSH levels between the study groups. Left atrial, right atrial diameters, left ventricle end-diastolic diameter, left ventricle end-systolic diameter, interventricular septum thickness (IVST), left ventricle mass index (LVMI), pulmonary artery pressure (PAP), and ejection fraction were similar in the three groups. In correlation analysis, PAP was significantly correlated with serum uric acid and NT-proBNP levels. Also, there were positive and moderate correlations between the serum uric acid and the IVST. CONCLUSION: Patent AVFs have not affected cardiovascular abnormalities such as LVH and LV mass index in patients with renal transplant. Hyperuricemia may be associated with increased PAP and high LVMI.
