The effect of periodontal therapy on neopterin and vascular cell adhesion molecule-1 levels in chronic periodontitis patients with and without acute myocardial infarction: a case-control study

Abstract The presence of neopterin in gingival crevicular fluid (GCF) is a marker for local and acute immune activation, and the presence of vascular cell adhesion molecule (VCAM-1) in GCF is accepted as a marker for chronic vascular inflammation. Objectives This study aimed to evaluate effects of periodontal treatment on GCF levels of neopterin and VCAM-1 in patients with chronic periodontitis (CP) with acute myocardial infarction (AMI) compared with systemically healthy CP patients. Material and methods Sixty subjects (20 CP patients with AMI, 20 healthy CP patients, and 20 healthy controls) were included. GCF samples were analyzed at baseline and after 3 and 6 months, and the probing pocket depth (PD), clinical attachment level (CAL), bleeding on probing, gingival (GI) and plaque (PI) indices were recorded. We determined neopterin and VCAM-1 levels (concentration and total amount) using enzyme-linked immunosorbent assay (ELISA). No significant differences were seen between the AMI+CP and CP groups for PI, GI, GCF levels of neopterin and VCAM-1 at baseline. Results The number of teeth with 5 mm≤CAL<7 mm and CAL≥7 mm were significantly increased in the AMI+CP group at baseline. There were no significant differences between the AMI+CP and CP for PI, CAL, GCF volumes, and the AMI+CP group had the highest clinical improvement in the number of teeth with 5 mm≤CAL<7 mm at the sixth month. There were significant positive correlations between clinical periodontal inflammation and the presence of neopterin and VCAM-1 in GCF prior to and following periodontal treatment, and between the GCF volume and clinical parameters. Conclusions Data suggest that the total amount and concentration of neopterin and VCAM-1 in GCF seemed to be closely associated with periodontal disease severity in CP patients with AMI. Moreover, the results of our study demonstrate that the past periodontal status is potentially correlated between groups, with similar periodontal disease severity.

Preliminary results from a nationwide adult cardiology perspective for pulmonary hypertension: RegiStry on clInical outcoMe and sUrvival in pulmonaRy hypertension Groups (SIMURG).

OBJECTIVE: The present study was designed to evaluate the characteristics of pulmonary hypertension (PH) and adult cardiology practice patterns for PH in our country. METHODS: We evaluated preliminary survey data of 1501 patients with PH (females, 69%; age, 44.8±5.45) from 20 adult cardiology centers (AdCCs). RESULTS: The average experience of AdCCs in diagnosing and treating patients with PH was 8.5±3.7 years. Pulmonary arterial hypertension (PAH) was the most frequent group (69%) followed by group 4 PH (19%), group 3 PH (8%), and combined pre- and post-capillary PH (4%). PAH associated with congenital heart disease (APAH-CHD) was the most frequent subgroup (47%) of PAH. Most of the patients' functional class (FC) at the time of diagnosis was III. The right heart catheterization (RHC) rate was 11.9±11.6 per month. Most frequently used vasoreactivity agent was intravenous adenosine (60%). All patients under targeted treatments were periodically for FC, six-minute walking test, and echo measures at 3-month intervals. AdCCs repeated RHC in case of clinical worsening (CW). The annual rate of hospitalization was 14.9±19.5. In-hospital use of intravenous iloprost reported from 16 AdCCs in CWs. Bosentan and ambrisentan, as monotreatment or combination treatment (CT), were noted in 845 and 28 patients, respectively, and inhaled iloprost, subcutaneous treprostinil, and intravenous epoprostenol were noted in 283, 30, and four patients, respectively. Bosentan was the first agent used for CT in all AdCCs and iloprost was the second. Routine use of antiaggregant, anticoagulant, and pneumococcal and influenza prophylaxis were restricted in only two AdCCs. CONCLUSION: Our nationwide data illustrate the current status of PH regarding clinical characteristics and practice patterns.

Acute myocardial infarction as a finding of acute promyelocytic leukemia-related coagulation disorder.

Acute promyelocytic leukemia (APL) has one of the most favorable prognoses among other leukemia subtypes. However, the major cause of mortality in APL is disseminated intravascular coagulation at the presentation. We present a case of acute myocardial infarction (MI) at the time of APL diagnosis before treatment. The patient suffered from chest pain, sweating and giddiness. He was hypoxic, hypotensive and bradycardic. ECG showed inferior MI. Unfractioned heparin infusion (850 U/h) was started and 5 min after the previous ECG showed total ST resolution. We suggest that in this case, MI was not related to atherosclerotic plaque rupture but related to DIC manifestation.

Dasatinib-induced pulmonary hypertension in acute lymphoblastic leukemia: case report.

Pulmonary hypertension (PHT) is a pathological condition determined as an increase in mean pulmonary arterial pressure ≥25 mmHg. Pulmonary arterial hypertension (PAH) is precapillary PHT and a life-threatening disease group which consists of different etiologies with the same pathological and clinical findings, and which is characterized by elevated pulmonary vascular resistance. Dasatinib is a dual Src/Abl kinase inhibitor associated with higher affinity for BCR/ABL kinase than imatinib, and is used in the treatment of chronic myelocytic leukemia and Philadelphia chromosome positive acute lymphoblastic leukemia (ALL). We describe a case with ALL, in whom dasatinib treatment induced PAH, and who recovered with bosentan treatment.

Assessment of right ventricular functions during cancer chemotherapy.

AIMS: Although systolic and diastolic left ventricular functions after cancer chemotherapy are well studied, there are a few investigations about the right ventricular functions. We aimed to investigate the early effects of chemotherapy on right heart, if any, in addition to the association between N-terminal pro-brain natriuretic peptide (NT-proBNP) and right heart echocardiographic indices. METHODS AND RESULTS: Thirty-seven consecutive patients with newly diagnosed breast cancer who were planned to receive either AC protocol [cyclophosphamide (600 mg/m(2)) + adriamycin (60 mg/m(2))] or CAF protocol [cyclophosphamide (600 mg/m(2)) + adriamycin (60 mg/m(2)) + 5-fluorouracil (600 mg/m(2))] for six cures were enrolled between February 2009 and June 2010. Echocardiography was performed before the onset of the chemotheurapeutic regimen (T1), on the day after the completion of the first cure (T2), and after the completion of two cures of the regimen (T3). Serum NT-proBNP levels were also measured at T1, T2, and T3. The mean right ventricular fractional area change (RVFAC) was 63.7 ± 3.63, 63.3 ± 3.67, and 61.2 ± 4.41% at T1, T2, and T3, respectively (pT1-T3 and pT2-T3 <0.05). Tricuspid annular plane systolic excursion (TAPSE) has decreased in time (1.82 ± 0.2, 1.78 ± 0.19, and 1.62 ± 0.24 cm; pT1-T2, pT1-T3, and pT2-T3 were 0.002, <0.001, and <0.001, respectively). Tricuspid annular mean E'/A' ratios were 1.42 ± 0.16, 1.36 ± 0.18, and 1.11 ± 0.32 (pT1-T2 = 0.013, pT1-T3 < 0.001, and pT2-T3 < 0.001). Mean tricuspid annular systolic velocities were 11.35 ± 1.85, 11.0 ± 1.82, and 10.45 ± 1.75 cm/s for T1, T2, and T3; and the differences between T1 and T2, T1 and T3, and T2 and T3 were all significant (P = 0.005, <0.001, and 0.001). Median serum NT-proBNP levels were 82 (60-247), 116 (60-426), and 170 (60-600) pg/mL at T1, T2, and T3. The amount of change in RVFAC and TAPSE between T1 and T3 were found to be correlated with the amount of change in NT-proBNP measurements between T1 and T3 (R: -0.7, P < 0.001; R: -0.62, P < 0.001). CONCLUSION: There is a subclinical decrease in right ventricular systolic and diastolic echocardiographic indices, although mostly, in the normal range, in a relatively short time interval after onset of chemotherapy.

Is there a relationship between obesity, heart rate variability and inflammatory parameters in heart failure?

BACKGROUND: To investigate the effect of body mass index (BMI) on heart rate variability (HRV) and inflammatory parameters in patients with heart failure. METHODS: We analyzed 55 consecutive patients (mean age, 63.5 +/- 12.8 years; male/female, 39/16) with symptomatic left ventricular systolic (ejection fraction <45%) heart failure. The participants were classified into three categories according to BMI: lean (BMI < 25 kg/m2), overweight (BMI = 25-29.9 kg/m2) and obese (BMI >or= 30 kg/m2). The cause of heart failure was mainly ischemic heart disease (75%) with mean ejection fraction 30 +/- 7%. Plasma N-terminal pro-brain natriuretic peptide (NT-proBNP) and C-reactive protein levels were measured, and time-domain HRV indices were determined on Holter electrocardiogram. The relationship between HRV indices and laboratory, inflammatory and echocardiographic parameters was investigated with correlation analysis. RESULTS: Age, sex, clinical characteristics (hypertension, diabetes mellitus, dyslipidemia, family history, smoking) were similar between groups. BMI was inversely correlated with NT-pro BNP levels (P = 0.001). HRV indices did not differ between groups. Correlation analysis demonstrated the relationship between HRV indices and fasting blood glucose (SDNN, SDANN, SDNNI, root mean square successive differences, VTI), C-reactive protein (SDANN, SDNNI, VTI), pulmonary artery pressure (SDNN, SDANN, VTI) levels. CONCLUSION: In systolic heart failure patients a higher BMI is associated with decreased NT-proBNP levels. Although HRV indices were not different between groups, inflammatory parameters, fasting blood glucose and pulmonary artery pressure were correlated with them.

The comparison of early and late outcome of direct and conventional stenting of patients with st elevation myocardial infarction.

BACKGROUND: The aim of this study was to compare direct and conventional stenting procedure in the subacute stable phase on short- and long-term results in patients with ST elevation myocardial infarction. METHODS: Eighty-eight clinically stable ST-segment elevation myocardial infarction (STEMI) patients were enrolled into the study. The patients were classified as group I (direct stenting) and group II (conventional stenting - stenting after balloon dilatation). Baseline characteristics of patients were scanned from hospital records. Coronary angiograms before and after the revascularization procedure were evaluated with the quantitative coronary angiogram technique. Patients were followed for 5 years for clinical outcomes. The study population consisted of 58 patients (65%) in group I and 30 patients (35%) in group II. Mean ages were 55.8 +/- 10.8 and 57.3 +/- 9.8, respectively. RESULTS: There were no significant differences between the two groups regarding clinical characteristics (hypertension, diabetes mellitus, family history of cardiovascular disease, smoking and dyslipidemia). The thrombus score was similar in both groups. Diameter stenosis was lower in group I (54.8 +/- 12.7 versus 61.4 +/- 12.6; p = 0.023) and TFC (Thrombolysis in Myocardial Infarction frame count) was higher in group II (30.7 +/- 14.5 versus 40.8 +/- 26.7; p = 0.02) before the percutaneous coronary intervention (PCI). Other quantitative angiographic parameters were not different. For all angiographic criteria, the difference between pre- and post-PCI parameters was significantly different in both groups. However, the change in TFC was higher within the group II compared to pre-PCI TFC rates. This difference was statistically significant (p = 0.002). Procedural success was statistically different between groups (69% in group I, 43% in group II; p50.01). Immediate clinical and angiographic results were similar. At 5-year follow-up the incidence of major adverse cardiac events including death, angina pectoris and myocardial infarction were similar for direct stenting versus conventional angioplasty. CONCLUSIONS: Direct stenting is safe and feasible for the treatment in patients with STEMI at the subacute phase. Immediate clinic, angiographic and late clinical results are similar for direct stenting and conventional stenting following balloon angioplasty. Although conventional stenting improved TFC better than direct stenting, this did not translate to better clinical outcomes.

The relationship between adiponectin levels and proinflammatory cytokines and left ventricular mass in dialysis patients.

INTRODUCTION: Adiponectin is increased in end-stage renal disease. However, efforts to clarify the cause of that increase and its clinical effects have been inconclusive. The aim of this study was to compare serum adiponectin levels of dialysis patients against healthy individuals and evaluate the relationship among adiponectin levels, IL-6, TNF- alpha and left ventricular mass index (LVMI). METHODS: Adiponectin, IL-6 and TNF- alpha measurements and echocardiographic evaluations were performed in 36 hemodialysis, 30 continuous ambulatory peritoneal dialysis (CAPD) patients and 22 healthy volunteers. Adiponectin, IL-6 and TNF- alpha levels were measured by ELISA. RESULTS: Adiponectin was found to be higher in hemodialysis (52.78+/-18.01 ng/mL) and CAPD (52.96+/-17.53 ng/mL) groups than controls (28.36+/-13.20 ng/ mL; p=0.0003, p=0.0003, respectively). No difference was observed between the hemodialysis and CAPD groups. Adiponectin was positively correlated with IL-6 (r=0.293, p=0.02), TNF- alpha (r=0.458, p=0.0003) and LVMI (r=0.283, p=0.02). In the partial correlation analysis, by controlling for body mass index, the correlation between adiponectin and TNF- alpha (r=0.466, p=0.0003) persisted. When IL-6 was controlled with TNF- alpha, the relation between adiponectin and LVMI disappeared (r=0.145, p=0.30). In the linear regression analysis, with adiponectin as the dependent variable, and IL-6, TNF- alpha and body mass index as independent variables, a significant relationship was found between adiponectin and TNF- alpha (beta=0.488, p=0.001). CONCLUSIONS: Increased adiponectin seems to be associated with increased proinflammatory cytokines in dialysis patients, and this relationship suggests adiponectin may have a role in the development of left ventricular hypertrophy.

Gemcitabine-induced acute coronary syndrome: a case report.

OBJECTIVES: To report a case of metastatic leiomyosarcoma, in which a patient developed chest pain accompanied by acute left bundle-branch block (LBBB) after gemcitabine infusion. CLINICAL PRESENTATION AND INTERVENTION: A 59-year-old woman admitted with bilateral pulmonary nodules had classic risk factors for coronary heart disease and coronary stenosis as demonstrated by previous coronary angiography. She was treated with gemcitabine infusion, and 30 min later she experienced severe chest pain accompanied by acute LBBB confirmed by ECG. We suspected gemcitabine-induced coronary vasospasm exacerbated by the preexisting coronary artery disease as the cause of the acute coronary syndrome. The patient was subsequently treated with antianginal therapy and percutaneous coronary intervention. Her chest pain resolved and LBBB disappeared. She was discharged 2 days later without any further cardiac events. No additional cancer therapy was given and she died 5 months later, due to disease progression. CONCLUSION: This case showed that chemotherapeutic agents must be administered with intensive cardiac monitoring especially in patients with cardiac disease and well-known risk factors to prevent the development of cardiac complications, despite an agent not being known to be 'cardiotoxic'.

Coronary vasospastic crisis leading to cardiogenic shock and recurrent ventricular fibrillation in a patient with long-standing asthma.

Acute myocardial infarction in patients with normal coronary arteries is a therapeutic dilemma. Coronary artery vasospasm and thrombosis are the most commonly encountered clinic problems and appear in localized coronary segments. The incidence of cardiovascular disease is increased in asthmatic patients. ß(2)-Adrenergic agonists use is associated with increased cardiovascular events. Although myocardial ischemia during asthma has been described in literature, acute myocardial infarction and ventricular fibrillation with normal coronary arteries in patients with asthma bronchiale is a rare entity. Our patient with long-standing asthma bronchiale presented with cardiogenic shock whose coronary angiography revealed multivessel disease and undergone primary percutaneous coronary intervention. Due to ongoing chest pain and hemodynamic instability; an early bypass surgery was planned. A control angiogram was performed before surgery. After intracoronary nitrate administration all narrowings in coronary vasculature disappeared. Symptom relief and clinical improvement was achieved with nitrate and calcium channel blockers later. After 2 months she was readmitted with cardiac arrest due to recurrent ventricular fibrillation and intracardiac defibrillator implantation was performed.

The relationship of visfatin levels to inflammatory cytokines and left ventricular hypertrophy in hemodialysis and continuous ambulatory peritoneal dialysis patients.

Visfatin was recently defined as an adipocytokine; however, the pathophysiological role of visfatin is not completely understood. A few studies suggest that visfatin may be a new proinflammatory adipocytokine. The aim of the present study was to compare serum visfatin levels between hemodialysis and continuous ambulatory peritoneal dialysis (CAPD) patients and evaluate the relationship between visfatin levels to IL-6, TNF-alpha, and left ventricular hypertrophy. Serum visfatin, IL-6, and TNF-alpha levels were measured by using the ELISA method, and echocardiographic evaluations were performed in 31 hemodialysis patients, 30 CAPD patients, and 21 healthy volunteers. Serum visfatin levels were higher in the CAPD group (265.27 +/- 387.86 ng/mL) than hemodialysis (97.68 +/- 244.96 ng/mL,) and control (41.33 +/- 48.87 ng/mL) groups (p = 0.04, p = 0.01, respectively). No significant difference was observed between the hemodialysis and control groups. In univariate analysis, visfatin levels were positively correlated with IL-6 (r = 0.24, p = 0.03), TNF-alpha (r = 0.34, p = 0.002), and BMI (r = 0.26, p = 0.03) and negatively correlated with some left ventricular diastolic parameters [Em and Em/Am (r = -0.305, p = 0.01), (r = -0.251, p = 0.03), respectively]. No relationship was found between visfatin and left ventricular mass index. In the linear regression analysis, visfatin levels independently related with TNF-( (beta = 0.369, p = 0.001) and IL-6 (beta = 0.284, p = 0.015). This study has found significantly higher levels of serum visfatin in CAPD patients when compared to healthy individuals. Increased visfatin levels seem to associate with proinflammatory cytokines such as IL-6 or TNF-alpha. As for the effects of on left ventricular structure and functions, visfatin might have negative effects on left ventricular diastolic function parameters but have no effects on left ventricular mass index.

Traditional risk factors are predictive on segmental localization of coronary artery disease.

The aim of this study was to investigate the relationship between established risk factors and segmental localization of coronary artery disease. A total of 2760 patients who underwent coronary angiography were enrolled into the study. Coronary angiographic segmental evaluation was performed according to the scheme of American Heart Association. Patients were classified into 2 groups (group 1: normal coronary artery segments, group 2: coronary artery segments with coronary artery disease). Smoking was highly related with left main coronary artery disease (odds ratio = 7.5; P = .005). Diabetes mellitus and male sex increased the risk of atherosclerosis in all coronary vasculature (odds ratio = 2.7-2.2; P < .001-P < .001). Hypertension was correlated with distal coronary artery (odds ratio = 1.4; P < .001) and family history with distal circumflex lesions (odds ratio = 4.5; P = .005) High triglyceride levels were associated with right coronary artery lesions (odds ratio = 1.00; P =.03). The effect of advanced age was small (odds ratio = 1.08; P < .001). Risk factors may be predictive for segmental localization.

Huge biatrial cardiac rhabdomyosarcoma resulting in bilateral atrioventricular valve obstruction.

We present a case report of a 28-year-old man with a huge tumor that occupies both dilated atria almost completely but not extending into the ventricles. Cardiac rhabdomyosarcoma (CR) is extremely rare in adult patients. Its rarity and heterogenous clinical presentation make diagnosis difficult. In our case, after we have made an initial diagnosis via echocardiography, we took biopsies under computed tomography (CT) guiding. Histologic examination showed a CR. We want to emphasize that CT-guided biopsy is a useful and applicable technique in establishing preoperative diagnosis of intracardiac masses.
