Relationship between Neutrophil-lymphocyte, Platelet-lymphocyte Ratio and Rheumatoid Arthritis Activity

OBJECTIVE: Although previous trials suggested a relationship between neutrophil-lymphocyte ratio (NLR), platelet-lymphocyte ratio (PLR), and systemic inflammatory response, clinical utility of NLR and PLR in rheumatoid arthritis (RA) is not well defined. This study was conducted to assess the efficiency of NLR and PLR as an inflammatory index in patients with RA. METHODS: A total of 107 patients with newly diagnosed RA who had never used steroid and a control group of 50 age- and gender-matched healthy subjects whose high sensitive C-reactive protein (hsCRP) was within normal range were included. Those with cerebrovascular diseases, diabetes, malignancies, or any cardiovascular diseases were excluded from both groups. The patients were divided into two groups according to the Disease Activity Score of 28 joints (DAS28). Group 1 included patients with a DAS28 score of 3.2 and lower (low disease activity) and group 2 included patients with a score higher than 3.2 (moderate to high disease activity). RESULTS: NLR and PLR in the patient group were 2.99±2.04, 170.90±86.49, significantly higher than that of the control group. NLR and PLR in group 2 were 4.16±2.50, 225.23±93.21, significantly higher than those of group 1 patients (2.26±1.22, 137.15±61.92). NLR and PLR both showed correlation with rheumatoid factor, hsCRP, serum albumin, Korean Heath Assesment Questionnaire, and DAS28. CONCLUSION: These data showed a positive correlation between NLR or PLR level and RA disease activity, suggesting that NLR or PLR can be used as an additional inflammatory marker in patients with RA.

Identification of a Link between Framingham Risk Score and Fracture Risk Assessment Tool / 대한내과학회지

BACKGROUND/AIMS: Although trials have suggested an association between osteoporosis and cardiovascular disease (CVD), the relationship between fracture risk and cardiovascular disease is not well defined. Here, we examined whether subjects with a higher risk of fracture also share an increased likelihood of developing CVD. METHODS: This study included 477 subjects; patients with a history of diabetes, chronic hepatopathy, nephritic syndrome, or any cardiovascular diseases were excluded. We used dual energy X-ray absorptiometry to assess the bone mineral density (BMD) of the lumbar spine and femur, and calculated fracture risk based on the Fracture Risk Assessment (FRAX) score. The Framingham risk score (FRS) was used to estimate cardiovascular risk. RESULTS: Of the 477 subjects, 222 had osteopenia and 150 had osteoporosis; the remaining 105 had a normal BMD. In men, no significant differences were observed in systolic blood pressure (SBP), diastolic blood pressure, low-density lipoprotein, high-density lipoprotein (HDL), and triglyceride (TG) between groups. Men with osteoporosis were generally older, and had significantly higher total cholesterol (TC). In women, age and FRS were significantly higher in the osteoporosis group. In the multivariate analysis, age, SBP, TC, HDL, TG, and FRAX were all significantly associated with FRS. CONCLUSIONS: These data suggest that patients with a higher risk of fracture are also at greater risk of developing CVD, indicating a possible mechanistic link between CVD and osteoporosis.

Isolated dilatation of the inferior vena cava

The diameter and collapsibility of the inferior vena cava (IVC) should be interpreted in consideration with other clinical and echocardiographic parameters before drawing definitive diagnostic conclusions. We report a case of a 46-year-old female with isolated IVC dilation and diminished inspiratory collapse without other abnormalities, and provide a brief review of the literature.

A Case of Aorta-Right Atrial Tunnel Presented with an Asymptomatic Murmur

Aorta-right atrial tunnel is a rare and distinct congenital anomaly. It is a vascular channel that originates from one of the sinuses of Valsalva with a tortuous course anterior or posterior to the ascending aorta, and terminates either in the superior vena cava or in the right atrium (RA). We report a 42-year-old female briefly with aorta-right atrial tunnel in which the left coronary artery arose from the tunnel and terminated into the RA.

Relationship between Nonalcoholic Fatty Liver Disease and Carotid Artery Atherosclerosis Beyond Metabolic Disorders in Non-Diabetic Patients

BACKGROUND: The objective of this study was to investigate the association between nonalcoholic fatty liver disease (NAFLD) and carotid artery atherosclerosis beyond metabolic disorders. METHODS: We studied 320 non-diabetic patients with ultrasonographically diagnosed NAFLD and 313 non-diabetic patients without NAFLD who have less than 40 g alcohol/week drinking history. Carotid atherosclerotic burden was assessed by carotid intima-media thickness (IMT) and plaque. All subjects were divided to the metabolic syndrome (MetS) according to International Diabetes Federation criteria. RESULTS: NAFLD patients had a significantly increased mean carotid IMT (0.79 +/- 0.18 vs. 0.73 +/- 0.13 mm; p or = 1 mm, and carotid plaque were 52.5% and 34.1% in the patients with NAFLD vs. 35.8% and 18.8% in the patients without this condition (p < 0.001). The difference in IMT and prevalence of plaque was also significant even in patients without MetS as well as those with MetS (all p < 0.05). NAFLD-associated adjusted odds ratio for increased IMT was 1.236 [95% confidence interval (CI), 1.023-1.467, p = 0.016] without MetS and 1.178 (95% CI, 1.059-1.311, p = 0.003) with MetS. NAFLD-associated adjusted odds ratio of carotid plaque was 1.583 (95% CI, 1.309-1.857, p = 0.024) without MetS and 1.536 (95% CI, 0.512-4.604, p = 0.444) with MetS. CONCLUSION: NAFLD is significantly associated with carotid atherosclerosis in non-diabetic outpatients even without MetS. Carotid screening for NAFLD might be beneficial for assessment of future atherosclerotic complications.

Perforated Mitral Valve Aneurysm in the Posterior Leaflet without Infective Endocarditis

Aneurysm of the mitral valve, although uncommon, occurs most commonly in association with infective endocarditis of the aortic valve and true mitral valve aneurysm is a rare cause of mitral regurgitation. We report a case with perforated mitral valve aneurysm in the posterior leaflet without concurrent infective endocarditis initially mistaken diagnosis of cystic mass, which was confirmed at operation with successful mitral valve annuloplasty.

Impact of Right Ventricular Apical Pacing and Its Frequency on Left Atrial Function

BACKGROUND: Right ventricular apical (RVA) pacing induces left ventricular (LV) dyssynchrony, increases the risk of persistent atrial fibrillation in the long term. The aim was to investigate the effects of RVA pacing on left atrial (LA) function, which are unknown. METHODS: Echocardiographic evaluation including LV dyssynchrony based on conventional Doppler, tissue Doppler imaging and speckle tracking strain echocardiography was done before and after (12 months) single-chamber ventricular pacemaker implantation in 40 patients with sick sinus syndrome. Patients were divided to 2 groups, according to the RVA pacing frequency (group I had higher pacing rate of more than 50% and group II, less than 50%). RESULTS: There was no significant difference in LV ejection fraction, however, mean global LV strain, myocardial performance index, and parameters of LV dyssynchrony had shown significant changes after 12 months of RVA pacing. There were also significant increase in the LA volume index and the reduction of peak systolic LA strain and strain rate (SR), peak early and late diastolic SR after RVA pacing. Moreover, there was significant deterioration of LV dyssynchrony and both LA and LV longitudinal function in even group II. LA functional deterioration and LA volume was significantly correlated with the frequency of RVA pacing. CONCLUSION: LV dyssynchrony, induced by RVA pacing, significantly impaired active LA contraction and passive stretching, and these findings were shown in the patients with even less than 50% of RVA pacing. Impairment of LA strain/SR was significantly correlated with the frequency of RVA pacing.

Hypothyroidism with Suspected Ovarian Malignancy: A Case Report / 대한내과학회지

We report a 44-year-old woman with massive ascites, elevated serum carbohydrate antigen 125 (CA 125) concentrations, pericardial effusion, and junctional bradycardia. Ascites caused by hypothyroidism are rare, and the pathogenesis is unclear. The ascitic fluid showed elevated total protein concentrations and a high serum-ascites albumin gradient. The massive ascites and increased serum, ascitic, and pericardial CA 125 concentrations led us to make an incorrect presumptive diagnosis of an ovarian malignancy with metastasis. However, there was no evidence of malignancy except the elevated CA 125 level. Similar to ascites, also junctional escape rhythm with marked bradycardia is a very rare feature of hypothyroidism. Following thyroid hormone replacement, the ascites and serum CA 125 gradually decreased, and the heart rhythm returned to sinus bradycardia. We report this case with a brief review of the literature.

Alteration of Left Ventricular Function with Dobutamine Challenge in Patients with Myocardial Bridge

BACKGROUND/AIMS: The aim of this study was to identify changes in left ventricular (LV) performance in patients with a myocardial bridge (MB) in the left anterior descending coronary artery during resting and in an inotropic state. METHODS: Myocardial strain measurement by speckle-tracking echocardiography and conventional LV wall-motion scoring was performed in 18 patients with MB (mean age, 48.1 +/- 1.7 years, eight female) during resting and intravenous dobutamine challenge (10 and 20 microg/kg/min). RESULTS: Conventional LV wall-motion scoring was normal in all patients during resting and in an inotropic state. Peak regional circumferential strain increased dose dependently upon dobutamine challenge. Longitudinal strains of the anterior and anteroseptal segments were, however, reduced at 20 microg/kg/min and showed a dyssynchronous pattern at 20 microg/kg/min. Although there were no significant differences in radial strain and displacement of all segments at rest compared with under 10 microg/kg/min challenge, radial strain and displacement of anterior segments at 20 microg/kg/min were significantly reduced compared with posterior segments at the papillary muscle level (44.8 +/- 14.9% vs. 78.4 +/- 20.1% and 5.3 +/- 2.3 mm vs. 8.5 +/- 1.8 mm, respectively; all p < 0.001), and showed plateau (40%) or biphasic (62%) patterns. CONCLUSIONS: Reduced LV strain of patients with MB after inotropic stimulation was identified. Speckle-tracking strain echocardiography identified a LV myocardial dyssynchrony that was not demonstrated by conventional echocardiography in patients with MB.

Arterial Stiffness in Female Patients With Fibromyalgia and Its Relationship to Chronic Emotional and Physical Stress

BACKGROUND AND OBJECTIVES: In patients with fibromyalgia (FM) syndrome, stress and pain may chronically enhance sympathetic activity, altering cardiovascular responses and inducing the arterial wall-stiffening process. We investigated arterial stiffness in FM patients using pulse wave velocity (PWV) and analyzed whether arterial stiffness was affected by the clinical parameters of FM. SUBJECTS AND METHODS: This study included 108 female FM patients (51.5+/-8.9 years) without any known cardiovascular diseases and 76 healthy female controls (50.1+/-8.9 years). FM patients underwent a manual tender point survey for tender point counts, and completed the visual analogue scale (VAS) of pain and fibromyalgia impact questionnaire (FIQ), which were composed of a physical and feel score. Brachial-ankle pulse-wave velocity (baPWV) was measured with an automated device. The study participants were subdivided into 2 groups based on the sum of the FIQ score (group A: FIQ > or =50, group B: <50). RESULTS: Patients with FM had significantly higher baPWV than the controls, and significant increase were noted in baPWV values of group A compared with those of group B. BaPWV showed a significant positive correlation (correlation coefficient=6.83, p=0.022) with severity of disease assessed by FIQ. CONCLUSION: The patients with FM showed significantly increased arterial stiffness, suggesting a pathophysiologic link between FM and endothelial dysfunction. This study provides a basis for clarifying the mechanism by which chronic pain syndrome is associated with an increased risk of vascular stiffness.

Dual Fistulas of Ascending Aorta and Coronary Artery to Pulmonary Artery

Coronary artery fistula to pulmonary artery is common. However, to the best of our knowledge, a case of coronary artery fistula to pulmonary artery associated with aortopulmonary fistula remains unreported. We herein report a 64-year-old female with a left anterior descending coronary artery and ascending aorta to pulmonary artery fistulas, and conduct a brief review of the literature.

A Rare Case with Primary Undifferentiated Carcinoma of Pericardium

A primary pericardial tumor is very rare. A 77-year-old woman was admitted to our hospital with chief complaint of exertional dyspnea due to large amount of pericardial effusion. She was finally diagnosed as pericardial undifferentiated carcinoma without definite histopathologial, immunochemistry feature. Despite palliative radiation therapy, the patient died of multiple organ failure. The prognosis of primary pericardial undifferentiated carcinoma is known to be very poor, especially in old people.

Assessment of Myocardial Function in Patients With Fibromyalgia and the Relationship to Chronic Emotional and Physical Stress

BACKGROUND AND OBJECTIVES: An association between emotional or physical stressful triggers and adverse cardiovascular events, such as death and myocardial infarction, has been recognized for many years. The clinical features of transient left apical ballooning syndrome have been clearly described, but the effect of chronic stress on the myocardium is unknown. Our objective was to assess left ventricular (LV) function in patients with fibromyalgia (FM) with chronic emotional and physical stress. SUBJECTS AND METHODS: We investigated 30 consecutive postmenopausal women (mean age, 48+/-8 years) satisfying the criteria for FM with atypical chest pain and 20 age-matched healthy controls by means of standard and 2-dimensional strain (2DS) echocardiography. Patients with hypertension, coronary heart disease, or diabetes were excluded. Global and segmental longitudinal deformation parameters of LV function from 3 apical views were analyzed, and patients underwent a manual tender point survey for the number of tender points and tender point counts, and completed the Fibromyalgia Impact Questionnaire (FIQ), which was comprised of physical and feel scores, the Brief Fatigue Inventory (BFI), and the Beck Depression Inventory (BDI). RESULTS: Both global and segmental longitudinal LV strains were significantly reduced in FM patients with high FIQ scores (>50) compared to FM patients with low FIQ scores (-18.98% vs. -22.72%). Various emotional and physical stress indexes were significantly correlated with global LV strain. CONCLUSION: Global and segmental LV strains were negatively associated with fatigue, tender point count, and FIQ score. However, there was no significant association between depression and LV strain. This study demonstrated that chronic emotional or physical stress in FM patients might reduce myocardial longitudinal deformation.

Comparison of Triple Anti-Platelet Therapy (Aspirin, Clopidogrel, and Cilostazol) and Double Anti-Platelet Therapy (Aspirin and Clopidogrel) on Platelet Aggregation in Type 2 Diabetic Patients Undergoing Drug-Eluting Stent Implantation

BACKGROUND AND OBJECTIVES: Triple anti-platelet therapy may produce more potent inhibition of platelet aggregation in patients undergoing coronary stent implantation. We tested whether this effect could be maintained in diabetic patients, where platelet reactivity is increased and the risk of stent thrombosis is higher. SUBJECTS AND METHODS: Fifty five type 2 diabetic patients who had undergone drug-eluting stent (DES) implantation and chronic anti-platelet therapy (>1 month) were stratified according to the status of anti-platelet therapy. Platelet aggregation after adenosine diphosphate (ADP; 10 micronmol/L and 20 micronmol/L) stimulation was compared using light transmittance aggregometry between dual (aspirin plus clopidogrel, n=34) and triple therapy (aspirin, clopidogrel plus cilostazol, n=21) groups. RESULTS: The 2 groups had similar clinical and procedural characteristics. Maximal ADP-induced platelet aggregation was significantly lower in the triple therapy group than the dual therapy group (ADP 10 micronmol/L, 37.1+/-15.4 vs. 28.3+/-11.8, p=0.03; ADP 20 micronmol/L, 63.1+/-15.0 vs. 49.1+/-15.1, p=0.01), but there were no differences in diabetic treatment (oral hypoglycemic agent vs. insulin) or diabetic control {hemoglobin Alc (HbA1c)7}. CONCLUSION: Triple anti-platelet therapy showed more potent inhibition of maximal ADP induced platelet aggregation in type 2 diabetic patients receiving chronic anti-platelet therapy. This finding suggests that triple antiplatelet therapy may be more effective in preventing thrombotic complications after DES implantation in type 2 diabetic patients.

Association of P-Wave Dispersion With Paroxysmal Atrial Fibrillation in Patients With Acute Anterior Wall ST Segment Elevation Myocardial Infarction

BACKGROUND AND OBJECTIVES: P-wave dispersion (PWD) is a well-known electrophysiologic parameter of atria which are prone to fibrillation. Although paroxysmal atrial fibrillation (PAF) following an acute myocardial infarction (AMI) is not uncommon, the relationship between PWD and PAF following AMI has not been determined. SUBJECTS AND METHODS: We reviewed the electrocardiograms, recorded on admission and every day during hospitalization, of 144 patients with primary anterior AMIs and measured the P-wave duration. The left atrial diameter and left ventricular ejection fraction (LVEF) were evaluated by echocardiography. RESULTS: PAF occurred in 20 patients. The maximum P-wave duration and PWD were found to be significantly higher in patients with PAF than those without PAF (120.1+/-8.6 vs. 109.2+/-12.2 ms, p<0.001; and 68.5+/-11.9 vs. 48.7+/-9.6 ms, p<0.001, respectively). The minimum P-wave duration was significantly lower in patients with PAF than in patients without PAF (51.6+/-13.3 vs. 60.4+/-11.7 ms, respectively, p=0.003). There was no significant difference in the left atrial diameter between patients with PAF and patients without PAF (37.3+/-4.4 vs. 36.8+/-5.1 mm, respectively p=0.652); however, the LVEF was significantly different in the patients who developed PAF compared to those who did not develop PAF (38.5+/-11.4 vs. 45.1+/-8.7%, respectively, p=0.003). CONCLUSION: The maximum P-wave duration and PWD were significant predictive factors of PAF in patients with anterior wall ST elevation AMI based on univariate analysis. On the basis of multivariate analysis, age was an independent predictive parameter for PAF as well.

A Case with Patent Ductus Arteriosus Complicated by Pulmonary Artery Endarteritis

Infective endarteritis in the pulmonary artery is unusual. However, congenital heart disease such as patent ductus arteriosus (PDA) could be a predisposing factor of infective endarteritis. We report a patient with PDA complicated by infective endarteritis and large pulmonary artery vegetation. After three weeks of antibiotic treatment, the patient underwent surgical closure of the PDA and removal of the vegetation.

Impact of ST segment deviation in patients with acute myocardial infarction and left ventricular systolic dysfunction / 대한내과학회지

BACKGROUND/AIMS: Although the impact of ST segment elevation in patients with acute myocardial infarction (MI) has been studied, little information is available on the impact of ST segment elevation in the patients with acute MI and left ventricular systolic dysfunction. METHODS: We retrospectively analyzed the baseline clinical and angiographic characteristics and the in-hospital and 1- year clinical outcomes of 117 consecutive patients who were diagnosed with acute MI and who had a left ventricular ejection fraction of less than 40%, and these patients were treated from January 2004 to June 2006 at Busan Paik Hospital. Coronary angiography at the index hospitalization and the major adverse cardiac events (MACEs), including cardiac death, non-fatal reinfarction, target vessel revascularization (TVR), and heart failure, were compared between the 77 patients with ST segment elevation myocardial infarction (STEMI) and the 40 patients with non-ST segment elevation myocardial infarction (NSTEMI). RESULTS: Overall, the baseline clinical characteristics were similar between the two groups. On the coronary angiography, thrombolysis in myocardial infarction 0 flow was more common in the STEMI group as compared to the NSTEMI group (p<0.01) and the NSTEMI group had more frequent multivessel disease compared to the STEMI group (p=0.01). However, the in-hospital cardiac deaths and MACEs were not different on comparison between the two groups (p=0.66, p=0.81, respectively). The one-year cardiac deaths and MACEs were not significantly different on comparison between the two groups (p=0.37, p=0.68, respectively). CONCLUSIONS: This study demonstrated that ST segment elevation had no influence on in-hospital and the long term outcomes of patients with acute MI and left ventricular systolic dysfunction.

Huge Aneurysm of the Sinus of Valsalva Compressing the Left Atrium

Sinus of Valsalva aneurysms are rare cardiac anomalies. They can be congenital or acquired, and mainly involve the right or non-coronary sinuses. Unruptured aneurysms are usually asymptomatic unless they compress other structures or produce thrombi. A sinus of Valsalva aneurysm can also produce myocardial infarction through thrombus formation secondary to the turbulent flow in the Valsalva aneurysm. We report a case of a huge sinus of Valsalva aneurysm involving the noncoronary sinus, which was diagnosed as the presumed source of acute myocardial infarction.

Coronary artery fistula associated with single coronary artery / 소아과

A case of a single coronary artery complicated with a coronary artery fistula (CAF) to the right ventricle is extremely rare, and its management strategy and prognosis are not clear. A 5-year-old boy was hospitalized for evaluation of a continuous heart murmur. Transthoracic echocardiography suggested a CAF to the right ventricle, with an enlarged left coronary artery. Cardiac catheterization confirmed the CAF terminating at the right ventricle and the absence of a right coronary artery. The fistula was ligated at the right ventricular side under cardiopulmonary bypass. At follow-up 18 months later, the child was clinically asymptomatic, and coronary angiogram showed no recurrence of the fistula.
