RESUMEN
BACKGROUND: The effects of glucose on cardiovascular events or mortality in nondiabetic patients has been recently reported. However, since atherosclerosis can be formed over a long period of time, it is necessary to devote several years to unveil the relationship between the two factors. Here, we attempted to find out the relationship between the mean hemoglobin A1c (HbA1c) level and HbA1c variability for 5 years and coronary artery disease (CAD) by using coronary angiography (CAG) to assess nondiabetic patients. METHODS: We reviewed patients who performed CAG who were followed up for at least 5 years after the initial diagnosis. The fasting blood test was performed annually for glucose and HbA1c level. CAD was defined as more than 50% of luminal narrowing. The severity of CAD was divided into two groups depending on whether no vessels were involved or one more vessel were involved (CAD(-) or CAD(+), respectively). RESULTS: The patients in CAD(+) group had higher mean HbA1c level for 5 years than CAD(-) group (5.71+/-0.40 vs. 5.86+/-0.68; P=0.04). Mean HbA1c was a significant predictor for CAD in multiple regression (odds ratio, 2.224; P=0.028). The percentage of patients with CAD was significantly higher in patients with >6.2% of mean HbA1c levels compared to patients with <6.2% of mean HbA1c levels (P<0.019). CONCLUSION: When the mean HbA1c levels were above 6.2%, the risk of CAD was higher. Also this study shows that HbA1c level can be one of the predictors for CAD even if the patients do not have diabetes.

BACKGROUND/AIMS: With the increasing incidence of cardiovascular disease, angiocardiography using contrast-enhancing media has become an essential diagnostic and therapeutic tool, despite the risk of contrast-medium-induced acute kidney injury (CIAKI). CIAKI may be exacerbated by renin-angiotensin-system (RAS) blockers, which are also used in a variety of cardiovascular disorders. This study evaluated the effects of RAS blockade on CIAKI after coronary angiography. METHODS: Patients who underwent coronary angiography in our hospital between May 2009 and July 2011 were reviewed. Serum creatinine levels before and after coronary angiography were recorded. CIAKI was diagnosed according to an increase in serum creatinine > 0.5 mg/dL or 25% above baseline. RESULTS: A total of 1,472 subjects were included in this study. Patients taking RAS blockers were older, had a higher baseline creatinine level, lower estimated glomerular filtration rate (eGFR), and had received a greater volume of contrast medium. After propensity score matching, no difference was observed between the RAS (+) and RAS (.) groups. Multiple logistic regression identified RAS blockade, age, severe heart failure, contrast volume used, hemoglobin level, and eGFR as predictors of CIAKI. Multiple logistic regression after propensity matching showed that RAS blockade was associated with CIAKI (odds ratio, 1.552; p = 0.026). CONCLUSIONS: This study showed that the incidence of CIAKI was increased in patients treated with RAS blockers.

We aimed comparing two-year clinical outcomes of the Everolimus-Eluting Promus and Paclitaxel-Eluting TAXUS Liberte stents used in routine clinical practice. Patients with objective evidence of ischemia and coronary artery disease eligible for PCI were prospectively randomized to everolimus-eluting stent (EES) or paclitaxel-eluting stent (PES) groups. The primary end-point was ischemia-driven target vessel revascularization (TVR) at 2 yr after intervention, and the secondary end-point was a major adverse cardiac event (MACE), such as death, myocardial infarction (MI), target lesion revascularization (TLR), TVR or stent thrombosis. A total of 850 patients with 1,039 lesions was randomized to the EES (n=425) and PES (n=425) groups. Ischemic-driven TVR at 2 yr was 3.8% in the PES and 1.2% in the EES group (P for non-inferiority=0.021). MACE rates were significantly different; 5.6% in PES and 2.5% in EES (P = 0.027). Rates of MI (0.8% in PES vs 0.2% in EES, P = 0.308), all deaths (1.5% in PES vs 1.2% in EES, P = 0.739) and stent thrombosis (0.3% in PES vs 0.7% in EES, P = 0.325) were similar. The clinical outcomes of EES are superior to PES, mainly due to a reduction in the rate of ischemia-driven TVR.

BACKGROUND: Recent studies suggested that the association of acute glucose variability and diabetic complications was not consistent, and that A1c variability representing long term glucose fluctuation may be related to coronary atherosclerosis in patients with type 1 diabetes. In this study, we attempt to determine whether or not A1c variability can predict coronary artery disease (CAD) in patients with type 2 diabetes. METHODS: We reviewed data of patients with type 2 diabetes who had undergone coronary angiography (CAG) and had been followed up with for 5 years. The intrapersonal standard deviation (SD) of serially-measured A1c levels adjusted by the different number of assessments among patients (adj-A1c-SD) was considered to be a measure of the variability of A1c. RESULTS: Among the 269 patients, 121 of them had type 2 diabetes with CAD. In patients with A1c > or =7%, the mean A1c levels and A1c levels at the time of CAG among the three groups were significantly different. The ratio of patients with CAD was the highest in the high adj-A1c-SD group and the lowest in the low adj-A1c-SD group (P=0.017). In multiple regression analysis, adj-A1c-SD was an independent predictor for CAD in subjects with A1c > or =7% (odds ratio, 2.140; P=0.036). CONCLUSION: Patients with higher A1c variability for several years showed higher mean A1c levels. A1c variability can be an independent predictor for CAD as seen in angiographs of patients with type 2 diabetes with mean A1c levels over 7%.

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.

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.

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.

BACKGROUND AND OBJECTIVES: The plasma concentration of N-terminal pro-brain natriuretic peptide (NT-pro-BNP) is a st-rong prognostic indicator for patients with heart failure (HF) across all stages of the condition. Several clinical trials have de-monstrated convincingly that neurohormonal modulation on the renin angiotensin system (RAS) decreases plasma NT-pro-BNP level and results in favorable outcomes. But there are still limited comparative data on the neuro-hormonal modulatory effects of two RAS inhibitors: angiotensin converting enzyme inhibitor and angiotensin receptor blocker. SUBJECTS AND METHODS: This study was a prospective, multi-center, randomized, open-label, controlled, and non-inferiority study involving 445 patients with left ventricular ejection fraction (LVEF) less than 45%. Patients were assigned to receive either valsartan (target dose of 160 mg bid) or enalapril (target dose of 10 mg bid) for 12 months. We compared plasma NT-pro-BNP, high sensitive C-reactive protein (hs-CRP) level and echocardiographic parameters before and after treatment with valsartan or enalapril. RESULTS: The NT-pro-BNP and hs-CRP levels were significantly decreased after 12 months of treatment with valsartan and enalapril. The percentage change was similar between both groups. LVEF improved and left ventricular internal dimensions were decreased in both groups, and there were no significant differences between two groups. CONCLUSION: Valsartan is as effective on improving plasma NT-pro-BNP level as enalapril in patients with stable chronic HF.

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.

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.

BACKGROUND/AIMS: The aims of this study were to identify real world treatment patterns of hypertension according to cardiovascular risk stratification and to evaluate blood pressure changes with anti-hypertensive treatment in each risk group. METHODS: This study included patients who were newly-diagnosed with hypertension or known hypertensive patients with uncontrolled blood pressure (BP) at seven tertiary hospitals in Busan and Ulsan. World Health Organization/International Society of Hypertension (WHO/ISH) cardiovascular risk stratification was performed through retrospective chart review. RESULTS: Angiotensin-converting enzyme inhibitors and angiotensin II receptor blockers were the most frequently prescribed drugs. The higher WHO/ISH risk group received a greater number of drugs at the initial treatment, and one year after treatment. Target BP was achieved less frequently in the higher risk group (68.2% vs. 85.2% vs. 89.0%, p < 0.001). The rate of attaining target BP was lower (50.7% vs. 81.6%, p < 0.001), and the time to attaining target BP was longer (106.5 +/- 79.2 days vs. 82.1 +/- 75.3, p = 0.001), in patients with renal disease or diabetes. Initial systolic BP above 160 mmHg (OR: 4.91, 95% CI: 2.27~10.65), renal disease (3.42, 1.60~7.32), medium or high risk group status (2.27, 1.23~4.20), initial diastolic BP above 100 mmHg (2.11, 1.11~4.04), and diabetes (2.06, 1.29~3.25) were independent factors that predicted failure of attaining the target BP. CONCLUSIONS: BP control was relatively unsatisfactory in patients with higher initial BP, renal disease, higher WHO/ISH risk group status, and diabetes. Individualized approaches for such patients are needed to improve BP control in routine clinical practice.

BACKGROUND/AIMS: Lowering low-density lipoprotein cholesterol (LDL-C) is the primary target for the prevention of cardiovascular disease. Previous studies have shown that estimated LDL-C levels calculated using Friedewald's formula (FLDL-C) are closely correlated with directly measured LDL-C levels (DLDL-C). However, because statins not only reduce LDL-C, but also alter the levels of parameters used to calculate FLDL-C (i.e., total cholesterol, triglycerides, and high-density lipoprotein cholesterol), whether calculated LDL-C levels remain a reliable estimate of actual levels after statin treatment is unclear. METHODS: Subjects included 985 patients at high risk of cardiovascular disease who had taken statins for more than 6 months. FLDL-C data were compared to DLDL-C data. RESULTS: A strong correlation was observed between DLDL-C and FLDL-C data (R2=0.879). However, the absolute values for FLDL-C and DLDL-C differed significantly according to a paired t-test, and 42.3% of patients showed a difference of greater than 10% between these two values. Among patients with diabetes, the percentage of patients deemed to have achieved target LDL-C levels differed significantly according to the method of LDL-C determination (p=0.007). CONCLUSIONS: FLDL-C and DLDL-C data remained well correlated after statin treatment, although the absolute values differed significantly according to the LDL-C determination method. Furthermore, the percentage of subjects deemed to achieve target LDL-C levels differed significantly according to the method of determination among patients with diabetes.

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.

BACKGROUND: Aberrations of cardiovascular regulation have been reported in patients who suffer with fibromyalgia (FM). Abnormalities of the cardiovascular autonomic regulation, as well as the correlation between coronary heart disease and depression, have been considered to be the causative factors. The clinical features of transient left apical ballooning syndrome with the patients under acute stress have been clearly described, but the effect of chronic stress such as FM on the myocardium is unknown. We investigated the cardiac strain in FM patients by strain imaging with using the 2D grayscale images, and we quantified the regional myocardial deformation properties. METHODS: We investigated 30 consecutive postmenopausal women (mean age: 48+/-8 years) who satisfied the criteria for fibromyalgia with atypical chest pain by performing standard and 2-dimensional strain echocardiography (2DS). Those patients with hypertension, coronary heart disease or diabetes were excluded. The global and segmental longitudinal deformation parameters of the LV from 3 apical views were analyzed, and the patients underwent a manual tender point survey for determining the number of tender points and tender point counts, and the patients completed the fibromyalgia impact questionnaire (FIQ), the brief fatigue inventory (BFI), and Beck depression inventory (BDI). RESULTS: The global longitudinal LV strain was significantly reduced in the FM patients with a high FIQ score (>40) as compared to the patients with a low FIQ score (-18.61% vs. -22.72%). Also, both the global and segmental longitudinal LV strains were negatively associated with fatigue or the tender point counts. However, there was no significant association between depression and the LV strain. CONCLUSION: This study showed the reduced myocardial longitudinal deformation in FM patients. This suggested that strain imaging is a feasible approach to assess the regional ventricular function in FM patients.

BACKGROUND AND OBJECTIVES: Several recent studies have shown that there is an inverse relationship between plasma B-type natriuretic peptide (BNP) and body mass index (BMI) in subjects with and without heart failure. Obesity frequently coexists with diabetes, so it is important to consider the relationship between diabetes and natriuretic peptide levels. We evaluated the influence of diabetes on the correlation of BNP and BMI. SUBJECTS AND METHODS: We examined 933 patients with chest pain and/or dyspnea undergoing cardiac catheterization between Feb. 2006 and Nov. 2007 in the Maryknoll cardiac center who had creatinine levels or =25 kg/m2) showed a significant negative correlation with increasing BMI (856.39+/-237.3 pg/mL, 601.69+/-159.6 pg/mL, 289.62+/-164.9 pg/mL, respectively, p<0.0001). However, in 200 diabetic patients, the correlation between BMI and NT-proBNP was not significant (r=-0.21, p=0.19), and NT-proBNP did not correlate with mitral E/Ea in obese diabetic patients (r=0.14, p=0.56). NT-proBNP was significantly correlated with mitral E/Ea in the non-obese (r=0.24, p=0.008) and non diabetic (r=0.32, p=0.003) groups. Left ventricular (LV) mass index was significantly correlated with NT-proBNP in all BMI groups (r=0.61, p<0.001), and patients with concentric cardiac hypertrophy showed the highest NT-proBNP levels. CONCLUSION: The present study demonstrates that obese patients have reduced concentrations of NT-proBNP compared to non obese patients despite having higher LV filling pressures. However, NT-proBNP is not suppressed in obese patients with diabetes. This suggests that factors other than cardiac status affect NT-proBNP concentrations.
