Abstract
The advantage of angiotensin converting enzyme inhibitor (ACEI) and angiotensin receptor blocker (ARB) in patients with preserved LV systolic function is uncertain. We aimed to investigate the effects of ACEI/ARB in high atherosclerotic risk patients without overt heart failure (HF) on long-term major cardiovascular outcomes (MACEs). The Cohort Of patients with high Risk for cardiovascular Events (CORE-Thailand) registry is a prospective, multicenter, observational, longitudinal study of Thai patients with high atherosclerotic risk. The patients with ejection fraction < 50% were excluded. Among 8513 recruited patients, there were 4246 patients included into final analysis after propensity score matching. At 5-years follow-up, Cox regression analysis showed that ACEI/ARB was significantly associated with reduced risk of all-cause mortality or non-fatal myocardial infarction, non-fatal stroke and HF hospitalization (HR 0.82, 95% CI 0.70-0.96, P = 0.011). The benefit was driven by the reduced all-cause mortality and HF. Subgroup analysis demonstrated that ACEI/ARB decreased risk of long-term MACEs in patients with diabetes (HR 0.77, 95% CI 0.63-0.94, P = 0.011) and patients not taking statin (HR 0.57, 95% CI 0.40-0.82, P = 0.002). We demonstrated that the use of ACEI/ARB was associated with reduced risk of long-term MACEs in a large cohort of high atherosclerotic risk patients. Reduction of all-cause mortality and HF were likely the main contributors to the benefit of ACEI/ARB.

Abstract
BACKGROUND Among the rare diseases of primary cardiac tumor myxoma is a leading pathology. A sixteen-year clinical experience and follow-up ofpatients with surgical removal of this particular mass is reported. MATERIAL AND METHOD Medical records of intracardiac tumor patients between April 1995 and June 2012 were reviewed and only cardiac myxoma patients who underwent surgical resection were studied The data of clinical presentations, investigations, operative details, and results were analyzed. RESULTS Forty-five cardiac myxoma patients with a mean age of 52.6 +/- 2.3 (14 to 82) years were on operated during the sixteen-year period; of these, 76% were female. Dyspnea was the most common symptom accounting for approximately 78%,followed by heart failure 38%, and stroke 18%. Constitutional symptoms of weight loss, fatigue, and fever were found 33%, 13%, and 11%, respectively. Mean ejection fraction was 62% and the tumor size varied from 1.4 to 10 centimeters in diameter Site distribution of tumors were left atrium (89%), right atrium (9%), and multiple site (2%), with the interatrial septum as the most frequent site of attachment (69%). Patients with irregular surface tumors had 29% greater chance of having stroke than those with smooth surface tumors (p = 0.015). There was no operative or post-operative mortality. The complete follow-up was 98% with 99.8 +/- 52 months of mean follow-up. Ten and fifteen-year survival were 97%. A recurrence was found in one patient with multiple site tumors at eight-year follow-up. CONCLUSION Myxoma is a rare disease with a variety of clinical presentation. Surgical resection provides excellent operative and long-term survival. Despite a very insignificant chance of recurrence, long-term follow-up is still necessary.

Abstract
BACKGROUND The benefits of right ventricular pacing in patients with symptomatic bradycardia are well recognized. Currently, left ventricular (LV) function after cardiac pacing has already been extensively investigated. However existing data on right ventricular (RV) function in these patients is extremely limited. MATERIAL AND METHOD To test this, records of RV and tricuspid valve function of patients with a pacemaker measured at least a year after implantation were reviewed for a prevalence of RV dysfunction. The patients were also divided into those with and without RV dysfunction. Factors affecting the two groups were evaluated. RESULTS RV dysfunction and moderate to severe tricuspid valve regurgitation were found in approximately 4% and 21% respectively in cardiac pacing patients with mean implantation duration of 6.4 years. Compared to normal RV function, factors presumed to affect on RV dysfunction including site of pacing, pacing mode and percentage of ventricular pacing were not significantly different (p = 0.54, 0.37 and 0.12 respectively). CONCLUSION Based on these data, the prevalence of right ventricular dysfunction appears to be infrequent and factors that were assumed as contributors to LV dysfunction failed to show significant contributions to RV dysfunction.

Abstract
BACKGROUND Chronic right ventricular pacing has deleterious effects to left ventricular function which may be asymptomatic. Prevalence of LV dysfunction (LVEF < 50%) in RV pacing in Thai patients is not known. MATERIAL AND METHOD Patients in the Central Chest Institute of Thailand (CCIT) pacemaker clinic were retrospectively reviewed for their demographic and pacemaker data together with echocardiographic data for LV function. Analysis was done for those who were implanted for more than one year period. RESULTS Among the studied 118patients, male = 51 and female = 67, mean follow-up time 6.43 +/- 5.66 years, LV systolic dysfunction was identified in 21 (17.80%). Compared to those with no LV dysfunction, echocardiographic parameters showed larger LVsize (EDD 49.86 +/- 8.95 vs. 43.81 +/- 5.56 mm) and less thickness of the LV wall (11.05 +/- 1.60 vs. 12.49 +/- 2.79 mm). Studied clinical and pace parameters for correlation were hypertension (p = 0.048), coronary artery disease (p = 0.008), percent of ventricular pacing (p = 0.06), duration after implantation (p = 0.23), mode of pacing (p = 0.275), indication of implantation (p = 0.32, site of pacing lead (p = 0.279), moderate to severe MR (p = 0.003) and moderate to severe TR (p = 0.04). CONCLUSION LV dysfunction after pacemaker implantation was not infrequent. Parameters correlated to it were previous LV dysfunction, hypertension, coronary artery disease and increased amount of ventricular pacing. Mode of pacing and site of pacing lead were not correlated.

Abstract
AIM The impact of cardiac dysfunction on the liver is known as cardiac hepatopathy. In certain instances this can result in significant hepatic fibrosis or cirrhosis. The validity of non-invasive tools to assess hepatic fibrosis, such as FibroScan(®) which measures liver stiffness (LSM), has not been established in this setting. We examined the impact of cardiac dysfunction on LSM using FibroScan(®) and the influence of volume changes on LSM. METHODS AND RESULTS A prospective, cross-sectional study examined the use of FibroScan(®) in subjects with left-sided heart failure (LHF, n = 32), right-sided heart failure (RHF, n = 9), and acute decompensated heart failure (ADHF, n = 8). The impact of volume changes upon LSM was further examined in the ADHF group (pre- and post-diuresis) and in a haemodialysis group (HD, n = 12), pre- and post-ultrafiltration on dialysis. Compared with healthy controls [n = 55, LSM = median 4.4 (25th percentile 3.6, 75th percentile 5.1) kPa], LSM was increased in all the cardiac dysfunction subgroups [LHF, 4.7 (4.0, 8.7) kPa, P = 0.04; RHF, 9.7 (5.0, 10.8) kPa, P < 0.001; ADHF, 11.2 (6.7, 14.3) kPa, P < 0.001]. Alteration in volume status via diuresis did not change the baseline LSM in ADHF [11.2 (6.7, 14.3) to 9.5 (7.3, 21.6) kPa, P > 0.05] with mean diuresis 5051 ± 1585 mL, or ultrafiltration in HD [6.0 (3.6, 5.1) vs. 5.7 (4.8, 7.0) kPa, P > 0.05] with mean diuresis 1962 ± 233 mL. CONCLUSION Our findings support the concept of increased LSM in the cardiac failure population. LSM was not altered to a statistically significant level with acute volume changes.

Abstract
Beta-blockers (BBs) are mandatory therapy for patients with systolic chronic heart failure (CHF). However, it is uncertain whether target dose of these agents is more important than the achievement of target heart rate (HR) in maximizing the benefits of these agents. To test this, we obtained ECG absolute HR from patients with systolic CHF, together with consecutive left ventricular ejection fraction (EF) measures at least 3 months apart. Patients were divided into those who achieved target dose for beta-blocker and/or target absolute HR of < or = 60 beats per minute (bpm) and target change in HR (>10 bpm reduction) with increasing dose. Baseline ejection fraction (EF) was similar across all groups. Patients with absolute or change in HR at target achieved a greater change in EF than those not at target (P= 0.027 and P= 0.012, respectively). In contrast, those who achieved target dose did not achieve a significantly greater improvement in EF than those not at target dose (P= 0.81). Similarly for absolute EF, patients at target HR or target change in HR achieved a greater EF increase than those achieving target dose. Based on these data, target HR or change in HR appears to be more critical to improvement in EF than target dose in CHF patients. Therefore, achieving an absolute HR or change in HR with BBs may be more important than target dose in maximizing benefits of BBs in this setting.

Abstract
BACKGROUND The use of plasma levels of B-type natriuretic peptides (BNPs) to guide treatment of patients with chronic heart failure (HF) has been investigated in a number of randomized controlled trials (RCTs). However, the benefits of this treatment approach have been uncertain. We therefore performed a meta-analysis to examine the overall effect of BNP-guided drug therapy on cardiovascular outcomes in patients with chronic HF. METHODS We identified RCTs by systematic search of manuscripts, abstracts, and databases. Eligible RCTs were those that enrolled more than 20 patients and involved comparison of BNP-guided drug therapy vs usual clinical care of the patient with chronic HF in an outpatient setting. RESULTS Eight RCTs with a total of 1726 patients and with a mean duration of 16 months (range, 3-24 months) were included in the meta-analysis. Overall, there was a significantly lower risk of all-cause mortality (relative risk [RR], 0.76; 95% confidence interval [CI], 0.63-0.91; P = .003) in the BNP-guided therapy group compared with the control group. In the subgroup of patients younger than 75 years, all-cause mortality was also significantly lower in the BNP-guided group (RR, 0.52; 95% CI, 0.33-0.82; P = .005). However, there was no reduction in mortality with BNP-guided therapy in patients 75 years or older (RR, 0.94; 95% CI, 0.71-1.25; P = .70). The risk of all-cause hospitalization and survival free of any hospitalization was not significantly different between groups (RR, 0.82; 95% CI, 0.64-1.05; P = .12 and RR, 1.07; 95% CI, 0.85-1.34; P = .58, respectively). The additional percentage of patients achieving target doses of angiotensin-converting enzyme inhibitors and beta-blockers during the course of these trials averaged 21% and 22% in the BNP group and 11.7% and 12.5% in the control group, respectively. CONCLUSIONS B-type natriuretic peptide-guided therapy reduces all-cause mortality in patients with chronic HF compared with usual clinical care, especially in patients younger than 75 years. A component of this survival benefit may be due to increased use of agents proven to decrease mortality in chronic HF. However, there does not seem to be a reduction in all-cause hospitalization or an increase in survival free of hospitalization using this approach.

Abstract
OBJECTIVES To study the immediate, short, and intermediate results of transcatheter closure of secondum-type atrial septal defect using Amplatzer septal occluder devices (TCAA) in terms of clinical symptoms and residual lesions and shunts determined by transthoracic two-dimensional (TTE) and three-dimensional echocardiography (TDE). MATERIAL AND METHOD Thirty-six patients, who underwent successful TCAA at the Chest Disease Institute between August 2002 and August 2007 and were followed up clinically, by TTE and TDE at day 1-3, 4-6 months, and 1-year post TCAA, were analyzed. RESULTS TCAA was performed in 75 patients during the study period. Of these, 36 patients were completely followed-up. There were 92% female with a mean age of 40 +/- 16 yrs (range 19 to 65) and the mean of maximal size of ASD secondum determined by TTE, transesophageal echocardiography (TTE) and balloon sizing or balloon stretched diameter (BSD)was 18.9 +/- 4.7 mm (range 10-30), 22.6 +/- 5.3 mm (rang 10-32), and 24.3 +/- 5.3 mm (range 12-34) respectively. The size of ASOD was 26.4 +/- 4.9 mm (range 12-34). Fluoroscopic time was 16.4 +/- 7.1 min (range 6.7-35.6). The success rate of TCAA was 84%. No major complications and deaths were found. All of those with successful TCAA apparently improved their functional class. All of them showed complete ASD closure and yet 12 (31%) had Qp/Qs > or = 1.5 at year one. CONCLUSION TCAA is safe and effective and had resulted in clinical improvement, complete closure of secondum ASD, and good immediate, short, and intermediate outcomes with fewer complications.
