Abstract
The global incidence and prevalence of type 2 diabetes have been escalating in recent decades. Patients with type 2 diabetes have an increased risk of atherosclerotic cardiovascular disease (ASCVD). About two-thirds of death in type 2 diabetes are due to ASCVD, including 40% from coronary heart disease (CHD), 15% from heart failure (HF), and 10% from stroke. The association between hyperglycemia and elevated CV risk has been demonstrated in multiple cohort studies. However, clinical trials of intensive glucose reduction did not significantly reduce macrovascular outcomes. It remains unclear whether the absence of demonstrable benefits is attributed to the inclusion of patients with far advanced ASCVD in whom a short treatment period is barely enough for CV protective effects to be shown, or complications associated with the treatment such as hypoglycemia hamper the beneficial effects to manifest, or simply glucose-lowering per se is ineffective. Since the US FDA issued a mandate in December 2008 that every new anti-diabetic agent requires rigorous assessments of its CV safety, there have been more than 200,000 patients enrolled in a number of randomized controlled trials (RCTs), and around half of them have been completed and published. The results of these CV outcome trials are important for clinicians in their clinical practice, and also provide an opportunity for academic society to formulate treatment guidelines or consensus to provide specific recommendations for glucose control in various CV diseases. The Taiwan Society of Cardiology (TSOC) and the Diabetes Association of Republic of China (DAROC), aiming to formulate a treatment consensus in type 2 diabetic patients with CVD, have appointed a jointed consensus group for the 2018 Consensus of TSOC/DAROC (Taiwan) on the Pharmacological Management of Patients with Type 2 Diabetes and CV Diseases. The consensus is comprised of 5 major parts: 1) Treatment of diabetes in patients with hypertension, 2) Treatment of diabetes in patients with CHD, 3) Treatment of diabetes in patients with stage 3 chronic kidney disease, 4) Treatment of diabetes in patients with a history of stroke, and 5) Treatment of diabetes in patients with HF. The members of the consensus group comprehensively reviewed all the evidence, mainly RCTs, and also included meta-analyses, cohort studies, and studies using claim data. The treatment targets of HbA1c were provided. The anti-diabetic agents were ranked according to their clinical evidence. The consensus is not mandatory. The final decision may need to be individualized and based on clinicians' discretion.

Abstract
BACKGROUND The CHADS2 and CHA2 DS2 -VASc scores are clinical risk stratification instruments that are used clinically to assess the risk of stroke in patients with atrial fibrillation (AF). The aim of this study was to evaluate whether the prestroke CHADS2 and CHA2 DS2 -VASc scores could be useful for predicting infarction severity and long-term outcomes in patients with acute ischaemic stroke. MATERIALS AND METHODS This prospective study included all 1494 patients who had acute ischaemic stroke without haemorrhagic transformation which was evidenced with magnetic resonance (MR) imaging during hospitalization. Total infarction volume and arterial stenosis score were calculated based on MR imaging. National Institutes of Health Stroke Scale scores (NIHSSs) were obtained at admission and discharge by board-certified neurologists. The clinical outcomes were defined as composite endpoints of restroke and mortality and were recorded with the mean follow-up period of 37.5 months. RESULTS There were 195 (13.1%) patients with AF. The patients with AF had significantly higher median CHADS2 and CHA2 DS2 -VASc scores than the patients without AF (P < .001). Patients with higher CHADS2 and CHA2 DS2 -VASc scores had significantly higher total infarction volume, arterial stenosis score and NIHSS scores at discharge and poorer clinical outcomes. After adjusting for age, gender and AF, only CHA2 DS2 -VASc scores could predict both restroke and composite endpoints. CONCLUSIONS Prestroke CHA2 DS2 -VASc scores appear to have better clinical value for predicting the severity of infarction and long-term clinical outcomes in acute ischaemic stroke patients with and without AF.

Abstract
OBJECTIVE To identify the incidence and prehospital predictors of ventricular tachycardia/ventricular fibrillation (VT/VF) as the initial arrhythmia in patients with out-of-hospital cardiac arrest (OHCA) in central Taiwan. PATIENTS AND METHODS The Taichung Sudden Unexpected Death Registry program encompasses the Taichung metropolitan area in central Taiwan, with a population of 2.7 million and 17 destination hospitals for patients with OHCA. We performed a detailed analysis of demographic characteristics, circumstances of cardiac arrest, and emergency medical service records using the Utstein Style. RESULTS From May 1, 2013, through April 30, 2014, resuscitation was attempted in 2013 individuals with OHCA, of which 384 were excluded due to trauma and noncardiac etiologies. Of the 1629 patients with presumed cardiogenic OHCA, 7.9% (n=129) had initial shockable rhythm; this proportion increased to 18.8% (61 of 325) in the witnessed arrest subgroup. Male sex (odds ratio [OR], 2.45; 95% CI, 1.46-4.12; P<.001), age younger than 65 years (OR, 2.39, 95% CI, 1.58-3.62; P<.001), public location of arrest (OR, 4.61; 95% CI, 2.86-7.44; P<.001), and witnessed status (OR, 3.98; 95% CI, 2.62-6.05; P<.001) were independent predictors of VT/VF rhythm. CONCLUSION The proportion of patients with OHCA presenting with VT/VF was generally low in this East Asian population. Of the prehospital factors associated with VT/VF, public location of OHCA was the strongest predictor of VT/VF in this population, which may affect planning and deployment of emergency medical services in central Taiwan.

Abstract
In Taiwan, the prevalence of hyperlipidemia increased due to lifestyle and dietary habit changes. Low density lipoprotein cholesterol (LDL-C) and non-high density lipoprotein cholesterol (non-HDL-C) are all significant predicting factors of coronary artery disease in Taiwan. We recognized that lipid control is especially important in patients with existed atherosclerotic cardiovascular diseases (ASCVD), including coronary artery disease (CAD), ischemic stroke and peripheral arterial disease (PAD). Because the risk of ASCVD is high in patients with diabetes mellitus (DM), chronic kidney disease (CKD) and familial hypercholesterolemia (FH), lipid control is also necessary in these patients. Lifestyle modification is the first step to control lipid. Weight reduction, regular physical exercise and limitation of alcohol intake all reduce triglyceride (TG) levels. Lipid-lowering drugs include HMG-CoA reductase inhibitors (statins), cholesterol absorption inhibitors (ezetimibe), proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors, nicotinic acids (niacin), fibric acids derivatives (fibrates), and long-chain omega-3 fatty acids. Statin is usually the first line therapy. Combination therapy with statin and other lipid-lowering agents may be considered in some clinical settings. For patients with acute coronary syndrome (ACS) and stable CAD, LDL-C < 70 mg/dL is the major target. A lower target of LDL-C <55 mg/dL can be considered in ACS patients with DM. After treating LDL-C to target, non-HDL-C can be considered as a secondary target for patients with TG ≥ 200 mg/dL. The suggested non-HDL-C target is < 100 mg/dL in ACS and CAD patients. For patients with ischemic stroke or transient ischemic attack presumed to be of atherosclerotic origin, statin therapy is beneficial and LDL-C < 100 mg/dL is the suggested target. For patients with symptomatic carotid stenosis or intracranial arterial stenosis, in addition to antiplatelets and blood pressure control, LDL-C should be lowered to < 100 mg/dL. Statin is necessary for DM patients with CV disease and the LDL-C target is < 70 mg/dL. For diabetic patients who are ≥ 40 years of age, or who are < 40 years of age but have additional CV risk factors, the LDL-C target should be < 100 mg/dL. After achieving LDL-C target, combination of other lipid-lowering agents with statin is reasonable to attain TG < 150 mg/dL and HDL-C >40 in men and >50 mg/dL in women in DM. LDL-C increased CV risk in patients with CKD. In adults with glomerular filtration rate (GFR) < 60 mL/min/1.73m2 without chronic dialysis (CKD stage 3-5), statin therapy should be initiated if LDL-C ≥ 100 mg/dL. Ezetimibe can be added to statin to consolidate the CV protection in CKD patients. Mutations in LDL receptor, apolipoprotein B and PCSK9 genes are the common causes of FH. Diagnosis of FH usually depends on family history, clinical history of premature CAD, physical findings of xanthoma or corneal arcus and high levels of LDL-C. In addition to conventional lipid lowering therapies, adjunctive treatment with mipomersen, lomitapide, or PCSK9 inhibitors become necessary to further reduce LDL-C in patients with FH. Overall, these recommendations are to help the health care professionals in Taiwan to treat hyperlipidemia with current scientific evidences. We hope the prescription rate of lipid lowering drugs and control rate of hyperlipidemia in high risk patients could be increased by implementation of the clinical guidelines. The major purpose is to improve clinical outcomes of these high risk patients through the control of hyperlipidemia.

Abstract
Atrial fibrillation (AF) is the most common sustained arrhythmia. Both the incidence and prevalence of AF are increasing, and the burden of AF is becoming huge. Many innovative advances have emerged in the past decade for the diagnosis and management of AF, including a new scoring system for the prediction of stroke and bleeding events, the introduction of non-vitamin K antagonist oral anticoagulants and their special benefits in Asians, new rhythm- and rate-control concepts, optimal endpoints of rate control, upstream therapy, life-style modification to prevent AF recurrence, and new ablation techniques. The Taiwan Heart Rhythm Society and the Taiwan Society of Cardiology aimed to update the information and have appointed a jointed writing committee for new AF guidelines. The writing committee members comprehensively reviewed and summarized the literature, and completed the 2016 Guidelines of the Taiwan Heart Rhythm Society and the Taiwan Society of Cardiology for the Management of Atrial Fibrillation. This guideline presents the details of the updated recommendations, along with their background and rationale, focusing on data unique for Asians. The guidelines are not mandatory, and members of the writing committee fully realize that treatment of AF should be individualized. The physician's decision remains most important in AF management.

Abstract
AIMS Although dipeptidyl peptidase-4 (DPP-4) inhibitor improves glycemic control, the actual cardiovascular outcomes remain unclear. The objective of this cohort study was to thus evaluate the cardiovascular outcome in diabetic patients who received DPP-4 inhibitors (Sitagliptin). METHODS A total of 104,756 new diabetic patients were identified from the Taiwan National Health Insurance Research Database during the period from March 1, 2003 to December 31, 2011. Patients who received Sitagliptin therapy were included as exposures, and up to four age- and sex-matched controls were selected by risk-set sampling. Outcomes such as major adverse cardiovascular diseases (CVD) and deaths were assessed. Logistic regression models were applied to estimate the hazard ratios and 95 % CIs between DPP-4 inhibitor use and cardiovascular outcome. RESULTS Over a mean of 14 months, the rates of total CVD per 1000 person-months were significantly lower in Sitagliptin users (3.41 vs. 5.17, p < 0.001), whereas other different CVDs (hazard ratio [HR] 0.59; 95 % confidence interval [CI] 0.48-0.72 for coronary heart disease; HR 0.75; 95 % CI 0.59-0.96 for ischemic stroke; HR 0.86; 95 % CI 0.45-1.65 for peripheral artery occlusive disease) and all-cause mortality (HR 0.56; 95 % CI 0.41-0.74]) were also fewer after adjustment for covariates. CONCLUSIONS The results showed a favorable outcome of Sitagliptin as a class on lowering CVD incidence in patients with type 2 diabetes.

Abstract
BACKGROUND Hyperuricemia is closely linked to hypertension and may be a marker of susceptibility or an intermediate step in the development of metabolic syndrome. However, recently, there have been conflicting conclusions regarding the independent role of uric acid as a risk factor of cardiovascular disease (CVD). The specific role of serum uric acid (SUA) in relation to CVD remains controversial, and there are limited reports utilizing Asian data available on this issue. Therefore, this study investigated the association between SUA and cardiovascular disease in Taiwanese patients with essential hypertension. METHODS There were 3472 participants from 55-80 years of age (1763 males, 1709 females) from 38 sites across Taiwan in this hospital-based cross-sectional study, covering the period November 2005 to December 2006. The CVD included diagnosed angina pectoris, myocardial infarction, congestive heart failure, and stroke. RESULTS Hyperuricemia is positively associated with CVD in both sexes when a unified cut-off SUA level of 7 mg/dl was used. However, the odds ratios (ORs) for all CVD were greater in magnitude in hypertensive women than in men when there was co-morbidity of diabetes. The ORs of all CVD in the diabetes subgroup were statistically significantly (p = 0.01 for women, p = 0.07 for men). By multivariate analysis, hyperuricemia did not confer an increased risk of CVD. CONCLUSIONS Hyperuricemia may be associated with increased risk of CVD, but is not an independent risk factor of CVD in essential hypertensive Taiwanese patients.

Abstract
Molybdenum (Mo), a well-known toxic environmental and industrial pollutant, causes adverse health effects and diseases in humans and has received attention as a potential risk factor for DM. However, the roles of Mo in the mechanisms of the toxicological effects in pancreatic β-cells are mostly unclear. In this study, the results revealed dysfunction of insulin secretion and apoptosis in the pancreatic β-cell-derived RIN-m5F cells and the isolated mouse islets in response to Mo. These effects were accompanied by a mitochondria-dependent apoptotic signals including a decreased in the MMP, an increase in cytochrome c release, and the activation of caspase cascades and PARP. In addition, ER stress was triggered as indicated by several key molecules of the UPR. Furthermore, exposure to Mo induced the activation of ERK1/2, JNK, AMPKα, and GSK3-α/β. Pretreatment with specific pharmacological inhibitors (in RIN-m5F cells and isolated mouse islets) of JNK (SP600125) and AMPK (Compound C) or transfection with si-RNAs (in RIN-m5F cells) specific to JNK and AMPKα effectively prevented the Mo-induced apoptosis and related signals, but inhibitors of ERK1/2 and GSK3-α/β (PD98059 and LiCl, respectively) did not reverse the Mo-induced effects. Additionally, both the inhibitors and specific si-RNAs could suppress the Mo-induced phosphorylation of JNK and AMPKα each other. Taken together, these results suggest that Mo exerts its cytotoxicity on pancreatic β-cells by inducing dysfunction and apoptosis via interdependent JNK and AMPK activation downstream-regulated mitochondrial-dependent and ER stress-triggered apoptosis pathways.

Abstract
The aldosterone synthase gene, cytochrome P450 11B2 (CYP11B2), and mineralocorticoid receptor (MR) genes have been reported to be associated with coronary artery disease (CAD). In this study, we investigated the association of single nucleotide polymorphisms (SNPs) of CYP11B2 (CYP11B2 T-344C) and MR (MR C3514G and MR C4582A) with CAD in Taiwanese. Six hundred and nine unrelated male and female subjects who received elective coronary angiography were recruited from Chung Shan Medical University Hospital. The enrolled subjects were those who had a positive noninvasive test. CYP11B2 T-344C, MR C3514G and MR C4582A were determined by polymerase chain reaction-restriction fragment length polymorphism. We found that women with CYP11B2 C/C had a higher risk of developing CAD. However, there were no significant differences in the genotype distributions of MR C3514G and MR C4582A between the women with and without CAD. In multivariate analysis, CYP11B2 T-344C was most significantly associated with CAD in Taiwanese women. In conclusions, CYP11B2 C/C was more significantly associated with the development of CAD than diabetes mellitus or hypertension. This implies that CYP11B2 C/C plays a more important role than some conventional risk factors in the development of CAD in Taiwanese women.

Abstract
Background Epidemiological and clinical studies have clearly established the link between low-density lipoprotein cholesterol (LDL-C) and atherosclerosis-related cardiovascular consequences. Although it has been a common practice for physicians to prescribe lipid-lowering therapy for patients with dyslipidemia, the achievement rate is still not satisfied in Taiwan. Therefore, the determinants for achieving the LDL-C target needed to be clarified for better healthcare of the patients with dyslipidemia. Method This registry-type prospective observational study enrolled the patients with cardiovascular diseases (coronary artery disease (CAD) and cerebrovascular disease (CVD)) from 18 medical centers across Taiwan, and clinically followed them for five years. At every clinical visit, vital signs, clinical endpoints, adverse events, concurrent medications and laboratory specimens were obtained as thoroughly as possible. The lipid profile (total cholesterol, high-density lipoprotein cholesterol, LDL-C, triglyceride), liver enzymes, and creatinine phosphokinase were evaluated at baseline, and every year thereafter. The cross sectional observational data was analyzed for this report. Result Among the 3,486 registered patients, 54% had their LDL-C < 100 mg/dL. By univariate analysis, the patients achieving the LDL-C target were associated with older age, more male sex, taller height, lower blood pressure, more under lipid-lowering therapy, more smoking cessation, more history of CAD, DM, physical activity, but less history of CVD. The multivariate analysis showed statin therapy was the most significant independent determinant for achieving the treatment target, followed by age, history of CAD, diabetes, blood pressure, and sex. However, most patients were on regimens of very-low to low equipotent doses of statins. Conclusion Although the lipid treatment guideline adherence is improving in recent years, only 54% of the patients with cardiovascular diseases have achieved their LDL-C target in Taiwan, and the most significant determinant for this was statin therapy.

Abstract
Background The clinical EXCITE (EXperienCe of amlodIpine and valsarTan in hypErtension) study reported clinically relevant blood pressure (BP) reductions across all doses of amlodipine/valsartan (Aml/Val) and Aml/Val/hydrochlorothiazide (HCT) single-pill combinations. The study prospectively observed a multiethnic population of hypertensive patients for 26 weeks who were treated according to routine clinical practice. Here, we present the results in high-risk subgroups including the elderly, obese patients, and patients with diabetes or isolated systolic hypertension. In addition, we present a post hoc analysis as per prior antihypertensive monotherapy and dual therapy. Methods Patients prescribed Aml/Val or Aml/Val/HCT were assessed in this 26±8 week, noninterventional, multicenter study across 13 countries in the Middle East and Asia. Changes in mean sitting systolic BP, mean sitting diastolic BP, and overall safety were assessed. Results Of a total of 9,794 patients analyzed, 8,603 and 1,191 patients were prescribed Aml/Val and Aml/Val/HCT, respectively. Among these, 15.5% were elderly, 32.5% were obese, 31.3% had diabetes, and 9.8% had isolated systolic hypertension. Both Aml/Val and Aml/Val/HCT single-pill combinations, respectively, were associated with clinically relevant and significant mean sitting systolic/diastolic BP reductions across all subgroups: elderly patients (−32.2/−14.3 mmHg and −38.5/−16.5 mmHg), obese patients (−32.2/−17.9 mmHg and −38.5/−18.4 mmHg), diabetic patients (−30.3/−16.1 mmHg and −34.4/−16.6 mmHg), and patients with isolated systolic hypertension (−25.5/−4.1 mmHg and −30.2/−5.9 mmHg). Incremental BP reductions with Aml/Val or Aml/Val/HCT single-pill combinations were also observed in patients receiving prior monotherapy or dual therapy for hypertension. Overall, both Aml/Val and Aml/Val/HCT were generally well tolerated. Conclusion This large, multiethnic study supports the evidence that Aml/Val and Aml/Val/ HCT single-pill combinations are effective in diverse and clinically important subgroups of patients with hypertension.

Abstract
The principal pathogenesis of coronary artery disease (CAD) is coronary artery atherosclerosis, a chronic inflammatory disease of the vessel walls of the coronary artery. Intercellular adhesion molecule-1 (ICAM-1) displays an important role in the development of the inflammation reaction and atherosclerosis. Few studies report the association of ICAM-1 genetic polymorphisms with CAD in Taiwanese subjects. Therefore, we conducted a study to associate the single nucleotide polymorphisms (SNPs) of ICAM-1, rs5491, rs5498, rs281432 and rs3093030 with CAD. Five hundred and twenty-five male and female subjects, who received elective coronary angiography in Taiwan Chung Shan Medical University Hospital, were recruited to determine four ICAM-1 SNPs by real time-polymerase chain reaction and genotyping. The relationships among ICAM-1 SNPs, haplotypes, demographic and characteristics and CAD were analyzed. This study showed that rs281432 (C8823G) was the only ICAM-1 SNP which affect the development of CAD. Multivariate analysis revealed that ICAM-1 SNP rs281432 CC/CG [p=0.016; odds ratio (OR): 2.56, 95% confidence interval (CI): 1.19-5.56], male gender (p=0.018; OR: 1.66, 95% CI: 1.09-2.51), aspirin use in the past 7 days (p=0.001; OR: 2.05, 95% CI: 1.33-3.14), hypertension (p<0.001; OR: 2.15, 95% CI: 1.42-3.25), serum cardiac troponin I elevation (p<0.001; OR: 2.14, 95% CI: 1.47-3.24) and severe angina in recent 24 hours (p=0.001; OR: 1.97, 95% CI: 1.31- 2.95) increase the risk of CAD. In conclusion, ICAM-1 SNP rs281432 is an independent factor to predict the development of CAD. ICAM-1 SNP rs281432 homozygotic mutant GG can reduce the susceptibility to the CAD in Taiwanese subjects.

J Chin Med Assoc 2015; 78:1-47. [PMID: 25547819 DOI: 10.1016/j.jcma.2014.11.005] [Citation(s) in RCA: 139] [Impact Index Per Article: 15.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/22/2014] [Accepted: 11/11/2014] [Indexed: 11/24/2022] Open
Abstract
It has been almost 5 years since the publication of the 2010 hypertension guidelines of the Taiwan Society of Cardiology (TSOC). There is new evidence regarding the management of hypertension, including randomized controlled trials, non-randomized trials, post-hoc analyses, subgroup analyses, retrospective studies, cohort studies, and registries. More recently, the European Society of Hypertension (ESH) and the European Society of Cardiology (ESC) published joint hypertension guidelines in 2013. The panel members who were appointed to the Eighth Joint National Committee (JNC) also published the 2014 JNC report. Blood pressure (BP) targets have been changed; in particular, such targets have been loosened in high risk patients. The Executive Board members of TSOC and the Taiwan Hypertension Society (THS) aimed to review updated information about the management of hypertension to publish an updated hypertension guideline in Taiwan. We recognized that hypertension is the most important risk factor for global disease burden. Management of hypertension is especially important in Asia where the prevalence rate grows faster than other parts of the world. In most countries in East Asia, stroke surpassed coronary heart disease (CHD) in causing premature death. A diagnostic algorithm was proposed, emphasizing the importance of home BP monitoring and ambulatory BP monitoring for better detection of night time hypertension, early morning hypertension, white-coat hypertension, and masked hypertension. We disagreed with the ESH/ESH joint hypertension guidelines suggestion to loosen BP targets to <140/90 mmHg for all patients. We strongly disagree with the suggestion by the 2014 JNC report to raise the BP target to <150/90 mmHg for patients between 60-80 years of age. For patients with diabetes, CHD, chronic kidney disease who have proteinuria, and those who are receiving antithrombotic therapy for stroke prevention, we propose BP targets of <130/80 mmHg in our guidelines. BP targets are <140/90 mmHg for all other patient groups, except for patients ≥80 years of age in whom a BP target of <150/90 mmHg would be optimal. For the management of hypertension, we proposed a treatment algorithm, starting with life style modification (LSM) including S-ABCDE (Sodium restriction, Alcohol limitation, Body weight reduction, Cigarette smoke cessation, Diet adaptation, and Exercise adoption). We emphasized a low-salt strategy instead of a no-salt strategy, and that excessively aggressive sodium restriction to <2.0 gram/day may be harmful. When drug therapy is considered, a strategy called "PROCEED" was suggested (Previous experience, Risk factors, Organ damage, Contraindications or unfavorable conditions, Expert's or doctor's judgment, Expenses or cost, and Delivery and compliance issue). To predict drug effects in lowering BP, we proposed the "Rule of 10" and "Rule of 5". With a standard dose of any one of the 5 major classes of anti-hypertensive agents, one can anticipate approximately a 10-mmHg decrease in systolic BP (SBP) (Rule of 10) and a 5-mmHg decrease in diastolic BP (DBP) (Rule of 5). When doses of the same drug are doubled, there is only a 2-mmHg incremental decrease in SBP and a 1-mmHg incremental decrease in DBP. Preferably, when 2 drugs with different mechanisms are to be taken together, the decrease in BP is the sum of the decrease of the individual agents (approximately 20 mmHg in SBP and 10 mmHg in DBP). Early combination therapy, especially single-pill combination (SPC), is recommended. When patient's initial treatment cannot get BP to targeted goals, we have proposed an adjustment algorithm, "AT GOALs" (Adherence, Timing of administration, Greater doses, Other classes of drugs, Alternative combination or SPC, and LSM + Laboratory tests). Treatment of hypertension in special conditions, including treatment of resistant hypertension, hypertension in women, and perioperative management of hypertension, were also mentioned. The TSOC/THS hypertension guidelines provide the most updated information available in the management of hypertension. The guidelines are not mandatory, and members of the task force fully realize that treatment of hypertension should be individualized to address each patient's circumstances. Ultimately, the decision of the physician decision remains of the utmost importance in hypertension management.

Abstract
OBJECTIVE The EXCITE (clinical EXperienCe of amlodIpine and valsarTan in hypErtension) study was designed to evaluate the effectiveness, tolerability and adherence of amlodipine/valsartan (Aml/Val) and amlodipine/valsartan/hydrochlorothiazide (Aml/Val/HCT) single-pill combination therapies in patients with hypertension from the Middle East and Asia studied in routine clinical practice. RESEARCH DESIGN AND METHODS This was a prospective, multinational, non-interventional real-world study in which adult patients with hypertension receiving treatment with Aml/Val or Aml/Val/HCT as part of routine clinical practice were observed for a period of 26 ± 8 weeks. Dosages in milligrams (prescribed in accordance with local prescribing information) were Aml/Val: 5/80, 5/160, 10/160, 5/320 or 10/320; Aml/Val/HCT: 5/160/12.5, 10/160/12.5, 5/160/25, 10/160/25 or 10/320/25. MAIN OUTCOME MEASURES Treatment effectiveness was assessed by change from baseline in mean sitting systolic blood pressure (BP)/diastolic BP (msSBP/msDBP), and the proportion of patients achieving therapeutic goal and BP response. Safety and tolerability were also assessed. RESULTS Of 9794 patients analyzed (mean age 53.2 years), 8603 received Aml/Val and 1191 Aml/Val/HCT. At study end (26 ± 8 weeks), overall msSBP (95% confidence interval [CI]) reductions from baseline were -31.0 (-31.42, -30.67) mmHg for Aml/Val and -36.6 (-37.61, -35.50) mmHg for Aml/Val/HCT; msDBP reductions from baseline were -16.6 (-16.79, -16.34) mmHg for Aml/Val and -17.8 (-18.41, -17.22) mmHg for Aml/Val/HCT. Meaningful reductions in BP from baseline were also consistently observed across all Aml/Val dosages and severities of hypertension. Adverse events (AEs) were reported in 11.2% and 6.1% of patients in the Aml/Val and Aml/Val/HCT groups, respectively. Most frequently reported AEs in the Aml/Val and Aml/Val/HCT groups were edema and peripheral edema. While the observational design of the study has inherent limitations, it enables collection of real-world data from a more naturalistic clinical setting, and the large size of the study increases the robustness of the study, as indicated by the narrow confidence intervals for the main study outcomes. CONCLUSIONS The EXCITE study provides evidence that Aml/Val and Aml/Val/HCT provide clinically meaningful BP reductions and are well tolerated in a large multi-ethnic hypertensive population studied in routine clinical practice.

Abstract
BACKGROUND Patients with chronic kidney disease (CKD) is a very high risk cardiovascular disease population and should be treated aggressively. We investigated lipid management in CKD patients with atherosclerosis in Taiwan. METHODS 3057 patients were enrolled in a multi-center study (T-SPARCLE). Lipid goal are defined as total cholesterol (TC) < 160mg/dl, low-density lipoprotein (LDL) <100 mg/dl, high-density lipoprotein (HDL) > 40 mg/dl in men, HDL > 50 mg/dl in women, non-HDL cholesterol < 130mg/dl, and triglyceride < 150 mg/dl. RESULTS Compared with those without CKD (n=2239), patients with CKD (n=818) had more co-morbidities (hypertension, glucose intolerance, stroke and heart failure) and lower HDL but higher triglyceride levels. Overall 2168 (70.5%) patients received lipid-lowering agents. There was similar equivalent statin potency between CKD and non-CKD groups. The goal attainment is lower in HDL and TG in the CKD group as compared with non-CKD subjects (47.1 vs. 51.9% and 63.2 vs. 68.9% respectively, both p < 0.02). Analysis of sex and CKD interaction on goals attainment showed female CKD subjects had lower non-HDL and TG goals attainment compared with non-CKD males (both p < 0.019). CONCLUSION Although presenting with more comorbidities, the CKD population had suboptimal lipid goal attainment rate as compared with the non-CKD population. Further efforts may be required for better lipid control especially on the female CKD subjects.

Abstract
BACKGROUND Aldosterone is increasingly recognized for its involvement in atrial structural remodeling. However, the precise molecular mechanisms and signal pathways underlying aldosterone-induced atrial fibrosis are unknown. METHODS Western blotting was used to investigate the effects of aldosterone on the expression of mineralocorticoid receptor (MR), angiotensin II type I receptor (AT1), mitogen-activated protein kinases (MAPKs), and fibrotic marker proteins in cultured HL-1 cardiomyocytes. RESULTS Aldosterone upregulated MR and AT1 expressions in a concentration-dependent and time-dependent manner. Aldosterone (10(-6)M) significantly and time-dependently increased activation of the extracellular signal-regulated protein kinase (ERK), c-Jun N-terminal kinase (JNK), p38MAPK pathways, and the protein expression of collagen 1A and 3A (COL1A and COL3A), transforming growth factor (TGF)-β1, and α-smooth muscle actin (SMA). Pre-treatment with eplerenone (10(-10)M) prevented the increased expression of MR, MAPK signals and the above profibrotic molecules, but amplified the increase in AT1 level stimulated by aldosterone (10(-6)M). Pre-treatment with losartan (10(-10)M) or MAPK pathway inhibitors (U0126 or SP600125) abolished aldosterone-induced MR upregulation and significantly inhibited the expression of the above fibrotic marker proteins, indicating the critical role of MR and the requirement for active AT1 in the development of aldosterone-induced atrial fibrosis. CONCLUSIONS Elevated MR activity plays a central role in aldosterone-mediated activation of the MAPK signaling pathway and subsequent profibrotic effects in HL-1 atrial cells. MR/AT1 and the MAPK signaling pathway interact to trigger the molecular mechanism underlying the aldosterone-induced atrial fibrotic response. Our results support the view that MR blockade in conjunction with AT1 blockade can prevent the occurrence of atrial fibrillation.

Abstract
UNLABELLED Infective endocarditis in hypertrophic obstructive cardiomyopathy is rare. Management of this disease is challenging due to the unique features of dynamic pressure gradient over the left ventricular outflow tract and its unpredictable interaction with the management of sepsis. The added complexity of infective endocarditis further complicates an already difficult situation. A 72-year-old man with hypertrophic obstructive cardiomyopathy presented with acute stroke, fever, and Staphylococcus aureus bacteremia. Infective endocarditis of the aortic valve was confirmed. Despite treatment with antibiotics and aortic valve replacement, the patient had recurrent bacteremia and developed a periannular abscess and a subaortic-right atrial fistula, with a resulting fatal outcome. KEY WORDS Aortic valve replacement; Endocarditis; Hypertrophic obstructive cardiomyopathy; Subaortic-right atrial fistula.

Abstract
A length polymorphism of GT repeats in the promoter region of the human heme oxygenase-1 (HO-1) gene modulates its gene transcription to protect against myocardial injury. The present study investigated the association between HO-1 promoter polymorphisms and the outcomes of catheter ablation of atrial fibrillation (AF). The allelic frequencies of GT repeats in the HO-1 gene promoter were screened in 205 random individuals who underwent catheter ablation for drug refractory AF.In the patients who received catheter ablation, those with AF recurrence had fewer GT repeats (53.4±7.1 vs. 56.1±6.5, p = 0.004), a lower incidence of hyperlipidemia, more non-paroxysmal AF, and a larger left atrial diameter. After conducting a multivariate logistic analysis, the number of GT repeats (Odds ratio: 0.94, 95% CI 0.90–0.99, p = 0.01) and the diameter of the left atrium (Odds ratio: 1.08, 95% CI 1.02–1.15, p = 0.01) remained independent predictors. The carriers of GT repeats, which were <29 in both alleles, were associated with a lower sinus maintenance rate after catheter ablation (38.5% vs. 60.1%, p = 0.003). The patients were divided into paroxysmal and non-paroxysmal AF groups; the number of GT repeats was associated with AF recurrence only in the patients with paroxysmal AF. The number of GT repeats, combined with LAD, was significant for predicting AF recurrence after catheter ablation (p = 0.01). The number of GT repeats was not found to be associated with differences in the left atrial diameter, the biatrial voltage, or the levels of bilirubin, ferritin, iron, C-reactive protein, or von-Willibrand factor. In conclusions, HO-1 gene promoter polymorphisms were associated with AF recurrence after catheter ablation.

Abstract
BACKGROUND Coronary artery disease (CAD) was the second leading cause of death for the past 3 years in Taiwan. The insulin-like growth factor (IGF) system is considered a new risk factor of CAD because investigations show that the levels and bioactivity of IGF-I and IGFBP-3 (where IGFBP is insulin-like growth factor-binding protein) may be involved in elevating the risk of CAD. This study investigated the relationships among IGF-I +1770, IGF-I +6093, and IGFBP-3 -202 genetic polymorphisms and CAD in the Taiwanese population. METHODS A total of 581 subjects, including 390 non-CAD controls and 191 patients with CAD, were recruited and the isolated DNA was subjected to real-time polymerase chain to evaluate the effects of these three polymorphic variants on CAD. RESULTS Our results showed a significant association between the IGF-I +1770 gene polymorphism and increased risk of CAD. Furthermore, CAD patients with a minimum of one mutant C allele, T/C or C/C, in IGF-I +1770 gene polymorphism had significantly high blood pressure including systolic blood pressure (SBP; P = 0.025) and diastolic blood pressure (DBP; P = 0.004), compared to CAD patients with T/T homozygotes. Moreover, CAD patients with a minimum of one mutant A allele, G/A or A/A, in the IGF-I +6093 gene polymorphism had a 1.695-fold elevated risk of congestive heart failure (CHF), compared to CAD patients with the G/G homozygote. CONCLUSIONS Polymorphism of IGF-I +1770 was associated with increased CAD risk. In CAD patients, the contributions of IGF-I +1770 and +6093 could be through the effect on blood pressure in CAD patients.
