The Modification Effect of Influenza Vaccine on Prognostic Indicators for Cardiovascular Events after Acute Coronary Syndrome: Observations from an Influenza Vaccination Trial
Introduction. The prognosis of acute coronary syndrome (ACS) patients has been improved with several treatments such as antithrombotics, beta-blockers, and angiotensin-converting enzyme inhibitors (ACEI) as well as coronary revascularization. Influenza vaccination has been shown to reduce adverse outcomes in ACS, but no information exists regarding the interaction of other treatments. Methods. This study included 439 ACS patients from Phrommintikul et al. A single dose of inactivated influenza vaccine was given by intramuscular injection in the vaccination group. The cardiovascular outcomes were described as major cardiovascular events (MACEs) which included mortality, hospitalization due to ACS, and hospitalization due to heart failure (HF). The stratified and multivariable Coxâs regression analysis was performed. Results. The stratified Coxâs analysis by influenza vaccination for each cardiovascular outcome and discrimination of hazard ratios showed that beta-blockers had an interaction with influenza vaccination. Moreover, the multivariable hazard ratios disclosed that influenza vaccine is associated with a significant reduction of hospitalization due to HF in patients who received beta-blockers (HR = 0.05, 95% CI = 0.004â0.71, P=0.027), after being adjusted for prognostic indicators (sex, dyslipidemia, serum creatinine, and left ventricular ejection fraction). Conclusions. The influenza vaccine was shown to significantly modify the effect of beta-blockers in ACS patients and to reduce the hospitalization due to HF. However, further study of a larger population and benefits to HF patients should be investigated
Prospective evaluation of lipid management following acute coronary syndrome in non-Western countries
Background: Half the global burden of cardiovascular disease (CVD) is concentrated
in the Asia-Pacific (APAC) region.
Hypothesis: Suboptimal control of low-density lipoprotein cholesterol (LDL-C) may
play a large role in the burden of CVD in APAC and non-Western countries.
Methods: The Acute Coronary Syndrome Management (ACOSYM) registry is a multinational,
multicenter, prospective observational registry designed to evaluate LDL-C
control in patients within 6 months after hospitalization following an acute coronary
syndrome (ACS) event across nine countries.
Results: Overall, 1581 patients were enrolled, of whom 1567 patients met the eligibility
criteria; 80.3% of the eligible patients were men, 46.1% had ST-elevation myocardial
infarction, and 39.5% had non-ST-elevation myocardial infarction. Most
(1245; 79.5%) patients were discharged on a high-intensity statin. During the followup,
only 992 (63.3%) patients had at least one LDL-C measurement; of these, 52.9%
had persistently elevated LDL-C (>70 mg/dl). The patients not discharged on a highdose
statin were more likely (OR 3.2; 95% CI 2.1â4.8) to have an LDL-C above the
70 mg/dl LDL-C target compared with those who were discharged on a high-dose
statin.
Conclusion: Our real-world registry found that a third or more of post-ACS patients
did not have a repeat LDL-C follow-up measurement. In those with an LDL-C followup
measurement, more than half (52.9%) were not achieving a <70 mg/dl LDL-C goal,
despite a greater uptake of high-intensity statin therapy than has been observed in
recent evidence. This demonstrates the opportunity to improve post-ACS lipid management
in global community practice
Assessing and exploring the competency of prehospital emergency medical service personnel in Klang Valley, Malaysia: a mixed method approach
Introduction: The notion of competency in pre-hospital emergency medical service (EMS) personnel is mainly
focused on the professional proficiency that he/she has to provide intervention outside of hospital setting.
Consequently, the effectiveness of pre-hospital EMS performance very much depends upon the capability of
the personnel at the scene and as well during transport to the definitive care center. The aim of this study is
to appraise and explore the competency of pre-hospital care staff and provide strategies for improvement.
Methods: A mixed method approach combining the qualitative and quantitative study design. Of 134 staffs
only 111(82.84%) returned the questionnaire. Nine semi-structured interviews and two focus group discussions
were performed. The main informants were nurses/assistant medical officers, nurse/assistant medical officer
administrators, and emergency physicians. Results: From the quantitative finding on the competency of staff
handling pre-hospital EMS, all had the essential knowledge and skills. However, most of them reported not
having good knowledge and skills for invasive procedures (31%-61%), include giving medications (61%-66%).
The qualitative information provided insight about the issues and strategies for the personnel in regards to
competency. All the relevant qualitative data were merged into 5 categories relating issues and 5 categories to
strategies that could affect the competency of the personnel. Conclusion: Pre-hospital EMS systems need to
consider that the competency of pre-hospital EMS personnel has to come along with the responsible attitude
of the staff itself, the support of medical direction, clear protocol for guiding them whenever needed, and
continuous professional-development courses require them to maintain their professional proficiency.

Cost-effectiveness of pharmacist-participated warfarin therapy management in Thailand
Introduction Although pharmacist-participated warfarin therapy management (PWTM) is well established, the economic evaluation of PWTM is still lacking particularly in Asia-Pacific region. The objective of this study was to estimate the cost-effectiveness of PWTM in Thailand using local data where available. Methods A Markov model was used to compare lifetime costs and quality-adjusted life years (QALYs) accrued to patients receiving warfarin therapy through PWTM or usual care (UC). The model was populated with relevant information from both health care system and societal perspectives. Input data were obtained from literatures and database analyses. Incremental cost-effectiveness ratios (ICERs) were presented as year 2012 values. A base-case analysis was performed for patients at age 45 years old. Sensitivity analyses including one-way and probabilistic sensitivity analyses were constructed to determine the robustness of the findings. Results From societal perspective, PWTM and UC results in 39.5 and 38.7 QALY, respectively. Thus, PWTM increase QALY by 0.79, and increase costs by 92,491 THB (3,083 USD) compared with UC (ICER 116,468 THB [3,882.3 USD] per QALY gained). While, from health care system perspective, PWTM also results in 0.79 QALY, and increase costs by 92,788 THB (3,093 USD) compared with UC (ICER 116,842 THB [3,894.7 USD] per QALY gained). Thus, PWTM was cost-effective compared with usual care, assuming willingness-to-pay (WTP) of 150,000 THB/QALY. Results were sensitive to the discount rate and cost of clinic set-up. Conclusion Our finding suggests that PWTM is a cost-effective intervention. Policy-makers may consider our finding as part of information in their decision-making for implementing this strategy into healthcare benefit package. Further updates when additional data available are needed
2022 Thai Hypertension Society guidelines on home blood pressure monitoring
Abstract In 2021, the Universal Health Coverage Payment Scheme of Thailand approved home blood pressure monitoring (HBPM) devices for reimbursement. National utilization of HBPM devices will begin in 2022. This article provides the recommendations for HBPM from the Thai Hypertension Society. In this report, the authors review the benefits of HBPM and recommend confirming the diagnosis of hypertension by HBPM. Devices for HBPM should be the automated and validated upper arm cuff devices. HBPM should be ideally done for seven consecutive days before each clinic visit and take at least two readings (1 min apart) in the morning and before going to bed. The average blood pressure (BP) of 125â134/75â84 mmHg is classified as high normal BP and hypertension is BP of 135/85 mmHg or more. Target BP levels depend on the age of the patients; that is, < 125/75 mmHg for patients aged 18â65 years old, and <135/85 mmHg for patients over 65 years of age
Central hypertension is a nonânegligible cardiovascular risk factor
Abstract High blood pressure (BP) confers cardiovascular risk. However, the clinical value of central BP remains debatable. In this article, we aim to briefly review the prognosis, diagnosis, and treatment of central hypertension. Central and brachial BPs are closely correlated. In most prospective investigations, elevated central and peripheral BPs were similarly associated with adverse outcomes. Outcomeâdriven thresholds of the central systolic BP estimated by the type I device were on average 10Â mmHg lower than their brachial counterparts. Crossâclassification based on the central and brachial BPs identified that nearly 10% of patients had discrepancy in their status of central and brachial hypertension. Irrespective of the brachial BP status, central hypertension was associated with increased cardiovascular risk, highlighting the importance of central BP assessment in the management of hypertensive patients. Newer antihypertensive agents, such as reninâangiotensinâaldosterone system inhibitors and calcium channel blockers, were more efficacious than older agents in central BP reduction. Clinical trials are warranted to demonstrate whether controlling central hypertension with an optimized antihypertensive drug treatment will be beneficial beyond the control of brachial hypertension
The role of renal nerve stimulation in percutaneous renal denervation for hypertension: A miniâreview
Abstract Recent trials have demonstrated the efficacy and safety of percutaneous renal sympathetic denervation (RDN) for blood pressure (BP)âlowering in patients with uncontrolled hypertension. Nevertheless, major challenges exist, such as the wide variation of BPâlowering responses following RDN (from strong response to no response) and lack of feasible and reproducible periâprocedural predictors for patient response. Both animal and human studies have demonstrated different patterns of BP responses following renal nerve stimulation (RNS), possibly related to varied regional proportions of sympathetic and parasympathetic nerve tissues along the renal arteries. Animal studies of RNS have shown that rapid electrical stimulation of the renal arteries caused renal artery vasoconstriction and increased norepinephrine secretion with a concomitant increase in BP, and the responses were attenuated after RDN. Moreover, selective RDN at sites with strong RNSâinduced BP increases led to a more efficient BPâlowering effect. In human, when RNS was performed before and after RDN, blunted changes in RNSâinduced BP responses were noted after RDN. The systolic BP response induced by RNS before RDN and blunted systolic BP response to RNS after RDN, at the site with maximal RNSâinduced systolic BP response before RDN, both correlated with the 24âh ambulatory BP reductions 3â12 months following RDN. In summary, RNSâinduced BP changes, before and after RDN, could be used to assess the immediate effect of RDN and predict BP reductions months following RDN. More comprehensive, largeâscale and long term trials are needed to verify these findings

Insights on home blood pressure monitoring in Asia: Expert perspectives from 10 countries/regions
Abstract Hypertension is one of the most powerful modifiable risk factors for cardiovascular disease. It is usually asymptomatic and therefore essential to measure blood pressure regularly for the detection of hypertension. Home blood pressure monitoring (HBPM) is recognized as a valuable tool to monitor blood pressure and facilitate effective diagnosis of hypertension. It is useful to identify the masked or whiteâcoat hypertension. There is also increasing evidence that supports the role of HBPM in guiding antihypertensive treatment, and improving treatment compliance and hypertension control. In addition, HBPM has also shown prognostic value in predicting cardiovascular events. Despite these benefits, the use of HBPM in many parts of Asia has been reported to be low. An expert panel comprising 12 leading experts from 10 Asian countries/regions convened to share their perspectives on the realities of HBPM. This article provides an expert summary of the current status of HBPM and the key factors hindering its use. It also describes HBPMârelated initiatives in the respective countries/regions and presents strategies that could be implemented to better support the use of HBPM in the management of hypertension
Home Blood Pressure Control and Drug Prescription Patterns among Thai Hypertensives: A 1-Year Analysis of Telehealth Assisted Instrument in Home Blood Pressure Monitoring Nationwide Pilot Project
Background. Several interventions have been proposed to improve hypertension control with various outcomes. The home blood pressure (HBP) measurement is widely accepted for assessing the response to medications. However, the enhancement of blood pressure (BP) control with HBP telemonitoring technology has yet to be studied in Thailand. Objective. To evaluate the attainment of HBP control and drug prescription patterns in Thai hypertensives at one year after initiating the TeleHealth Assisted Instrument in Home Blood Pressure Monitoring (THAI HBPM) nationwide pilot project. Methods. A multicenter, prospective study enrolled treated hypertensive adults without prior regular HBPM to obtain monthly self-measured HBP using the same validated, oscillometric telemonitoring devices. The HBP reading was transferred to the clinic via a cloud-based system, so the physicians can adjust the medications at each follow-up visit on a real-life basis. Controlled HBP is defined as having HBP data at one year of follow-up within the defined target range (<135/85âmmHg). Results. A total of 1,177 patients (mean age 58âÂąâ12.3âyears, 59.4% women, 13.1% with diabetes) from 46 hospitals (81.5% primary care centers) were enrolled in the study. The mean clinic BP was 143.9âÂąâ18.1/84.3âÂąâ11.9âmmHg while the mean HBP was 134.4âÂąâ15.3/80.1âÂąâ9.4âmmHg with 609 (51.8%) patients having HBP reading <135/85âmmHg at enrollment. At one year of follow-up after implementing the HBP telemonitoring, 671 patients (57.0%) achieved HBP control. Patients with uncontrolled HBP had a higher prevalence of dyslipidemia and greater waist circumference than the controlled group. The majority of uncontrolled patients were still prescribed only one (36.0%) or two drugs (34.4%) at the end of the study. The antihypertensive drugs were not uptitrated in 136 (24%) patients with uncontrolled HBP at baseline. Calcium channel blocker was the most prescribed drug class (63.0%) followed by angiotensin-converting enzyme inhibitor (44.8%) while the thiazide-type diuretic was used in 18.9% of patients with controlled HBP and 16.4% in uncontrolled patients. Conclusion. With the implementation of HBP telemonitoring, the BP control rate based on HBP analysis was still low. This is possibly attributed to the therapeutic inertia of healthcare physicians. Calcium channel blocker was the most frequently used agent while the diuretic was underutilized. The long-term clinical benefit of overcoming therapeutic inertia alongside HBP telemonitoring needs to be validated in a future study
