OBJECTIVES
Clinical pathways (CPs) ensure adherence to heart failure (HF) management guidelines. To optimize quality care in a low resource setting, an evidence-based care pathway for the management of acute HF was implemented at the emergency department (ED) of the Philippine General Hospital (PGH), the designated national tertiary hospital and referral center. This study aimed to describe the characteristics of adults with acute HF admitted at the ED and evaluate the quality of care they received, measured using physician adherence to the hospital’s acute heart failure CP.
METHODSThis was a retrospective, descriptive cohort study. We reviewed the inpatient charts of all adult patients with acute HF admitted to the ED of the PGH and referred to the Division of Cardiovascular Medicine between December 1, 2022 and May 31, 2023. Quality of care was assessed based on adherence to quality indicators adapted from routine and conditional order sets detailed in the pathway. Descriptive statistics was utilized to describe patient characteristics, quality of care, and outcomes.
RESULTSTwo hundred thirty-six (236) patients were included, with a mean age of 51.8 years. Majority were male (53.4%); hypertension (61.4%) and ischemic heart disease (53.8%) were the most common comorbidities, and infection the most common precipitant of decompensation (60.6%). There were optimal adherence rates to routine orders, which included referrals to Internal Medicine and Cardiology, baseline vital signs monitoring, fluid intake and output monitoring, chest radiograph, complete blood count, blood urea nitrogen, sodium, potassium, prothrombin time, partial thromboplastin time, arterial blood gas, urinalysis, and N-terminal pro b-type natriuretic peptide. Conditional orders, such as oxygen support, focused echocardiography, thyroid - stimulating hormone, and the use of vasopressors, diuretics, and venous thromboembolism prophylactic agents, were optimally performed when warranted. However, we noted suboptimal adherence to certain resource-intensive conditional orders, such as hourly monitoring of urine output (61.4%), hooking to cardiac monitor (53.8%), and performance of 12-lead ECG within 10 minutes (56.8%). Further, only 43.9% of patients were referred to the intensive care unit. Troponin I, calcium, magnesium, and albumin were ordered in excess.
CONCLUSIONOverall adherence rate of physicians to the hospital’s Acute Heart Failure Pathway was satisfactory. Work is needed to improve adherence to hourly urine output monitoring, consistent hooking to cardiac monitor, and timely performance of 12-lead ECG – an effort that begins with expanding in-hospital diagnostic equipment and human resource supply. We recommend continuous pathway implementation with periodic evaluation and stakeholder feedback to further improve quality of care.

BACKGROUND
Ischemic heart disease is the leading cause of mortality in the Philippines. Despite strong recommendations from clinical practice guidelines for reperfusion for acute myocardial infarction (AMI), local data reveal low rates of primary percutaneous coronary intervention (PCI) and early invasive strategies due to financial constraints and system inefficiencies. The recent expansion of the Philippine Health Insurance Corporation (PHIC) AMI benefits package presents an opportunity to improve access to appropriate care. A standardized, evidence-based national clinical pathway is needed to guide healthcare providers and ensure consistent, high-quality care of AMI across various healthcare settings.
OBJECTIVETo develop a standardized, evidence-based national clinical pathway for the management of AMI patients eligible under the PHIC IHD-AMI benefits package.
METHODOLOGYExisting AMI clinical pathways from nine public and private hospitals in the Philippines were collected and reviewed. A multidisciplinary Technical Working Group (TWG) appraised current guidelines using the AGREE II tool and evaluated the collected pathways to identify strengths, gaps and variations in practice. A draft pathway was created and refined through consensus-building with cardiology experts and stakeholders to develop the final pathway.
RESULTSThe final national AMI clinical pathway integrates evidence-based best practices and accounts for differences in institutional resources. It standardizes the use of ECG and cardiac biomarkers for diagnosis, provides clear criteria and timelines for reperfusion therapy, defines indications for coronary angiography and PCI, and recommends optimal medical therapy and cardiac rehabilitation.
CONCLUSIONThe national AMI clinical pathway is a critical step toward improving the quality, equity and efficiency of AMI care in the Philippines. Developed through a collaborative, evidence-based process, it aligns clinical management with international standards while addressing local healthcare system realities. Adoption by PHIC as a quality standard is expected to enhance guideline adherence, inform health policy and financing, and drive improvements in health outcomes. Continued implementation support, monitoring and evaluation are necessary to ensure its impact, particularly in under-resourced or geographically isolated settings.

BACKGROUND
Acute myocardial infarction (AMI) is the leading cause of morbidity and mortality among Filipinos. The guideline-recommended treatment for AMI includes emergency care, early electrocardiogram, emergent coronary angiogram and angioplasty, intensive care, medical management and cardiac rehabilitation. However, the cost of treatment is very high and not affordable for most Filipinos. To address this, the Philippine Health Insurance Corporation (PHIC) released the ischemic heart disease – acute myocardial infarction (IHD-AMI) Benefits Package under Circular No. 2024-0032 on December 21, 2024. This package significantly increased the insurance coverage for AMI to include invasive procedures and cardiac rehabilitation. The UP-Philippine General Hospital (UP-PGH) was the first to implement this package. This paper documents the initial planning, system changes and innovations undertaken by UP-PGH to support implementation.
METHODOLOGYThis qualitative descriptive study used retrospective document review to detail revision of the existing acute coronary syndrome (ACS) pathway and development of the AMl pathway, restructuring of patient flow and upgrades in infrastructure and hospital capabilities. Meeting minutes from the Division of Cardiovascular Medicine and UP-PGH were reviewed to describe the hospital's preparation and implementation process.
RESULTSUP-PGH established an efficient, evidence-based ACS and AMI pathway. Hospital protocols, staffing, infrastructure and equipment were aligned to implement the PHIC IHD-AMI Benefit Package. Key steps included resources upgrade, stakeholder consultations, pathway redesign, workflow development, process alignment and monitoring systems.
CONCLUSIONThe PHIC IHD-AMI Benefit Package can be successfully implemented in a tertiary hospital with catheterization laboratory. The documented process at UP-PGH can serve as a model for other institutions planning to utilize the package.

Ischemic heart disease (IHD) remains the most common cause of death while cerebrovascular disease (CVD) is the third most common in the Philippines. IHD and CVD represent complications resulting from prevalent non-communicable diseases (NCDs) and risk factors which present important opportunities for primary and secondary prevention.
This study aimed to pilot a sustainable multisectoral approach for community-based screening and management of cardiovascular (CV) risk factors and determine the effects of a multisectoral collaboration approach on the rate of screening, prevalence and control rates for selected risk factors.
This is a quality improvement project that determines the baseline prevalence and control rates of CV risk factors followed by intense screening efforts with support from private partnerships. The project's core components are: (a) capacity building (b) information dissemination; (c) service provision; and (d) health monitoring. Rates of screening, prevalence and control were monitored over a two-year period.
A total of 94,125 patients were screened through the ONE Cavite Project over two years (January 2021 to December 2022). A total of 61,271 were newly identified as having hypertension (65.1%), 24,069 diagnosed with diabetes mellitus type 2 (25.6%), 29,257 diagnosed to have dyslipidemia (31.1%) and 13,204 smokers (14.0%) were identified.
Intensification of screening was successful in improving identification of individuals with NCDs. The impact of continued educational support for both providers and patients in this study reaffirmed its role as a central component of NCD diagnosis, management and prevention.

Singapore medical journal 2025;66(4):190-194
INTRODUCTION:
Arrhythmias, especially atrial fibrillation (AF) and ventricular arrhythmias, are independent risk factors of mortality in patients with ischaemic heart disease (IHD). While there is a growing body of evidence that suggests an association between obstructive sleep apnoea (OSA) and cardiac arrhythmias, evidence on this relationship in patients with IHD has been scant and inconsistent. We hypothesised that in patients with IHD, severe OSA is associated with an increased risk of nocturnal arrhythmias.
METHODS:
We studied 103 consecutive patients with IHD who underwent an overnight polysomnography. Exposed subjects were defined as patients who had an apnoea-hypopnoea index (AHI) ≥30/h (severe OSA), and nonexposed subjects were defined as patients who had an AHI <30/h (nonsevere OSA). All electrocardiograms (ECGs) were interpreted by the Somte ECG analysis software and confirmed by a physician blinded to the presence or absence of exposure. Arrhythmias were categorised as supraventricular and ventricular. Arrhythmia subtypes (ventricular, atrial and conduction delay) were analysed as dichotomous outcomes using multiple logistic regression models.
RESULTS:
Atrial fibrillation and AF/flutter (odds ratio 13.5, 95% confidence interval 1.66-109.83; P = 0.003) were found to be more common in the severe OSA group than in the nonsevere OSA group. This association remained significant after adjustment for potential confounders. There was no significant difference in the prevalence of ventricular and conduction delay arrhythmias between the two groups.
CONCLUSION
In patients with IHD, there was a significant association between severe OSA and nocturnal AF/flutter. This underscores the need to evaluate for OSA in patients with IHD, as it may have important implications on clinical outcomes.

INTRODUCTION:
Achieving low-density lipoprotein cholesterol (LDL-C) levels is key to preventing atherosclerotic cardiovascular events. However, many high-risk cardiovascular patients still experience poor LDL-C goal attainment and receive suboptimal lipid-lowering therapy (LLT) prescriptions. Herein, we evaluated LLT prescription patterns, LDL-C goal attainment and cardiovascular mortality among this population group in Singapore.
METHODS:
This prospective observational cohort study included 555 patients with ischaemic heart disease (IHD) admitted to the hospital in 2020. The LLT prescriptions, corresponding LDL-C levels and cardiovascular outcomes were assessed over a 24-month period.
RESULTS:
Most participants were male (82.3%), with 48.5% identified as Chinese. High-intensity statin prescriptions increased from 45.4% at hospital admission to 87.1% at discharge and remained stable at approximately 80% at 6, 12, and 24 months post-discharge. Combination LLT prescriptions increased from 12.3% at discharge to 33.8% by 24 months. Ezetimibe was the most commonly prescribed second-line LLT (40.8%), followed by inclisiran (1.09%) and anti-proprotein convertase subtilisin/kexin type 9 monoclonal antibody therapies (0.87%). Over 24 months, LDL-C goal attainment rates were 22.1% for LDL-C < 1.4 mmol/L and 47.2% for LDL-C < 1.8 mmol/L. Multivariable Cox proportional hazards regression indicated that achieving LDL-C < 1.8 mmol/L goal was associated with a reduction in all-cause mortality at 24 months (hazard ratio 0.53, 95% confidence interval 0.30-0.94, P = 0.030).
CONCLUSION
Treatment gaps in lipid management persist in 80% of the study population, indicating that statin monotherapy alone is insufficient to achieve LDL-C goals. Greater efforts to improve LDL-C goal attainment rates in high-risk cardiovascular patients are imperative.

OBJECTIVE:
To observe the effects of electroacupuncture (EA) at "Shenting" (GV24) and "Baihui" (GV20) on mitochondrial autophagy in hippocampal neurons and silent information regulator sirtuin 1 (Sirt1)/forkhead box O3 (FOXO3)/PTEN-inducible kinase 1 (PINK1)/Parkin pathway in rats with learning-memory impairment after cerebral ischemia reperfusion injury.
METHODS:
A total of 35 male SD rats were randomly divided into a sham operation group (9 rats) and a modeling group (26 rats). In the modeling group, middle cerebral artery occlusion method was used to establish the middle cerebral artery ischemia-reperfusion (MCAO/R) model, and 18 rats of successful modeling were randomly divided into a model group and an EA group, 9 rats in each one. EA was applied at "Shenting" (GV24) and "Baihui" (GV20) in the EA group, 30 min a time, once a day for 14 days. After modeling and on 7th and 14th days of intervention, neurologic deficit score was observed; the learning-memory ability was detected by Morris water maze test; the morphology of neurons in CA1 area of hippocampus was detected by Nissl staining; the mitochondrial morphology was observed by transmission electron microscopy; the protein expression of Beclin-1, microtubule-associated protein 1 light chain 3B (LC3B), P62, Sitrt1, FOXO3, PINK1 and Parkin was detected by Western blot.
RESULTS:
After modeling, the neurologic deficit scores in the model group and the EA group were higher than that in the sham operation group (P<0.001); on 7th and 14th days of intervention, the neurologic deficit scores in the model group were higher than those in the sham operation group (P<0.001), the neurologic deficit scores in the EA group were lower than those in the model group (P<0.05, P<0.01). After modeling, the escape latency in the model group and the EA group was prolonged compared with that in the sham operation group (P<0.001); on 9th-13th days of intervention, the escape latency in the model group was prolonged compared with that in the sham operation group (P<0.001), the escape latency in the EA group was shortened compared with that in the model group (P<0.05, P<0.01, P<0.001). The number of crossing plateau in the model group was less than that in the sham operation group (P<0.001); the number of crossing plateau in the EA group was more than that in the model group (P<0.05). In the model group, in CA1 area of hippocampus, the number of neurons was less, with sparse arrangement, nuclear fixation, deep cytoplasmic staining, and reduction of Nissl substance; the morphology of mitochondrion was swollen, membrane structure was fragmented, and autophagic lysosomes were formed. Compared with the model group, in the EA group, in CA1 area of hippocampus, the number of neurons was increased, the number of cells of abnormal morphology was decreased, and the number of Nissl substance was increased; the morphology of mitochondrion was more intact and the number of autophagic lysosomes was increased. Compared with the sham operation group, in the model group, the protein expression of Beclin-1, FOXO3, PINK1, Parkin and the LC3BⅡ/Ⅰ ratio in hippocampus were increased (P<0.01, P<0.001), while the protein expression of P62 was decreased (P<0.05). Compared with the model group, in the EA group, the protein expression of Beclin-1, Sirt1, FOXO3, PINK1, Parkin and the LC3BⅡ/Ⅰratio in hippocampus were increased (P<0.001, P<0.01), while the protein expression of P62 was decreased (P<0.001).
CONCLUSION
EA at "Shenting" (GV24) and "Baihui" (GV20) can relieve the symptoms of neurological deficits and improve the learning-memory ability in MCAO/R rats, its mechanism may relate to the modulation of Sirt1/FOXO3/PINK1/Parkin pathway and the enhancement of mitochondrial autophagy.
