INTRODUCTION: Randomised controlled trials (RCTs) have informed guideline recommendations for the management of stable coronary artery disease (CAD). However, the real-world impact of contemporary guidelines and trials on practising physicians in the Asia-Pacific region remains uncertain. We aimed to evaluate the knowledge, attitudes and practices among cardiovascular physicians in the region regarding stable CAD management. METHOD: An anonymised cross-sectional electronic survey was administered to cardiovascular practitioners from the Asia Pacific, assessing 3 domains: 1) baseline knowledge on recent trials and society guideline, 2) attitudes towards stable CAD, and 3) case scenarios reflecting management preferences. Correlations among knowledge, attitudes and practice scores were assessed between physicians from developed and developing countries using Pearson correlation. RESULTS: Overall, 713 respondents from 21 countries completed the survey. The mean knowledge score was 2.90±1.18 (out of 4), with 37.3% of respondents answering all questions correctly, while 74.6% noted that guidelines have significant impact on their practice. Despite guidelines recommending optimal medical therapy, majority chose revascularisation (range 53.4- 90.6%) as the preferred strategy for the case scenarios. Practitioners from developed regions had higher knowledge scores and lower attitude scores compared to developing regions, while practice scores were similar in both groups. Weakly positive correlations were noted between knowledge, attitude and practice scores. CONCLUSION Variations exist in knowledge and attitudes towards guideline recommendations and correspondingly actual clinical practice in the Asia Pacific, with most practitioners choosing an upfront invasive strategy for the treatment of stable CAD. These differences reflect real-world disparities in guideline interpretation and clinical adoption.

INTRODUCTION

Heart failure (HF) is a common cause of hospitalization, heart failure-related readmission, poor quality of life, and mortality. It also poses a substantial economic burden. The heart failure clinical practice guideline (HFCPG) was developed to provide evidence-based recommendations on the diagnosis and management of chronic HF with reduced ejection fraction (HFrEF) among adult Filipino patients in the outpatient setting for primary care physicians.

The GRADE approach and an Evidence-to-Decision framework were used to evaluate the evidence and formulate recommendations. The strength and direction of each recommendation were determined through voting, with consensus reached if 75% of all CP members agreed.

The HFCPG provides 19 recommendations and one good practice statement in response to 14 identified clinical questions. Careful history-taking and physical examination, use of chest x-ray to detect cardiomegaly and/or pulmonary congestion, two-dimensional echocardiography for HF diagnosis, and baseline determination of serum sodium, potassium, and creatinine to guide management have been highly recommended; however, the 12-lead electrocardiogram should not be solely used for HF diagnosis. Judicious use of diuretics to relieve congestion, use of selected beta-blockers, renin-angiotensin-aldosterone blockers, mineralocorticoid receptor antagonists, and SGLT2 inhibitors are strongly recommended for the treatment of HFrEF.

HFrEF is a complex condition that requires early recognition and careful management. Guideline-directed medical therapies, particularly the evidence-based pillars of treatment, are recommended, as well as early discussion of palliative care, timely determination of advanced heart failure and the need for referral to higher levels of care.

INTRODUCTION

Sinus of Valsalva aneurysms (SOVA) are rare conditions in which a portion of the aortic root dilates due to weakness of the aortic wall, which can eventually lead to rupture, leading to a shunt from the aorta into any one of the cardiac chambers. Some patients can present asymptomatically and are diagnosed incidentally, while others can present with precipitous courses with symptoms of chest pain, palpitations and heart failure. When left untreated, these patients have poor prognosis.

A total of six patients are presented in this case series. These patients were seen in a national tertiary hospital from 2018 to 2024. The patients had varied characteristics, with ages ranging from 24-57 years old. Most of the patients were males. The presenting symptoms are also varied, with dyspnea being the most common symptom and a murmur being the most common sign. The most commonly involved sinus was the right coronary sinus draining into the right ventricle, with half of the patients presenting with concomitant ventricular septal defects. Five out of the six patients underwent successful open repair of their ruptured SOVAs and were eventually discharged.

Early identification of the cardiac lesion is important to clinch the diagnosis and plan for eventual definitive management. Imaging studies such as transthoracic echocardiogram are needed to visualize the defect, which is classically described as a windsock deformity. Transesophageal echocardiography may present clearer images to assess the anatomy better preoperatively. Medical management is usually done to bridge the patient to more definitive therapy, either through endovascular closure if the anatomy permits it or through surgical repair. Urgent and timely repair is needed to ensure improved survival in these patients.

The assessment of mitral valve anatomy can be difficult or even misleading on standard cardiac imaging procedures. Such is the scenario in a 40-year-old woman with an incidental finding of atrial septal defect (ASD) and consideration of a trileaflet versus double-orifice mitral valve (DOMV) on transthoracic two-dimensional echocardiography. Further interrogation using transesophageal two dimensional and transthoracic three-dimensional (3D) echocardiography (to allow more accurate assessment and simultaneous viewing of multiple imaging planes) revealed the typical “seagull wing” configuration of the mitral valve on long-axis view and two distinct but nearly equal-sized orifices on short-axis view, one oriented anteriorly and the other posteriorly. The patient’s DOMV was classified as an incomplete bridge type as confirmed on 3D imaging, with each orifice having its own set of papillary muscles and chordal attachments. The mitral regurgitation was graded as severe, resulting from leaflet prolapse of the anterior orifice. No left ventricular outflow tract obstruction was demonstrated in this case, and the overall left ventricular systolic function was preserved. The ASD was of the primum type, with the configuration and exact location verified through 3D imaging. The accurate detection of congenital anomalies via noninvasive techniques and complementary advanced modalities is vital for preoperative planning, as well as anticipation of potential complications related to the structural anomalies. To our knowledge, this is the first local report of DOMV with primum ASD in an adult.

INTRODUCTION: Maldistribution of echocardiographic expertise is a relevant issue in an archipelago such as the Philippines. We specifically looked at (1) the nationwide census of physician echocardiographers, cardiac sonographers, and cardiac laboratory managers; (2) their geographic distribution; and (3) background training and laboratory classification. METHODS: Data from paper and online surveys conducted in 2015 and 2021 were consolidated alongside the existing society database. Surveys (Google Forms; Google, Mountain View, California) were disseminated through a variety of online, social media, and communication avenues and focused on three categories of respondents: (1) physician echocardiographers, (2) cardiac sonographers, and (3) laboratory managers. The main variables of interest included estimated census per category and geographical distribution. Secondary variables included training background and laboratory classification. RESULTS: In 2021, there were 651 physician echocardiographers, 2487 cardiac sonographers, and 443 cardiac laboratory managers on record, with86 readers, 405 sonographers, and 101 managers responding to the survey. The majority of the surveyed readers (41.2%), sonographers (48.3%), and laboratory managers (28.2%) were situated in the National Capital Region. Close to half of the readers were level III echocardiographers. The majority of the sonographers (46.7%) were nurses, followed by medical technologists (21.8%) and radiologic technologists (18.9%).Most laboratory managers were in nontraining hospitals (38.2%) or stand-alone facilities (20.9%). The minority were in hospitals with cardiology (18.2%) or internal medicine (22.7%) training programs. CONCLUSION Geographical maldistribution of echocardiographic resources is still evident, with the majority of human resources being concentrated in the metropolis. The majority of the sonographers have nursing as their training background, and many laboratory managers are situated in facilities with no established training programs.

Objective. Several studies showed that genetic factors affect responsiveness to statins among different populations. This study investigated the associations of candidate genetic variants with poor response to statins among Filipinos.

Methods. In this unmatched case-control study, dyslipidemic participants were grouped into statin responders and poor responders based on the degree of reduction in LDL-c from baseline. DNA from blood samples were genotyped and analyzed. The association of candidate variants with statin response was determined using chi-square and logistic regression analysis.

Results. We included 162 adults on statins (30 poor responders as cases, 132 good responders as controls). The following variants are nominally associated with poor response to statin among Filipinos at a per-comparison error rate of 0.05: rs173539 near CETP (OR=3.05, p=0.015), rs1800591 in MTTP (OR=3.07, p=0.021), and rs1558861 near the BUD13-ZPR1-APOA5 region (OR=5.08, p=0.004).

Conclusion. Genetic variants near CETP, MTTP and the BUD13-ZPR1-APOA5 region are associated with poor response to statins among Filipinos. Further study is recommended to test the external validity of the study in the general Filipino population.

Background. Low levels of high-density lipoprotein cholesterol (HDL-c) is a well-recognized risk factor in the development of cardiovascular diseases. Associated gene variants for low HDL-c have already been demonstrated in various populations. Such associations have yet to be established among Filipinos who reportedly have a much higher prevalence of low HDL-c levels compared to other races.

Objective. To determine the association of selected genetic variants and clinical factors with low HDL-c phenotype in Filipinos.

Methods. An age- and sex-matched case-control study was conducted among adult Filipino participants with serum HDL-c concentration less than 35 mg/dL (n=61) and those with HDL-c levels of more than 40 mg/dL (n=116). Genotyping was done using DNA obtained from blood samples. Candidate variants were correlated with the low HDL-c phenotype using chi-squared test and conditional logistic regression analysis.

Results. Twelve single nucleotide polymorphisms (SNPs) were associated with low HDL-c phenotype among Filipinos with univariate regression analysis. The variant rs1260326 of glucokinase regulator (GCKR) (CT genotype: adjusted OR=5.17; p-value=0.007; TT genotype: adjusted OR=6.28; p-value=0.027) remained associated with low HDL-c phenotype, together with hypertension and elevated body mass index, after multiple regression analysis.

Conclusion. The variant rs1260326 near GCKR is associated with low HDL-c phenotype among Filipinos. Its role in the expression of low HDL-c phenotype should be further investigated prior to the development of possible clinical applications.

BACKGROUND

The COVID-19 pandemic greatly affected training programs because of changes in patient load and service assignments. This posed certain challenges in the implementation of the pre-COVID-19 training curriculum recommendations by the Philippine Heart Association Specialty Board on Adult Cardiology.

This article describes the challenges, training adjustments and innovations, and the impact on the training program of these changes instituted by the University of the Philippines-Philippine General Hospital (UP-PGH) Division of Cardiovascular Medicine (DCVM) during the COVID-19 pandemic.

This is a descriptive article based on review of changes and improvements of the UP-PGH DCVM training manual and guidelines adopted during the COVID-19 pandemic.

The COVID-19 pandemic challenges provided opportunities for innovation of the training program. The program emphasized focus on maximizing team-based learning from every clinical encounter toward achievement of learning outcomes and competency. The training committee closely monitored the learning environment and trainee's learning progress to achieve outcomes beyond the traditional metrics such as census and procedural numbers. It adopted online clinical encounters, conference, and case discussion. To enhance learning, virtual engagement supplemented physical encounters between consultants and training fellows assigned to various clinical rotations. Real-world research results on the impact of COVID-19 on cardiovascular health were utilized to enhance knowledge. Risk mitigation and transmission reduction strategies were adopted to ensure safety of all staff. The division also incorporated a strong wellness program to provide holistic approach to trainees' and trainers' health. New competencies were developed such as telemedicine, infection prevention and control, and creation of virtual patient education programs.

The training institution met the challenges posed by the COVID-19 pandemic with resiliency and unity. The adjustments and innovations in training instituted by PGH DCVM proved useful in addressing the challenges posed by the pandemic. The situation was viewed as an opportunity to innovate and pursue a better program adaptive of the ever-changing environment, toward forming competent future cardiologists by enhancing focus not only on numbers but rather on the process of achievement of learning outcomes, embracing virtual and online strategies, institutionalization of wellness program, and development of new guidelines in the approaching patient management cognizant of both health care provider and patient safety and new competencies such as patient virtual education and telemedicine in cardiology.

Background. Despite the recent advances in advanced cardiac life support (ACLS), there has been no significant improvement in survival among patients who undergo cardiac arrest. To date, there are no local guidelines on the requirements or standards of in-hospital cardiac arrest teams in the Philippines. In addition, there are still no studies on the outcomes of cardiac arrests among adult patients in a tertiary hospital in the Philippines. Objectives. The objective of this study is to investigate patient-, event-, and hospital-related factors associated with survival among adult patients who underwent in-hospital cardiac arrest in the service wards and intensive care units of a tertiary hospital. Methods. This is a prospective cross-sectional study conducted over three months in 2018. Patient-, event- and hospital-related data were collected from each patient with a cardiac arrest event who was referred to the cardiac arrest teams based on the modified Utstein form of reporting cardiac arrests. Survival to discharge from cardiac arrest was the main outcome. Results. The study included 119 patients, 47.9% male, with a mean age of 50.1 years (SD 16.7). Survival rate was 6.7%. The mean response time did not differ between survival group (1.46 minutes) and mortality group (1.82 minutes) (p value = 0.26). The presence of a shockable initial rhythm (3.6% vs 3/8; p value = 0.01), shorter lag time to initiation of electrical therapy (6.0 vs 9.3 ± 5.6 min; p value = 0.02), shorter time to establishment of an airway (2.75 ± 1.6 vs. 6.98 ± 5.2 min; p value = 0.01), and shorter duration of resuscitation (7 ± 4.6 vs. 13.0 ± 7.9 min; p value = 0.01) were significantly associated with survival. The presence of underlying illnesses is associated with higher mortality. The most common hospital-related problems identified were the need to cover long distances, delay in the call, and the lack of elevators. Conclusion. The survival rate of patients who underwent cardiac arrest and resuscitation by a cardiac arrest team is low. The initial presenting rhythm, lag time to initiation of electrical therapy, time to establishment of airway, duration of resuscitation, as well as the underlying disease can significantly affect survival. Streamlining the resources of the hospital to address these matters can have an impact on survival.

Introduction: Myocarditis is a rare but serious complication of systemic lupus erythematosus (SLE). Existing literature on adult Filipino SLE patients with myocarditis is limited. This study aims to determine clinical characteristics and outcomes of myocarditis in Filipino patients with lupus. Methods: Review of medical records (between 2015 and 2017) of eight adult patients with lupus myocarditis in a tertiary government hospital was done. Clinical features, electrographic and echocardiographic findings, management, and outcomes were described. Results: All patients were females with a mean lupus duration of 10 months at the time myocarditis was diagnosed. Half of them had severe lupus activity, mostly with concomitant hematologic activity (100%) and nephritis (75%). Echocardiography showed wall motion abnormalities in all patients, with 63% having global hypokinesia and 75% having moderate to severe hypokinesia of the left ventricular wall. Treatment included methylprednisolone pulse therapy (88%) and high-dose steroids (13%). One patient died from cardiogenic and septic shock prior to receiving MPPT. Most patients (75%) were clinically improved at the time of discharge. Conclusion Filipino patients with lupus typically present with myocarditis early in the course of the disease, with high disease activity and concomitant hematologic activity and nephritis. Outcomes are generally favorable with early immunosuppressive therapy.
