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.

METHODS

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.

RESULTS

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.

CONCLUSION

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.

BACKGROUND

Balancing the benefits of preventing venous thromboembolism (VTE) against the risks of bleeding is important for patients who need prophylactic anticoagulants. This study compared which of the bleeding scores (IMPROVE and HAS-BLED BRS scores) is better at predicting anticoagulant-related bleeding events in critically ill and non-critically ill patients at a tertiary hospital who received prophylactic enoxaparin.

METHODOLOGY

Sixty-nine (69) patients in the ICU and ward who received prophylactic enoxaparin were included in the study and followed until discharge. Demographic data, comorbidities and IMPROVE and HAS-BLED BRS scores were recorded, and bleeding events monitored.

RESULTS

During the study, 16% (11/69) of the study population experienced bleeding events, both major and minor. Patients with IMPROVE BRS ≥ 7 (high risk) were more likely to bleed than those with scores of < 7 (low risk) (p < 0.001). The average HAS-BLED BRS was 2.20 (±1.09). Patients with higher HASBLED BRS scores had a slightly higher rate of bleeding (bleeding event, 2.73 [±1.19] versus no bleeding event, 2.09 [±1.04]), but this difference was not statistically significant (p = 0.079). The IMPROVE BRS had a higher area under the curve (AUC) (0.96) than the HAS-BLED BRS (0.67) in predicting anticoagulant-related bleeding events.

CONCLUSION

In patients receiving prophylactic anticoagulants for VTE, the IMPROVE BRS was better at predicting major anticoagulant-related bleeding events than the HAS-BLED BRS, with higher sensitivity, specificity and accuracy. Both risk scoring systems are useful for assessing bleeding risk before starting pharmacologic VTE prophylaxis, but the IMPROVE BRS is more accurate.

INTRODUCTION

The sudden designation as a COVID-19 Referral Center at the beginning of the pandemic brought about immense change to the Cardiac Catheterization Laboratory (CCL) services of a National Referral Center for tertiary care. As a proactive strategy to determine actions that can be undertaken should an unforeseen event ever happen again, this study was done to explore the impact of COVID-19 to the institution’s CCL caseload, and to review the challenges, innovations and adjustments made by the CCL to become pandemic-capable and crisis-ready.

METHODS

A qualitative cross-sectional study was conducted, with the first phase describing the CCL census starting from the baseline pre-COVID year of 2019 to the pandemic years of 2020-2022, and the second phase involving Key Informant Interviews (KII) and Focus Group Discussion (FGD) with the hospital and CCL healthcare staff.

RESULTS

The study revealed a large reduction in the urgent, elective and overall number of cases of the CCL in the first year, but has seen a steady increase in subsequent years. Surges of COVID variants were also seen to affect the CCL caseload. The following were noted to be the key elements in the CCL’s transformation to become COVID-19 capable: (a) changes in operations and patient selection, (b) appropriate use of PPE, (c) strict adherence to an infection control protocol, and (d) staffing modifications to reduce infectivity and protect staff availability.

CONCLUSION

The preparation of the hospital’s CCL to become a pandemic capable laboratory has been difficult and faced many challenges. However, the innovations and adjustments done through efforts and ingenuity of the CCL healthcare team allowed continuous delivery of the highest level of care to patients in spite of the changing pandemic landscape. These changes were duly documented as a basis for response to possible future global and/or national healthcare crises.

BACKGROUND

Blood pressure (BP) is a vital sign that is essential in the management of hypertension, thus, there is a need for accurate measurement of BP. This will allow for proper diagnosis and management of hypertension preventing cardiovascular morbidity and mortality among Filipino patients.

METHODOLOGY

This validation study utilized the US Association for the Advancement of Medical Instrumentation/European Society of Hypertension/International Organization for Standardization (AAMI/ESH/ISO) protocol for BP monitors. A total of eighty-five (85) participants had their BP measured using both the HEM 7156 and a validated aneroid sphygmomanometer. The same-sequential BP measurement was recommended to be used and a total of nine readings were collected per individual. The mean average of BP and standard deviation were extracted from the measurements. The AAMI/ESH/ISO recommends the use of certain criteria for individual BP readings (criterion 1) and individual participants (criterion 2). Appropriate statistical analysis was used for other demographic data.

RESULTS

The participants had an average age of 34 years, more than half were females, and not diagnosed with hypertension. Individuals who were diagnosed with hypertension had no other comorbidities and were on single pill only. The average arm circumference was 26.9 cm. Blood Pressure (BP) readings were adequate based on the protocol. Validity results showed that for criterion 1, systolic blood pressure (SBP) difference was 3.4 ± 7.4 mmHg, while diastolic blood pressure (DBP) was 2.0 ± 8.0 mmHg. The results for criterion 2 showed for SBP was 3.3 ± 5.3 mmHg, while DBP was 1.9 ± 6.6 mmHg. The results satisfied a passing grade on the validation protocol set by the AAMI/ESH/ISO.

CONCLUSION

This study showed that OMRON HEM 7156 is validated as a BP apparatus and may be recommended for Philippine use.

BACKGROUND

A patent and functional vascular access (VA) is the lifeline of hemodialysis patients. Prevention of VA failure and maintaining patency are crucial to ensure efficient dialysis, reduce morbidity, lessen healthcare costs and improve patient outcomes. This study aims to determine the risk factors of VA failure among hemodialysis dependent end-stage renal disease (ESRD) patients.

METHODOLOGY

This is a retrospective, case-control study conducted between July 2022 and December 2022. One hundred forty six ESRD patients consisting of 73 with VA failure and 73 without VA failure, undergoing hemodialysis in Manila Doctors Hospital (MDH) - Hemodialysis Unit were included in the study. At least one age (up to 5 years or younger) and sex-matched control was recruited per case (1:1 case-control sampling). The relation of patient demographic profile, smoking, comorbidities (ie, hypertension, diabetes, dyslipidemia, coronary artery disease [CAD], peripheral artery disease [PAD] and heart failure [HF]), duration of dialysis, location of VA, preoperative vessel diameter and arterial peak systolic velocity (PSV) and history of central vein catheterization to VA failure were analyzed. Odds ratio and their 95% confidence interval (CI) for the association of risk factors to VA failure were calculated.

RESULTS

Based on univariate analysis, the following are significant risk factors for VA failure: diabetes (OR 2.35, CI 1.20-4.62), CAD (OR 3.58, CI 1.58-8.13) and PAD (OR 3.04, CI 1.11-8.29). On multivariate analysis, two variables are significant risk factors associated with VA failure, namely: heart failure (OR 7.3, CI 2.15-21.4) and history of ipsilateral central venous catheter (OR 5.51, CI 1.99-15.3) (p = 0.05). Distal radiocephalic VAs have higher failure rates (53.42%) than proximal brachiocephalic (23.36%) and brachiobasilic (8.22%).

CONCLUSION

Diabetes, CAD, PAD, HF and history of ipsilateral central vein catheterization are significant risk factors for VA failure. Distal VA has higher failure rates compared to proximal access in these high-risk patients. This information may guide clinicians in making the appropriate recommendation regarding location of VA in this subset of patients. Aside from patient comorbidities, inherent characteristics, patency and functionality of VA vessels may be influenced by other extrinsic factors leading to VA failure.

INTRODUCTION

Heart failure (HF) remains a significant global health issue, affecting approximately 64 million individuals worldwide. In the Philippines, the prevalence aligns with global estimates, disproportionately affecting older populations.

METHODOLOGY

The Philippine National Heart Failure Network (PNHFN) conducted a cross-sectional survey from November 2021 to March 2022 to assess the landscape of HF management among medical professionals across the country.

RESULTS

A total of 1,649 physicians responded, primarily cardiologists (64%), internal medicine specialists (27%), and general practitioners (12%). While diagnostic tools such as electrocardiography (92%) and 2D echocardiography (85%) were widely available, advanced imaging modalities and specialized cardiac procedures, including cardiac catheterization and heart failure implantable devices, were less accessible outside metropolitan areas. Essential HF medications, including renin-angiotensin system blockers (84%), beta-blockers, and diuretics, were commonly prescribed; however, newer pharmacologic options such as sodium-glucose co-transporter 2 inhibitors remained underutilized.

CONCLUSION

Cardiac rehabilitation was accessible to less than half of respondents (48%), with unavailability cited as a major barrier. Despite these challenges, 97% of participants supported the establishment of HF programs to improve patient care and provider support. The findings highlight the need for improved access to advanced diagnostic and therapeutic modalities, enhanced education on guideline-directed HF management, and expanded infrastructure to bridge gaps in care delivery. Strengthening national HF initiatives and fostering collaboration among stakeholders are crucial in optimizing HF management and patient outcomes in the Philippines.

BACKGROUND

Large-vessel arterial thromboembolism is a rare initial presentation of acute myelogenous leukemia (AML). Aortoiliac occlusion is exceptionally uncommon and has not been previously reported in association with acute myelomonocytic leukemia (AML-M4).

CASE PRESENTATION

We present the first documented case of a 55-year-old female with AML-M4 who initially presented with recurrent respiratory infections and acute left leg ischemia, which responded to intravenous heparinization and femoropopliteal thromboembolectomy. However, progressive bilateral lower extremity ischemia revealed extensive thromboembolism involving the aortoiliac and bilateral femoropopliteal regions, requiring repeat thromboembolectomy and retrograde kissing balloon aortic angioplasty. Flow cytometry confirmed AML-M4 with CD13, CD33, CD11C and myeloperoxidase positivity. Her condition deteriorated due to multiple acute cerebrovascular infarcts, acute coronary thrombosis and sepsis, leading to her demise.

METHODS

A literature search of PubMed and Google Scholar (1980–2025) identified 51 cases of arterial thrombosis in AML.

RESULTS

Most patients were male (66%), with lower limb vessels (44%) as the most frequently affected sites. Acute promyelocytic leukemia (AML-M3) was the most common subtype. Management varied, including chemotherapy, anticoagulation and surgical or endovascular interventions.

CONCLUSION

The management of arterial thrombosis in AML is complex due to the competing risks of thrombosis, hemorrhage and infection. Early leukemia identification and timely chemotherapy initiation must be carefully balanced against the risks of cytopenias and immunosuppression in these critically ill patients.

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.

CASE DESCRIPTION

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.

DISCUSSION

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 country’s cardiology centers have been producing subspecialists in the field of Invasive and Interventional Cardiology. To date, 11 hospitals and/or medical centers are involved in training these subspecialists in a 1 to 2-year program. And to this date, there have been no uniform standards and guidelines as to what comprises the basic and/or acceptable training outcomes for the interventionalist in training. This paper describes the development of the core curriculum for an interventional cardiovascular training program to prepare its trainees to be competent in performing invasive diagnostic and interventional cardiovascular procedures as part of comprehensive patient care. The task force for the core curriculum of the interventional training program gathered several officers and leaders of the PSCCI, the training heads of the various interventional programs in the country, as well as experts in the field of cardiology education. Through a series of meetings, consultations, and workshops, the task force laid out the template on which all the training programs would be based. Such a framework considered the international standards regarding minimum caseloads for interventional training and the peculiar situation of each training institution. International standards like the Core Cardiovascular Training Statement (COCATS 4) Task Force 10: Training in Cardiac Catheterizations and the 2020 EAPCI Core Curriculum for Percutaneous Cardiovascular Interventions served as the reference framework for key recommendations. A consensus was achieved that upheld the highest standards of competence without disenfranchising certain institutions due to intricacies and uniqueness of hospital set-up and training situation.

Globally, an estimated 1.28 billion adults aged 30–79 years have hypertension (HTN), most of them (two-thirds) living in low- and middle-income countries (WHO 2023 report). The demographic of blood pressure (BP) in both genders differs with aging. In peopleyounger than 65 years of age, BP levels in men are higher compared to those of women. Conversely, at age 65 years and older, more women have been found to have elevated BP. Likewise, the cumulative incidence of increased adverse cardiovascular (CV) events in women has been reported as they age. Aside from aging, the influence of bio-social factors among women has been implicated in the development of HTN, such as health status—use of oral contraceptive pills (OCP), menopausal stage, obesity and having polycystic ovarian syndrome (PCOS) disease and socioeconomic condition—educational background, employment status and nuclear family setting. This paper will discuss how these factors affect the development of HTN and the approach of management among affected women from the reproductive to postmenopausal stage of life.
