INTRODUCTION

The existence of a coronary artery aneurysm (CAA) can pose significant risk for death. It can cause thrombosis, dissection, rupture or myocardial infarction. An exceedingly rare involvement of the left main coronary artery (LMCA), particularly giant-sized is even more catastrophic, a finding seen in only 0.1% of patients. Furthermore, co-existence with significant stenotic coronary artery disease (CAD) portends grim survival. Owing to the rarity of this combination, no data is available locally and only limited case reports are documented internationally. Hence, no consensus guidelines have been published yet. This paper aims to contribute to the sparse medical knowledge on the treatment approach and management of LMCA aneurysm with concomitant CAD.

A 62-year-old male, Filipino, hypertensive and hyperlipidemic sought consult due to one-year exertional chest pain. Coronary angiogram revealed the LMCA to be a diffusely aneurysmal, large-sized vessel measuring 9.7 mm x 7.9 mm with a significant two-vessel CAD affecting the proximal left anterior descending (LAD) and right coronary artery (RCA). As per multidisciplinary decision, the patient underwent surgical revascularization via cardiopulmonary bypass graft (CABG) addressing the CAD and LMCA aneurysm managed conservatively through guideline-directed medical therapy. The patient’s course of treatment was uneventful. He returned for follow-ups for three months post-surgery and remained symptom-free.

Giant coronary artery aneurysms (GCAA) are vessel dilatations that exceed 4x the diameter of a normal adjacent artery. The patient had a unique case of GCAA involving the LMCA combined with two-vessel CAD. Few studies have documented a medical or surgical approach and long-term outcomes are unknown. Without sufficient evidence-based guidelines, the multidisciplinary decision was to perform CABG and manage the LMCA aneurysm conservatively.

Due to extremely limited information available on the giant LMCA aneurysm natural history, definitive management remains controversial. A multidisciplinary team approach is highly recommended for patient-specific needs to achieve favorable outcome and ensure survival.

INTRODUCTION

Coronary artery disease remains a leading cause of mortality worldwide. Although advances in percutaneous coronary intervention (PCI) and stent technology have improved outcomes, in-stent restenosis (ISR) persists as a significant challenge contributing to repeat revascularization, rehospitalization, increased healthcare costs and adverse outcomes.

A single-center retrospective cohort study reviewed medical records from January 2021 to December 2024 to determine the incidence, risk factors and clinical outcomes associated with ISR.

Among 200 patients, ISR occurred in 58 (29%). Factors significantly associated with ISR included hypertension (p = 0.048), smaller stent diameter (OR=0.23, pCONCLUSION

ISR remains a substantial and multifactorial clinical burden highlighting the need for vigilant post-PCI surveillance, aggressive risk factor management and individualized interventional strategies—including optimal stent sizing, lesion preparation and adjunctive imaging use—to reduce restenosis risk and improve long-term outcomes.

Introduction: Homozygous familial hypercholesterolemia (HoFH) is a rare inherited disorder characterized by markedly elevated low-density lipoprotein cholesterol (LDL-C) from birth, childhood xanthomas, and accelerated atherosclerotic cardiovascular disease. Achieving LDL-C targets remains difficult despite statins, ezetimibe, and lipoprotein apheresis, especially in patients with treatment interruption, poor adherence, or limited access to specialized lipid services. We report a female with genetically confirmed HoFH who developed severe premature coronary artery disease and showed marked lipid reduction after inclisiran therapy. Case: A 28-year-old Malay female with LDL receptor mutationconfirmed HoFH, diagnosed at age 7, had a strong family history of premature cardiovascular death. She underwent biweekly lipoprotein apheresis from ages 8 to 15 years, but later defaulted on follow-up. During pregnancy in 2021, weekly then biweekly apheresis was reintroduced for severe hypercholesterolemia, but she disengaged postpartum. In 2025, she re-presented with exertional chest pain, orthopnea, and palpitations. Examination showed widespread xanthomas. Electrocardiography demonstrated sinus tachycardia with inferolateral ST depression. Echocardiography revealed a left ventricular ejection fraction of 40%, anterior and septal akinesia, severe mitral regurgitation, moderate tricuspid regurgitation, and pulmonary hypertension. Her lipid profile showed total cholesterol 18.1 mmol/L and LDL-C 14.9 mmol/L. Coronary angiography demonstrated triple-vessel disease with left main stem involvement and critical right coronary ostial stenosis. Coronary artery bypass grafting was advised but declined. She was treated with high-dose rosuvastatin, ezetimibe, dual antiplatelet therapy, and inclisiran 284 mg. After one dose of inclisiran, total cholesterol fell to 6.78 mmol/L and LDL-C to 4.71 mmol/L, a reduction of more than 60%. Conclusion This case highlights the aggressive natural history of inadequately controlled HoFH and the importance of sustained lifelong therapy. Inclisiran may provide additional LDL-C reduction in selected HoFH patients, although long-term cardiovascular outcome data remain limited.

BACKGROUND

Myocardial bridging (MB) is a congenital coronary anomaly characterized by an epicardial coronary artery taking an intramuscular course, causing systolic compression of the tunneled segment. In comparison to coronary artery disease (CAD), myocardial bridges have been uncommonly associated with acute coronary syndromes and sudden cardiac death.Evidence of accelerated atherosclerotic plaque formation proximal to the bridged segment may increase the risk for future adverse cardiac events in these patients.

This Single–Center Retrospective Study included 323 adult in-patients who underwent coronary angiography for suspected myocardial ischemia in 2022. Clinical information and in-hospital outcomes were obtained by review of medical records.

Myocardial bridging was observed in 31 out of 323 patients (9.60%), with the majority in the mid-left anterior descending artery (87.10%). MB was more prevalent in females (56.62%), and these patients were younger than patients with obstructive CAD (56.9 versus 63.6 years). Chronic Coronary Syndrome was more prevalent in the MB group (82.62%). The coronary segment proximal to the area with MB showed the concurrent presence of obstructive CAD in 16.12% and non-obstructive CAD in 29.03% of cases. In-hospital mortality occurred in 4.44% of the studied population. However, there were no mortalities in the MB group.

Among patients admitted for suspected myocardial ischemia, 9.6% had MB. These patients were younger and, more often, female. Obstructive and non-obstructive CAD were noted in bridged vessels. Although patients with obstructive CAD have a higher risk of experiencing in-hospital death and cardiac complications, evidence of increased atherosclerotic plaque formation in bridged vessels has important implications for future adverse cardiac events and repeat hospitalizations in the MB population. Aggressive risk factor modification, emphasis on long-term follow-up, and the establishment of clinical practice guidelines are therefore necessary for patients with MB.

BACKGROUND OF THE STUDY

Coronary artery disease (CAD) poses a significant global health challenge. In the Philippines, despite increased availability of coronary artery bypass grafting (CABG), cost remains a barrier to access. This research evaluates key factors such as all-cause death, cardiovascular death, repeat revascularization and quality of life post-CABG under the Philippine Health Z Benefit Package (PZBP). Its findings provide critical insights for shaping clinical practices, policymaking and advocating for broader implementation of the PZBP to improve healthcare access and quality of life for post-CABG patients.

This retrospective cross-sectional study explores the outcomes of post-coronary artery bypass grafting (CABG) patients enrolled under the PZBP. The study, conducted at Perpetual Succour Hospital in Cebu City from December 2018 to September 2023, included patients diagnosed with CAD based on ACC/AHA 2021 guidelines. Using a complete enumeration strategy, the research employed descriptive statistics for demographic and clinical profiling, and measured quality of life using the World Health Organization Quality of Life Brief Version (WHOQOL-BREF) tool.

The study analyzed 29 patients who underwent CABG through the PZBP, presenting detailed demographic and clinical data. Most patients (41.4%) fell within the 51-60 age range, with males comprising 75.9%. Diabetes mellitus type II was prevalent (58.6%) and 86.2% had three-vessel diseases. The quality of life assessed with WHOQOL-BREF yielded positive scores across physical, mental, social and environmental domains, indicating favorable outcomes. Notably, no cardiovascular deaths, all-cause deaths, or repeat revascularizations were reported during the study, highlighting the effectiveness of CABG under PZBP.

The study on post-CABG patients under the PZBP shows promising outcomes with no all-cause death, cardiovascular death, or repeat revascularization. This indicates the program's effectiveness in delivering accessible, high-quality healthcare, enhancing long-term survival rates and overall well-being. However, addressing underutilization is crucial, highlighting the importance of raising awareness and utilization to further improve post-CABG patients' outcomes and quality of life.

BACKGROUND: Non-alcoholic fatty liver disease (NAFLD), now known as Metabolic Dysfunction-Associated Fatty Liver Disease (MAFLD), is linked to cardiovascular disease. This renaming emphasizes the role of metabolic problems. Coronary artery calcification (CAC) reflects early coronary artery disease, but data on the MAFLD-CAC link is limited. OBJECTIVE: To demonstrate the association between metabolic dysfunction-associated fatty liver disease (MAFLD) based on its criteria and coronary artery calcification, as measured by CT CAC score. METHODS: This single-center retrospective study involved adult Filipino patients who underwent CT CAC scoring between January 2021 and January 2023. Clinical and laboratory data were obtained via review of electronic records. RESULTS: This study involved 147 patients with an average age of 62 years, primarily females (57.14%), and mostly falling into the Obese-Class I category (31.29%). The most common comorbidities were hypertension (95.24%), dyslipidemia (62.59%), and diabetes mellitus (38.1%). In terms of CAC scores using the CT Agatston method, majority (30.61%) had low calcium buildup (Stage 2 with scores between 1-99). Approximately 26.53% had higher liver fat content with liver HU below 40, while 73.47% had lower liver fat content with HU equal to or greater than 40. Furthermore, 25.17% of patients with fatty livers and other risk factors were diagnosed with MAFLD, while 74.83% were not. The p-value indicated a significant difference in proportions, suggesting a lower proportion of MAFLD among those who had undergone CT CAC scoring. However, the Pearson Chi-Square statistic (4.051) and the p-value (0.256) indicated no statistically significant association between MAFLD and CT CAC. CONCLUSION The study found a notably lower proportion of MAFLD diagnoses in patients who underwent CT CAC scoring. Additionally, there was no statistically significant link between MAFLD and CT CAC.

Coronary artery disease (CAD), one of the most common cardiovascular diseases (CVD), poses a serious threat to physical and mental health, resulting in a severe disease burden. Psychocardiology medicine focuses on the vital role of psychological factors in the development, diagnosis, and treatment of CVD. The prevalence of depression and anxiety is high in patients with CAD. Furthermore, there is a vital interplay among depression, anxiety, mental stress-induced myocardial ischemia, cognitive impairment, and delirium. Both cognitive impairment and delirium adversely impact the prognosis of patients with CAD, warranting increasing attention and the development of interventions. To further direct the clinic diagnosis and treatment of cognitive impairment in patients with CAD complicated with depression and anxiety, and to thus improve the prognosis of such patients, the Psychocardiology Medicine Branch of Chinese Medical Association Beijing Branch, and Psychocardiology Education Professional Committee of China Medical Education Association, together with over 40 other organizations, including more than 50 experts from several related fields, have developed the association standards on guidelines for the cognitive clinical diagnosis and treatment of CAD complicated with depression and anxiety under the framework of the China standard association (No.T/CAS 812-2024).

Objective To develop a diagnostic model combining the CT angiography(CCTA)-derived myocardial radiomics signatures with the CT-derived fractional flow reserve(CT-FFR)based on coronary CCTA and investigate the diagnostic accuracy of the hybrid model for hemodynamically significant coronary artery disease(CAD).Methods The patients presenting stable angina pectoris,diagnosed with CAD,and clinically referred for CCTA examination and invasive coronary angiography were prospectively recruited.Radiomics features of the left ventricular myocardium were extracted from the three main perfusion territories demarcated according to the coronary blood supply.The extracted features were first selected by the minimum redundancy maximum relevance feature ranking method.A least absolute shrinkage and selection operator Logistic regression algorithm with leave-one-out cross-validation was then employed to construct a radiomics model.The CT-FFR value was generated for each blood vessel.The area under the receiver operating characteristics curve(AUC_ROC),sensitivity,and specificity were adopted to evaluate the performance of each model against the reference standard invasive coronary angiography/FFR.Results A total of 70 patients[42 men and 28 women;(61±10) years old] were included in this study and complemented CCTA examination,with 175 vessels and the corresponding myocardial territories undergoing invasive coronary angiography/FFR.A total of 1 656 specific radiomics parameters were extracted,from which 14 features were selected to establish the radiomics model.The AUC_ROC,sensitivity,and specificity were 0.797(95%CI=0.732-0.861),77.1%,and 73.7%for the radiomics model,0.892(95%CI=0.841-0.943),81.4%,and 88.8%for the CT-FFR model,and 0.928(95%CI=0.890-0.965),83.3%,and 88.4%for the hybrid model,respectively.The hybrid model outperformed the radiomics model and CT-FFR alone(P=0.040).Conclusions The radiomics signatures of the vessel-related myocardium from CCTA could provide incremental value to the diagnostic performance of CT-FFR and improve vessel-specific ischemia detection.The hybrid model combining CT-FFR with radiomics signatures is potentially feasible for improving the diagnostic accuracy for hemodynamically significant CAD.
