Objective: To evaluate the impact of Breast Reconstructive Surgery (BRS) on patients' satisfaction and quality of life following mastectomy for breast cancer.

Methods: A multi-method design study comprising quantitative and qualitative research was conducted between October to December 2019. The quantitative component consisted of a cross-sectional study using the Breast-Q questionnaire and the qualitative component involved in-depth interviews with eligible patients (N = 16) who underwent BRS following mastectomy for breast cancer.

A case report: anteroseptal ST elevation due to acute isolated right ventricular infarction.

Background: Electrocardiogram (ECG) is the first diagnostic tool physicians use in diagnosing acute myocardial infarction (MI). In this case report, we present a case where the initial ECG diagnosis was that of an acute anteroseptal MI but emergency coronary angiography showed that the infarct-related artery was a small non-dominant right coronary artery (RCA) instead of the anticipated left anterior descending artery (LAD). Isolated right ventricular (RV) infarction from a non-dominant RCA is rarely seen in clinical practice, and it may exhibit ECG changes that can be confused with an acute anteroseptal MI.

Long-term outcomes in acute coronary syndrome patients without standard modifiable risk factors: a multi-ethnic retrospective cohort study Of 5400 asian patients.

A sizeable number of patients without standard modifiable cardiovascular risk factors (SMuRFs), such as hypertension, diabetes, hypercholesterolemia and smoking, suffer from acute coronary syndrome (ACS). These SMuRF-less patients have high short-term morbidity and mortality. We compared both short- and long-term outcomes of SMuRF-less and SMuRF ACS patients in a multi-ethnic Asian cohort.

Characteristics and outcomes of patients with coronary artery ectasia presenting with ST-segment elevation myocardial infarction undergoing primary percutaneous coronary intervention.

Background: The clinical significance of coronary artery ectasia (CAE) is not yet fully understood. We aimed to examine differences in clinical and procedural characteristics, clinical management, and outcomes in patients with CAE undergoing primary percutaneous coronary intervention (PPCI) for ST-elevation myocardial infarction (STEMI).

Methods: This was a retrospective analysis of consecutive patients presenting with STEMI with a culprit native coronary artery from July 2015 to June 2019.

An Asian Perspective on Gender Differences in In-Hospital and Long-Term Outcome of Cardiac Mortality and Ischemic Stroke after Primary Percutaneous Coronary Intervention for ST-Segment Elevation Myocardial Infarction.

Objectives: Gender differences historically exist in cardiovascular disease, with women experiencing higher rates of major adverse cardiovascular events. We investigated these trends in a contemporary Asian cohort, examining the impact of gender differences on cardiac mortality and ischemic stroke after primary percutaneous coronary intervention (PPCI) for ST elevation myocardial infarction (STEMI).

Materials And Methods: We analysed 3971 consecutive patients who underwent primary PCI for STEMI retrospectively.

Recurrent Stent Thrombosis Secondary to Immunoglobulin G4-Related Disease.

Immunoglobulin G4-related disease (IgG4-RD) is an insidiously progressive multiorgan disease. However, lack of familiarity with IgG4-RD results in patients often being undiagnosed and undertreated. IgG4-RD can affect any organ, and manifests as aortitis within the cardiovascular system.

Long-Term Clinical Outcomes of Biodegradable-Polymer Drug-Eluting Stents Versus Second-Generation Durable-Polymer Drug-Eluting Stents for ST-Segment Elevation Myocardial Infarction.

Background: Biodegradable polymer drug eluting stents (BP-DES) may offer the advantage of vascular healing in ST-segment elevation myocardial infarction (STEMI). Long-term outcome data comparing BP-DES and second-generation durable polymer drug eluting stents (DP-DES) in STEMI is lacking. This study aims to compare the long-term clinical outcomes of BP-DES versus second-generation DP-DES in STEMI.

Characteristics and outcomes of young patients with ST segment elevation myocardial infarction undergoing primary percutaneous coronary intervention: retrospective analysis in a multiethnic Asian population.

Objective: ST segment elevation myocardial infarction (STEMI) is associated with significant mortality leading to loss of productive life years, especially in younger patients. This study aims to compare the characteristics and outcomes of young versus older patients with STEMI undergoing primary percutaneous coronary intervention (PPCI) to help focus public health efforts in STEMI prevention.

Methods: Data from the Coronary Care Unit database of the National University Hospital, Singapore from July 2015 to June 2019 were reviewed.

Spontaneous coronary artery dissection: clinical implications and diagnostic challenges. Overlooked and underappreciated in Asia?

Over the last decade, spontaneous coronary artery dissection (SCAD) has garnered much attention as a significant cause of acute coronary syndrome (ACS) and sudden cardiac death in women without classic cardiovascular risk factors. SCAD has been mostly studied in the West, with little recognition in Asia leading to under-diagnosis and under-representation. In this review, we highlight two distinct cases occurring at our center in Singapore, affecting two Singaporean women of Malay and Chinese descent.

Treating Very Long Coronary Artery Lesions in the Contemporary Drug-Eluting-Stent Era: Single Long 48 mm Stent Versus Two Overlapping Stents Showed Comparable Clinical Outcomes.

Background/purpose: Percutaneous coronary intervention (PCI) of diffuse coronary artery disease (CAD) is associated with higher adverse clinical events. This study aimed to compare the clinical outcomes of patients treated with single long 48 mm contemporary drug eluting stents (SL-DES) versus two overlapping contemporary drug eluting stents (OL-DES) for very-long CAD.

Methods/materials: We analyzed the clinical outcome of 117 patients with SL-DES and 101 patients with OL-DES who underwent PCI between 1st July 2013 to 31st December 2016.

Clinical Outcomes One Year and Beyond After Combination Sirolimus-Eluting Endothelial Progenitor Cell Capture Stenting During Primary Percutaneous Coronary Intervention in ST-Segment Elevation Myocardial Infarction.

Background/purpose: Primary percutaneous coronary intervention (PCI) during acute ST-segment elevation myocardial infarction (STEMI) represents a thrombotic milieu and is associated with delayed healing after stenting. The pro-healing combination sirolimus eluting endothelial progenitor cell (EPC) capture stents encourage early endothelialization after stenting and may be beneficial in the STEMI population. We aim to evaluate the clinical outcomes one year and beyond for patients with STEMI who received the combination sirolimus eluting EPC capture stents during primary PCI.
