The relational inquiry approach enables nurses to understand and examine different nursing situations within complex healthcare contexts using the ideologies of pragmatism, critical theory, and hermeneutic phenomenology. In this paper, the author presents the application of the relational inquiry approach using Newman's theory to analyze a case of a man who refused coronary artery bypass surgery in Pakistan. This analysis demonstrates that relational inquiry is useful in examining patients' experiences and related healthcare needs and helps the nurses to perform appropriate actions to produce desirable outcomes...

BACKGROUND: Metabolic acidosis, a common condition particularly in the end-stage of renal disease patients, results in malnutrition, inflammation and oxidative stress. In this study, we focused on the association between low serum bicarbonate and cardiovascular disease in patients on intermittent dialysis. METHODS: We studied 52 on-line-pre-dilution hemodiafiltration (on-l HDF) patients, 32 males and 20 females, with a mean age of 58.01 ± 15.4 years old. Metabolic acidosis was determined by serum bicarbonate concentrations less than 22 mmol/L...

We describe the case of a 10-year-old male with a history of repaired Tetralogy of Fallot and known intramural right coronary artery (RCA) who presented for bioprosthetic pulmonary valve replacement. The operation was complicated by postoperative ventricular fibrillation arrest. Selective coronary angiography revealed external compression of the mid-RCA by a mediastinal chest tube that improved immediately upon removal of the tube. Ultimately, the patient required additional unroofing of the intramural coronary for full recovery...

Reduced blood flow in the coronary arteries can lead to damaged heart tissue (myocardial ischaemia). Although one method for detecting myocardial ischaemia involves changes in the ST segment of the electrocardiogram, the relationship between these changes and subendocardial ischaemia is not fully understood. In this study, we modelled ST-segment epicardial potentials in a slab model of cardiac ventricular tissue, with a central ischaemic region, using the bidomain model, which considers conduction longitudinal, transverse and normal to the cardiac fibres...

The best surgical approach for coarctation of the aorta (COA) combined with other cardiac diseases is uncertain. The simultaneous intracardiac repair of complex pathologies is desirable because multistage procedures may lead to a higher rate of mortality. We describe a case involving a 61-year-old woman who was suffering from COA with a concomitant arch aneurysm and coronary artery disease. We managed her case via single-stage surgery that included a median sternotomy.

BACKGROUND: Sleep apnoea hypopnoea syndrome (SAHS) is characterised by repetitive nocturnal hypoxemia and has a high prevalence among patients with acute myocardial infarction (AMI). But there are few studies on patients with AMI undergoing emergency primary percutaneous coronary intervention (pPCI). In this study, we want to find the prevalence of SAHS among patients with AMI undergoing emergency pPCI and determine whether SAHS would worsen the condition among these people, and especially affect the damage degree of the coronary artery...

Since the emergence of stents, there has been persistent improvement in flexibility and deliverability of stents with modifications in its design and number of connectors. This has unfortunately created negative effect on longitudinal strength of stent resulting into a recently recognized and unaccustomed complication, longitudinal stent deformation (LSD). It is an abrupt shortening of the stent along its longitudinal axis, usually after deployment, due to various reasons. We present a case of LSD in Promus Element stent implanted at proximal left anterior descending artery...

INTRODUCTION: Atrial fibrillation (AF) is the most common arrhythmia affecting patients in open heart ICU after coronary artery bypass grafting (CABG). Most cardiac surgery textbooks recommend beta blockers as the drug of choice for treating such a condition while many experienced physicians and a number of anesthesiology references offer amiodarone as the drug of choice. Therefore, because of insufficient evidence and the aforementioned controversy, we decided to conduct a study evaluating these two antiarrhythmic medicines...

Development of coronary artery aneurysm (CAA) after implantation of drug-eluting stent is occasionally observed. We present a case of a 67-year-old man who underwent everolimus-eluting stent (EES) implantation in right coronary artery (RCA) for inferior wall myocardial infarction, and thereafter, giant CAAs were developed in the vessel of stent deployment, within 2 months. However, the patient was managed with coronary artery bypass grafting (CABG). On follow-up, the patient's condition was stable. To the best of our knowledge, we report the first case of occurrence of EES-associated giant CAAs in RCA subsequently treated with CABG...

We describe the case of a patient presenting with ST-segment elevation myocardial infarction due to very late scaffold thrombosis. The patient was already admitted for an elective percutaneous recanalization of a chronically occluded left anterior descending artery (LAD). The procedure was performed according the sub-intimal tracking and re-entry (STAR) technique with 4 bioresorbable vascular scaffolds implantation. However, even though the coronary flow was preserved at the end of the procedure, the dissected segment was only partially sealed at the distal segment of the LAD...

Research revealed that the pathogenesis of aortic stenosis (AS) not merely comprises of a mechanical wear and tear process yet that active biological processes, similar to those of coronary artery disease are involved, a promising role for statins in disease-modifying therapy was suggested. However, recently, many prospective studies could not observe decreased progression nor regression of the disease. Here, we review the current knowledge on the pathomechanisms of AS and its similarities and differences with atherosclerosis...

Over the course of the 3 decades, percutaneous coronary intervention (PCI) with stent implantation transformed the practice of cardiology. PCI with stenting is currently the most widely performed procedure for the treatment of symptomatic coronary disease. In large trials, drug-eluting stents (DES) have led to a significant reduction in in-stent restenosis (ISR) rates, one of the major limitations of bare-metal stents. Due to these favorable findings, DES was rapidly and widely adopted enabling more complex coronary interventions...

OBJECTIVE: Invasive coronary angiography remains the cornerstone for evaluation of coronary stenoses despite there being a poor correlation between luminal loss assessment by coronary luminography and myocardial ischemia. This is especially true for coronary lesions deemed moderate by visual assessment. Coronary pressure-derived fractional flow reserve (FFR) has emerged as the gold standard for the evaluation of hemodynamic significance of coronary artery stenosis, which is cost effective and leads to improved patient outcomes...

AIMS: Tumor necrosis factor (TNF)-α reportedly has key pro-inflammatory properties in both atherosclerosis and adipocytes. To further investigate the biologic impact of epicardial adipose tissue (EAT) on coronary atherosclerosis, we evaluated the relationship between TNF-α gene expression in EAT and clinically-assessed coronary atherosclerosis on computed tomography (CT). METHODS: We studied 47 patients before cardiac surgery (coronary artery bypass grafting [CABG], n=26; non-CABG, n=21), assessing visceral adipose tissue (VAT) area, EAT volume, coronary calcium score (CCS), and the presence of non- and/or partially-calcified coronary plaque (NCP) on CT angiography...
