Beyond the Bedside: Machine Learning-Guided Length of Stay (LOS) Prediction for Cardiac Patients in Tertiary Care.

Efficient management of hospital resources is essential for providing high-quality healthcare while ensuring sustainability. Length of stay (LOS), measuring the duration from admission to discharge, directly impacts patient outcomes and resource utilization. Accurate LOS prediction offers numerous benefits, including reducing re-admissions, ensuring appropriate staffing, and facilitating informed discharge planning.

The clinical and Practice Dilemma of Frequent Switching Among Generic Medications: Magnitude and Patient Safety Prospective.

To assess the magnitude of generic-generic and brand-generic medication switching and its impact on patients' understanding and the potential risk of medication errors. The study composed of 2 parts. The first part is a retrospective study to measure the frequency of medications switching in King Faisal Specialist Hospital and Research Centre (KFSH&RC), from 1 of January 2015 to the 31 of December, 2020.

A complex unit for a complex disease: the HCM-Family Unit.

Hypertrophic cardiomyopathy (HCM) is a group of heterogeneous disorders that are most commonly passed on in a heritable manner. It is a relatively rare disease around the globe, but due to increased rates of consanguinity within the Kingdom of Saudi Arabia, we speculate a high incidence of undiagnosed cases. The aim of this paper is to elucidate a systematic approach in dealing with HCM patients and since HCM has variable presentation, we have summarized differentials for diagnosis and how different subtypes and genes can have an impact on the clinical picture, management and prognosis.

Preoperative Assessment and Management of Cardiovascular Risk in Patients Undergoing Non-Cardiac Surgery: Implementing a Systematic Stepwise Approach during the COVID-19 Pandemic Era.

Major adverse cardiac events, defined as death or myocardial infarction, are common causes of perioperative mortality and major morbidity in patients undergoing non-cardiac surgery. Reduction of perioperative cardiovascular risk in relation to non-cardiac surgery requires a stepwise patient evaluation that integrates clinical risk factors, functional status and the estimated stress of the planned surgical procedure. Major guidelines on preoperative cardiovascular risk assessment recommend to establish, firstly, the risk of surgery per se (low, moderate, high) and the related timing (elective vs.

Percutaneous Coronary Intervention Vs Coronary Artery Bypass Surgery for Unprotected Left Main Coronary Disease: G-LM Registry.

Coronary artery bypass surgery (CABG) has been the standard of care for revascularization for patients with obstructive unprotected left main coronary disease (ULMCA). There have been multiple randomized and registry data demonstrating the technical and clinical efficacy of PCI in certain patients with ULMCA. The purpose of this study is to evaluate clinical outcomes of ULMCA PCI as compared to CABG in patients requiring revascularization in three Gulf countries.

Augmentation index predicts mortality in patients with aortic stenosis: an echo-tracking study.

Aortic valve stenosis (AS) shares similarities with the atherosclerotic process but little is known about the effect of the mechanical properties of large arteries on outcome in patients with AS. The aims of this study were (1) to determine the relationship between indexes of carotid stiffness/compliance and the severity of AS and (2) to identify whether local arterial stiffness is independently associated with mortality. 133 patients with moderate to severe isolated AS and preserved LV ejection fraction (LVEF) were included.

Transcatheter mitral valve-in-valve implantation for failed bioprosthesis.

Objective: This study is a report of clinical and echocardiographic outcomes of experience with transapical mitral valve-in-valve (VIV) replacement.

Methods: Eleven patients with a mean age of 63.7±13.

Imaging Cardiovascular Emergencies: Real World Clinical Cases.

Cardiovascular emergencies represent life-threatening conditions requiring a high index of clinical suspicion. In an emergency scenario, a simple stepwise biomarker/imaging diagnostic algorithm may help prompt diagnosis and timely treatment along with related improved outcomes. This article describes several clinical cases of cardiovascular emergencies, such as coronary stent thrombosis-restenosis, takotsubo syndrome, acute myocarditis, massive pulmonary embolism, type A acute aortic dissection, cardiac tamponade, and endocarditis.

Outcomes of Routine Coronary Angiography in Asymptomatic Patients With End-Stage Renal Disease Prior to Kidney Transplantation.

We report the prevalence of coronary artery disease (CAD) in asymptomatic patients with end-stage kidney disease (ESKD) on hemodialysis and explore the best revascularization strategies prior to kidney transplantation. This is a retrospective single-center study, which included all patients who were candidates for kidney transplantation and underwent coronary angiography between 2003 and 2018. All included patients underwent coronary angiography without noninvasive testing and were asymptomatic cardiac-wise.

Breast arterial calcification on mammography does not predict coronary artery disease by invasive coronary angiography.

Background: The relationship between breast arterial calcification (BAC) and angiographic coronary artery disease (CAD) is uncertain. Some studies have shown a positive association between BAC and angiographically proven CAD, while other studies have shown no association.

Objective: Examine the association between visually detected BAC on mammography and CAD found on invasive coronary angiography (ICA) in women and compare the frequency of risk factors for CAD between women with normal and abnormal ICA.

A rare case of takotsubo syndrome within the first day after heart transplantation.

A 39-year-old woman underwent heart transplantation (HTx) for advanced heart failure. The donor was a 36-year-old young woman without past medical history. The first day after HTx, T-waves changes were noted.

Diagnostic accuracy of N-ammonia myocardial perfusion imaging with PET-CT in the detection of coronary artery disease.

Background: N-ammonia positron emission tomography-computed tomography (PET-CT) is being increasingly used as a non-invasive imaging modality for evaluating patients with known or suspected coronary artery disease (CAD), but information about the diagnostic accuracy of PET-MPI is sparse. Objectives: Our objective was to determine the accuracy of N-ammonia PET-CT myocardial perfusion imaging (MPI) for detecting CAD.

Methods: We retrospectively evaluated 383 patients with suspected CAD who underwent rest-stress N- ammonia PET-CT MPI.

Immediate and intermediate results of intracoronary stand-alone bolus administration of eptifibatide during coronary intervention (ICE) study.

Background: This study evaluated the immediate and intermediate results of intracoronary (i.c.) eptifibatide administration during percutaneous coronary intervention (PCI).

Long-term results (up to 16.5 years) of mitral balloon valvuloplasty in a series of 518 patients and predictors of long-term outcome.

Objectives: To assess the long-term results (up to 16.5 years) of mitral balloon valvuloplasty (MBV) and to identify predictors of restenosis and event-free survival.

Methods And Results: We report the immediate and long-term clinical and echocardiographic results in 518 patients, mean age 31 +/- 11 years, who underwent successful MBV for severe mitral stenosis (MS) and were followed up for 0.

Amyloid heart disease. New frontiers and insights in pathophysiology, diagnosis, and management.

Amyloidosis comprises a unique group of diseases that share in common the extracellular deposition of insoluble fibrillar proteins in organs and tissues. Cardiovascular amyloidosis can be primary, a part of systemic amyloidosis, or a result of chronic systemic diseases elsewhere in the body. The most common presentations are congestive heart failure-mainly a restrictive infiltrative pattern--and conduction system disturbances.

False positive ST segment elevation during dobutamine stress echocardiography due to left ventricular hypertrophy.

The significance of ST segment elevation in dobutamine stress echocardiography (DSE) remains controversial. In patients with prior Q wave myocardial infarction (MI), it may reflect myocardial ischemia, contractile reserve in the infarct-related area, or dyskinesia of the infarcted areas of myocardium. In the nonpost-MI population, it has been attributed to vasospasm or strongly associated with coronary artery disease and ischemia.
