Article Synopsis
  • Percutaneous coronary intervention (PCI) is a common treatment for coronary artery disease but increases the risk of gastrointestinal bleeding (GIB) due to necessary antiplatelet medications.
  • A study at Sultan Qaboos University Hospital examined 435 patients who had PCI, finding that 3.4% experienced GIB within a year, with peptic ulcer disease being a significant cause.
  • The study emphasized the need for assessing bleeding risk before PCI, suggesting that high-risk patients could benefit from preventive measures like gastric protective agents.

First popularized almost a century ago in epidemiologic research by Ronald Fisher and Jerzy Neyman, the P-value has become perhaps the most misunderstood and even misused statistical value or descriptor. Indeed, modern clinical research has now come to be centered around and guided by an arbitrary P-value of <0.05 as a magical threshold for significance, so much so that experimental design, reporting of experimental findings, and interpretation and adoption of such findings have become largely dependent on this "significant" P-value.

Background And Objectives: Cardiovascular diseases (CVD) are associated with substantial psychological effects that can adversely influence long term prognosis. The aim of this study was to determine the psychological effect of the first hospital admission for acute coronary syndrome (ACS) or congestive heart failure (CHF) in an adult Omani population.

Methods: This cross-sectional questionnaire based study used the Hospital Anxiety and Depression Scale.

Angina pectoris remains a significant burden despite advances in medical therapy and coronary revascularization. Many patients (up to 30%) with angina have normal coronary arteries, with coronary microvascular disease and/or coronary artery vasospasm being major drivers of the myocardial demand-supply mismatch. Even among patients revascularized for symptomatic epicardial coronary stenosis, recurrent angina remains highly prevalent.

Environmental temperature is now well known to have a U-shaped relationship with cardiovascular (CV) and all-cause mortality. Both heat and cold above and below an optimum temperature, respectively, are associated with adverse outcomes. However, cold in general and moderate cold specifically is predominantly responsible for much of temperature-attributable adversity.

Objectives: Critically ill patients have raised troponins. This study aimed to assess the incidence of myocardial injury in the intensive care unit (ICU) at a tertiary care hospital and assess the management and prognosis.

Methods: This retrospective study included adult patients who were admitted to the ICU of Sultan Qaboos University Hospital, Muscat, Oman, between January and December 2019 and had undergone a high-sensitive cardiac troponin (hs-cTn) assay.

Article Synopsis
  • The May Measurement Month (MMM) program is a global initiative focused on screening blood pressure (BP), and this report summarizes data from Oman spanning 2017-2019, involving 15,679 individuals.
  • Out of those screened, 1,004 were newly diagnosed with hypertension, leading to a hypertension prevalence rate of 30.1% among the cohort; 43% of patients on antihypertensive medications still had high BP.
  • The study found significant correlations between BP and both body mass index (BMI) and age, with particular ethnic groups (Arab and South Asian) showing higher BMI and BP levels, highlighting the need for targeted monitoring in high-risk populations.

Aim: The aim of this study was to evaluate the progression of tricuspid regurgitation (TR) in patients with pacemaker leads across the tricuspid valve and assess the clinical effect on right ventricular (RV) function.

Methods: Patients who had undergone permanent pacemaker implantation at our institution over an 8-year period were identified. Those who had an echo (for any indication) pre- and postdevice implantation were included in this study, and their data assessed.

Managing a high intracoronary (IC) thrombus burden is a major challenge in patients with ectatic coronary arteries who present with an ST-elevation myocardial infarction (STEMI). We report a 45-year-old male patient who presented to the Department of Medicine, Sultan Qaboos University Hospital, Muscat, Oman, in 2017 with an inferior STEMI. Coronary angiography revealed ectatic coronary arteries with an occluded right coronary artery (RCA).

Aim: Coronary interventions are increasingly being performed via the radial rather than femoral route because of the lower complication rate. Compression devices such as the TR band are used to achieve hemostasis after the procedure. At present, there are no clear protocols for the deflation of the band.

Cardiac complications are the major cause of mortality in patients with Thalassemia major (TM). Cardiac T2* MRI is currently the gold standard for assessing myocardial iron concentration. The aim of our study was to assess whether any echocardiographic parameter would correlate with these findings in patients well established on chelation therapy.
