Background: Coronary artery disease (CAD) is a highly prevalent condition which can lead to myocardial ischemia as well as acute coronary syndrome. Early diagnosis of CAD can improve patient outcomes through guiding risk factor modification and treatment modalities.
Summary: Testing for CAD comes with increased cost and risk; therefore, physicians must determine which patients require testing, and what testing modality will offer the most useful data to diagnose patients with CAD. Patients should have an initial risk stratification for pretest probability of CAD based on symptoms and available clinical data. Patients with a pretest probability less than 5% should receive no further testing, while patients with a high pretest probability should be considered for direct invasive coronary angiography. In patients with a pretest probability between 5 and 15%, coronary artery calcium score and or exercise electrocardiogram can be obtained to further risk stratify patients to low-risk versus intermediate-high-risk. Intermediate-high-risk patients should be tested with coronary computed tomography angiography (preferred) versus positron emission tomography or single photon emission computed tomography based on their individual patient characteristics and institutional availability.
Key Messages: This comprehensive review aimed to describe the available CAD testing modalities, detail their risks and benefits, and propose when each should be considered in the evaluation of a patient with suspected CAD.

Background: Developmental delay is a group of disorders that cause common deficits of adaptive and intellectual function in children. It happens when a child fails to achieve one aspect of developmental skills. Limited information is available regarding the prevalence of developmental delay among children aged 12-59 months in the study area.

With the advent of treatments that specifically target Alzheimer's disease brain pathology, biomarker tests will become an increasingly important part of the routine clinical evaluation of cognitive impairment and guide clinical decision making. Clinicians must ensure they are using accurate and well-validated biomarker tests and select the most appropriate testing modality for each patient based on individual and practical considerations. The interpretation of test results may be complex and depends on the pre-test probability and test-specific factors.

Background: Legumes are widely considered one of the most beneficial food groups to consume. They are high in fibre and plant-based protein as well as naturally low in sodium, saturated fats, and sugars. However, legumes do not feature prominently in the modern diet, and previous evidence syntheses show inconsistent results on cardiometabolic risk profile when increasing legume intakes.

Globally, the prevalence of coronary artery disease (CAD) is increasing, accounting for a third of all deaths worldwide including myocardial infarctions (MIs) which represent the most severe clinical manifestation of CAD and are among the most dangerous coronary events. Therefore, this study aims to assess the knowledge of symptoms and risk factors of MIs, as well as attitudes and beliefs regarding MIs and confidence in recognizing CAD symptoms in Riyadh, Saudi Arabia. A cross-sectional study was conducted among individuals living in Riyadh, Saudi Arabia between November 2023 and April 2024 to assess their knowledge and beliefs about CAD and MIs.
