    The influence of the triiodinated angiographic contrast medium Visotrast 370 on haemostasis was studied in a total of 30 angiographic examinations with and without previous injection of 5,000 IU heparin. The contrast medium alone caused prolongation of bleeding time and inhibition of plasmatic coagulation. The effect of the contrast medium was enhanced by injection of heparin. The fibrinogen concentration remained unchanged in all cases. Aggregation of platelets enhanced by the contrast medium was found to be further increased by heparin. Enhanced platelet aggregation is considered an essential factor in the incidence of thromboembolic complications during engiographic examinations. Since heparin does not inhibit platalet function, the use of inhibitors of aggregation is discussed.

    Radiological Investigation I: X-ray and CT

    Radiological investigations, including X-rays and computed tomography (CT) scans, are critical for diagnosing and evaluating various medical conditions. These imaging techniques provide valuable insights into the body's internal structures, aiding in the detection of abnormalities, assessment of disease progression, and development of treatment strategies. This article delves into two primary radiological investigations, chest X-rays and CT scans, outlining their purpose, procedures, and the...

    Imaging Studies for Cardiovascular System V: CT

    Cardiac computed tomography (CT) scanning is an advanced cardiac imaging technique that utilizes CT technology, with or without intravenous (IV) contrast, to produce accurate cross-sectional virtual slices of specific areas of the heart, coronary circulation, and major blood vessels such as the aorta, pulmonary veins, and arteries. The computer processes these slices to generate three-dimensional images. Multidetector CT (MDCT) is a rapid form of CT scanning that captures multiple slices...

    Cardiac Catheterization I: Pre-Procedure Overview

    Cardiac catheterization is an invasive diagnostic technique used to identify and evaluate structural and functional diseases of the heart and major blood vessels. This technique diagnoses congenital heart disease, coronary artery disease, valvular heart disease, and coronary spasms and assesses ventricular function. It helps guide treatment decisions, including the need for revascularization procedures like percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG) and...

    Nursing responsibilities before cardiac catheterization include:Assess for allergies and establish baseline health status.Before cardiac catheterization, assess the patient for allergies to contrast dye. Perform a comprehensive baseline assessment, including vital signs, heart and breath sounds, and a neurovascular assessment of the extremities, noting distal pulses, skin color, and temperature. Instruct the patient to fast for 8-12 hours before the procedure. Evaluate baseline laboratory...
