Cardiovascular Disease and Diagnostic Imaging Quiz

Outward Signs and Symptoms of Cardiovascular Disease & Diagnostic Imaging in the Cardiovascular System

• General observation of patients with cardiovascular disease can reveal signs of the disease in the hands, face, neck, trunk, and lower limbs.
• Hypercholesterolemia can cause xanthomas, corneal arcus, and cutaneous xanthelomatosis.
• Raynaud's phenomenon is a spasm of arteries that can cause reduced blood flow in the hands, which can lead to gangrene in severe cases.
• Heart failure can cause peripheral edema, shortness of breath, fatigue, and coughing.
• Central cyanosis can be seen in patients with chronic respiratory and/or cardiovascular disease.
• X-ray imaging uses high frequency electromagnetic waves to produce images of the body, which can reveal the position and size/shape of the aortic arch, clear lung fields, cardiac size, and costophrenic angle.
• Echocardiography uses sound waves to create moving images of the heart and is indicated for suspected valvular heart disease, abnormal left ventricular function, left ventricular hypertrophy, atrial fibrillation, embolus with a suspected cardiac source, pericardial disease, pulmonary embolism, and congenital heart defects.
• Doppler echocardiography can map the forwards and backwards direction of blood flow.
• Angiography involves injecting radio-opaque dye into arteries and taking x-rays in real time to visualize the extent of perfusion of the arteries and their branches.
• Coronary angiography is indicated in patients with symptoms of cardiac ischaemia/infarction and can help determine the site of narrowing/blockage of the coronary arteries.
• Limb angiography uses the same technique as coronary angiography to visualize the arteries in a leg.
• Kahoot quiz is available to test understanding of the material.
