Study Notes

Objectives of Advanced Cardiovascular Skills

Recognize retinal changes due to hypertensive vascular disease.
Perform and document a peripheral vascular exam.
Set up an EKG appropriately.

Retinal Examination

Visualizes blood vessels affected by hypertension and chronic diseases like diabetes.
Progressive retinal microvascular changes occur with increased hypertension.

Hypertensive Retinopathy

Mild: Includes arteriolar narrowing, thickening (copper wiring), and arteriovenous nicking.
Moderate: Presents with hemorrhages (flame or dot-shaped), cotton-wool spots, hard exudates, and microaneurysms.
Severe: Includes all moderate findings plus optic disc edema (papilledema).

Retinal Changes Defined

Copper Wiring: Arterioles appear orange or yellow instead of red.
Silver Wiring: Arterioles look white due to occlusion.
Cotton Wool Spots: Result from microinfarction.
AV Nicking: Retinal arterioles indent veins at crossings.
Retinal Hemorrhages and Hard Exudates: Indicative of vascular issues.

Peripheral Vascular Exam Components

Conduct in four regions: Eyes, Neck, Abdomen, Extremities.

Neck Examination

Inspect and palpate external and internal carotid arteries.
Listen for carotid artery pulses and assess for bruits (abnormal sounds).

Jugular Venous Pressure (JVP)

Reflects pressure in the right atrium; indicates central venous pressure.
Fluctuations provide insights into volume status and heart function.
Increased JVP associated with heart failure or constriction.
Check JVP with the patient supine at 45°, observing right neck.
Use the abdomino-jugular test to confirm JVP readings.

Abdominal Examination

Auscultate with a stethoscope (bell) over major arteries: aorta, renals, iliacs, femorals.

Extremities Examination

Inspect for color changes, ulcers, scars, and hair loss.
Palpate to assess temperature changes.
Check capillary refill and evaluate pulses.
Assess for edema and conduct special tests (e.g., Allen Test, Ankle-Brachial Index (ABI)).
Begin with thorough inspection for a comprehensive assessment.
