Which retraction cord is contraindicated for patients with cardiovascular disease?

• A. Cord impregnated with epinephrine
• B. Cord with aluminum chloride
• C. Cord without any additives
• D. Cord impregnated with sodium bicarbonate

Answer: (A)

The retraction cord that is contraindicated for patients with cardiovascular disease is the one impregnated with epinephrine. Epinephrine, a vasoconstrictor, is often used in dental practices to control bleeding and help with tissue management during dental procedures. However, in patients with cardiovascular disease, especially those with conditions such as hypertension or heart disease, the use of epinephrine can pose significant risks. It can lead to increased heart rate, elevated blood pressure, and could potentially trigger serious cardiovascular events. Retraction cords that contain other substances, such as aluminum chloride or those that are free of additives, do not carry the same level of risk for patients with cardiovascular issues. Aluminum chloride, for example, is used primarily for hemostatic purposes and is considered safer for those with cardiovascular concerns. Similarly, cords without additives do not introduce any additional stimuli that could affect cardiovascular function, making them a safer choice. Cord impregnated with sodium bicarbonate primarily aids in neutralizing acidity but does not carry the same risks associated with epinephrine. Thus, for patients with cardiovascular disease, avoiding retraction cords with epinephrine is essential to ensure their safety during dental procedures.
