From the Research
Calcichew (calcium carbonate) is typically recommended for 3-6 months after coronary artery bypass graft (CABG) surgery to help maintain adequate calcium levels, which are essential for proper bone health and cardiac function, as supported by the most recent evidence 1. The standard dosage is usually 500-1000mg twice daily, taken with meals to enhance absorption. This supplementation is particularly important because post-surgical stress and certain medications used after CABG can affect calcium metabolism. Some key points to consider:
- Adequate vitamin D intake (typically 800-1000 IU daily) should accompany calcium supplementation since vitamin D facilitates calcium absorption 2.
- Patients should continue their regular cardiac medications alongside calcium supplements but should take them at different times to avoid potential interactions, especially with certain antibiotics or blood pressure medications.
- If you experience constipation, a common side effect, increasing fluid intake and dietary fiber can help.
- Regular blood tests to monitor calcium levels may be recommended by your healthcare provider to adjust dosage as needed throughout the recovery period. It's also important to note that disorders of calcium metabolism, such as hypocalcemia and hypercalcemia, can have significant effects on the body, and monitoring of calcium levels is crucial in patients after CABG surgery 1. Additionally, recent studies have highlighted the importance of optimal medical therapy after CABG, including lipid-lowering, diabetes management, antithrombotic therapy, and anti-inflammatory therapy, to reduce the risk of cardiovascular events and death 3. However, the use of Calcichew after CABG is primarily focused on maintaining adequate calcium levels, and its duration and use should be guided by the most recent evidence and individual patient needs 1.
