New heart attack insight could lead to better survival rates after surgery (Troponin levels low = Get surgery early)

New research shows how doctors can improve the timing of surgery for some heart attack patients by analyzing the levels of a particular protein.

Troponin is a protein involved in muscle contraction that is released into the bloodstream after a heart attack. Clinicians use troponin levels, along with other tests, to determine whether a patient is having a heart attack and to decide on treatment options such as coronary artery bypass graft (CABG) surgery.

In the study, researchers found that some patients who have lower levels of troponin would benefit from having earlier surgery. However, the researchers show that patients with very high troponin levels should have surgery postponed, as their risk of dying was higher if surgery was performed within 10 days of their heart attack.

There was no benefit in delaying surgery for those with low levels of troponin, according to the study.

The researchers found that pre-operative troponin level was a strong predictor of early mortality, and this was significantly influenced by the interval to surgery. The average wait for patients with high troponin levels to surgery was nine days. They found that for those who had troponin levels of less than 100 times the normal upper limit, delaying surgery to after 10 days was not associated with lower survival. For patients with higher troponin levels, early survival increased progressively with a longer time to surgery—survival was highest in those who had surgery after day 10.

Dr. Amit Kaura said, "For patients with troponin levels of under 100 times the normal upper limit, extending the waiting time or surgery did not improve early survival."

Less time in the hospital means less cost and less likelihood of a hospital-acquired issue.
