Cardiac enzyme test is a blood test that measures specific biomarkers, such as troponin and CK-MB, released into the bloodstream when heart muscle is damaged. It is a critical diagnostic tool for detecting acute myocardial infarction and assessing the severity and timing of heart attacks. Elevated cardiac enzymes, especially with characteristic patterns over time, confirm heart muscle injury even when EKG findings are equivocal. In life insurance underwriting, records of elevated cardiac enzymes signal significant cardiac events and often justify heavy ratings, postponements for stabilization, or declines depending on overall cardiac function and follow-up.

Underwriters review cardiac enzyme test results found in hospital records when evaluating applicants with suspected or confirmed heart attacks. They consider peak troponin levels, associated EKG changes, interventions such as angioplasty or bypass surgery, and subsequent recovery documented in cardiology follow-up notes. Advisors working with heart-attack survivors gather discharge summaries and cardiology records that explain the cause, treatment, and current status. They prepare clients for the likelihood of table ratings and waiting periods before coverage is available on favorable terms. Understanding cardiac enzyme tests helps advisors interpret hospital records and communicate the seriousness of cardiac events in underwriting discussions.
