Measurement of Troponin in Cardiomyopathies
Key result
Elevated cardiac troponin in cardiomyopathies is linked to poor prognosis and strong negative predictive value.
Why the study?
Does elevated cardiac troponin predict poor prognosis in patients with cardiomyopathies?

Structured PICO
Does elevated cardiac troponin predict poor prognosis in patients with cardiomyopathies?
P
Population
Patients with cardiomyopathies
I
Intervention
Measurement of cardiac troponin (TnI and TnT)
O
Outcome
Prognosis (adverse cardiovascular events and mortality)
Elevated cardiac troponin levels in patients with cardiomyopathies are consistently associated with poor prognosis, highlighting their potential utility in risk stratification.
Limitations
- Considerable variability among studies regarding assays used and definitions of abnormal results
- Studies in cardiomyopathies are generally small with <200 patients
Cite This Study
Connelly et al. (2016) conducted a review in Cardiomyopathies. Cardiac troponin measurement was evaluated on Prognosis. Elevated cardiac troponin levels in cardiomyopathies are consistently associated with poor prognosis and have an important negative predictive value.
