Insights
Troponin I (Tn I) levels before and after percutaneous coronary intervention (PCI) predict cardiovascular events in ischemic heart disease patients. Elevated Tn I indicates higher risks of complications and mortality.
Area of Science:
- Cardiology
- Biomarkers
Background:
- Ischemic heart disease (IHD) poses significant cardiovascular risk.
- Percutaneous coronary intervention (PCI) is a common treatment for IHD.
- Troponin I (Tn I) is a cardiac biomarker used in diagnosing heart conditions.
Purpose of the Study:
- To investigate the prognostic significance of Troponin I (Tn I) levels before and after PCI.
- To correlate Tn I levels with cardiovascular event rates and mortality in IHD patients.
Main Methods:
- Study involved 150 patients with ischemic heart disease.
- Tn I levels were measured before and after PCI.
- Cardiovascular events and mortality rates were tracked.
Main Results:
- Normal Tn I levels pre- and post-PCI correlated with low cardiovascular event rates.
- Elevated Tn I post-PCI was linked to increased complications, especially in those with high pre-PCI Tn I.
- High Tn I pre-PCI predicted increased hospitalization and later mortality.
- Tn I elevation post-PCI in patients with normal baseline levels predicted 30-day mortality more strongly than later mortality.
Conclusions:
- Tn I levels before and after PCI are significant prognostic indicators in IHD.
- Pre-PCI Tn I is associated with hospitalization and long-term mortality.
- Post-PCI Tn I elevation is a critical predictor of short-term mortality.
Abstract:
Research has been carried out in TSMU Cardiology department of A.Aladashvili University Clinic involving 150 patients with ischemic heart disease. The changes of Tn level before and after percutaneous coronary intervention (PCI) in patients with CAD as well as its dependence on the cardiovascular events rate have been studied in previous work. In patients with normal Tn I level before and after PCI hospital cardiovascular events rate occurred to be as low as the rate of later events. Elevated level of Tn I after PCI was associated with increased rate of complications, which were mostly appeared in those patients with high level of Tn I before PCI. High level of 30-day mortality was revealed in patients with normal level of Tn I before PCI, which was elevated after procedure. The highest rate of later mortality was demonstrated in patients with high level of Tn I before PCI that was sustained after procedure. Hence, on the basis of our data we can conclude, that the Tn level before and after PCI has a prognostic significance; High level of Tn I before PCI is associated with increased hospitalization and later mortality rates. The elevation of Tn I after PCI in patients with normal initial level is more significant predictor of early (30-day) mortality compared to later (within 12 months) mortality.
