Serum cardiac troponin T (cTnT), cardiac troponin I (cTnI), creatine kinase-MB (CK-MB mass), myoglobin, and H-FABP were determined pre-angioplasty and 1, 2, 4, and 16–24 hrs post-angioplasty. Elevated cardiac markers were correlated with demographic, angiographic and procedural variables. Patients were followed up for 20–26 months. </span><strong><em>Results:</em></strong><span> H-FABP peaked early at 2 hours and was useful for the early detection of evolving AMI within 1–3 hours after angioplasty. Cardiac-TnI, myoglobin, H-FABP, CK-MB mass, and cTnT concentrations were elevated in 46.25%, 17.5%, 13.3%, 11.25%, and 7.5% respectively. Cardiac-TnI was the most sensitive marker for detecting all complications and was superior to all other markers. Elevated cardiac markers were correlated with old age (P < 0.02); chest pain ± ECG changes of ischaemia (P < 0.003); use of stents (P < 0.019) and major complications such as major dissection (P < 0.004); transient vessel closure (P < 0.022); bail out stent (P < 0.003), and AMI (P < 0.042). Elevated cardiac markers were associated with a reduction of event-free survival (16.92 versus 20.67 months, P < 0.03). </span><strong><em>Conclusion:</em></strong><span> Heart-type-FABP measurements at 1 hour (or thereafter) post-PCI may offer an early chance of detecting evolving AMI; cTnI was the most sensitive marker for the detection of major complications in patients undergoing PCI. Measurements of cTnI 16–24 hours post-PCI should be part of the routine management of patients following elective PCI.</span><br /><br /><br />}, number={1}, journal={Sultan Qaboos University Medical Journal}, author={Alhadi, Hafidh A and Fox, Keith A A}, year={2010}, month={Apr.}, pages={31–40} }
