Primary angioplasty: the past, the present and the future

Primary angioplasty (PTCA) in acute myocardial infarction has many theoretical advantages including better antegrade flow and reduced intracranial haemorrhage. However the improvement in the mortality and morbidity of primary angioplasty in the randomized trials from sophisticated centres has not been translated to the community setting. Primary PTCA is a suitable alternative to thrombolytic therapy if performed in a timely fashion by persons skilled in the procedure in a suitable laboratory. It is also recommended in patients with cardiogenic shock and in those with contraindications to thrombolytic therapy. Combination of thrombolytics and glycoprotein IIb/IIIa inhibitors with primary angioplasty may form the reperfusion strategy of the future.
