Why the study?
Does percutaneous coronary intervention performed more than two days after onset improve ECG and left ventricular function in a patient with marked ST-elevation myocardial infarction and no collateral circulation?
Does percutaneous coronary intervention performed more than two days after onset improve ECG and left ventricular function in a patient with marked ST-elevation myocardial infarction and no collateral circulation?
Late percutaneous coronary intervention performed more than two days after onset in a STEMI patient without collateral circulation can result in remarkable recovery of left ventricular function and normalization of ECG findings.
May allow LV recovery after late PCI in STEMI without collaterals; hypothesis-generating case report that leaves open broader applicability.
The patient was a 65-year-old man with marked ST-elevation myocardial infarction. Cardiac catheterization revealed an occluded middle portion of the left anterior descending artery and no collateral circulation. Percutaneous coronary intervention (PCI) was performed, and ST elevation improved 5 days after PCI. Almost all electrocardiogram (ECG) findings were normal 6 months later. Echocardiographic findings were also normal. This case was very successful and unusual in that no ventricular aneurysm formed despite ST elevation continuing for a few days and that ECG and left ventricular function were nearly normal after PCI performed days after the onset in a case without collateral circulation.
