Key result
Semiemergent angioplasty for unstable angina with severe LAD achieves ~90% ECG resolution at 28 weeks.
Why the study?
Does semiemergent percutaneous transluminal coronary angioplasty improve clinical and electrocardiographic variables in patients with unstable angina secondary to isolated severe proximal left anterior descending coronary artery disease?
Observational (n=76)
Does semiemergent percutaneous transluminal coronary angioplasty improve clinical and electrocardiographic variables in patients with unstable angina secondary to isolated severe proximal left anterior descending coronary artery disease?
Semiemergent angioplasty for severe LAD disease and unstable angina has a high initial success rate, but ECG changes (ST-T wave inversion) may persist for up to 7 months despite successful revascularization.

Successful semiemergent PTCA was associated with ECG and clinical improvement in proximal LAD unstable angina; leaves open randomized confirmation of outcome benefit.
Shawl et al. (1990) conducted an observational in Unstable angina secondary to isolated severe proximal left anterior descending coronary artery stenosis (n=76). Semiemergent percutaneous transluminal coronary angioplasty was evaluated on Complete resolution of ST-T wave changes at 28 weeks. Semiemergent coronary angioplasty for unstable angina secondary to severe LAD disease achieved a 92% success rate, with complete resolution of ECG ST-T wave changes in 90% of patients at 28 weeks.
