Quantitative evaluation of exercise Tl-201 myocardial scintigraphy before and after transluminal coronary angioplasty A preliminary report.

Short- and long-term changes in myocardial perfusion after percutaneous transluminal coronary angioplasty assessed by thallium-201 exercise scintigraphy.

Exercise electrocardiography and myocardial scintigraphy in the serial evaluation of the results of percutaneous transluminal coronary angioplasty.

The diagnostic value of exercise electrocardiography using 14 leads and thallium-201 scintigraphy were evaluated in 54 of 70 patients who underwent percutaneous transluminal coronary angioplasty (PTCA), both in the initial assessment and serial follow-up of patients after PTCA. Of the 45 patients who had successful PTCA, 36 had complete noninvasive studies performed before and 1 month after PTC...

Late symptomatic exercise-induced coronary vasospasm after percutaneous transluminal coronary angioplasty. A case report and review.

A patient who underwent a successful double-vessel percutaneous transluminal coronary angioplasty (PTCA) had suffered from exercise-induced ST-segment elevation associated with angina pectoris (AP). This ECG pattern was present both before and 12 months after PTCA while nifedipine (Adalat; Bayer-Miles) therapy was electively discontinued. Reintroduction of calcium blockade with this drug elimin...

Twenty-four-hour Tl-201 delayed scan underestimates myocardial viability in patients with acute myocardial infarction after percutaneous transluminal coronary angioplasty.

BACKGROUND Myocardial viability in area at risk of acute myocardial infarction (AMI) after reperfusion therapy may be underestimated by the 24-hour images due to reverse redistribution (r-RD). METHODS Subjects were 37 AMI patients in whom Tc-99m pyrophosphate (PYP)/Tl-201 dual-isotope SPECT was positive. The 24-hour delayed scan was performed with only a Tl window. One month later, follow up ...

Exercise stress testing before and after successful multivessel percutaneous transluminal coronary angioplasty.

Controversy exists regarding the diagnostic accuracy, optimal technique, and timing of exercise testing after percutaneous coronary intervention. The objectives of the present study were to analyze variables and the power of exercise testing to predict restenosis or a new lesion, 6 months after the procedure. Eight-four coronary multi-artery diseased patients with preserved ventricular function...
