ABSTRACT
BACKGROUND AND OBJECTIVES:
We investigated in patients with coronary vasospastic angina whether the exercise ECG test results are influenced by the different modes of exercise load and compared the clinical characteristics including coronary risk factors between patients with positive and negative exercise tests. MATERIALS ANDMETHODS:
This study comprised 34 patients with documented coronary artery spasm without significant stenosis (coronary artery luminal diameter narrowing 50%, <70% of luminal diameter) or total cholesterol level between patients with positive and negative results. In 18 typical variant angina patients by clinical history, 8 of 10 patients with high disease activity (5 times or more attack per week) manifested positive result by GET or NGET, whereas 4 of 8 patients with low disease activity (80 vs. 50%, P=NS).CONCLUSION:
In patients with coronary vasospastic angina, sudden rapid exercise could induce more frequently coronary artery spasm than multistage exercise. The result of an exercise test may not be correlated with coronary risk factors, coronary anatomy, effort chest pain, and the disease activity.
