The purpose of this study was to identify the characteristics and physiological variables of chest pain induced by exercise test in angina suspected patients. The subjects of this study consisted of 28 inpatients and outpatients aged between 40
and
75
who underwent treadmill test at exercise testing laboratory of S-University from January 2000 to June 2000. Subjects were interviewed with questionnaire regarding sociodemography, the past health history and history related to chest pain before
the
exercise test. Subjects were interviewed with questionnaire concerning quality, intensity, duration of chest pain induced by walking on the treadmill(Marquette, U.S.A. 1992) according to Bruce protocol following exercise test. Systolic and
diastolic
blood pressure were measured before, during and after the test, heart rate was determined by ECG. The results of this study were as follows ; 1) Quality of chest pain induced by exercise test were feeling stiffness 19(67.9%), heavy 10(36.0%),
exploded
9(32.1%), crushing, suffocating, tight 8(28.6%), stuffy, prickly 7(25.0%), burning 6(21.4%), clasp 5(17.9%), cleaved, tensed, piercing 3(10.7%), perfectly fitting, sore 2(7.1%), tearing, tingling, ticklish, heartburn 1(3.6%). 2) Mean score of
VAS(intensity of pain) following exercise test was 5.79±2.27 and mean duration of chest pain after the test was 7.83±5.31 minutes. 3) Sites of chest-pain induced by exercise test were middle site 11(39.3%), left-chest 10(35.6%), right-chest
6(21.5%).
Radiation site of chest-pain was neck(18.0%), right flank site 1(3.6%), left shoulder & arm 2(7.1%) and back 1(3.6%). 4) Symptoms other than chest-pain induced by exercise test were dyspnea 21(75.6%), perspiration 14(50.4%), fatigue 12(43.2%),
leg-pain
11(39.6%), dizziness 7(25.2%) anxiety toward chest-pain 3(10.8%), thirst 2(7.1%), and palpation, headache and tingling sensation of hand and leg 1(3.6%). 5) Mean MET(intensity of exercise) during the exercise test was 7.64±2.57 and mean
RPE(rating
of
perceived exertion) was 15.89±2.36. Mean duration of exercise was 6.79±2.88. 6) correlation coefficients between RPE and VAS was 0.500(p=0.003), those between MET and VAS was 0.287(p=0.069) and those between either depression or elevation of ST
segment and VAS was 0.236(p=0.114). 7) There was a significant difference in mean systolic pressure between before and after the test as 146.29±28.18㎜Hg and 177.96±28.82㎜Hg(t=-5.640, p=0.000), a significant difference in mean diastolic blood
pressure between before and after the test as 84.85±15.07㎜Hg and 88.89±13.72㎜Hg(t=-2.082, p=0.047), and there was a significant difference in mean heart-rate between before and after the test as 81.89±12.22/min and
160.68±21.77/min(t=-21.255,
p=0.000).
