Abstract:
BACKGROUND:Anti-ischaemic therapy with nitrates and/or calcium channel blockers profoundly affects the results of pharmacological stress echocardiography with coronary vasodilators but the influence on catecholamine stress testing remains unsettled. AIMS:The present study aimed to assess the effects of non-beta-blocker antianginal therapy on dobutamine (up to 40 micrograms.kg-1.min-1)-atropine (up to 1 mg) stress. echo-cardiography and to evaluate whether drug-induced changes in the dobutamine atropine stress echocardiography response may predict variations in exercise tolerance. METHODS:Twenty six patients with angiographically assessed coronary artery disease (seven patients with single-, 10 with double-, and nine with triple-vessel disease) performed a dobutamine atropine stress echocardiography and an exercise electrocardiography test in random order both off and on antianginal drugs (nitrates and calcium antagonists). In doubtamine-atropine stress echocardiography, we evaluated: dobutamine time (i.e. the time from initiation of the dobutamine infusion to obvious dyssynergy), wall motion score index (in a 16-segment model of the left ventricle, each segment ranging from 1 = normal, to 4 = dyskinetic), and rate-pressure product at peak stress. RESULTS:Dobutamine-atropine stress echocardiography positivity occurred in 26 out of 26 patients off and in 23 patients on therapy (100 vs 88%, P = ns). Atropine coadministration was needed to evoke echo positivity in no patient off and in five out of 26 on therapy (0 vs 19% P < 0.01). The achieved rate pressure product during dobutamine-atropine stress echocardiography was comparable on and off therapy (17 +/- 4 vs 19 +/- 5 x 10(3) mmHg x heart rate. min-1, P = ns). Therapy induced an increase in dobutamine time (on = 16 +/- 3 vs of = 13 +/- 3 min, P < 0.01) and a decrease in peak wall motion score index (on = 1.3 +/- 0.2 vs off = 1.5 +/- 0.3, P < 0.01). The therapy induced changes in exercise time during the exercise electrocardiography test were not significantly correlated to dobutamine-atropine stress echocardiography variations in either dobutamine time (r = 0.07, P = ns), or peak rate pressure product (r = 0.24, P = ns), or peak wall motion score index (r = 0.02, P = ns). CONCLUSIONS:(1) non-beta-blocker antianginal therapy only modestly reduces dobutamine-atropine stress echocardiography sensitivity, although atropine coadministration is more often required to reach stress echo positivity under therapy; (2) therapy reduces the severity of dobutamine atropine stress echocardiography ischaemia stratified in the time and space domain, but these changes are only poorly correlated to variations in exercise tolerance.
