Effects of medical therapy on outcome assessment using exercise thallium-201 single photon emission computed tomography imaging

Abstract: In patients with coronary heart disease, the introduction of antianginal medications, when including beta-blockers, appears to have a favorable effect on the deleterious prognostic effect of exercise ischemia.

“…Consistently, in a similar comparative study of exercise and adenosine stress in CAD patients without beta-blocker treatment, more chest pain during exercise than during adenosine stress has been reported [35]. Furthermore, Marie et al [36]recently indicated that beta-blockers have favorable effects on the extent of reversible defects and on event-free survival supporting that betablockers reduce ischemia, which is in accordance with the present results. Since follow up data for our patients are not available we cannot answer the question whether adenosine overestimates risk or whether exercise underestimate risk in these patients.…”

“…Radionuclide investigations. The way to perform and analyze exercise 201 Tl-SPECT images has already been described in detail elsewhere (10,11). Briefly, an exercise test was performed in the upright position on a bicycle ergometer; the protocol was started at 20 W and increased by 20 W every 2 min.…”

“…De nombreuses études ont établi l'importance pronostique des anomalies objectivées en TSM de stress, et que ces informations étaient complémentaires de celles obtenues par l'angiographie coronaire [1][2][3]. Dans une méta-analyse, Metz et al [4] ont confi rmé l'excellente valeur prédictive négative d'une TSM normale, que ce soit pour les événements cardiaques majeurs (décès ou infarctus non fatal) ou pour le taux de revascularisation (tableau I).…”

“…Le retentissement sur la perfusion d'eff ort dépend de plusieurs paramètres peu ou pas accessibles à l'angiographie coronaire : l'effi cacité de la circulation collatérale [7], la majoration des sténoses par une vasoconstriction coronaire d'eff ort liée à une dysfonction endothéliale [8], et l'effi cacité des traitements médicaux en cours [2]. Ainsi, des ischémies parfois sévères peuvent se voir dans des territoires de sténoses coronaires peu serrées à la coronarographie.…”
