Is the "Warm-up effect" in angina mediated by improved myocardial perfusion?

Journal article

Introduction. Considerable doubt remains about whether the "warm-up" effect in angina represents ischaemic preconditioning (IPC), or is simply due to improved myocardial perfusion via acute recruitment of collaterals. We investigated the latter possibility using quantitative tetrofosmin SPECT. Methods. 11 patients (age 63±8 years, 8 male) with coronary disease and preserved left ventricular function underwent symptom-limited treadmill exercise off antianginal medication.
