Of 43 consecutive black patients (42 male) with sarcoidosis, 12 (28%) complained of chest pain that met the clinical criteria for typical (four patients) or atypical (eight patients) angina pectoris. These patients underwent cardiopulmonary assessment, which included exercise and redistribution thallium-201 scans and, if indicated, coronary angiography. Nine control patients with sarcoidosis matched for age and duration of disease, but without chest pain, were also studied by thallium-201 scintigraphy. Six of the 12 patients with chest pain had thallium scans indicative of myocardial ischaemia, but all had normal coronary angiograms; no patient from the control group had evidence of ischaemia on the thallium scan. Four additional patients with chest pain and one from the control group had other (non-specific) abnormalities on the thallium scan, so that scans were abnormal in 10 of the 12 patients with sarcoidosis who had chest pain. Most patients with anginal chest pain reported partial or complete relief of symptoms with nitrates. Anginal chest pain appears to be common in black male patients with sarcoidosis, is associated with abnormal myocardial perfusion scans, and may result from myocardial sarcoidosis.
在43例连续的结节病黑人患者(42例男性)中,12例(28%)主诉胸痛,符合典型(4例)或非典型(8例)心绞痛的临床标准。这些患者接受了心肺评估,包括运动和再分布铊-201扫描,如有指征则进行冠状动脉造影。9例年龄和病程匹配但无胸痛的结节病对照患者也接受了铊-201闪烁扫描研究。12例胸痛患者中有6例铊扫描显示心肌缺血,但冠状动脉造影均正常;对照组无患者铊扫描有缺血证据。另外4例胸痛患者和1例对照组患者铊扫描有其他(非特异性)异常,因此12例有胸痛的结节病患者中有10例扫描异常。大多数心绞痛性胸痛患者报告使用硝酸盐后症状部分或完全缓解。心绞痛性胸痛在结节病黑人男性患者中似乎很常见,与心肌灌注扫描异常有关,可能由心肌结节病引起。
