FIGURE 1. BMIPP scintigrams of vasospastic angina before and after medical treatment of 50-y-old man (patient 1 in group II). Patient had spontaneous vasospastic attacks, and coronary vasospasm was induced in LAD, LCX, and RCA by ergonovine provocation. Decreased BMIPP uptake was seen in anterior, interventricular septum, inferior, and apex regions (BMIPP-1). TDS of BMIPP was 19. Decreased MIBG uptake was observed in anterior, lateral, and inferior regions (MIBG-1). TDS of MIBG was 21. After 6 mo of medical treatment, anginal attacks were completely suppressed and vasospasm was not reinduced by ergonovine provocation. TDS and percentage improvement of BMIPP were 4 and 79% (BMIPP-2). Regions of decreased MIBG uptake were alleviated 6 mo after treatment, except in inferior region (MIBG-2). TDS and percentage improvement of MIBG were 10 and 52%. A, B, C, and D indicate basal short-axis, midventricular short-axis, vertical long-axis, and horizontal long-axis images, respectively.
