Andy Warhol's *How to Tell You're Having a Heart Attack* employs his signature silkscreen technique to transform a mundane public health advisory into a striking work of pop art. Bold, flat colors and repeated text fragment the clinical medical information into an almost decorative visual experience, blurring the line between life-saving communication and commercial graphic design. The work reflects Warhol's enduring fascination with mass-media imagery and the way urgent, even life-or-death messages are packaged and consumed by the public.
