What Happens to Your Body in the First 60 Seconds of a Heart Attack

What Happens to Your Body in the First 60 Seconds of a Heart Attack Somewhere inside your chest, a piece of plaque the size of a grain of rice can rupture without warning, and the next sixty seconds decide everything. This is the real, sourced, second-by-second biology of a heart attack: plaque rupture, platelet aggregation, thrombus formation, the switch to anaerobic metabolism, and the referred pain that reaches your brain, plus the quiet warning signs most people miss days beforehand, why heart attacks look different in women, and the golden window that determines who survives. This video is general health education based on cardiology and public health research. It is not a diagnosis and not a substitute for professional medical care.
