Heat stroke as a cause of death is a bit nebulous, in that it can cause parts of the body to fail that otherwise wouldn't. It's similarly fuzzy to dying of old age: If someone has a heart attack, and they're 95 years old, did they die of heart failure or die of old age? If someone has a heart attack, and it's 120°F outside, did they die of heart failure or die of heatstroke? Heat deaths are typically underreported because of this.
