There has been no statistics found measuring this specific kind of human demise. Unless it draws attention, it goes unrecorded.
A Norwegian scientist published the first case report in 1968 about a rare condition called defecation syncope, a fancy term for the loss of consciousness, or fainting, that can occur while pooping.

Another study by Israeli physician, Dr B. A. Sikirov, emphasizes the connection between heart attack and your position while waste elimination.
Dr Sikirov singled out the Western toilet as a contributing factor in bathroom heart attacks.
The following is the summary of Dr Sikirov's article "Cardio-vascular Events at Defecation: Are They Unavoidable?" [Medical Hypotheses, Jul 1990; 32(3):231-3]:
"Heart attacks which occur during defecation are, in many cases, the result of using the (unnatural) sitting posture for waste elimination.
"Excessive straining, through the use of repeated Valsalva Maneuvers, is needed for emptying the bowels in the sitting position. The Valsalva Maneuver adversely affects the cardio-vascular system, and can cause fainting and death.
"The cardio-vascular system of a healthy man can cope with intensive and repeated straining on a sitting toilet. But with a weakened vascular system, straining on a sitting toilet may result in fainting or even death.
"By squatting for waste elimination, the straining required, if any, is much reduced, which would help prevent many of these tragic (heart attack) cases."
