The effects on blood pressure are well known, but that it can cause spasm of arteries is interesting.
Many people eat lots of spicy food daily and I never heard of serious health issues. Especially a single chip might contain a concentrated amount of capsaicin, but it is unlikely to contain much more in volume then a hot plate of chili con carne or even just a hand full of raw jalapenos. So I assume it is some underlying condition and a shock reaction and not the capsaicin itself.
