Another yes here too! Heart attacks occur when your heart for some reason doesn't get the oxygen
it needs for a period of time. There are things that can cause the vessels of the heart to spasm and for a split second close down the heart vessels and cause heart attack pain. Then there is the whole blocked artery
thing. That usually happens over a period of time and as plaque
builds up in the vessels the pathway gets narrower and regardless of what someones BP is...they're heading for a heart attack. High blood pressure
adds to the problem by stressing the heart, making the vessels less elastic, causing kidney
damage (which affects BP too). A low blood pressure is helpful but it ain't a completely safe insurance policy! Hope this helps. Jeff the nurse in Nashville.
