Overview:
Over the past 6 years, Shuangbo Liu and her fellow researchers from the University Of Manitoba looked at every ST-elevation myocardial infraction (STEMI) that occurred in Winnipeg. In other words, they studied every severe heart attack that happened in the province throughout the 12 months of the year for 6 years. The cardiology expert and her helpers from the university found out that during the colder parts of the year in Canada, your chances of a heart attack raise 7% for every 10 C it drops below 0 C. In Winnipeg, the days that daily high was 0 C or below, the heart attack rates for 0.93 per day. When the temperature low was above 0 C , the heart attack rates were 0.78 per day, this stayed consistent throughout the 6 years. Even though the heart rate risk increases as temperatures drop, they say that does not make the cold the ultimate cause for a heart attack. Liu and her researchers said they can use this methodology to help prevent heart attacks in the future. Since Winnipeg has a population of over 700,000 and has very cold winters, it made it the perfect place to conduct the experiment. The next step for Lui and her team is to conduct these experiments outside of Winnipeg, and use what they find to hopefully in the future help predict heart attacks days prior to the day it really happens.

Opinion:
When I first found this article and started to read it, I became more interested as
in went on mainly because I know people who have had heart attacks during the
cold months of the year. I find it very interesting that the lower the
temperature drops, the higher the risk of a heart attack becomes. To conduct an
experiment about this for 6 years and finding a slimier pattern throughout that
time, makes the data they collected seem fair and reliable. The only thing I came up with in my head to know why you're more likely to have a heart attack
when its cold is because I think the cold air when in hailed may shorten your
breath and not give your lung as much oxygen as normal air. That is just my
thought from experience, when its colder I find it harder to breath. One
question that I have which was unanswered and makes me wonder is how they can
use this data to help prevent heart attacks for the future. If they can use
this data to one day help find a way to prevent or give notice when a heart
attack will happen, it may be very crucial to saving lives. Overall I found
this article to be very interesting and gave me more knowledge about something I did not know before.
