Foreign media pain, the higher the risk of myocardial infarction

 

myocardial infarction is the life and health of human body, with the "three high" prevalence rate increased, work pressure increasing, myocardial infarction also grow with each passing day. This is a clinical emergency, such as the symptoms of suspected myocardial infarction due to immediate medical treatment, time is the heart, time is life".

mentioned myocardial infarction, most people are familiar with acute chest pain, such as "a man clutched his chest, frowning," from Norway, Dr. Andrea Ohrn of the University of main cable, a see will know that it is a heart attack, need as soon as possible first aid; however, there is a lot of people have experienced not aware of, also known as "asymptomatic myocardial infarction", and will not attack is particularly uncomfortable.

although no reason symptoms of myocardial infarction is not clear at present, but recently, a new study suggests that "pain" is perhaps one of the reasons for the occurrence of myocardial infarction "secretly".

The

researchers asked subjects to do two experiments. The first experiment is to let them put their hands in icy water, to see how long, can persist for more than two minutes; second is the use of ECG, to see if there are ST-T segment changes and the emergence of new Q wave, and the blood of myocardial enzyme (marker physical changes of myocardial injury), to determine whether patients have recently had myocardial ischemia or myocardial infarction, and even some are not aware of the myocardial infarction can also be found.

has over people to participate in the test, 8% of whom had myocardial infarction, while less than 5% can be diagnosed and compared between the two groups; the experimental results can be found, had no symptoms of myocardial infarction who bear ability. Ohrn pointed out that there are more people to endure the stress of cold stimulation, cause of heart ischemic pain sensitivity is lower.

Another

results show that although the incidence of myocardial infarction in men than women more than women, but 3/4 is no symptoms of myocardial infarction and myocardial infarction, the male is 58%, that is to say, the female "atypical" myocardial infarction symptoms than men more, these reactions also considered other diseases easily the symptoms of myocardial infarction, the diagnosis rate is lower.

Although

on the whole, women’s pain tolerance is lower than male, but female pain tolerance and asymptomatic myocardial infarction rate more closely linked. According to the survey, women who have been diagnosed with myocardial infarction have a variety of different reactions when they have a heart attack, so the "pain" that needs to be realized is more complicated.

so, the clinicians should pay more attention to patients with chest pain, other symptoms, especially for female patients, these are likely to be a heart attack response; no chest pain, does not mean that doctors can reduce vigilance against heart disease, including dyspnea and leg swelling may be caused by the consequences of myocardial injury, Ohrn pointed out.

actually, through pain;
