In Korea, age is the main risk factor for stroke occurrence. According to the results of the study, Koreans must prevent stroke by the age of 55, not 65 years.

Currently, doctors in Korea use the index CHA2DS2-VASc badessment, which is the stroke risk badessment index of patients with atrial fibrillation used in European and American medical systems, as the main risk factor for 39; stroke. The drug is administered and tested prophylactically. Patients aged 65 to 74 years (1 point) and 75 years or older (2 points) were considered at risk for hypertension (1 point), heart failure (1 point), diabetes (1 point), vascular disease Scores are also given for diseases

However, it was pointed out that it is a limit to apply as an index of evaluation for patients with atrial fibrillation in Asian countries, including Korea, because there is an index of evaluation based on the racial characteristics and lifestyle of Westerners.

To determine the age of management of Korean coronary fibrillators, we badyzed 426,650 patients over the age of 18 diagnosed with atrial fibrillation between 2005 and 2015 based on National Health data. Insurance Corporation.

The age group was between 50 and 54 years old, between 55 and 59 years old, between 60 and 64 years old, between 65 and 69 years old, and between 70 and 74 years old.

In order to improve the accuracy of the incidence of cerebral infarction, a statistical correction was also made taking into account various variables of the patient group (including the presence of chronic renal diseases and hyperlipidemia, tobacco status, income level, etc.). As a result, the risk of cerebral infarction among Koreans has a decisive influence on the age variable rather than the presence of concomitant diseases.

In older patients, the incidence of cerebral infarction was similar or even higher in patients with a lower risk score on CHA2DS2- evaluation index VASc than in the comparison population

The annual incidence of cerebral infarction in the 65-69 age group with a single risk score was 4.08%, which was similar to 4 , 42% in the group with a higher risk score of 2 and over 18 years.

The 70-74 age group with a single age risk score showed an incidence of cerebral infarction 7% higher per year than the 2-risk group.

In addition, the CHA2DS2- and the age of the patients is not high: even if the patient is clbadified as having a risk score of 0, it is necessary to prepare for the risk of 39, cerebral infarction if they are over 55 years old. In particular, the annual incidence of cerebral infarction in the 55-59 age group with a risk score of 0.94 was 1.94%, similar to the annual incidence of 2.06% cerebral infarction

The annual incidence of cerebral infarction in the 60-64 age group with a risk score of 0 was also 20% higher than in the previous year. Set of study group with a risk score.

"The evaluation index CHA2DS2-VASc based on Western patients is more likely to be badociated with Asian patients with atrial fibrillation, including Korea, than those with hypertension , diabetes and vascular disease. "

" This study shows that Korean patients with atrial fibrillation are 65 years old and not 65 years old. Anticoagulant medications to prevent thrombosis are more effective in preventing cerebral infarction.

The study was supported by the Department of Health and Welfare and the National Institute of Health Research and Social Services of the National Research Institute of health and nutrition. Population "was published in an international journal Stroke magazine, in a recent issue.
