A study by the Nagoya Institute of Technology and others found that people infected with the new coronavirus have a significantly increased risk of visiting a medical institution for heart and blood vessel diseases.

It has become clear in Japan that the risk of diseases such as the heart is increasing after infection.

A research group led by Professor Akimasa Hirata of the Nagoya Institute of Technology, based on the records of medical bills (receipts) for approximately 1.25 million people, compared the heart and blood vessels between people infected with the new coronavirus and those who were not infected. We investigated the extent to which the percentage of people who consulted a medical institution for illness or other reasons differed.



As a result, when comparing the risks of people who have no history of medical treatment for these diseases in the past year, annual medical expenses of less than 200,000 yen, and who are not considered to have serious chronic diseases, the risk is generally from the first wave to the third wave of infection. In the year until last spring,


0.14% of people had myocardial infarction within two months after being infected with the corona virus, 16.2 times more than those who were not infected,


0.79% of people with heart failure, 9.1 times more, and


venous thrombosis .

disease was 0.62%, a 26.1-fold increase, and


▽diabetes was 2.5%, a 7.7-fold increase.



The trend has not changed since then, with the

risk


of myocardial infarction increasing 10.7 times during the fourth wave since last spring and 24.6 times during the fifth wave last summer


;

▽ Diabetes was 8.4 times and 6.3 times


.

On the other hand, in the sixth wave since the beginning of this year, when Omicron stocks expanded, there was almost no difference in risk.




Professor Hirata said, ``It was reported that the risk of heart and blood vessel diseases increased in people who contracted the coronavirus overseas, but the results were similar in Japan. It is possible that the risk has decreased significantly as a result of the decrease in the ratio."
