An important habit to prevent sudden death from heart disease

2021.03.01

“Cardiac disease” is the second most common cause of death in Japan after cancer. The most
common form is ischemic heart diseases such as acute myocardial infarction. As a result of
advanced arteriosclerosis, the aorta that supplies blood to the heart becomes narrowed or
clogged, resulting in insufficient blood flow.
It is well known that exercise is beneficial in preventing heart disease such as myocardial
infarction. Not only that, exercise habits also appear to reduce the risk of death after a
myocardial infarction.

Weekly energy consumption affects prognosis

This is a study conducted by Kim Wad Hansen and colleagues at the Bispebjerg Frederiksbei
University Hospital in Denmark.
From 10 European cohorts (the population to be observed, here 1,495,254), 28,140 people who
had an acute myocardial infarction during follow-up were included.
Depending on the total energy consumption (physical activity level) per week, (1) tend to sit
(less than 7 MET / hour), (2) low (7 to 16 MET / hour), (3) medium (16.1 to 32 MET / hour), and
(4) high (32 MET / hour). When we divided the subjects into four groups, and investigated the
relationship to the risk of death in the acute phase of myocardial infarction, those who
consumed more total energy per week than those who tend to sit down. We found that the
group with higher levels of physical activity had a lower risk of death in the acute phase.

People who tend to sit down have more instant deaths

Of the 28,140 people analyzed, 17.7%, or 4,976, died within 28 days of onset. In addition, 3,101
(62.3%) of them died instantly within 1 hour of onset.
Looking at this by total energy expenditure over the previous week, it was suggested that
moderate to high levels of physical activity reduce the risk of instantaneous death and death
within 28 days, as follows:
● People with higher physical activity levels have a 45% lower risk of instantaneous death after
an acute myocardial infarction and a 28% lower risk of death within 28 days than those who
tend to sit.
● People with moderate physical activity levels have a 33% lower risk of instantaneous death
after an acute myocardial infarction and a 36% lower risk within 28 days than those who tend to
sit.

Daily bathing also helps prevent heart disease

The study shows that regular exercise habits not only help prevent heart disease such as acute
myocardial infarction, but also reduce the risk of death after onset. Sudden death is often seen
as unpredictable (and is unpredictable), but increasing physical activity, rather than maintaining
za sedentary lifestyle, reduces the risk of sudden death.
In addition, domestic studies have shown that daily bathing habits (bathing in a bathtub) reduce
the risk of developing ischemic heart disease and stroke. In this study, people taking a bath
“almost every day” had a 35% lower risk of developing ischemic heart disease than those in the
“less than twice a week” group, 46% for cerebral hemorrhage, and 23% for stroke. It seems that
a decrease in percentage was observed.
Maintain a habit of moving your body as much as possible, and take a bath every day. These
daily habits help prevent arteriosclerosis and prevent dangerous sudden death.
