Obviously, high blood pressure is not a covert agent / mercenary from feudal Japan. But high blood pressure is a silent killer, something they have in common with those feudal Japanese assassins.
In Kalehoff, and Oparil, (2020) article which was aptly titled “The Story of the Silent Killer”, they said that, Hypertension (high blood pressure) is the leading risk factor for death and disability globally. Worldwide, it contributes to over 10.4 million deaths every year (Kalehoff & Oparil, 2020).
In South Africa, more than 1 in 3 adults live with high blood pressure, and it is responsible for 1 in every 2 strokes and 2 in every 5 heart attacks (The heart foundation).
It’s at this part that you may be wondering, but where the ‘silent’ part comes from?
Well, unless you have a special machine, which was only invented in the last 100 years of the 4000+ of studying this ‘hard pulse’, it’s impossible to know if you have high blood pressure (Kalehoff & Oparil, 2020). It shows no symptoms and yet it strikes without warning (Kalehoff & Oparil, 2020).
This is one of the reasons why between 44% to 93% of people with hypertension in sub-Saharan countries like South Africa are unaware of their status (Echouffo-Tcheugui et al., 2015).
