Is high blood pressure actually caused by a virus?

High blood pressure, also known as hypertension, is one of the leading risk factors behind strokes, heart failure, aneurysms, and other deadly serious medical conditions. But here’s the weird thing about hypertension: we don’t actually know what causes it.

That may sound like a strange thing to say – surely, high blood pressure is the result of poor diet, or perhaps a genetic predisposition? And yes, both lifestyle choices and genetics have been shown to be correlated with hypertension, but they don’t actually cause the condition. In 95% of all cases of hypertension – a category known as essential hypertension – there is no medically recognized cause at all.

That may be about to change, thanks to researchers at the cardiology center of Beijing Chaoyang Hospital. They report the first conclusive evidence of a link between the human cytomegalovirus (HCMV) and essential hypertension. HCMV is a common virus that infects most people at some point in their lives, but it often remains completely dormant, and so shows no symptoms.

But when the virus does become activated, it can then cause high blood pressure, a condition exacerbated by all those genetic and lifestyle factors. This knowledge could have a huge impact on the fight against controlling hypertension, and by extension working to prevent strokes, serious heart conditions, and other deadly diseases. If we can create a vaccine for HCMV, it could radically cut down on the incidence of essential hypertension.

    Breathtaking, (but not literally). High BP has always been a puzzle. Why George, but not me? It may be that we are on the edge of a paradigm shift equivalent to the wonderful work of the Australian doctor who showed conclusively that chronic stomach ulcers are caused by a bacterium (Helicobacter pylorhae, if I remember correctly) and that all the poor patients needed was a three-week course of wide-spectrum anti-biotics. Definitely watch this space, Jim.

    I had the same thought Alfy. After suffering from stomach problems for 30 years (how much have I spent on antacids?) I had a miracle cure from the NHS – a course of ABs! It would be nice to find out that high blood pressure is a similar phenomenon.
