Hypertension: Uncontrolled and Taking Over the World

This news release in Science Daily is of special interest to transplant patients because we are very susceptible to hypertension (high blood pressure) due to the side effects of drugs such as cyclosporine, tacrolimus, rapamune and prednisone. Because of this we must take blood pressure medication and reduce high-salt and high-fat foods in our diet. Yet this news release suggests many people do not comply with their treatment and stop taking their hypertension drugs when blood pressure levels fall. Left untreated, high blood pressure can lead to stroke, kidney failure, cardiovascular disease and death.

“Lifestyle factors, such as physical inactivity, a salt-rich diet with high processed and fatty foods, and alcohol and tobacco use, are at the heart of this increased disease burden, which is spreading at an alarming rate from developed countries to emerging economies, such as India and China.”

The Lancet
Science Daily — The biggest problem for controlling hypertension (high blood pressure) is compliance with treatment, says an editorial in the cardiology special edition of the Lancet.

The editorial, which ties in with a seminar on hypertension, says: “Despite very effective and cost-effective treatments, target blood pressure levels are very rarely reached, even in countries where cost of medication is not an issue. Many patients still believe that hypertension is a disease that can be cured, and stop or reduce medication when blood pressure levels fall.”

The risk of becoming hypertensive for a person in a developed country exceeds a “staggering” 90%, and the increasingly common combination and interaction of hypertension with obesity, diabetes and hyperlipidaemia, if left untreated for too long, leads to cardiovascular disease, stroke, renal failure and death.

The disease burden of hypertension is expected to massively increase in the coming years. In 2000, the estimated number of adults living with high blood pressure was 972 million; this is expected to increase to 1.56 billion by 2025. The Editorial says: “Lifestyle factors, such as physical inactivity, a salt-rich diet with high processed and fatty foods, and alcohol and tobacco use, are at the heart of this increased disease burden, which is spreading at an alarming rate from developed countries to emerging economies, such as India and China.”

The editorial concludes: “Physicians need to convey the message that hypertension is the first, and easily measurable, irreversible sign that many organs in the body are under attack. Perhaps this message will make people think more carefully about the consequences of an unhealthy lifestyle and give preventative measures a real chance.”
