ASCOT Study Shows that Diabetes, Strokes and Heart Attacks Can be Prevented

Results of the study showed that most strokes and heart attacks can be abolished or reduced by 50% by simply combining modern blood pressure lowering drugs as amlodipine and perindopril, plus effective lowering of cholesterol, which also reduced new cases of diabetes by 30%.

The success of this treatment strategy has been shown for the first time in the largest study of high blood pressure treatment ever conducted in Europe – the Anglo-Scandinavian Cardiac Outcomes Trial (ASCOT) http://www.ascotstudy.org/ – published online in The Lancet. http://www.thelancet.com/

ASCOT included more than 19,000 men and women with high blood pressure who were at a moderate risk of strokes and heart attacks. To control their blood pressure, they received either the newer drugs – a calcium antagonist, amlodipine and the ACE inhibitor, perindopril – or a traditional combination of a beta-blocker, atenolol and a diuretic. Additionally, 10,000 patients were also treated with the cholesterol lowering drug atorvastatin or a placebo. This is the only major European study to-date to combine these two treatment strategies.

Co-Chairman of the ASCOT Steering Committee, Professor Peter Sever, Professor of Clinical Pharmacology and Therapeutics, Imperial College London, International, said: “The patients treated in ASCOT were those generally seen in everyday practice. They had high blood pressure plus three additional risk factors, e.g. aged over 55, male gender, smoker. They were seen as being at moderate risk. Compared with patients receiving standard blood pressure lowering therapy of a beta-blocker and diuretic, the combination of the contemporary blood pressure lowering drugs, amlodipine and perindopril, plus effective lowering of cholesterol abolished about half the risk of strokes and heart attacks – the most important causes of death in millions of men and women with high blood pressure.”

The final results of ASCOT, showed that the combination of newer blood pressure lowering drugs reduced the risk of strokes by about 25%, coronaries by 15%, cardiovascular deaths by 25% and new cases of diabetes by 30% compared with the standard treatment.

The addition of the cholesterol lowering drug, atorvastatin, still further reduced the remaining risk irrespective of the patient’s original cholesterol level. Indeed, the ASCOT patients only had average or below average levels of cholesterol at the outset of the study.

Commenting on the importance of these results, Co-Chairman of the study, Professor Bjorn Dahlof, Associate Professor in the Department of Medicine at Sahlgrenska University Hospital/Ostra, said: “High blood pressure is a major public health problem. Despite the availability of effective blood pressure lowering drugs, many people who are being treated still suffer strokes, heart attacks and other related diseases, such as diabetes. Now, the evidence from ASCOT offers us a simple and effective combination of treatments which both control the blood pressure and lower cholesterol to more effectively reduce this risk. This is very important news for patients and their physicians.”

Following the study, the investigators believe that international recommendations for managing high blood pressure may need to be reviewed. Additionally, they suggest that most patients with hypertension should also be considered for a cholesterol lowering drug.

However, they emphasise that patients taking beta-blockers and diuretics should not discontinue their treatment. The Co-Chairmen of the study, Professors Sever and Dahlof concluded: “Diuretics and beta-blockers are an effective and proven combination for lowering blood pressure and its associated risks. What ASCOT has shown is that for many patients the combination of newer drugs may be an even better option. Patients should discuss the implications of ASCOT with their physicians before any modification of treatment is considered.”
