  Hypertension Drugs Found to Cut Risk of Stroke

  Australian doctors declared Monday that a cocktail of simpleantihypertensive drugs can lower the risk of patients suffering a repeat strokeby more than a third. This is the result of their research. The research,presented at a medical conference in Italy over the weekend, has been valuedhighly as a major breakthrough in stroke prevention.

  Strokes kill 5 million people a year, and more than 15 millionsuffer non-fatal strokes that often leave them with useless limbs, slurredspeech and other serious disabilities. One in five stroke survivors goes on tohave a second, often fatal, stroke within five years of the first.

  An international six-year study of 6,100 patients directed fromSydney University found that by taking two blood pressure-lowering drugs, therisk of secondary strokes can be reduced by up to 40 per cent. Even taking oneof the commonly available drugs can cut the risk by a third, the study said.The drugs are the diuretic indapamide and the ACE inhibitor1 perindopril,better known by its brand name Coversyl. The combination was effective even inpatients who did not have high blood pressure, the researchers said. They evenfound that the risk of another stroke could be cut by three quarters among theone-in-ten patients who had suffered a cerebral hemorrhage, the worst type ofstroke, where there is direct bleeding into the brain.

  Stephen McMahon, who presented the research at the Milan congress ofthe European Society of Hypertension, said about 50 million people were alivewho had suffered at least one stroke. “If most of those patients were able toget access to2 this treatment, it would result in3 maybe the avoidance of halfa million strokes a year,” the professor told Australia’s ABC Radio.

  McMahon said doctors had long known that lowering the blood pressureof those with hypertension could help prevent strokes.” What we have shown forthe first time is that it does not really matter what your blood pressure is4;if you havehad a stroke, then lowering blood pressure will produce large benefits, tobegin with5—even for people whose blood pressure is average or below average,”he said.

  McMahon said the Milan gathering had heralded the research as a “majorbreakthrough in the care of patients with strokes — perhaps thebiggest step forward that we have made in the last couple of decades”.
