AFP - Treating hypertension prolongs life expectancy in the long term, according to a clinical trial in the United States whose results were published Tuesday in the Journal of the American Medical Association (JAMA).
The anti-hypertensives had already shown their ability to reduce cardiovascular events in different studies but there was no previously data on gains in life expectancy, say the authors of this research.
The clinical trial was conducted for four and a half years from March 1985 to January 1988, with 4736 participants aged 60 years and with all of hypertension. Follow-up period lasted 22 years.
Half the group was treated with antihypertensive chlorthalidone and half with placebo.
At the end of the trial, doctors have recommended that all participants taking medication against hypertension.
At the end of follow-up period, 60.2% of participants, 2,851 people had died.
But the researchers found that the subjects during the four and a half years of the trial against hypertension generally lived longer than the control group.
The gain in life expectancy is 158 days for those who died of heart attack and 105 days for participants who died of all causes of death.
Thus the gain in life expectancy for those who died following a heart disease is about one day per month of treatment against hypertension.
This study was conducted by Dr. John Kostis, Faculty of Medicine, Robert Wood Johnson in New Brunswick (New Jersey, is).
