High potency statins linked to better outcome following a myocardial infarction


A study looking at the data of thousands of patients who suffered myocardial infarctions has suggested treatment with high-potency statins offers a significantly improved chance of survival compared to those taking normal statins.

The study, led by the University of Dundee, also found a combination of statins and the drug Ezetimibe ( Zetia ) showed no improved survival rate, although researchers caution this finding needs further testing.

Ezetimibe has been shown to be very effective at lowering cholesterol but we do not know its effect on survival. The key question really is whether it is better than statins, especially high potency statins such as Rosuvastatin ( Crestor ) or Atorvastatin ( Lipitor ).

The study has shown that patients who switched from normal statin treatment to high potency statins lived longer.
'Those who had Ezetimibe added did not appear to have a better outcome.

So for the moment the data supports the use of high potency statins.

Results of the study have been published in the journal Heart.

Data for the study was drawn from the UK's Clinical Practice Research Datalink. Researchers looked at the data for patients who had survived 30 days after their first myocardial infarction, who had not received prior statin or Ezetimibe therapy, and who were started on a statin within that period of their attack.

The data of 9597 patients was used. 6990 of those were treated with Simvastatin ( Zocor ), 1883 had switched to a more potent statin, and 724 were given an Ezetimibe / statin combination.

Data for the group was analysed for an average 3.2 years from the start point of their first myocardial infarction. During that time there were 1134 deaths.

The results showed that patients who switched to a high-potency statin had a 28% lower risk of death compared to those who received Simvastatin. There was no observed benefit of adding Ezetimibe. ( Xagena )
