Heat may raise risks of heart attacks for some meds users

Staying out of the heat — especially in Arizona this time of year — is always good advice.

But new research in the journal Nature Cardiovascular Research shows it might be especially vital for people who use certain cardiovascular medications.

The 14-year study in Augsburg, Germany, shows patients taking anti-platelets, beta-blockers or both had a significantly higher risk of non-fatal heart attacks on hot-weather days.

Further research is needed to confirm the results, since the authors could not rule out the possibility that such patients are simply sicker and thus more at risk.

Arguing against that wrinkle is the fact that the link between meds and heart attacks was stronger among people younger than 60, who were also less likely to have pre-existing coronary heart diseases.
