Could Headache And Fainting Be Due To Actos?

My husband, 56 yrs old just passed out, woke up sweating profusely, and didn t know what happened. THey took him to the doctor and they said he has a bundle blockage in hes heart. He is okay now but he is supposed to follow up with his doctor when he gets back home. My question is(he is also type 2 diabetic), about a month ago he started taking Actos. Since then he has had a constant headache. Could the headache and passing out be from this new drug?
