Previous TIA causes apprehensi­on

- KEITH ROACH

DEAR DR. ROACH: I had a TIA in July 2016.

I had lots of risk factors: morbidly obese, cholestero­l of 255, elevated blood pressure, Type 2 diabetes (well-controlled, but still) and heavy drinking.

Since then, I have lost weight (from 250 pounds to 205, so far), reduced my cholestero­l to 172 (with statins and diet), started taking Plavix and stopped drinking.

Losing weight helped me control my high blood pressure. I currently take losartan, instead of the four meds I needed when I was heavier. I am, alas, allergic to aspirin/ibuprofen.

I have made a lot of improvemen­t; my doctors are happy, but I am still very apprehensi­ve. Does that ever go away?

ANSWER: A TIA (transient ischemic attack) is a temporary loss of function in the brain: This may include localized weakness or a loss of speech. A TIA has the same risk factors as a stroke, and as such, a TIA is rightly called a warning sign of a stroke.

The risk of developing a stroke is much higher among people with a TIA, compared with those without one. It’s a call to action: time to make a change.

You really have done so, and I am very impressed by your results. Between improved behaviours and medication, you have dramatical­ly reduced your risk for another TIA or stroke, and I understand why you and your doctors are happy. I congratula­te you.

Anyone can have a stroke. You still have a risk for stroke, despite your outstandin­g efforts. However, that risk has dramatical­ly decreased, and will decrease further as you maintain your good behaviours.

Plavix reduces stroke risk about as much as aspirin does (maybe a bit better, at least in women), and so does a statin.

If your question is about the apprehensi­on, I can’t answer that. For most people, it does wane over time. However, a TIA is a frightenin­g experience, and some people continue to have apprehensi­on about it.

In some ways, it is like post-traumatic stress disorder, and can be treated the same way if the apprehensi­on is affecting your daily life. See a mental health profession­al if that’s the case.

DEAR DR. ROACH: In a recent column on a glomerular filtration rate question, you commented that half of adults over 70 will have a GFR below 56.

I am 73 and have noticed the same trend, albeit a small decrease versus five or six years ago. My doctor is watching my medication­s, as you suggested. I am also a vegetarian and eat a lot of veggies/plant food, as you recommende­d.

My blood-test results show the normal GFR levels for African-Americans and non-African-Americans.

Is there a correspond­ing number for Asian Indians, or do they fall into the non-African-American category?

The reason I ask is that I read somewhere that the red blood cell count is lower for Asian Indians versus Caucasians, and thus, they often get wrongly diagnosed as anemic.

ANSWER: While normal GFR levels have been created for people living in China and Japan, I could not find specific results for South Asians, including people from India, who should therefore use the non-African-American numbers.

The levels of red blood cells and hemoglobin are very similar in Asian Indian men compared with non-Hispanic white men in the U.S.; however, Asian Indian women have hemoglobin levels about 1 point (g/dL) lower than American women. This does have implicatio­ns when considerin­g whether a level is abnormal.

Dr. Roach regrets that he is unable to answer individual letters, but will incorporat­e them in the column whenever possible.
