Predicting Heart Disease Risks in Families

All of our followup studies over 20 plus years have shown that brothers and sisters of  people who were hospitalized with early onset coronary disease have a risk that is much higher than the general population. The risk is particularly high in brothers.

Happiness As a Trait Protects Against 
10 Year Risk of Heart Attack
Using the General Well Being Schedule, a 26 item questionnaire, we have consistently found that people who have a trait that lends more toward happiness may has as much as a 50% lower rate of heart attacks, independent of all other risk factors.

Women Have "Sticker" Platelets than Men: 
Still Achieve Benefit with Aspirin
Some trials suggest that women may not accrue the same heart protective benefits as men do from low-dose aspirin therapy used in primary prevention, although they do get a benefit in terms of stroke reduction. Our results showed that  women’s platelets were significantly more reactive at baseline, in other words, stickier and more likely to form a clot. Aspirin still produced an effect on this.  Click on the photo for the original paper that give the full scientific details.


Diabetes Increases the Risk for Heart Disease 
More in Women than in Men
Controversy exists about the coronary heart disease risk conveyed by diabetes in women. We investigated sex differences in heart disease rates by diabetes status in  healthy individuals in GeneSTAR. Although heart disease rates were lower among most women versus men, diabetic women had disease rates that were as high as mens.  Diabetes is more prevalent in African Americans, especially in African American women. Click on the photo for the original paper that give the full scientific details


Manual Dexterity in Healthy People and 
Silent Early Findings on Brain MRI
We proposed that manual dexterity would be affected by silent white matter intensities on brain MRI, representing very early small vessel disease.. Manual dexterity is controlled by many areas of the brain, including those that affect vision, motor function, anticipation, precision, and planning.  We found thatminor deficits in many brain areas resulted in lower levels of manual dexterity using the pegboard test..Click on the photo for the original paper that give the full scientific details


Dark Chocolate May be Good 
for Your Platelets
Healthy adults (1535) in the GeneTAR aspirin study were told not to eat chocolate for the 2 weeks they were taking aspirin. Almost 10% (141) were unable to do this and truthfully reported their chocolate intake over the two weeks. Despite being otherwise identical to other participants, the people who ate had less sticky platelets. We concluded that small amounts of dark chocolate without a lot of sugar conveyed some benefit to people.Click on the photo for the original paper that give the full scientific details
