Cardiovascular risk factors have expanded to include personality and other psychological characteristics. Negative affect (NA) has a longstanding history in cardiovascular health, but the path by which NA leads to cardiovascular disease (CVD) is yet to be defined. The following study examined the relationship of high NA and low extroversion (EX) with physiological cardiovascular markers in a sample of non-medical, professional adults. Our results indicated that individuals high in NA and low in EX displayed a significantly lower platelet count and a significantly higher mean platelet volume. Individuals high in NA displayed a significantly lower cholesterol risk ratio, while individuals high in EX displayed significantly higher platelet counts. Personality was not significantly related to blood pressure, high or low density lipoproteins. Understanding the relationships among psychological variables and physiological markers will help clinical researchers design interventions that reduce the likelihood of CVD.
