OBJECTIVE The authors' goal was to determine whether sertraline attenuates the increased platelet activation seen among depressed patients. METHOD They tested 21 otherwise healthy patients with untreated major depressive episode who were 25-52 years old and 21 age- and sex-matched comparison subjects. Patients received 6 weeks of sertraline treatment, and(More)
OBJECTIVE This study was undertaken to determine the relationship between heightened reactivity of blood pressure (BP) during stress and 5-year changes in blood pressure and hypertensive status, using the CARDIA study. METHOD A total of 3364 participants (910 white men, 909 white women, 678 black men, and 867 black women), initially 20 to 32 years old and(More)
Although there has been extensive research attempting to identify psychophysiologic mechanisms linking psychological events and behavior patterns with risk for coronary heart disease, these are important potential mechanisms that remain largely unexplored. One of these mechanisms is thrombosis, which is widely recognized as the precipitant of acute coronary(More)
Previous studies have demonstrated a potential relationship between psychological stress and platelet activation, which may serve as a link between stress and myocardial infarction (MI). However, the possibility that personality traits associated with coronary heart disease may affect platelet activation has not been adequately investigated. The effect of a(More)
BACKGROUND Hostility has been shown to predict both the development and manifestation of coronary disease. Examining the inter-relation of dietary intake of fish and of polyunsaturated (n-3 and n-6) essential fatty acids with hostility may provide additional insights into the cardioprotective effect of dietary fish and polyunsaturated fatty acids.

OBJECTIVE To determine whether Potential for Hostility is related to platelet activation (PA) among patients with coronary heart disease (CHD) and healthy controls. Increased PA has been associated with adverse secondary events after myocardial infarction or coronary angioplasty. METHODS We tested 32 CHD patients and 23 healthy men and women, aged 45 to(More)
This study sought to determine whether depressive symptoms and/or platelet serotonin receptor (5HT2A) density are associated with increased platelet activation (PA) found among smokers. Flow cytometric detection of PA was used to study 36 smokers and 16 nonsmokers, aged 18 to 48 years. Subjects were tested at baseline and after either smoking 2 cigarettes(More)
OBJECTIVE To determine whether urinary cyclic GMP (cGMP), which mediates the actions of the vasodilators nitric oxide and atrial natriuretic factor, is inversely related to blood pressure (BP) reactivity. In previous work, we found that urinary cGMP was inversely related to diastolic BP, but cGMP levels were higher among individuals presumed to have(More)
