Background: Many patients present to emergency departments with chest pain but little is known about this population and the safest, most efficient testing strategies.

Aims: We assessed clinical risk stratification of all patients with chest pain and, on a subset, utility of high sensitivity troponin at 4 and 6 hours after pain onset in aiding disposition decisions.

The association between cerium status and risk of first acute myocardial infarction (AMI) was examined in a case-control study in 10 centres from Europe and Israel. Cerium in toenails was assessed by neutron activation analysis in 684 cases and 724 controls aged 70 years or younger. Mean concentrations of cerium were 186 and 173 μg/kg in cases and controls,

Hazardous chemicals escape to the environment by a number of natural and/or anthropogenic activities and may cause adverse effects on human health and the environment. Increased combustion of fossil fuels in the last century is responsible for the progressive change in the atmospheric composition. Air pollutants, such as carbon monoxide (CO), sulfur dioxide (SO2), nitrogen oxides (NOx),

Environmental factors are considered key determinants of cardiovascular disease. Although lifestyle choices such as smoking, diet, and exercise are viewed as major environmental influences, the contribution of pollutants and environmental chemicals is less clear. Accumulating evidence suggests that exposure to pollutants and chemicals could elevate the risk of cardiovascular disease. Many epidemiological studies report that exposure to fine particles present in ambient air is associated with an increase in cardiovascular mortality.

We conducted a cross-sectional analysis of individuals 45–79 years old in the National Health and Nutrition Examination Survey III (1988–1994) (NHANES III). Myocardial infarction was determined by electrocardiogram (ECG). Our sample included 4912 participants, which when weighted represented 52,234,055 Americans. We performed adjusted logistic regressions with the Framingham risk score, pack-years of smoking, race-ethnicity, and family history of heart attack,

Objective— Metal constituents of tobacco have long been suspected to contribute to cardiovascular diseases. In this study, we determined the serum concentrations of aluminum, cadmium (Cd), cobalt, copper, iron, manganese, nickel, lead, strontium (Sr), and zinc of young nonsmokers, passive smokers, and smokers.

Methods and Results— Cd and Sr were found to be significantly increased in smokers compared with nonsmokers.

Cadmium exposure has been associated with increased all-cause, cancer, and cardiovascular disease mortality. However, studies investigating this association have included participants with considerably higher levels of cadmium than those found in the general population.
We aimed to evaluate the association of creatinine-corrected urinary cadmium levels with all-cause and cause-specific mortality in the U.S.

Abstract: PurposeEpidemiologic data suggest an association between cadmium exposure and cardiovascular disease though the underlying mechanisms remain unclear. This study explored the hypothesis that cadmium exposure is associated with elevated C-reactive protein (CRP) and fibrinogen, two risk factors for developing cardiovascular disease.MethodsThe current study investigated associations between urinary cadmium and the prevalence of elevated blood CRP (≥2.2mg/L) and fibrinogen (≥10.35μmol/L) using data from a sample of 6497 participants aged 40–79 in the Third National Health and Nutrition Examination Survey.
