Stratification of morbidity and mortality outcome by preoperative risk factors in coronary artery bypass patients: a clinical severity score

Article Abstract:

A clinical model based on the severity of illness of patients undergoing a coronary artery bypass operation may be better at predicting an outcome of death or complications than methods currently used. Patients who were older or who had a previous emergency procedure, high blood creatinine levels, severe dysfunction of the left ventricle of the heart, insufficiency in the mitral valve, a hematocrit of 0.34, chronic lung disease or previous vascular surgery were more likely to die after coronary artery bypass surgery than were other patients. Individuals with diabetes, a high body weight (65 kg or more), aortic stenosis or cerebrovascular disease also had a higher risk of death than other individuals. Mathematical equations waiting the different factors were developed to classify patients undergoing coronary artery bypass in different risk categories. Patients were assigned risk-factor values of one to six points, and those with more points had a higher risk of death or complications such as infection, kidney failure or the need for artificial assistance.

N-terminal fragment of the prohormone brain-type natriuretic peptide (NT-proBNP), cardiovascular events, and mortality in patients with stable coronary heart disease

Article Abstract:

The association of plasma levels of amino terminal fragment of the prohormone brain-type natriuretic peptide (NT-proBNP) in predicting cardiovascular events or death independent of other available prognostic tests is described. The results have shown that elevated levels of NT-proBNP have predicted cardiovascular morbidity and mortality and have identified at-risk individuals even in the absence of systolic or diastolic dysfunction by echocardiography.

Mortality and malnutrition among populations living in South Darfur, Sudan: Results of 3 surveys, September 2004

Article Abstract:

A rapid epidemiological assessment of mortality and nutritional status at 3 sites in South Darfur for relief efforts is done. The results of the assessment provide epidemiological evidence of the high rates of mortality and malnutrition among the displaced population in South Darfur.
