Prediction of cardiovascular death in men undergoing noninvasive evaluation for coronary artery disease
Article Abstract:
Clinical evaluation and exercise testing may be useful in predicting death due to cardiovascular events among men with heart disease. Among 2,546 men followed for an average of 2.75 years, there were 119 cardiovascular deaths and 44 non-fatal heart attacks. Thirty-four men developed congestive heart failure, 46 had coronary bypass surgery and 18 received at least one angioplasty. A history of congestive heart failure or use of the drug digoxin significantly predicted cardiovascular death. Three physiological responses measured during exercise testing - change in blood pressure, exercise capacity and ST depression - were also important predictors of cardiovascular death. Exercised-induced ST depression is a sign of inadequate blood supply to the heart. Using these indicators, 77% of the men were placed in the low risk group, 18% were placed in the moderate risk group and 6% were placed in the high risk group. Classification according to risk may prevent unnecessary medical intervention.

Relation between sodium balance and menstrual cycle symptoms in normal women
Article Abstract:
Salt retention in the last phase of the menstrual cycle does not appear to be the cause of premenstrual breast tenderness or bloating. Researchers measured blood and urinary sodium levels in 13 healthy menstruating women who consumed their usual amount of salt during one cycle, were on a salt-restricted diet on two subsequent cycles, and were allowed to add salt to food during the second salt-restricted cycle. Comparison of the three cycles revealed no differences in symptoms and no evidence of salt retention. In fact, more salt was excreted during the premenstrual period.

Coronary artery disease in young women: the menstrual cycle and other risk factors
Article Abstract:
Women with coronary artery disease may be more likely to experience chest pain at certain times during their menstrual cycle. This means that doctors may want to perform heart function tests during certain phases of the menstrual cycle.
