Gender differences in attitudes toward alcohol, tobacco, and other drugs.

A number of differences exist between men and women in use patterns and risk factors for substance abuse. In recent years these differences have received increased attention; however, gender-related attitudes toward substance abuse need additional study. This study examines gender-related differences in beliefs about the causes of the abuse of alcohol, tobacco, and other drugs; the power of various substances of abuse; the prevalence of substance use; and the effectiveness of various interventions. Women were more likely to attribute causality to biological or environmental factors, to perceive drugs as more powerful, to perceive a higher incidence of substance abuse, and to believe prevention and treatment were more effective. Therefore, prevention, assessment, and treatment programs should be designed differently for women than for men.

Exercise stress testing in the patient with coronary artery disease. Part II.

Cardiac exercise stress testing has both diagnostic and prognostic implications. ECG changes, hemodynamic responses, and symptoms during exercise are clues to the functional capacity, severity of coronary artery disease, and probability of future coronary events. The time and workload required for a positive response to exercise and the length of time the ECG changes persist during recovery are indicators of the degree of coronary disease and are useful in predicting future coronary events.
