It is generally believed that exercise-induced hypotension is the result of severe left-main or triple-vessel disease. Since this is not invariably so, and since most studies were performed in male populations, this study was done to determine the frequency of, and the significance of, exercise-induced hypotension in a more general population. ⋯ This study identified two patterns of exercise-induced hypotension. Early, almost always due to severe coronary artery disease, and late, six times more common than early in which only half were due to coronary artery disease. Causes of a late hypotensive response to exercise that were not due to severe coronary artery disease included valvular heart disease, orthostatic hypotension, cardiomyopathy, idiopathic causes, and drugs. Drugs that contributed to a late exercise-induced hypotension response were diuretics, vasodilators, and negative inotropic agents.

Several studies have demonstrated that surrogate decision makers often are unable to use substituted judgment when asked to make decisions for incompetent patients. This study further explored this question, using a relatively young, healthy sample of 50 patient/surrogate pairs. ⋯ The high rate of discrepant decisions underscores the importance of effective patient-surrogate communication before medical decision-making incompetence occurs. The potential of increasing patient-surrogate agreement on difficult medical decisions by educational interventions should be explored.

To survey internal medicine residency program directors regarding interactions between their residents and pharmaceutical company (PC) representatives (PCRs) a questionnaire was sent to the directors of all Accreditation Council for Graduate Medical Education-approved internal medicine residency programs. The survey included 444 program directors, of whom 272 (61.16%) responded. The majority of program directors, 228 (83.8%), allowed PCRs to meet with residents during working hours and 241 (88.6%) permitted PC sponsorship of conferences. ⋯ Most program directors reported that alternate funds for conferences were available if PC support was withdrawn. "Unethical" marketing activities were observed by 14.3% of program directors and 37.5% reported that residents had participated in PC-sponsored trips during the 3 years prior to the survey. At the time of this survey, only 35.3% of programs had developed formal policies regulating PCR activities and 25.7% provided residents with formal instruction on marketing issues. Knowledge of the current extent of PCR interactions with residents may be helpful to program directors in developing policies regulating PC-marketing activities.
