Glycoprotein IIb/IIIa inhibitors (abciximab generic glucophage xr 500mg overnight delivery, eptifibatide, and tirofiban) block the final common pathway of platelet aggregation and have been shown to reduce the risk of death, MI, and revascularization procedures. The use of cardiac catheterization in the setting of non–ST segment acute coronary syndromes has been shown to reduce the length of stay with initial hospitalization and the need for rehospi- talization. In a recent trial, an invasive strategy combined with antiplatelet therapy was shown to reduce the rate of death or MI when compared with a noninvasive strategy. Current recommendations of the American College of Cardiology/American Heart Association include catheterization and revascularization of high-risk patients (defined by prior MI, left ventricular dysfunction, widespread ECG changes, or recurrent ischemia). Thrombolytics have been studied in the setting of acute coronary syndromes without ST segment elevation or bundle branch block and have been found to be deleterious, so they are contraindicated in this setting. A previously healthy 52-year-old man presents with complaints of intermittent substernal chest dis- comfort. The symptoms occur with exercise, and they are not relieved by rest. You determine that the patient has an intermediate pretest probability of having significant coronary artery disease, and you elect to have him undergo exercise ECG testing to further evaluate his symptoms. Which of the following findings would be most highly suggestive of significant ischemic heart disease (IHD) on exercise ECG testing? Exercise-induced falls in blood pressure or the development of an exercise-induced S3 heart sound are strongly suggestive of ischemic left ventricular dysfunction. Specific exercise-induced ECG changes include changes ≥ 1 mm horizontal or downward-sloping ST segment depression or elevation during or after exer- cise. Exercise-induced changes in lead V5 are most reliable for the diagnosis of IHD. A 56-year-old man with hypertension presents to your clinic for a routine health maintenance visit. He is asymptomatic and takes only hydrochlorothiazide. His total cho- lesterol level is 190 mg/dl, and his high-density liproprotein (HDL) cholesterol level is 36 mg/dl. He tells you he is concerned about IHD and that he has read about new methods to detect early disease, including CT imaging.

Stress urinary incontinence and erectile dysfunc- tion are frequent in those undergoing radical prostatectomy buy discount glucophage xr 500mg on line. In fact, most patients under- going the procedure are rendered impotent. The rates of both of these adverse effects are higher in patients undergoing radical prostatectomy than in those who receive external- beam radiation therapy. However, erectile dysfunction still occurs in the majority of 24 BOARD REVIEW patients who undergo radiation therapy. In addition, a decline in bowel function is more common in patients receiving external-beam radiation therapy than in those who under- go radical prostatectomy. A 60-year-old man comes to you because he has heard there is a blood test for prostate cancer that he would like to be given. You explain that the decision to undergo screening for prostate cancer is not as simple as it might seem, and you want him to understand the screening process. Which of the following statements should be included in your explanation to this patient? Although one-time or repeated screening and aggressive treatment of prostate cancer may save lives and avert future cancer-related illness, we do not yet know this for certain B. The available tests for prostate cancer (PSA and DRE) will sometimes indicate cancer when there is none (false positives) and will sometimes fail to detect cancer when it is present (false negatives) C. A positive result on PSA or DRE will suggest that he should undergo invasive testing, such as transrectal ultrasound and prostate biopsy D. Should he be found to have prostate cancer, he will want to consider aggressive therapy, and there is a small but finite risk of early death and a significant risk of chronic illness, particularly with regard to sex- ual and urinary function E. All of the above Key Concept/Objective: To understand the uncertainty surrounding screening for prostate cancer, and be able to communicate that uncertainty intelligibly to patients There is disagreement as to whether men should be screened for prostate cancer. It is important to understand that it is not yet known whether screening for prostate cancer will help men live longer and that significant morbidity and mortality have been associ- ated with the diagnostic and therapeutic procedures involved in screening. These facts should be conveyed to the patient to help him make an informed decision.
