Case 1
Which of the following is an incorrect statement regarding sildenafil citrate (Viagra)?
A. Sildenafil is a selective inhibitor of cyclic GMP-specific phosphodiesterase type 5.
B. Sildenafil results in smooth muscle relaxation, vasodilatation, and enhanced penile erection.
C. Sildenafil increases systolic and diastolic blood pressure.
D. Nitrates are contraindicated within 24 hours of using sildenafil because of the potential for a precipitous fall in blood pressure.
E. Sildenafil has no significant effect on heart rate.
F. The peak blood pressure effects of sildenafil typically occur one hour after the dose.

How would you treat this patient?
• A. Medically (drugs)
• B. Surgically (CABG or PCI)
• Given the history of diabetes, the low ejection fraction, the severity of disease, and number of lesions and occluded LAD, the patient underwent revascularization with coronary artery bypass grafting. The patient did well, and on postoperative day five, he was discharged home.
Case 2
Initial Presentation
• Chief Complaint: A 57-year-old man presented with a complaint of chest pressure on exertion.
• History of Present Illness: He reported chest pressure on exertion while mowing the lawn or walking, that radiates to his shoulders bilaterally, also accompanied by dyspnea on exertion, lasting about five minutes and relieved by rest. He denied any nausea, vomiting, or diaphoresis, and denied chest pain at rest.
• Onset: Four months ago • Duration: Four months
Case 2
Past Medical History: • Hypertension • Hypercholesterolemia
Family History: Mother had MI at young age.
Social/Occupational History: No cigarette or tobacco
use; works as carpenter.

How would you treat this patient?
• A. Medically (drugs)
• B. Surgically (CABG or PCI)
• Coronary angiography revealed a proximal 100% occlusion and an 80% mid occlusion of the left anterior descending (LAD) coronary artery; the left circumflex and right coronary artery were free of significant disease
• Following the stent procedure, the patient reported no angina with ambulation, and telemetry monitoring revealed no further premature ventricular complexes with or after activity. He was discharged on aspirin, atenolol, atorvastatin and clopidogrel for at least six months.
