Warfarin (Coumadin) and dalteparin (Fragmin) are anticoagulants. Acetylsalicylic acid (aspirin), clopidogrel (Plavix), and tirofiban (Ticlid) are antiplatelet agents. Reteplase (Retavase) is a thrombolytic.
Answer to Question 2

Tobacco and smoking have been shown to increase heart rate and blood pressure because of vasoconstriction and the accumulation of plaque on the artery walls. Because of the replacement of oxygen with carbon monoxide from tobacco smoke, the heart has to work harder to supply oxygen to the organs. There is no evidence that smoking thins the blood and causes bleeding.
