An important new study reports that doctors have a new drug. This drug is called TP

Doctors may not be able to stop many heart attacks. An important new study reports that doctors have a new drug. This drug is called TPA. It may be better than any other heart drug. Many doctors now use a drug called streptokinase. But this drug sometimes causes problems for patients. It can even cause bleeding in the brain. Some doctors do not use streptokinase. Streptokinase can save about one third of the people with heart attacks. But TPA will save about two thirds. This means many people. About 1.5 million Americans have heart attacks every year. One reason TPA can help more people is because of time. This new drug is easier and faster to use. It will give doctors more time in hospitals. Then they can study the problem well. People with heart problems can also keep some TPA at home. When a heart attack starts, they can take some TPA right away. Then they will have time to get to the hospital. This is important because about 860,000 people in the United States die before they get to the hospital. According to the passage, which of the following about TPA is NOT true? A. It will be tested on many more people with heart attacks. B. It has found wide application in many hospitals. C. It will cause less problems than streptokinase does. D. It is not only easier and faster to use but also a lot safer.
