Instructions: Indicate the presence of numerical data in the abstract (whether numerical data plays a key role in medical records), solely using the information from the abstract.
Input: Abstract: Acute myocardial infarction occurred in a 25-year-old woman. Coronary angiography performed one month after the acute illness was normal. An ergonovine test was negative. The patient's acute myocardial infarction most probably was induced by the use of oral contraceptives in combination with heavy smoking. Oral contraceptives, with their known influence on the blood coagulation system, must be considered a risk factor in precipitating coronary artery disease. 
Question: Does the abstract contain any numerical data?
Output:
Yes
