Lipitor, which is also known as atorvastatin, is a medication that is primarily used to treat high cholesterol levels in the blood. It works by reducing the production of cholesterol in the liver and increasing the liver's ability to remove cholesterol that is already present in the blood [1].

There is some evidence to suggest that Lipitor may have an unexpected benefit for patients with chronic stable angina, a condition characterized by chest pain or discomfort caused by reduced blood flow to the heart [2]. According to a study published in the Journal of the American College of Cardiology, patients with chronic stable angina who took Lipitor experienced a significant reduction in the number of episodes of chest pain they experienced, as well as a reduction in the need for medication to treat their angina [3].

However, there is no evidence to suggest that Lipitor can be used to treat high heart rate specifically. While high heart rate can be a symptom of certain conditions that Lipitor may be used to treat, such as high blood pressure or coronary artery disease, Lipitor is not indicated for the treatment of high heart rate [1].

In conclusion, while Lipitor may have some unexpected benefits for patients with chronic stable angina, there is no evidence to suggest that it can be used to treat high heart rate specifically. Patients who are experiencing high heart rate should consult with their healthcare provider to determine the underlying cause of their symptoms and the most appropriate course of treatment.
