What main etiology would we be concerned about with pleuritic cp and tachycardia?

Pulmonary Embolism (PE)

Explanation:

A pulmonary embolism is a condition where one of the main arteries in the lungs is blocked by a substance that has moved from elsewhere in the body through the bloodstream.

This would be a cause for concern for patients with pleuritic CP because patients with PE's usually present with shortness of breath, chest pain particularly upon breathing in and coughing up blood and due to its position in the lungs, it can also be life-threatening. This symptoms are also very similar and can result in a PE being missed completely on examination causing it to be a high risk

"1. it should be, it has been for about 20 years, and it's really not much different in the end than breeding animals to have particular traits. there are always concerns about genetically engineered animals/plants affecting the environment in unexpected negative ways, but i can't think of an example where the fears didn't turn out to be baseless.  

first, as you point out, it would be a great advance in pharmacology, to be able to tailor drugs and their doses to me. the pros involve better medical treatment. the cons involve privacy issues like insurance companies denying coverage to people with genetic risk factors. looking at dna markers wouldn't affect the frequency of genetic diseases, but it would allow detection of them earlier. and ok, actually i suppose that if people used this information to avoid having children with genetic diseases, some might decrease in frequency."
