(CBS) - Swiss researchers say a new test can quickly tell if someone experiencing chest pains is actually having a heart attack. People who go to the emergency room with chest pains undergo several tests - including an electrocardiogram and blood work. Scientists developed a formula that computes the results of those tests to determine if the patient is having a heart attack. A new study found it diagnosed 77 percent of patients - others required further observation. More study is needed before the test is ready for clinical use.
