METHODS: A nonrandomized prospective trial was performed at a university hospital. A total of 516 of 972 consecutive patients referred for coronary angiography because of known or suspected angina pectoris were asked to participate in the study. Of these, 275 gave informed consent to a standardized manual examination of their spine and thorax. Diagnoses of an experienced chiropractor on cervicothoracic angina patients. Myocardial perfusion imaging and coronary angiography were used for validation. A set of candidate variables from patient history and clinical examination were tested for their role in the decision-making process.
RESULTS: Eighteen percent of the patients were diagnosed with cervicothoracic angina. Of these, 80% had normal myocardial perfusion compared to 50% of cervicothoracic angina-negative patients. The main determinants of the decision-making process could be identified.
CONCLUSION: An experienced chiropractor could identify a subset of patients with angina pectoris as having cervicothoracic angina. Systematic manual palpation of the spine and thorax could be used as part of the clinical examination together with basic cardiological variables to screen patients with chest pain allowing for improvements in referral patterns for specialist opinion or angiography.
