Manual therapy for patients with stable angina pectoris: a nonrandomized open prospective trial

To examine if participants with chest pain originating from the spine would benefit from manual therapy.

A nonrandomized, open, prospective trial was performed at a tertiary hospital. Patients who were referred for coronary angiography because of known or suspected stable angina pectoris were invited to participate in this study. A total of 275 took part, 50 were diagnosed as cervicothoracic angina (CTA)-positive (chest pain from the cervicothoracic spine) and 225 as CTA-negative. The intervention performed was manual therapy according to chiropractic standards. Patient self reported questionnaires at baseline and 4-week follow-up, including pain measured with an 11-point box scale, Short Form 36 (quality of life), and perceived improvement.

Approximately 75% of CTA-positive patients reported improvement of pain and of general health after treatment, compared with 22% to 25% of CTA-negative patients (P < .0001). Pain intensity decreased in both groups with consistently larger decreases for all measures of pain among CTA-positive patients. Short Form 36 scores increased in the CTA-positive group in 5 of 8 scales and remained unchanged in the CTA-negative group.

This study suggested that patients with known or suspected angina pectoris and a diagnosis of CTA may benefit from chiropractic manual therapy. Methodologically, sound randomized clinical trials are needed to corroborate our results.
