Randomized Controlled Trial Comparative Study Clinical Trial
Transmyocardial laser revascularisation compared with continued medical therapy for treatment of refractory angina pectoris: a prospective randomised trial. ATLANTIC Investigators. Angina Treatments-Lasers and Normal Therapies in Comparison.
Transmyocardial revascularisation (TMR) is an operative treatment for refractory angina pectoris when bypass surgery or percutaneous transluminal angioplasty is not indicated. We did a prospective randomised trial to compare TMR with continued medication. ⋯ TMR lowered angina scores, increased exercise tolerance time, and improved patients' perceptions of quality of life. This operative treatment provided clinical benefits in patients with no other therapeutic options.

No study to date, however, has examined the extent to which a dying patient's will to live fluctuates as death approaches. ⋯ Among dying patients, will to live shows substantial fluctuation, with the explanation for these changes shifting as death approaches.
