Via EurekAlert!: "injections of adult patients' own CD34+ stem cells reduced reports of angina episodes and improved exercise tolerance time in patients with chronic, severe refractory angina (severe chest discomfort that did not respond to other therapeutic options). The phase II prospective, double-blind, randomized, controlled clinical trial was conducted at 26 centers in the United States ... The objective of the trial was to determine whether delivery of autologous (meaning one's own) CD34+ stem cells directly into multiple targeted sites in the heart might reduce the frequency of angina episodes in patients suffering from chronic severe refractory angina, under the hypothesis that CD34+ stem cells may be involved in the creation of new blood vessels and increase tissue perfusion. ... While we need to validate these results in phase III studies before definitive conclusions can be drawn, we believe this is an important milestone in considering whether the body's own stem cells may one day be used to treat chronic cardiovascular conditions. ... At six months after treatment, patients in the low-dose treatment group reported significantly fewer episodes of angina than patients in the control group (6.8 vs. 10.9 episodes per week), and maintained lower episodes at one year after treatment (6.3 vs. 11 episodes per week). Additionally, the low-dose treatment group was able to exercise (on a treadmill) significantly longer at six months after treatment, as compared with those in the control group (139 seconds vs. 69 seconds, on average)." If you want access to this sort of treatment now, and are resident in the US, going abroad as a medical tourist is your only realistic option. Otherwise you may still be waiting five or ten years from now: the FDA moves to approve treatments very slowly, when it moves at all.
