10 intramyocardial injections of 0.2 mL each of auto-CD34+ cells at a dose of 1 x 10^5 (=100000) cells/kg bodyweight
Eligible subjects will receive subcutaneous injections of 5 µg/kg/day G-CSF for 5 days to mobilize CD34+ cells from the bone marrow to the peripheral blood. Mononuclear cells (MNCs) will be collected via apheresis on day 5. On the day of the cell/placebo injection (day 6), the apheresis product will be enriched for CD34+ cells using the Isolex 300i Magnetic Cell Selection System (Baxter Healthcare). Autologous CD34+ cells will be delivered in 10 intramyocardial injections of 0.2 mL at a dose of 1 x 10^5 (=100000) cells/kg bodyweight each using the MyoStar injection catheter (Biosense Webster, Inc.) into the target areas of myocardial ischemia.

O que o estudo está medindo?

Medidas de resultados primários

Medida de resultado
Descrição da medida
Prazo
Number of Angina Episodes Per Week at 6 and 12 Months
Prazo: 6 and 12 months
The number of angina episodes were collected via an electronic subject diary for four weeks at Baseline and at 6 and 12 months. The four-week angina episodes (per week mean) were used as the frequency for each visit. A lower number represents fewer angina episodes. A lower number is better.

Descrição da medida
Prazo
Exercise Treadmill Test According to Modified Bruce Protocol: Mean Change From Baseline in Duration of Exercise
Prazo: Change from Baseline to 6 months and change from baseline to 12 months after treatment
A modified Bruce Protocol Exercise Treadmill Test was used to evaluate duration of exercise in all subjects.
Change from Baseline to 6 months and change from baseline to 12 months after treatment
Number of Participants With Change in Canadian Cardiovascular Society Anginal Classification Levels
Prazo: Baseline and 12 months after treatment

The Canadian Cardiovascular Society (CCS) Functional Classification of Angina is as follows:

  • Class I - Angina only during strenuous or prolonged physical activity
  • Class II - Slight limitation, with angina only during vigorous physical activity
  • Class III - Symptoms with everyday living activities, i.e., moderate limitation
  • Class IV - Inability to perform any activity without angina or angina at rest, i.e., severe limitation
Baseline and 12 months after treatment
Changes From Baseline in Seattle Angina Questionnaire (SAQ) Scores at 6 Months
Prazo: Baseline to 6 months after treatment
Angina symptoms were evaluated based on the Seattle Angina Questionnaire (SAQ), which was used to analyze the following: physical limitations, angina stability, angina frequency, treatment satisfaction, and disease perception. The SAQ consisted of 11 questions with 5 or 6 possible responses. Responses were ordinal values (1-7, 10, 11, 97, depending on the type of question; no uniform ranges throughout); responses that corresponded to the lowest level of functioning (worse outcomes) were assigned values of 1, while responses that corresponded to higher functioning levels (better outcome) were assigned a higher ordinal value. If the response to any of these questions was 97 it was recoded as a missing value. Each scale can have a scored value ranging from 0 to 100. A larger number is better.
Baseline to 6 months after treatment
Changes From Baseline to 6 Months in Short Form 36 (SF-36) Parameters
Prazo: Baseline to 6 months after treatment
The Short Form 36 (SF-36) health survey form was used to analyze physical functioning, role limitations due to physical health, bodily pain, general health perceptions, vitality, social functioning, role limitations due to emotional problems, general mental health, and health transition. Responses were coded as ordinal numbers going from worst (=1) to best (=highest number). These ordinal scores were transformed into scales ranging from 0 to 100. Higher numbers are generally considered better.
Baseline to 6 months after treatment
Change in Anti-anginal Medication (ie, Nitroglycerin) Use
Prazo: Baseline to 6 months
The mean nitroglycerin use per week was analyzed at baseline and 6 months
Baseline to 6 months
