Angina, Stable, Chest Pain, Heart Failure, Microvascular Angina
Conditions
Brief summary
This RCT aims to determine if it is possible to perform acupuncture on men and women diagnosed with stable angina who have symptoms, chest pain, and/or chest discomfort. The investigators want to determine if acupuncture reduces the pain and other symptoms of angina, chest pain, and chest discomfort. The investigators also want to examine whether this study is acceptable to the participants, and by carrying out this study the investigators will be able to tell how many participants they will need in a future larger study to further test acupuncture to reduce the symptoms of angina in women.
Detailed description
The investigators are conducting a RCT aimed at gathering feasibility, and initial efficacy for a randomized controlled trial (RCT) to test the effect of acupuncture on anginal symptoms, chest pain, and chest discomfort in men and women. The investigators long term goal is pain and symptom management resulting in improved functional status and quality of life for men and women with stable angina, chest pain, and chest discomfort. This study will include 69 community dwelling men and women with a medically confirmed diagnosis of stable angina, chest pain which includes non-ischemic or ischemic cardiomyopathy, microvascular coronary dysfunction (MCD), heart failure with preserved ejection fraction (HFpEF), heart failure with reduced ejection fraction (HFrEF), or chest discomfort whose pain and associated symptoms have not been completely controlled with guideline-directed medical management. The investigators will use a randomized attention control design with 13 men and women assigned to initial acupuncture and 13 to control. Participants in the experimental group will receive a standardized acupuncture point prescription two treatments per week, for 5 weeks. The attention control group will receive non-pain related video health education over 5 weeks equal to the approximate 10 hours of treatment for the acupuncture group.
Interventions
Standardized acupuncture treatment administered for 30 minutes each session
Attention control group will watch health education videos the equivalent of 10 hours from randomization up to study completion.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Feasibility of Study Protocol | After 10th acupuncture treatment, at 5 weeks post-baseline (study completion) | Feasibility was measured by recruitment (%), retention (%), completion (%). Feasibility was defined as ≥ 80% recruitment, ≥75% retention following enrollment, and ≥ 80% completion. |
| Protocol Acceptability Scale for Treating Angina With Acupuncture | After 10th acupuncture treatment, at 5 weeks post-baseline (study completion) | Protocol Acceptability Scale for Treating Angina with Acupuncture is a 9-item instrument used to measure acceptability of the study processes and protocols. Items are measured on a 0 to 2 scale, where 0 means did not like the study and did not like acupuncture, and 2 means liked the study and liked acupuncture. The protocol was deemed to have high acceptability if 80% of participants scored ≥ 80% of possible points on the acceptability scale. The investigators calculated the mean score for each of the 9 questions in each arm, divided the total score for the 9 questions by the maximum possible points for the measure (18 x number of participants in each arm), and converted the total mean scores to percentage of participants who liked the study/liked acupuncture in each arm. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Average Pain Intensity From the McGill Pain Questionnaire | From before first treatment at baseline to after 10th acupuncture treatment (study completion) at 5 weeks | Average Pain Intensity from the McGill Pain Questionnaire is the average of pain now, least pain in the past 24 hours, and worst pain in the past 24 hours. Average Pain Intensity is scored on a 0 to 10 Likert type scale with 0 = no pain and 10 = excruciating pain. Pain intensity is the pre-specified outcome measure, while pain now and least and worst pain are values used to calculate average pain intensity and were not specified outcome measures. |
| Seattle Angina Questionnaire-7 (SAQ-7) | From before first treatment at baseline to after 10th acupuncture treatment (study completion) at 5 weeks | The instrument consists of 7 items measuring functional status, symptoms, and quality of life on participants. Item responses are coded sequentially from worst to best status and range from 1 to 6, except Quality of Life (range 1-5). Scores are generated for each domain and are scaled 0 to 100, with 0 denoting the worst and 100 the best possible status. |
