Overview
Brief Summary
The goal of this clinical trial is to compare, at 3 months, the effects of a yoga intervention on physical health, including balance, muscle strength, physical activity levels, cardiac autonomic function, and physical vulnerability, as well as psychological health, including depressive symptoms and anxiety, in cardiac patients who are older than 65 years old and randomized to the intervention or control group. The main questions aim to 1) determine if yoga can improve physical health outcomes such as balance, muscle strength, cardiac function, and physical vulnerability in older adults with cardiovascular disease, and 2) determine if yoga can positively impact psychological health, including reducing depressive symptoms and anxiety in this population. Participants in the intervention group will attend yoga sessions twice a week for three months. The intervention group will be asked to complete surveys and physical function assessments at the beginning and three months later. Researchers will compare the intervention group and the control group to see if there is any difference and improvement in physical and psychological health between the two groups.

Outcomes
Primary Outcomes
Retention rate
Time Frame: Three months
The retention rate will be calculated by dividing the total number of patients by the number of patients who will complete the study and then multiplying it by 100.
Intervention acceptability
Time Frame: Three months
The investigators will use modified versions of the Treatment Acceptability Adherence Scale (TAAS) to assess acceptability of the yoga intervention at 3-months follow-up. The TAAS is a 10-item self-report questionnaire designed to evaluate treatment acceptability and adherence. Items are rated on a 7-point Likert-type scale (1 = disagree strongly; 7 = agree strongly). The total score is a sum of seven items, ranging from 10 to 49 where a higher score means greater adherence.
Recruitment rate
Time Frame: Three months
The recruitment rate (%) will be calculated by dividing the total number of patients enrolled by approached eligible patients and then multiplying it by 100.
Intervention adherence rate
Time Frame: Three months
The intervention adherence rate will be calculated by dividing the total number of sessions attended by the total number of intervention sessions (i.e., 24) and multiplying that number by 100.
Intervention satisfaction
Time Frame: Three months
The investigators will use modified versions of the Client Satisfaction Questionnaire (CSQ) to assess the satisfaction of the yoga intervention at 3-month follow-up. The CSQ is an 8-item self-report questionnaire to evaluate participant satisfaction with a specific intervention. Items are rated on a 4-point Likert-type scale (1 = very satisfied; 4= quite dissatisfied). The total score is the sum of eight items, ranging from 8 to 32, where a higher score indicates greater satisfaction with the intervention. This instrument was validated for patients and has internal consistency reliability.
