Brief Summary:

It is hypothesized that the addition of formal cardiac rehabilitation to standard care will result in long-term improvements in cardiovascular fitness and functional capacity in individuals who have suffered a transient ischemic attack (TIA) or minor stroke.

Furthermore, it is proposed that the addition of cardiac rehabilitation will influence stroke risk, physical activity participation, strength, and quality of life.

Condition or disease	Intervention/treatment
Transient Ischemic Attack	Behavioral: Cardiac Rehabilitation

Detailed Description:

A transient ischemic attack (TIA) is defined as an episode of neurological dysfunction caused by focal brain ischemia lasting less than 24 hours. Once an individual has suffered a TIA, preventative measures can be taken to target modifiable risk factors, one of which is physical inactivity. The current proposal focuses on the use of an established model of care (cardiac rehabilitation (CR)) and applies it to those who have suffered a TIA in order to maximize physical activity and minimize risk of future cardiovascular events. This will be a one-group pre/post design study. Participants will undergo measures at baseline, 6 and 12 months (cardiovascular fitness, 6 minute walk test, quality of life, diet, strength, physical activity, and Framingham Profile stroke risk (plasma lipids, blood pressure, medication use)).

Group/Cohort	Intervention/treatment
Exercise; Participants in this group will participate in Cardiac Rehabilitation, carrying out an exercise program which will last 6 months and combine both resistance and aerobic training.	Behavioral: Cardiac Rehabilitation; Individualized cardiac rehabilitation for 6 months, including health education sessions, as well as supervised exercise classes which include aerobic and resistance training.

Outcome Measures

Primary Outcome Measures :

1. Primary outcomes include improvements in cardiovascular fitness, functional capacity, and physical activity levels in individuals with TIA. This will be measured using a cardiopulmonary exercise test and a 6 minute walk test. [ Time Frame: Baseline, 6 months, 12 months ]

Secondary Outcome Measures :

1. Secondary outcome measures are plasma lipid analysis, questionnaires pertaining to quality of life, physical activity and diet diaries, and results from the Montreal Cognitive Assessment and MRI analysis. [ Time Frame: Baseline, 6 months, 12 months ]

Study Population

TIA

Criteria

Inclusion Criteria:

• Diagnosed with TIA
• Three months post-TIA
• Ability to understand the process and instructions for exercise training and provide informed consent

Exclusion Criteria:

• Resting Blood Pressure greater than 160/100 despite medication
• Other cardiovascular morbidity which would limit exercise tolerance (heart failure, abnormal BP responses or STsegment depression > 2 mm, symptomatic aortic stenosis, complex arrhythmias)
• Current and extensive exercise participation
• Hypertrophic Cardiomyopathy
• Unstable Angina
• Orthostatic BP decrease of > 20 mm Hg with symptoms
• Other musculoskeletal impairments which would limit the participant's ability to walk sufficient durations
• Pain or other co-morbidities (e.g., unclipped aneurysms, uncontrolled seizures etc.) which would preclude participation
• Cognitive or behavioural issues that would limit participation in exercise testing and training
