Cardiac Rehabilitation for Cardiovascular Risk Reduction in People With Severe and Persistent Mental Illness

Overview

The goal of this prospective, randomized trial is to explore the link between cardiovascular disease and mortality in individuals with severe and persistent mental illness (SPMI). The main question it aims to answer is: Is a primary prevention cardiac rehabilitation intervention feasible and effective at reducing cardiovascular risk in people with a primary psychotic disorder or bipolar disorder?" Participants will undergo a multi-component primary prevention intervention program. Researchers will compare with a control group to see if cardiovascular risk reduction is attained.

This prospective, randomized study aims to recruit 46 adults with schizophrenia, schizoaffective disorder, or bipolar disorder, who are classified as intermediate or high 10-year risk for a cardiovascular event, into a multi-component cardiac rehabilitation intervention program. The aim is to explore the feasibility and efficacy of this multi-component primary prevention intervention program in reducing cardiovascular risk in individuals with SPMI. Evidence supports a high burden of cardiovascular disease and mortality in individuals with SPMI. In link, multiple studies outline disparities in access to quality cardiovascular care in people with SPMI. Given the high CV risk factor burden in people with SPMI and the disparity in access and quality of care, there is a need to screen for CV risk factors and initiate and monitor guideline-directed therapies in people with SPMI. Intervention outcomes will be measured using the Framingham 10-year cardiovascular risk score, the Framingham 30-year cardiovascular risk score, the PRIMOSE BMI and Lipid risk scores, the EQ-5D-5L scale and the CGI score. Continuous variables will be displayed as means, with associated standard deviations. Categorical variables will be represented as frequencies and percentages. Subsequent comparative analysis will take place, where the overall cohort will be characterized into high risk (top quartile) and low risk (bottom quartile) cohorts. This will be accomplished using the chi-squared test or the Fisher exact test, along with the student's t test and the Mann-Whitney U test when appropriate. SPSS 24.0 will be the statistical software used.
