COVID-19 studies are our top priority.

For new and updated trial submissions, we are processing trials as quickly as possible and appreciate your patience. We recommend submitting your trial for registration at the same time as ethics submission.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Description of intervention(s) / exposure
A single-centred, prospective cross-sectional analytical study will be carried out. Patients with diagnosed Cardiovascular disease conditions will be recruited from outpatient clinics of acute care hospital. Written informed consent will be taken from all patients who are willing to participate the study at screening stage. At the time of enrolment to the study, the participants will be given a unique study identification number, which will be used to identify the participants throughout the study, until study completion. No identifiable information will be used in the records. Study master list with identifiers will be securely kept separately from the list of unique IDs given to the participants and study data records. The participants will be screened for their frailty states (30 min clinical assessment involving muscle strength assessment by hand grip strength measurement, physical and cognitive function assessments, dietary intake of vitamin D and sun exposure levels assessments by questionnaires) and blood tests to assess vascular function and inflammatory markers and plasma vitamin D levels.

Study design
Random sample
Statistical methods / analysis
Descriptive analysis will be carried-out to assess the demographic and situational data.
Study participants will be stratified to sarcopenic and non-sarcopenic based on accepted cut-off points.
Data from sarcopenic and non-sarcopenic sub groups will be evaluated by t-tests (un-paired)/Mann–Whitney U test, linear regression analysis and multivariate logistic regression to evaluate the independent effects.
Study 1: Data will be stratified based on vitamin D status and frailty/sarcopenic status.
