Performance of the "CCS Algorithm" in real world patients.

Background: With the publication of the 2014 Focused Update of the Canadian Cardiovascular Society Guidelines for the Management of Atrial Fibrillation, the Canadian Cardiovascular Society Atrial Fibrillation Guidelines Committee has introduced a new triage and management algorithm; the so-called "CCS Algorithm". The CCS Algorithm is based upon expert opinion of the best available evidence; however, the CCS Algorithm has not yet been validated. Accordingly, the purpose of this study is to evaluate the performance of the CCS Algorithm in a cohort of real world patients.

Identifying patients at low risk for activity-related events: the RARE Score.

Purpose: To prospectively assess whether the Risk of Activity Related Events (RARE) Score accurately identifies patients who are at low risk of experiencing an adverse event while exercise training at cardiac rehabilitation.

Methods: Individuals screened for entry into cardiac rehabilitation were classified as high-risk (RARE Score ≥ 4) or low-risk (RARE Score < 4) using the RARE Score. Patients were followed until program completion or withdrawal, and adverse events were documented.

High and low contact frequency cardiac rehabilitation programmes elicit similar improvements in cardiorespiratory fitness and cardiovascular risk factors.

Aim: Cardiac rehabilitation (CR) is a proven intervention that substantially improves physical health and decreases death and disability following a cardiovascular event. Traditional CR typically involves 36 on-site exercise sessions spanning a 12-week period. To date, the optimal dose of CR has yet to be determined.

Interval and continuous exercise elicit equivalent postexercise hypotension in prehypertensive men, despite differences in regulation.

Equicaloric bouts of interval (IE: 5 × 2:2 min at 85% and 40% maximal oxygen uptake) and steady state (SS: 21 min at 60% maximal oxygen uptake) exercise were performed by 13 older prehypertensive males on separate days, at equivalent times of day, to assess the influence of exercise mode on postexercise hypotension (PEH). Exercise conditions were compared with a control session. Cardiovascular measures were collected for 30 min prior to, and 60 min following exercise.
