The 2012 American Association of Cardiovascular and Pulmonary Rehabilitation (AACVPR) Stratification Algorithm for Risk of Cardiovascular Event45 was perceived by panel members to be useful when screening patients with lymphangioleiomyomatosis with a known history of cardiovascular disease. During preparticipation screening for LAMFit, providers can use this stratification algorithm to classify a patient as high, low, or moderate risk for cardiovascular event during exercise, and choose whether to refer them to participate in LAMFit (no, low, or moderate risk) or to a center-based rehabilitation program instead (high risk). Providers can refer to the AACVPR Registry Resources website46 for more information about the algorithm. CABG = coronary artery bypass graft; CHF = congestive heart failure; MET = metabolic equivalent; MI = myocardial infarction; PVC = premature ventricular contraction.
