Table 5 displays the LDL-C level attainment for those patients who completed CR in 2019, stratified by guidelines used. The number of patients for whom LDL-C data prior to commencement to commencing CR is given, with percentage of row total in brackets. The mean measured LDL-C level prior and following completion of cardiac rehab is given with 95% confidence intervals for the mean in brackets. The number of patients who met their absolute LDL-C category for their specified risk category is displayed with row percentage displayed in brackets. The percentage in reduction of LDL-C from measured or calculated baseline LDL-C is given, with 95% confidence intervals for the mean displayed in brackets. The number of patients who achieved an over 50% reduction in their LDL-C level when compared to their measured or calculated baseline LDL-C level is given with row percentage in brackets. The number of patients who met their LDL-C guidelines as defined by their contemporary guidelines is displayed with row percentage in brackets. For the 2016 cohort, this required achievement of a reduction of LDL-C below an absolute target, and for those at very high and high risks, a relative reduction of at least 50% LDL-C when compared to measured or calculated baseline lipids. For the 2019 cohort, both of these criteria must be satisfied
CR cardiac rehabilitation
aBaseline lipids do not refer to ‘LDL-C pre-rehab’ column, but instead the measured LDL-C level for those not on LLT (or the calculated LDL-C level of a patient, adjusted for LLT effect), prior to commencing CR
