A recent study published in the International Journal of Cardiology evaluated whether comprehensive cardiac rehabilitation (CR) in patients with cardiovascular disease (CVD) could improve various hemodynamic parameters, obtained using simple non-invasive tests. This prospective study analyzed 48 CVD patients: 38 with a CR program and 10 without a CR program; and followed them for 12 months. Various parameters were measured at baseline and after 12 months, as well as blood pressure (BP), severity of atherosclerosis [arterial velocity pulse index (AVI), and atrial pressure volume index] were determined. It was observed that the main hemodynamic parameters did not change between baseline and 12 months in both groups. Patients in the CR group were divided into higher (H-) and lower (L-) systolic BP (SBP) or AVI according to the average value of SBP or AVI at baseline in the CR group. Patients with H-SBP or H-AVI in the CR group exhibited a significant decline in SBP or AVI at 12 months. In addition, patients in the CR group were divided into H- and L-cardiac index (CI) or CVRR according to the average value of CI or coefficient of variation of the R-R interval (CVRR) at baseline in the CR group. The results showed that patients with L-CI or L-CVRR in the CR group significantly improved after 12 months. Hence, it was concluded that CR may lead various hemodynamic parameters obtained using simple non-invasive tests to their appropriate levels.
