Also, the treatment method can improve clinical effectiveness [OR = 2.25, 95% CI (1.97, 2.58), P < 0.001], increase 6-min walking distance (6MWD) [SMD = 1.87, 95% CI (1.33, 2.41), P < 0.0001] and left ventricular ejection fraction (LVEF) [SMD = 1.08, 95% CI (0.83, 1.33), P < 0.0001], and decrease the Minnesota Living with Heart Failure Questionnaire (MLHFQ) scores [SMD = −2.03, 95% CI (−3.0, −1.07), P < 0.0001], BNP levels [SMD = −2.07, 95% CI (−2.81, −1.33), P < 0.0001] and NT-ProBNP levels [SMD = −2.77, 95% CI (−4.90, −0.63), P < 0.05]. Here, NPPB is linked to heart failure.
