Zen-meditation practitioners showed greater increases in blood-pressure-waveform parameters reflecting heart ejection ability, aorta compliance, arterial elasticity, and aortic valve function, along with a greater decrease in a parameter indicating peripheral resistance, compared to a control group. All changes were statistically significant. The authors infer that Zen meditation may effectively improve characteristics of the cardiovascular system.
