Introduction: Smoking and diabetes are known to be associated with increased arterial disfunction. Blood pressure, heart rate, and pulse pressure are simple indicators of cardiovascular functioning. Pericardium 6 (PC6) is an acupoint that has been shown to modify cardiovascular pathophysiology.Aim: This study aimed to compare the effects of manual acupuncture at PC6 on cardiovascular parameters in healthy subjects versus smokers and type 2 diabetic patients.Methods: Three study groups: 14 healthy subjects, 19 smokers, and 15 patients with type 2 diabetes mellitus were compared. Systolic and diastolic blood pressures and heart rate were measured through an oscillometric device. Pulse pressure was calculated as the difference between systolic pressure with diastolic pressure. PC6 right was stimulated by manual needling for 5 min (1-6 min). Parameters were compared in each subject in the pre- versus post-acupuncture periods (0 versus 20 min, respectively).Results: Acupuncture in healthy people decreased SP, and HR both significantly; in smokers, decreased SP, DP, and HR all significantly and in diabetic patients, decreased SP, DP, and HR all significantly. The effect of acupuncture on systolic pressure increases with age in healthy subjects and diabetics patients. Otherwise, it decreases with age in smokers. The effect of acupuncture on heart rate increases with age in healthy subjects. Otherwise, it decreases with age in diabetics’ type 2 patients and has no relationship in smokers.Conclusion: Manual acupuncture of PC6 evoked a diminution of systolic pressure, diastolic pressure, and heart rate in healthy subjects, smokers, and diabetic patients. Besides, acupuncture significantly decreased pulse pressure in smokers; and not significantly in healthy subjects or diabetics patients. A decreased in HR response age-related to acupuncture was observed in older diabetics. These results suggest that diabetic patients present a refractory state to acupuncture stimulation, probably due to vascular neuropathy.
