Ideal Cardiovascular Health Metrics on the New Occurrence of Peripheral Artery Disease: A Prospective Cohort Study in Northern China

Peripheral artery disease (PAD) is a common atherosclerotic disease which could lead to severe cardiovascular and cerebrovascular events. Previous studies have indicated the ideal cardiovascular health (ICVH) was associated with many atherosclerotic diseases and cardiovascular events. This study aimed to find out the relationship between ICVH metrics and the new occurrence of PAD. We collected information of baseline from 2010 on the seven ICVH metrics (including smoking, body mass index, dietary intake, physical activity, blood pressure, total cholesterol and fasting blood glucose); and assessed PAD by ankle brachial index among the enrolled participants. The relationship between the ICVH metrics and new occurrence of PAD was analyzed using the multivariate logistic regression in 2018. There were 214 participants were diagnosed with the new occurrence of PAD during the follow-up visit. Participants with PAD tend to be older, with a lower level of education and a higher morbidity of hypertension. Among the seven ICVH metrics, BMI seems to be the most sensitive metric to the occurrence of PAD after adjusting the other risk factors (HR (95% CI) = 0.704 (0.529-0.937), P = 0.0163). We further found out as the number of ICVH metric increased, the morbidity of PAD decreased gradually (HR (95% CI) = 0.888 (0.801-0.984), P for trend= 0.0240). There is no difference between different age and gender groups. The ICVH metrics affect the new occurrence of PAD in a Chinese population. It enhances the importance of ideal health behaviors and factors in the prevention of PAD.
