Doença arterial obstrutiva periférica e índice tornozelo-braço em pacientes submetidos à angiografia coronariana

Abstract

Objective: To evaluate the prevalence of peripheral arterial disease (PAD) in patients with coronary arterial disease, To evaluate the relation between ankle-brachial index (ABI) and coronary arterial disease, and its correlation with cardiovascular risk factors, Method: ABI investigated with Doppler ultrasonic device, Clinical characteristics researched: age, gender, diabetes, hypertension, alcoholism, smoking and obesity, Population: 113 patients who had coronary angiography, First analyses: 2 groups - absence and presence of coronary arterial disease, Second analyses: 3 groups - Group 1 - absence of coronary lesion; Group 2 - stenosis <70%; and Group 3 - stenosis =70%, Third analyses: 2 groups - absence and presence of PAD, Results: 90,76% of patients with coronary arterial disease presented PAD, There were significant difference including age (p<0,001), hypertension (p<0,001), smoking (p<0,001), body mass index (BMI) (p<0,001), systolic blood pressure (SBP) (p<0,001), diastolic blood pressure (DBP) (p<0,001) and pulse pressure (PP) (p<0,001) and ABI (p<0,001) between patients with and without coronary lesion, There were significant difference including age (p<0,001), diabetes (p=0,030), hypertension (p<0,001), smoking (p<0,001), BMI (p<0,001), SBP (p<0,001), DBP (p<0,001) and PP (p<0,001) and ABI (p<0,001) between patients divided as severity of coronary arterial disease, There were significant difference including age (p<0,001), hypertension (p<0,001), smoking (p<0,001), BMI (p<0,001), SBP (p<0,001), DBP (p<0,001) and PP (p<0,001) between patients with and without PAD, By Logistic Regression Analysis, old obese patients with ABI<0,90 have a risk of coronary lesion of 98,93%, Conclusion: ITB<0,90 might be a marker of coronary arterial disease in patients at risk of cardiovascular diseases,.
