Peripheral arterial disease (PAD) increases with age and ankle-brachial index (ABI) ≤ 0.9 is a noninvasive marker of PAD. The purpose of this study was to identify risk factors related to a low ABI in the elderly using two different methods of ABI calculation (traditional and modified definition using lower instead of higher ankle pressure). A cross-sectional study was carried out with 65 hypertensive patients aged 65 years or older. PAD was present in 18% of individuals by current ABI definition and in 32% by modified method. Diabetes, cardiovascular diseases, metabolic syndrome, higher levels of systolic blood pressure and pulse pressure, elevated risk by Framingham Risk Score (FRS), and a higher number of total and antihypertensive drugs in use were associated with low ABI by both definitions. Smoking and LDL-cholesterol were associated with low ABI only by the modified definition. Low ABI by the modified definition detected 9 new cases of PAD but cardiovascular risk had not been considered high in 3 patients when calculated by FRS. In conclusion, given that a simple modification of ABI calculation would be able to identify more patients at high risk, it should be considered for cardiovascular risk prediction in all elderly hypertensive outpatients.

Elevated risk of fatal and non-fatal cardiovascular events is associated with high prevalence of peripheral arterial disease, with assessment through the ankle-brachial index (ABI). This study aimed to demonstrate that the ABI and the Edinburgh Claudication Questionnaire are tools to be used by nurses in prevention and/or treatment of CVD (cardiovascular disease). A cross-sectional study was carried out with patients from a cardiovascular clinic. The Edinburgh Claudication Questionnaire was applied and the ABI was measured with the formula (ABI= Blood Pressure Ankle/Blood Pressure Brachial). A total of 115 patients were included, most were females (57.4%), aged 60.6 ± 12.5 years. The most prevalent risk factors were hypertension (64.3%), physical inactivity (48.7%) and family history (58.3%). The study showed that abnormal ABI was frequently found and 42.6% of the patients with abnormal ABI showed intermittent claudication. The method to evaluate the ABI associated to the Edinburg Claudication Questionnaire, can be easily used by nurses in the clinical evaluation of asymptomatic and symptomatic CVD patients.

Background: This cross sectional study investigated the clinical use of the ankle-brachial index (ABI) and toe brachial index (TBI) in 91 type 2 diabetic foot ulcer patients who visited the diabetic foot clinic, Prince Sultan Military Medical City, Saudi Arabia during July 2017 and January 2018. Materials and Methods: The ABI and TBI facilitated the detection of peripheral arterial disease (PAD) and the patients’ medical records were used to collect the clinical and demographic variables. The variables of duration (p = 0.047) and treatment (p = 0.046) of the ABI showed significant differences. Age (p = 0.034) and duration (p = 0.001) were the factors related to the diagnosis of TBI by the “χ2” test. Results: From the TBI, 26.4% of the patients were found to have PAD, while the ABI showed that 21.8% of patients had the condition. However, no statistical significance was noted. From the regression analysis, the variable duration of diabetes (≥ 20 years of age) was recognized as an independent risk factor for TBI. Conclusion: In conclusion, it is recommended both the ABI and TBI to be used as screening tests for PAD in diabetic foot ulcer patients.

China is at a stage of rapid urbanization over the past decades, and the association of urbanization with cardiovascular disease has been confirmed by previous studies. However, few studies assessed the association of urbanization with cardiovascular risk factors, especially in Chinese population. We conducted a cross-sectional, populational-based study, using data from China Health and Nutrition Survey (CHNS) in 2009. The logistic regression was used to assess the association of urbanization measured by urban index with cardiovascular risk factors (diabetes mellitus, hypertension, dyslipidemia, obesity, smoking, physical activity and fruits and vegetables consumption), varied with sex. The current study included 18,887 participants enrolled (mean age 39.8 ± 19.8 years; 52.2% female) who live in China. In regression model, the urban index was significantly associated with the variations of cardiovascular risk factors for male, including diabetes (OR 1.34, 95% CI: 1.22–1.48), hypercholesterolemia (OR 1.15, 95% CI: 1.09–1.22), never smoking (OR 0.92, 95% CI: 0.89–0.96), higher fruits and vegetables consumptions (OR 0.93, 95% CI: 0.87–0.99), higher body mass index (BMI) (OR 1.16, 95% CI: 1.10–1.22), and higher physical activity (OR 0.69, 95% CI: 0.66–0.73). Compared with the male, the associations of urban index with cardiovascular risk factors for female were similar, but not for BMI (OR 1.00, 95% CI: 0.96–1.05). The present finding emphasizes the changes of cardiovascular risk factors associated with urbanization in China, and indicated that close attention should be paid to the risk of hypercholesterolemia, diabetes and men’s obesity in the process of urbanization.

Cardiovascular risk factors in people on antiretroviral treatment (ART) are poorly documented in resource-constrained settings. A cross-sectional study was conducted in 2009 to assess prevalence of diabetes and hypertension in a sample of 242 HIV-infected patients who had initiated ART between 1998 and 2002 in Dakar, Senegal (ANRS 1215 observational cohort). World Health Organization (WHO) criteria were applied to diagnose diabetes and hypertension. Multiple logistic regressions were used to identify factors associated with diabetes and hypertension. Patients had a median age of 46 years and had received ART for a median duration of about 9 years. 14.5% had diabetes and 28.1% had hypertension. Long duration of ART (≥119 months), older age, higher body mass index (BMI), and higher levels of total cholesterol were associated with higher risks of diabetes. Older age, higher BMI at ART initiation, and higher levels of triglycerides were associated with higher risk of hypertension. This study shows that diabetes and hypertension were frequent in these Senegalese HIV patients on ART. It confirms the association between duration of ART and diabetes and highlights the need to implement programs for prevention of cardiovascular risk factors in HIV patients from resource-constrained settings.

Background: Hypertension is a major modifiable risk factor for cardiovascular diseases and research studies done in Nigeria observed prevalence rate of hypertension to range from 26.4% to 36.9%. Aim: This study aimed to evaluate the sociodemographic, clinical, behavioral and cardiovascular risk factors associated with hypertension in Awka, South East, Nigeria. Methods: Cross-sectional study was used.391 participants aged from 18 years above were recruited for this study. Structured questionnaires were constructed in line with World Health Organization Step approach was utilized for data collection. Hypertension was defined as systolic blood pressure ≥ 140 mmHg and Diastolic blood pressure ≥ 90 mmHg. Chi-square and independent sample T test were used to test comparison between two groups. Results: The mean age of the subjects was 45.87±17. 49.33.7% of retired subjects has the highest prevalence was statistically associated with hypertension in occupational status of the subjects, marital status was statically significant with hypertension and prevalence of hypertension among the subjects were 81.1%, 8.5%, 8.6% for married, single and divorcee respectively, (P<0.001) and also no association was observed between hypertension and subjects that occasionally use high salt often(x2=0.341, P>0.001). Conclusion: The study showed that age, family history of hypertension, consistent increase in blood pressure, occupational and marital status are associated risk factors of hypertension in Awka, South East, Nigeria. There is need to create awareness on the risk factors and encourage changes in sedentary life style.
