Abstract
Peripheral artery disease (PAD), a condition where there is reduced blood flow due to narrowing or blockage of the arteries of the peripheral vasculature, is an epidemic that currently affects eight million people in the United States alone and is a major risk equivalent to having active coronary artery disease (CAD). However, it is commonly underdiagnosed in the general population. Hypertension is a common cardiovascular condition characterized by elevated blood pressure levels. There are several mitigating risk factors that can reduce the risk of complications of PAD, with hypertension playing a major role. This literature review aims to explore the relationship between hypertension and PAD, including their shared risk factors, pathophysiological mechanisms, and management strategies. In addition, we will analyze how this impacts major cardiovascular outcomes, such as critical limb ischemia, vascular amputation, myocardial infarction (MI), ischemic stroke, and cardiovascular-related death by examining relevant studies, current guidelines, and evidence. This literature review is intended to guide practitioners on ideal blood pressure parameters and evidence-based anti-hypertensives that provide overall cardiovascular benefit in both the primary care and hospital-based setting. By understanding the association between hypertension and PAD and the underlying pathophysiological mechanisms, healthcare professionals can improve diagnosis, treatment, and management strategies for affected individuals.

Abstract
Diabetic foot ulcer syndrome is a common complication of diabetes mellitus. Three main factors contribute to it: neuropathy, vasculopathy, and infection. This study was conducted to evaluate the prevalence of peripheral arterial disease (PAD) in diabetic foot ulcer patients and its impact on limb salvage as an outcome. This prospective cross-sectional study included 392 cases, who were divided according to the presence of PAD into 2 groups; patients with PAD were labeled as PAD +ve (172 cases) and those without PAD were labeled as PAD -ve (22 cases). All cases were clinically assessed, and routine laboratory examinations were ordered. Moreover, duplex ultrasound was done for suspected cases of having PAD by examination. Computed tomography angiography was ordered for patients who are in need of a revascularization procedure. Cases were managed by debridement and/or revascularization. After that, these cases were assessed clinically and radiologically for vascularity and infection and the possibility for amputation was evaluated. Infection was classified using Wagner Classification System, and revascularization was decided according to the TASC II system. The incidence of PAD in cases with diabetic foot ulcer syndrome was 43.87%. No difference was detected between the 2 groups regarding age and gender (P > .05). The prevalence of smoking, hemodialysis, ischemic heart disease (IHD), and hypertension was more significantly higher in cases with PAD (P < .05). Revascularization procedures were only performed in cases that had documented severe PAD or chronic limb-threatening ischemia in addition to foot ulcer and/or infection. With regard to limb salvage, it was more significantly performed in cases without PAD (82.3% vs 48.3% in PAD cases; P < .001). Male gender, smoking, ankle-brachial pressure index, hemodialysis, IHD, neuropathy, HbA1C, PAD, and high Wagner classification were predictors of limb amputation (P < .05). PAD is associated with worse outcomes in diabetic foot ulcer patients. Not only does it constitute a great number among diabetic foot ulcer patients, but it also has a negative impact on limb salvage.

Ann Vasc Surg 2022; 85:183-189. [PMID: 35271965 DOI: 10.1016/j.avsg.2022.02.008] [Citation(s) in RCA: 7] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/01/2021] [Revised: 01/06/2022] [Accepted: 02/03/2022] [Indexed: 11/26/2022]
Abstract
OBJECTIVES To analyze the outcomes of Supera stent deployment in Chinese patients with atherosclerotic femoropopliteal artery (FPA) disease in a real-world setting. METHODS This retrospective cohort study collected and analyzed the medical records of 246 consecutive patients who received Supera stents for FPA disease at the China Academy of Chinese Medical Sciences Xiyuan Hospital between February 2017 and December 2019. All study patients underwent balloon angioplasty and were treated with Supera stents (Abbott Vascular, Santa Clara, CA, USA). The primary outcome was the rate of primary patency 12 months after discharge. RESULTS The analyses included 246 consecutive patients and 260 lesions. The mean ± SD age was 73.2±9.9 years and most patients (60.2%) were male. Of the 260 treated lesions, Supera stents were deployed in eight (3.1%) cases after previous stent fracture. Critical limb ischemia was diagnosed in 87.3% of the limbs, and 84 (32.3%) and 83 (31.5%) cases were classified as TransAtlantic Inter-Society Consensus (TASC) C and D, respectively. The majority of the lesions was in situ (80.8%) and located in the superficial femoral artery (45.0%) or the femoropopliteal artery (45.8%). The mean lesion length was 147.7 mm. Nominal deployment (-10% to 10% compression) was the most common deployment scenario (84.1%). The 1-year primary patency rate was 80.6%. Lesions that occurred as restenosis (OR = 3.34, 95% CI: 1.03-10.85, P = 0.045) or in-stent restenosis (OR = 2.88, 95% CI: 1.03-8.07, P = 0.045) were independently associated with occlusion or stenosis after stent deployment. No stent fracture was observed in the study. CONCLUSIONS Our study indicates that the use of Supera stents is feasible for treatment of Chinese patients with FPA disease. The long-term results reveal high primary patency.

BMC Cardiovasc Disord 2022; 22:16. [PMID: 35081909 PMCID: PMC8793153 DOI: 10.1186/s12872-022-02463-6] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/24/2021] [Accepted: 01/17/2022] [Indexed: 01/20/2023] Open
Abstract
Background This study aimed to assess the relationship of a new anthropometric index with left ventricular hypertrophy (LVH) in hypertensive patients among the Han Chinese. Methods The study is a community-based cross-sectional study that included 4639 patients with hypertension and integrated clinical and echocardiographic data. Left ventricular (LV) mass was measured by transthoracic echocardiography. LVH was diagnosed by using the criteria of left ventricular mass indexed (LVMI) over 49.2 g/m2.7 for men and 46.7 g/m2.7 for women. Quartiles of a body shape index (ABSI), body roundness index (BRI), waist circumference (WC), and body mass index (BMI) were used regarding LVH prevalence. The logistic regression model was used to determine the odds ratio (OR) and 95% confidence intervals (CI) of the new anthropometric index and LVH. Receiver operating characteristic (ROC) curve analysis was used to evaluate the predictive ability of the obesity indices for LVH risk.
Results The prevalence of LVH increased across quartiles for ABSI, BRI, BMI, and WC. Comparing the lowest with the highest quartile, adjusted OR (95% CI) for LVH were significantly different for BRI 3.86 (3.12–4.77), BMI 3.54 (2.90–4.31), and WC 2.29 (1.88–2.78). No association was observed for ABSI. According to ROC analysis, the area under the curve (AUC) of BRI was (AUC: 0.653, 95% CI 0.637–0.669), BMI (AUC: 0.628, 95% CI 0.612–0.644), WC (AUC: 0.576, 95% CI 0.559–0.593), ABSI (AUC: 0.499, 95% CI 0.482–0.516). Conclusions This study shows that LVH prevalence increased per quartile across the Han Chinese population with hypertension for ABSI, BRI, BMI, and WC. There is a significant association between BRI and LVH in hypertensive people, while ABSI was not. BRI showed potential for use as an alternative obesity measure in the assessment of LVH.

Abstract
OBJECTIVE Peripheral artery disease (PAD) affects more than 200 million people worldwide, among whom more than two-thirds reside in low- and middle-income countries. China, as the largest low- and middle-income country, faces a challenge from the burden of PAD as the country undergoes economic expansion. We compared the patterns of PAD between China and Western countries to determine if there are differences in risk factors, awareness, or treatment of PAD. METHODS Literature searches were performed both in English databases and Chinese databases covering January 1, 1995, to March 1, 2020. Both landmark and high-quality articles were evaluated. RESULTS The prevalence of PAD in high-income countries increases linearly with age, whereas PAD increases slowly until the middle 60s and exponentially thereafter in China. In contrast with Western countries, the prevalence of PAD in China is reported to be higher in women than in men. There is a higher prevalence of risk factors in China, but the rates of awareness and treatment of these risk factors are low. CONCLUSIONS The lack of awareness and lower rates of treatment and control of PAD and its risk factors in China may be underlying the higher prevalence of PAD in women than in men as well as the steep increase in PAD after the middle 60s. In all countries, more attention should be paid to the planning and implementation of preventative strategies and clinical services. The societal and economic effects of PAD are considerable and ongoing studies are needed to help curtail the burden of this disease.

Abstract
BACKGROUND AND AIMS A previous meta-analysis suggested that the relationship between hyperuricemia and hypertension may be stronger in younger individuals and women. We aimed to investigate the age and sex dependent association of uric acid (UA) and incident hypertension. METHODS AND RESULTS We analyzed data from the Health Examinees Study, a community-based prospective cohort study conducted in Korea from 2004 to 2013. It included 29,088 non-hypertensive subjects aged 40-79 (age, 52.5 ± 7.8 years; men, 31.4%) who had serum UA measurement and participated in the follow-up survey. The risk factors of hypertension were assessed using Cox regression. Over a mean 3.8 years of follow-up, 1388 men (15.2%) and 1942 women (9.7%) were newly diagnosed with hypertension. Upon age- and sex-based stratification, the risk of hypertension was highest in hyperuricemic subjects aged 40-49 years (HR: women, 2.16; men, 1.30). Across the entire cohort, the risk of incident hypertension was higher in groups with higher serum UA levels, and highest in women aged 40-49 years (HR, 1.44; P < 0.001). On multivariable linear regression analysis, the higher the baseline serum UA level, the greater the increase in blood pressure during follow-up, and this effect was strongest in women aged 40-49 years (β = 0.87 and P < 0.01 for systolic blood pressure). CONCLUSIONS The relationship between uric acid and incident hypertension tended to be dependent on age and sex. Younger women are at highest risk of UA-related incident hypertension.

Abstract
PURPOSE OF REVIEW This review of the literature aims to discuss the evidence linking different lipid and apolipoprotein measures to peripheral artery disease. RECENT FINDINGS Measures of atherogenic dyslipidemia, including elevations in total cholesterol and total cholesterol/high-density lipoprotein cholesterol as well as low levels of high-density lipoprotein cholesterol, are strongly associated with future risk of peripheral artery disease. Compared to coronary artery disease, there are fewer data showing an association between low-density lipoprotein cholesterol and future risk of peripheral artery disease. Novel lipid measures, including nuclear magnetic resonance-derived lipoproteins and oxidized lipids, may lead to better assessments of future peripheral artery disease risk. These data highlight the important differences between lipid risk factors for peripheral and coronary artery disease. Improved understanding of these distinctions may lead to new therapeutic options for patients with peripheral artery disease.

Abstract
With a rapidly aging population, the prevalence of hypertension in adults continues to rise, placing a substantial and escalating social and economic burden. Ilex hainanensis Merr. is commonly used as a folk remedy for treating hypertension, dyslipidemia, and inflammation in China. This systematic review aims to evaluate current evidence for the therapeutic effect of Ilex hainanensis Merr. extract (EIH) on essential hypertension. Six electronic databases (Pubmed, MEDLINE, The Cochrane Central Register of Controlled Trials, Chinese Scientific Journals Database, Wanfang and CNKI) were searched to identify eligible randomized controlled trials (RCTs) relevant to EIH on essential hypertension up to Jan 2018. Six RCTs including 772 participants met eligibility criteria. Methodological quality of the trials was generally low. Meta-analysis showed that EIH demonstrated a beneficial effect for lowering systolic and diastolic blood pressure (SBP/DBP), left ventricular mass (LVM) in participants with essential hypertension. There was no significant difference between EIH and antihypertensive drugs in SBP (WMD: -0.44 [-2.30, 1.43]; P = 0.65), DBP (WMD: WMD: -0.02 [-1.13, 1.09]; P = 0.98) and LVM (WMD: -1.36 [-4.99, 2.26]; P = 0.46). Moreover, one trial showed that EIH combined with antihypertensive drugs was more effective in lowering blood pressure than those antihypertensive drugs used alone. However, the findings were limited by the small sample sizes, duration and low methodological quality of the trials. This is the first systematic review of EIH on essential hypertension. More rigorous RCTs with high quality are still needed to prove the effectiveness and safety of EIH and its preparations for essential hypertension.

Abstract
Objective: Hypertension is a risk factor for peripheral artery disease (PAD). Serum leptin plays an important role in promoting endothelial dysfunction. The aim of this study is to investigate whether the leptin level is associated with PAD in hypertensive patients. Materials and Methods: Ninety-eight hypertensive patients were enrolled in this study. Ankle-brachial index (ABI) values were measured using an automated oscillometric device. Patients with an ABI value <0.9 were considered the low ABI group. C-reactive protein (CRP) was measured using standard enzymatic automated methods. Serum levels of human leptin were determined using a commercially available enzyme immunoassay. Results: Eighteen (18.4%) hypertensive patients were included in the low ABI group. Hypertensive patients in the low ABI group had higher serum creatinine (P < 0.001), CRP (P = 0.003), and leptin (P < 0.001) levels, higher prevalence of diabetes (P = 0.036), and current smoking (P = 0.034) than patients in the normal ABI group. Univariate linear regression analyses revealed that body weight (P = 0.014), waist circumference (P = 0.010), body mass index (P = 0.002), and logarithmically transformed CRP (log-CRP, P = 0.001) were positively correlated with serum log-leptin levels in hypertensive patients. Multivariate stepwise linear regression analysis showed that log-leptin (β = 0.439, adjusted R2 change = 0.224, P < 0.001) was also an associated factor of PAD in hypertensive patients. Conclusion: A higher log-leptin value is an independent predictor of PAD in hypertensive patients.

Abstract
Background Despite intensive anti-hypertensive treatment, overall control rates of only 30 ~ 50 % have been reported in patients with hypertension (HTN). However, clinical significance and angiographic characteristics of patients with uncontrolled HTN following Below-the-knee arteries (BTK) interventions in patients with critical limb ischemia (CLI) are not clarified yet as compared to those with controlled HTN. Methods A total 165 consecutive hypertensive patients with BTK lesions from August 2004 to November 2012 were enrolled for this study. Uncontrolled HTN was defined as a blood pressure of > 140 mmHg systolic and 90 mmHg diastolic under anti-hypertensive treatment. A total of 112 patients (67.8 %) had uncontrolled HTN. We compared the clinical and angiographic characteristics of patients with uncontrolled HTN following BTK interventions to those with controlled HTN at 12-month follow-up. Results The baseline characteristics are well balanced between the two groups. At 12 months, there was no difference in the incidence of mortality, target lesion revascularization (TLR), target extremity revascularization (TER), and limb salvage rate in both groups. However, amputation rates were higher in patients with controlled HTN (33.9 vs. 19.6 %, P = 0.045). Conclusion Regardless of blood pressure control, HTN itself was an independent risk factor for BTK lesions, suggesting more intensive medical therapy with close clinical follow up will be required for all BTK patients with HTN.

Abstract
The aims of this study were to evaluate factors influencing the distribution of ciprofloxacin in tissue of patients suffering from varying degrees of peripheral arterial disease (PAD). Blood and tissue samples were collected from patients undergoing debridement or amputation procedures and the amount of ciprofloxacin in them was determined using high-performance liquid chromatography. All patients were administered a 200-mg dose of intravenous ciprofloxacin prior to the debridement or amputation procedure. Data, including patient gender, age, type of diabetes, presence of neuropathy, medications taken, and severity of PAD were collected. These data were then analyzed to determine factors influencing the concentrations of ciprofloxacin in tissue of the lower limbs. The Kruskal-Wallis test, Spearman correlation, and chi-square test were used to relate covariates and fixed factors with the concentration of ciprofloxacin in tissue. Following bivariate analysis, a 3-predictor regression model was fitted to predict tissue concentrations of ciprofloxacin given information about these predictors. Blood and tissue samples were collected from 50 patients having an average age of 68 years. Thirty-three patients were males and 35 patients suffered from type 2 diabetes. The average number of medications that these patients were taking was 10. The majority of patients (n = 35) were suffering from severe PAD. Tissue concentrations of ciprofloxacin were mainly related to plasma concentrations of ciprofloxacin, number of medications that the patients were taking and severity of PAD.

Abstract
Systolic hypertension, the predominant form of hypertension in patients aged over 50-60 years, is a growing health issue as the Asian population ages. Elevated systolic blood pressure is mainly caused by arterial stiffening, resulting from age-related vascular changes. Elevated systolic pressure increases the risk of cardiovascular disease, mortality and renal function decline, and this risk may increase at lower systolic pressure levels in Asian than Western subjects. Hence, effective systolic pressure lowering is particularly important in Asians yet blood pressure control remains inadequate despite the availability of numerous antihypertensive medications. Reasons for poor blood pressure control include low awareness of hypertension among health-care professionals and patients, under-treatment, and tolerability problems with antihypertensive drugs. Current antihypertensive treatments also lack effects on the underlying vascular pathology of systolic hypertension, so novel drugs that address the pathophysiology of arterial stiffening are needed for optimal management of systolic hypertension and its cardiovascular complications.

Abstract
AIM To explore risk factors for peripheral arterial disease (PAD) as well as the association between toe blood pressure and subclinical and clinical central vascular disease in patients with type 2 diabetes. METHOD Toe brachial index (TBI) was cross-sectionally analyzed in 742 middle-aged (54-66 years) patients with type 2 diabetes as well as non-diabetic controls and related to other vascular measures (e.g. carotid intima media thickness (IMT), presence of carotid plaque, central arterial stiffness and left ventricular mass index) and previous cardiovascular events. RESULTS A TBI ≤ 0.7 was seen in 22% of the patients but only one patient had severe TBI reduction (TBI ≤ 0.3). The corresponding figures in the controls were 13% and 0%, respectively. Mean TBI was significantly lower in patients with type 2 diabetes than in controls (0.81 ± 0.14 vs. 0.87 ± 0.15, p<0.001). In patients with diabetes, a lower TBI was associated with increased central arterial stiffness (p<0.001), IMT (p<0.001) and carotid plaque (p<0.001) as well as with decreasing glomerular filtration rate (p<0.001). Lower TBI was found in patients with previous macrovascular ischemic events. Furthermore, TBI was negatively correlated with age (p<0.001), diabetes duration (p<0.001) and HbA1c (p=0.01). CONCLUSION PAD, assessed with TBI, is common in a Swedish middle-aged diabetes type 2 cohort, affecting about one-fifth. As ankle pressure may be confounded by falsely high values in patients with diabetes due to media calcification we conclude that information about TBI may improve the risk evaluation regarding arteriosclerotic disease in both small and large vessels in type 2 diabetes.

Abstract
BACKGROUND Clopidogrel, cilostazol, and aspirin were compared in terms of efficacy and safety for primary prevention of stroke in peripheral artery disease (PAD) patients. METHODS This retrospective cohort study analyzed data contained in the Taiwan National Health Insurance Bureau database for patients treated for PAD but not for stroke during 2002-2008. Patients were stratified according to treatment with aspirin, clopidogrel, cilostazol, or combined therapy. The primary efficacy and safety endpoints were stroke and hemorrhage. RESULTS Of the 931 patients enrolled in this study, 479 had received aspirin, 39 had received clopidogrel, 294 had received cilostazol alone, and 33 had received a cilostazol-based combined therapy. Compared to patients treated with aspirin, the patients treated with cilostazol had significantly lower all-stroke risk not only in the overall group (HR=0.66, 95% CI=0.48-0.90, p=0.0086), but also in the subgroup of patients with diabetes (HR=0.64, 95% CI=0.42-0.98, p=0.0394) and in the subgroup of patients with high cardiovascular risk (HR=0.66, 95% CI=0.46-0.95, p=0.0254). Additionally, compared to patients treated with aspirin, those treated with cilostazol did not have significantly more hemorrhagic events in the overall group, in the diabetes subgroup, or in the high cardiovascular risk subgroup. Clopidogrel, cilostazol-based combined therapy and aspirin did not significantly differ in terms of efficacy and hemorrhagic events. CONCLUSION Although this database study indicated that cilostazol therapy is an effective alternative treatment for primary prevention of stroke in PAD, further confirmation is needed in large, prospective, and randomized trials.

Abstract
BACKGROUND The development of peripheral arterial disease (PAD) is heterogeneous even in the presence of similar risk factors. Our aim was to determine whether inter-individual differences in leukocyte telomere length contribute to the susceptibility of PAD. METHODS A total of 485 patients with PAD (defined by the ankle-brachial index) and 970 age- and gender-matched controls were recruited from seven rural communities in Henan Province in China. The relative leukocyte telomere length was determined by a quantitative PCR-based method. Two common promoter variants of the hTERT gene were genotyped to assess their effects on telomere length and the risk of PAD. In vivo luciferase assay was performed to study the transcriptional activity. RESULTS After adjustment for vascular risk factors and genetic variants in the hTERT gene, individuals in the lowest and middle tertiles of telomere length had a significantly higher risk of PAD than did those in the highest tertile (odds ratio [OR] 1.73, 95% confidence interval [CI] 1.29-2.49 in the middle tertile; 3.15, 95%CI 2.31-4.29 in the lowest tertile). Haplotype analysis using the 2 variants (rs2735940 and rs2853669) showed that subjects with the at-risk C-C haplotype had shorter telomere length than those individuals with the T-T haplotype and consistently had 1.30-fold (OR 1.30, 95%CI 1.06-1.58; P=0.005) increased risk for PAD. The C-C haplotype had 43% lowered transcription activity of hTERT promoter (P<0.001). CONCLUSION The associations between the functional haplotype of hTERT gene and telomere length and the risk of atherosclerotic PAD suggested that mean leukocyte telomere length may independently serve as a potential predictor of PAD.

Abstract
Background We investigated the prevalence of low ankle brachial index (ABI) and the association of low ABI with pulse pressure among elderly community residents in China. Methods This population-based cross-sectional study was conducted in Beijing and recruited 2982 participants who were aged 60 years or older in 2007. Low ABI was defined as an ABI value less than 0.9 in either leg. Participants with or without stroke or coronary heart disease (CHD) were analyzed separately. The association between pulse pressure and low ABI was examined by using multiple logistic regression models. Results The prevalence of low ABI was 5.65% (4.24% among men and 6.52% among women; P = 0.0221) among participants without stroke or CHD and 10.91% (13.07% among men and 9.49% among women; P = 0.1328) among those with stroke or CHD. After adjusting for confounders, the odds ratio (95% CI) for each 5-mm Hg increase in pulse pressure was 1.19 (1.07, 1.33) and 1.10 (1.02, 1.20) for men and women, respectively, among participants without stroke or CHD and 1.17 (1.03, 1.34) and 1.15 (1.02, 1.30) for men and women with stroke or CHD. When pulse pressure was classified into quartiles and the lowest quartile was used as reference, the association between pulse pressure and low ABI remained positive in men and women. Conclusions Low ABI was prevalent among elderly Chinese, and pulse pressure was positively associated with low ABI.

Abstract
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.

Abstract
BACKGROUND The prevalence and clinical significance of orthostatic hypertension (OHT) remain largely undetermined in hypertensive patients. This study investigated the association of OHT and orthostatic hypotension (OH) with cardiovascular disease (CVD) and target organ damage (TOD) in hypertensive patients. METHODS A cross-sectional study was conducted in 4,711 hypertensives and 826 normotensives, aged 40-75 years. OHT was defined as an increase in systolic blood pressure (SBP) of > or =20 mm Hg, and OH was defined as either a reduction in SBP of at least 20 mm Hg or a reduction in diastolic BP (DBP) of at least 10 mm Hg during the first 3 min after standing. RESULTS Hypertension was only independently associated with a risk of OHT. After controlling for age, sex, and other confounders, OH was associated with peripheral artery disease (PAD) (odds ratio (OR) 1.49, 95% confidence interval (CI) 1.15-1.89, P < 0.01), left ventricular hypertrophy (LVH) (OR 1.48, 95% CI 1.12-1.93, P < 0.001), coronary artery disease (CAD) (OR 1.71, 95% CI 1.12-2.61, P < 0.01), and stroke (OR 1.72, 95% CI 1.19-2.34, P < 0.01), but OHT was only associated with PAD (OR 1.36, 95% CI 1.05-1.81, P < 0.05) and stroke (OR 1.76, 95% CI 1.27-2.26, P < 0.01). The adjusted OR for PAD, predicted by the quintiles of the orthostatic SBP changes, showed a J-shaped relationship in untreated hypertensive patients, as was also the case for LVH in hypertensive women. CONCLUSIONS OH is associated with CV risk; the associations of OHT with TOD and stroke in hypertensive patients still need to be confirmed in prospective studies.

Abstract
Objectives. To observe the short- and long-term outcomes after percutaneous coronary intervention (PCI) in octogenarians (>80 y.o.) at our institution. Method. All octogenarians who underwent PCI during the study period were retrospectively retrieved from our database and clinically followed. Major adverse cardiac (and cerebral) events (MAC(C)E) was considered as primary outcome. Results. From January 2003 to December 2007, 140 octogenarians (mean age: 85±3 y.o., 79% of male) underwent PCI and were clinically followed 14±11 months. Procedural success was obtained in 100 percent of patients with single vessel disease, in 96 percent of patients with double vessel disease, and in 75 percent of patients with triple vessel disease. In-hospital, 30 days, and one year MACE rates were 5%, 5%, and 10.7%, respectively. Impaired left ventricular (LV) ejection fraction (hazard ratio (HR) = 0.909, 95% confidence interval (CI) = 0.856 to 0.964, P = .002), diabetes mellitus (HR = 5.792, 95% CI = 1.785 to 18.796, P = .003), and low GFR (HR = 2.943, 95% CI = 1.161, to 7.464, P = .023) were independently associated with an increase risk of MACE at long-term followup.
Conclusion. Coronary angiography can be successfully performed in elderly patients with single and double vessel disease. The results in triple vessel disease are encouraging. Low LV function, diabetes, and impaired renal function increase the risk of long-term major adverse cardiac events.

Abstract
BACKGROUND Hypertension is an established risk factor for peripheral arterial disease (PAD), but the prevalence of this condition in hypertensive patients without comorbidities is unknown. METHODS In this study, we assess the prevalence and factors associated with PAD, and the usefulness of ankle-brachial index (ABI) in evaluating cardiovascular risk in hypertensive patients without cardiovascular or renal disease or previously known diabetes mellitus. We measured ABI in 972 nonclaudicant patients with hypertension, newly diagnosed glucose disorders, metabolic syndrome, obesity or a 10-year risk of cardiovascular disease death of 5% or more according to the Systematic Coronary Risk Evaluation System. RESULTS The prevalence of PAD (defined as ABI < or =0.90) and borderline PAD (defined as ABI 0.91-1.00) in hypertensive patients was 7.3% (39/532) and 23.7% (126/532), respectively. In a multivariate model, hypertension remained an independent factor associated with PAD (adjusted odds ratio 3.20; 95% confidence interval 1.56-6.58). There was no association between PAD and metabolic risk factors. SBP and pulse pressure increased linearly across subgroups of ABI (normal 0.91-1.00 and < or =0.90) in hypertensive patients (P < 0.001). CONCLUSION Subclinical PAD is common in hypertensive patients even without comorbidities. The measurement of ABI is an efficient method to identify patients with increased cardiovascular risk and worth performing to hypertensive patients, particularly those with pulse pressure above 65 mmHg. Uniform criterions of defining PAD and borderline PAD would aid physicians in clinical decision-making.
