Underuse of Prevention and Lifestyle Counseling in Patients With Peripheral Artery Disease.

ABSTRACT: BACKGROUND:Little is known about patterns of medication use and lifestyle counseling in patients with peripheral artery disease (PAD) in the United States. OBJECTIVES:The authors sought to evaluate trends in both medical therapy and lifestyle counseling for PAD patients in the United States from 2005 through 2012. METHODS:Data from 1,982 outpatient visits among patients with PAD were obtained from the National Ambulatory Medical Care Survey and National Hospital Ambulatory Medical Care Survey, a nationally representative assessment of office-based and hospital outpatient department practice. Trends in the proportion of visits with medication use (antiplatelet therapy, statins, angiotensin-converting enzyme inhibitors [ACEIs] or angiotensin receptor blockers [ARBs], and cilostazol) and lifestyle counseling (exercise or diet counseling and smoking cessation) were evaluated. RESULTS:Over the 8-year period, the average annual number of ambulatory visits in the United States for PAD was 3,883,665. Across all visits, mean age was 69.2 years, 51.8% were female, and 56.6% were non-Hispanic white. Comorbid coronary artery disease (CAD) was present in 24.3% of visits. Medication use for cardiovascular prevention and symptoms of claudication was low: any antiplatelet therapy in 35.7% (standard error [SE]: 2.7%), statin in 33.1% (SE: 2.4%), ACEI/ARB in 28.4% (SE: 2.0%), and cilostazol in 4.7% (SE: 1.0%) of visits. Exercise or diet counseling was used in 22% (SE: 2.3%) of visits. Among current smokers with PAD, smoking cessation counseling or medication was used in 35.8% (SE: 4.6%) of visits. There was no significant change in medication use or lifestyle counseling over time. Compared with visits for patients with PAD alone, comorbid PAD and CAD were more likely to be prescribed antiplatelet therapy (odds ratio [OR]: 2.6; 95% confidence interval [CI]: 1.8 to 3.9), statins (OR: 2.6; 95% CI: 1.8 to 3.9), ACEI/ARB (OR: 2.6; 95% CI: 1.8 to 3.9), and smoking cessation counseling (OR: 4.4; 95% CI: 2.0 to 9.6). CONCLUSIONS:The use of guideline-recommended therapies in patients with PAD was much lower than expected, which highlights an opportunity to improve the quality of care in these high-risk patients.

Project description:Background Underuse of cardiovascular medications for secondary prevention among individuals with peripheral artery disease (PAD) has been reported. Little is known about PAD treatment status in the Hispanic/Latino population in the United States, who may have limited access to health care and who have worse clinical outcomes than non-Hispanic individuals. Methods and Results We studied the use of cardiovascular therapies in 1244 Hispanic/Latino individuals recruited from 4 sites in the United States, including 826 individuals who reported diagnosis of PAD by physician and 418 individuals with coronary artery disease alone, in the Hispanic Community Health Study/Study of Latinos. We compared the prevalence of using antiplatelet therapy, lipid-lowering therapy and antihypertensive therapy by PAD and coronary artery disease status. Among those with PAD, we studied factors associated with taking cardiovascular medications, including demographic and socioeconomic factors, acculturation, access to health care and comorbidities, using multivariable regression models. The overall prevalence for individuals with PAD taking antiplatelet therapy, lipid-lowering therapy and, among hypertensive individuals, antihypertensive therapy was 31%, 26% and 57%, respectively. Individuals of Mexican background had the lowest use for all classes of cardiovascular medications. Older age, number of doctor visits and existing hypertension and diabetes mellitus were significantly associated with taking cardiovascular therapies in adjusted models. Compared with those with PAD alone, individuals with PAD and concurrent coronary artery disease were 1.52 (95% CI, 1.20-1.93) and 1.74 (1.30-2.32) times more likely to use antiplatelet agents and statins according to multivariable analysis. No significant difference of antihypertensive medication use was found among PAD patients with or without coronary artery disease. Conclusions Hispanic/Latino individuals with known PAD underuse cardiovascular medications recommended in clinical guidelines. More efforts should be directed to improve treatment in this important group.

Project description:BackgroundEndovascular atherectomy enables minimally invasive plaque removal in peripheral artery disease (PAD).AimsWe aimed to evaluate the safety and the long-term effectiveness of the Phoenix atherectomy for the treatment of complex and calcified lesions in PAD patients.MethodsConsecutive all-comer patients with PAD underwent the Phoenix atherectomy. Device safety in terms of perforation and distal embolisation were evaluated. Lesion calcifications were categorised by the Peripheral Arterial Calcium Scoring System (PACSS) and lesion complexity was assessed by the Transatlantic Inter-Society Consensus (TASC). Clinically driven target lesion revascularisation (TLR) was assessed.ResultsA total of 558 lesions were treated in 402 consecutive patients. Clinical follow-up was available at 15.7±10.2 months for 365 (91%) patients. Of 402 patients, 135 (33.6%) had claudication, 37 (9.2%) had ischaemic rest pain and 230 (57%) exhibited ischaemic ulcerations. Lesions were mostly identified in the femoropopliteal segments (55%), followed by below-the-knee (BTK) segments (32%). Complex TASC C/D lesions and moderate to severe calcifications (PACSS score ≥2) were present in 331 (82%) and 323 (80%) patients, respectively. The mean lesion length was 20.6±14.3 cm. Five (1%) perforations and 10 (2%) asymptomatic embolisations occurred. Bail-out stenting was performed in 4%, 16% and 3% of patients with common femoral artery, femoropopliteal and BTK lesions, respectively. During follow-up, 5 (3.9%) patients with claudication and 52 (21.9%) patients with critical limb-threatening ischaemia (CLTI) died (hazard ratio [HR] 3.7; p<0.001). Freedom from TLR was 87.5% (112 of 128) in patients with claudication and 82.3% (195 of 237) in patients with CLTI, respectively (HR 1.8; p=0.03).ConclusionsThe Phoenix atherectomy can be safely performed in patients with complex lesions with a relatively low rate of bail-out stenting and clinically acceptable TLR rates.German clinical trials registerDRKS00016708.

Project description:ObjectiveAn individual's understanding of disease risk factors and outcomes is important for the ability to make healthy lifestyle choices and decisions about disease treatment. Peripheral artery disease (PAD) is a condition with increasing global prevalence and high risk of adverse patient outcomes. This study seeks to understand the adequacy of disease understanding in patients with PAD.MethodsThis was an observational study of patients with PAD recruited from vascular surgery outpatient clinic and PAD clinical studies at a single academic medical center over an 8-month period. A 44-item paper survey assessed demographic and socioeconomic information, knowledge of personal medical history, PAD risk factors, consequences of PAD, and health education preferences. Patients with documented presence of PAD were offered the survey. Patients unable to complete the survey or provide informed consent were not considered eligible. Disease "awareness" was defined as correct acknowledgement of the presence or absence of a disease, including PAD, in the personal medical history. "PAD knowledge score" was the percentage of correct responses to questions on general PAD risk factors and consequences. Of 126 eligible patients, 109 participated. Bivariate analysis was used to study factors associated with awareness of PAD diagnosis. Factors associated with the PAD knowledge score were studied using the Pearson correlation coefficient, two-sample t test, or one-way analysis of variance. P value < .05 was considered statistically significant.ResultsThe mean participant age was 69.4 ± 11.0 years, and 39.4% (n = 43) were female. Most participants (78.9%; n = 86) had critical limb-threatening ischemia. Only 65.4% (n = 70) of participants were aware of a diagnosis of PAD, which was less than their awareness of related comorbidities. Factors positively associated with PAD diagnosis awareness were female sex (81.4% vs 54.7%; P = .004) and history of percutaneous leg revascularization (78.6% vs 47.9%; P = .001). Among 17 patients who had undergone major leg amputation, 35% (n = 6) were unaware of a diagnosis of PAD. PAD knowledge scores correlated positively with an awareness of PAD diagnosis (59.1% vs 48.7%; P = .02) and negatively with a history of hypertension (53.4% vs 68.1%; P = .001). Most participants (86.5%; n = 90) expressed a desire to be further educated on PAD. The most popular education topics were dietary recommendations, causes, and treatment for PAD.ConclusionsPatients with PAD have deficits in their awareness of this diagnosis and general knowledge about PAD. Future research priorities should further define these deficits and their causes in order to inform new strategies that foster information-seeking behavior and effective educational programs for PAD.
