Pelvic artery aneurysm screening provides value in patients with thoracic aortic aneurysms.

Approximately » of patients with thoracic aortic aneurysms (TAAs) have concomitant abdominal aortic aneurysms (AAAs), thereby justifying the addition of an abdominal CT scan to a chest CT scan in patients with a newly diagnosed or suspected TAA. However, the prevalence of pelvic artery aneurysms (PAAs) in these patients is unknown. The purpose of this study was to determine the prevalence of PAAs in patients with TAAs and to assess what patient specific factors were associated with PAAs, thereby providing insight into the usefulness of pelvic imaging in TAA patients. Consecutive non-operated patients seen in Cardiac Surgery clinic between 2008 and 2013 with a TAA and a CT scan of the chest/abdomen/pelvis were included. Scans of 371 patients were evaluated for PAAs using threshold diameters of 20 and 15 mm for common iliac artery aneurysms (CIAs) and internal iliac artery aneurysms (IIAs), respectively, on 3D analysis. The prevalence of PAAs was determined and multiple logistic regression was used to identify associated risk factors. 41 of 371 (11.1%) patients with a TAA had at least one PAA. Factors showing positive associations with PAAs included increased age (p = 0.0004), male gender (p = 0.0007), descending TAA location (p = 0.0024) and presence of an AAA (p < 0.0001). The results of our study suggest that the addition of pelvic imaging for PAA screening in patients undergoing an initial CT scan of the chest and abdomen for a TAA is valuable, particularly in patients with the following demographics: age ≥65, male gender, descending TAA location, and/or known AAA.

Evaluation for abdominal aortic aneurysms is justified in patients with thoracic aortic aneurysms.

Aortic aneurysms are a significant cause of mortality, and the presence of multiple aneurysms may affect treatment plans. The purpose of this study was to determine the frequency of abdominal aortic aneurysms (AAAs) in patients with thoracic aortic aneurysms (TAAs) and to establish whether patient specific factors, such as gender and comorbidities, influenced the frequency of AAAs, thereby indicating if and when abdominal aortic evaluation is justified. Electronic medical records were reviewed from 1000 patients with a computed tomography (CT) angiogram of the chest and abdomen and a clinical diagnosis of TAA from Cardiac Surgery clinic between 2008 and 2013. 538 patients with history of aortic intervention, dissection, rupture or trauma were excluded. The frequency of AAAs among the 462 remaining patients was established, and statistical analysis was used to elucidate differences in frequency based on age, gender, comorbidities, and TAA location. Overall, 104 of 462 (22.5 %) patients with a TAA also had an AAA. There were significant differences in the frequency of AAA based on TAA location, age, and comorbidities. The following comorbidities showed positive associations with AAA using logistic regression analysis: age ≥65 (P < 0.0001; OR 30.1; CI 7.14-126.61), smoking history (P < 0.0001; OR 4.1; 2.35-7.30), and hypertension (P = 0.024; OR 2.1; CI 1.11-4.16). Aneurysms in the proximal/mid descending (P < 0.0001; OR 4.96; CI 2.32-10.61) and diaphragm level (P < 0.0001; OR 38.4; CI 14.71-100.15) of the aorta also showed a positive association with AAAs when adjusted for age and gender. AAA screening in patients with TAA is a reasonable, evidence-based option regardless of the TAA location, with the strongest support in patients >age 55, with systemic hypertension, a smoking history and/or a TAA in the descending thoracic aorta.

Evaluation of a postdischarge coronary artery disease management program.

OBJECTIVES: We conducted a demonstration project to assess the value of a nurse practitioner (NP) based coronary artery disease management (CAD-DM) program for patients with an acute coronary syndrome (ACS) or percutaneous coronary intervention. METHODS: Patients were recruited to attend three 1-h monthly visits. The intervention included assessment of clinical symptoms and guideline-based treatments; education regarding CAD/ACS; review of nutrition, exercise, and appropriate referrals; and recognition of significant symptoms and emergency response. RESULTS: Two hundred thirteen (84.5%) completed the program. Physician approval for patient participation was 99%. Average age was 63 ± 11 years, 70% were male, and 89% white. At baseline, 61% (n = 133) had one or more cardiopulmonary symptoms, which declined to 30% at 12 weeks, p < .001. Sixty-nine percent attended cardiac rehabilitation or an exercise consult. Compared to the initial assessment, an additional 20% were at low-density lipoprotein cholesterol < 70 mg/dL (p = .04), an additional 35% met exercise goals (p < .0001), and there was an improvement in the mental (baseline 49.7 vs. 12 weeks 53, p = .0015) and physical components (44 vs. 48, p = .002) of the SF-12 health survey. CONCLUSION: This NP-based CAD-DM program was well received and participants demonstrated improvement in physical and mental health, and increased compliance with recommended lifestyle changes.

Elective inguinal hernia repair: a unified informed consent, or who wants to know what?

Informed consent is increasingly being standardized. We sought to evaluate variability in the amount and quality of information desired by patients in choosing whether to undergo elective surgical hernia repair, a prototypical low- to moderate-risk common procedure. Consecutive stable outpatients were asked to assume that they were considering hernia repair and interviewed with a standard questionnaire that asked them to rate their interest in learning about the natural history, pathology, and management of inguinal hernia as well as herniorrhaphy complications and postoperative recovery. Ninety-eight consecutive patients exhibited substantial interpersonal variability in their level of interest in receiving information. Although interest in some types of information tended to correlate with interest in other types of information, patients' degree of interest in receiving information about anesthesia during the procedure was independent of other variables. Education and previous exposure to individuals with hernias also affected interest in receiving potentially important information before deciding whether to consent to hernia surgery. Patients may vary with regard to the information they want to receive when deciding whether to consent to an invasive procedure. It may be preferable to individualize the consent process to patients' preferences rather than adhering to standardized content.

Role of statin therapy in stroke prevention.

Serum cholesterol levels have been associated with atherosclerosis and the lowering of serum cholesterol with hydroxy-methyl coenzyme A reductase inhibitors, or statins, has been shown to decrease cardiovascular events. Though early epidemiologic data found conflicting results regarding serum cholesterol levels and stroke, randomized clinical trials of statins for coronary heart disease prevention showed a clear reduction in the incidence of stroke. This review summarizes the clinical trial data surrounding lipid lowering for stroke prevention while also exploring potential mechanisms for such an effect. Particular attention is given to trials for primary and secondary prevention of stroke relevant to the hypertensive individual, and the impact of hemorrhagic vs. ischemic stroke in the outcomes of these trials.
