Uncommon Cause of Internal Mammary Artery Pseudoaneurysm.

Background: Internal mammary artery pseudoaneurysms most commonly develop from thoracic penetrating trauma or procedures. However, other important etiologies should not be overlooked. Case Report: A 27-year-old female presented with antiphospholipid antibody syndrome, thrombotic microangiopathy, end-stage renal disease on hemodialysis, and epilepsy. On admission, the patient had pulseless electrical activity and hypertensive emergency. After the patient was successfully resuscitated, she developed status epilepticus. Laboratory workup on admission revealed a subtherapeutic international normalized ratio, elevated C-reactive protein and sedimentation rate, and acute anemia. Imaging showed a right-sided subdural hematoma with a midline shift and likely internal mammary artery pseudoaneurysm. Angiography demonstrated aneurysmal dilation, segmental narrowing, and a string of beads appearance. Because of our patient's demographics, string of beads appearance on diagnostic angiography, history of renal disease, and negative hepatitis serology, fibromuscular dysplasia was considered the etiology of the internal mammary artery pseudoaneurysm. The family opted for 2 burr holes and a subdural drain but declined further diagnostic and therapeutic interventions because of anoxic brain injury and poor prognosis. Conclusion: In this patient, the etiology of the internal mammary artery pseudoaneurysm was attributed to fibromuscular dysplasia. Although this patient's family chose comfort measures, treatment methods are available for internal mammary artery pseudoaneurysms.

Impact of patient and family engagement in improving continuous positive airway pressure adherence in patients with obstructive sleep apnea: a randomized controlled trial.

STUDY OBJECTIVES: The aim of the Improving CPAP Adherence Program was to assess the impact of a multidimensional treatment framework based on shared decision-making, patient activation, and caregiver engagement on improving long-term positive airway pressure (PAP) adherence in patients newly diagnosed with obstructive sleep apnea. METHODS: In this pilot study, patients aged ≥ 18 years with a new obstructive sleep apnea diagnosis who qualified for PAP treatment and lived with a caregiver were randomly assigned to receive either the multidimensional treatment (intervention, n = 28) or unrelated education (control group, n = 32). All patients and their caregiver participated in a group visit. The intervention group attended 4 structured sessions: interactive education, peer coaching, hands-on experience, and a semistructured motivational interview. The control group was educated on physical activity and lifestyle only. Objective PAP adherence data were obtained at baseline (day that they received PAP machine to group visit), group visit to 3 months, and 3-6 months. RESULTS: In an age-adjusted model, the mean daily use of PAP increased significantly over the 3 time periods (P = .03). Intervention-arm participants gained a mean 1.23 hours (95% confidence interval, 0.33-2.13) in PAP mean daily use between 3 and 6 months vs those in the control arm (P = .008). We saw no difference in the percentage of PAP adherence across time between the 2 arms. CONCLUSIONS: A multifaceted patient-centered intervention with caregiver engagement improved PAP adherence vs control levels, a beneficial effect sustained for the 6 months. Our findings suggest that caregivers, with the appropriate training, can improve patients' PAP adherence by providing a socially supportive environment.

Semistructured Motivational Interviews of Patients and Caregivers to Improve CPAP Adherence: A Qualitative Analysis.

STUDY OBJECTIVES: The aim of this qualitative analysis was to identify obstructive sleep apnea (OSA) patients' preferences, partner experiences, barriers and facilitators to positive airway pressure (PAP) adherence, and to assess understanding of the educational content delivered and satisfaction with the multidimensionally structured intervention. METHODS: A qualitative analysis was conducted on 28 interventional arm patients with a new diagnosis of OSA. They received a one-on-two semistructured motivational interview as the last part of a 60- to 90-minute in-person educational group intervention. The 10- to 15-minute interview with the patient and caregiver was patient-centered and focused on obtaining the personal and emotional history and providing support. We also assessed understanding of the OSA training plan, their commitment to it, and their goals for it. RESULTS: We identified four themes: OSA symptom and diagnosis, using the PAP machine, perceptions about the group visit, and factors that determine adherence to PAP. Patients experienced positive, negative, or mixed emotions during the journey from symptoms of OSA to PAP adherence. CONCLUSIONS: Our findings suggest that patients' and caregivers' positive experiences of PAP could be enhanced by a patient-centered interaction and that it was important to explicitly address their fears and concerns to further enhance use of PAP. Not only could caregiver support play a role in improving PAP adherence but also the peer coaching session has the potential of providing a socially supportive environment in motivating adherence to PAP treatment.

Evidence of disparity in the application of quality improvement efforts for the treatment of acute myocardial infarction: the American College of Cardiology's Guidelines Applied in Practice Initiative in Michigan.

BACKGROUND: Racial disparities exist in the management of patients with cardiovascular disease in the United States. The aim of the study was to evaluate if a structured initiative for improving care of patients with acute myocardial infarction (Guidelines Applied in Practice [GAP]) led to comparable care of white and nonwhite patients admitted to GAP hospitals in Michigan. METHODS: Medicare patients comprised 2 cohorts: (1) those admitted before GAP implementation (n = 1,368) and (2) those admitted after GAP implementation (n = 1,489). The main outcome measure was adherence to guideline-based medications/recommendations and use of the GAP discharge tool. chi(2) and Fisher exact tests were used to determine differences between white patients (n = 2,367) and nonwhite patients (n = 490). RESULTS: In-hospital GAP tool and aspirin use significantly improved for white and nonwhite patients. beta-Blocker use in hospital improved significantly for nonwhite patients only (66% vs 83.3%; P = .04). At discharge, nonwhite patients were 28% and 64% less likely than white patients to have had the GAP discharge tool used (P = .004) and receive smoking cessation counseling (P < .001), respectively. Among white patients, GAP improved discharge prescription rates for aspirin by 10.8% (P < .001) and beta-blockers by 7.0% (P = .047). Nonwhite patients' aspirin prescriptions increased by 1.0% and beta-blocker prescriptions decreased by 6.0% (both P values nonsignificant). CONCLUSIONS: The GAP program led to significant increases in rates of evidence-based care in both white and nonwhite Medicare patients. However, nonwhite patients received less quality improvement discharge tool and smoking cessation counseling. Policies designed to reduce racial disparities in health care must address disparity in the delivery of quality improvement programs.

Cardiac amyloidosis treated with an implantable cardioverter defibrillator and subcutaneous array lead system: report of a case and literature review.

BACKGROUND: Preventing ventricular arrhythmias in patients with cardiac amyloidosis is challenging since the amyloid protein deposition in the myocardium may interfere with the normal cardiac electric excitation. Most of these patients succumb to either progressive congestive heart failure, or sudden cardiac death (SCD). Implantable cardioverter defibrillator (ICD) offers a near sure means of preventing SCD. HYPOTHESIS: Myocardial infiltration with amyloid results in elevated defibrillation threshold (DFT). Intra-operative strategies may fail to lower DFT during implantation. METHODS: We present a case of a 64-year-old female who had cardiac amyloidosis, and was successfully treated with an ICD and a subcutaneous array lead system. CONCLUSION: A subcutaneous array lead system is useful in reducing the DFT, and can terminate ventricular tachycardia or fibrillation by allowing more energy delivery and efficient defibrillation.

Does outpatient telephone coaching add to hospital quality improvement following hospitalization for acute coronary syndrome?

BACKGROUND: Telephone counseling in chronic disease self-management is increasing, but has not been tested in studies that control for quality of medical care. OBJECTIVE: To test the effectiveness of a six-session outpatient telephone-based counseling intervention to improve secondary prevention (behaviors, medication) in patients with acute coronary syndrome (ACS) following discharge from hospital, and impact on physical functioning and quality of life at 8 months post-discharge. DESIGN: Patient-level randomized trial of hospital quality improvement (QI-only) versus quality improvement plus brief telephone coaching in three months post-hospitalization (QI-plus). DATA: medical record, state vital records, patient surveys (baseline, three and eight months post-hospitalization). ANALYSIS: pooled-time series generalized estimating equations to analyze repeated measures; intention-to-treat analysis. PARTICIPANTS: Seven hundred and nineteen patients admitted to one of five hospitals in two contiguous mid-Michigan communities enrolled; 525 completed baseline surveys. MEASUREMENTS: We measured secondary prevention behaviors, physical functioning, and quality of life. RESULTS: QI-plus patients showed higher self-reported physical activity (OR = 1.53; p = .01) during the first three months, with decline after active intervention was withdrawn. Smoking cessation and medication use were not different at 3 or 8 months; functional status and quality of life were not different at 8 months. CONCLUSIONS: Telephone coaching post-hospitalization for ACS was modestly effective in accomplishing short-term, but not long-term life-style behavior change. Previous positive results shown in primary care did not transfer to free-standing telephone counseling as an adjunct to care following hospitalization.
